Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a waste gas adsorption treatment device with a multi-layer filter assembly. Background Technology

[0002] In current industrial production, the composition of waste gas is becoming increasingly complex, containing not only soluble gaseous pollutants but also solid particles of different sizes. This places higher demands on the purification efficiency and ease of maintenance of treatment equipment. However, the filtration mechanisms of traditional waste gas treatment devices are mostly fixed integrated structures, with the filter screen and supporting components rigidly connected. They need to be completely disassembled for cleaning, which is not only cumbersome but also makes it impossible to remove a specific layer of filter screen for targeted cleaning. Frequent disassembly and assembly can easily lead to a decrease in the sealing performance of the components.

[0003] In the production process, existing publication number CN211384440U discloses a high-efficiency organic waste gas treatment device, relating to the field of organic waste gas treatment technology. It includes a base, with a settling chamber placed on one side of the top of the base. A pipe is fixedly connected to the upper part of one side of the settling chamber, and a dissolution chamber is fixedly connected to the other end of the pipe. A pipe is fixedly connected to the upper part of the side of the dissolution chamber away from the settling chamber, and a drying chamber is fixedly connected to the other end of the pipe. The drying chamber contains multiple layers of filter screens, with several solid desiccants placed above the filter screens. A support is fixed to the bottom of the drying chamber, and a pipe is fixedly connected to the upper part of the side of the drying chamber away from the dissolution chamber. An adsorption chamber is fixedly connected to the other end of the pipe. Through the coordinated use of the settling chamber, dissolution chamber, and drying chamber, the organic gas is dried and dusted, greatly improving the adsorption effect of the activated carbon in the adsorption chamber. The activated carbon mesh uses a sliding connection for easy replacement of the activated carbon and cleaning of the activated carbon mesh. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Traditional filter components are integrally encapsulated waste gas adsorption treatment devices. When cleaning the filter components, the entire device needs to be disassembled, and it is difficult to process them in layers. This is not only complicated and time-consuming, but also prone to a decrease in structural precision due to repeated disassembly. At the same time, existing waste gas adsorption treatment devices that use a single filtration method either rely solely on liquid adsorption or rely solely on single-layer or ungraded filter filtration, or other waste gas treatment methods. As a result, the treatment effect on waste gases with complex compositions is limited, and it is difficult to achieve comprehensive purification of both soluble components and solid pollutants.

[0005] Therefore, a waste gas adsorption treatment device with a multi-layer filter assembly is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waste gas adsorption treatment device with a multi-layer filter assembly to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste gas adsorption treatment device with a multi-layer filter assembly, comprising a filtration mechanism, a liquid storage assembly, and an air inlet assembly. The filtration mechanism is installed above the liquid storage assembly, and an air inlet assembly is provided on the side of the filtration mechanism. The filtration mechanism includes a support assembly, a filter assembly, and a sealing assembly. The filter assembly is installed on the outer diameter surface of the support assembly, and a sealing assembly is provided above the filter assembly.

[0008] Preferably, the air intake assembly includes an air intake pipe, a solenoid valve, and a connecting pipe, wherein the solenoid valve is installed on the side of the air intake pipe, and the connecting pipe is installed on the side of the solenoid valve away from the air intake pipe.

[0009] Preferably, the liquid storage assembly includes a liquid storage tank, a sealing ring, and a support assembly, wherein the support assembly is mounted on the outer diameter surface of the liquid storage tank, and the sealing ring is mounted on the top of the liquid storage tank.

[0010] Preferably, the bracket assembly includes a fixing ring, a support column, and a support foot, with the support column installed below the fixing ring and the support foot installed below the support column.

[0011] Preferably, the support assembly includes a base, a mounting post, and a limiting piece, with the mounting post mounted above the base and the limiting piece mounted on the outer diameter surface of the mounting post.

[0012] Preferably, the filter assembly includes a filter screen, a limiting ring, and a slider, wherein the limiting ring is installed on the outer diameter surface of the filter screen, and the slider is installed on the outer diameter surface of the limiting ring.

[0013] Preferably, the mounting column is in the form of three stepped columns with different radii, and the lower half of each column has external threads. The mounting column and the limiting piece are connected by threads.

