Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and in particular to a small dust removal device and a dust removal method. Background Art

[0002] During the material transportation process in steel, cement, mining, power plants and other enterprises, the conveyor belt conveyor discharge port guide chute will generate a lot of dust. Existing dust removal technology generally uses bag-type centralized dust removal, connecting multiple dust point dust hoods through pipelines, and then performing dust removal operations over a long distance. Since the dust-containing gas needs to be transported over a long distance in the pipeline, it causes serious pressure loss and air volume loss. In order to ensure the dust removal effect, traditional designs use high wind pressure and large air volume to offset the unfavorable factors of long-distance transportation, which results in increased energy consumption of centralized bag dust removal systems and greatly increases production costs.

[0003] At the same time, due to long-distance transportation and simultaneous or switching use of multiple points, the wind speed in the pipeline cannot be stabilized within a reasonable range, which can easily cause dust accumulation in some pipelines, reduce the air volume, and finally cause pipeline blockage, thus affecting the dust removal effect. Summary of the invention

[0004] The purpose of the present invention is to provide a small dust removal device and a dust removal method, which are small in overall size and easy to assemble and disassemble, and can be conveniently installed at the dust generating point as needed, thereby reducing various disadvantages of large bag dust removal pipeline transportation.
