Description

Technical Field

[0001] This invention relates to the field of air pollution control technology, and in particular to a flue gas dust removal device for air pollution prevention and control. Background Technology

[0002] Traditional flue gas dust removal technology typically involves directly passing flue gas through a filter to remove dust. While this method can remove particulate matter to some extent, the removal is not thorough enough. Some smaller particles can pass through the filter and enter the atmosphere, causing pollution. Furthermore, flue gas also contains volatile organic pollutants and acidic gaseous pollutants. Simple filtration and dust removal often cannot completely clean and purify these pollutants, thus causing air pollution. Therefore, we propose a flue gas dust removal device for air pollution control to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that traditional flue gas dust removal typically uses filter screens to remove particulate matter from flue gas. This dust removal method can only remove large particles, and small particles and polluting gases are usually difficult to remove, which can easily cause air pollution. Therefore, this invention proposes a flue gas dust removal device for air pollution control.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flue gas dust removal device for air pollution control includes a housing with openings at both the upper and lower ends. The housing is funnel-shaped, with the upper opening larger than the lower opening. A top plate is fixedly mounted at the upper opening of the housing, and the top plate is fixedly mounted at the upper opening of the housing via two connecting rods. A second conical block is fixedly mounted on the lower wall of the top plate, and a first conical block is fixedly connected to the lower end of the second conical block. The inclination angle of the second conical block is much smaller than that of the first conical block, and the outer wall of the second conical block is provided with friction textures. Spiral plates are fixedly arranged circumferentially on the outer walls of the conical block and the second conical block. The spiral plates extend outward to the inner wall of the shell. An air inlet pipe is fixedly arranged at the lower end of the shell, corresponding to the starting end of the spiral plate. Two support plates are symmetrically fixedly arranged on the side wall of the shell. A base is fixedly arranged on the lower wall of each support plate. A dust collection box is fixedly arranged at the lower opening of the shell. The dust collection box is fixedly arranged at the lower opening of the shell through a connecting mechanism. An adsorption ring is fixedly arranged between the top plate and the inner wall of the shell. A blocking mechanism corresponding to the adsorption ring is provided on the shell.

[0005] Preferably, the connecting mechanism includes two locking blocks. Two telescopic grooves corresponding to the locking blocks are symmetrically opened on the inner wall of the lower opening of the housing. The two locking blocks are slidably disposed in the two telescopic grooves, and both locking blocks are connected to the inner wall of the telescopic grooves by a first spring. Two locking slots corresponding to the locking blocks are symmetrically opened on the upper outer wall of the dust collection box. The side wall of the two locking blocks near the opening of the housing is inclined. Each of the two locking blocks is provided with a corresponding pulling mechanism.

[0006] Preferably, the pulling mechanism includes two pull rods, which are respectively fixedly mounted on the side wall of the two blocks near the first spring, and both pull rods are slidably mounted through the side wall of the housing. A pull handle is fixedly mounted on the side wall of the two pull rods away from the blocks.

[0007] Preferably, the blocking mechanism includes two blocks, and two symmetrically arranged storage slots corresponding to the blocks are provided on the upper inner wall of the housing. The two blocks are slidably arranged in the two storage slots respectively, and the two blocks are connected to the inner walls of the two storage slots respectively by a second spring. The housing is provided with a pop-out mechanism corresponding to the adsorption ring.

[0008] Preferably, the pop-out mechanism includes two fixed plates, which are symmetrically fixed on the side wall of the top plate. A third spring is fixedly installed on each of the two fixed plates. The suction ring presses against the two third springs. A lever is fixedly installed on the side wall of each of the two blocks. The two levers slide through the upper wall of the housing. The upper wall of the housing has two symmetrically opened strip-shaped slots corresponding to the levers.

