[0004] In the aforementioned patent, the shape of the air outlet and the inclined installation of the filter plate cause small particles in the gas to act on the bottom surface of the filter plate and bounce back by the filter plate, which can thoroughly purify the waste gas in the chemical industry production workshop and solve the problem that the current purification methods are relatively simple. However, it is difficult to clean the filter plate after filtering the waste gas, which can easily cause the filter plate to become clogged and lead to poor filtration. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waste gas purification device for industrial chemical processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an industrial chemical processing waste gas purification device, comprising a tank, a support frame fixedly installed at the bottom of the tank, an air inlet pipe fixedly installed on the circumferential surface of the tank, an air outlet pipe fixedly installed at the top of the tank, a waste outlet provided at the bottom of the tank, and a filter device provided inside the tank.

[0007] The filtration device includes a motor, a rotating shaft, a first gear, a filter plate, a rotating rod, a second gear, and a scraper. The motor is fixedly installed on the circumferential surface of the tank. The rotating shaft is fixedly installed at the output end of the motor. The first gear is fixedly installed at the end of the rotating shaft away from the output end of the motor. The filter plate is fixedly installed on the inner wall of the tank. The rotating rod rotates through the filter plate. The second gear is fixedly installed at the bottom of the rotating rod. The scraper is fixedly installed on the circumferential surface of the rotating rod. The motor drives the rotating shaft to start rotating. The rotation of the rotating shaft drives the first gear to start rotating. The rotation of the first gear drives the second gear to start rotating. The rotation of the second gear drives the rotating rod to start rotating. The rotation of the rotating rod drives the scraper to start rotating. The scraper rotates to clean the filter plate.

[0008] The tank is equipped with a pushing device to promote gas flow and a rotating device to increase the contact between gas and liquid. The pushing device increases the flow speed of the exhaust gas, and the rotating device ensures that the exhaust gas and the filtered liquid are in full contact.

[0009] According to the above technical solution, gear one meshes with gear two, and the scraper contacts the filter plate. The meshing ensures that gear one can drive gear two to rotate when it rotates, and the contact ensures that the scraper can clean the filter plate when it rotates.

[0010] According to the above technical solution, the pushing device includes a first protrusion plate, a fixed frame, a first elastic telescopic rod, a top plate, a connecting rod, a second protrusion plate, a partition plate, an accumulation block, and a rubber valve. The first protrusion plate is fixedly installed on the circumferential surface of the rotating rod, the fixed frame is fixedly installed on the inner wall of the tank, the first elastic telescopic rod is fixedly installed on the top of the fixed frame, the top plate is fixedly installed on the movable end of the first elastic telescopic rod, the connecting rod is fixedly installed on the bottom of the top plate, the second protrusion plate is fixedly installed on the bottom of the connecting rod, the partition plate is fixedly installed on the inner wall of the tank, the accumulation block is fixedly installed on the bottom of the partition plate, and the rubber valve is fixedly installed inside the partition plate. When the rotating shaft rotates, the first protrusion plate rotates, which in turn pushes the second protrusion plate to move up and down. The movement of the second protrusion plate causes the connecting rod to move, which in turn causes the top plate to move. The top plate moves and contacts the accumulation block, and under their mutual cooperation, the waste gas inside is pressurized.

[0011] According to the above technical solution, the pushing device further includes an elastic telescopic rod II and a contact plate. The elastic telescopic rod II is fixedly installed on the top of the filter plate, and the contact plate is fixedly installed on the movable end of the elastic telescopic rod II. When the protrusion plate I rotates, it no longer pushes the protrusion plate II. At this time, the top plate begins to move downward and reset under the action of the movable end of the elastic telescopic rod I. The movement of the top plate drives the connecting rod to move downward. The moving connecting rod contacts and pushes the contact plate to move downward. The moving contact plate squeezes the movable end of the elastic telescopic rod II.

[0012] According to the above technical solution, the first protrusion plate is in contact with the second protrusion plate, and the connecting rod is in contact with the contact plate. The contact ensures that the first protrusion plate can drive the second protrusion plate to move when rotating, and the contact ensures that the contact plate can reduce vibration when the connecting rod moves.

