[0001] The invention relates to the field of activated carbon adsorption boxes, and in particular to a dust waste gas treatment device for chemical production. Background Art

[0002] Activated carbon adsorption box plays an important role in the field of chemical waste gas treatment. It uses the porous structure and huge specific surface area of ​​activated carbon to efficiently remove harmful substances in the waste gas, such as volatile organic compounds, through physical and chemical adsorption, and effectively purifies the air. The equipment has the advantages of environmental protection, energy saving, easy maintenance, strong adaptability, etc., and is suitable for chemical companies of all sizes.

However, there is a problem in the use process. For waste gas with a large amount of dust, it needs to be treated through a waste gas tower, such as a spray tower, to reduce the amount of dust in the waste gas. The activated carbon box itself is difficult to directly treat the waste gas with a certain amount of dust, which undoubtedly reduces the applicability of the activated carbon box to the treatment of waste gas and reduces the convenience of using the activated carbon box.

[0005] Therefore, it is necessary to provide a dust waste gas treatment device for chemical production to solve the above technical problems. Summary of the invention

The filter material 509 is installed on the inner side of the filter frame 508, which realizes the effective treatment of dust exhaust gas. The dust filtering mechanism 5 on the inner side of the pretreatment box 2 is staggered by the first baffle 501, the second baffle 502, and the third baffle 503 to form an "S"-shaped flow channel 504. This structure increases the residence time of the exhaust gas in the flow channel, which is beneficial to the full deposition of dust. At the same time, a number of filter frames 508 and filter materials 509 arranged laterally on the inner side of the flow channel 504 are detachably connected to the baffle through the card slot 507, which not only facilitates the replacement and maintenance of the filter material, but also ensures the high efficiency and stability of the filtering effect, and effectively improves the treatment efficiency of dust exhaust gas.

[0038] like Figure 4 , Figure 6 As shown, a plurality of filter frames 508 are arranged in an equidistant linear arrangement along the height line of the baffle, the filter frames 508 and the flow channel 504 are in a vertical structure, and the airflow passes vertically through the filter frames 508. This layout enables the airflow to be evenly distributed when passing through the dust filter mechanism 5, thereby avoiding the situation where the local filtering load is too large and extending the service life of the filter material. At the same time, the filter frames 508 and the flow channel 504 are in a vertical structure, and the airflow passes vertically through the filter frames 508, which is beneficial to increase the contact area between the airflow and the filter material, improve the filtering efficiency, ensure that the dust exhaust gas can be fully purified, and meet the high requirements of chemical production for exhaust gas treatment.

At the same time, the through holes 604 take into account the uniform distribution of the airflow, avoiding the situation where the local airflow is too large or too small, ensuring the full utilization of the activated carbon, not only improving the exhaust gas treatment effect, but also extending the service life of the activated carbon and reducing the replacement frequency.

[0043] Embodiment 2:

[0044] like Figure 1 , Figure 3As shown, an air outlet 4 is provided on the side of the device body 1 away from the pretreatment box 2, and an air inlet 3 is provided on one side of the pretreatment box 2. Adjustment mechanisms 7 are installed on the outsides of the air inlet 3 and the air outlet 4, so that the treated exhaust gas can be discharged smoothly from the device, avoiding the retention of exhaust gas in the device and secondary pollution.

At the same time, the handles provided on the surface of the movable door make the operation more convenient and safe. This arrangement of the movable door not only improves the maintainability of the device, but also ensures the comfort and efficiency during the operation. In addition, the rotation design of the movable door also takes into account the sealing of the device, avoiding exhaust gas leakage and pollution to the external environment.

[0047] During implementation, the pretreatment box 2 arranged on one side of the device body 1 first performs preliminary treatment on the incoming dust exhaust gas through the dust filter mechanism 5 inside it. The dust filter mechanism 5 is staggered by the first baffle 501, the second baffle 502, and the third baffle 503 to form an "S"-shaped flow channel 504.
