Radial tubular absorber and absorption and desorption method thereof

Abstract

The invention belongs to the field of absorbers and in particular relates to a radial tubular absorber and an absorption and desorption method thereof. The radial tubular absorber comprises an absorber shell, a middle shell layer, an outer flow channel, a central flow channel, a powder collection groove and an absorption pipe, wherein a fluid inlet end and a fluid outlet end are arranged at two ends of the absorber shell respectively; the middle shell layer is arranged in the absorber shell; the cross section of the middle shell layer is annular; two ends of the middle shell layer are communicated with a heat exchange medium pipeline; the outer flow channel is arranged in the absorber shell and is located between the middle shell layer and the absorber shell; the central flow channel is arranged in the middle shell layer; the powder collection groove is formed in one end, facing the fluid inlet end, of the central flow channel; the absorption pipe is arranged in the middle shell layerand the absorption pipe is communicated with the central flow channel and the outer flow channel to form a fluid channel. The absorber can realize the regeneration of absorbents and a regeneration manner combines indirect heating and vacuum desorption.

Description

technical field [0001] The invention belongs to the field of adsorbers, and in particular relates to a radial tubular adsorber capable of realizing combined regeneration of the adsorbent after indirect heating and vacuum desorption of the adsorbent and an adsorption and desorption method thereof. 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 adsorbent bed, 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 is saturated, which can be recovered during the regeneration process of the adsorbent 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 can be enriched and concentrated by recycling the desorbed gas in the regeneration proce...
