Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, and more specifically, to a spray-type reaction tower for industrial waste gas treatment. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. Industrial waste gas contains a variety of compounds, and if it is directly emitted into the air, it will cause air pollution. In order to reduce the harm caused by industrial waste gas, spray towers can be used to treat industrial waste gas.

[0003] In existing technologies, such as patent number CN202123063447.8, entitled "An Industrial Waste Gas Treatment Spray Device," the waste gas mainly uses a guide plate to increase its flow path within the outer casing. A water pump then pumps water from a storage tank to a connecting pipe, which in turn delivers it to the spray pipe. The water is atomized and sprayed onto the waste gas through the spray nozzles, thus increasing the flow distance and improving the treatment effect. However, this method has some problems. Since it primarily treats the waste gas with water, and the waste gas contains various compound impurities, water alone cannot separate these compounds, resulting in poor treatment. Replacing the water with a solution is also problematic because the numerous compounds cannot be separated by a single solution. Mixing multiple solutions can negatively impact the solution's effectiveness, making it inconvenient to use. Summary of the Invention

[0004] To address the above deficiencies, this invention provides a spray-type reaction tower for industrial waste gas treatment, thereby solving the problems mentioned above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spray-type reaction tower for industrial waste gas treatment includes a tower body, an inlet pipe installed at the upper end of the tower body, an exhaust pipe installed at the lower end of the tower body, multiple holding plates installed inside the tower body, the holding plates dividing the tower body into multiple treatment spaces, adjacent treatment spaces being connected by gas guide pipes, the outlet end of the gas guide pipe being located at the upper end of the treatment space, the inlet end of the gas guide pipe being located at the upper end of the treatment space, partitions installed within each treatment space, a sorting spray mechanism installed on the tower body, a feeding mechanism provided on one side of the sorting spray mechanism, and an impurity cleaning mechanism provided within each treatment space.

[0007] The classification spraying mechanism includes multiple solution tanks located on one side of the processing space. These tanks are fixedly installed on the tower body. The solution tanks on different sides of the processing space contain different solutions. A suction pump is installed on one side of each solution tank. Multiple spray nozzles are installed at the upper end of the processing space. The outlet of the suction pump is connected to the inlet of each spray nozzle via a multi-port pipe. A liquid outlet pipe is installed at the lower end of each solution tank, with its outlet connected to the inlet of the suction pump. A drain pipe is installed on one side of the lower end of the processing space, with its outlet extending into the upper part of the solution tank.

[0008] The feeding mechanism includes a feeding box located on one side of the upper end of the solution tank, which is fixedly installed on the tower body. A first push-button valve is installed on one side of the lower end of the feeding box, and a first feed pipe is installed at the outlet end of the first push-button valve, extending into the upper part of the solution tank. A liquid solute tank is installed on one side of the upper end of the feeding box, and a metering tank is installed at the lower end of the liquid solute tank. A second push-button valve is installed at the lower end of the metering tank, and a second feed pipe is installed at the outlet end of the second push-button valve, extending into the feeding box. A third push-button valve is installed at the upper end of the metering tank. The system includes a push-button valve, a third feed pipe at the bottom of the liquid solute tank (the outlet of which connects to the inlet of a third push-button valve), an vent valve at the top of the feed tank, and a fourth push-button valve at the bottom of the feed tank (the inlet of which connects to a water pipe). A multi-stage electric telescopic rod is mounted on the solution tank, with a moving rod at its telescopic end. Both ends of the moving rod have pressing platforms that can be moved to one side of the first, second, third, and fourth push-button valves and opened them.

[0009] The impurity cleaning mechanism includes inlet and outlet located on both sides of the lower end of the processing space. An impurity holding box is placed at the lower end of the processing space. Multiple square openings are opened at the lower end of the impurity holding box. A rotating plate is hinged to the square opening. Multiple push wheels are provided on one side of the inlet and outlet. The push wheels are fixedly installed on the tower body. Collection boxes are provided on both sides of the processing space. The collection boxes are fixedly installed on the tower body. The impurity holding box can be moved above the collection box. A connecting rod is installed at one end of the moving rod. One end of the connecting rod is connected to one end of the impurity holding box.

[0010] Furthermore, a lifting plate is provided on one side of the partition, lifting blocks are installed at both ends of the lifting plate, a guide slide is provided on one side of the lifting block, the guide slide is fixedly installed on the partition, one end of the lifting block extends into the guide slide, and a floating block is installed on the lower surface of the lifting plate.

