[0002] As an indispensable important equipment in industrial production process, the type and performance of waste gas adsorber are directly related to the efficiency and effect of waste gas treatment. Among many waste gas adsorbers, box adsorption structure is favored due to its unique advantages. The waste gas adsorber with box adsorption structure is mainly composed of a box, a filter element and related connecting and supporting components. The significant feature of this structure is that it can accommodate a large volume of filter element inside, thereby providing greater waste gas treatment capacity and higher filtration efficiency. The filter element usually adopts high-efficiency adsorption materials such as activated carbon, molecular sieve, etc. to effectively adsorb harmful substances in waste gas, achieving the purpose of purifying waste gas.

[0003] In order to facilitate the replacement of the filter element, the box adsorption structure adopts a pull-out design. This design makes the replacement process of the filter element more convenient and quick, reduces maintenance costs and improves the operating efficiency of the equipment. At the same time, the pull-out design also facilitates the cleaning and regeneration of the filter element, prolonging the service life of the filter element.

[0004] However, although the waste gas adsorber with box adsorption structure has achieved good results in practical application, it still has some shortcomings. Since the filter element cannot be maintained after being pulled out, it is necessary to stop work to replace the filter element. On the other hand, since the filter element is distributed inside the box, it is not possible to cancel the filtration function or to make a specified filter element perform filtration. SUMMARY

[0024] A waste gas adsorber comprises a waste gas adsorber shell;

[0025] For example, Figures 1 to 3 The waste gas adsorber shell comprises a rectangular wall body and a front-rear-through shell 1. The left end of the shell 1 is provided with a front opening 2. The right end of the shell 1 is provided with a rear opening 3 located at the rear side of the front opening 2. The shell 1 is fixedly connected with a front partition 5 and a rear partition 7. The shell 1 is rotatably connected with a front rotating door 6 and a rear rotating door 8. The front part of the front rotating door 6 and the rear rotating door 8 is fixedly connected with a shaft structure, so that the shaft structure is rotatably connected to the bottom of the shell 1. The rear part of the front rotating door 6 and the rear rotating door 8 is fixedly connected with a flexible rubber arc convex part, which is used to fit with the inner wall of the shell 1. The flexible rubber arc convex part of the front rotating door 6 can also fit with the front end of the rear partition 7.

[0026] Further, the front partition 5, the front rotating door 6, the rear partition 7 and the rear rotating door 8 coincide to form a complete partition, which divides the inside of the shell 1 into two air passages, one on the left and one on the right. The front partition 5, the front rotating door 6, the rear partition 7 and the rear rotating door 8 are distributed in order from front to back.

[0027] The front rotating door 6 and the rear rotating door 8 can be fitted with the left end of the inner wall of the shell 1 by rotating 90° clockwise.
