<p>PURPOSE:To simplify the constitution of a valve and a control system by providing fixed valves respectively to the gas inlet part and the outlet part of a rotary adsorption tank wherein plural divided chambers are formed by partitions in the radial direction and successively passing a gaseous raw material to respective divided chambers. CONSTITUTION:A gaseous raw material is pressurized by a compressor 41 and introduced into a gas distributing part 27 through the gas introducing part 26 of a valve 22 and introduced into corresponding divided chambers 25 through the inlet part 28 of an adsorption tank and herein the impurities included in the gas are removed and purified gas is recovered through a gas outlet 29 via the outlet part 31 of a valve 23 of the adsorption tank and a gas collecting part 30. Therein by the rotation of the adsorption tank 21, when a divided chamber 25 reaches position 5, the gas incorporated therein is fed to the other divided chamber and furthermore when it reaches position 7, the gas is purged by purified gas and then when it reaches position 8, the gas is fed from the other divided chamber and pressurized.</p> |
