The filter bag is the heart during the operation of the cloth bag dust collector. Usually the cylindrical pulse filter bag is hung vertically in the dust collector. Some large particles of dust are separated by inertial force and fall directly into the ash hopper. Dust-containing gas enters the filter area of the filter bag, and most of the dust is trapped on the outer surface of the filter bag, while clean gas enters the filter bag through the filter material. , And then discharged by the air outlet. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. At the same time, it helps to remove and redistribute the dust cake.
Dust filter bag is an efficient dust filter material, has good ventilation performance, high dust removal efficiency, and has a certain acid resistance, alkali resistance and heat resistance, the use of multilateral brushing in the weaving process, which increases the thickness of the fabric and is elastic The dust removal effect is very good, and the dust removal rate can reach 99.999%. The dust filter bag is made of polyester staple fiber or long fiber. The service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, high capacity for dust removal, and a dust removal efficiency of 98.99%.
After 30 years of development and exploration of waste incineration, the entire technological process, including the major unit equipment and local systems, has reached the foremost level. Among them, the flue gas system process is as follows:
Waste power generation: In 2017, 70% of the 359 operating waste incineration plants did not disclose monitoring data, especially dust particles (the above data)
Analysis of the current status of filter bags: PTFE membrane filter bags have become a must for waste incineration and hazardous waste disposal industry for ultra-low emission of dust particles, but there are still a series of problems
