Abstract

The invention belongs to the field of adsorbers and particularly relates to a heating and vacuum desorption combined adsorber and an adsorption and desorption method and application. The adsorber adopts a vertical radial-flow adsorber structure, and heat exchange tubes are arranged vertically so as to make full use of the height space, reduce occupied area, enhance heat exchange and uniformity andimprove operation compatibility to a vacuumizing desorption mode. The adsorber realizes regeneration of an adsorption material in an indirect heating and vacuum desorption combined regeneration mode.The adsorber easily realizes fast heating and vacuum regeneration functions and has advantages of high heat exchange efficiency, small occupied area, short regeneration time of the adsorption material, high flow field uniformity and the like.

Description

technical field [0001] The invention belongs to the field of adsorbers, and in particular relates to an adsorber combining heating and vacuum desorption, an adsorption and desorption method and its application; the adsorber can realize the combination of tube-and-tube indirect heating and vacuum desorption after adsorption of an adsorption material. Background technique [0002] Fixed-bed adsorbers based on adsorption are widely used in gas separation. During the adsorption process, the mixed components pass through the bed of the adsorbent material, the light component gas is not or less adsorbed and penetrates the fixed bed earlier, and the heavy component gas is mainly adsorbed until the adsorbent material is saturated, which can be recovered during the regeneration process of the adsorbent material Heavy component gas, so as to realize the separation of light and heavy component gas. Based on the above process, many gases with high resource value in industrial tail gas ...
