Clean workshops generally include equipment areas (including rooms for purifying air-conditioning systems, electrical rooms, rooms for high-purity water and high-purity gas, rooms for cooling and heating equipment, etc.), management areas (including offices, duty, management, and restrooms, etc.), clean rooms Auxiliary rooms (including personnel purification rooms, material purification rooms and some living rooms, etc.), production areas. The last three types of buildings are all facilities that serve clean production areas.
1. Clean auxiliary room, which is an indispensable room for clean workshops. The air cleanliness levels of these rooms are designed according to the requirements of customers, and are designed in accordance with the regulations in the "Code for Design of Clean Plants" GB50073-2001.
2. Equipment area, that is, rooms for purification air-conditioning systems, public power systems, etc. This part is an important part of the clean workshop. At present, in the design of clean workshops, purifying air-conditioning equipment, cooling and heating (excluding boiler rooms) equipment, and water and electricity facilities are often arranged in clean workshops, which is convenient for management and can reduce pipeline length.
3. Clean production area, which is the main part of the clean workshop. The air cleanliness level of the clean production area is determined according to the product production process requirements. This is the main basis for the design of clean building workshops. In addition to providing construction drawings, please provide the production Various design conditions of the product, such as temperature, humidity, air flow pattern requirements, the nature of the raw and auxiliary materials required for production and the requirements of water, electricity, and gas, noise, vibration, static electricity and other environmental conditions and requirements.
4. Management area. This is the room for production management, technical management and necessary rest and welfare for the operators in the clean workshop. Wuxi Chengyi Purification Equipment Co., Ltd. can design according to customer requirements.

The main function of the purification workshop is to control the cleanliness, temperature and humidity of the atmosphere that products (such as silicon chips, etc.) are exposed to, so that the products can be produced and manufactured in a good environmental space. We call this space the purification space.
Jiangsu Yanxin Environmental Technology Co., Ltd. provides assembly clean rooms (cleanliness levels of 100 to 300,000), series of clean benches, air showers, high-efficiency vents, laminar flow hoods, sampling vehicles, primary, middle, and high-efficiency Air filters, aluminum alloy vents, diffusers, regulating valves, mufflers, series of multifunctional air conditioners and other products and accessories required for purifying air conditioners. It has engineers, researchers, technicians and a number of professional purification projects, dust-free workshops, and a well-trained construction team with rich experience in purifying air-conditioning construction. With strong technical force, it enjoys a high reputation in the industry and is trusted and respected by customers.

Relatively mechanical filtration can only effectively remove particles above 10 microns, and when the particle size is reduced to 5 microns, 2 microns or even sub-micron, high-efficiency mechanical filtration systems will become more expensive, and Wind resistance will increase significantly. Filtered by the electrostatic electret air filter material, it can achieve high capture efficiency with low energy consumption. At the same time, it also has the advantages of electrostatic dust removal and low wind resistance. Its composition is made of polypropylene, which is convenient for disposal.

Temple University in the US theorised that by applying an electric field they could accomplish two things - reduce the viscosity enough to lower the fat content, but also increase the density of the particles to maintain proper flow of chocolate through the manufacturing process.The key was to apply the electric field in the same direction as the flow of the chocolate. Traditionally, electrorheology (ER), the practice of using electric fields on liquids, works perpendicularly to the liquid flow direction.
Researchers believe this method could be applicable to any liquids for which there is a need to reduce viscosity.In previous research, scientists used an electric field to thin fuel to improve the transportation of crude oil via pipeline and improve gas efficiency in the engine and a magnetic field to thin blood to help prevent heart attacks.Electrorheology works by changing the alignment of the particles in a liquid using electric fields, researchers said.In the current study, ER aggregated the cocoa solid particles into short chains, which allowed the scientists to reduce the viscosity and fat content but maintain the flow.For precision, researchers invented their own device to test their theory.

China Quality Certification Center (CQC) officially released the "Air Purifier Environmental Protection Certification Rules" with the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center. "Air Purifier Environmental Certification Rules" based on the adoption of the standard GB18801, citing the relevant requirements of GB21551.3-2010 "Special requirements for antibacterial, sterilizing and purifying function air purifiers for household and similar electrical appliances", in accordance with the fifth This certification mode certifies the purification function of air purifiers to meet consumers’ overall needs for safety and environmental protection of air purifiers. Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center, said that because the country has no comprehensive evaluation method for the purification effect of air purifiers, air purifiers only have safety certifications, and there are no relevant certifications for purification functions. Simple safety certification can no longer satisfy consumers’ pursuit of clean, healthy, and environmentally-friendly living rooms. Therefore, there is an urgent need for third-party organizations to formulate unified evaluation and certification criteria for air purifiers. The promulgation and implementation of this rule will effectively purify the market, help companies build brands, and promote the healthy development of China’s purifier market.

