The Working Process Of Medical Oxygen Concentrator

The oxygen production process of a medical oxygen concentrator (pressure swing adsorption oxygen concentrator) uses air as the raw material for oxygen production. After filtration (removing oil, dust, moisture, solid impurities, etc. from the air), the air is compressed by a compressor. The compressed high-pressure air is cooled and enters an adsorption tower for adsorption and separation. The adsorption tower is equipped with molecular sieves, which adsorb nitrogen and carbon dioxide. The gas flowing out of the adsorption tower is high-purity oxygen, which can be used as medical oxygen. The separated oxygen enters the gas storage tank through a one-way valve, is depressurized by a pressure reducing valve, and then flows out through a flow meter and a humidification bottle for user use; The other part of the oxygen is used to backwash and clean the adsorber in a desorption state, and the desorbed nitrogen is discharged through a muffler
