Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, specifically to a desulfurization tower with automatic cleaning function. Background Technology

[0002] Environmental protection equipment refers to mechanical products, structures, and systems manufactured and constructed by production or construction units, designed to control environmental pollution and improve environmental quality. Some people consider environmental protection equipment to be simply mechanically processed products used for environmental pollution control. Furthermore, environmental protection equipment also includes power equipment for conveying fluids containing pollutants, as well as monitoring and control instruments to ensure the normal operation of environmental pollution prevention and control facilities. Environmental governance is urgent, and we should attach greater importance to environmental protection. Environmental protection equipment should include complete sets of equipment that can be used in both industrial and household applications to control environmental pollution.

[0003] Desulfurization towers are common environmental protection equipment widely used in industrial production. Their main function is to neutralize sulfur dioxide in waste gas with alkaline solution, thereby reducing sulfur dioxide emissions and protecting the environment. However, during operation, particulate matter in the waste gas falls to the bottom of the desulfurization tower along with the alkaline solution, causing a large amount of sludge to accumulate. This reduces the circulation efficiency of the alkaline solution, further affecting the desulfurization effect of the tower. Regular cleaning of the sludge at the bottom of the desulfurization tower is necessary to ensure its normal operation and efficient desulfurization.

[0004] In view of this, we propose a desulfurization tower with automatic cleaning function. Summary of the Invention

[0005] The purpose of this invention is to provide a desulfurization tower with an automatic cleaning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a desulfurization tower with automatic cleaning function, comprising a main body, an inlet pipe fixedly connected to the top end face of the main body, an air inlet pipe fixedly connected to the side wall of the main body, a discharge port two provided at the bottom of the main body, a motor fixedly connected to the bottom end face of the main body, one end of a rotating shaft fixedly connected to the output shaft of the motor, the other end of the rotating shaft penetrating the bottom end face of the main body and sleeved with a scraper, and a filter disc fixedly connected to the side wall of the air inlet pipe.

[0007] Optionally, a rotating rod is fixedly connected to the top end face of the rotating shaft, and a bevel gear is fixedly connected to the side wall of the rotating rod. A scraping assembly is sleeved on the filter disc, and the scraping assembly includes a crossbar. The filter disc is sleeved on the crossbar, and a bevel gear is fixedly connected to the side wall of the crossbar. A second scraper is fixedly connected to the side wall of the crossbar, and a third scraper is rotatably connected to the end of the second scraper away from the crossbar. The rotation of the motor drives the rotating shaft to rotate, which in turn drives the rotating rod to rotate. The rotation of the rotating rod drives the crossbar to rotate via the bevel gear, and the rotation of the crossbar drives the second and third scrapers to rotate, thereby scraping the end face of the filter disc and cleaning the deposits on the filter disc.

[0008] Optionally, a connector is fixedly connected to the side wall of the rotating shaft, and a spring is fixedly connected to the bottom end face of the connector. The end of the spring away from the connector abuts against a scraper. The top of the connector is arc-shaped to prevent alkaline residue from remaining on the top end face of the connector. The spring, through elastic deformation, tightly abuts the scraper against the inner bottom end face of the main body, preventing wear and tear on the scraper over time, which would prevent it from adhering tightly to the inner bottom of the main body and affecting the cleaning effect on the inner bottom of the main body.

[0009] Optionally, the scraper is made of rubber, which can fit the inner bottom surface of the main body. By driving the rotating shaft and scraper to rotate through the motor, the inner bottom of the main body can be better scraped, so that the alkali solution can be collected.

[0010] Optionally, a spray assembly is fixedly connected to the top of the main body. One end of the spray assembly is fixedly connected to a liquid inlet pipe, and the other end of the spray assembly is provided with a spray head. The alkaline solution enters the spray assembly through the liquid inlet pipe, and then is pressurized and sprayed out through the spray head. This can spray the sulfur dioxide gas inside the main body, so that the sulfur dioxide reacts and neutralizes with the alkaline solution.

[0011] Optionally, scraper two and scraper three abut against the end face of the filter disc, and scraper two and scraper three scrape the end face of the filter disc to scrape off the smoke and dust filtered by the filter disc.

[0012] Optionally, one end of spring two is fixedly connected to the side wall of scraper two, and scraper three is fixedly connected to the other end of spring two. One end of spring three is fixedly connected to the side wall of scraper two, and scraper three is fixedly connected to the other end of spring three.

[0013] Optionally, the end of the crossbar furthest from the scraping assembly is sleeved on the inner wall of the main body, and the crossbar is fixedly connected to the air intake pipe through the sleeved fixing rod, which can improve the stability of the crossbar rotation and prevent the crossbar from shifting position during rotation.

