Wet dust collector is a device that allows dust containing gas to come into close contact with liquid, and uses the inertial collision and other effects of droplets and dust particles to capture dust particles or increase particle size. A filter type dust collector is a device that separates and captures dust containing gases through filter materials. Among them, bag filters using fiber fabrics as filter media are widely used in the treatment of industrial exhaust gases. When choosing a dust collector, various factors must be comprehensively considered, such as dust removal efficiency, pressure loss, initial investment, maintenance management, etc. Now let's discuss the advantages and disadvantages of each dust collector. With the increasingly stringent atmospheric emission standards, bag filters will receive more and more attention due to their advantages of small particle size and high dust removal efficiency. Bag filter is a type of dust collector that utilizes the filtering effect of fabrics such as cotton, wool, fiberglass, and synthetic fibers for dust removal.

The dusty flue gas enters the bag filter from the entrance, and under the action of inertial force, the dust particles in the flue gas will collide with the filter fibers of the dust collector, resulting in some dust particles being intercepted; Smaller particles are mainly affected by the Brownian motion of gas, and compared to the path of gas molecules undergoing Brownian motion, the gaps between fibers are much smaller, causing fine dust particles to be trapped; When a large amount of dust particles accumulate on the fibers of the filter bag, a filter cake (or filter bed) is formed, which in turn utilizes the aforementioned screening and filtering mechanisms to capture finer dust particles. Dust particles are trapped in the ash hopper, while clean gas reaches the clean gas side through the filter cloth; After the dust particles have settled to a certain extent, they are removed from the filter cloth by pneumatic or mechanical methods, collected, and transported away. During the operation of the dust collector equipment, it will adsorb the activated carbon powder contained in the air and firmly trap the smoke and dust from incineration on the surface of the filter bag, achieving the purpose of filtering the smoke and dust. But many waste incineration workers do not regularly maintain their dust removal equipment, resulting in a significant reduction in the dust removal efficiency of the dust collector equipment. In the environmental protection industry, the application of dust collector equipment has become increasingly mature, and many production enterprises have begun to realize the importance of using dust collector equipment. We should also pay more attention when using it, carefully read the instructions, and use it correctly. Sprains or fractures should also be examined and treated. Inspect the insulation layer and check whether the grounding wires of each part are complete or corroded. If necessary, re weld to ensure good grounding. Measure the grounding resistance value. Check for air leakage or dust accumulation at the interface pipes and connections with the inlet and outlet smoke boxes of the electrostatic precipitator, and promptly address any issues found.
