Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a spray device for waste gas treatment. Background Technology

[0002] In the field of industrial waste gas treatment, spray systems are core equipment for removing pollutants such as particulate matter and acidic gases from waste gases. These systems atomize the absorbent liquid into fine droplets that come into full contact with the waste gas, utilizing physical absorption or chemical reaction principles to achieve efficient pollutant removal. They are widely used in waste gas purification systems in industries such as chemical, power, and metallurgy, and are of great significance for improving air quality and reducing environmental pollution risks.

[0003] However, existing waste gas treatment spraying technologies have significant shortcomings. Traditional methods often use atomizers or atomizing nozzles to spray directly onto the waste gas outlet. The contact area between the small water droplets generated by atomization and the dust particles in the waste gas is limited, resulting in poor mixing and low particulate matter capture efficiency. At the same time, when treating high-temperature waste gas, the spray water is easily heated and evaporated quickly, causing a large waste of water resources. This increases operating costs and fails to meet the environmental protection requirements of sustainable development. Therefore, there is an urgent need to develop new spraying technologies that are highly efficient in mixing and save water and energy. Utility Model Content

[0028] Please see Figures 1 to 4A spray device for treating waste gas includes a treatment tank 1. A waste gas pipe 2 is fixedly connected to the lower surface of the treatment tank 1. One end of the waste gas pipe 2 is fixedly connected to an annular diffuser pipe 3. A nozzle 4 is fixedly connected to the upper surface of the treatment tank 1, with the upper end of the nozzle 4 penetrating the inner bottom wall of the treatment tank 1. Several nozzles 4 are arranged in a uniform annular array. A water pump 5 is fixedly connected to the lower end of the treatment tank 1. A drive module housing 6 is fixedly connected to the inner bottom wall of the treatment tank 1. An inlet pipe 7 is fixedly connected to the input end of the water pump 5, and the output end of the water pump 5... A motor 8 is fixedly connected to the lower surface of the processing tank 1 and to the interior of the drive module housing 6. An inner rotating shaft 9 is fixedly connected to the output end of the motor 8. A first bevel gear 10 is fixedly connected to the outer surface of the inner rotating shaft 9 inside the outer rotating cylinder 12. A second bevel gear 11 is rotatably connected to the inner side wall of the outer rotating cylinder 12. A vent plate 13 is fixedly connected to the lower end of the outer rotating cylinder 12. A third bevel gear 14 is fixedly connected to the lower surface of the vent plate 13. The first bevel gear 10 and the second bevel gear 11 are connected in a transmission manner. The bevel gear 11 is connected to the third bevel gear 14 for transmission. The inner wall of the drive module housing 6 is rotatably connected to the outer rotating cylinder 12. The outer surface of the inner rotating shaft 9 is fixedly connected to the fourth bevel gear 15. The end of the mixing rod 16 located inside the outer rotating cylinder 12 is fixedly connected to the fifth bevel gear 17. The fourth bevel gear 15 and the fifth bevel gear 17 are connected for transmission. Several mixing rods 16 are arranged in a circular array and evenly distributed. Several ellipsoidal hollow stirring nets 18 are arranged in a rectangular array and evenly distributed. The inner wall of the outer rotating cylinder 12... A mixing rod 16 is rotatably connected. The interior of the mixing rod 16 is hollow. One end of the mixing rod 16 is connected to the interior of the outer rotating cylinder 12. The water supply end of the atomizing nozzle 19 is connected to the mixing rod 16. The interior of the treatment tank 1 is filled with activated carbon particles. An ellipsoidal hollow stirring net 18 is fixedly connected to the outer surface of the mixing rod 16. An atomizing nozzle 19 is fixedly connected to the inner side wall of the ellipsoidal hollow stirring net 18. The upper end of the outer rotating cylinder 12 is rotatably connected to the outer surface of the inner rotating shaft 9. The upper end of the inner rotating shaft 9 is rotatably connected to the middle of the limiting frame 20.

[0029] Specifically, the motor 8 at the bottom of the treatment tank 1 drives the inner rotating shaft 9 to rotate. The first bevel gear 10 on the outer surface of the inner rotating shaft 9 meshes with the second bevel gear 11 inside the outer rotating cylinder 12. The second bevel gear 11 simultaneously drives the third bevel gear 14 under the vent plate 13, forming the inner rotating shaft 9 and the outer rotating cylinder 12 rotating in opposite directions. The fourth bevel gear 15 on the inner rotating shaft 9 meshes with the fifth bevel gear 17 at the end of the mixing rod 16. The outer surface of the mixing rod 16 is fixed with an ellipsoidal hollow stirring mesh 18, and the atomizing nozzle 19 inside is connected to the water supply end of the water pump 5. When the motor 8 drives the inner rotating shaft 9 to rotate clockwise, the first bevel gear 10 drives the outer rotating cylinder 12 to rotate counterclockwise through the second bevel gear 11. At the same time, the fourth bevel gear 15 drives the mixing rod 16 to rotate clockwise along its own axis, forming a compound motion of "revolution + rotation". The water pump 5 sprays water through the drive module housing 6, outer rotating cylinder 12, and mixing rod 16 to atomize water vapor from the atomizing nozzle 19. When the ellipsoidal hollow stirring net 18 rotates, it disturbs the exhaust gas and activated carbon particles, increasing the contact area between the atomized water vapor and the particles, thus improving efficiency compared to the traditional spraying method.

