RESUMO
OBJECTIVE@#In order to solve the problem that the existing oxygen production technology cannot simultaneously produce pure oxygen, high-purity oxygen, ultra-pure oxygen, and the modular expansion of oxygen production capacity, a new type of electrochemical ceramic membrane oxygen production system was discussed and developed.@*METHODS@#Through the design of the ceramic membrane stack, airflow distributor, heater, double spiral exchanger, thermal insulation sleeve, control panel, control box and auxiliary system in the electrochemical ceramic membrane oxygen generator, a modular oxygen production system is formed.@*RESULTS@#The modular design can produce pure oxygen, high-purity oxygen and ultra-pure oxygen to meet various oxygen consumption needs.@*CONCLUSIONS@#The electrochemical ceramic membrane oxygen production system is a new type of oxygen production technology. The main components have no moving parts, no noise, and no pollution. It can produce pure oxygen, high-purity oxygen and ultra-pure oxygen on site, with small size, light weight, and module combination which is suitable for convenient expansion and installation of oxygen consumption.
