Abstract

PURPOSE: To surely cool a vacuum pump to prevent a decrease in capacity by providing an air fan on the secondary side of a separation membrane module and blowing nitrogen-enriched air against the vacuum pump from the fan, and to improve the durability of the device by cooling a controller with cooling air.
CONSTITUTION: A separation membrane module 9 having an oxygen enriching separation membrane 9a is set in a casing 1, an air fan 12 is provided on the secondary side of the module 9 with respect to the air suction port 4 of the casing 1, and a vacuum pump 14 is furnished on the delivery side of the fan 12. The fan 12 is then driven to supply air to the module 9 through the suction port 4, the obtained oxygen-enriched air is sucked by the vacuum pump 14, passed through a heat exchanger 6 and cooled, hence the moisture is condensed and separated, and the oxygen-enriched air is discharged from a discharge port 28. The heated vacuum pump 14 is cooled by the nitrogen-enriched air from the fan 12, and a part of the cooling air for the heat exchanger 6 is bypassed into the casing 1 from a bypass hole 7a to cool a controller 41.
