[0061] Please see Figures 1 to 5 This embodiment provides an acid mist absorption and purification system, comprising:

[0062] The pry bar 1 is provided with a base 11 and a push handle 12. The base 11 is provided with a limiting part 111, and the base 11 is provided with a traveling wheel 112.

[0063] A water tank 2 is placed in the limiting part 111. An acid mist absorption port 21 and a water inlet 22 are provided in the middle of the side wall of the water tank 2. A partition 23 is horizontally provided in the middle of the inner cavity of the water tank 2. The partition 23 is located below the acid mist absorption port 21 and the water inlet 22. A mixing port 231 is provided on the partition 23. The mixing port 231 is located close to the water inlet 22. A spray inlet 24 is provided at the upper part of the water tank 2. A water outlet 25 is provided at the lower part of the water tank 2. The water outlet 25 is connected to the spray inlet 24 through a spray circulation pump 3 and a pipe.

[0064] The limiting part 111 can be a through hole provided on the base 11. The bottom of the water tank 2 is engaged with the limiting part 111, so that the water tank 2 and the base 11 are fixed together. When the worker pushes the handle 12, the water tank 2 and the base 11 are relatively stable and the water tank 2 will not shake. Of course, the limiting part 111 can also be a groove structure recessed in the base 11. This groove structure is adapted to the bottom of the water tank 2 to fix the water tank 2.

[0065] Four wheels 112 are provided, located at the four corners of the base 11. The wheels 112 can be configured as omnidirectional wheels for the user to push.

[0066] The acid mist absorption port 21 of water tank 2 is connected to an external acid mist treatment pipeline, and the water inlet 22 of water tank 2 is connected to an external water source. After the acid mist enters the tank, it will be rinsed by water on the baffle 23 to achieve purification and absorption of the acid mist. The mixing port 231 on the baffle 23 facilitates the flow of injected water into the bottom of water tank 2, which is then collected and pumped to the top of water tank 2 for reuse by the spray circulation pump 3. The position of the mixing port 231 is close to the water inlet 22, which also facilitates the water source to enter the bottom of water tank 2 more quickly, increasing the water volume in the tank, increasing the water pressure, and facilitating the spray circulation pump 3 to pump water from the outlet 25 to the spray inlet 24.

[0067] To better design the structure of the water tank 2, the acid mist absorption port 21, water inlet 22, water outlet 25, and spray inlet 24 are all located on the side wall of the water tank 2.

[0068] In this application, the water tank 2 is placed on the skid base 1 for easy movement, adapting to different on-site acid mist treatment needs. This application also incorporates a baffle 23, allowing the acid mist to be absorbed by the water flow injected through the water inlet 22 at the baffle 23, and then the water in the tank 2 is further circulated and sprayed, improving the absorption and purification effect of the acid mist. This application features a simple structure and ease of use.

[0069] In some embodiments, a first pipe 31 connects the outlet 25 to the inlet of the spray circulation pump 3. A first valve 41 is installed on the first pipe 31 to control the flow between the outlet 25 and the inlet. A sampling port 311 is also installed on the first pipe 31, and a second valve 42 is installed at the sampling port 311. The spray circulation pump 3 can be placed on the base 11 or bolted to it to prevent vibration from affecting the system. When the acid mist absorption and purification system stops working, the first valve 41 can be operated to stop the liquid supply to the spray circulation pump 3. The second valve 42 controls the opening and closing of the sampling port 311. After opening the second valve 42, a sample can be taken from the water tank 2 to measure the pH value of the liquid in the water tank 2, thereby determining the acid mist treatment status in the water tank 2. The first valve 41 and the second valve 42 are preferably manual ball valves.

[0070] In some embodiments, a second pipe 32 connects the pump outlet of the spray circulation pump 3 to the spray inlet 24. The second pipe 32 is equipped with a third valve 43 and a fourth valve 44 to control the flow between the pump outlet and the spray inlet 24. A return port 321 is also provided on the second pipe 32, located between the third valve 43 and the fourth valve 44. A fifth valve 45 is located at the return port 321. The second pipe 32 rises vertically, pumping liquid from the lower outlet 25 to the spray inlet 24. The third valve 43 and the fourth valve 44 control the opening and closing of the output pipe of the spray circulation pump 3. The return port 321 is connected to an external acid tank. When the pH value of the liquid in the water tank 2 reaches a certain acidity, the liquid in the water tank 2 is discharged through the return port 321. The discharge power of the return port 321 and the power for the circulating spray are both provided by the spray circulation pump 3. The fifth valve 45 at the return port 321 is used to control the on / off state of the return port 321. The third valve 43, the fourth valve 44, and the fifth valve are preferably manual ball valves.

