Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collector accessories, in particular to a bag dust collector wind shielding structure device for waste gas in paper pulp production. Background Art

[0002] The main toxic and harmful gases emitted from paper mill waste gas will directly affect the air quality of the local surrounding environment and pose a threat to the health of local residents. Once the concentration of toxic and harmful gases is too high, it will also endanger the lives of paper workers. Bag dust collector is a type of dust collector. It is mainly used in some large delivery rooms, especially those factories with a lot of dust. It relies on woven or felt filter cloth as filter material. When dust-laden gas passes through the filter bag, the dust is retained on the surface of the filter bag, and dry air is discharged through the gaps between the filter bag fibers, thereby achieving the purpose of separating dust-laden gas from dust.

[0003] At present, a Chinese patent with announcement number CN210964308U discloses a bag dust collector wind shield device, including a bottom filter, which is fixedly installed on the inner wall of the ash hopper. The beneficial effect is: when this device is installed, the bottom filter is installed on the inner wall of the ash hopper at the air inlet on the ash hopper, and the threaded rod is inserted and arranged on the inner wall of the ash hopper, so that the rotary handle is arranged on the outside of the ash hopper, and the bearing on the outside of the inner wall of the ash hopper is used to limit the movement of the threaded rod, so that it cannot be displaced while keeping rotating. When in use, according to the wind force at the air inlet, the threaded rod is rotated by the rotary handle, so that the mobile filter can move freely on the threaded rod, thereby changing the sum of the areas of the mobile filter and the bottom filter, increasing the wind shielding area, and the large particles of impurities contained in the exhaust gas in the air move obliquely downward under the action of the bottom filter and the mobile filter, and the large particles of impurities are filtered in advance, which can reduce the consumption of internal components of the bag dust collector and increase the service life of the dust collector.

[0004] However, most of the existing windshield structure devices of bag dust collectors for waste gas from pulp production are not equipped with a pre-filtration structure during use. This is because the waste gas from pulp production may contain large impurities or harder particles. When the impurity particles impact the surface of the windshield structure for a long time, the wear of the windshield structure is easily accelerated. In addition, most windshield structures are not equipped with a secondary windshield structure, and the windshield efficiency of the windshield structure is limited, which is inconvenient for users to use.
