Description

technical field [0001] The invention belongs to the technical field of oxygen generators, and in particular relates to an oxygen generator for a medical-grade high-temperature molecular sieve membrane adsorption tower and a method for using the same. Background technique [0002] With economic development and improvement of medical security conditions, the demand for medical oxygen is increasing year by year. The medical molecular sieve oxygen generation system adopts the molecular sieve pressure swing adsorption technology at room temperature and low pressure. Its process flow is simple, the investment is small and the maintenance is convenient. Therefore, most small and medium hospitals use the molecular sieve oxygen generation system as the oxygen source. At present, there are many models of medical molecular sieve oxygen generation systems available on the market, but their process flow and main structure are the same. The core is composed of air compressor, oxygen gener...
