Description

Technical Field

[0001] This utility model relates to the field of acid mist purification, and in particular to a multi-stage acid mist purification scrubbing tower device. Background Technology

[0002] Acid mist purification scrubbing tower is an environmental protection device used to treat acidic waste gas in industrial production. The tower is equipped with a spray system, a packing layer and a top demister. During operation, the acidic waste gas enters from the bottom of the tower and reacts with the sprayed alkaline solution in the packing layer to be neutralized and purified. After the water vapor is removed by the demister, it meets the emission standards. It has the characteristics of high purification efficiency and simple operation, and is widely used in chemical, electroplating and other industries.

[0003] In current acid mist purification scrubbing towers, the bottom of the tower is connected to a water tank so that the circulating pump can continuously draw the absorbent stored at the bottom of the tower for recycling. However, when the absorbent in the water tank passes through the packing, it easily carries away some solid particles or debris, which accumulate on the water surface to form floating matter. At the same time, the chemical reaction between the spray liquid and acid mist in the tower also easily produces floating matter. Therefore, it is necessary for staff to open the water tank cover periodically for inspection and retrieval to prevent excessive accumulation of floating matter, which would adversely affect the normal recycling of the absorbent. However, the traditional water tank cover design makes it inconvenient for workers to check the inside of the water tank and to retrieve the debris. Retrieval is mostly done by using a net, which is slow and often time-consuming and labor-intensive.

[0004] Therefore, it is necessary to provide a new multi-stage acid mist purification and scrubbing tower device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a multi-stage acid mist purification and washing tower device that allows users to easily view the internal condition of the water tank and to quickly retrieve salvager particles.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-stage acid mist purification and scrubbing tower device, comprising: a scrubbing tower body, a storage structure, a circulation structure, and a retrieval structure. The scrubbing tower body includes a tower body, the storage structure includes a water tank, a filter screen is fixedly connected to the inner wall of the water tank, an opening is provided on the inner wall of the water tank located to the left of the filter screen, and an opening corresponding to the opening is provided on the surface of the tower body. The interior of the tower body and the interior of the water tank are connected through the openings one and two. The retrieval structure and the circulation structure are both installed on the surface of the water tank.

[0007] The salvage structure includes a positioning component located on the front side of the opening and fixedly connected to the inner wall of the water tank. A square frame is provided on the upper side of the positioning component. Handles are fixedly connected to the top left and right edges of the square frame. First folding frames are hinged to the inner wall surfaces of the front and rear sides of the square frame. Second folding frames are hinged to the ends of the first folding frames. The two adjacent ends of the second folding frames abut against each other. Filter screens are fixedly connected to the surfaces of the first folding frames and the second folding frames.

[0008] An opening is provided on the top of the water tank located on one side of the passage. A top cover is hinged to the top of the water tank located behind the opening. Limiting members are fixedly connected to the ends of the top cover symmetrically on the left and right. An adjusting screw is provided on the inner side of the limiting member. The bottom of the adjusting screw is hinged to the front wall surface of the water tank. A locking nut is threaded onto the surface of the adjusting screw. A washer is fitted on the surface of the adjusting screw located below the locking nut. The washer abuts against the top of the limiting member.

[0009] As a further embodiment of this utility model, a replenishing pipe is fixedly connected to the side wall surface of the water tank near the opening one. A valve body one is fixedly connected to the end of the replenishing pipe. An overflow pipe is fixedly connected to the side wall surface of the water tank on one side of the replenishing pipe. A drain pipe is fixedly connected to the side wall surface of the water tank below the overflow pipe. A valve body two is fixedly connected to the end of the drain pipe. A connecting pipe is fixedly connected to the other end of the valve body two. The drain pipe, overflow pipe, and replenishing pipe are all connected to the inside of the water tank. The lower end of the overflow pipe is connected to the inside of the connecting pipe.

[0010] With the above technical solution, the other end of valve body one needs to be connected to an external water pipe. When the float-type liquid level sensor detects that the liquid level inside the water tank is lower than the set value, valve body one can be opened to inject external absorbent liquid into the water tank. The drain pipe is used to discharge the waste liquid inside the water tank, while the overflow pipe is used to allow excess liquid to flow away when the liquid level inside the water tank is too high.

[0011] As a further embodiment of this utility model, a control module is fixedly connected to the side wall surface of the water tank away from the replenishment pipe, and a pH meter and a float-type liquid level sensor are fixedly connected to the top surface of the water tank near the control module. The detection ends of the pH meter and the float-type liquid level sensor are both located inside the water tank.

[0012] Through the above technical solution, the pH meter is used to monitor the acidity or alkalinity of the absorbent liquid inside the water tank. When the acidity or alkalinity is not up to standard, the user can open the top cover to replenish and adjust it.

[0013] As a further embodiment of this utility model, a plurality of longitudinally spaced grid plates are fixedly connected to the inner wall of the tower body. A demister is fixedly connected to the upper surface of the top grid plate. An air outlet pipe is fixedly connected to the top of the tower body. An air inlet pipe is fixedly connected to the outer peripheral surface of the tower body between the bottom grid plate and the opening. Both the air inlet pipe and the air outlet pipe are connected to the interior of the tower body.