[0009] Preferably, the adsorption ring adopts a honeycomb multilayer structure, and is formed by mixing activated carbon and alkaline adsorption materials inside.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the air inlet pipe 4 to correspond to the starting end of the spiral plate 10, the flue gas is directly transported to the spiral plate 10. Then, through the spiral acceleration of the spiral plate 10, the flue gas is centrifuged. Larger particles are thrown onto the inner wall of the shell 1 by centrifugation and slide down the inclined inner wall of the shell 1 into the dust collection box 2, thereby achieving the separation of large particles. By setting two conical blocks with different inclinations, the second conical block 11 on the upper side has a lower inclination and the first conical block 9 has a higher inclination, so that the flue gas is first accelerated and then decelerated during the spiral ascent from the lower side to the upper side. By setting friction textures on the side wall of the second conical block 11, friction will occur when the flue gas reaches the second conical block 11 at the upper end. While decelerating, the small particles in the flue gas are charged by friction. The honeycomb structure and diatomaceous earth in the adsorption ring 5 can complete the adsorption of charged small particles. The activated carbon and alkali in the adsorption ring 5 The adsorbent adsorbs acidic gases and volatile organic pollutants in the flue gas, thus completing the multi-stage treatment of the flue gas and avoiding pollution to the atmosphere caused by flue gas emissions. The cooperation between the locking block 14 and the locking slot enables the dust collection box 2 to be installed and fixed at the lower opening of the housing 1, allowing large particulate pollutants to fall directly into the dust collection box 2 for collection after centrifugal separation. The locking block 14 is controlled by the pull rod 17. Pulling the pull rod 17 will cause the locking block 14 to slide out of the locking slot, thereby releasing the restriction and fixation of the dust collection box 2, making it easy to quickly remove the dust collection box 2 from the housing 1 for cleaning. The blocking block 6 is used to block and fix the adsorption ring 5. The blocking block 6 is controlled by the lever 7. Moving the lever 7 will cause the blocking block 6 to be moved into the storage slot 19, thereby releasing the obstruction of the adsorption ring 5. Under the action of the third spring 22, the adsorption ring 5 is pushed upward, allowing for quick removal and replacement of the adsorption ring 5, ensuring the adsorption effect of the adsorption ring 5.

