Factors affecting the efficiency of bag filter


Bag dust collectors are currently relatively mature products on the market. Manufacturers of bag dust collectors have mixed technologies. Due to the immature technology of some manufacturers, the dust removal efficiency of bag dust collectors produced by many manufacturers does not reach satisfactory results. For dust removal The system, under certain conditions, better products will be affected by some factors. According to our company's years of experience in the design and production of dust removal equipment, several factors affecting the efficiency of dust removal in the design of bag dust collectors are summarized. The factors are as follows:


Factors affecting the efficiency of the bag filter are:


Dust characteristics. The dust removal efficiency of the bag filter is directly related to the size, gravity, shape, electrostatic effect and dust concentration of the dust particles. The dust with large particles, heavy weight, irregular shape and obvious electrostatic effect has higher dust removal efficiency.


Performance of dust bag.


The performance of the filter cloth has a great influence on the dust removal efficiency and resistance. The material of the filter cloth should meet the following conditions:


1. It can block the passage of fine dust. The holes of the fabric warp and weft yarns should be smaller, while the warp and weft yarns themselves should be thinner 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 holes and have a certain strength;


3. In order to facilitate reverse air cleaning, the fluff of the fabric is located on the side where the dusty air contacts.


Factors Affecting the Efficiency of the Bag Dust Collector


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, thereby reducing the filtration efficiency. Of course, you can also overcome the phenomenon of permeation by choosing the right filter material. In addition, when the filtering wind speed changes within a certain range, the dust removal efficiency of some filter materials is hardly affected.

Fourth, the impact of the dust layer on the filter material. At the beginning of the operation of the bag filter, there is no dust layer on the new filter material. At this time, the ability to capture dust is relatively low. With the progress of the filter powder process, the dust layer is gradually formed. The dust removal efficiency is also improved accordingly. When the dust layer is completely formed, the filtration efficiency can reach more than 99%, and it has a good trapping effect on fine dust particles smaller than 1 μm.


Factors affecting the efficiency of the bag filter: air leakage and resistance:


In theory, the dust removal efficiency of the bag filter 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. The resistance has a certain effect on the dust removal effect. 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.
