<p>PROBLEM TO BE SOLVED: To effectively utilize the adsorptivity of an adsorptive material and to increase the decomposition efficiency of a catalyst when the gas discharged from an adsorption tank is subjected to, for example, decomposition treatment by the catalyst. SOLUTION: Three or more adsorption tanks 12, 13 and 14 are provided, and a feed means 15 for the gas to be treated and a feed means 16 for the gas for desorption are provided, and also a switching means is provided in the tank 12, 13 and 14, for switching to an adsorption state at which the gas to be treated is supplied to the adsorption tanks 12, 13 and 14 and a desorption state at which the gas for desorption is supplied, and the device is constituted so that plural adsorption tanks are connected in series and become the adsorption state and also at least one adsorption tank become the desorption state every switching by the switching means, and at least one adsorption tank in the desorption state is constituted so that it is in the adsorption state before being switched to the desorption state side by the switching means and also the adsorption tank is placed at the upper part side among plural adsorption tanks in the adsorption state before the switching.</p> |
