The mechanism of filter dust removal in the filter bag of high-temperature dust collector is the sieve filter effect. The dust cage uses the air pressure generated by the fan to press the dusty air against the surface of the dust cage. Most of the short pile and impurities are retained on the surface of the dust cage. The filter web layer is formed, and the dust-containing air passing through the dust cage enters the second-stage filteringChina Vacuum Filter Belts suppliers device through the channels on both sides of the dust cage. The pre-separator can be seen as a type of dust cage filtration. The advantages of dust cage filtration are the combination of less auxiliary equipment, diffusion and sedimentation, direct interception, inertial collision and electrostatic adsorption. The management is simple and convenient, the filtered cotton aphid has a high recycling rate, and the filter material such as a nonwoven fabric or a foam plastic is separated from the airflow.
With the thickening of the dust layer of the filter bag of the high-temperature dust collector, the textile fiber dust collector has a dust cage filter, a filter bag filter and a packed filter bed filter dust collector. The dust layer needs to be removed regularly to ensure continuous dust removal. The textile fiber dust collector is classified according to the structure of the dust collector. The dust layer is formed in the dust or the inside of the filter material. The dust cage is a cylinder surrounded by a metal mesh. The two ends of the cylinder are open to the air passage. When the dust-laden air passes through the mesh, the fabric, and the filter layer formed by the upper layer of the powder, it is generally assembled into a dust filter device by other filtration methods. The disadvantage is that the air volume is not large, the floor space is relatively large, and the power consumption is high.
