[0002] The activated carbon adsorption device can effectively adsorb organic matter, malodorous gases and other pollutants in the exhaust gas through the large surface area and microporous structure of the activated carbon, improve the purification effect of the exhaust gas, and remove odors, toxic gases and volatile organic compounds in the exhaust gas. Since the activated carbon adsorption is a physical process, it has a regeneration function and can be regenerated by thermal decomposition and recycled. By heating the activated carbon, the impurities adsorbed on its surface and pores are pyrolyzed or desorbed, usually at high temperature, with steam, inert gas or air as the gas medium to release the adsorbed substances from the activated carbon. This process can restore the activated carbon to its original adsorption performance and can be recycled.

After the activated carbon filler layer is regenerated, the activated carbon filler layer is installed on the adsorption device. The process of disassembling and assembling the activated carbon filler layer consumes a lot of time, resulting in a long downtime of the activated carbon adsorption device. Summary of the invention

The wide end of the exchange bucket 22 is connected to the two sides of the installation box 2, and the exchange bucket 22 evenly introduces the exhaust gas into the side of the activated carbon filler layer 9.

[0022] A top cover plate 1 is fixedly provided at the top center position of the installation box 2, an activated carbon filler layer 9 is fixedly provided in the inner cavity of the installation box 2, a U-shaped frame 5 is fixedly provided at the top center position of the top cover plate 1, a central motor 7 is fixedly provided at the top middle position of the U-shaped frame 5, a vertical screw 6 is fixedly provided at the output end of the central motor 7, and the bottom end of the vertical screw 6 is rotatably connected to the top cover plate 1.

[0023] A common rod 4 is threaded into the outer wall of the vertical screw rod 6. Both ends of the common rod 4 are provided with instant regeneration components for instantly regenerating the activated carbon filler layer 9. The instant regeneration components include a guide box 3 and an AC tube 31. The guide box 3 is a hollow box. Both ends of the common rod 4 are fixedly provided with guide boxes 3, and the guide box 3 is movably inserted into the interior of the installation box 2.

[0024] An AC pipe 31 is fixedly installed on the top of the guide box 3, and a sealing component is fixedly installed on the outer wall of the guide box 3 to improve the sealing performance between the guide box 3 and the installation box 2 when the guide box 3 activates the activated carbon filler layer 9. The sealing component includes an auxiliary plate 10 and a sealing ring 81. A top pressure groove 11 is opened at the bottom of the auxiliary plate 10, and a receiving groove 8 is opened on the top cover plate 1 just below the auxiliary plate 10. The vertical height of the guide box 3 is not less than the height of the inner cavity of the installation box 2. AC holes 32 are opened on the opposite surfaces of the two groups of guide boxes 3. The top pressure groove 11 has the same cross-sectional size as the receiving groove 8, and a sealing ring 81 is bonded inside the receiving groove 8.

[0025] It should be added that a one-way valve is provided on the AC pipe 31 so that the hot steam generator can only supply gas to the guide box 3.

[0026] The specific implementation steps and principles of the utility model are as follows:

[0027] When the entire device is working normally, the two sets of guide boxes 3 do not extend into the interior of the installation box 2, and exhaust gas is blown in through the exchange hopper 22 on one side of the installation box 2.
