Description

technical field [0001] The invention relates to the technical field of medical gas manufacturing equipment, in particular to a single Roots pump double-action medical molecular sieve oxygen production system and an oxygen production method. Background technique [0002] At present, medical molecular sieve oxygen production equipment adopts the principle of molecular sieve pressure swing adsorption oxygen production, using air as raw material, molecular sieve as adsorbent, and using the principle of pressure swing adsorption to produce oxygen. The process of this kind of oxygen production system is: the air compressor outputs compressed air with a certain pressure, and after being filtered and purified, it enters the adsorption device composed of the adsorption tower. The nitrogen in the air is adsorbed in an adsorption tower, while the unadsorbed Oxygen flows out to generate oxygen; while one adsorption tower is adsorbed, the nitrogen adsorbed in the other adsorption tower i...