The shape of the air purifier is mainly the case shell, filter section, air duct design, motor, power supply, LCD screen, etc. It is the motor that determines the lifespan, the filter section determines the purification performance, and the air duct design, the housing, the filter section and the motor determine whether it is quiet.
The air purifier is mainly composed of a motor, a fan, an air filter, and an intelligent monitoring system. Some models of the machine are equipped with a humidifying water tank, or auxiliary purification devices, such as anion generator, high-voltage circuit, etc. The air filter is the core component. Other purification devices actually only play an auxiliary function, so the quality of the air filter is the most critical factor that directly affects the effect of the air purifier.
Motor and fan: As the core and essential accessory of the air purifier, the motor fan is mainly used to control the circulation of air. The air with pollutants is sucked in, filtered, and then the clean air is blown out.
Air filter (filter): Most air purifiers on the market mainly achieve the purpose of purifying the air by filtering the filter, and the filter is mainly divided into: particulate filter and organic filter. The particulate filter is divided into coarse filter and fine particulate filter; the organic filter is divided into formaldehyde filter, deodorant filter, activated carbon filter and so on. Each type of filter mainly targets different sources of pollution, and the principle of filtration is also different.
Water tank: As air purifiers are getting more and more attention from consumers, the function of air purifiers is not only limited to air purification. By adding water tank structure design, the air purifier can not only complete the basic mission, but also treat the air. Play the role of humidification.
　　Intelligent monitoring system: The intelligent monitoring system is simply understood as an air quality supervisor. Through the built-in monitoring equipment, it can make a real-time judgment on the air quality. Consumers can choose to use air purifiers according to the air quality. In addition, the intelligent monitoring system can also monitor the life of the filter, the water level of the water tank, etc., so that users can understand the working status of the air purifier.
　　 Negative ion generator and high voltage circuit: generally used as an auxiliary purification function, mainly to send out negative ions with clean air. Negative ions have the functions of sedation, hypnosis, analgesia, increase appetite, and lower blood pressure. After the thunderstorm, people feel comfortable, because the negative ions in the air increase. Air negative ions can reduce the active oxygen (oxygen free radicals) produced by air pollutants, nitrogen oxides, cigarettes, etc., and reduce the harm of excessive active oxygen to the human body.
Disinfection device: In terms of its structure, electrostatic air purification device generally has three products on the market: flat structure air purification device, honeycomb hexagon channel air purification device, circular hole channel air purification and disinfection device.

Like water purifiers, air purifiers need to be cleaned regularly, and some need to replace filters and filters to maintain their purification effect. The maintenance and maintenance of air purifiers depends on different brands and types of air purifiers.
1. Filter type purifier:
1. The front filter (usually the back cover of the case) has been used for a long time, and some dust will be collected, which will affect the air intake and the effect of air purification. Therefore, you need to use a vacuum cleaner to suck away the dust, or use a rag to clean it, or even wash it with water.
2. Filters, some filters need to be exposed to the sun regularly to maintain the purification efficiency, such as activated carbon filters.
3. Deodorizing filter, the deodorizing filter of a few brands of air purifiers, in order to achieve the technical level of washing, it can be washed with water, that is, to maintain the purification efficiency and extend the cycle of filter replacement.
4. Ionizers are generally built-in and do not need to be cleaned. Better ionizers have higher working efficiency.
The dust filter or dust collecting plate in the air purifier should be cleaned frequently, generally once a week, and the foam or the plate should be washed and dried with soap liquid before use to keep the airflow unobstructed and hygienic. When there is a lot of dust on the fan and electrode, it should be cleaned up, and it is generally maintained every six months. A long-bristled brush can be used to remove the dust on the electrodes and wind blades. When the air purifier is not in use, it should be cleaned and packed into the packaging box and stored in a ventilated and dry place. At ordinary times, you should pay attention to moisture, so as not to reduce the efficiency or damage due to moisture.
2. Electrostatic purifier
Generally, it is simple to clean the electrostatic module or dust collection module. Wipe with a brush or cloth, or rinse in clean water and air dry.

