<p>PURPOSE:To miniaturize a system by using a compressor for supply of raw material gas which is used in an adsorption process, combinedly as a vacuum pump for the desorption process in the application of a pressure swing adsorption method. CONSTITUTION:Raw material air is pressurized by a compressor 1 through a three-way valve 5, and condensate is separated by a drain separator 2. Next, the raw material air is fed into an adsorptive floor storage container 3 and N2 is extracted as a finished product gas via a valve 8 with O2 adsorbed. After this, the N2 gas is stored in a pressure adjustment tank 4. In the meantime, in the desorption process, the adsorptive floor storage container 3 is subjected to pressure reduction to atmospheric pressure by means of a valve 7 and a surplus air is released outside the system. Then the adsorptive floor storage container 3 and the compressor 1 are connected for decompression, and the air thus replaced is discharged into an atmosphere through the three-way valve 6.</p> |
