Abstract

The invention belongs to the technical field of gas purification equipment and mainly relates to circulation oxygen generation equipment which comprises an air compressor, a filter, a degreaser, a dryer, a molecular sieve adsorption tower, a membrane separator and an oxygen storage tank which are sequentially connected, wherein the molecular sieve adsorption tower comprises a tower body; an air inlet tube is mounted at the bottom end of the tower body; an air exhaust tube is mounted at the top end of the tower body; a guide rack is mounted inside the tower body; a first molecular sieve filterand a second molecular sieve filter are mounted on the guide rack; plugs are mounted at a first pressure release tube and a second pressure release tube on the guide rack; a stepper motor is in transmission connection with the guide rack and the top of the tower body; a backwash cavity is formed in the guide rack; one end of the backwash cavity is communicated with the air exhaust tube; the otherend of the backwash cavity is communicated with the first molecular sieve filter and the second molecular sieve filter respectively. The circulation oxygen generation equipment is simple in structure,the two molecular sieve filters are capable of regenerating air alternatively, oxygen can be generated continuously, and meanwhile a small floor space is needed.

Description

technical field [0001] The invention belongs to the technical field of gas purification equipment, and in particular relates to a circulating oxygen production equipment. Background technique [0002] The existing oxygen production process is generally adsorption oxygen production, mainly including PSA oxygen production and VPSA oxygen production. Take the PSA oxygen production device as an example: after the raw air is compressed by the air compressor, it is dried by the cold dryer and then enters the left adsorption tower. At this time, the pressure of the tower rises, the nitrogen molecules in the compressed air are absorbed by the zeolite molecular sieve, and the unadsorbed oxygen enters the oxygen buffer tank; Equilibrium is reached; after the pressure equalization, the compressed air enters the right adsorption tower, and the above adsorption process is repeated. At the same time, the nitrogen adsorbed by the molecular sieve in the left adsorption tower is decompressed...
