Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to a sulfuric acid exhaust gas treatment and degradation spray device. Background Technology

[0002] Sulfuric acid tail gas refers to waste gas containing sulfuric acid or its acidic components generated during industrial production processes, especially in the chemical, metallurgical, and power industries. Because the sulfuric acid component in sulfuric acid tail gas is highly corrosive and acidic, direct emission will cause serious pollution to the atmospheric environment, water bodies, and soil, and pose a threat to human health. Therefore, sulfuric acid tail gas treatment and degradation spraying devices are needed to bring the tail gas into contact with a specific absorbent liquid, so that the sulfuric acid component in the tail gas reacts with the absorbent liquid, degrading and removing harmful substances, and ultimately achieving the purpose of purifying the waste gas.

[0003] Currently, there are various types of sulfuric acid tail gas treatment and degradation spray devices on the market. However, during long-term operation, the filters inside these devices often accumulate a large amount of impurities, causing blockage on their surface and affecting the filtration effect. Operators usually need to perform tedious manual operations to disassemble and clean the filters. The entire operation is laborious and time-consuming, increasing the difficulty of operation and extending downtime. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sulfuric acid tail gas treatment and degradation spray device.

[0005] This utility model is achieved by the following technical solution: a sulfuric acid tail gas treatment and degradation spraying device, including a limiting mechanism, a protective mechanism and a body, wherein the limiting mechanism is located inside the protective mechanism and the body is located at the upper end of the limiting mechanism;

[0006] The limiting mechanism includes a limiting plate, a limiting ring slidably connected to the inner wall of the limiting plate, a connecting post fixedly connected to the front end of the limiting ring, a sliding groove provided on the outer side of the limiting plate, a limiting block slidably connected to the inner wall of the sliding groove, a connecting plate fixedly connected to the front end of the limiting block, a moving plate fixedly connected to the front end of the connecting plate, an auxiliary plate rotatably connected to the inner wall of the moving plate, a fixed plate slidably connected to the surface of the moving plate, a support plate fixedly connected to the surface of the moving plate, and a spring fixedly connected to the bottom of the support plate.

[0007] Through the above technical solution, the rotating limiting ring can effectively limit the limiting plate, while the sliding limiting block can further precisely limit the limiting ring, thereby effectively preventing the limiting ring from loosening during the operation of the device and ensuring the overall stability of operation.

[0008] As a further improvement to the above scheme, the number of the limiting rings is set to two, and the two limiting rings are symmetrically distributed on the left and right sides with the limiting plate as the center.

[0009] The above technical solution improves the stability of the overall structure by symmetrically arranged limiting rings, thereby further ensuring the stable operation of the device.

[0010] As a further improvement to the above solution, the support plate is located on both sides of the movable plate, and the spring is located inside the fixed plate.

[0011] As a further improvement to the above solution, the protective mechanism includes a housing, a protective frame slidably connected to the inner wall of the housing, a filter screen fixedly connected to the inner wall of the protective frame, and a baffle rotatably connected to the inner wall of the front end of the housing.

[0012] Through the above technical solutions, the filter screen can efficiently intercept particulate matter in waste liquid, which helps to reduce the interference of impurities on subsequent treatment processes.

[0013] As a further improvement to the above solution, the limiting plate is fixedly connected to the front end of the protective frame, the fixing plate is fixedly connected to the front end of the housing, and the sliding groove is formed on the inner wall of the housing.

[0014] As a further improvement to the above solution, the machine body includes an outer shell, a spray tower is fixedly connected to the inner wall of the outer shell, an air inlet is fixedly connected to one side of the outer shell, an air outlet is fixedly connected to the top of the outer shell, a water inlet is fixedly connected to the other side of the outer shell, and a material outlet is fixedly connected to one side of the shell.

[0015] Through the above technical solutions, the exhaust port can ensure that the treated exhaust gas can be discharged in a timely manner, while the adjustment of the air inlet and water inlet can ensure that the liquid and gas in the spray tower are in full contact, thus optimizing the treatment effect.

[0016] As a further improvement to the above solution, the discharge port is located at the lower end of the water inlet, and the spray tower is located at the upper end of the protective frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a limiting mechanism. The operator slides the movable plate inside the fixed plate downwards, causing the supporting plate to move downwards as well, thus compressing the spring. During the downward movement of the movable plate, the auxiliary plate engages with a groove on the fixed plate via a protruding block, ensuring the movable plate remains at the bottom of the fixed plate. The connecting plate slides with the movable plate, moving the limiting block towards the bottom of the groove, thus removing the limiting ring. The connecting column then rotates the limiting ring 180° to separate it from the limiting plate, allowing the limiting plate to be removed. The entire operation is convenient and quick, allowing the operator to easily remove the filter for cleaning. This reduces operational difficulty and further ensures the overall stability of the device during operation.

[0019] This invention features a machine body that introduces the sulfuric acid tail gas to be treated into a spray tower through an air inlet and sends liquid into the spray tower through a water inlet, thereby degrading the harmful components in the tail gas. The treated tail gas is discharged through an air outlet, and the waste liquid is discharged through a discharge outlet to enter the subsequent waste liquid treatment stage. The whole process is simple and efficient, and can effectively treat sulfuric acid tail gas. Attached Figure Description

[0029] 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. Example

[0030] Please combine Figure 1-7 The sulfuric acid tail gas treatment and degradation spraying device of this embodiment includes a limiting mechanism 1, a protective mechanism 2 and a body 3. The limiting mechanism 1 is located inside the protective mechanism 2 and the body 3 is located at the upper end of the limiting mechanism 1.