[0014] Preferably, there are three sets of filter screens, which are circular, and there are three sets of limiting rings, which are circular rings with a central through hole. The through holes of the three sets of limiting rings are of different sizes, and the limiting rings and the slider are connected by welding.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this exhaust gas adsorption treatment device with multi-layer filter components forms a sliding connection between the slider on the outer diameter surface of the limiting ring and the slide groove of the liquid storage tank. Combined with the threaded connection structure between the mounting column and the limiting plate, the disassembly process does not require complicated tools. Simply loosen the fixing bolts of the sealing component, remove the sealing rubber sheet, and unscrew the limiting plate to pull out the filter components along the mounting column. The three sets of filter screens can be cleaned separately. This layered and detachable design avoids the cumbersome process of overall disassembly, which not only reduces the time cost of cleaning operations, but also allows for individual treatment of filter screens with different levels of pollution, reducing maintenance difficulty.

[0017] 2. Compared with existing technologies, this waste gas adsorption treatment device with multi-layer filter components significantly improves the waste gas treatment effect through a dual purification mode of liquid adsorption and multi-layer filter filtration. The waste gas first enters the liquid storage component and comes into contact with the liquid in the storage tank. The soluble components are removed by liquid adsorption. Then, it flows upward into the filtration mechanism and achieves graded filtration through three sets of circular filters adapted to different particle sizes, which intercept solid particles of different sizes in sequence. This dual filtration mechanism achieves targeted treatment of soluble components and solid pollutants in the waste gas, avoiding the limitations of a single filtration method.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 4 The exhaust gas adsorption treatment device shown includes a multi-layer filter assembly, a filter mechanism 1, a liquid storage assembly 2, and an air inlet assembly 3. The filter mechanism 1 is installed above the liquid storage assembly 2, and the air inlet assembly 3 is arranged on the side of the filter mechanism 1. The filter mechanism 1 includes a support assembly 4, a filter assembly 5, and a sealing assembly 6. The filter assembly 5 is installed on the outer diameter surface of the support assembly 4, and the sealing assembly 6 is arranged above the filter assembly 5.

[0026] Specifically: When the waste gas adsorption treatment device integrates the liquid storage component 2, the filter mechanism 1 and the air intake component 3 to form a complete waste gas treatment system, the filter mechanism 1 is installed above the liquid storage component 2 to construct the core treatment space. The air intake component 3 is set on the side of the filter mechanism 1 to introduce the waste gas to be treated. Inside the filter mechanism 1, the support component 4 provides installation support for the filter screen component 5, so that the filter screen component 5 can be arranged in an orderly manner to achieve the filtration treatment of waste gas. The sealing component 6 is located above the filter screen component 5. It consists of a sealing rubber sheet and fixing bolts. By covering the support component 4 with the sealing rubber sheet and fixing it to the liquid storage component 2 with the fixing bolts, the sealing performance during the filtration process is ensured.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the air intake assembly 3 includes an air intake pipe 7, a solenoid valve 8, and a connecting pipe 9. The solenoid valve 8 is installed on the side of the air intake pipe 7, and the connecting pipe 9 is installed on the side of the solenoid valve 8 away from the air intake pipe 7. The air intake pipe 7 introduces exhaust gas, and the solenoid valve 8 controls the air intake state by opening and closing. The connecting pipe 9 guides the exhaust gas from the air intake assembly 3 to the bottom of the liquid storage assembly 2, forming a controllable air intake passage.

[0030] In a preferred embodiment, the liquid storage assembly 2 includes a liquid storage tank 10, a sealing ring 11, and a support assembly 12. The support assembly 12 is installed on the outer diameter surface of the liquid storage pipe, and the sealing ring 11 is installed above the liquid storage tank 10. The liquid storage tank 10 stores liquid for adsorbing soluble components in the exhaust gas. The sealing ring 11 prevents exhaust gas leakage at the connection between the liquid storage tank 10 and the air inlet assembly 3. The support assembly 12 provides stable support for the liquid storage tank 10.

[0031] In a preferred embodiment, the support assembly 12 includes a fixing ring 13, a support column 14, and a support foot 15. The support column 14 is installed below the fixing ring 13, and the support foot 15 is installed below the support column 14. The fixing ring 13 fixes the support assembly 12 to the liquid storage tank 10. The support column 14 distributes the weight of the liquid storage tank 10 through vertical support, and the support foot 15 increases the contact area with the ground and reduces the pressure.

