Several factors affecting the efficiency of the pulse bag filter
1. Can block the passage of fine dust. The warp and weft interweaving holes of the fabric should be small, while the warp and weft thread itself should be thin to increase the effective area of screening and reduce resistance.
2. The fluff of the fabric should be long and elastic so as to cover the eyelets and have a certain strength
3. In order to facilitate the cleaning of reverse airflow, the fluff of the fabric is located on the side where the dust and air are in contact.
First, the impact of filtering speed
The slower the filtration speed, the easier it is to form a primary dust layer with small particle size and large porosity, and the finer the collected dust particles. When the filtering wind speed is too high, the penetration of dust particles into the filter material will increase, leading to a decrease in filtration efficiency. . Of course, you can also suppress the phenomenon of permeation by selecting the appropriate filter material. In addition, when the filtration speed of some filter materials changes within a certain range, the dust removal efficiency is hardly affected.
Secondly, the impact of the dust layer on the filter material When the bag filter is initially operated, there is no dust layer on the new filter material. At this time, the dust collection capacity is relatively low. With the cessation of the powder filtering process, the dust layer is gradually formed and the dust is removed The efficiency is correspondingly improved. When the dust layer is completely formed, the filtration efficiency can reach more than 99%, and the fine dust particles smaller than 1 μm also have a good trapping effect.
Several factors affect the efficiency of the pulse bag filter. Three. Air leakage and resistance:
Theoretically, the dust removal efficiency of the bag type dust collector is 99%, but it has not been achieved in actual measurement. This is mainly due to the effects of air leakage and resistance. The lower the air leakage rate, the better the dust removal effect. Have a certain impact. Frequent emptying of the filter bag can reduce the resistance and improve the dust removal effect. The dust collection hood should be as close as possible to the burner, so that dust can easily enter the hood, increase the dust collection volume, and reduce fugitive emissions pollution.
4. Influence of dust bag on dust removal efficiency under different working conditions
The classification efficiency of the same dust bag under different working conditions is different, the dust removal efficiency of the clean dust bag is low, the dust removal efficiency of the dust bag after dust collection is high, and the dust removal efficiency of the dust bag after dust removal is reduced. As can be seen, The bag type dust collector plays a major role in collecting dust on the surface of the bag, which is usually called the secondary filter layer, while the bag type dust collector only plays the role of supporting the dust layer. Therefore, the dust removal intensity should be appropriate, and a certain thickness of dust layer should be retained to prevent the dust removal efficiency from decreasing.
