Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a dust waste gas purification treatment device and a treatment method. Background Art

[0002] As we all know, a large amount of acidic waste gas generated in industrial production processes such as chemical, food, medicine, and thermal power plants will cause serious pollution to the environment if it is directly discharged into the atmosphere. Therefore, related industrial production enterprises usually use waste gas purification equipment to purify the acidic waste gas.

[0003] A high-speed electromechanical engineering environmental dust removal device disclosed in the patent application with reference publication number CN118236776A includes a filter tube, a filter mechanism and a cleaning mechanism, the middle of the filter tube is connected with a filter mechanism for filtering dust, the middle of the filter tube is connected with a cleaning mechanism for cleaning the dust in the middle of the filter mechanism, the filter mechanism includes a dust accumulation groove, a mounting groove, a guide rail, a limit hole, a filter assembly, a collection assembly and a protection assembly, the bottom surface of the filter tube is provided with a dust accumulation groove, the front of the filter tube is provided with a mounting groove, the front and rear sides of the filter tube are symmetrically provided with guide rails, and the front of the filter tube is provided with a limit hole. The present invention provides a high-speed electromechanical engineering environmental dust removal device, by setting a filter mechanism, after dust enters the inside of the filter tube, it is coarsely filtered through the filter net, and then the smaller particles in the dust are filtered through the filter bag, and the blockage caused by dust accumulation inside the filter tube can be effectively avoided through multi-layer filtration.

[0004] In the above device, the fan is driven by exhaust gas to clean the dust on the filter. However, during the cleaning process, the dust on the filter is often in the blowing position of the exhaust gas. When cleaning, a large amount of dust is separated from the filter, but often passes through the filter due to vibration and enters the next processing step, which affects the filtration. In addition, the existing device also uses a mobile filter for scraping, but the scraped dust still stays on one side of the scraper. Therefore, when the filter is reset, the dust will re-attach to the filter, resulting in a decrease in the filtering effect of the filter and cannot be maintained in the best filtering state.

[0025] An activated carbon placement rack 202 is provided inside the primary filter frame 2 and the secondary filter frame 203. The activated carbon placement rack 202 is slidably connected to the primary filter frame 2, and multiple activated carbon blocks are placed on the activated carbon placement rack 202. A filler placement rack 601 for placing fillers is fixedly connected inside the treatment tower 6, and a spray device 602 for spraying is provided on the top of the filler placement rack 601. An intake fan 603 for exhausting air is provided on the top of the treatment tower 6.

[0026] During specific implementation, dust exhaust gas is passed into the air inlet pipe 101, the exhaust gas is filtered through the filter screen 7 inside the processing frame 1, and then passes through the ventilation pipe 102 to enter the primary filter frame 2 and the secondary filter frame 203; after being filtered through the activated carbon inside the primary filter frame 2 and the secondary filter frame 203, it enters the heat recovery device 5 through the processing tower 6 for heat recovery, wherein the internal structure of the activated carbon placement rack 202 is arranged in multiple rows and columns, and each row is staggered, and the exposed direction of the activated carbon is consistent with the entry and exit direction of the exhaust gas, so as to maintain sufficient purification of the exhaust gas, and then enter the processing tower 6 and filter through the fill inside the processing tower 6; during the filtration process, the fill is sprayed by the spray device 602 to remove the odor, thereby achieving thorough purification of the exhaust gas.

[0027] like Figures 2 to 7As shown, embodiment 2: the knocking member includes a transmission rod 802 rotatably connected to the inside of the processing frame 1, the transmission rod 802 passes through the sliding frame 8 and is movably connected to the sliding frame 8, one end of the transmission rod 802 is fixedly connected to a rotating disk 804, the outer side of the rotating disk 804 is fixedly connected to a push plate 805, a knocking plate 806 is provided on one side of the rotating disk 804, a limiting groove 807 is provided on the outer side of the knocking plate 806, the push plate 805 extends to the inside of the limiting groove 807 and is slidably connected to the knocking plate 806, and a second telescopic rod 809 is fixedly connected between the knocking plate 806 and the ventilation pipe 102.

