Description

technical field [0001] The present application relates to the technical field of oxygen production, in particular to an electrochemical ceramic membrane oxygen generator and its oxygen production equipment. Background technique [0002] At present, oxygen is mainly obtained through separation, and there are three technical methods for air separation: cryogenic method, adsorption method, and organic membrane separation method. [0003] Cryogenic method: Utilizing the different boiling points of the components in the air, through a series of processes, the air is liquefied, and the different components are separated by rectification. This method can realize the complete separation of air components, product refinement, large-scale equipment, and dual state (liquid and gas), so the industrialization of the production equipment occupies a leading position. At present, the most widely used in industry is cryogenic air separation technology. The concentration of oxygen produced ...

AI Technical Summary

Problems solved by technology

Due to the low oxygen and nitrogen separation coefficient of the organic membrane, poor thermal stability, short service life, and easy to block, the purity of oxygen products is generally ≤45%, and the oxygen production capacity is small, which cannot meet the oxygen consumption requirements of the metallurgical industry and the three major chemical industries. quantity and quality of oxygen

[0006] The existing oxygen production technology cannot produce pure oxygen, high-purity oxygen and ultra-pure oxygen at the same time on site, and cannot meet the oxygen demand of various industries at the same time: cryogenic gas separation can only be realized in a low temperature environment below 100K, and the investment is large , only suitable for large-scale gas separation process, for medical and other small and medium-scale dispersed applications, the oxygen produced by cryogenic method needs to be packaged, distributed and stored, the fire protection requirements are high, and it cannot be produced and used on the spot; membrane separation Oxygen concentration of the products produced by the method is low (less than 45%), and the scale is only suitable for small and medium-sized. 96%, there are many moving parts, loud noise, regular maintenance is required, as the service life increases, the concentration pressure will attenuate, the failure rate will increase, and the use cost will be high
