Abstract

The medical health care oxygen machine with molecular sieve PAS has the features of high oxygen recovering rate, low oxygen producing cost, and safe and reliable oxygen concentration for direct use in medical health care. It includes air compressor, high temperature oil separator, automatic water-draining filter, electromagnetic change valve, self-drying molecular sieve adsorber, buffer, pressure stabilizing throttle valve and non-return valve connected together. The present invention has exhausted air with oxygen concentration of 35-45 %, and is especially suitable for medical use.

Description

Technical field: [0001] The invention relates to the technical field of medical and health care equipment, in particular to a molecular sieve PSA oxygen machine for medical care. Background technique: [0002] Due to people's concern about the quality of the environment and the improvement of health care awareness, more and more attention has been paid to the use of oxygen machines. At present, in the oxygen production process, zeolite molecular sieves are generally used as adsorbents. After compressed air enters the adsorber, zeolite molecular sieves absorb nitrogen and discharge oxygen. The oxygen concentration can reach more than 90%, and the concentration of nitrogen-rich gas discharged during analysis is 93%. The remaining 7% is oxygen; the ratio of feed gas to gas production is between 6 / 1 and 7 / 1, and the oxygen recovery rate is relatively low. Due to the special requirements of the oxygen production process on the compressed air source, the air compressor must provi...
