Oxygen enrichment device

Disclosed is an oxygen enrichment that can follow changes in adsorption performance in response to changes in the temperature of the usage environment and can reduce power consumption. The oxygen enrichment device has a purge step control means that controls a purge step time to increase/decrease the length of a purge step so as to maximize the oxygen concentration by changing opening/closing timing of a flow-channel switching means while the oxygen enrichment device is running.

Oxygen concentrator

A pressure change adsorption type oxygen enricher including an adsorption bed packed with an adsorbent capable of selectively adsorbing nitrogen rather than oxygen; a compressor for feeding air to the adsorption bed; a flow channel switching valve for repeating with a given timing the adsorption operation of feeding the air from the compressor to the adsorption bed and taking out enriched oxygen and the desorption operation of depressurizing the adsorption bed to regenerate the adsorbent; and flow rate measuring means for measuring the flow rate of supply of produced enriched oxygen. The oxygen enricher is characterized by having pulsation detecting means for detection of any pulsation of supply oxygen and further having control means for control of the rate of air fed from the compressor on the basis of detection results. Thus, an apparatus satisfying the requirement of secondary features, such as compactness, low power consumption and noiselessness, is realized by paying attention to the fluctuation of product flow rate caused by suppression of the rate of oxygen produced and carrying out the feedback control of production rate by a flow rate sensor alone.
