IPC: D06F43/08
Filed: 1988-08-22
Abstract: PURPOSE:To improve an absorption factor by means of activated coal in the same amount as that of a single drum type and to compact a device by a method wherein an activated coal tank is of a double barrel type in which a single tank is divided, and in a deodorizing process, fed solvent gas is simultaneously adsorbed by means of two activated coal tanks. CONSTITUTION:Activated coal is divided into two tanks, and when activated coal in the one tank 2a is in an adsorbing state, activated coal in the other tank 2b is detached and dried. In a deodorizing process of a dry cleaner, control is made so that outlet inlet dampers 7a, 7b, 8a, and 8b connected to the two activated coal tanks 2a and 2b are all opened. Thus, solvent-containing gas passes both two lots of activated coal 1a and 1b, and a solvent is adsorbed approximately in equal amounts in both two lots of activated coal. This constitution, since, in an activated coal amount, a device can be formed by 1/2 an amount required for a conventional double barrel-type device, enables reduction of an initial cost and compacting of a device.
