Problems solved by technology
When the molecular sieve adsorbed nitrogen in the adsorption tower reaches a saturation level, switch to another adsorption tower to continue the adsorption. Part of the oxygen is introduced into the first adsorption tower for purging to accelerate the discharge of nitrogen, so that it circulates, but its volume is large and it takes up a lot of space

Description
technical field [0001] The invention belongs to the technical field of oxygen production, and in particular relates to a PSA oxygen production device. Background technique [0002] The common oxygen generator is double adsorption tower oxygen generator, which uses air as raw material, molecular sieve as adsorbent, and adopts the principle of pressure swing adsorption to produce oxygen. The raw air is first pressurized by an air compressor, and the compressed air is cooled, dewatered, filtered and enters an adsorption tower equipped with molecular sieves through the directional control valve. The nitrogen in the air is absorbed by the molecular sieves, and the oxygen enters the oxygen tank through the adsorption tower. When the molecular sieve adsorbed nitrogen in the adsorption tower reaches a saturation level, switch to another adsorption tower to continue the adsorption. Part of the oxygen is introduced into the first adsorption tower for purging to accelerate the dischar...
