<P>PROBLEM TO BE SOLVED: To solve the following problem: as air is passed through a plurality of cold heat processes comprising cooling, heating, and cooling, for recovering organic solvent gas, the energy consumption becomes large and the control becomes complicated. <P>SOLUTION: An organic solvent gas treatment apparatus is provided where a rotating adsorption rotor 2 is divided into an adsorption zone 7, a regeneration zone 6, and a purge zone 5 and a cooler unit 3 is provided upstream of the adsorption zone 7, first, the organic solvent gas is passed through the regeneration zone 6 to make the concentration high, then liquefied and recovered in the cooler unit 3, the cooled organic solvent gas-containing air is passed through the adsorption zone 7 to be cleaned, and the cleaned air is passed through the purge zone 5 to be cooled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