[0011] Furthermore, a protective net is installed at one end of the drain pipe within the processing space, and a first round hole is opened on one side of the upper end of the impurity holding box. A second round hole is opened on the first round hole, and the first round hole and the second round hole are located on the side of the processing space near the protective net.

[0012] Furthermore, a filter screen is installed at the upper end of the collection box, and a waste liquid pipe is installed at the lower end of the collection box. The outlet end of the waste liquid pipe is connected to a sewage treatment device on the ground.

[0013] Furthermore, the filter screen includes a square frame fixedly installed at the upper end of the collection box. A filter plate is hinged to the inner side of the square frame via a hinge. The filter plate has multiple filter holes. A take-up motor is provided on one side of the upper end of the collection box. A take-up wheel is installed on the rotating end of the take-up motor. The take-up wheel and one end of the filter plate are connected by a connecting wire. A protective shell is installed on the outside of the take-up motor. The protective shell is installed on one side of the upper end of the collection box. A square hole is provided on the protective shell to facilitate the entry and exit of the connecting wire. A fixed pulley is installed at the lower end of the square hole. A vibrator is installed on the filter plate.

[0014] Furthermore, a discharge port is installed on one side of the upper end of the collection box. The discharge port is located on one side of the filter plate and is connected to a discharge channel.

[0015] Furthermore, a stirrer is installed on the feeding box.

[0016] Furthermore, guide grooves are provided on both sides of the lower end of the processing space, and guide blocks are installed on both sides of the impurity holding box, with one end of the guide block extending into the guide groove.

[0017] Furthermore, sealing gaskets are installed at the inlet and outlet, sealing platforms are installed on both sides of the impurity holding box, and a partition platform is installed in the middle of the impurity holding box.

[0018] The beneficial effects of this invention are as follows: The tower body is divided into multiple processing spaces by a holding plate, and each processing space has a solution tank on one side holding different solutions. This allows each processing space to treat only one or several compounds in the waste gas, resulting in better treatment efficiency. Furthermore, the solutions can be recycled, reducing costs. After a period of use, the solutions react with the compounds, beginning to affect the treatment effect. At this time, a large amount of impurities accumulate at the lower end of the processing space. The extension and retraction of a multi-stage electric telescopic rod pushes the impurity holding tank, opening the inlet and outlet, allowing the solution in the processing space to be discharged along with the impurities. This prevents the accumulation of excessive impurities within the tower body and facilitates solution replacement. During the extension and retraction of the multi-stage electric telescopic rod, the solution in the feeding tank is discharged into the solution tank by controlling the opening and closing of several push-button valves, and solvent and solute are added back to the feeding tank. This facilitates automatic solution addition and ease of use.

[0019] After the impurity holding tank is pushed out, gravity causes the used solution and impurities to fall into the collection tank. The filter screen inside the collection tank can intercept the impurities, thus achieving solid-liquid separation and facilitating the separate processing of the solution and impurities.

[0020] Installing a lifting plate on the partition allows the liquid level to rise when impurities at the lower end of the treatment space increase. This pushes the lifting plate upwards, increasing the distance between the lifting plate and the liquid surface, preventing waste gas from being blocked, and ensuring the waste gas treatment process.

[0035] The innovation of this application lies in the structural design of the classified spraying mechanism, combined with the attached... Figure 1 Appendix Figure 4 and attached Figure 8The classification spraying mechanism includes multiple solution tanks 7 located on one side of the treatment space. The solution tanks 7 are fixedly installed on the tower body 1. Different solutions are contained in the solution tanks 7 on different sides of the treatment space. A suction pump 8 is installed on one side of each solution tank 7. Multiple spray nozzles 9 are installed at the upper end of the treatment space. The outlet of the suction pump 8 is connected to the inlet of the spray nozzle 9 via a multi-port pipe 10. A liquid outlet pipe 11 is installed at the lower end of each solution tank 7, and its outlet is connected to the inlet of the suction pump 8. A drain pipe 12 is installed on one side of the lower end of the treatment space, with its outlet extending into the upper part of the solution tank 7. By setting up multiple solution tanks 7 and placing different solutions in each tank, compounds in the waste gas can be classified and neutralized, resulting in better treatment effects. Furthermore, the solutions can be recycled, reducing costs.