[0028] The transmission member includes a turbofan 801 arranged on the front side of the sliding frame 8, the turbofan 801 penetrates the sliding frame 8 and is rotatably connected to the sliding frame 8, a sliding groove is provided on the outer side of the transmission rod 802, a first pulley 803 is provided on the sliding sleeve on the outer side of the transmission rod 802, a protrusion is fixedly connected inside the first pulley 803, the protrusion extends to the inside of the sliding groove of the transmission rod 802 and is slidably connected to the transmission rod 802, a second pulley 808 is fixedly connected to the outer side of the turbofan 801, and the second pulley 808 is connected to the first pulley 803 through a belt drive.

[0029] In the specific implementation, in this scheme, a sliding frame 8 is arranged inside the ventilation pipe 102, and a turbo fan 801 is arranged on the front side of the sliding frame 8. When the exhaust gas enters the ventilation pipe 102, the sliding frame 8 is pushed to slide inside the ventilation pipe 102, so that the sliding frame 8 slides inside the moving groove 103. At this time, one end of the sliding frame 8 is fixedly connected to the connecting plate 701, thereby pulling the filter screen 7 to move at the front end of the ventilation pipe 102. As the exhaust gas continues to increase, the position of the filter screen 7 in the ventilation pipe 102 is constantly changed, so that the filter screen 7 maintains the filtering effect on the exhaust gas, avoiding filtering at a single position, resulting in a decrease in the filtering effect. In the scheme, when the exhaust gas passes through the turbofan 801 at the front of the sliding frame 8, the turbofan 801 is driven to rotate. The rotation of the turbofan 801 drives the first pulley 803 to rotate respectively through the two second pulleys 808 fixedly connected on the outside. The first pulley 803 drives the transmission rod 802 to rotate through the cooperation of the protrusion and the slide groove. When the transmission rod 802 rotates, the transmission rod 802 drives the rotating disk 804 fixed at one end to rotate, and the rotating disk 804 drives the push plate 805 to rotate, and then the push plate 805 continuously drives the stopper 807 on the outside of the knocking plate 806. The movable knocking plate 806 moves horizontally to knock the filter 7 on one side of the knocking plate 806, so that the dust on the outside of the filter 7 is knocked off, and a collecting frame is set at the bottom end of the processing frame 1 to collect the dust. It is worth mentioning that when the turbofan 801 rotates fast, it means that the amount of exhaust gas entering is large, so the knocking of the knocking plate 806 will be accelerated, thereby improving the cleaning effect, so that it can automatically adjust according to the exhaust gas introduction situation, and the rotation of the turbofan 801 can disperse the exhaust gas evenly when it enters the primary filter frame 2 to avoid excessive concentration.

[0030] like Figures 6 to 10 As shown, embodiment three: the cleaning component includes a cleaning scraper 9 that fits the surface of the filter screen 7, and a transmission rack plate 901 is fixedly connected to the side of the cleaning scraper 9 away from the filter screen 7. A first telescopic rod 902 and a second spring 903 are fixedly connected between the transmission rack plate 901 and the processing frame 1, and the second spring 903 is sleeved on the outside of the first telescopic rod 902.

[0031] In specific implementation, when the filter 7 moves under the pull of the sliding frame 8, cleaning scrapers 9 are provided on both sides of the filter 7. The cleaning scrapers 9 fit the surface of the filter 7. When the filter 7 moves, the cleaning scrapers 9 will scrape off the dust on the dust surface and cooperate with the knocking piece to clean the dust filter side.

[0032] In this embodiment, the cleaning assembly also includes a rotating rod 905, and two transmission gears 906 are sleeved on the outer side of the rotating rod 905. The two transmission gears 906 are connected to the rotating rod 905 through a one-way damping bearing. Both ends of the rotating rod 905 are rotatably connected to a fixed plate 904, and the fixed plate 904 is fixedly connected to the processing frame 1.

[0033] The traction member includes a rotating rod 905 with a winding disk 907 fixedly connected to the outside, a traction rope 908 is wound and fixed to the outside of the winding disk 907, the traction rope 908 is fixedly connected to the connecting plate 701, and fixed cylinders 909 are provided on the outside of both ends of the rotating rod 905. The fixed cylinders 909 are fixedly connected to the fixed plate 904, and a torsion spring 910 is fixedly connected between the fixed cylinder 909 and the rotating rod 905.

