Detailed use of transfer window of super clean working typhoon shower

Air filter is mainly used for air intake purification to remove dust particles In addition, the exhaust gas of some production processes contains small pollutants (such as radioactive substances, oil mist, etc.) although this kind of purification belongs to exhaust gas purification, because of its high purification requirements, it also needs to use air filter The characteristics of intake air purification are low dust concentration, fine dust particles and high purification efficiency According to different purification efficiency, classification and performance of air filter Note: general filter adopts air dust counting method, and filter adopts DOP method It can also be divided according to the specific purpose, characteristics and structure of the air filter, such as: (1) primary air filter purpose: the primary filter section of general ventilation air treatment equipment or the primary filter of fresh air system Features: the filter material can be replaced by itself, and the primary effect of paper frame is one-time (2) Folding medium efficiency air filter application: filtration of ventilation system General air purification in the fields of electronics, pharmacy, mechanical instrument, metallurgy, petroleum, chemical industry, light industry, food, etc Features: high efficiency, large dust capacity and small space occupation (3) Application of bag type medium efficiency air filter: central air conditioning centralized ventilation system, or as the pre filter of the filter, it can reduce the burden of the filter, extend its service life, and also can be used for general air purification in the industrial field Features: small resistance and large dust capacity (4) activated carbon filter uses: effectively remove odors, volatiles, bacteria, viruses and all kinds of pollutants in the air, such as paint spray, smoke, electronic factories and museums common pollutants, as well as the smell of food processing factories and hospitals Features: highly developed microporous structure, high adsorption capacity, fast adsorption and desorption speed, and good purification effect The use of activated carbon filtration must have a pre-stage filtration, otherwise, the efficiency of activated carbon will be reduced due to other pollutants in the air (5) Application of nylon mesh air filter: the ventilation and air conditioning system with low air quality requirements, or the place with poor surrounding environment and high dust are used as primary pre filtration Features: small resistance, easy to clean, easy to maintain (6) Application of sub air filter: all kinds of clean Engineering and central air conditioning with special requirements and end filtration of process air supply system or filtration of clean room Features: high filtration efficiency, low resistance and large dust capacity (7) Air filter application: clean air conditioning system, high cleanliness environment Features: high efficiency and small resistance (8) Application: high performance filter at the end of air conditioning box Features: high filtration efficiency, large air volume and large dust capacity (9) Use: air conditioning system with low air quality requirements, or places with poor surrounding environment, large dust and grease as primary pre filtration Features: durable, easy to clean (10) Application of air filter air supply outlet: it is suitable for clean rooms with various cleanliness levels and ceiling structures of non laminar flow Features: reliable performance, easy installation, disassembly and maintenance (11) Application of air filter unit with fan: it is suitable for sterile operating room of hospital and manufacturing fields of electronics, biology, medicine, food, etc Features: hanging under the floor, the cleaning effect can reach 10000 or 100000, saving room space, suitable for local purification, especially for the environment where the food industry often needs to wash the floor (12) Use and characteristics of air shower: air shower is a personal purification device used by operators when entering the clean room It uses the high-speed clean air flow to blow out the dirt on the indoor personnel The nozzle can be adjusted so as to effectively remove the dust on the human body and prevent the external pollution from entering the clean area It can also be used to blow and drench large goods (13) Purpose and characteristics of transfer window: a device for transferring articles set up in the clean area to reduce the number of opening doors, which reduces the pollution of the clean room to a low level of Zui It is mainly used for the transfer of small items between different levels of clean areas and between clean areas and non clean areas (14) Application: it is suitable for removing the surface pollution of objects by using high-speed clean air flow before entering the clean area, or for transferring the high cleanliness requirements between the clean area and the non clean area Features: the nozzle can be adjusted to directly aim at the object for spraying, effectively remove the object pollution, and prevent the external pollution from entering the clean area (15) Application and characteristics of super clean table: super clean table is a kind of general local purification equipment It can effectively eliminate the harmful effects of suspended particles and process dust in the air of the working area on the products, and is widely used in the fields of medical treatment, pharmacy, chemical experiment, electronics, precision instruments, food and cosmetics According to the material of the air filter, different types can be divided into the following types: (1) foam plastic filter foam plastic filter adopts polyethylene or polyester foam plastic filter layer Foam plastics should be chemically treated in advance to penetrate the inner pores and make them have a series of connected pores Due to inertia, diffusion and other functions, dust adheres to the wall of the hole to purify the air The internal structure of foam plastics is similar to that of loofah, with an aperture of about 200 mu m~300 m Plastic foam and organic solvent contact, otherwise easy to expand damage It can resist weak acid and alkali Gasoline, machine oil and lubricating oil have no effect on it (2) fiber filled filter fiber filled filter is composed of frame and filter material According to the different requirements of purification efficiency and resistance, various fibers of different thickness should be used as fillers, such as glass fiber (about 10 μ m in diameter), synthetic fiber (polystyrene), etc Filling density has a great influence on efficiency and resistance Filter thickness and filling density shall be determined according to specific requirements (3) Fiber felt filter this kind of filter is made of various fibers (such as polyester, vinylon, etc.) non-woven fabric (felt) as filter material It is usually made into bag type or winding type The bag type fiber felt filter is made of non-woven fabric filter material into foldable or V-shaped filter bag to expand the filtering area and reduce the filtering wind speed It has a high purification efficiency and is often used as a medium efficiency filter This filter has many shapes The air volume of each monomer is about 200m3 / h, the filtering wind speed is about 20cm / s, and the weighing efficiency of artificial dust is 80% The automatic winding filter can be made of foam plastic or nonwoven fabric as filter material, and each roll of filter material is about 20m long The filter is composed of upper and lower boxes, vertical frames, retaining bars, transmission mechanism and filter material rolls After the filter material has accumulated dust, it can be automatically rolled and renewed until the whole filter material has accumulated dust, and then it can be taken down and replaced Each roll of filter material can normally be used for 8 months to 1 year (4) Paper filter paper filter is a kind of sub filter The filter paper used for filtration includes: ① plant cellulose filter paper (used for sub filter); ② bluestone cotton fiber Jingwei filter paper (used for filter); ③ ultra-fine glass fiber filter paper (used for sub filter) Due to the high resistance of the filter paper and the low filtering wind speed, in order to increase the filtering area, the filter paper can be folded and separated by a corrugated partition plate in the middle The partition board can be made of kraft paper by hot rolling or plastic or aluminum plate The outer frame can be made of wood, plastic, aluminum, steel and other materials.
