What are the factors that cause the dust removal efficiency of bag dust collectors to decrease?

According to the research of Yite Environmental Protection Technology Group, the mechanism of dust particles penetrating the filter material, which causes the dust removal efficiency of bag dust collectors to decrease, mainly has the following three aspects: ① Straight-through. Dust particles smaller than the diameter of the pores on the surface of the filter material or dust layer penetrate the filter material and out (pores are straight-through), or penetrate through the curved pores in the filter material or dust layer (pores are not straight-through). ② Pressing out. During the filtration process, when the dust layer accumulated on the filter material gradually thickens, the pressure difference of the filter layer also increases. Under the action of the pressure difference, the bridge of the dust on the pores of the filter material may be destroyed, and the dust particles are pressed out through the pores. When the filtration is resumed after cleaning, the dust particles are pressed out through the partially damaged powder layer. ③ Pores. When the filtration wind speed of the bag dust collector is high, the dust par
