An adsorbent regeneration device based on thermal gas desorption method

Abstract

The invention discloses an adsorbent regeneration device based on a hot gas desorption method, which comprises an air heater, a desorption tower, a heat exchanger and a recovery tank connected in sequence; an oil and gas outlet is arranged at the bottom of the desorption tower, and the oil and gas outlet A detection pipeline and an oil-gas delivery pipe are respectively connected, the detection pipeline is connected with a gas chromatograph, and the oil-gas delivery pipe is connected to the inlet end of the heat exchanger; the outlet end of the heat exchanger is connected to the The inlet end of the recovery tank is connected, and the outlet end of the recovery tank is connected with a discharge pipe through a recovery pump; the air heater, desorption tower, heat exchanger and recovery tank are respectively installed on four skids, and the skids The connection is detachable. The invention has strong environmental protection, flexible use, and can monitor the desorption progress of the adsorbent in real time, without the problem of incomplete desorption or excessive waste of energy due to desorption.

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...
