Description

Technical Field

[0001] This utility model relates to the field of waste acid treatment technology, and in particular to a tail gas absorption device for waste acid treatment. Background Technology

[0002] With the development of industrial environmental protection requirements, in the process of waste acid treatment, it is necessary to efficiently purify and absorb acidic gases and particulate matter in the exhaust gas, which requires the use of absorption devices.

[0003] In practical use, similar absorption devices still have many defects, such as: the filter plates and filter screens of existing absorption devices are prone to clogging due to the accumulation of impurities, requiring frequent manual cleaning; at the same time, the filter plates of existing absorption devices are cumbersome to disassemble and assemble, and their insufficient sealing may lead to exhaust gas leakage. Therefore, it is necessary to design an exhaust gas absorption device for waste acid treatment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tail gas absorption device for waste acid treatment.

[0005] This utility model is achieved using the following technical solution: a waste acid treatment tail gas absorption device, comprising an installation assembly, the installation assembly including a treatment box, a filter screen fixedly connected to the outer surface of the treatment box, and a first treatment chamber and a second treatment chamber formed inside the treatment box by a first partition and a second partition, further comprising:

[0006] The disassembly assembly includes a fixing frame fixedly connected to the outer surface of the processing box, and a filter plate is fixedly connected inside the fixing frame via a fixing seat;

[0007] An absorption assembly, the absorption assembly including a first blade rotatably mounted on top of a second partition, and a second blade rotatably mounted inside the processing chamber.

[0008] As a further improvement to the above solution, the processing box is internally fixedly connected with a first partition and a second partition, and the top of the first partition and the top of the processing box form a first processing cavity.

[0009] The above technical solution divides the interior of the treatment box into a first treatment chamber by the first partition, forming an independent exhaust gas pretreatment space to ensure that the exhaust gas is fully filtered before entering the second treatment chamber.

[0010] As a further improvement to the above solution, the bottom of the second partition and the bottom of the inside of the processing box form a second processing chamber. An air intake motor is fixedly connected to the bottom of the second partition, and a first fan blade is fixedly connected to the output end of the air intake motor.

[0011] Through the above technical solution, the second partition and the bottom of the treatment box form a second treatment chamber for deep absorption and emission of exhaust gas.

[0012] As a further improvement to the above solution, a fixed seat is slidably installed inside the fixed frame, and a damper is fixedly connected to the center of the outer surface of the fixed seat. The side of the damper away from the fixed seat is fixedly connected to the inner wall of the fixed frame, and a handle is fixedly connected to the outer surface of the fixed seat. The handle is slidably installed inside the fixed frame.

[0013] With the above technical solution, the fixed seat is slidably installed in the fixed frame, and with the buffering effect of the damper, it prevents the filter plate from impacting the inner wall of the treatment box due to inertia, thus extending the service life of the equipment.

[0014] As a further improvement to the above solution, a limiting seat is provided on one side of the fixed seat, a sealing plate is fixedly connected to the bottom of the limiting seat, and a filter plate is fixedly connected to one side of the limiting seat. The filter plate is slidably installed inside the processing box.

[0015] Through the above technical solution, the limiting seat, with its inclined surface design, automatically locks its position during filter plate installation, ensuring that the filter plate and the treatment box fit tightly together.

[0016] As a further improvement to the above solution, a control module is fixedly connected to the rear end of the outer surface of the processing box, and a heating tube is fixedly connected to the output end of the control module. The heating tube is located inside the first processing chamber.

[0017] Through the above technical solution, the control module can automatically heat and clean the filter plate and filter screen by adjusting the circuit of the heating tube, thereby reducing manual intervention.

[0018] As a further improvement to the above solution, exhaust motors are fixedly connected to both sides of the outer surface of the processing box, and a second fan blade is fixedly connected to the output end of the exhaust motor. The second fan blade is disposed inside the second processing chamber.

[0019] Through the above technical solution, the exhaust motor drives the second fan blade to rotate, accelerating the discharge of the treated exhaust gas and preventing the gas from lingering in the second treatment chamber.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention uses a control module to regulate the heating element to heat the filter plate and filter screen, promoting the shedding of impurities. The Joule heating effect of the heating element causes the impurities attached to the surface of the filter plate and filter screen to decompose or loosen due to heat, making it easier to clean later. It realizes the intermittent heating function of the heating element to automatically remove the blockages on the filter plate and filter screen, extend the life of the filter components, and reduce the frequency of manual maintenance.

[0022] This invention allows the fixed base to slide within the fixed frame by pulling with a handle, eliminating the limitation of the limit seat on the filter plate. The filter plate then falls and is pulled out due to its own weight. The sliding design of the fixed base makes the disassembly and installation of the filter plate simple and quick, requiring no additional tools. This sliding design, achieved through the disassembly of components, allows the filter plate to be easily pulled out or installed. Combined with the sealing function of the sealing plate, it facilitates maintenance and prevents leakage. The linkage structure of the limit seat and the damper ensures the filter plate is firmly fixed during operation, reducing the risk of equipment failure and protecting operator safety.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5This embodiment of a waste acid treatment tail gas absorption device includes an installation assembly 1, which includes a treatment box 101. A filter screen 102 is fixedly connected to the outer surface of the treatment box 101. The interior of the treatment box 101 is formed with a first treatment chamber 104 and a second treatment chamber 106 through a first partition 103 and a second partition 105. The device also includes:

[0033] Disassembly assembly 2 includes a fixing frame 201 fixedly connected to the outer surface of the processing box 101, and a filter plate 207 is fixedly connected inside the fixing frame 201 via a fixing seat 202;

[0034] The absorption assembly 3 includes a first blade 304 rotatably mounted on the top of the second partition 105, and a second blade 306 rotatably mounted inside the processing box 101.

