Description

technical field [0001] The invention relates to the technical field of oxygen production, in particular to a molecular sieve oxygen generator and a high altitude breathing ecological improvement system. Background technique [0002] Molecular sieve oxygen generator is an oxygen generator that uses pressure swing adsorption technology to extract oxygen from air. The oxygen generator is filled with molecular sieve as the adsorption medium. When pressurized, the molecular sieve adsorbs nitrogen in the air, and the remaining unadsorbed oxygen is collected to realize the separation of oxygen and nitrogen. When the molecular sieve is decompressed, the molecular sieve will The adsorbed nitrogen is released (called desorption), allowing the molecular sieve to re-adsorb the nitrogen the next time it is pressurized. Generally, it includes at least two molecular sieve adsorption tower A and adsorption tower B. The oxygen production process is: compressed air enters adsorption tower A ...

AI Technical Summary

Problems solved by technology

In order to cope with the negative impact of the low pressure and low oxygen concentration environment represented by the plateau on the oxygen production capacity and oxygen supplement effect of the oxygen generator, the general plateau molecular sieve oxygen generator is equipped with a large air compressor, resulting in a large overall volume of the oxygen generator. , heavy quality, not portable

However, in the plateau scene of the traditional portable molecular sieve oxygen generator, due to the characteristics of the plateau atmosphere, the amount of raw material gas (air) required for oxygen production is seriously insufficient, and the mass flow rate of the fan and the exhaust volume of the compressor are significantly reduced, resulting in the oxygen concentration of the oxygen-enriched gas and Significantly reduced flow, so oxygen requirements cannot be met
