Abstract

The invention discloses a temperature swing adsorption gas purification device, and aims to solve the problems that regeneration gas required by the conventional temperature swing adsorption separation device is needed to be input from outside and high in consumption, and the device is high in operating cost. The device comprises a feed port, at least three adsorbers, coolers, heaters and a discharge port, wherein the feed port, the adsorbers and the discharge port are connected through pipelines; the coolers, the heaters and the adsorbers are connected through pipelines; adsorption towers are connected through pipelines; and valves are arranged on the pipelines. A small amount of regeneration gas is required, energy consumption is low, the device is flexibly operated, energy can be effectively saved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of temperature swing adsorption, in particular to a temperature swing adsorption gas purification device. Background technique [0002] At present, in industrial production, the temperature swing adsorption process is mainly used to separate and purify gases. Temperature swing adsorption uses the characteristic that the equilibrium adsorption capacity of the adsorbent decreases with the increase of temperature, and separates the gas through normal temperature adsorption and temperature rise desorption. It usually includes three steps: adsorption, heating regeneration and cold blowing. The purpose of continuously purifying the gas is achieved by circulating operation among the three steps. Among them, the heating regeneration and cooling of the adsorbent have an important impact on the continuous and stable operation of the adsorption process and the operating cost of the entire device. [0003] Since the adsorber is...