[0013] According to the above technical solution, the rotating device includes a slide rod, a fixed plate, a third gear, a linkage rod, a fourth gear, a fixed rod, and a rotating plate. The slide rod is fixedly installed on the top of the second protrusion plate, the fixed plate is fixedly installed on the top of the slide rod, the third gear is rotatably installed on the bottom of the partition plate, one end of the linkage rod is rotatably installed on the top of the fixed plate, and the other end of the linkage rod is rotatably installed on the bottom of the third gear. The fourth gear is rotatably installed on the bottom of the partition plate, the fixed rod is fixedly installed on the top of the fourth gear, and the rotating plate is fixedly installed on the circumferential surface of the fixed rod. When the second protrusion plate moves upward, it drives the slide rod to move upward. The movement of the slide rod drives the fixed plate to move upward. The movement of the fixed plate drives the linkage rod to move upward. The upward movement of the linkage rod pushes the third gear to rotate. The rotation of the third gear drives the fourth gear to rotate. The rotation of the fourth gear drives the fixed rod to rotate. The rotation of the fixed rod drives the rotating plate to rotate.

[0014] According to the above technical solution, the rotating device further includes an elastic telescopic rod three and an arc-shaped plate. The elastic telescopic rod three is fixedly installed on the inner wall of the tank, and the arc-shaped plate is fixedly installed on the movable end of the elastic telescopic rod three. When the rotating plate rotates, it contacts and pushes the arc-shaped plate to start moving. The moving arc-shaped plate squeezes the movable end of the elastic telescopic rod three. As the rotating plate continues to rotate, the rotating plate disengages from the arc-shaped plate. Subsequently, the arc-shaped plate begins to move and reset under the action of the movable end of the elastic telescopic rod three. The moving arc-shaped plate contacts the top of the rubber valve.

[0015] According to the above technical solution, gear three meshes with gear four, and the arc-shaped plate contacts the rubber valve. The meshing ensures that gear three rotates while driving gear four to rotate, and the contact ensures that the arc-shaped plate can clean the rubber valve when it moves.

[0016] This invention provides a waste gas purification device for industrial chemical processing. It has the following beneficial effects:

[0017] (1) The invention can effectively capture particulate matter such as dust and smoke in the exhaust gas through the filter plate, preventing it from entering the subsequent treatment unit or being directly discharged into the atmosphere. At the same time, the pre-removal of particulate matter through the filter plate can reduce the pollution and wear on the subsequent purification equipment, extend the service life of the equipment, and clean the filter plate by rotating the scraper to remove the particulate matter accumulated on the surface of the filter plate, prevent the filter plate from clogging, maintain its high-efficiency filtration capacity, thereby improving the overall filtration efficiency, reducing the downtime of equipment maintenance, and improving the continuous operation capability of the system. At the same time, in the treatment of exhaust gas with high dust concentration, the scraper can frequently clean the filter plate to prevent the rapid accumulation of particulate matter and ensure the normal operation of the system under high load.

[0018] (2) In this invention, the top plate moves and contacts the accumulation block, and the waste gas inside is pressurized under their mutual cooperation, so that it passes through the rubber valve faster. By squeezing the waste gas, the flow speed of the waste gas can be increased, so that it passes through the rubber valve more quickly and enters the next purification unit, thereby improving the treatment efficiency of the entire purification device. At the same time, accelerating the flow of waste gas can reduce the residence time of waste gas in the purification unit, avoid the accumulation of pollutants caused by retention, and thus improve the purification effect.

[0019] (3) The invention can effectively absorb and buffer the vibration during equipment operation by means of the cooperation between the contact plate and the elastic telescopic rod II, prevent the equipment from shaking or tilting due to vibration, ensure stable operation of the equipment, and at the same time reduce the fluctuation of exhaust gas flow caused by vibration, ensure that the exhaust gas is evenly distributed in the purification unit, thereby improving the purification efficiency.

