ABSTRACT:
A multi-stage, moving bed-type, adsorption device which comprises a unit made of an adsorbent particles-filled chamber which is defined by two fore and rear louvers, the distance therebetween being larger downwardly, two fore and rear lower walls extending downwardly from the lower ends of the fore and rear louvers, respectively, the distance therebetween being narrower downwardly, and two right and left side walls, an inverted V-shaped rectifying body extending horizontally from the right side wall to the left side wall and a rectifying plate extending vertically downwardly from the top of said rectifying body, said rectifying body and said rectifying plate being located in the lower region of the said chamber, a plurality of said units being placed one upon another and communicated with each other by a coupling means consisting of two vertical fore and rear walls and side walls, the distance between the louvers of the lower unit being larger than that of the upper unit adjacent thereto; a gas-circulating vessel containing said plurality of said 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.
