Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: a spraying device for treating acid-base waste gas, including a processing chamber 1. The lower end of the rear side of the processing chamber 1 is provided with an air delivery pipe 2. The front end of the air delivery pipe 2 is connected to a diverging pipe 3. A partition board 4 is fixedly installed inside the processing chamber 1. The front end of the diverging pipe 3 is connected to a valve 31. There are two valves 31 arranged symmetrically left and right. The front end of the valve 31 extends into the inside of the processing chamber 1 and is connected to the left and right sides of the partition board 4. When the filter plate 5 or the packing trough plate 9 needs to be replaced, close the valve 31 on one side to make the air flow temporarily not circulate on this side of the partition board 4, avoiding the leakage of waste gas;

[0026] Filter plates 5 are arranged on the left and right sides of the partition board 4 inside the processing chamber 1. A liquid collecting plate 6 is arranged above the filter plate 5. A ventilation pipe 7 is arranged at the upper end of the liquid collecting plate 6. Spraying pipes 8 are arranged on the left and right sides of the ventilation pipe 7 at the upper end of the liquid collecting plate 6. The liquid collecting plate 6 is fixedly connected to the inner side of the processing chamber 1 and the surface of the partition board 4. The lower end of the ventilation pipe 7 is connected to the lower end of the liquid collecting plate 6. A conical baffle 71 is fixedly installed at the upper end of the ventilation pipe 7. The lower end of the spraying pipe 8 is connected to a micro water pump 81. The lower end of the micro water pump 81 is fixedly connected to the surface of the liquid collecting plate 6. Nozzles are arranged at the upper end of the spraying pipe 8. After the waste gas is filtered by the filter plate 5, it enters above the liquid collecting plate 6 from the ventilation pipe 7. The micro water pump 81 works to drive the spraying water to be sprayed above the liquid collecting plate 6, enabling the waste gas to fully contact the spraying water and realizing the preliminary treatment of the waste gas;

[0027] Above the liquid collecting plate 6, there is a packing trough plate 9. There are two filter plates 5 arranged symmetrically left and right. The front ends of the filter plates 5 and the packing trough plate 9 extend to the outside of the treatment chamber 1 through the through groove 100, and a sealing cover 101 is fixedly installed. The rear end of the sealing cover 101 is hermetically connected to the inner side of the through groove 100. The sides of the filter plates 5 and the packing trough plate 9 are slidably connected to the inner side of the treatment chamber 1 and the surface of the partition plate 4 through sliding grooves. The rear ends of the filter plates 5 and the packing trough plate 9 are provided with the same mounting seats 10. The front ends of the mounting seats 10 are provided with clamping plates 11. The sides of the mounting seats 10 are slidably connected to the inner side of the treatment chamber 1 and the surface of the partition plate 4 through sliding grooves. The front ends of the mounting seats 10 are adapted to the rear sides of the filter plates 5 and the packing trough plate 9, and are also adapted to the inner side of the through groove 100. The clamping plates 11 are designed in an L-shaped structure and are fixedly connected to the front ends of the mounting seats 10. The rear ends of the filter plates 5 and the packing trough plate 9 are snap-connected to the clamping plates 11 through snap grooves. On the left and right sides of the treatment chamber 1, a circulation pump 12 is fixedly installed. Above the packing trough plate 9, there is a spray chamber 13. The input end of the circulation pump 12 extends into the treatment chamber 1 through a pipeline and is connected to the side of the upper end of the liquid collecting plate 6. The output end of the circulation pump 12 extends into the treatment chamber 1 through a pipeline and is connected to the inner side of the spray chamber 13. The spray chamber 13 is fixedly connected to the inner side of the treatment chamber 1 and is adapted to the upper end of the packing trough plate 9. The lower end of the spray chamber 13 is provided with nozzles arranged in an array. The upper end of the treatment chamber 1 is connected to an exhaust pipe 14. The circulation pump 12 drives the sprayed water to be input into the spray chamber 13 to realize the circulating spraying of the packing trough plate 9. After the waste gas is fully treated by the packing trough plate 9, it is concentrated at the upper end of the partition plate 4 and discharged from the exhaust pipe 14. When it is necessary to replace the filter plate 5 or the packing trough plate 9, close the valve 31 on one side to make the air flow not circulate on this side of the partition plate 4 temporarily, and then pull the sealing cover 101 on this side to drive the filter plate 5 or the packing trough plate 9 to move to the outside of the treatment chamber 1 through the through groove 100 until the mounting seat 10 blocks the through groove 100. At this time, lift the filter plate 5 or the packing trough plate 9 to make the snap groove at its rear end disengage from the clamping plate 11, and then it can be removed and replaced.

[0028] In use, waste gas is input into the treatment chamber 1 through the gas delivery pipe 2 and the shunt pipe 3. After being filtered by the filter plate 5, the waste gas enters above the liquid collection plate 6 through the ventilation pipe 7. The micro water pump 81 operates to drive the spraying of the spray water above the liquid collection plate 6, enabling the waste gas to come into full contact with the spray water, achieving the preliminary treatment of the waste gas. At the same time, the circulation pump 12 drives the spray water to be input into the spray chamber 13, realizing the circulating spraying of the packing trough plate 9. After being fully treated by the packing trough plate 9, the waste gas gathers at the upper end of the partition plate 4 and is discharged from the exhaust pipe 14. When it is necessary to replace the filter plate 5 or the packing trough plate 9, close the valve 31 on one side to temporarily stop the air flow from passing through this side of the partition plate 4. Then, by pulling the sealing cover 101 on this side, the filter plate 5 or the packing trough plate 9 can be driven to move to the outside of the treatment chamber 1 through the through groove 100 until the mounting seat 10 blocks the through groove 100. At this time, lift the filter plate 5 or the packing trough plate 9 to disengage the engaging groove at its rear end from the engaging plate 11, and then it can be removed and replaced. Subsequently, reset the replaced filter plate 5 or the packing trough plate 9, and then the valve 31 on this side can be opened, and repeat the above operations to replace the other side.
