However, existing alkaline scrubbing towers do not allow for cleaning of their inner walls during use. Over time, this can lead to solidification on the inner walls, reducing the tower's efficiency in treating acidic waste gases and thus limiting its practicality.

[0003] A search revealed a Chinese patent document (authorization announcement number CN222196502U) for a high-efficiency alkaline washing tower with waste liquid recovery function. The tower includes a washing liquid tank, a washing tower mounted on top of the tank, a partition plate fixedly installed inside the tank, a first hydraulic rod fixedly installed on the inner bottom wall of the tank, a liquid outlet on the surface of the partition plate, a sealing plug fixedly installed on the upper part of the fixed plate, a filter fixedly installed on the right side of the tank, a first pump fixedly installed on the right side of the tank, and a second pump fixedly installed on the left side of the tank. This device solves the problem of inconvenient waste liquid recovery in existing equipment. However, it still has the problem of not being able to clean the inner wall of the device during use, reducing its practicality. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency alkaline washing tower with waste liquid recovery function, comprising:

[0006] The square box has a movable panel on one side for easy cleaning, and the top of the square box is connected to a column for treating acidic industrial waste gas. The top of the column is equipped with a feed pipe for treating waste gas.

[0007] Multiple shelves are evenly arranged inside the column. The sidewalls of the shelves are fixed to the inner wall of the column. A hollow connecting pipe connects the inner wall of the column and the shelves, and the connecting pipe communicates with the shelves.

[0008] The fixed plate is disc-shaped. One side of the fixed plate is connected to the exhaust pipe. The middle of the fixed plate is also provided with several through holes for uniform gas dispersion. The through holes are connected to the exhaust pipe. The top of the fixed plate is fixed to the bottom of the column, and the bottom of the fixed plate is welded to the top of the square box.

[0009] As a preferred embodiment, a waterproof linear motor is fixed to the inner bottom wall of the column. The linear motor is located on both sides of the connecting pipe, and the other end of the linear motor is fixed to the shelf.

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0032] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0033] An embodiment of a high-efficiency alkaline scrubbing tower with waste liquid recovery function, such as... Figures 1 to 8 As shown,

[0034] include:

[0035] The square box 1 has support legs welded to its bottom. These legs can separate the device from the ground, facilitating ventilation, reducing moisture corrosion on the device's outer casing, and extending the device's service life. One side of the square box 1 is equipped with a movable plate 3 for easy cleaning. The side wall of the movable plate 3 is hinged to the side wall of the square box 1 via a hinge and secured by a latch. By opening the movable plate 3 using the latch and hinge, the internal structure of the square box 1 can be inspected and cleaned, facilitating operation.

[0036] Multiple side plates 9 are provided inside the square box 1. Waterproof and moisture-proof high-frequency telescopic electric actuators 10 are installed inside the side plates 9. The moving part of the electric actuator 10 is connected to a semi-circular ball connector 11 installed at the bottom of the screen plate 7. The ball connector 11 is movably connected to the moving part of the electric actuator 10. A screen 8 is also installed inside the screen plate 7. The water sprayed is filtered through the screen plate 7 and the electric actuator 10, which facilitates recycling.

[0037] The top of the square box 1 is fixed with a hollow fixing plate 6. One side of the fixing plate 6 is provided with an exhaust pipe 2 for industrial exhaust gas communication. The exhaust pipe 2 is connected to several through holes 16 set inside the fixing plate 6, so that the exhaust gas can be evenly distributed inside the column 4. The top of the fixing plate 6 is fixed to the bottom of the column 4, so that the diffusion and treatment of exhaust gas can be completed through the setting of the through holes 16.

[0038] The top of the column 4 is provided with a feed pipe 5 for treating exhaust gas. The feed pipe 5 passes through the top of the column 4 and is connected to the hollow connecting pipe 12. The end of the connecting pipe 12 is connected to the inner wall of the column 4. Multiple shelves 15 are evenly arranged inside the column 4. The side walls of the multiple shelves 15 are fixed to the inner wall of the column 4. In order to ensure that the exhaust gas inside the column 4 rises normally, the side walls of the shelves 15 are fixed to the inner wall of the column 4 by welded connecting blocks, so that the treated exhaust gas can enter the inner top of the column 4, and an exhaust pipe is set at the inner top to complete the discharge of the treated exhaust gas.

[0039] A hollow connecting pipe 12 connects the inner wall of the column 4 and the shelf 15. The connecting pipe 12 communicates with the shelf 15. Several nozzles 18 are connected to the bottom of the shelf 15 at equal intervals. Spray holes 19 are arranged symmetrically around the outside of the nozzles 18. The spray holes 19 can spray out the liquid that treats the waste gas through the connecting pipe 12 and the shelf 15. The arrangement of multiple spray holes 19 and nozzles 18 allows the treatment liquid and waste gas to be fully mixed, improving the treatment effect of the device.

[0040] Two waterproof and moisture-proof linear motors 14 are installed on both sides of the connecting pipe 12. The moving part of the linear motor 14 is fixed with a connecting plate. The inner wall of the connecting plate is slidably connected to the connecting pipe 12. Four fixing rods 17 are welded to the outer side of the connecting plate. The other end of the fixing rods 17 is fixed to the annular scraper 13. The moving part is driven by the linear motor 14 to move, which drives the connecting plate, fixing rods 17 and scraper 13 to move, thus cleaning the inner wall of the column 4. This avoids the device from being used for a long time, which would cause a large amount of hardened crystalline solids to adhere to the inner wall, making it easier to use.

[0041] The electric actuator 10 and the linear motor 14 are conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. Since the above-mentioned equipment is in a humid environment for a long time, it is waterproofed and moisture-proofed, and regularly inspected and replaced. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0042] Working principle

[0043] This high-efficiency alkaline scrubbing tower with waste liquid recovery function, when in use, the liquid for treating waste gas is transported into the interior of the connecting pipe 12 through the feed pipe 5, and sprayed out through the nozzle 18 and spray hole 19. Then, the waste gas pipe 2 carrying industrial waste gas is opened, and the waste gas is evenly diffused into the interior of the column 4 through the through hole 16. At this time, the liquid comes into contact with the waste gas, and the acidic gas in the waste gas is treated. The moving part of the linear motor 14 is controlled to move, driving the connected scraper 13 to move and clean the inner wall of the column 4. At the same time, the moving part of the high-frequency telescopic electric push rod 10 is controlled to work, driving the connected mesh plate 7 to move on the top of the side plate 9, completing the treatment of the liquid and recycling it. The treated waste gas can be discharged through the set gas outlet pipe.
