Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically a multi-stage adsorption purification device for industrial waste gas treatment. Background Technology

[0002] Factory exhaust gas refers to the total amount of gaseous pollutants emitted into the atmosphere during factory production processes. These exhaust gases typically originate from fuel combustion, chemical reactions, and material processing. To ensure air quality, industrial exhaust gases require purification treatment.

[0003] Patent CN219186378U discloses a high-efficiency waste gas purifier for factories, including a purification chamber. A filter mechanism is located on the left side of the inner cavity of the purification chamber, a spray chamber is located on the right side of the filter mechanism, an activated carbon adsorption chamber is located on the right side of the spray chamber, a UV decomposition chamber is located on the right side of the activated carbon adsorption chamber, and an exhaust fan is located on the right side of the UV decomposition chamber. A striking mechanism is located on the top of the inner wall of the purification chamber. In use, the utility model achieves high-efficiency purification of factory waste gas through multiple stages of treatment, including filtration by the filter plate, spray absorption by the spray chamber, activated carbon adsorption in the activated carbon adsorption chamber, and photolysis by the UV lamp. The purified waste gas is harmless to the external environment. During filtration, a cylinder drives a striking rod to move back and forth via a support plate. The striking rod strikes the slot and vibrates the filter plate, preventing solid particles from clogging the filter holes and ensuring normal airflow for the purification process.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: When purifying industrial waste gas, the waste gas is first drawn into a purification chamber, then passes through filter plates to remove dust, particulate matter, and other solid particles. Following this, the waste gas undergoes further purification processes such as spraying. To prevent solid particles from clogging the filter pores and affecting gas flow, a tapping bar is installed to vibrate the filter plates and dislodge the solid particles. However, if waste gas continues to flow into the purification chamber while the filter plates are vibrating, the dislodged solid particles can easily re-adhere to the filter plate surface under the influence of the airflow, affecting the filtration effect. If the flow of waste gas is stopped for cleaning, the purification process is interrupted, reducing overall efficiency. Summary of the Invention

[0016] The beneficial effects of this invention are as follows: 1. The multi-stage adsorption purification device for industrial waste gas treatment described in this invention utilizes a segmented, covered filter plate real-time cleaning component. This component collects all solid particles adhering to the surface of the filter plate into a covered box, thereby removing solid particles from the filter plate surface and preventing the waste gas flow from being affected by solid particles clogging the filter holes. Furthermore, the entire cleaning process is carried out using a segmented covering method. When the covered box covers two rows of filter holes, the solid particles falling off in that area are isolated from the airflow and can only fall to the bottom of the covered box, preventing them from re-adhering to the filter plate surface. At the same time, the waste gas can still pass normally through the remaining uncovered filter holes, ensuring the continuity of the waste gas treatment operation. In addition, before the pressure block descends, multiple penetrating columns can be driven to simultaneously penetrate the filter holes until one end face of the penetrating column is flush with one side surface of the filter plate. At this point, the solid particles attached to the filter hole wall are pushed out. Then, the pressure block is driven to descend, and while scraping the solid particles on the surface of the filter plate, it will also scrape the solid particles attached to the end face of the penetrating column. This not only uses the penetrating column to clean the filter hole wall to further ensure the flow of exhaust gas, but also avoids the situation where solid particles attached to the end face of the penetrating column fall to the other side of the filter plate when the penetrating column is reset, and mix with the exhaust gas again, thus affecting the purification effect.

[0017] 2. The multi-stage adsorption purification device for industrial waste gas treatment described in this invention utilizes the transmission effect to maintain the components. Whenever the pressure block moves, the first and second rollers rotate, keeping the unwound portions of the first and second baffles taut. The first and second baffles cover the chute to intercept solid particles, thereby effectively preventing solid particles from entering the chute and adhering to the surface of the threaded rod, thus affecting the transmission effect and ensuring the normal displacement of the pressure block.

A stop block 22 is inserted into and slidably connected to one side of the bottom of the inner cavity of the cover box 3.

[0023] In this embodiment, as Figures 2-6 , Figures 8-12As shown, a water tank 36 is fixedly connected to one side of the outer wall of the purification box 1. A liquid pump 35 is connected and fixedly connected to the upper end of the water tank 36. A connecting pipe 34 is connected to the liquid outlet end of the liquid pump 35. The connecting pipe 34 passes through one side of the purification box 1 and is connected to multiple liquid outlet pipes 10.

[0024] An activated carbon adsorption plate 5 is fixedly connected to one side of the inner wall of the purification box 1, a UV lamp tube 7 is installed on one side of the upper end of the inner cavity of the purification box 1, and an air outlet pipe 8 is installed at one end of the purification box 1.

