ABSTRACT:
A multi-stage moving bed type adsorption device which comprises a unit made of a chamber filled with adsorbent particles which chamber is defined by fore and rear louvers, the distance therebetween being larger downwardly, fore and rear lower walls extending downwardly from the lower end of the respective louvers, the distance therebetween being narrower downwardly, and two right and left side walls, an inverted V-shaped cross-sectional rectifying body extending horizontally from the right side wall to the left side wall and a rectifying plate extending downwardly from the top of said rectifying body vertically, the latter two means being located in the lower region of the said chamber, a plurality of said units being placed one upon another and communicated mutually by virtue of a coupling means consisting of vertical fore and rear walls and side walls; a gas-circulating vessel including a plurality of thus communicated units therein; an adsorbent particle inlet port provided at the top of the uppermost unit; and an adsorbent particle discharging means provided at the bottom of the lowest unit, wherein the adsorbent particles flowing down within each unit are brought into contact with the gas passing through the gas-circulating vessel in a cross current manner.