[0020] (4) The invention enables the waste gas and the filtrate to come into full contact through the rotation of the rotating plate, thereby increasing the contact area and time between the waste gas and the filtrate, allowing the pollutants in the waste gas to be more fully absorbed or reacted by the filtrate, thus improving the purification efficiency. At the same time, the rotation of the rotating plate can promote the mass transfer process between the waste gas and the filtrate, allowing the pollutants to be transferred from the gas phase to the liquid phase more quickly, thus improving the purification speed. By moving the arc plate to contact the top of the rubber valve, the impurities that may accumulate on the top of the rubber valve can be scraped off, preventing impurities from clogging the rubber valve and causing the waste gas to not flow smoothly. At the same time, it can also prevent the excessive accumulation of impurities from weakening the filtration effect of the device. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 One embodiment of the present invention is: an industrial chemical processing waste gas purification device, including a tank 1, a support frame 2 fixedly installed at the bottom of the tank 1, an air inlet pipe 3 fixedly installed on the circumferential surface of the tank 1, an air outlet pipe 4 fixedly installed at the top of the tank 1, a waste port 5 provided at the bottom of the tank 1, and a filter device provided inside the tank 1.

[0032] The filtration device includes a motor 6, a rotating shaft 7, a first gear 8, a filter plate 9, a rotating rod 10, a second gear 11, and a scraper 12. The motor 6 is fixedly installed on the circumferential surface of the tank 1, the rotating shaft 7 is fixedly installed on the output end of the motor 6, the first gear 8 is fixedly installed on the end of the rotating shaft 7 away from the output end of the motor 6, the filter plate 9 is fixedly installed on the inner wall of the tank 1, the rotating rod 10 rotates through the filter plate 9, the second gear 11 is fixedly installed at the bottom of the rotating rod 10, and the scraper 12 is fixedly installed on the circumferential surface of the rotating rod 10. The scraper 12 cleans the filter plate 9 by rotating, scraping off the particles accumulated on the surface of the filter plate 9, preventing the filter plate 9 from clogging, maintaining its high-efficiency filtration capacity, thereby improving the overall filtration efficiency, reducing equipment downtime for maintenance, and improving the continuous operation capability of the system. At the same time, in the treatment of exhaust gas with high dust concentration, the scraper 12 can frequently clean the filter plate 9 to prevent the rapid accumulation of particles and ensure that the system operates normally under high load.

[0033] Gear 8 meshes with gear 11, and scraper 12 contacts filter plate 9. The meshing ensures that gear 8 can drive gear 11 to rotate when it rotates, and the contact ensures that scraper 12 can clean filter plate 9 when it rotates.

[0034] In this embodiment, the following steps are taken before operation: First, the operator checks the working status of the purification device. After confirming that the device is functioning correctly and without any other problems, the inlet pipe 3 is opened to introduce chemical waste gas into the tank 1. After entering the tank 1, the waste gas passes through various purification devices to remove all harmful substances before exiting the tank 1 through the outlet pipe 4. Upon entering the tank 1, the waste gas first contacts the filter plate 9. The filter plate 9 effectively captures particulate matter such as dust and smoke in the waste gas, preventing it from entering subsequent treatment units or being directly emitted into the atmosphere. Simultaneously, the pre-removal of particulate matter by the filter plate 9 reduces pollution and wear on subsequent purification equipment, extending the equipment's service life. After the gas is introduced into tank 1, the operator starts motor 6, which drives shaft 7 to rotate. The rotation of shaft 7 drives gear 8 to rotate, which in turn drives gear 11 to rotate. Gear 11 drives rotating rod 10 to rotate, which in turn drives scraper 12 to rotate. Scraper 12 cleans filter plate 9, removing particles accumulated on its surface to prevent clogging and maintain its high-efficiency filtration capacity. This improves overall filtration efficiency, reduces downtime for equipment maintenance, and enhances the system's continuous operation. In the treatment of high-dust-concentration exhaust gas, scraper 12 can frequently clean filter plate 9 to prevent rapid particle accumulation and ensure normal system operation under high load.

