  1. Filter air speed The filter air speed of the bag type dust collector is too high, which is the main reason for the damage of the cloth dust collector bags. In recent years, some companies have blindly reduced equipment costs and increased profits: when designing a bag type dust collector, the filter air speed was increased. There was no obvious response in a short time, but the service life of the filter bag was greatly shortened. In this way, instead of saving money for customers, it brought a very large economic burden and wasted time.   2. Operating temperature The key to the filter bag is to select the cloth dust collector bags suitable for the corresponding dust temperature. If the temperature is too high, the selected cloth dust cloth collector bags will exceed the normal operating temperature, thus shortening the service life, and even burning the filter bag in a short time. Therefore, when selecting a filter bag, the inlet temperature of the dust collector must be measured

  The dust holding capacity of the dust collection bag is also called the dust volume accumulated on the filter material per unit area when the dust load value reaches a given resistance value. The dust holding capacity of the dust bag affects the resistance of the filter material and the length of the cleaning cycle. In order to avoid frequent dust removal of dust removal equipment, it is generally required that the dust capacity of the dust removal bag be larger. The dust capacity of the dust bag is related to the porosity and air permeability of the filter material. The felt filter material has a larger dust capacity than the fabric filter material does.   The relationship between the dust capacity of dust bag and filtration efficiency   Filter efficiency of cloth bags. On the one hand, the filter efficiency of the dust collection bag is related to the filter material structure, and on the other hand, it also depends on the dust layer formed on the cloth bag. From the point of view

    The bag type dust collector is a dry dust removal device, which is suitable for collecting fine, dry non-fibrous dust. Common filter bags include cloth dust collector bags, felt filter bags, which are made of woven filter cloth or non-woven felt. The filter property of fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag type dust collector, the particles Large and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified. Generally, the dust removal efficiency of new filter media is not high enough. After the filter material has been used for a period of time, due to the effects of sieving, collision, retention, diffusion, static electricity, etc., a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. In the subsequent movement process, the primary layer be

  Maintenance instructions for bag filter:   1. When the bag type dust collector is under maintenance, first cut off the power supply. The operator must carry the key of the operation panel and hang a sign "under maintenance, no operation" on the operation panel.   2. The transmission devices such as the rapping device, star unloader, exhaust fan, and couplings, transmission belts, transmission coupling wheels, etc., must be equipped with protective covers to prevent the bolts from loosening, causing the belts and chains broken to hurt people.   3. During the daily inspection or operation, the operator must strictly prevent the clothes from being twisted into the transmission device when handling the fault temporarily. When entering the ash collection hopper to clean the ash or entering the filter bag room to hang the bag, labor protection equipment must be worn to prevent dust from getting into the eyes or burning the skin.   4. For  bag type dust collector  that handle flam

    1. Introduction of PTFE filter bags PTFE is polytetrafluoroethylene, also known as Teflon, is one of the more high-end varieties of bag filter materials. The PTFE synthetic fiber filter bag is a filter bag made of a unique material. It can withstand acid and alkali corrosion in the entire PH value range at a continuous operating temperature of 240℃ and an instantaneous temperature of 260℃. The PTFE synthetic fiber filter bag has excellent self-lubricity, does not absorb moisture, and can withstand ultraviolet radiation. However, the wear resistance of the PTFE fiber filter material is general, so there are stricter requirements (finishness) for the filter bag frame. PTFE fiber filter bags are more suitable for harsh conditions that require corrosion resistance and high requirements for filter material service life.   Polytetrafluoroethylene synthetic fiber filter bags can be used for flue gas treatment in coal-fired boilers, garbage incineration, carbon black production, titanium d

  1. Introduction of polyester filter bag   In recent years, countries around the world have made many efforts in the treatment of environmental pollution and achieved great results. In the treatment of air pollution and material recovery, bag dust removal has achieved good results. The technical core of bag dust removal is the filter material. Bag dust removal is using polyester filter felt to filter the dust in the gas.   2. Performance requirements of polyester filter bag   People have many requirements for the performance of filter media of  polyester filter bag . The main performance requirements are: large air handling capacity, low resistance, long life, and low price.   The filter cloth used for dust filtration mainly consists of organic woven filter cloth and needle punched filter cloth.   Woven filter cloth is made of twisted warp and weft yarns interlaced on a plane, with a two-dimensional structure. The woven filter material requires a great degree of tightness when weaving

  Ⅰ. Introduction of P84 filter bags   P84 filter bag is a flame-retardant, temperature-resistant and stable fiber filter material. Under the condition of 240 ℃, the machine of P84 polyimide fiber filter material will not change, and the highest temperature can reach 260 ℃. P84 fiber filter material has no melting point temperature and is natural golden yellow. P84 polyimide fiber filter material is not a hygroscopic fiber filter material (under the condition of 65% relative humidity, about 3% water absorption).   In addition, because the P84 fiber has a special (leaf-shaped) cross-sectional structure, it has a large filtering surface area and excellent filtering performance, so P84 fiber is often implanted on the surface of the filter material (the side of the dust facing side to improve the filtering performance of the filter material. ).   Ⅱ. Several common factors for P84 filter bag damage:   1. Product quality   The processing of P84 filter bags  is the most important. In recent y

    1. Factors for choosing industrial dust collector   Relevant factors that need to be considered when choosing an industrial dust collector: such as dust removal efficiency, equipment location, and available space; equipment investment and economic factors such as operation and maintenance costs must also be considered, of which dust removal efficiency needs to be focused. In this regard, the selected industrial dust collector also needs to meet the emission concentration specified by the emission standard.     2. The basis for choosing industrial dust collector   1. Set up the basic parameters according to the local environmental protection and environmental assessment requirements, and use this as a requirement to seek qualified industrial and dust collector manufacturers to carry out specific dust removal plans and implementation.   2. Choose the corresponding dust removal equipment according to different working conditions;   a. For floating dust, dust collectors with large air
