[0012] 2) Install an infrared heating device below each adsorption bed to dry the adsorbent in the adsorption layer, thereby ensuring the catalytic activity of the adsorbent.

[0013] 3) Since roller tracks are installed below both the first bed frame and the second bed frame, and maintenance doors are provided on the wall of the tower body at positions corresponding to the drying bed and each adsorption bed, only by opening the maintenance door can the bed frame be pulled out from the corresponding maintenance door to realize the replacement of the packing in the drying layer or the adsorption layer, and the operation is simple and convenient.

[0014] 4) The positioning frame arranged in the filter box can position each group of filter cotton. Only by uncovering the box cover and pulling out the filter cotton upward can it be replaced, and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