[0036] The innovation of this application lies in the structural design of the feeding mechanism, combined with the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 8 and attached Figure 9 The feeding mechanism includes a feeding box 13 located on one side of the upper end of the solution tank 7. The feeding box 13 is fixedly installed on the tower body 1. A first push-button valve 14 is installed on one side of the lower end of the feeding box 13. A first guide pipe 15 is installed at the outlet end of the first push-button valve 14, and the outlet end of the first guide pipe 15 extends into the upper part of the solution tank 7. A liquid solute tank 16 is installed on one side of the upper end of the feeding box 13. A metering tank 17 is installed at the lower end of the liquid solute tank 16. A second push-button valve 18 is installed at the lower end of the metering tank 17. A second guide pipe 19 is installed at the outlet end of the second push-button valve 18, and the outlet end of the second guide pipe 19 extends into the feeding box 13.

A third guide pipe 21 is installed at the lower end of the liquid solute tank 16, and the outlet end of the third guide pipe 21 is connected to the third push-button valve 17.

A moving rod 25 is installed at the telescopic end of the multi-stage electric telescopic rod 24. Pressing platforms 26 are installed at both ends of the moving rod 25. The pressing platforms 26 can be moved to one side of the first push-button valve 14, the second push-button valve 18, the third push-button valve 20, and the fourth push-button valve 23 and opened thereon. By extending and retracting the multi-stage electric telescopic rod 24, the first push-button valve 14, the second push-button valve 18, the third push-button valve 20, and the fourth push-button valve 23 can be opened and closed respectively, facilitating solution replacement in the solution tank 7.

[0037] The inventive point of this application lies in the structural design of the impurity cleaning mechanism, combined with the attached... Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 8 The impurity cleaning mechanism includes inlet and outlet 27 located on both sides of the lower end of the processing space. An impurity holding box 28 is placed at the lower end of the processing space. Multiple square openings 29 are opened at the lower end of the impurity holding box 28. A rotating plate 30 is hinged to the square opening 29. Multiple push wheels 31 are provided on one side of the inlet and outlet 27. The push wheels 31 are fixedly installed on the tower body 1. Collection boxes 32 are provided on both sides of the processing space. The collection boxes 32 are fixedly installed on the tower body 1. The impurity holding box 28 can be moved above the collection box 32. A connecting rod 33 is installed at one end of the moving rod 25. One end of the connecting rod 33 is connected to one end of the impurity holding box 28. By moving the impurity holding box 28, the inlet and outlet 27 can be opened easily, and the solution and impurities can be cleaned.

[0038] In this device, the electrical equipment is controlled by an external controller. Under normal conditions, the multi-stage electric telescopic rod 24 is in its longest extended state. One end of the impurity holding box 28 is located at the lower end of the processing space, and the other end is located above a collection box 32. The sealing gasket 58 is respectively attached to the sealing platform 59 and the partition platform 60 to seal the inlet and outlet 27, preventing the solution and waste gas from leaking out. An appropriate amount of solution is added to the solution tank 7 and the feeding tank 13. The first button valve 14, the second button valve 18, the third button valve 20, and the fourth button valve 23 are all in the closed state.

[0039] Waste gas enters the uppermost processing space within the tower body 1 through the inlet pipe 2, flows between processing spaces via the guide pipe 5, and is finally discharged through the exhaust pipe 3. The baffle 6 divides the processing space in two, allowing the waste gas to enter from above, bypass the baffle 6, and exit from the top, increasing the flow time. Under normal conditions, the floating block 37 rests on the receiving plate 4, maintaining a distance between the lifting plate 34 and the receiving plate 4 to facilitate waste gas passage. While the waste gas flows within the tower body 1, the suction pump 8 draws the solution from the solution tank 7 through the outlet pipe 11 and discharges it through the multi-port pipe 10 onto multiple spray nozzles 9. After atomization by the spray nozzles 9, the waste gas is treated, and impurities and solution fall to the lower end of the processing space. The solution falling into the processing space is discharged into the solution tank 7 through the drain pipe 12. Impurities are intercepted by the protective net 38, facilitating solution circulation and reuse, thus reducing the cost of waste gas treatment.

[0040] After a period of use, the solution has reacted with impurities in the waste gas multiple times, reducing its treatment efficiency. Furthermore, a certain amount of impurities has accumulated at the lower end of the impurity collection tank 28, necessitating solution replacement and cleaning of the impurities. When a large amount of impurities is present at the lower end of the impurity collection tank 28, the liquid level rises. This causes the float 37 to be buoyed and move upwards, pushing the lifting plate 34 upwards. The lifting block 35 and guide slide 36 ensure the direction of movement of the lifting plate 34. Consequently, after the liquid level rises at the lower end of the treatment space, the distance between the lifting plate 34 and the collection plate 4 increases, facilitating the passage of waste gas.