[0014] Optionally, the bottom end face of the air intake pipe is provided with a discharge port 1, which is located in front of the filter disc. The width of the discharge port 1 is greater than the width of scraper 2 and scraper 3. The sediment scraped off by scraper 2 and scraper 3 can be collected by an external collection device through discharge port 1 and then subjected to harmless treatment.

[0015] Optionally, the combined length of scraper two and scraper three is greater than the radius of the filter disc. When scraper two and scraper three move directly above discharge port one, spring two contracts, straightening scraper three and sweeping the deposits on the front side of scraper two and scraper three into discharge port one. Spring three restricts the position of scraper three, preventing scraper three from sticking to scraper two. As scraper two and scraper three continue to move, the edge of discharge port one presses against scraper three, causing scraper three to retract, and the end of scraper three away from scraper two abuts against the air inlet pipe.

[0016] Compared with the prior art, the present invention provides a desulfurization tower with automatic cleaning function, which has the following beneficial effects: 1. This desulfurization tower with automatic cleaning function, in order to achieve the recycling of alkaline solution, introduces sulfur dioxide gas through the inlet pipe. As the sulfur dioxide gas passes through the filter plate, the particulate matter in the gas is filtered out, and the reduced particulate matter sulfur dioxide gas enters the main body. Alkaline solution is introduced through the inlet pipe and enters the spray assembly, then is pressurized and sprayed out through the spray heads. The spray heads spray the sulfur dioxide gas inside the main body, causing the sulfur dioxide to react and neutralize with the alkaline solution. Due to gravity, the alkaline solution falls to the inner bottom of the main body. The motor starts, driving the rotating shaft to rotate. The rotating shaft drives a scraper plate to scrape the inner bottom of the main body, scraping the alkaline solution into the discharge port. Because the particulate matter in the sulfur dioxide gas is filtered out by the filter plate, the alkaline solution deposited at the inner bottom of the main body cannot form a viscous slurry with the deposits, thus achieving the recycling of the alkaline solution and improving the desulfurization effect of the desulfurization tower.

[0017] 2. This desulfurization tower with automatic cleaning function utilizes a motor to drive a rotating shaft to improve the filtration efficiency of the filter discs. The rotating shaft in turn drives a rotating rod, which in turn drives a crossbar via a bevel gear. This crossbar then rotates scrapers two and three, which scrape the end faces of the filter discs, thus cleaning the deposits. As scrapers two and three continue to move, the edge of discharge port one presses against scraper three, causing it to retract and the end of scraper three furthest from scraper two to contact the inlet pipe. Centrifugal force helps to better dislodge the deposits scraped off by scrapers two and three, allowing them to be more effectively thrown into discharge port one, thus improving the filtration effect of the filter discs.

[0018] 3. To prevent wear and tear on the scraper blade from prolonged use, which could compromise its tight fit against the inner bottom of the main body and affect cleaning efficiency, the desulfurization tower with an automatic cleaning function uses a connector fixedly attached to the side wall of the rotating shaft. A spring is fixedly attached to the bottom end of the connector, with the end of the spring furthest from the connector abutting against the scraper blade. The top of the connector is arc-shaped to prevent alkali residue from remaining on its top surface. The spring, through elastic deformation, firmly presses the scraper blade against the inner bottom surface of the main body, preventing wear and tear from prolonged use that could compromise its tight fit and cleaning efficiency.