[0025] A threaded rod 37 is threadedly connected to one side of the transverse rod 14. Both ends of the threaded rod 37 are rotatably mounted on the purification box 1. A motor 19 is fixedly connected to one side of the outer wall of the purification box 1. The output end of the motor 19 is fixedly connected to one end of the threaded rod 37.

[0026] One end of the horizontal moving rod 14 is fixedly connected to a cylinder 16, the piston end of the cylinder 16 is fixedly connected to one side of the connecting plate 18, and one end of the horizontal moving rod 14 is fixedly connected to a cylinder 15, the piston end of the cylinder 15 is fixedly connected to one end of the cover box 3.

[0027] One side of the pressure block 24 is threadedly connected to a threaded rod 33. Both ends of the threaded rod 33 are rotatably mounted on the cover box 3. One side of the inner cavity of the cover box 3 is fixedly connected to a motor 29. The output end of the motor 29 is fixedly connected to one end of the threaded rod 33.

[0028] A threaded rod 21 is threadedly connected to one side of the stop block 22. Both ends of the threaded rod 21 are rotatably mounted on the cover box 3. A motor 23 is fixedly connected to one side of the bottom of the cover box 3. The output end of the motor 23 is fixedly connected to one end of the threaded rod 21.

[0029] Specifically, in existing technologies, when purifying industrial waste gas, the waste gas is first drawn into the purification chamber 1, then passes through the filter plate 2 to remove solid particles such as dust and particulate matter, followed by purification operations such as spraying. Furthermore, to prevent solid particles from clogging the filter holes 13 and affecting the flow of waste gas, a striking rod is provided to vibrate the filter plate 2, causing the solid particles to fall off. However, if waste gas continues to flow into the purification chamber 1 while the filter plate 2 is vibrating, the fallen solid particles can easily re-adhere to the surface of the filter plate 2 under the influence of the airflow, affecting the filtration effect. If the flow of waste gas is stopped for cleaning, the purification process is interrupted, reducing overall efficiency.

[0030] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Industrial waste gas is introduced into the purification chamber 1 through the inlet pipe 6. The filter plate 2 intercepts solid particles in the waste gas. The waste gas with solid particles removed enters the space between two partitions 4 through the connecting pipe 2 12. At this time, the liquid pump 35 draws water from the water tank 36, which is then sprayed out from the nozzle 11 through the connecting pipe 34 and the liquid outlet pipe 10 to spray the waste gas and absorb the soluble harmful gases. Then the waste gas passes through the connecting pipe 1 9 and comes into contact with the activated carbon adsorption plate 5. The activated carbon can adsorb most of the toxic and harmful gases. Then the waste gas reaches the UV lamp tube 7, which emits strong ultraviolet light to decompose the remaining toxic and harmful gases. Thus, through multi-stage adsorption purification treatment, the factory waste gas is efficiently purified. The purified waste gas is discharged through the outlet pipe 8. At this time, the waste gas is harmless to the environment.

[0031] Furthermore, during the continuous flow of exhaust gas into the purification chamber 1, the motor 19 intermittently drives the threaded rod 37 to rotate, causing the transverse rod 14 to slide intermittently on the purification chamber 1. Since the connecting plate 18 is provided with two rows of penetrating columns 17, the distance between the two rows of penetrating columns 17 is the same as the distance between the two rows of filter holes 13, and the distance between two adjacent penetrating columns 17 in the same row is the same as the distance between two adjacent filter holes 13 in the same row, when one row of penetrating columns 17 is aligned with one row of filter holes 13, the other row of penetrating columns 17 is also aligned with one row of filter holes 13. Furthermore, when the penetrating column 17 is aligned with the filter hole 13, the cylinder 15 drives the cover box 3 to move laterally, so that the cover box 3 is in contact with the surface of the filter plate 2. At this time, the two rows of filter holes 13 are covered by the cover box 3, and the pressure block 24 is located at the top of the inner cavity of the cover box 3. Then the motor 4 29 drives the threaded rod 2 33 to rotate, so that the pressure block 24 slides from top to bottom along the inner wall of the cover box 3, which can scrape off the solid particles attached to the surface of the filter plate 2. During the scraping process, the solid particles are in a closed space, so they are not affected by the airflow. When the solid particles are scraped to the bottom of the inner cavity of the cover box 3, the solid particles will come into contact with the baffle 22. The solid particles will be compressed under the cooperation of the pressure block 24 and the baffle 22, thereby reducing the volume of the solid particles and facilitating subsequent collection. Subsequently, motor 23 drives threaded rod 21 to rotate, causing stop 22 to slide and retract into one side of the inner cavity of cover box 3. Solid particles will then fall into the bottom cavity of cover box 3. Afterwards, stop 22 and pressure block 24 are reset, and cover box 3 moves away from filter plate 2 and laterally. The above operation is repeated to collect all solid particles attached to the surface of filter plate 2 into cover box 3, thereby removing solid particles from the surface of filter plate 2 and avoiding the situation where solid particles block the filter holes 13 and affect the flow of exhaust gas. In addition, the entire cleaning process is carried out in a segmented covering manner. When cover box 3 covers two rows of filter holes 13, the solid particles that fall off in this area are isolated from the airflow and can only fall into the bottom of cover box 3, and will not re-attach to the surface of filter plate 2. At the same time, exhaust gas can still pass normally through the remaining uncovered filter holes 13, ensuring the continuity of exhaust gas treatment.