[0014] With the above technical solution, the air inlet pipe needs to be connected to the external acid mist pipe, and the air outlet pipe is connected to the external fan and other equipment. Except for the top grating plate, all other grating plates are used to fill the packing. Manholes are provided on the upper part of the tower body of the grating plate and the tower body on the side of the air inlet pipe. The manhole ends are fixed with viewing windows to facilitate workers to observe and maintain the packing. In addition, since the entire equipment is used to treat acid mist and the absorbent is also alkaline, all components and equipment in the structure need to be manufactured to ensure that they have good acid and alkali corrosion resistance.

[0015] As a further embodiment of this utility model, the circulation structure includes a circulation pump, which is located in front of the pH meter and fixedly connected to the top of the water tank. A vertical pipe is fixedly connected to the input end of the circulation pump, and the vertical pipe passes through the top of the water tank. A communicating vessel is fixedly connected to the output end of the circulation pump through a pipe. A water distributor is fixedly connected to the bottom of each of the several grid plates, and the input end of the water distributor is connected to the communicating vessel through a pipe.

[0016] With the above technical solution, when using this circulation structure, the circulation pump is started, and the absorbent liquid filtered by the filter screen inside the water tank is drawn through the vertical pipe, then enters the communicating vessel and pipeline, and finally is discharged through several water distributors to spray acid mist inside the tower.

[0017] As a further embodiment of this utility model, the pH meter, float-type liquid level sensor, circulating pump, and valve body one and valve body two are all electrically connected to the control module.

[0018] By electrically connecting each device in the structure to the control module, the above technical solution facilitates the user's control over the opening and closing of each device, thereby better completing the acid mist purification operation.

[0019] Compared with related technologies, the multi-stage acid mist purification and scrubbing tower device provided by this utility model has the following beneficial effects:

[0020] To facilitate workers' observation of the part of the water tank that connects to the tower, this device features an opening on the top of the water tank on the left side of the filter screen, which is then sealed with a top cover. When inspecting and retrieving items, workers must first wear full protective gear, then loosen the two locking nuts and turn the adjusting screw to flip the top cover to one side. This exposes the internal environment of the water tank on the left side of the filter screen, allowing users to observe the state of floating debris. Next, the two sets of first and second folding frames are folded in half and submerged until they rest on the positioning piece. The first and second folding frames are then unfolded again, and the top opening of the frame is covered by four filter screens. Once the water surface is calm, the handle is gripped and the device is slowly lifted to retrieve most of the floating debris from inside the water tank. Compared to traditional water tank cover structures and retrieval net designs, this structure is more convenient and quick to operate, and its design is reasonable. Attached Figure Description

The lower end of the overflow pipe 6 is connected to the inside of the connecting pipe.

[0034] The other end of the valve body needs to be connected to an external water pipe.

[0036] pH meter 17 is used to monitor the acidity or alkalinity of the absorbent liquid inside water tank 13. When the acidity or alkalinity is not up to standard, the user can open the top cover 14 to replenish and adjust it.

[0037] like Figure 1-5 As shown, a number of grid plates 8 are fixedly connected to the inner wall of the tower body 11 in a longitudinally evenly spaced manner. A demister 10 is fixedly connected to the upper surface of the top grid plate 8. An air outlet pipe 5 is fixedly connected to the top of the tower body 11. An air inlet pipe 4 is fixedly connected to the outer circumference of the tower body 11 between the bottom grid plate 8 and the opening. Both the air inlet pipe 4 and the air outlet pipe 5 are connected to the interior of the tower body 11.

[0038] The air inlet pipe 4 needs to be connected to the external acid mist pipe, while the air outlet pipe 5 is connected to the external fan and other equipment. Except for the top grating plate 8, all other grating plates 8 are used to fill the packing. Manholes are provided on the tower body 11 on the upper side of the grating plate 8 and on the tower body 11 on the side of the air inlet pipe 4. A viewing window is fixed at the end of the manhole to facilitate workers to observe and maintain the packing. In addition, since the entire equipment is used to treat acid mist and the absorbent is alkaline, all components and equipment in the structure need to be manufactured to ensure that they have good resistance to acid and alkali corrosion.

[0039] like Figure 1-5 As shown, the circulation structure 3 includes a circulation pump 15, which is located in front of the pH meter 17 and fixedly connected to the top of the water tank 13.

[0043] The working principle of the multi-stage acid mist purification and scrubbing tower device provided by this utility model is as follows:

[0044] To facilitate workers' observation of the part of the water tank 13 that connects to the tower body 11, the top of the water tank 13 on the left side of the filter screen 12 is specially designed as an opening, which is then sealed with a top cover 14. When workers conduct inspections and retrieval operations, since they need to come into contact with the absorbent liquid, they must first put on full protective gear, then loosen the two locking nuts 20 and turn the adjusting screw 19 to flip the top cover 14 to one side. At this time, the internal environment of the water tank 13 on the left side of the filter screen 12 is exposed, making it easier for users to observe the state of the floating objects on top. Then, the two sets of first folding frames 27 and second folding frames 28 are folded in half and then submerged in the water until they are attached to the positioning piece 26. Next, the first folding frames 27 and second folding frames 28 are unfolded again, and the top opening of the square frame 25 is covered by four filter screens 29. After the water surface is calm, the handle 24 is grasped and the tank is slowly lifted to retrieve most of the floating objects inside the water tank 13. Compared with the traditional water tank 13 cover structure and retrieval net design, this structure is more convenient for users to operate quickly and is reasonably designed.
