Thermal gas desorption method based adsorbent regenerating device

Abstract

The invention discloses a thermal gas desorption method based adsorbent regenerating device. The thermal gas desorption method based adsorbent regenerating device comprises an air heater, a desorptiontower, a heat exchanger and a recovery tank which are connected sequentially, wherein an oil gas outlet is formed in the bottom of the desorption tower and is separately connected with a detection pipeline and an oil gas conveying pipe, the detection pipeline is connected with a gas chromatograph, and the oil gas conveying pipe is connected with an inlet end of the heat exchanger; an outlet end of the heat exchanger is connected with an inlet end of the recovery tank through a vacuum pump, and an outlet end of the recovery tank is connected with a drainage pipe through a recovery pump; and the air heater, the desorption tower, the heat exchanger and the recovery tank are separately mounted in four skids, and the skids are detachably connected. The thermal gas desorption method based adsorbent regenerating device is high in environment-friendliness and flexible in use, a desorbing progress of an adsorbent can be monitored in real time, and the problem that energy resources are wasted due to incomplete desorption or excessive desorption does not occur.

Description

technical field [0001] The invention belongs to the technical field of adsorbent regeneration, and in particular relates to an adsorbent regeneration device based on a hot gas desorption method. Background technique [0002] Adsorbent, also known as absorbent, is a solid substance that can effectively absorb certain components from a gas or liquid. The adsorbent has a large specific surface area, suitable pore structure and surface structure; it has a strong adsorption capacity for the adsorbate; it generally does not chemically react with the adsorbate and the medium. Activated carbon is a particle or powder of a porous carbonaceous substance, and it is an excellent adsorbent that was first used and has a wide range of uses. However, the adsorption capacity of activated carbon is limited. To increase the processing capacity of the adsorption device, activated carbon is generally recycled, that is, when the activated carbon reaches saturation or is close to saturation, it i...
