Monomer adsorption rotating tower

Abstract

The invention discloses a monomer adsorption rotating tower, which comprises an adsorption tower, wherein an adsorption body divided into a plurality of small adsorption units and a valve body are arranged in the adsorption tower; at least one of the valve body and the adsorption body configured to be of a movable structure, wherein tracks of the valve body and the adsorption body intersect, and the valve body seals the small adsorption units at the track intersection in a polling mode; and a desorption device used for conveying a desorption medium into the valve body. Compared with the prior art, the rotating tower has the beneficial effects that a traditional integrated adsorption body is arranged to be of a split structure, the valve body for sealing all the split bodies in a polling mode is arranged, during adsorption operation, the valve body seals the split bodies in a circulating mode, then a medium input by a desorption device is guided in, and then the split bodies can be subjected to desorption operation; the whole device can continuously perform adsorption operation, and the situation that the whole adsorption body is saturated is avoided.

Large volume of adsorption materials 2. Equipment 3. High cost of material replacement and hazardous waste treatment 4. High equipment manufacturing consumables 5. Large equipment footprint 6. Large heat loss 7. Time-consuming replacement of adsorption materials 8. High-boiling organic matter adsorbed on activated carbon It is difficult to desorb 9. The adsorption performance of activated carbon changes with the running time. 10. The service life of activated carbon is short, generally 1-1.5 years and needs to be replaced as a whole; the main problems of the concentration runner treatment equipment are: 1. Adsorption transfer The wheel is an integral module and is easy to block. Once the molecular sieve air hole is blocked and cannot be cleaned, it needs to be replaced as a whole. 2. The replacement cost of the adsorption wheel is high and the cycle is long. 3. Disadvantages such as high investment cost of one-time equipment