[0031] The limiting mechanism 1 includes a limiting plate 11, a limiting ring 12 slidably connected to the inner wall of the limiting plate 11, a connecting post 13 fixedly connected to the front end of the limiting ring 12, a sliding groove 14 provided on the outer side of the limiting plate 11, a limiting block 15 slidably connected to the inner wall of the sliding groove 14, a connecting plate 16 fixedly connected to the front end of the limiting block 15, a moving plate 17 fixedly connected to the front end of the connecting plate 16, an auxiliary plate 18 rotatably connected to the inner wall of the moving plate 17, a fixed plate 19 slidably connected to the surface of the moving plate 17, a support plate 191 fixedly connected to the surface of the moving plate 17, and a spring 192 fixedly connected to the bottom of the support plate 191. Rotating the limiting ring 12 can effectively limit the limiting plate 11, while sliding the limiting block 15 can further precisely limit the limiting ring 12, thereby effectively preventing the limiting ring 12 from loosening during the operation of the device and ensuring the overall stability of the operation.

[0032] The number of limiting rings 12 is set to two. The two limiting rings 12 are symmetrically distributed on the left and right sides with the limiting plate 11 as the center. The symmetrically arranged limiting rings 12 can improve the stability of the overall structure, thereby further ensuring that the device can operate stably.

[0033] Support plates 191 are located on both sides of movable plate 17, and springs 192 are located inside fixed plate 19.

[0034] The protective mechanism 2 includes a housing 21, a protective frame 22 is slidably connected to the inner wall of the housing 21, a filter screen 23 is fixedly connected to the inner wall of the protective frame 22, and a baffle 24 is rotatably connected to the inner wall at the front end of the housing 21. The filter screen 23 can efficiently intercept particulate matter in the waste liquid, which helps to reduce the interference of impurities on the subsequent treatment process.

[0035] The limiting plate 11 is fixedly connected to the front end of the protective frame 22, the fixing plate 19 is fixedly connected to the front end of the housing 21, and the sliding groove 14 is formed on the inner wall of the housing 21.

[0036] The body 3 includes an outer shell 31, a spray tower 32 is fixedly connected to the inner wall of the outer shell 31, an air inlet 33 is fixedly connected to one side of the outer shell 31, an air outlet 34 is fixedly connected to the top of the outer shell 31, a water inlet 35 is fixedly connected to the other side of the outer shell 31, and a discharge outlet 36 is fixedly connected to one side of the shell 21. The air outlet 34 can ensure that the treated exhaust gas can be discharged in time. At the same time, by adjusting the air inlet 33 and the water inlet 35, the liquid and gas in the spray tower 32 can be fully contacted to optimize the treatment effect.

[0037] The discharge port 36 is located at the lower end of the water inlet 35, and the spray tower 32 is located at the upper end of the protective frame 22.

[0038] The implementation principle of the sulfuric acid tail gas treatment and degradation spray device in this application embodiment is as follows: the sulfuric acid tail gas to be treated is transported from the inlet 33 to the inside of the spray tower 32, and then liquid is transported into the inside of the spray tower 32 through the water inlet 35 to spray the tail gas inside. The treated tail gas can finally be discharged through the outlet 34. The waste liquid generated by spraying the tail gas inside the spray tower 32 will fall from the bottom of the shell 31 through the filter screen 23 into the waste liquid tank inside the shell 21. The filter screen 23 can block larger particles in the waste liquid, thereby facilitating the further treatment of the waste liquid. The waste liquid inside is eventually transported out from the discharge port 36. When the filter screen 23 needs to be cleaned, the operator opens the baffle 24 and then slides the moving plate 17 downward. The moving plate 17 can drive the support plate 191 to move downward together. At this time, the support plate 191 will compress the spring 192 to retract it. When the moving plate 17 is about to slide to the bottom of the fixed plate 19, the operator pulls out the auxiliary plate 18 inside the moving plate 17, so that the auxiliary plate 18 limits the fixed plate 19. The protrusion on the auxiliary plate 18 can engage with the groove on the fixed plate 19 to... This ensures that the movable plate 17 can remain stably at the bottom of the fixed plate 19. The movable plate 17 can drive the connecting plate 16 to slide together, thereby allowing the connecting plate 16 to drive the limiting block 15 to slide to the bottom of the slide groove 14. At this time, the slide groove 14 can release the limiting ring 12. Then, the operator can rotate the connecting column 13 outward by 180°. The connecting column 13 can drive the limiting ring 12 to rotate together, thereby releasing the limiting ring 12 from the limiting plate 11. The operator can then pull out the limiting plate 11 to remove the filter screen 23 on the protective frame 22 for cleaning. After cleaning, the operator pushes the protective frame 22 back into the housing 21, then rotates the connecting column 13 in the opposite direction to allow the limiting ring 12 to limit the limiting plate 11 again. Then, the auxiliary plate 18 on the fixed plate 19 is removed and pushed back into the moving plate 17. At this time, the spring 192 loses its compressive force and pushes the support plate 191, thereby driving the connecting plate 16 to move upward together, so that the limiting block 15 can limit the limiting ring 12 again. The whole operation process is convenient and quick, and can also further ensure the overall stability of the device during operation.

[0039] 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.
