<p><P>PROBLEM TO BE SOLVED: To provide a solvent cooling and separating apparatus of a gas treatment apparatus, which uses a Peltier element to cool, concentrate and separate a solvent concentrated gas containing a solvent desorbed from activated carbon and does not need cooling water. <P>SOLUTION: In the solvent cooling and separating apparatus, the flow path of the solvent concentrated gas flowing out from an activated carbon tank 10 and the flow path of inert gas flowing into the activated carbon tank 10 are adjacently disposed, and the Peltier element 46 is disposed at a partition wall 42 partitioning the two flow paths so as to expose one heating or cooling surface to the flow path of the solvent concentrated gas and expose the other heating or cooling surface to the flow path of the inert gas. In a desorption process, the solvent concentrated gas is cooled and the solvent is concentrated and separated by the cooling of the Peltier element 46, and the inert gas is heated by the heating of the Peltier element 46 simultaneously. The cooling water is not needed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
