Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, in particular to a dust removal device for waste gas treatment. Background Art

[0002] With the rapid development of industry, a large amount of waste gas is inevitably generated. The waste gas contains a large amount of harmful gases such as dust particles, smoke, soot and odorous gases. If it is directly discharged to the outside, it will cause unpredictable harm to the surrounding environment. Therefore, the waste gas needs to be treated in a series of ways and can only be discharged after meeting the standards for external discharge.

[0003] Existing document CN211611968U-A dust removal device for exhaust gas treatment, including a shell, a drainage hole connected to the inside of the shell is opened at the bottom of the shell, an exhaust hole connected to the inside of the shell is opened on the left side of the shell, and an opening connected to the inside of the shell is opened at the top of the shell, and a conduit is movably connected inside the opening. Through the cooperation between the stop rod, the magnet block, the pull rod and the insertion rod, the pull rod is pulled upward so that the magnet block adsorbs the insertion rod, and then the handle is pulled so that the handle drives the outer ring to move outward through the through hole on the surface of the stop rod, thereby taking out the filter screen and the filter cloth layer for cleaning, solving the problem that the existing dust removal device for exhaust gas treatment is inconvenient to clean the dust particles after filtering in time, resulting in reduced filtering effect of the dust removal device, but it still has the following disadvantages in actual use:

[0004] 1. The above-mentioned dust removal device for exhaust gas treatment sprays water mist through a spraying mechanism to increase the weight of dust in the exhaust gas entering the shell and separate it from the gas. However, the waste water accumulated by the water mist sprayed by the spraying mechanism is discharged from the drainage hole, and long-term use will cause a large amount of water resources to be wasted;

[0005] 2. The above-mentioned dust removal device for exhaust gas treatment removes the filter screen and filter cloth through the cooperation between the blocking rod, the magnet block, the pull rod and the insertion rod. However, the magnet block will reduce its magnetism after long-term use, and the magnet block is embedded in the shell and is not easy to remove and replace, which makes it inconvenient to replace the filter screen and filter cloth after long-term use.