[0034] In specific implementation, when the filter screen 7 moves with the connecting plate 701, if the cleaning scraper 9 is always in contact with the filter screen 7, the cleaning scraper 9 will scrape the dust on the front side of the cleaning scraper 9. When the filter screen 7 is reset at a later time, the dust adheres to the filter screen 7 and moves to the air inlet of the ventilation pipe 102, resulting in the filter screen 7 being unable to be thoroughly cleaned during filtering. Therefore, in this solution, a traction member is provided. When the connecting plate 701 moves to one end, the connecting plate 701 away from the air inlet of the ventilation pipe 102 pulls the winding drum 907 to rotate through the traction rope 908. The rotation of the winding drum 907 drives the rotating rod 905 fixedly connected to the outside to rotate. Since the rotating rod 905 is connected to the transmission gear 906 through a one-way damping bearing, The damping setting drives the transmission gear 906 to rotate, and the rotation of the transmission gear 906 drives the meshing transmission rack plate 901 away from the filter screen 7. The cleaning component on the other side, due to the one-way damping bearing set between the rotating rod 905 and the transmission gear 906, quickly pushes the transmission rack plate 901 through the second spring 903 on the outside of the first telescopic rod 902, so that the cleaning scraper 9 contacts the filter screen 7, and the torsion spring 910 fixedly connected between the rotating rod 905 and the fixed cylinder 909 drives the rotating rod 905 to rotate, so that the traction rope 908 is wound to the outside of the winding disk 907, so that the dust is scraped to the rear side of the cleaning scraper 9, thereby achieving the cleaning effect on the surface of the filter screen 7 and avoiding the dust from adhering to the surface of the filter screen 7 again.

[0035] like Figures 1 to 11 As shown, embodiment 4: a through groove is provided on the outer side of the cleaning scraper 9, a screw rod 1001 is arranged inside the through groove, the screw rod 1001 passes through the cleaning scraper 9 and is rotatably connected with the cleaning scraper 9, both ends of the screw rod 1001 are fixedly connected with fixed gears 1002, the outer sides of the two fixed gears 1002 are meshedly connected with fixed racks 1003, the fixed racks 1003 are fixedly connected with the ventilation pipe 102, and a plurality of cleaning plates 1004 are connected to the outer side of the screw rod 1001 through a ball nut pair, and the cleaning plates 1004 are slidably connected with the outer side of the cleaning scraper 9.

[0036] In specific implementation, when the cleaning scraper 9 is moved away from the filter screen 7 by the action of the traction member, the fixed gear 1002 is meshed and connected with the fixed rack 1003, thereby driving the fixedly connected screw rod 1001 to rotate. When the screw rod 1001 rotates, it drives multiple cleaning plates 1004 on the outside connected by the ball nut pair to move, thereby scraping off the dust on the surface of the cleaning scraper 9, thereby cleaning the dust on the cleaning scraper 9, and as the cleaning scraper 9 is reset, the cleaning plate 1004 is automatically reset to prepare for the next cleaning.

[0037] In addition, a fan 11 is fixedly connected to the top of the processing frame 1, and the air outlet end of the fan 11 is fixedly connected to the air inlet pipe 101. When the exhaust gas introduced is too small to drive the entire device, the wind force can be increased by starting the fan 11 to provide power for the device, and the flow efficiency of the exhaust gas can be adjusted, and the movement of the filter 7 can be adjusted to ensure that the position where the exhaust gas passes through the filter 7 changes, thereby maintaining the filtering state of the filter 7.

[0038] A method for purifying dust and waste gas is also provided, comprising the following steps: Step 1: When the dust exhaust gas enters the air inlet pipe 101, the exhaust gas is filtered by the filter screen 7 inside the processing frame 1, and then enters the primary filter frame 2 and the secondary filter frame 203 through the ventilation pipe 102; Step 2: After being filtered through the activated carbon inside the primary filter frame 2 and the secondary filter frame 203, it enters the heat recovery device 5 through the treatment tower 6 for heat recovery, and then enters the inside of the treatment tower 6 and is filtered through the fill soil inside the treatment tower 6; Step 3: During the filtering process, the filling soil is sprayed by the spraying device 602 to remove the odor.
