Specific Embodiments

[0017] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0018] According to Figure 1 、 2, as shown in Figures 3, an acid-base tail gas treatment water washing system is proposed in this embodiment, including a bottom plate 1. A treatment chamber 2 is installed at the top of the bottom plate 1. Support columns 3 are installed at the bottom of the treatment chamber 2. A partition plate 4 is installed inside the treatment chamber 2. An air inlet 5 is installed on one side of the treatment chamber 2. An acidic treatment tank 6 is installed on one side of the top of the bottom plate 1. One end of the treatment chamber 2 is connected to the lower part of one side of the acidic treatment tank 6 through a pipeline. A one-way valve is arranged inside the pipeline. An alkaline treatment tank 7 is installed on one side of the acidic treatment tank 6 at the top of the bottom plate 1. An air delivery pipe 10 is installed above one side of the acidic treatment tank 6. One end of the air delivery pipe 10 is communicated with the lower part of one side of the alkaline treatment tank 7. A one-way valve is arranged inside the air delivery pipe 10. An exhaust port 11 is installed above one side of the alkaline treatment tank 7. Support legs 12 are installed at the bottoms of both the acidic treatment tank 6 and the alkaline treatment tank 7. Liquid inlet ports 8 are installed at the tops of both the acidic treatment tank 6 and the alkaline treatment tank 7. Liquid outlet ports 9 are installed at the bottoms of both the acidic treatment tank 6 and the alkaline treatment tank 7. A filtering mechanism is arranged on one side inside the treatment chamber 2. A spraying mechanism is arranged on the other side inside the treatment chamber 2.

[0019] The filtering mechanism includes a filter plate 13, mounting grooves 14, mounting rails 15 and a positioning structure. The filter plate 13 is installed inside the treatment chamber 2. Mounting grooves 14 are provided above and below the inside of the treatment chamber 2. Mounting rails 15 are arranged inside the mounting grooves 14. One end of each mounting rail 15 is connected to one end of the filter plate 13. The positioning structure includes positioning holes 16, positioning blocks 17 and telescopic springs 18. The telescopic springs 18 are installed above and below the inside of the treatment chamber 2. One end of each telescopic spring 18 is provided with a positioning block 17. The positioning holes 16 are opened at both ends of the mounting rail 15. One end of the positioning block 17 extends into the positioning holes 16. The cross-section of the mounting groove 14 is larger than that of the mounting rail 15. A sliding structure is formed between the mounting groove 14 and the mounting rail 15. The inner diameter of the positioning hole 16 is larger than the outer diameter of the positioning block 17. A clamping structure is formed between the positioning hole 16 and the positioning block 17. During use, acid-base tail gas is introduced into the inside of the treatment chamber 2 through the air inlet 5, and then the acid-base tail gas is filtered by the filter plate 13. The filtered acid-base tail gas enters the other side of the treatment chamber 2. When the filter plate 13 needs to be replaced, the staff pulls the filter plate 13 outwards. At this time, the positioning block 17 is squeezed, so that the telescopic spring 18 drives the positioning block 17 to contract, and the filter plate 13 can be removed from the inside of the treatment chamber 2. Finally, a new filter plate 13 is inserted into the inside of the treatment chamber 2. Since one end of the positioning block 17 is arc-shaped, at this time the filter plate 13 squeezes the positioning block 17, so that the telescopic spring 18 drives the positioning block 17 to contract. When the positioning hole 16 appears directly in front of the positioning block 17, the telescopic spring 18 drives the positioning block 17 to extend under the action of elastic force, so that the positioning hole 16 and the positioning block 17 are clamped with each other, completing the convenient installation of the filter plate 13. The acid-base tail gas can be filtered by the filter plate 13, making the effect of the acid-base tail gas during water washing treatment better and not likely to have a lot of garbage. At the same time, the filter plate 13 can be conveniently disassembled and installed, making the replacement of the filter plate 13 more convenient and efficient, thus greatly improving the practicability of the system during use.

[0020] The spray mechanism includes a water tank 19, a water pump 20, a water delivery pipe 21, a water storage cavity 22, and a spray head 23. The water tank 19 is installed at the bottom end of the treatment cavity 2. A water pump 20 is installed on one side of the water tank 19. One end of the water pump 20 is connected to one end of the water tank 19 through a pipe. The water storage cavity 22 is installed at the top end inside the treatment cavity 2. The other end of the water pump 20 is installed with a water delivery pipe 21. One end of the water delivery pipe 21 is connected to one end of the water storage cavity 22. A spray head 23 is installed below the water storage cavity 22. A plurality of the spray heads 23 are installed below the water storage cavity 22 and are equally spaced. During use, the water pump 20 is started, and the water inside the water tank 19 is pumped into the water storage cavity 22 through the water delivery pipe 21 and then sprayed out through the spray heads 23, so that the acid-base tail gas can be washed with recycled water, and the use of water resources can be saved.

[0021] Working principle: The staff passes the acid-base tail gas into the treatment cavity 2 through the air inlet 5, and then uses the filter plate 13 to filter the acid-base tail gas. The filtered acid-base tail gas enters the other side of the treatment cavity 2. At this time, the water pump 20 is started, and the water inside the water tank 19 is pumped into the water storage cavity 22 through the water delivery pipe 21 and then sprayed out through the spray heads 23 to wash the acid-base tail gas. Then the acid-base tail gas enters the inside of the acid treatment tank 6 through a pipe, and the acid-base tail gas is treated with the neutralizing liquid inside the acid treatment tank 6. At this time, the acid-base tail gas enters from below the alkaline treatment tank 7 through the air delivery pipe 10, and the acid-base tail gas is treated with the neutralizing liquid inside the alkaline treatment tank 7 and finally discharged from the exhaust port 11. When the filter plate 13 needs to be replaced, the staff pulls the filter plate 13 outwards. At this time, the positioning block 17 is squeezed, so that the telescopic spring 18 drives the positioning block 17 to contract, and the filter plate 13 can be removed from the inside of the treatment cavity 2. Finally, a new filter plate 13 is inserted into the inside of the treatment cavity 2. Since one end of the positioning block 17 is arc-shaped, the filter plate 13 squeezes the positioning block 17 at this time, so that the telescopic spring 18 drives the positioning block 17 to contract. When the positioning hole 16 appears directly in front of the positioning block 17, the telescopic spring 18 drives the positioning block 17 to extend under the action of the elastic force, so that the positioning hole 16 and the positioning block 17 are engaged with each other, and the convenient installation of the filter plate 13 is completed.
