A regeneration apparatus for renewable adsorbent

The utility model provides a regeneration device for a renewable adsorbent. A plurality of straight pipes are adopted to replace a coil pipe, no welding seam exists in a shell of the regeneration device, the reliability of the whole regeneration device is greatly enhanced, if a single straight pipe has a leakage point, the heat exchange pipe can be blocked by a blind plate, and the other straightpipes can still be used continuously; furthermore, in the case of a regeneration device housing of the same size, compared with the traditional regeneration device, the regeneration device provided bythe utility model has the advantages that the operation is simple; according to the regeneration device provided by the utility model, the plurality of metal fins are arranged on the outer wall of the straight pipe, so that the metal fins are tightly attached to the adsorbent, the heat is more easily transferred to the adsorbent from the straight pipe through the metal fins, the heat exchange effect is greatly improved, a
