Description

Technical Field

[0001] This utility model relates to the field of acid mist purification, and in particular to an acid mist purification scrubbing tower. 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 actual use, the internal packing of current acid mist purification scrubbing towers is prone to clogging and scaling after a period of operation, resulting in a decrease in purification efficiency. Alternatively, the packing material may age or break, requiring workers to clean out the packing and replace it with new one. Currently, the packing is cleaned through a manhole. To effectively collect waste, workers typically open a collection bag outside the manhole and then use a rake or other tools to scrape out the packing. However, the traditional structural design of acid mist purification scrubbing towers makes it inconvenient for users to secure the bag, making cleaning very difficult, time-consuming, and labor-intensive, often requiring multiple people to work together.

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

[0005] The technical problem solved by this utility model is to provide an acid mist purification and scrubbing tower that has a special support structure set on the outside of the pipe wall to open the collection bag, thereby facilitating workers to clean and collect the packing.

[0006] To solve the above-mentioned technical problems, the present invention provides an acid mist purification scrubbing tower comprising: a scrubbing tower body, a water storage structure, a circulation structure, and a support structure. The water storage structure and the circulation structure are installed on the scrubbing tower body. The scrubbing tower body includes a tower body. A plurality of longitudinally spaced grid plates are fixedly connected to the inner wall surface of the tower body. A demister is fixedly connected to the surface of the grid plate at the top. A connecting pipe is fixedly connected to the outer peripheral surface of the tower body above the plurality of grid plates. The connecting pipe communicates with the interior of the tower body. A viewing window is fixedly connected to the connecting pipe by bolts and nuts.

[0007] The bracket structure includes a mounting frame located outside the connecting pipe on one side. Ear plates 1 are fixedly connected to the left and right side walls of the mounting frame. Ear plates 2 are fixedly connected to the left and right side walls of several windows. Through holes are opened on the surfaces of ear plates 1 and ear plates 2. Pins are inserted into the through holes of ear plates 1 and ear plates 2 on the adjacent side. The rod part of the pin is in transition fit with the through hole.

[0008] A connector one is hinged to one side wall surface of the mounting bracket. A clamping frame is fixedly connected to one end of the connector one. The clamping frame is located on the lower side of the mounting bracket. A connector two is fixedly connected to one end of the clamping frame away from the connector one. An adjusting screw is hinged to one end of the connector two. A locking nut is threaded onto the surface of the adjusting screw. A washer is fitted onto the surface of the adjusting screw located below the locking nut. A limiting member is fixedly connected to one side wall surface of the mounting bracket away from the connector one. The adjusting screw is located inside the limiting member. The washer abuts against the top of the limiting member.

[0009] As a further embodiment of this utility model, the water storage structure includes a water tank, a filter screen fixedly connected to the inner wall of the water tank, an opening 1 on the inner wall of the water tank located on one side of the filter screen, and an opening 2 corresponding to the opening 1 on the surface of the tower body. The interior of the water tank and the interior of the tower body are connected through the opening 1 and the opening 2. A replenishment pipe is fixedly connected to the side wall surface of the water tank near the opening 1. A valve body 1 is fixedly connected to the end of the replenishment pipe and the replenishment pipe is connected to the interior of the water tank. An overflow pipe is fixedly connected to the side wall surface of the water tank located on one side of the replenishment pipe. A drain pipe is fixedly connected to the side wall surface of the water tank located below the overflow pipe. A valve body 2 is fixedly connected to the end of the drain pipe. A connecting pipe is fixedly connected to the other end of the valve body 2. The drain pipe is connected to the interior of the water tank. The two ends of the overflow pipe are connected to the interior of the water tank and the interior of the connecting pipe, respectively.

[0010] With the above technical solution, when the circulating pump is running, it will draw the absorbent liquid inside the water tank after it has been filtered by the filter screen through the vertical pipe, and then transport it to several water distributors through the connector and pipeline. After that, the absorbent liquid falls back to the bottom of the tower after passing through the upper packing of the grid plate. The function of the drain pipe is to discharge the waste liquid generated during long-term use after the user opens valve body two. The overflow pipe is to allow the liquid to flow away smoothly when the liquid level in the water tank is too high. The valve body one at the end of the replenishment pipe can be connected to the external pipeline to replenish the absorbent liquid when there is a lack in the water tank. Since this structure is used to purify and wash acid mist, and the absorbent liquid is alkaline, all components and equipment of the device must be ensured to have the effect of resisting acid and alkali corrosion before use.

[0011] As a further embodiment of this utility model, a liquid injection port is provided on the top surface of the water tank located on one side of the inlet. A water tank cover is hinged to the side wall surface of the liquid injection port. A control module is fixedly connected to the side wall surface of the water tank away from the inlet. A float-type liquid level sensor and a pH meter are fixedly connected to the top of the water tank on the side close to the control module. The detection ends of the pH meter and the float-type liquid level sensor both extend into the interior of 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, so that users can replenish it when the acidity or alkalinity is not up to standard, while the float-type liquid level sensor can monitor the liquid level inside the water tank. When the liquid level is too low, users need to add it in time.

[0013] As a further embodiment of this utility model, the circulation structure includes a circulation pump, which is fixedly connected to the top of the water tank in front of the pH meter. 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. Water distributors are fixedly connected to the inner wall surface of the tower body located below several of the grid plates. The input end of the water distributor is connected to the inside of the communicating vessel through a pipe.

[0014] Through the above technical solution, the circulating pump draws the filtered absorbent liquid from inside the water tank through the vertical pipe, and then enters several water distributors through the communicating vessel and pipelines, spraying it into the interior of the tower.

[0015] As a further embodiment of this utility model, an air inlet pipe is fixedly connected to the side wall surface of the tower body between the bottom grille plate and the opening, and an air outlet pipe is fixedly connected to the top of the tower body. Both the air inlet pipe and the air outlet pipe are connected to the interior of the tower body.

[0016] 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 equipped with corresponding external equipment such as fans to draw the mist outward.

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

[0018] By using the above technical solution, and by electrically connecting each electronic device in the structure to the control module, users can easily control the switching of each device, thereby better completing the acid mist purification work.

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

[0020] To facilitate workers' cleaning and collection of waste from the grating plate, this device features a specially designed support structure that can be fixed to the outside of the connecting pipe. This support structure secures and supports the collection bag. In operation, the worker first places the outer collection bag onto the clamping frame, then rotates the frame to push the adjusting screw inside the limiting component and rotates the locking nut, pressing the gasket against the limiting component. At this point, the top of the clamping frame and the bottom of the mounting bracket press the bag opening tightly. The worker then climbs the pre-set ladder to the ventilation pipe on one side, aligns ear plate two with ear plate one, and inserts a pin to secure the mounting bracket. The waste can then be removed from the grating plate through the ventilation pipe. This design allows workers to collect waste more easily and efficiently, demonstrating a user-friendly approach.