[0041] When cleaning impurities, the multi-stage electric telescopic rod 24 is activated to shorten. The multi-stage electric telescopic rod 24, via the connecting rod 33, moves the impurity container 28 to one side, causing the sealing platform 59 to move into the processing space. This causes the partition platform 60 on the inlet / outlet side to move away from the tower body 1, and the partition platform 60 on the other side of the tower body 1 to move closer to the tower body 1. As the partition platform 60 moves away from the tower body 1, the rotating plate 30 on one side of this partition platform 60 rotates downwards under gravity, opening the square opening 29. The push wheel 31 supports the rotating plate 30, allowing it to be tilted and guiding the solution. As the liquid flows downwards, it can also rinse the impurities on the rotating plate 30. The slow movement of the impurity collection box 28 rinses the impurities on the rotating plate 30, ensuring that both the solution and impurities fall into the collection box 32. At this time, the liquid level in the processing space decreases. When the impurity collection box 28 moves, the first circular hole 39 moves to one side, blocking the drain pipe 12 and preventing solution leakage. This ensures that the solution in the solution tank 7 only flows out, facilitating solution replacement. When the inlet and outlet 27 are opened, a small amount of waste gas will be discharged, but since the waste gas has already been treated by solution spraying, not much harmful substance will escape. Further improvements will be made to reduce waste gas leakage.

[0042] When preparing to change the solution, first start the stirrer 55 to stir the solution in the feeding tank 13. After the solution in the solution tank 7 is basically drained, the multi-stage electric telescopic rod 24 is shortened, and the pressing platform 26 is moved to the side of the first button valve 14 via the moving rod 25. When the pressing platform 26 moves to the side of the first button valve 14, the first button valve 14 can be opened. At this time, the partition platform 60 moves to the other side of the processing space and closes one inlet and outlet 27. The sealing platform 59 located outside the processing space can close the other inlet and outlet 27. At this time, the second round hole 40 moves to the side of the drain pipe 12, allowing the solution to enter the solution tank 7 through the drain pipe 12, realizing solution recycling. After the first button valve 14 is opened, the solution can be added to the solution tank 7 through the first guide pipe 15. After a period of time, the solution in the feeding tank 13 is completely added. Then, the multi-stage electric telescopic rod 24 is shortened again, and the pressing platform 26 is moved to the side of the second button valve 18 via the moving rod 25. At this time, the first button valve 14 automatically closes. Then, the second button valve 18 is opened, allowing the liquid solute in the metering tank 17 to enter the feeding tank 13 through the second feed pipe 19. After addition, the multi-stage electric telescopic rod 24 is re-activated to shorten, and the pressing table 26 can be moved to the side of the third button valve 20 by the moving rod 25. At this time, the second button valve 18 automatically closes, and the third button valve 20 is opened, allowing the liquid solute in the liquid solute tank 16 to enter the metering tank 17 for metering. The multi-stage electric telescopic rod 24 is re-activated to shorten, and the pressing table 26 can be moved to the side of the third button valve 20 by the moving rod 25. The lever 25 can move the pressing table 26 to the side of the fourth button valve 23. At this time, the third button valve 20 automatically closes and the fourth button valve 23 opens, allowing water to enter the feeding box 13 through the fourth button valve 23. Air in the feeding box 13 can be discharged through the exhaust valve 22, which facilitates water entry and prevents water leakage from the exhaust valve 22. After water addition is completed, the multi-stage electric telescopic rod 24 is activated to extend, which can push the moving lever 25, the pressing table 26, and the impurity collection box 28 back to their original positions.

[0043] Impurities and solutions falling from the impurity collection box 28 enter the collection box 32, where they undergo solid-liquid separation via the filter screen 41. The liquid flows through the waste liquid pipe 42 into the wastewater treatment device for processing. Once the impurities on the filter screen 41 are dried, the take-up motor 46 is started to rotate forward, driving the take-up reel 47 to rotate. The take-up reel 47 can then take up the connecting wire 48. After the connecting wire 48 passes through the fixed pulley 51 to change the direction of tension, it can pull up one end of the filter plate 44, causing the filter plate 44 to rotate around the hinge. Then, the vibrator 52 is started, causing the impurities on the filter plate 44 to move downwards and be discharged through the discharge port 53 and discharge channel 54. Then, the take-up motor 46 is started to rotate in reverse, releasing the connecting wire 48 and allowing the filter plate 44 to return to its original position. Finally, the vibrator 52 is turned off.

[0044] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