[0032] Furthermore, since the two rows of penetrating columns 17 are aligned with the two rows of filter holes 13 when the cover box 3 covers the two rows of filter holes 13, the connecting plate 18 can be moved laterally by the cylinder 2 16 before the pressure block 24 descends, so that multiple penetrating columns 17 can pass through the filter holes 13 at the same time until one end face of the penetrating column 17 is flush with one side surface of the filter plate 2. At this time, the solid particles attached to the hole wall of the filter hole 13 are pushed out. Then, the pressure block 24 is driven to descend. The pressure block 24 scrapes the solid particles on the surface of the filter plate 2 and also scrapes the solid particles attached to the end face of the penetrating column 17. This can both clean the hole wall of the filter hole 13 with the penetrating column 17 to further ensure the flow of exhaust gas, and also avoid the situation where the solid particles attached to the end surface of the penetrating column 17 fall to the other side of the filter plate 2 when the penetrating column 17 is reset, and mix with the exhaust gas again, thus affecting the purification effect. In addition, operators can periodically open the door on the purification box 1 to clean the solid particles collected at the bottom of the cover box 3.

[0033] In this embodiment, as Figures 5-8 As shown, it also includes a transmission effect maintenance component; The transmission effect maintenance component includes a first roller 27 and a second roller 31 rotatably disposed at the upper and lower ends of the inner cavity of the cover box 3. A first baffle cloth 28 is wound on the first roller 27, and a second baffle cloth 30 is wound on the second roller 31. The first baffle cloth 28 passes through one side of the cover box 3 and is slidably connected to it. The second baffle cloth 30 passes through one side of the cover box 3 and is slidably connected to it. The edges of the first baffle cloth 28 and the second baffle cloth 30 are embedded in the sliding groove of the cover box 3. The ends of the first baffle cloth 28 and the second baffle cloth 30 are fixedly connected to the upper and lower end faces of the pressure block 24, respectively.

[0034] A motor 26 is fixedly connected to one side of the upper end of the inner cavity of the cover box 3, and the output end of the motor 26 is fixedly connected to the middle of the roller 27.

[0035] A motor 32 is fixedly connected to one side of the lower end of the inner cavity of the cover box 3, and the output end of the motor 32 is fixedly connected to the middle of the roller 31.

[0036] Specifically, in the above embodiment, although solid particles can be scraped by driving the pressure block 24 down along the slide groove, the movement of the pressure block 24 needs to be achieved by the motor 29 driving the threaded rod 33. Therefore, when the pressure block 24 moves, solid particles may be pushed into the slide groove. As solid particles accumulate in the slide groove, it will affect the normal displacement of the pressure block 24.

[0037] Therefore, to avoid the above problems, the working principle of this embodiment is as follows: Whenever the pressure block 24 moves, motor 3 26 drives roller 1 27 to rotate, and motor 5 32 drives roller 2 31 to rotate, keeping the unwound portions of baffle 1 28 and baffle 2 30 taut. Baffle 1 28 and baffle 2 30 cover the chute to intercept solid particles, thereby effectively preventing solid particles from entering the chute and adhering to the surface of threaded rod 2 33, thus affecting the transmission effect and ensuring the normal displacement of the pressure block 24.