In 1823, John and Charles Dean invented a new type of smoke protection device that allows firefighters to avoid smoke when fighting fires. To In 1854, a man named Johns Tenhouse made new progress based on the invention of his predecessors: after several attempts, he learned that adding charcoal to the air filter can filter out harmful and toxic gases from the air. . During World War II, the US government began to conduct research on radioactive materials. They needed to develop a way to filter out all harmful particles to keep the air clean so that scientists could breathe, so HEPA filters came into being. In the 1950s and 1960s, HEPA filters were once very popular. HEPA is a filtration standard, that is, it has a filtration efficiency of more than 99.97% for 0.3 micron particles, which requires a single filtration efficiency. In the air purifier, the air resistance of the filter that meets the HEPA standard is too high to be suitable. In the 1980s, the focus of air purification has shifted to air purification methods, such as household air purifiers. The old filters are very good at removing malodors, toxic chemicals and toxic gases in the air, but they cannot remove mold spores, viruses or bacteria. The new home and office air purifiers can not only clean the toxic gases in the air. It can also purify the air and remove bacteria, viruses, dust, pollen, mold spores, etc. in the air. Since the late 1990s, with the increasing demand for sterilization and deodorization, there has been a wave of "antibacterial fever" in the field of air purifiers. The air purifier also adopted a photocatalyst filter in 1996 to improve its sterilization and deodorization performance. After 2002, affected by the spread of SARS and the new influenza epidemic, people’s demand for anti-virus air purifiers has increased. Developed and equipped the air purifier with "Streamer Energy" technology. The air purifier technology uses decomposition (oxidation) filter elements to capture bacteria and viruses. In 2008, in addition to the countermeasures to remove harmful substances in the air, in order to meet the need to eliminate room dryness, the air purifier added a "humidification function". As of 2013, most air purifiers on the market, especially those with a value of less than 10,000 yuan, cannot be called "HEPA".

First of all, we should consider the use environment and the effect to be achieved. General indoor air pollution: 1. Allergens such as dust, viruses, bacteria, molds and mites; 2. Inhalable organic volatile gases, such as formaldehyde, benzene, ammonia, etc.; 3. Radon gas released from stratum and building decoration materials Radioactive pollution caused by its progeny. Therefore, when selecting air purification products, their functions and effects should be considered comprehensively.
Secondly, the purification capacity of the air purifier should be considered. If the room is large, you should choose an air purifier with a larger air volume per unit time. Generally speaking, a larger purifier has a stronger purifying ability. For example, a room of 30 square meters should choose an air purifier of 120 cubic meters per hour. When purchasing, you can refer to the introduction in the sample or manual to choose. Third, the service life of the purifier should be considered, and whether it is easy to maintain. If some products adopt the principle of filtration, adsorption, and catalysis, the filter inside the purifier becomes saturated with the air purifier as the use time increases, and the purification capacity of the equipment decreases. It is necessary to clean and replace the filter and the filter.
The purifying filter (including high-efficiency catalytic activated carbon) with regenerative capacity should be selected to extend the service life; some electrostatic products do not need to replace related modules, as long as they are cleaned regularly. Fourth, the match between the layout of the room and the purifier should be considered comprehensively. The design of the inlet and outlet wind of the air purifier has a 360 -degree ring design and a one-way design.

1. Filter material. Good filter materials (such as HEPA high-density filter materials) can absorb pollutants above 0.3 microns as high as 99.9%. 2. Purification efficiency. If the room is large, you should choose an air purifier with a large unit air volume. For example, for a room of 15 square meters, you should choose an air purifier with a unit air volume of 120 cubic meters per hour.
3. Service life. As the purifying filter becomes saturated, the adsorption capacity of the purifier will decrease, so consumers should choose a purifying filter with regeneration function to extend its life. Fourth, the room layout. The air inlet and outlet of the air purifier have a 360-degree circular design, and there are also unidirectional air inlets and outlets. If the product is not restricted by the room layout, you can choose a product with a circular inlet and outlet design. 5. Demand. Choose an air purifier according to the types of pollutants that need to be purified. HEPA has a strong purification function for smoke, suspended particles, bacteria, and viruses, and catalytic activated carbon has a better purification effect on peculiar smells and harmful gases. 6. After-sales service. After the purification filter fails, it needs to be replaced by the manufacturer, so you should choose the products of the enterprise with perfect after-sales service.

Also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde, etc.) , Bacteria, allergens, etc.), products that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building. There are many different technologies and media in air purifiers, which enable it to provide users with clean and safe air. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure light mineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Synthetic fiber, HEPA high-efficiency material, negative ion generator, etc. Most of the existing air purifiers are of composite type, that is, multiple purification technologies and material media are used at the same time.

