Continuous oxygen generator with integrated molecular sieve adsorption tower

Abstract

The invention discloses a continuous oxygen generator with an integrated molecular sieve adsorption tower. The continuous oxygen generator comprises an air compressor, a preprocessing device, an air buffering tank, an integrated molecular sieve adsorption tower, a stepping motor, a booster and an oxygen storage tank. The continuous oxygen generator is characterized in that the integrated molecular sieve adsorption tower is composed of six separated fan-shaped molecular sieve adsorption columns and can rotate under the control of the stepping motor; and an air inlet pipeline and an air outlet pipeline are separated by a two-level throttling orifice plate to form six areas, so that pressure is changed gradually. According to the continuous oxygen generator, the integrated molecular sieve adsorption tower is controlled by the stepping motor to rotate, so that a solenoid valve and a solenoid valve switching control system are omitted, the energy consumption is reduced and the oxygen generation stability is improved; pressure of each molecular sieve adsorption columns changes gradually, so that overlarge pressure change and temperature change of the molecular sieve adsorption columns are avoided and the service life of a molecular sieve is prolonged; the continuous oxygen generator is capable of generating oxygen continuously, omitting a back blowing process and improving the oxygen recovery rate; and the continuous oxygen generator is suitable for simple oxygen generation with a low purity requirement at home.

Description

Technical field [0001] The invention relates to a continuous oxygen generator, in particular to an integrated molecular sieve adsorption tower and a continuous oxygen generator. Background technique [0002] The pressure swing adsorption oxygen generator is a device that uses molecular sieve to separate nitrogen and oxygen at different pressures for nitrogen and oxygen adsorption rate and adsorption capacity. The air enters the molecular sieve adsorption tower after being pressurized by an air compressor. The molecular sieve adsorbs nitrogen at a higher pressure, and the oxygen enters the oxygen collection device through the molecular sieve adsorption tower. After the molecular sieve is saturated, the pressure is reduced and the nitrogen is desorbed. So adsorption and desorption alternately. [0003] The adsorption towers of the existing pressure swing adsorption devices mostly work intermittently with two towers, three towers, and four towers. The existing pressure swing adsorp...

Problems solved by technology

For example, the six-tower adsorption oxygen production method (publication number 101049911A) improves the oxygen recovery rate by increasing the number of adsorption towers, but ignores the impact of continuous backflushing on the oxygen recovery rate