[0038] Working principle: Industrial waste gas is introduced into the purification chamber 1 through the inlet pipe 6. The filter plate 2 intercepts solid particles in the waste gas. The waste gas with solid particles removed enters the space between two partitions 4 through the connecting pipe 2 12. At this time, the liquid pump 35 draws water from the water tank 36, which is then sprayed out from the nozzle 11 through the connecting pipe 34 and the liquid outlet pipe 10 to spray the waste gas and absorb the soluble harmful gases. Then the waste gas passes through the connecting pipe 1 9 and comes into contact with the activated carbon adsorption plate 5. The activated carbon can adsorb most of the toxic and harmful gases. Then the waste gas reaches the UV lamp tube 7, which emits strong ultraviolet light to decompose the remaining toxic and harmful gases. Thus, through multi-stage adsorption purification treatment, the factory waste gas is efficiently purified. The purified waste gas is discharged through the outlet pipe 8. At this time, the waste gas is harmless to the environment.

[0039] Furthermore, during the continuous flow of exhaust gas into the purification chamber 1, the motor 19 intermittently drives the threaded rod 37 to rotate, causing the transverse rod 14 to slide intermittently on the purification chamber 1. Since the connecting plate 18 is provided with two rows of penetrating columns 17, the distance between the two rows of penetrating columns 17 is the same as the distance between the two rows of filter holes 13, and the distance between two adjacent penetrating columns 17 in the same row is the same as the distance between two adjacent filter holes 13 in the same row, when one row of penetrating columns 17 is aligned with one row of filter holes 13, the other row of penetrating columns 17 is also aligned with one row of filter holes 13. Furthermore, when the penetrating column 17 is aligned with the filter hole 13, the cylinder 15 drives the cover box 3 to move laterally, so that the cover box 3 is in contact with the surface of the filter plate 2. At this time, the two rows of filter holes 13 are covered by the cover box 3, and the pressure block 24 is located at the top of the inner cavity of the cover box 3. Then the motor 4 29 drives the threaded rod 2 33 to rotate, so that the pressure block 24 slides from top to bottom along the inner wall of the cover box 3, which can scrape off the solid particles attached to the surface of the filter plate 2. During the scraping process, the solid particles are in a closed space, so they are not affected by the airflow. When the solid particles are scraped to the bottom of the inner cavity of the cover box 3, the solid particles will come into contact with the baffle 22. The solid particles will be compressed under the cooperation of the pressure block 24 and the baffle 22, thereby reducing the volume of the solid particles and facilitating subsequent collection. Subsequently, motor 23 drives threaded rod 21 to rotate, causing stop 22 to slide and retract into one side of the inner cavity of cover box 3. Solid particles will then fall into the bottom cavity of cover box 3. Afterwards, stop 22 and pressure block 24 are reset, and cover box 3 moves away from filter plate 2 and laterally. The above operation is repeated to collect all solid particles attached to the surface of filter plate 2 into cover box 3, thereby removing solid particles from the surface of filter plate 2 and avoiding the situation where solid particles block the filter holes 13 and affect the flow of exhaust gas. In addition, the entire cleaning process is carried out in a segmented covering manner. When cover box 3 covers two rows of filter holes 13, the solid particles that fall off in this area are isolated from the airflow and can only fall into the bottom of cover box 3, and will not re-attach to the surface of filter plate 2. At the same time, exhaust gas can still pass normally through the remaining uncovered filter holes 13, ensuring the continuity of exhaust gas treatment.Furthermore, since the two rows of penetrating columns 17 are aligned with the two rows of filter holes 13 when the cover box 3 covers the two rows of filter holes 13, the connecting plate 18 can be moved laterally by the cylinder 2 16 before the pressure block 24 descends, so that multiple penetrating columns 17 can pass through the filter holes 13 at the same time until one end face of the penetrating column 17 is flush with one side surface of the filter plate 2. At this time, the solid particles attached to the hole wall of the filter hole 13 are pushed out. Then, the pressure block 24 is driven to descend. The pressure block 24 scrapes the solid particles on the surface of the filter plate 2 and also scrapes the solid particles attached to the end face of the penetrating column 17. This can both clean the hole wall of the filter hole 13 with the penetrating column 17 to further ensure the flow of exhaust gas, and also avoid the situation where the solid particles attached to the end surface of the penetrating column 17 fall to the other side of the filter plate 2 when the penetrating column 17 is reset, and mix with the exhaust gas again, thus affecting the purification effect. In addition, operators can periodically open the door of the purification box 1 to clean the solid particles collected at the bottom of the cover box 3. Whenever the pressure block 24 moves, motor 3 26 drives roller 1 27 to rotate, and motor 5 32 drives roller 2 31 to rotate, keeping the unrolled portions of baffle 1 28 and baffle 2 30 taut. Baffle 1 28 and baffle 2 30 cover the slide groove to intercept solid particles, thereby effectively preventing solid particles from entering the slide groove and adhering to the surface of threaded rod 2 33, which would affect the transmission effect and ensure the normal displacement of the pressure block 24.