1. Pregnant women: Pregnant women will feel general malaise, dizziness, sweating, dry tongue, chest tightness, vomiting and other symptoms when they are indoors with serious air pollution, which will adversely affect the development of the fetus. The probability of developing heart disease is three times that of children born to pregnant women who breathe fresh air.
2. Children: Children’s body is developing, and the immune system is relatively fragile and vulnerable to indoor air pollution, resulting in decreased immunity, delayed physical growth, induced blood diseases, increased the incidence of childhood asthma, and greatly enhanced children’s intelligence reduce. To
3. Office people: an enviable career when working in high-end office buildings. However, in a constant temperature and airtight environment with poor air quality, it is easy to cause dizziness, chest tightness, fatigue, emotional fluctuations and other uncomfortable symptoms, which affect work efficiency and cause various diseases. In severe cases, it can also cause cancer.
4. Elderly people: Older people decline in physical function and often suffer from many chronic diseases. Air pollution not only causes respiratory diseases such as bronchitis, pharyngitis and pneumonia in the elderly. It can also induce high blood pressure, heart disease, cerebral hemorrhage and other cardiovascular diseases. To
5. Patients with respiratory diseases: Long-term living in polluted air will cause a decline in respiratory function and aggravate respiratory symptoms, especially rhinitis, chronic bronchitis, bronchial asthma, emphysema and other diseases. By breathing pure air to achieve auxiliary and radical therapeutic effects. To
6. Driver: There is a lack of oxygen in the car, and the exhaust pollution of the car is serious.

When it comes to air quality indicators, the first reaction of most people should be PM2.5. This is also the main source of pollution in haze weather. PM2.5, also known as fine particles, is only particles with an equivalent diameter less than or equal to 2.5 microns in the air. It can be suspended in the air for a long time, and it is easy to carry toxic and harmful substances, which has a great impact on human health and environmental quality. However, as far as indoor air is concerned, only one PM2.5 indicator is too thin. According to the "White Paper on China’s Indoor Air Pollution Status in 2019", the top two sources of indoor air pollution are formaldehyde and VOC, accounting for 97.3% of the total unqualified points, which deserve our attention. Everyone knows about formaldehyde, especially after the renovation or the use of glue or paint, the indoor formaldehyde content is high. We will also pay attention to emission and removal of formaldehyde. But VOC is not clear to many people. VOC refers to volatile organic compounds. Another indicator name that you occasionally see is total volatile organic compounds. The U.S. Environmental Agency (EPA) defines VOC as: except for carbon monoxide, carbon dioxide, carbonic acid, metal carbides, carbonates and ammonium carbonate, any carbon-containing compound that participates in photochemical reactions in the atmosphere. Mainly from combustion products such as coal and natural gas, smoking, heating and cooking smoke. In interior decoration, it mainly comes from latex paint, wallpaper, floor, thermal insulation materials, adhesives, etc.

Exhaust gas purification mainly refers to the industrial waste gas generated in industrial sites, such as dust particles, smoke and dust, odorous gases, and toxic and harmful gases.The work of governance. Common exhaust gas purification includes factory smoke and exhaust gas purification, workshop dust and exhaust gas purification, organic exhaust gas purification, and exhaust gas Peculiar https://www.yanxinpurification.com/, acid and alkali waste gas purification, chemical waste gas purification, etc.
To Exhaust gas purification equipment is widely used in chemical plants, electronics plants, painting plants, automobile plants, coating plants, petrochemical industries, furniture plants, and food Plants, rubber plants, plastic plants and other industries that produce peculiar smells, odors, and toxic and harmful gases. The main types of gases purified by exhaust gas purification equipment are Organic waste gas such as benzene, toluene, xylene, ethyl acetate, acetone methyl ketone,ethanol, acrylic acid, formaldehyde, hydrogen sulfide, sulfur dioxide, ammonia Such as acid-base waste gas purification and organic waste gas purification.
To Exhaust gas purification methods mainly include activated carbon exhaust gas purification adsorption method, pharmaceutical absorption exhaust gas purification method, catalytic combustion exhaust gas purification method, and thermal combustion Exhaust gas purification method, plasma exhaust gas purification method, etc. When selecting exhaust gas purification methods, low cost, low energy consumption, and no cost should be selected according to the specific conditions. Secondary pollution, try to save energy consumption, is beneficial to environmental protection.