[0071] In some embodiments, a pipe support frame 121 is provided on the side of the push handle 12 facing the limiting part 111, and the second pipe 32 abuts against the pipe support frame 121. The second pipe 32 rises vertically to the outside of the water tank 2. The pipe support frame 121 on the push handle 12 can effectively support the second pipe 32 and prevent the second pipe 32 from shaking, causing leakage at the connection. Specifically, the pipe support frame 121 is a rod-shaped structure protruding from the surface of the push handle 12, and is provided at least on both sides of the second pipe 32 to provide support and fixation on both sides of the second pipe 32. Multiple pipe support frames 121 can also be provided along the length extension direction of the second pipe 32 to provide better support for the second pipe 32.

[0072] In some embodiments, a packing layer is horizontally arranged inside the water tank 2, positioned above the partition 23. The packing layer includes a packing support 261 and packing material 262 placed on the support 261. The support 261 has uniformly distributed through-holes. The packing material 262 can be a multi-faceted hollow sphere used to purify gases such as oxygen, chlorine, and carbon dioxide in the acid mist. During the upward discharge process, the acid mist passes evenly through the through-holes in the support 261 and then through the multi-faceted hollow spheres, achieving effective purification.

[0073] In some embodiments, the top of the inner cavity of the water tank 2 is provided with a first spray pipe 271 and a second spray pipe arranged in an alternating manner, with spray nozzles evenly distributed on the first spray pipe 271 and the second spray pipe. The first spray pipe 271 and the second spray pipe are arranged vertically and are interconnected internally, with the spray nozzles pointing vertically downwards. Water in the water tank 2 flows out from the outlet 25 and is then transported through a pipe to the spray inlet 24, and then sprayed into the water tank 2 from the spray nozzles on the first spray pipe 271 and the second spray pipe, with the spray water continuing to absorb and purify the acid mist.

[0074] In some embodiments, the acid mist absorption port 21 is positioned away from the mixing port 231. This has the advantage that the acid mist entering the water tank 2 from the acid mist absorption port 21 will remain on the baffle 23 for a longer period, allowing the acid mist to fully contact the water injected through the water inlet 22 and improving the purification effect of the acid mist.

[0075] In some embodiments, a level gauge 5 is also installed on the side wall of the water tank 2. Specifically, two level gauge holes 5 are provided on the side wall of the water tank 2, and the level gauge 5 is inserted into the water tank 2 through the two level gauge holes 5, so that workers can observe the water level in the water tank 2 by observing the level gauge 5.

[0076] In some embodiments, the top of the water tank 2 is provided with an exhaust port 28. The exhaust port 28 is connected to an external pipe for external discharge, which prevents excessive pressure inside the water tank 2. After the acid mist in the water tank is purified, it can be discharged outdoors through the external pipe connected to the exhaust port 28, preventing a large amount of mist from directly overflowing into the room.

[0077] The following is a usage scenario for this acid mist absorption and purification system: External tap water is added to the water tank through inlet 22. The water level is monitored using level gauge 5. When the level reaches 90%, the tap water is shut off. The first, third, and fourth valves are opened, and the spray circulation pump 3 is activated via the PLC control cabinet to perform acid mist absorption spraying and demisting. After a period of time, the liquid color is observed using the level gauge. A sample is taken by opening the second valve. Once the liquid pH reaches the required acidic concentration, the fourth valve on the inlet pipe of the spray circulation pump is closed, and the fifth valve (return) is opened to return the liquid to the acid tank. Water is then refilled, and the system is recycled. When not in use, the water tank can be emptied through the second valve. After emptying the tank, the acid mist absorption and purification system can be placed in an unused corner using the casters on the skid mount for future use.

[0078] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
