Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device with a cleaning structure. Background Art

[0002] Waste gas treatment mainly refers to the treatment of industrial waste gas generated in industrial sites. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc. For organic waste gas, the treatment methods mainly include activated carbon adsorption treatment, adsorption-recovery method, adsorption-catalytic combustion method, etc.

[0003] After searching, such as the Chinese patent: CN216367148U, a cleaning structure for an exhaust gas treatment filter includes a ventilation pipe and a filter, a dust sweeping assembly for sweeping dust is provided at the mounting hole at the top of the ventilation pipe, and an ash discharge assembly for discharging dust is provided directly below the ash sweeping assembly of the ventilation pipe, the outer wall of the filter is slidably connected to the inner wall of the ventilation pipe, and a shaking assembly for shaking the filter is provided on the right side of the filter; through the above method, the shaking filter reduces the possibility of dust sticking to the filter, avoids clogging of the filter, and ensures the filtering efficiency of the filter.

[0004] Although the current exhaust gas treatment device can reduce the possibility of dust sticking to the filter by shaking the filter to improve the effect of exhaust gas treatment, due to the wide variety of exhaust gases (such as industrial exhaust gas, domestic exhaust gas and traffic exhaust gas, etc.), some of the exhaust gases contain grease, especially the raw materials and products used in some industrial production processes may contain grease, solvents and other components, which may evaporate or leak during the production process, resulting in oil pollution in the exhaust gas (such as waste gas generated in the production process of industrial enterprises such as petroleum, chemical, and coatings). When treating the exhaust gas containing grease, the oil pollution will flow with the exhaust gas and gradually adhere to the filter of the exhaust gas treatment equipment. When the traditional exhaust gas treatment device cleans the filter, it uses a cleaning brush to clean the surface of the filter, which makes it difficult to clean the grease, resulting in incomplete cleaning, thereby indirectly affecting the use effect of the exhaust gas treatment equipment.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, an exhaust gas treatment device with a cleaning structure includes a pipe 1, a filter screen 2 is installed inside the pipe 1, and a spray assembly is provided on one side of the filter screen 2;

[0025] Among them, the spray assembly includes a cleaning plate 3 arranged on one side of the filter 2, and a nozzle 14 is fixedly installed on the side wall of the cleaning plate 3, and the nozzles 14 are evenly arranged. A connecting pipe 5 is fixedly connected to the top of the cleaning plate 3, and a mixing box 6 is installed at the end of the connecting pipe 5 away from the cleaning plate 3. A water pipe 7 is fixedly installed on one side of the mixing box 6, and a water pump 8 is arranged at the bottom end of the water pipe 7.

[0026] By setting the spray assembly, when it is necessary to clean the filter 2, the water pump 8 can be started by an external power supply, and the water pump 8 is connected to the external water source through the water pipe 7. When the water pump 8 is started, the external water source is discharged into the interior of the mixing box 6 through the water pipe 7, and the water source is discharged into the interior of the cleaning plate 3 through the mixing box 6. A through hole for water flow is opened in the cleaning plate 3, and the through hole is arranged corresponding to the nozzle 14, so that the water source can be discharged from the nozzle 14 and sprayed to the surface of the filter 2, and the surface of the filter 2 is sprayed and cleaned, thereby avoiding that when the exhaust gas containing grease is treated, the oil will flow with the exhaust gas and gradually adhere to the filter 2 of the exhaust gas treatment equipment. When the conventional exhaust gas treatment device cleans the filter 2, it is difficult to clean the grease, resulting in incomplete cleaning, thereby indirectly affecting the use effect of the exhaust gas treatment equipment, thereby improving the use effect of the exhaust gas treatment equipment.

[0027] Existing: CN216367148U discloses a cleaning structure for an exhaust gas treatment filter. This patent discloses the ventilation pipe, filter, dust hood, brush mounting plate and bristles proposed in the present application document. The pipe 1, filter 2, cleaning plate 3 and bristles 4 in the present application document all adopt the same technical means in the prior art, and this technical means will not be repeated here one by one.

[0028] like Figures 1 to 5 As shown, the side walls of the cleaning plate 3 are evenly installed with bristles 4, the top of the cleaning plate 3 is fixedly connected with a slider 9, a threaded rod 10 is embedded inside the slider 9, the threaded rod 10 is rotatably installed on the inner wall of the pipe 1, and a motor 11 is installed at one end of the threaded rod 10.

[0029] When the filter 2 needs to be cleaned, the motor 11 can be started by an external power supply. Since the input end of the motor 11 is electrically connected to the external power supply through a wire, and the output end of the motor 11 is fixedly connected to the threaded rod 10, the start of the motor 11 drives the rotation of the threaded rod 10, and the rotation of the threaded rod 10 drives the movement of the slider 9. The movement of the slider 9 drives the movement of the cleaning plate 3. The movement of the cleaning plate 3 drives the movement of the bristles 4, so that the bristles 4 clean the surface of the filter 2. By cooperating with the spray assembly, the cleaning effect of the filter 2 is further improved, thereby ensuring the treatment effect of the exhaust gas.