[0030] Please see Figure 1 , Figure 2 and Figure 5 A funnel cover 25 is fixedly connected to the upper end of the treatment tank 1. A limit frame 20 is fixedly connected to the inner wall of the funnel cover 25. A hinge plate 21 is fixedly connected to the upper end of the inner rotating shaft 9. A connecting rod 22 is fixedly connected to the upper end of the hinge plate 21. A scraper 23 is fixedly connected to the outer surface of the connecting rod 22. A pressure roller 24 is rotatably connected to the upper surface of the hinge plate 21. A discharge pipe 26 is fixedly connected to the upper end of the funnel cover 25. A sponge block 27 is provided on the inner wall of the discharge pipe 26. An electric butterfly valve 28 is provided at the upper end of the discharge pipe 26. An overflow pipe 29 is provided in the middle of the outer surface of the treatment tank 1. A sewage pipe 30 is provided on the lower surface of the treatment tank 1. One end of the overflow pipe 29 and one end of the sewage pipe 30 are connected.

[0031] Specifically, the upper end of the inner rotating shaft 9 is connected to the connecting rod 22 via the hinge plate 21. The outer surface of the connecting rod 22 is fixed with a scraper 23, and the upper surface is rotatably connected to the pressure roller 24. A sponge block 27 is provided on the inner side wall of the discharge pipe 26. When the inner rotating shaft 9 rotates, the pressure roller 24 periodically squeezes the sponge block 27, and the scraper 23 cleans the surface of the pressure roller 24. The overflow pipe 29 in the middle of the treatment tank 1 is connected to the bottom sewage pipe 30. The water vapor carried during the waste gas treatment process enters the discharge pipe 26 through the funnel cover 25 and is absorbed and liquefied by the sponge block 27. When the inner rotating shaft 9 rotates, the pressure roller 24 applies periodic squeezing force to the sponge block 27, squeezing the liquid water back into the treatment tank 1. The scraper 23 removes residual water droplets from the surface of the pressure roller 24, improving the recovery efficiency. At the same time, the overflow pipe 29 and the sewage pipe 30 automatically discharge impurities to ensure the cleanliness of the circulating water.

[0032] In summary, when the entire equipment is in use: connect the exhaust gas pipe 2 to the exhaust gas emission equipment, and send the exhaust gas into the annular diffuser pipe 3. Then, spray it evenly into the interior of the treatment tank 1 through the nozzle 4. Connect the water supply pipe to the water inlet pipe 7. When the water pump 5 is working, pump the water pump 5 into the drive module housing 6. Then, from the inside of the drive module housing 6, through the vent plate 13, it enters the interior of the outer rotating cylinder 12. Through the outer rotating cylinder 12, it enters the mixing rod 16. Then, it is atomized and sprayed out from the atomizing nozzle 19 in the ellipsoidal hollow mixing net 18. When the motor 8 is working, it drives the inner rotating shaft 9 to rotate. Through the transmission action of the first bevel gear 10, the second bevel gear 11, and the third bevel gear 14, when the inner rotating shaft 9 rotates forward, the outer rotating cylinder 12 will rotate in the opposite direction. Then, the inner rotating shaft 9 and the outer rotating cylinder 12 form a differential speed. When the outer rotating cylinder 12 rotates, it drives the mixing rod 16 to rotate along the center line of the inner rotating shaft 9. At this time, through the setting of the fourth bevel gear 15 and the mixing rod 16, it drives the mixing rod 16 to rotate. The rod 16 rotates along its own centerline, thereby driving the ellipsoidal hollow stirring mesh 18 to rotate in all directions and at multiple angles. During the rotation, it will agitate the activated carbon particles in the treatment tank 1. When the exhaust gas passes through the gaps in the activated carbon particles, it will be atomized by the atomizing nozzle 19 while being agitated in all directions. This will effectively improve the mixing effect of the atomized water vapor and the particles in the exhaust gas, and improve the absorption of dust particles. During the exhaust gas treatment process, some water vapor will be carried away, and the water vapor will be discharged upward from the discharge pipe 26. When it passes through the sponge block 27, the water vapor will be absorbed and liquefied by the sponge block 27. When the inner rotating shaft 9 rotates, it will drive the hinge plate 21, connecting rod 22, scraper 23 and pressure roller 24 to rotate. At this time, the two pressure rollers 24 squeeze the sponge block 27 during its rotation, thereby squeezing the water vapor absorbed by the sponge block 27 into liquid water and returning it. The scraper 23 can scrape the outer surface of the two pressure rollers 24 to improve the return efficiency of the water.