[0021] like Figures 1-6As shown, the present invention provides a technical solution: a desulfurization tower with automatic cleaning function, including a main body 1, a liquid inlet pipe 2 fixedly connected to the top end face of the main body 1, an air inlet pipe 3 fixedly connected to the side wall of the main body 1, a discharge port 21 provided at the bottom of the main body 1, a spray assembly 11 fixedly connected to the top of the main body 1, a liquid inlet pipe 2 fixedly connected to one end of the spray assembly 11, and a spray head 12 provided at the other end of the spray assembly 11. Alkali solution enters the spray assembly 11 through the liquid inlet pipe 2, and is then pressurized and sprayed out through the spray head 12, which can spray the sulfur dioxide gas inside the main body 1, so that the sulfur dioxide reacts and neutralizes with the alkali solution. A motor 5 is fixedly connected to the bottom end face of the main body 1. One end of a rotating shaft 6 is fixedly connected to the output shaft of the motor 5. The other end of the rotating shaft 6 passes through the bottom end face of the main body 1 and is fitted with a scraper 7. The scraper 7 is made of rubber, which can conform to the inner bottom end face of the main body 1. The motor 5 drives the rotating shaft 6 and scraper 7 to rotate, achieving better scraping of the inner bottom of the main body 1 and allowing the alkaline solution to be collected. A connector 8 is fixedly connected to the side wall of the rotating shaft 6. A spring 9 is fixedly connected to the bottom end face of the connector 8. The end of the spring 9 away from the connector 8 abuts against the scraper 7. The top of the connector 8 is arc-shaped to prevent alkaline solution residue from remaining on its top end face. The spring 9, through elastic deformation, tightly abuts the scraper 7 against the inner bottom end face of the main body 1, preventing wear and tear from prolonged use, which would prevent the scraper 7 from failing to conform tightly to the inner bottom of the main body 1 and affect the cleaning effect. A filter disc 16 is fixedly connected to the side wall of the air intake pipe 3. A rotating rod 10 is fixedly connected to the top end face of the rotating shaft 6. A bevel gear 13 is fixedly connected to the side wall of the rotating rod 10. A scraping assembly is sleeved on the filter disc 16. The scraping assembly includes a crossbar 14. The end of the crossbar 14 away from the scraping assembly is sleeved on the inner wall of the main body 1. The crossbar 14 is fixedly connected to the air intake pipe 3 through a sleeved fixing rod 15, which can improve the stability of the crossbar 14 rotation and prevent the crossbar 14 from shifting position during rotation. The filter disc 16 is sleeved on the crossbar 14. A bevel gear 13 is fixedly connected to the side wall of the crossbar 14. A scraper 2 17 is fixedly connected to the side wall of the crossbar 14. A scraper 3 18 is rotatably connected to the end of the scraper 2 17 away from the crossbar 14. The scraper 2 17 and scraper 3 18 abut against the end face of the filter disc 16 and scrape the end face of the filter disc 16, which can scrape off the smoke and dust filtered by the filter disc 16. The rotation of motor 5 drives the rotation of shaft 6, which in turn drives the rotation of rod 10. The rotation of rod 10, through bevel gear 13, drives the rotation of crossbar 14. The rotation of crossbar 14 drives scraper blades 17 and 18 to rotate, thereby scraping the end face of filter disc 16 and cleaning the deposits on it. One end of spring 19 is fixedly connected to the side wall of scraper blade 17, and scraper blade 18 is fixedly connected to the other end of spring 19. One end of spring 20 is fixedly connected to the side wall of scraper blade 17, and scraper blade 18 is fixedly connected to the other end of spring 20.The bottom end face of the air intake pipe 3 is provided with a discharge port 4, which is located in front of the filter disc 16. The width of the discharge port 4 is greater than the width of scraper 2 17 and scraper 3 18. The sediment scraped off by scraper 2 17 and scraper 3 18 can be collected by an external collection device through the discharge port 4 and then subjected to harmless treatment. The sum of the lengths of scraper 2 17 and scraper 3 18 is greater than the radius of the filter disc 16. When scraper 2 17 and scraper 3 18 move directly above the discharge port 4, spring 2 19 contracts, straightening scraper 3 18 and sweeping the sediment in front of scraper 2 17 and scraper 3 18 into the discharge port 4. Spring 3 20 restricts the position of scraper 3 18 to prevent scraper 3 18 from sticking to scraper 2 17. Scraper 2 17 and scraper 3 18 continue to move. The edge of discharge port 1 4 squeezes scraper 3 18, causing scraper 3 18 to retract. The end of scraper 3 18 away from scraper 2 17 comes into contact with air inlet pipe 3.

[0022] In one embodiment of the present invention, sulfur dioxide gas is introduced through the inlet pipe 3. As the sulfur dioxide gas passes through the filter plate 16, the particulate matter in the gas is filtered out, and the reduced particulate matter sulfur dioxide gas enters the interior of the main body 1. Alkali solution is introduced through the liquid inlet pipe 2 and enters the spray assembly 11, then is pressurized and sprayed out through the spray head 12. The spray head 12 sprays the sulfur dioxide gas inside the main body 1, causing the sulfur dioxide to react and neutralize with the alkali solution. Due to gravity, the alkali solution falls to the inner bottom of the main body 1. The motor 5 starts, driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the scraper 7 to scrape the inner bottom of the main body 1, scraping the alkali solution into the discharge port 21. Because the particulate matter in the sulfur dioxide gas is filtered by the filter plate 16, the alkali solution deposited at the inner bottom of the main body 1 cannot form a viscous slurry with the deposits. Therefore, the alkali solution can be recycled, improving the desulfurization effect of the desulfurization tower.