[0035] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the tank 1 is provided with a pushing device for promoting gas flow and a rotating device for increasing the contact between gas and liquid. The pushing device increases the flow speed of the exhaust gas, and the rotating device ensures that the exhaust gas and the filtered liquid are in full contact.

[0036] The driving device includes a first protrusion plate 131, a fixing frame 132, a first elastic telescopic rod 133, a top plate 134, a connecting rod 135, a second protrusion plate 136, a partition plate 137, an accumulation block 138, and a rubber valve 139. The first protrusion plate 131 is fixedly installed on the circumferential surface of the rotating rod 10. The fixing frame 132 is fixedly installed on the inner wall of the tank 1. The first elastic telescopic rod 133 is fixedly installed on the top of the fixing frame 132. The top plate 134 is fixedly installed on the movable end of the first elastic telescopic rod 133. The connecting rod 135 is fixedly installed on the bottom of the top plate 134. The second protrusion plate 136 is fixedly installed on the bottom of the connecting rod 135. The partition plate 137 is fixedly installed on the bottom of the connecting rod 135. Installed on the inner wall of tank 1, the accumulation block 138 is fixedly installed at the bottom of the partition plate 137, and the rubber valve 139 is fixedly installed inside the partition plate 137. The top plate 134 moves and contacts the accumulation block 138. Under their mutual cooperation, the waste gas inside is pressurized and accelerated to pass through the rubber valve 139. By squeezing the waste gas, the flow speed of the waste gas can be increased, so that it can pass through the rubber valve 139 more quickly and enter the next purification unit, thereby improving the treatment efficiency of the entire purification device. At the same time, accelerating the flow of waste gas can reduce the residence time of waste gas in the purification unit, avoid the accumulation of pollutants due to retention, and thus improve the purification effect.

[0037] The driving device also includes a second elastic telescopic rod 1310 and a contact plate 1311. The second elastic telescopic rod 1310 is fixedly installed on the top of the filter plate 9, and the contact plate 1311 is fixedly installed on the movable end of the second elastic telescopic rod 1310. Through the cooperation between the contact plate 1311 and the second elastic telescopic rod 1310, the vibration during equipment operation can be effectively absorbed and buffered, preventing the equipment from shaking or tilting due to vibration, ensuring stable operation of the equipment, and reducing the fluctuation of exhaust gas flow caused by vibration, ensuring that the exhaust gas is evenly distributed in the purification unit, thereby improving the purification efficiency.

[0038] The first protrusion plate 131 contacts the second protrusion plate 136, and the connecting rod 135 contacts the contact plate 1311. The contact ensures that the first protrusion plate 131 can drive the second protrusion plate 136 to move when rotating, and the contact ensures that the contact plate 1311 can reduce vibration when the connecting rod 135 moves.

[0039] The rotating device includes a slide rod 141, a fixed plate 142, a third gear 143, a linkage rod 144, a fourth gear 145, a fixed rod 146, and a rotating plate 147. The slide rod 141 is fixedly installed on the top of the second protrusion plate 136, the fixed plate 142 is fixedly installed on the top of the slide rod 141, the third gear 143 is rotatably installed on the bottom of the partition plate 137, one end of the linkage rod 144 is rotatably installed on the top of the fixed plate 142, and the other end of the linkage rod 144 is rotatably installed on the bottom of the third gear 143. The fourth gear 145 is rotatably installed on the partition plate 137. At the bottom of the partition plate 137, the fixing rod 146 is fixedly installed on the top of the gear four 145, and the rotating plate 147 is fixedly installed on the circumferential surface of the fixing rod 146. The rotation of the rotating plate 147 allows the exhaust gas to come into full contact with the filtrate, increasing the contact area and time between the exhaust gas and the filtrate, so that the pollutants in the exhaust gas are more fully absorbed or reacted by the filtrate, thereby improving the purification efficiency. At the same time, the rotation of the rotating plate 147 can promote the mass transfer process between the exhaust gas and the filtrate, so that the pollutants can be transferred from the gas phase to the liquid phase more quickly, thereby improving the purification speed.

