Description
The material of dust collector bag is synthetic fiber, natural fiber or glass fiber woven cloth or felt. Sew the cloth or felt into cylinder or flat filter bag as required. According to the properties of flue gas, the suitable filter material is selected.
Overview
In general, when the flue gas temperature is lower than 120 ℃, and the filter material is required to have acid resistance and durability, polyester flannelette and polyester needle felt are often used; when dealing with high temperature flue gas (< 250 ℃), graphitized glass cloth is mainly used; in some special cases, carbon fiber, glass fiber, PPS, P84, DWD, PTFE, fluorous, basalt filter material, etc. are selected. It is very important to control the speed of flue gas passing through the filter material in the operation of bag filter. Generally, the filtration speed is 0.5-2m/min, and the efficiency of particles larger than 0.1 μM can reach more than 99%, and the resistance loss of equipment is about 980-1470pa.
