<p>An electromotive physical oxygen generator, which is composed of a means for purifying air and muffling, an air compressing pump, an autovalve for separating oxygen from nitrogen, two macromolecular sieve columns, a fine filtration tank for storing oxygen, a flowmeter and connecting conduits. Air compressed by the air compressing pump flows into an autovalve for separating oxygen from nitrogen through the conduit. Feed gas is alternatively sent into two macromolecular sieve columns via the said autovalve. Oxygen gas pass through the macromolecular sieve column into the fine filtration tank for storing oxygen, nitrogen gas is left in the column bottom and is discharged through nitrogen vents of the said autovalve. Two columns work alternatively, thereby oxygen gas is generated continuously. The electromotive physical oxygen generator may be used with an air conditioner or a humidifier.</p> |