[0030] like Figures 1 to 5 As shown, a storage tank 12 is fixedly mounted on the top of the mixing box 6 , and a dust plug 13 is embedded in the top of the storage tank 12 .

[0031] A cleaning agent is provided inside the storage tank 12 , and the cleaning agent can be added to the inside of the storage tank 12 through the dust plug 13 .

[0032] like Figures 1 to 5 As shown, a baffle 20 is provided below the storage tank 12, and the baffle 20 is slidably mounted on the inner wall of the mixing box 6. A rack plate 19 is fixedly connected to one side of the baffle 20, and the bottom end of the rack plate 19 is meshedly connected to the second gear 18, and the bottom end of the second gear 18 is meshedly connected to the first gear 17. A rotating shaft 16 is fixedly mounted on the inner wall of the first gear 17, and a fan blade plate 15 is mounted at one end of the rotating shaft 16. The fan blade plate 15 is rotatably mounted inside the mixing box 6.

[0033] When the external water source is discharged into the mixing box 6 through the water pipe 7, it can drive the rotation of the impeller plate 15, and the rotation of the impeller plate 15 drives the rotation of the rotating shaft 16. The rotation of the rotating shaft 16 drives the rotation of the first gear 17. The rotation of the first gear 17 drives the rotation of the second gear 18. The rotation of the second gear 18 drives the movement of the rack plate 19. The movement of the rack plate 19 drives the movement of the baffle 20, so that the detergent inside the storage tank 12 falls into the inside of the mixing box 6, and is finally discharged from the nozzle 14 through the connecting pipe 5, spraying the surface of the filter 2, further improving the cleaning effect of the filter 2.

[0034] like Figures 1 to 5 As shown, the fan blade 15 is arranged below the baffle 20.

[0035] When the cleaning agent enters the mixing box 6, the rotation of the blade plate 15 can drive the water and the cleaning agent to be stirred, so that the two are mixed, so that the blade plate 15 can not only serve as a power, but also play a stirring effect on the cleaning agent and water.

[0036] like Figures 1 to 5 As shown, the first gear 17 is rotatably mounted on the inner wall of the mixing box 6, and the first gear 17 is configured as a sector gear.

[0037] When the first gear 17 rotates to mesh with the second gear 18, the second gear 18 is driven to rotate, so that the baffle 20 is opened, and cooperates with the spring 21 to achieve the effect of intermittent discharge of the cleaning agent.

[0038] like Figures 1 to 5 As shown, a spring 21 is provided on one side of the baffle 20 , and the spring 21 is installed on the inner wall of the mixing box 6 .

[0039] The two ends of the spring 21 are fixedly connected to the baffle 20 and the mixing box 6 respectively. When the baffle 20 moves, the spring 21 is deformed to store elastic potential energy, and the elastic potential energy is released by the spring 21 to drive the baffle 20 to reset, so that the baffle 20 can slide back and forth, playing the role of intermittent feeding, which is conducive to the full mixing of the cleaning agent and water.

[0040] The utility model provides an exhaust gas treatment device with a cleaning structure, and the specific working principle is as follows:

[0041] During the waste gas treatment, the water pump 8 can be started by an external power supply, and the water pump 8 is connected to an external water source through a water pipe 7. The external water source is discharged into the mixing box 6 through the water pipe 7, driving the rotation of the impeller plate 15, and the rotation of the impeller plate 15 drives the rotation of the rotating shaft 16, and the rotation of the rotating shaft 16 drives the rotation of the first gear 17, and the rotation of the first gear 17 drives the rotation of the second gear 18, and the rotation of the second gear 18 drives the movement of the rack plate 19, and the movement of the rack plate 19 drives the movement of the baffle 20, so that the detergent inside the storage tank 12 falls into the inside of the mixing box 6, and is mixed with water through the rotation of the impeller plate 15, and finally discharged from the nozzle 14 through the connecting pipe 5, and sprays the surface of the filter screen 2;

[0042] At the same time, the motor 11 can be started by an external power supply, the start of the motor 11 drives the rotation of the threaded rod 10, the rotation of the threaded rod 10 drives the movement of the slider 9, the movement of the slider 9 drives the movement of the cleaning plate 3, the movement of the cleaning plate 3 drives the movement of the bristles 4 and the nozzle 14, so that the bristles 4 clean the surface of the filter screen 2;

[0043] Finally, the impurities and sewage are discharged through the dust collecting hood installed at the bottom end of the pipeline 1.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
