Description

Technical Field

[0001] The utility model relates to the technical field of resin adsorption towers, in particular to a Voc resin tail gas adsorption and desorption tower. Background Art

[0002] A resin adsorption tower is a device used to separate and purify substances in gas or liquid. It usually consists of a cylindrical container and a filler, where the filler is made of resin particles. Separation is achieved through the adsorption of the target substance by the resin. This equipment is widely used in chemical, environmental protection and petroleum industries.

[0003] The adsorption process of the resin adsorption tower: the organic waste gas passes through the resin layer, and the porous structure and strong adsorption performance of the resin are used to adsorb the organic pollutants in the waste gas on the resin surface. The desorption process: the organic pollutants adsorbed on the resin surface are released through hot steam or organic solvent flushing to achieve the regeneration and reuse of the resin.

[0004] However, the existing resin adsorption tower needs to be connected to external equipment to allow hot steam to enter the tower and to facilitate cooling water to enter the tower. It does not have a structure for supplying hot steam and cooling water. Therefore, a Voc resin tail gas adsorption and desorption tower is proposed. Through the arrangement of a chiller, a steam generator and a heating component, cooling water can be supplied to the box body and hot steam can be supplied to the tower body. Utility Model Content