The upper opening of the housing 1 is larger than the lower opening 21. A top plate 12 is fixedly installed at the upper opening of the housing 1 via two connecting rods 23. A second conical block 11 is fixedly installed on the lower wall of the top plate 12. A first conical block 9 is fixedly connected to the lower end of the second conical block 11. The inclination of the second conical block 11 is much smaller than that of the first conical block 9. Friction textures are provided on the outer wall of the second conical block 11. Spiral plates 10 are circumferentially fixed to the outer walls of the first conical block 9 and the second conical block 11, extending outwards close to the housing. The inner wall of housing 1 is configured such that an air inlet pipe 4 is fixedly installed at the lower end of housing 1, corresponding to the starting end of spiral plate 10. Two support plates 3 are symmetrically fixedly installed on the side wall of housing 1, and a base 13 is fixedly installed on the lower wall of each support plate 3. A dust collection box 2 is fixedly installed at the lower opening of housing 1. The dust collection box 2 is fixedly installed at the lower opening 21 of housing 1 by a connecting mechanism, which includes two locking blocks 14. Two telescopic grooves 15 corresponding to the locking blocks 14 are symmetrically opened on the inner wall of the lower opening 21 of housing 1. The two locking blocks 14 are slidably installed in the two telescopic grooves 15, and both locking blocks 14 are connected to the inner wall of the telescopic grooves 15 by a first spring 16. Two telescopic grooves corresponding to the locking blocks 14 are symmetrically opened on the upper outer wall of the dust collection box 2. The slots corresponding to block 14 are provided. The side walls of the two blocks 14 near the opening of the housing 1 are inclined. Each block 14 is provided with a corresponding pulling mechanism, which includes two pull rods 17. The two pull rods 17 are respectively fixedly installed on the side walls of the two blocks 14 near the first spring 16, and both pull rods 17 slide through the side walls of the housing 1. Each pull rod 17 is fixedly installed on the side wall away from the block 14. An adsorption ring 5 is fixedly installed between the top plate 12 and the inner wall of the housing 1. The housing 1 is provided with a blocking mechanism corresponding to the adsorption ring 5. The blocking mechanism includes two blocks 6. Two storage slots 19 corresponding to the blocks 6 are symmetrically opened on the upper inner wall of the housing 1. The two blocks 6 are respectively slidably installed on the two... Within each storage slot 19, two stops 6 are connected to the inner walls of the two storage slots 19 respectively via second springs 20. The housing 1 is equipped with a pop-out mechanism corresponding to the adsorption ring 5. The pop-out mechanism includes two fixed plates 8, symmetrically fixed on the side walls of the top plate 12, and each fixed plate 8 is fixedly equipped with a third spring 22. The adsorption ring 5 presses against the two third springs 22. Each of the two stops 6 has a lever 7 fixedly installed on its side wall, and both levers 7 slide through the upper wall of the housing 1. The upper wall of the housing 1 has two symmetrically opened strip-shaped slots corresponding to the levers 7. The adsorption ring 5 adopts a honeycomb multi-layer structure, with activated carbon and alkaline adsorption materials mixed and molded inside. An air inlet pipe 4 is provided, corresponding to the starting end of the spiral plate 10.The flue gas is directly conveyed to the spiral plate 10, and then centrifuged by the spiral of the spiral plate 10. Larger particles are thrown onto the inner wall of the shell 1 by centrifugation and slide down the inclined inner wall of the shell 1 into the dust collection box 2, thus achieving the separation of large particles. By setting two conical blocks with different inclinations, the second conical block 11 on the upper side has a lower inclination and the first conical block 9 has a higher inclination. During the spiral ascent of the flue gas from the bottom to the top, it is accelerated and then decelerated. By setting friction texture on the side wall of the second conical block 11, friction will occur when the flue gas reaches the upper second conical block 11. While decelerating, the small particles in the flue gas are charged by friction. The honeycomb structure and diatomaceous earth in the adsorption ring 5 can complete the adsorption of charged small particles. The activated carbon and alkaline adsorbent in the adsorption ring 5 can adsorb acidic gases and volatile organic compounds in the flue gas. The system adsorbs pollutants to complete multi-stage treatment of flue gas, thus avoiding air pollution caused by flue gas emissions. The locking block 14, in conjunction with the slot, secures the dust collection box 2 at the lower opening of the housing 1, allowing large particulate pollutants to fall directly into the dust collection box 2 after centrifugal separation. A pull rod 17 controls the locking block 14; pulling the rod 17 slides the block out of the slot, releasing the dust collection box 2 and facilitating its quick removal from the housing 1 for cleaning. A stop block 6 blocks and fixes the adsorption ring 5. A lever 7 controls the stop block 6; moving the lever 7 retracts the stop block 6 into the collection slot 19, releasing the obstruction of the adsorption ring 5. The adsorption ring 5 is then pushed upwards by the third spring 22, allowing for quick removal and replacement, ensuring the adsorption effect of the adsorption ring 5.

[0015] In this invention, during the flue gas dust removal process, the flue gas is first directly conveyed to the spiral plate 10 through the inlet pipe 4. Then, the spiral plate 10 accelerates the flue gas, achieving centrifugal force. Larger particles are thrown onto the inner wall of the housing 1 by centrifugal force and slide down the inclined inner wall of the housing 1 into the dust collection box 2, thus achieving the separation of large particles. By setting two conical blocks with different inclinations, the second conical block 11 on the upper side has a lower inclination and the first conical block 9 has a higher inclination, so that the flue gas is first accelerated and then decelerated during the spiral ascent from the bottom to the top. Friction grooves are provided on the sidewalls of the two conical blocks 11. When the flue gas reaches the upper second conical block 11, friction occurs, which slows down the flue gas and causes small particles in the flue gas to become charged through friction. The honeycomb structure and diatomaceous earth in the adsorption ring 5 can then adsorb the charged small particles. The activated carbon and alkaline adsorbent in the adsorption ring 5 will adsorb the acidic gases and volatile organic pollutants in the flue gas, thereby completing the multi-stage treatment of the flue gas. This process sequentially completes the separation of large particulate pollutants, the cleaning of small particulate pollutants, and the adsorption of pollutant gases, effectively avoiding the pollution of the atmosphere caused by flue gas emissions.
