Description

Technical Field

[0001] The invention relates to the field of filtering technology, and in particular to a smoke filtering treatment device and method for a biomass burner. Background Art

[0002] When burning, biomass burners will produce a lot of dust and smoke, which contain a lot of particulate matter and harmful gases. If they are not treated, these pollutants will cause serious harm to the environment and human health. Filtering the smoke can effectively remove these harmful substances and protect the environment and human health. In the prior art, the equipment for filtering the smoke of biomass burners is usually a bag filter. Publication No. CN117443095B discloses a bag filter and an anti-corrosion coating production system including the bag filter. The problems raised in the background technology are as follows: since the filter bag is relatively long and the filter bag is air-permeable, when the gas ejected from the blowing pipe is blown to the bottom of the filter bag, the blowing force decreases significantly, the cleaning capacity of the filter bag is reduced, and the bottom of the filter bag is prone to dust blockage. At the same time, the shear temperature of the material increases during crushing. During the long-term dust removal process, the high dust temperature may cause local burning of the filter bag, thereby reducing the dust filtering effect. Publication No. CN113350909B discloses a bag dust collector, and the problem raised in its background technology is that during the use of the bag dust collector, dust easily clumps and adheres to the bag, and the dust removal effect needs to be improved by only using a pulse jet tube for dust removal.

[0003] Based on the existing technology, there are the following problems: The above application document cleans the cloth bag by arranging a cleaning device on the outside of the cloth bag and a fan inside the cloth bag. Although it can achieve a certain cleaning effect, during the cleaning process, the brush will squeeze the dust on the outer surface of the cloth bag to a certain extent, causing the dust to penetrate deeper into the cloth bag. The fan will generate suction while generating wind force. Arranging the fan inside the cloth bag is not conducive to actual cleaning use. The above application document cleans by striking the cloth bag, but a supporting mechanism for supporting the cloth bag is usually provided inside the cloth bag. During the striking process, the supporting mechanism collides with the striking mechanism, affecting actual use. In addition, affected by the supporting mechanism, the striking is insufficient, reducing the cleaning effect, and thus it is not convenient for the long-term filtering use of the cloth bag. Although the existing cloth bag cleaning mechanism can achieve a certain cleaning effect, it leaves certain cleaning dead corners, affecting the subsequent filtering use of the cloth bag. There are certain deficiencies. In order to solve the above problems, a flue gas filtration treatment device and method for a biomass burner are proposed. Summary of the invention

[0024] In a specific implementation, the inner wall of the bag 21 is supported by the support rods 241 arranged in a circular array, and the bottom of the inner wall of the bag 21 is supported by the support blocks 242, so that the bag 21 is opened, so that the smoke contacts the outer surface of the bag 21, thereby filtering the smoke in the smoke; By providing the support groove, it is convenient to place the support rod 241. When the support rod 241 is restrained by the cloth bag 21 and enters the support groove, the cloth bag 21 can be opened by the support rod 241 and the support block 242. When the support rod 241 is driven by the moving assembly 25 and moves in a direction away from the support block 242, the cloth bag 21 is opened, and the lower end of the support rod 241 is designed to be arc-shaped to avoid damage to the cloth bag 21 during opening. The interior of the support block 242 is hollow and provided with air guide holes, so that the gas can be blown to the bottom of the cloth bag 21 along the air guide holes and the support block 242, thereby reducing the dead corners for cleaning.

A second electromagnet 2534 is fixedly provided on one end of the fixing rod 2535 close to the first electromagnet 2533. The fixing groove 2532 enables the fixing shell 2531 to cooperate with the second electromagnet 2534 to limit the fixing rod 2535 from being separated from the fixing shell 2531. One end of the fixing rod 2535 located outside the fixing shell 2531 is fixedly connected to the inner side of the support rod 241.

[0026] In the specific implementation, the first electromagnet 2533 and the second electromagnet 2534 are energized, and the side where the first electromagnet 2533 and the second electromagnet 2534 are close to each other is the same pole, so as to generate repulsive force to drive the second electromagnet 2534 to move along the fixed groove 2532, thereby driving the fixed rod 2535 and the support rod 241 to move, so that the support rod 241 is separated from each other, thereby stretching the cloth bag 21 outward from the cloth bag 21, so that the gas blown out by the subsequent blowing component 23 is in contact with the smoke and dust, and the cleaning effect is improved.
