Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device for activated carbon adsorption. Background Technology

[0002] Activated carbon adsorption waste gas treatment device is a device that uses the adsorption properties of activated carbon to purify waste gas. The device mainly consists of activated carbon adsorbent, adsorption bed, waste gas inlet, purified gas outlet, and related pipelines and control system. Its working principle is that waste gas containing pollutants enters the device through the inlet and comes into full contact with the activated carbon in the adsorption bed. Activated carbon, with its huge specific surface area and porous structure, adsorbs organic pollutants and odor substances in the waste gas onto its surface, thereby purifying the gas and discharging it from the outlet. This achieves effective treatment of waste gas, meets environmental emission standards, and reduces the pollution of the environment by waste gas.

[0003] Existing activated carbon adsorption devices use a drawer-type structure. Although this structure makes it easy to replace the adsorption layer, it also has the disadvantage of poor sealing, which can easily lead to the leakage of harmful gases. At the same time, some of the gases being processed contain moisture, which can affect the adsorption capacity of activated carbon.

[0004] An existing patent (publication number: CN212142036U) discloses an activated carbon adsorption device for waste gas treatment, comprising a main body, with an air inlet and an air outlet respectively provided at both ends of the main body. Inside the main body, a pull-out drying layer and a pull-out adsorption layer are fixedly provided at the air inlet end. The pull-out adsorption layer includes a first pull-out adsorption layer and a second pull-out adsorption layer. This utility model is an activated carbon adsorption device for waste gas treatment with the above-mentioned structure. It has a simple structure, reliable sealing, and convenient operation. The presence of a pull-out drying layer and two pull-out adsorption layers makes the adsorption effect better.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing waste gas treatment devices for activated carbon adsorption often suffer from uneven airflow distribution after the waste gas enters the adsorption structure. This results in insufficient contact between the waste gas and the activated carbon, leading to low adsorption efficiency and difficulty in ensuring high-efficiency waste gas treatment. Furthermore, particulate matter and impurities carried in the waste gas can easily enter the adsorption structure, clogging the pores of the activated carbon, reducing its adsorption performance, shortening its lifespan, and increasing equipment maintenance costs.

[0006] Therefore, a waste gas treatment device for activated carbon adsorption is proposed. Utility Model Content

This leads to insufficient contact between the waste gas and activated carbon, resulting in low adsorption efficiency and difficulty in ensuring high-efficiency waste gas treatment. Furthermore, particulate matter and impurities carried in the waste gas can easily enter the adsorption structure, clogging the pores of the activated carbon, reducing its adsorption performance, shortening its service life, and increasing the maintenance cost of the equipment.

The side of the locking block closest to the flow guiding plate is bolted to the flow guiding plate, and the surface of the locking block is locked to the inner wall of the adsorption structure. The right side of the flow guiding plate is bolted to the left side of the flow guiding cylinder.

[0028] Please see Figure 1-6The present invention provides the following technical solution:

[0029] A waste gas treatment device for activated carbon adsorption includes an adsorption structure 1, a flow guiding mechanism 2 is snapped into the inner wall of the adsorption structure 1, a pretreatment box 4 is fixedly connected to the left side of the adsorption structure 1, a filter frame 5 is provided on the inner wall of the pretreatment box 4, and a filter assembly 3 is inserted into the inner wall of the filter frame 5.

[0030] The flow guiding mechanism 2 includes a flow guiding cylinder 201, a flow guiding plate 202, and a locking block 203. The side of the locking block 203 near the flow guiding plate 202 is bolted to the flow guiding plate 202, and the surface of the locking block 203 is locked to the inner wall of the adsorption structure 1. The right side of the flow guiding plate 202 is bolted to the left side of the flow guiding cylinder 201.

[0031] In this embodiment: By setting a flow guiding mechanism 2, which is engaged with the inner wall of the adsorption structure 1 by a locking block 203 during use, the flow guiding mechanism 2 can be securely installed. The flow guiding plate 202 and the flow guiding cylinder 201 cooperate to guide the waste gas entering the adsorption structure 1 to be evenly distributed, avoiding uneven airflow at the air inlet of the adsorption structure 1, so that the waste gas can have more full contact with the activated carbon, effectively improving the adsorption efficiency of the activated carbon for pollutants in the waste gas, and ensuring the stability and high efficiency of the waste gas treatment effect. By setting a pretreatment box 4 and a filter frame 5, and inserting a filter assembly 3 into the inner wall of the pretreatment box 4, the waste gas can be pretreated before entering the adsorption structure 1. The filter assembly 3 can effectively intercept particulate matter and impurities in the waste gas, preventing these substances from entering the adsorption structure 1 and clogging the pores of the activated carbon, reducing the adsorption performance of the activated carbon, and extending the service life of the activated carbon.