[0032] In a preferred embodiment, the support assembly 4 includes a base 16, a mounting post 17, and a limiting piece 18. The mounting post 17 is mounted on the top of the base 16, and the limiting piece 18 is mounted on the outer diameter surface of the mounting post 17. The base 16 supports the mounting post 17 and is fixed above the liquid storage assembly 2. The stepped mounting post 17 provides layered mounting positions for the filter assembly 5. The limiting piece 18 is fixed to the filter assembly 5 by a threaded connection to ensure that the filter screens are arranged in an orderly manner.

[0033] In a preferred embodiment, the filter assembly 5 includes a filter screen 19, a limiting ring 20, and a slider 21. The limiting ring 20 is installed on the outer diameter surface of the filter screen 19, and the slider 21 is installed on the outer diameter surface of the limiting ring 20. The three sets of circular filter screens 19 are positioned by the limiting ring 20. The different through hole sizes of the limiting ring 20 are adapted to the stepped structure of the mounting column 17. The sliding connection between the slider 21 and the slide groove of the liquid storage tank 10 realizes the quick assembly and positioning of the filter assembly 5 and the liquid storage tank 10, and can be quickly removed when the filter assembly 5 needs to be cleaned.

[0034] In a preferred embodiment, the mounting column 17 is a three-section stepped column with different radii. The lower half of each section of the mounting column 17 has external threads on its outer surface. The mounting column 17 and the limiting plate 18 are connected by threads. The three stepped mounting columns 17 with different radii are matched with three sets of limiting rings 20 with different inner diameters to achieve layered independent installation of the filter assembly 5. The threaded connection between the external threads and the limiting plate 18 can accurately fix the axial position of the filter assembly 5 and prevent displacement during filtration.

[0035] In a preferred embodiment, three sets of filter screens 19 are provided, and they are circular filter screens. Three sets of limiting rings 20 are provided, and they are circular rings with a central through hole. The through hole sizes of the three sets of limiting rings 20 are different. The limiting rings 20 and the sliders 21 are connected by welding. The three sets of circular filter screens 19 correspond to pollutants of different particle sizes, so as to achieve graded filtration. The three sets of limiting rings 20 are adapted to the steps of the mounting column 17 through the difference in through hole size, so as to ensure that the filter screens are arranged coaxially. The welded and fixed sliders 21 and limiting rings 20 form an integral whole, ensuring the structural stability during sliding assembly.

[0036] The working process of this utility model is as follows: First, during exhaust gas filtration, exhaust gas is introduced through the intake pipe 7 of the intake assembly 3. After being controlled by the solenoid valve 8, it is guided to the bottom of the liquid storage assembly 2 by the connecting pipe 9. After entering the liquid storage assembly 2, the exhaust gas first comes into contact with the liquid stored in the liquid storage tank 10 that adsorbs soluble gas components, and then flows upward into the filter mechanism 1. It passes through the filter screen assembly 5 fixed by the limiting plate 18 on the mounting column 17 in the support assembly 4 in sequence. The three sets of circular filter screens 19 are positioned on the three stepped columns of the mounting column 17 by the limiting ring 20 to achieve graded filtration. The sealing ring 11 prevents leakage at the connection between the liquid storage tank 10 and the intake assembly 3, while the sealing rubber sheet of the sealing assembly 6 fixes the filter mechanism 1 and the liquid storage assembly 2 by the fixing bolts to ensure the internal sealing of the filter mechanism 1. The liquid storage tank 10 is stably placed on the ground by the fixing ring 13, the support column 14 and the support foot 15 of the bracket assembly 12.

[0037] When the filter screen needs to be cleaned, first loosen the fixing bolts of the sealing assembly 6, remove the sealing rubber sheet, and then use the sliding connection between the slider 21 welded to the outer diameter surface of the limiting ring 20 in the filter screen assembly 5 and the sliding groove of the liquid storage tank 10 to remove the filter screen assembly 5 and the support assembly 4 from the groove of the liquid storage tank 10. Then unscrew the limiting piece 18 on the mounting column 17 and pull all three sets of filter screen assemblies 5 out of the mounting column 17 to clean the filter screen 19. After cleaning, reassemble in reverse order, re-fix the limiting ring 20 through the limiting piece 18, and then use the sealing assembly 6 to fix the filter mechanism 1 and the liquid storage assembly 2 to ensure that the device is restored to a sealed state. The above is the working principle of this waste gas adsorption treatment device with multi-layer filter screen assembly.
