<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for adsorption and concentration, which is used for an exhaust gas treatment apparatus containing an organic solvent, which can remove gases without changing treatment air flow and faults even when gas concentrations fluctuate, and which can supply stable concentrated gases. <P>SOLUTION: An adsorption means 1 is provided with an adsorption part 1a and a desorption part 1b, which can be switched at cycles determined by an adsorption/desorption cycle-adjusting means 3. An inlet-concentration measurement means 2 is provided at the inlet of the adsorption part 1a. The signal of a measured concentration is sent to the adsorption/desorption cycle-adjusting means 3. Air for desorption is sent by a fan 5 to the desorption part 1b. Gases are desorbed from the desorption part 1b and then the concentrated gases are supplied to a secondary treatment means. With the above configuration, the amount of gases to be adsorbed to the adsorption means 1 can be stabilized even when the concentration of exhaust gases fluctuate. As a result, this makes it possible to positively remove gases and to obtain stable concentrated gases. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
