Working principle and process flow of pressure swing adsorption oxygen generator
PSA oxygen generator is developed based on the principle that the adsorbent has different adsorption capacity for different gas components when it is under different pressure conditions at room temperature, and completes air separation through pressure swing adsorbent. When air passes through the adsorption bed under a certain pressure condition at room temperature, the adsorbent (nitrogen, etc.) is adsorbed on the adsorption bed, and oxygen is separated. When the adsorbent on the adsorption bed approaches a certain saturation state, the air is cut off and the adsorption bed is depressurized, and the adsorbent desorbs by itself. When the pressure inside the adsorption bed drops to a certain condition, the adsorbent is desorbed and the adsorption bed resumes its adsorption capacity. This process is called fresh absorption. In this way, multiple beds are operated in a cycle to continuously separate oxygen.
industrial oxygen gas plant advantages
1.Practice has proved that PSA oxygen generator is a new generation of oxygen production device with low investment, quick effect, simple equipment, safety and reliability, and low cost. It is suitable for my country's national conditions and is conducive to promotion and application.
2. Although the PSA oxygen generator cannot meet the requirements of some high-purity oxygen, it is the most ideal oxygen generator for many oxygen-enriched operation processes, especially for oxygen-enriched operation in blast furnaces, electric furnaces, and alloy smelting, which will surely bring good economic and social benefits to enterprises.
3.With additional devices, it can be developed for a variety of uses.
(1) Adding an air mixing device and a pure control system to meet any purity >90% can meet the oxygen enrichment requirements;
(2) Adding a nitrogen purification device can increase the exhaust purity of 89% nitrogen to 99.999% high-purity nitrogen;
(3) PSA oxygen generator and small and medium-sized deep freezers can double the production of high-purity oxygen; with the application of the oxygen-enriched flame cutting device developed by NEWTEK, the cutting speed can be doubled, which can more effectively solve the problem of continuous casting flame cutting.
