[0002] In the technical field of activated carbon waste gas treatment, in order to remove various pollutants such as toxic substances contained in the waste gas, it is necessary to use various media for adsorption, elimination and other filtration treatments. The general structure is to install the filter media in sequence inside the activated carbon waste gas treatment device. Let the exhaust gas pass through the multi-layer filter media in turn. After a period of use, harmful substances will be absorbed and accumulated on the filter media. Therefore, it is necessary to maintain and clean the media in time to make it function again. The common solution is to filter After the medium is removed, it is cleaned, maintained, or replaced, but this solution is time-consuming and labor-intensive, which is not conducive to improving the efficiency of activated carbon exhaust gas treatment

Another solution is to pass catalytic reduction gas into the filter chamber, and use catalytic reduction gas to process the medium. This treatment method does not need to disassemble and replace the filter medium, and the workload is small and the efficiency is high. However, the filter device needs to be suspended during the process. In some cases, for example, when the concentration of gas pollutants is high, the filter media near the air inlet may quickly reach the adsorption limit and need to be cleaned and maintained, while the subsequent filter media still have high adsorption capacity, but in order to ensure The effectiveness of the entire adsorption device still needs to suspend the entire equipment for cleaning and maintenance. This process leads to a waste of adsorption resources, reduces the overall performance of the adsorption device, and increases the frequency of cleaning and maintenance, especially in large or high-frequency activated carbon. During the process of waste gas treatment project, it will greatly affect the efficiency of the whole waste gas treatment

[0003] On the other hand, the existing exhaust gas treatment equipment needs to be equipped with various functional pipes including inlet pipes, outlet pipes, and catalytic pipes, resulting in the need to connect many pipes in addition to the cabinet or tower structure during equipment installation. like Figure 5 As shown, it includes at least the main air intake pipe 7a, the main air outlet pipe 7b, the branch pipe 7e and the catalytic air intake pipe 7c, the catalytic air intake pipe outlet pipe 7d, and the catalytic pipe branch pipe 7f. Each pipe needs to be connected independently with each box through the branch pipes , the staggered layout of the pipelines is dazzling, and the installation design and maintenance of each pipeline lead to a high cost of installation and use of exhaust gas treatment equipment

At the same time, corresponding solenoid valves need to be configured between various types of pipelines and filter boxes or filter chambers to control the opening and closing of each pipeline. Even the simplest catalytic reduction task requires at least 3 to 6 valves to control the action and complete it. , when the volume of the catalytic equipment expands and the processing area becomes larger and larger, the corresponding valves will also increase rapidly, resulting in a sharp increase in the control program and the amount of valve action required when the entire equipment is in use. On the one hand, the operation is more difficult, and the operator And the requirements for the operating system are higher, and the probability of problems will increase immediately, and the stability and effectiveness of the exhaust gas treatment device will be greatly reduced, which is not conducive to the continuous and stable process of the treatment program.