[0023] To improve the filtration efficiency of the filter disc 16, a rotating rod 10 is fixedly connected to the top end face of the rotating shaft 6, and a bevel gear 13 is fixedly connected to the side wall of the rotating rod 10. A scraping assembly is fitted onto the filter disc 16, and the scraping assembly includes a crossbar 14. The crossbar 14 is fitted onto the filter disc 16, and a bevel gear 13 is fixedly connected to the side wall of the crossbar 14. A scraper 2 17 is fixedly connected to the side wall of the crossbar 14, and a scraper 3 18 is rotatably connected to the end of the scraper 2 17 away from the crossbar 14. A discharge port 1 4 is provided on the bottom end face of the air inlet pipe 3. The discharge port 1 4 is located on the front side of the filter disc 16, and the width of the discharge port 1 4 is greater than the width of the scraper 2 17 and the scraper 3 18. The combined length of scraper 2 17 and scraper 3 18 is greater than the radius of filter disc 16. When scraper 2 17 and scraper 3 18 move directly above discharge port 4, spring 2 19 contracts, straightening scraper 3 18 and sweeping the deposits on the front side of scraper 2 17 and scraper 3 18 into discharge port 4. Spring 3 20 restricts the position of scraper 3 18 to prevent scraper 3 18 from sticking to scraper 2 17. Motor 5 rotates, driving shaft 6 to rotate, which in turn drives rod 10 to rotate. Rod 10 rotates, which in turn drives crossbar 14 to rotate via bevel gear 13. Crossbar 14 rotates, which in turn drives scraper 2 17 and scraper 3 18 to rotate, thereby scraping the end face of filter disc 16 and cleaning the deposits on filter disc 16. Scraper 2 17 and scraper 3 18 continue to move, and the edge of discharge port 1 4 squeezes scraper 3 18, causing scraper 3 18 to retract, and the end of scraper 3 18 away from scraper 2 17 comes into contact with the air inlet pipe 3. Centrifugal force can better throw the sediment scraped off by scraper 2 17 and scraper 3 18 into discharge port 1 4, improving the filtration effect of filter disc 16.

[0024] In addition, to prevent the scraper 7 from wearing down after prolonged use and thus failing to adhere tightly to the inner bottom of the main body 1, thereby affecting the cleaning effect on the inner bottom of the main body 1, a connector 8 is fixedly connected to the side wall of the rotating shaft 6. A spring 9 is fixedly connected to the bottom end face of the connector 8, and the end of the spring 9 away from the connector 8 abuts against the scraper 7. The top of the connector 8 is arc-shaped to prevent alkaline residue from remaining on the top end face of the connector 8. The spring 9, through elastic deformation, firmly abuts the scraper 7 against the inner bottom end face of the main body 1, preventing the scraper 7 from wearing down after prolonged use and thus failing to adhere tightly to the inner bottom of the main body 1, thereby affecting the cleaning effect on the inner bottom of the main body 1.

[0025] In this invention, during use, sulfur dioxide gas is introduced through the inlet pipe 3. As the sulfur dioxide gas passes through the filter plate 16, the particulate matter in the gas is filtered out, and the reduced particulate matter sulfur dioxide gas enters the interior of the main body 1. Alkali solution is introduced through the liquid inlet pipe 2 and enters the spray assembly 11, then is pressurized and sprayed out through the spray head 12. The spray head 12 sprays the sulfur dioxide gas inside the main body 1, causing the sulfur dioxide to react and neutralize with the alkali solution. Due to gravity, the alkali solution falls to the inner bottom of the main body 1. The motor 5 starts, driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the scraper 7 to scrape the inner bottom of the main body 1, scraping the alkali solution into the discharge port 21. Because the particulate matter in the sulfur dioxide gas is filtered by the filter plate 16, the alkali solution deposited at the inner bottom of the main body 1 cannot form a viscous slurry with the deposits. Therefore, the alkali solution can be recycled, improving the desulfurization effect of the desulfurization tower. The rotation of motor 5 drives the rotation of shaft 6, which in turn drives the rotation of rod 10. The rotation of rod 10, through bevel gear 13, drives the rotation of crossbar 14. The rotation of crossbar 14 drives scraper 17 and scraper 18 to rotate, thereby scraping the end face of filter disc 16 and cleaning the deposits on it. Scraper 17 and scraper 18 continue to move, and the edge of discharge port 4 presses against scraper 18, causing it to retract and the end of scraper 18 away from scraper 17 to contact the air inlet pipe 3. Centrifugal force allows the deposits scraped off by scraper 17 and scraper 18 to be better thrown into discharge port 4, improving the filtration effect of filter disc 16. The top of the connector 8 is arc-shaped to prevent alkaline solution from remaining on the top end face of the connector 8. The spring 9, through elastic deformation, tightly presses the scraper 7 against the inner bottom end face of the main body 1 to prevent the scraper 7 from wearing out after long-term use, thus preventing it from not being able to fit tightly against the inner bottom of the main body 1 and affecting the cleaning effect on the inner bottom of the main body 1.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