To put it bluntly, water purification equipment means that according to various physical and organic chemistry methods, some chemical substances that are harmful to the body are removed from the water. This kind of equipment has been cleaned and solved by water. We all know that water and health, water and people are closely related.
However, with the rapid development of industrial production, water pollution has become more and more serious. In today’s society, the water resources crisis composed of insufficient water sources and environmental pollution has become the complex problems encountered by all countries in the current policies, economic development and technology, and the key constraints of economic and social development. Therefore, in order to handle the water problems closely related to the development of people’s society in practice, it is necessary to adopt contemporary water treatment and water purification equipment. Water purification equipment can be divided into integrated MBR sewage treatment equipment, raw water purification equipment, purified water equipment, purification equipment, and ultrapure water equipment.
Water purification equipment like the following: purified water equipment, ultrapure water equipment, RO reverse osmosis purified water equipment, automatic water softeners, automatic dosing systems; mechanical filters, hollow chemical fiber ultrafiltration devices, ion exchange methods, mixing Bed, grinding and polishing mixed bed.
EDI electric desalination system software equipment; direct drinking water equipment for food, clothing, housing, transportation, ultraviolet light water processor, high-efficiency decontamination filter device, hand-operated brush filter device, self-cleaning brush filter device, frequency injection Filter, side stream processor, intelligent electronic descaler, vacuum pump degassing deaerator, bottom thermal deaerator, enclosed condensate water acquisition equipment, iron removal equipment, manganese purification equipment, copper and silver ion sterilizer, yellow Rust filter, fiber bundle filter device, ceramic membrane filter, high-efficiency fiber ball filter device, high-efficiency organic chemical deoiler, swimming pool circulating water treatment machinery and equipment, integrated water purification equipment for garden and landscape water, industrial sewage treatment solutions Machinery and equipment.
Industrial production integrated MBR sewage treatment equipment, clothing, food, housing and transportation integrated MBR sewage treatment equipment, aquaculture sewage treatment machinery and equipment, all belong to the water purification equipment widely used in daily life and a variety of industrial production. Water purification equipment, in a nutshell, is a kind of equipment that cleans the water resources that have environmental pollution. Water is the source of everything in the world, and one cannot live without water for a day. Water pollution will seriously endanger people’s physical and mental health, so protecting water resources starts with me.

Specifically, it can be carried out through the following 5 steps:
(1) The oil fume purification equipment products certified by CCC should be selected. As long as they have passed the CCC certification and posted the oil fume purifier products with the CCC symbol to enter the market, their safety is more reliable and the quality is more assured.
(2) Currently, there are three types of oil fume purifiers on the market: thin type, deep type, and cabinet type. The thin oil fume purifier is small in size, light in weight and easy to hang, but its exhaust power is significantly lower than the other two types of models. If the kitchen wall is thin (non-load-bearing wall) and cannot bear the weight of a deep range hood, and because of the constraints of the kitchen planning, it is impossible to install a cabinet-type range hood, you should choose a thin range hood. And families who usually like to cook food on high fires are best not to buy shallow-cover flat-type, ultra-thin type oil fume purifiers with low extraction rates. The deep-shaped oil fume purifier has a beautiful appearance, and its deep-shaped outer cover can suck cooking oil fume in a wide range and has a high smoke exhaust rate. Deep-type range hood ◇The volume and weight are relatively large, and the kitchen wall must have a certain thickness when hanging. The cabinet-type oil fume purifier is composed of a fume exhaust cabinet and a special oil fume purification equipment, with a high smoking rate, no need to hang, and there is no doubt about drilling equipment. But its baffle will affect the cooking operation.
(3) Check the quality of the oil fume purifier. Observe carefully for signs of scratches, bumps, paint peeling, etc. Plug in the power and check the operating status of the oil fume purifier. If the motor noise is small, the wind wheel is stable and the suction is large, it means that the oil fume purifier is working normally.
(4) Pay attention to the air volume, fan power and noise of the oil fume purifier. The air volume and fan power are not as large as possible. Under the premise of achieving the same extraction rate, the fan power and air volume should be as small as possible. This saves energy and electricity, and can achieve better mute effects.
(5) It is not that the more versatile the fume purifier, the more trustworthy it is. Nowadays, many oil fume purifiers are equipped with gas alarms, automatic switches and other equipment. Although their functions increase, their prices are higher, and the incidence of faults will increase accordingly. Some functions are actually not useful. For example, automatic switch equipment, which consists of a highly sensitive gas-sensitive switch, will lose its effect when the number of times it touches with oil fume reaches a certain limit.
