With the development of science and technology, the strict requirements of environmental protection have been realized, the design of various large-scale bag filter has been continuously improved and optimized, and the product quality of each component has been improved, especially in the dust bag industry, in the industry, more and more The waste gas treatment requirements of the cement kiln head and kiln tail are also stricter, and large bag filter is used to treat the waste gas. The selection of the dust bag material plays a major role in the performance of the filter. The characteristics of dust and smoke emitted by cement plants are different through different technological processes:
1. High temperature, the dust discharged from the kiln tail of the rotary kiln is very high temperature, and it needs to be cooled before processing.
2. High humidity, machine shaft kiln, dryer, its moisture content is as high as 20% or more
3. High concentration, the dust concentration of the dust-containing gas it treats can reach 700-1600g/m
4. Anti-flammable and explosion-proof, such as dust-laden gas containing pulverized coal discharged from coal mills