[0032] Specifically, such as Figure 5 As shown, the filter assembly 3 includes a connecting frame 301 and a filter screen 302. The surface of the filter screen 302 is fixedly connected to the inner wall of the connecting frame 301, and the surface of the connecting frame 301 is inserted into the inner wall of the filter frame 5.

[0033] Specifically, such as Figure 5 As shown, the inner wall of the filter frame 5 is provided with an installation groove 6 that is used in conjunction with the connecting frame 301, and the inner wall of the filter frame 5 is provided with an air inlet 7.

[0034] Specifically, such as Figure 3 As shown, a mounting plate 8 is bolted to the front side of the filter frame 5, and the surface of the mounting plate 8 is engaged with the inner wall of the pretreatment box 4.

[0035] In this embodiment: by setting up a connecting frame 301 and a filter screen 302, it is convenient to drive the filter screen 302 to perform pre-filtration work through the connecting frame 301. The mounting groove 6 opened in the inner wall of the filter frame 5 makes it convenient for the connecting frame 301 to be installed in the inner wall of the filter frame 5 through the mounting groove 6. The air inlet 7 opened in the inner wall of the filter frame 5 makes it convenient for exhaust gas to enter the inner wall of the filter frame 5 through the air inlet 7. By setting up a mounting plate 8, the position of the mounting plate 8 and the filter frame 5 is fixed during use, which facilitates the subsequent stable installation of the filter frame 5.

[0036] Specifically, such as Figure 3 As shown, a sealing ring 9 is bonded to the inner wall of the mounting plate 8, and the surface of the sealing ring 9 is engaged with the inner wall of the pretreatment box 4.

[0037] Specifically, such as Figure 4 As shown, the inner wall of the pretreatment box 4 is provided with a sealing groove 10 that is used in conjunction with the sealing ring 9, and the inner wall of the pretreatment box 4 is provided with a connecting groove 11 that is used in conjunction with the filter frame 5.

[0038] In this embodiment: by setting a sealing ring 9, the sealing ring 9 is moved by the mounting plate 8 during use, so that the surface of the sealing ring 9 is engaged with the inner wall of the filter frame 5, which facilitates the sealing work and avoids the leakage of exhaust gas. The sealing groove 10 opened in the inner wall of the pretreatment box 4 facilitates the installation of the sealing ring 9 on the inner wall of the filter frame 5 through the sealing groove 10. The connecting groove 11 opened in the inner wall of the pretreatment box 4 facilitates the installation of the filter frame 5 on the inner wall of the pretreatment box 4 through the connecting groove 11.

[0039] Specifically, such as Figure 6 As shown, a limiting block 12 is provided on the front side of the pretreatment box 4, and a limiting frame 13 is bolted to the front side of the mounting plate 8. The surface of the limiting block 12 is engaged with the inner wall of the limiting frame 13.

[0040] Specifically, such as Figure 2 As shown, a pull rod 14 is bolted to the left side of the locking block 203, and a positioning groove 15 is provided on the inner wall of the adsorption structure 1 to cooperate with the locking block 203.

[0041] In this embodiment: the limiting block 12 set on the front side of the pretreatment box 4 is engaged with the limiting frame 13 bolted to the front side of the mounting plate 8, which can limit the position of the mounting plate 8 and the filter frame 5, prevent them from shifting during use, and ensure the stable operation of the filter assembly 3. The pull rod 14 bolted to the left side of the locking block 203 cooperates with the positioning groove 15 on the inner wall of the adsorption structure 1, which makes it easy for operators to insert and remove the flow guiding mechanism 2, and facilitates the inspection, maintenance and replacement of the flow guiding mechanism 2, ensuring that the flow guiding mechanism 2 effectively guides the uniform distribution of exhaust gas for a long time and improves the exhaust gas treatment effect.

[0042] Working principle: During the use of adsorption structure 1, a flow guiding mechanism 2 is set up. During use, the mechanism is locked to the inner wall of adsorption structure 1 by a locking block 203, which can securely install the flow guiding mechanism 2. The flow guiding plate 202 and the flow guiding cylinder 201 cooperate to guide the waste gas entering adsorption structure 1 to be evenly distributed, avoiding uneven airflow at the air inlet of adsorption structure 1. This allows the waste gas to have more full contact with activated carbon, effectively improving the adsorption efficiency of activated carbon for pollutants in waste gas and ensuring the stability and high efficiency of waste gas treatment. By setting up a pretreatment box 4 and a filter frame 5, and inserting a filter assembly 3 into the inner wall of the pretreatment box 4, the waste gas can be pretreated before entering adsorption structure 1. The filter assembly 3 can effectively intercept particulate matter and impurities in the waste gas, preventing these substances from entering adsorption structure 1 and clogging the pores of activated carbon, reducing the adsorption performance of activated carbon, and extending the service life of activated carbon.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
