Variable frequency altitude self-adaption pressure swing adsorption oxygenator and oxygen generation method

Abstract

The invention provides a variable frequency altitude self-adaption pressure swing adsorption oxygenator and an oxygen generation method. The oxygenator comprises an air compression unit, a heat dissipating dry unit, an oxygen generation adsorption unit, a pressure sensor, a control unit and a frequency converter. A first output end of the air compression unit is connected with a first input end of the heat dissipating dry unit, and a first output end of the heat dissipating dry unit is connected with a first input end of the oxygen generation adsorption unit. An input end of the pressure sensor is connected with the first output end of the heat dissipating dry unit, and an output end of the pressure sensor is connected with a first input end of the control unit. An input end of the frequency converter is connected with a first output end of the control unit, and an output end of the frequency converter is connected with a first input end of the air compression unit. The control unit changes the power working frequency of the air compression unit through the frequency converter according to a control signal transmitted by the pressure sensor. The variable frequency altitude self-adaption pressure swing adsorption oxygenator and the oxygen generation method can meet the oxygen generation requirements in all areas where the air thickness degrees are different at different altitudes.

Description

technical field [0001] The invention relates to a frequency conversion type altitude adaptive pressure swing adsorption oxygen generator and an oxygen generator method, belonging to the field of medical and health care equipment. Background technique [0002] Pressure Swing Absorption (PSA) oxygen production technology uses air as raw material and zeolite molecular sieve as adsorbent. After a certain pressure is applied to the air, it is passed into the adsorbent. Under a certain pressure, zeolite molecular sieve can adsorb Nitrogen in the air, so as to enrich the oxygen in the air, and when the zeolite molecular sieve is saturated with adsorbed nitrogen, the zeolite molecular sieve is depressurized to desorb and discharge the nitrogen gas, and the zeolite molecular sieve is regenerated and reused. Therefore, the pressure swing adsorption oxygen production technology separates the oxygen and nitrogen in the air raw material through the rapid cycle process of pressure adsorpt...
