The air inlet guide pipe 5 and the air outlet guide pipe 6 adopt the structure of a circle on a square. The regeneration module comprises a regeneration liquid spraying device located above the shell 4. A recovery bin 7 for collecting the regeneration liquid is installed below the shell 4. The recovery bin 7 and the regeneration liquid spraying device are connected through a circulating pipeline 8. A circulating pump is installed on the circulating pipeline 8. The circulating pump provides power to complete the recycling of the regeneration liquid. The regeneration liquid is used for desorption of the filter device. The filter material can ensure the adsorption efficiency of the filter material through regeneration operation during long-term use, and the operation cost of the adsorption device is reduced.
[0018] The filter device comprises a mounting frame 9. The mounting frame 9 is provided with adsorption filter cartridges 10. The number of the adsorption filter cartridges 10 is multiple, and the adsorption filter cartridges 10 are distributed along the length direction of the mounting frame 9.
[0019] Each adsorption filter cartridge 10 comprises a hollow support frame 11. The side wall of the support frame 11 is paved with fiber filter material 12. The support frame 11 is a hollow design of a cuboid. Five surfaces of the support frame 11 are paved with the fiber filter material 12. One end of the support frame 11 facing the air inlet guide pipe 5 or the air outlet guide pipe 6 is provided with an opening 14.

One end of the filter channel 13 is provided with an opening 14 for gas flow. The directions of the openings 14 on the adjacent two adsorption filter cartridges 10 are opposite. After the multiple adsorption filter cartridges 10 are installed, a continuous S-shaped distribution is formed. Every two adsorption filter cartridges 10 with opposite distribution of the openings 14, when the exhaust gas enters from the opening 14 facing the air inlet guide pipe 5, then flows out from the opening 14 of the other adsorption filter cartridge 10 facing the air outlet guide pipe 6 after passing through two layers of filter material. The design makes the exhaust gas at least pass through two layers of fiber filter material 12 during the flow process, which can improve the purification effect in advance.

The regeneration liquid is transported into the liquid storage tank 17 through the circulating pipeline 8, and then falls onto the filter device through the discharging holes 18 to perform desorption operation on the fiber filter material 12.
[0022] The working principle / assembly process of the scheme: first, make the adsorption filter element 10, lay the fiber filter material 12 on the four side walls of the cuboid support frame 11, then seal one end face and reserve the opening 14 on the other end face, then insert the plurality of adsorption filter elements 10 into the mounting frame 9 in the opposite way of the opening 14 to form a filter device, place the filter device in the shell 4, connect the air inlet guide pipe 5 and the air outlet guide pipe 6 at both ends of the shell 4, install the recovery bin 7 below the shell 4 and the spraying device above the shell 4, adsorb the acidic or alkaline gas in the waste gas when the waste gas passes through the filter device, then perform desorption operation by using the regeneration liquid at regular time, so as to avoid the decline of the adsorption capacity of the fiber filter material 12 in a long time use.
