<p>PURPOSE:To provide a gas treatment device which can prevent a lowering of effect of adsorbent. CONSTITUTION:A gas treatment device is provided, wherein specified substances in gas to be treated compressed by a compressor are adsorbed on an adsorbent 7 and the gas is delivered, while the adsorbed substances are desorbed from the adsorbent 7 utilizing the compression and pressure reduction actions generated by the compressor to discharge the substances to the outside. A cooler 8 having a refrigerant circulation passage 8a is disposed around the adsorbent 7 so as to be in thermal contact with the adsorbent, and hence if refrigerant such as water is circulated through the cooler 8, temperatures of the adsorbent 7 are kept below a predetermined temperature, thereby preventing a lowering of its effect even if compressed air of high temperature is fed into the adsorbent in an adsorption process.</p> |