[0035] The processing box 101 is fixedly connected to a first partition 103 and a second partition 105. The top of the first partition 103 and the top of the interior of the processing box 101 form a first processing cavity 104.

[0036] The bottom of the second partition 105 and the bottom of the inside of the processing box 101 form a second processing cavity 106. An air intake motor 303 is fixedly connected to the bottom of the second partition 105, and a first fan blade 304 is fixedly connected to the output end of the air intake motor 303.

[0037] Driven by the intake motor 303, the first fan blade 304 rotates within the second partition 105. The rotation of the first fan blade 304 generates negative pressure, causing the exhaust gas to be drawn into the first treatment chamber 104 and pass through the filter plate 207 and filter screen 102, where particulate matter and acid mist are initially removed.

[0038] A fixed seat 202 is slidably installed inside the fixed frame 201. A damper 203 is fixedly connected to the center of the outer surface of the fixed seat 202. The side of the damper 203 away from the fixed seat 202 is fixedly connected to the inner wall of the fixed frame 201. A handle 204 is fixedly connected to the outer surface of the fixed seat 202 and is slidably installed inside the fixed frame 201.

[0039] A limiting seat 205 is provided on one side of the fixed seat 202. A sealing plate 206 is fixedly connected to the bottom of the limiting seat 205. A filter plate 207 is fixedly connected to one side of the limiting seat 205. The filter plate 207 is slidably installed inside the processing box 101.

[0040] When the filter plate 207 needs to be disassembled, the handle 204 is pulled to make the fixing seat 202 slide within the fixing frame 201. As the fixing seat 202 continues to slide, the limiting seat 205 will gradually be released. As the limiting seat 205 is released, the filter plate 207 will fall due to its own weight. At this time, the filter plate 207 can be pulled out from the processing box 101, and the filter plate 207 can be replaced or cleaned.

[0041] A control module 301 is fixedly connected to the rear end of the outer surface of the processing box 101. A heating tube 302 is fixedly connected to the output end of the control module 301. The heating tube 302 is located inside the first processing chamber 104.

[0042] The treated exhaust gas is drawn into the second treatment chamber 106 by the second baffle 105, and the second fan blade 306 is driven to rotate by the exhaust motor 305, which can accelerate the gas flow and ensure that the absorbed exhaust gas is quickly discharged from the second treatment chamber 106, avoiding stagnation in the treatment box 101.

[0043] Exhaust motors 305 are fixedly connected to both sides of the outer surface of the processing box 101. A second fan blade 306 is fixedly connected to the output end of the exhaust motor 305. The second fan blade 306 is located inside the second processing chamber 106.

[0044] The implementation principle of the waste acid treatment tail gas absorption device in this embodiment is as follows: The control module 301 consists of a control switch and a power module. After the control module 301 is connected to the power supply, the operator can adjust the control switch to turn the heating tube 302 circuit on or off. When the equipment has been used for a long time, the power module inside the control module 301 processes and converts the input electrical energy to provide the required voltage and current to the heating tube 302. Since the heating tube 302 contains a resistance wire, when the current passes through the resistance wire, the Joule heating effect will be generated due to the resistance, which will raise the temperature of the heating tube 302, thereby heating the filter plate 207 and filter screen 102 in the first processing chamber 104. The heating ensures that the impurities attached to the outer surface of the filter plate 207 and filter screen 102 are removed. After the filter plate 207 is removed and cleaned using the disassembly component 2, the lifespan of the filter screen 102 and filter plate 207 is ensured, realizing automatic heating and cleaning of the filter plate 207 and filter screen 102, reducing manual intervention.

[0045] When the filter plate 207 needs to be disassembled, pull the handle 204 to slide the fixing seat 202 within the fixing frame 201. As the fixing seat 202 continues to slide, the limiting seat 205 will gradually be released. With the limiting seat 205 released, the filter plate 207 will fall due to its own weight. At this time, the filter plate 207 can be pulled out from the processing box 101 for replacement or cleaning. When the filter plate 207 needs to be installed, simply pull the filter plate... 207 slides into the treatment box 101 and is pulled up. As the filter plate 207 rises, the limiting seat 205 slides against the fixed seat 202. When the inclined surface of the limiting seat 205 cancels the contact with the fixed seat 202, the damper 203 resets the fixed seat 202, thereby locking the limiting seat 205 and ensuring that the filter plate 207 is reinstalled in the treatment box 101. The sealing plate 206 can ensure the airtightness of the treatment box 101 and prevent exhaust gas leakage.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