[0040] The rotating device also includes an elastic telescopic rod 148 and an arc plate 149. The elastic telescopic rod 148 is fixedly installed on the inner wall of the tank 1, and the arc plate 149 is fixedly installed on the movable end of the elastic telescopic rod 148. The arc plate 149 moves to contact the top of the rubber valve 139, scraping away any impurities that may accumulate on the top of the rubber valve 139, preventing impurities from clogging the rubber valve 139 and causing poor exhaust gas flow. At the same time, it can also prevent excessive accumulation of impurities from weakening the filtration effect of the device.

[0041] Gear 3 143 meshes with gear 4 145, and arc plate 149 contacts rubber valve 139. The meshing ensures that gear 3 143 rotates while driving gear 4 145 to rotate, and the contact ensures that arc plate 149 can clean rubber valve 139 when it moves.

[0042] In this embodiment, during operation: The rotating shaft 7 drives the first protrusion plate 131 to rotate simultaneously. The rotation of the first protrusion plate 131 pushes the second protrusion plate 136 to move up and down. The movement of the second protrusion plate 136 drives the connecting rod 135 to move, which in turn drives the top plate 134 to move. The top plate 134, in contact with the accumulation block 138, pressurizes the waste gas inside, accelerating its passage through the rubber valve 139. By compressing the waste gas, the flow rate of the waste gas is increased, allowing it to pass through the rubber valve 139 more quickly and enter the next purification unit, thereby improving the overall processing efficiency of the purification device. Simultaneously, accelerating the waste gas flow reduces the residence time of the waste gas in the purification unit, preventing pollutant accumulation due to stagnation, thus improving the purification efficiency. As the convex plate 131 rotates, it stops pushing the convex plate 136. At this time, the top plate 134 begins to move downward and reset under the action of the movable end of the elastic telescopic rod 133. The movement of the top plate 134 drives the connecting rod 135 to move downward. The connecting rod 135 moves and contacts and pushes the contact plate 1311 to move downward. The contact plate 1311 moves and squeezes the movable end of the elastic telescopic rod 1310. With the cooperation of the contact plate 1311 and the elastic telescopic rod 1310, the vibration during equipment operation can be effectively absorbed and buffered, preventing the equipment from shaking or tilting due to vibration, ensuring stable operation of the equipment. At the same time, it can reduce the fluctuation of exhaust gas flow caused by vibration, ensuring that the exhaust gas is evenly distributed in the purification unit, thereby improving the purification efficiency.

[0043] As the second protrusion plate 136 begins to move upward, it drives the slide rod 141 to move upward. The movement of the slide rod 141 drives the fixed plate 142 to move upward, which in turn drives the linkage rod 144 to move upward. The upward movement of the linkage rod 144 pushes the gear 143 to rotate, which in turn drives the gear 145 to rotate. The rotation of the gear 145 drives the fixed rod 146 to rotate, which in turn drives the rotating plate 147 to rotate. The rotation of the rotating plate 147 ensures full contact between the exhaust gas and the filtrate, increasing the contact area and time between the exhaust gas and the filtrate, allowing the pollutants in the exhaust gas to be more fully absorbed or reacted by the filtrate, thereby improving the purification efficiency. At the same time, the rotating plate 147... The rotation of the rotating plate 147 promotes the mass transfer process between the waste gas and the filtrate, allowing pollutants to transfer from the gas phase to the liquid phase more quickly, thus improving the purification speed. As the rotating plate 147 rotates, it contacts and pushes the arc plate 149 to begin moving. The arc plate 149 moves and squeezes the movable end of the elastic telescopic rod 148. As the rotating plate 147 continues to rotate, it disengages from the arc plate 149. Subsequently, under the action of the movable end of the elastic telescopic rod 148, the arc plate 149 begins to move and reset. The arc plate 149 moves and contacts the top of the rubber valve 139, scraping away any impurities that may have accumulated on the top of the rubber valve 139. This prevents impurities from clogging the rubber valve 139 and causing poor waste gas flow, while also preventing excessive accumulation of impurities that could weaken the filtration effect of the device.

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