Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and environmental protection, in particular to an exhaust gas dust removal and environmental protection device. Background Art

[0002] A bag filter is a dry dust filtering device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag filter, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0003] The following problems still exist in the use of this prior art: during the long-term use of the bag filter, a large amount of dust accumulates on the surface of the filter bag, affecting the dust removal efficiency. The disassembly of the filter bag is cumbersome, and manual cleaning is time-consuming and laborious. In addition, the feeding at the ash cleaning hopper is not smooth and is prone to blockage, affecting the ash cleaning efficiency. Summary of the Invention

Through the combined setting of the mounting holes, the L-shaped card slots and the blocks arranged on the surface of the U-shaped mounting ring, the disassembly and replacement of the activated carbon filter cartridge are simple and efficient. By installing an activated carbon filter element inside the exhaust pipe, the exhaust gas enters the exhaust pipe for further filtration after being dust-removed by the activated carbon filter cartridge inside the dust removal chamber, making the dust removal and filtration effect of the exhaust gas better.
