Problems solved by technology

[0005] However, the surface pore diameter of the filter material is small, and coarse dust, medium dust, and fine dust are all blocked on the surface of the filter material to form "surface filtration", which virtually increases the air permeability resistance of the filter material and reduces the filtration speed of the filter material. , thus affecting the effect and efficiency of high temperature flue gas and dust purification
