<p>PURPOSE:To reduce the regenerating time by providing an adsorption tower having spaces above and below the adsorbent, a heat exchanger arranged in the upper space, a means for circulating the gas in the lower space through the heat exchanger, and a heating means set in the adsorbent. CONSTITUTION:The adsorbent 2 is placed in the adsorption tower 1, and the upper space 3 and the lower space 4 are formed above and below the adsorbent 2. When the adsorbent is regenerated, the adsorbent is heated by the heater 5 in the adsorbent 2, and the heated gas is accumulated in the upper space by convection. In this case, a fan 7 is driven to send the gas staying cold in the lower space 4 to the heat exchanger 6 in the upper space 3, the heated gas is returned to the lower space 4, and the temp. distribution in the adsorption tower 1 is uniformized.</p> |
