Abstract

The invention discloses a conversion type adsorption and desorption device and a method thereof, and belongs to the technical field of resin adsorption. The device comprises an adsorption tower and a desorption tower, wherein the adsorption tower is arranged above the desorption tower, the bottom of the adsorption tower and the top of the desorption tower are correspondingly arranged, a partition plate allowing a resin to pass through is arranged between the adsorption tower and the desorption tower, an adsorption water inlet channel, an adsorption layer and an adsorption water outlet channel are sequentially arranged in the adsorption tower in the direction from bottom to top, a desorption liquid inlet channel, a desorption layer and a desorption liquid outlet channel are sequentially arranged in the desorption tower from top to bottom, and the sizes of the cross sectional areas of the adsorption layer and the desorption layer are specifically set. According to the invention, the adsorption and desorption efficiency and the cyclic utilization rate of the resin can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of resin adsorption, and more specifically relates to a conversion adsorption-desorption device and a method thereof. Background technique [0002] At present, the wastewater adsorption device usually adopts the traditional fixed bed adsorber, and generally adopts the upper and lower equal diameter adsorbers, and the resin bed is fixed, and the adsorption and desorption cannot be well adapted to the different saturation states inside the resin layer, that is, the pollutants are different during adsorption. The state of concentration will cause the imbalance of adsorption and desorption, and the role of resin adsorption and desorption cannot be fully exerted. [0003] After searching, the patent CN201809203U discloses a device for resin adsorption wastewater treatment and steam desorption regeneration. By setting a resin tower equipped with adsorption resin, a tail gas distributor, a steam trap, a condenser a...
