<p>PURPOSE: To provide a self-reproducing method in which the withdrawal and the transportation from an absorption tower is not required to minimize burning loss and the reproducing action is simple. CONSTITUTION: A method in which contaminated gas 1 is adsorbed and purified and the adsorption tower 3 whose purifying function has been lowered is reproduced consists of the following processes (a)-(c). That is, (a) a process in which gas 10 heated by a heat exchanger 9 is led to the adsorption tower 3 and is desorbed, (b) a process in which desorbed gas 11 from the process (a) is led to a burner 2 and is burned, and (c) a process in which combustion gas 18 from the process (b) is used as a heat source for the heat exchanger 9 before dissipating it in the air 20 are performed in order. Gas for heating in the heat exchanger of the process (a) is air, nitrogen or air rid of oxygen. The combustion gas used as the heat source of the heat exchanger of the process (c) is preferably dissipated in the air after passing it through a detoxicating treatment device.</p> |
