Our company's PSA oxygen generator can generally reach 90-95%, the highest can reach 98-99%
The main need to choose gas and purity of stable oxygen generator, avoid because of instability, affect ozone concentration and output. Pressure Swing Adsorption Oxygen Making Equipment (also known as PSA oxygen making equipment), under normal temperature and pressure conditions, the use of PSA special molecular sieve selective adsorption of nitrogen, carbon dioxide and water in the air and other impurities, so as to obtain high purity oxygen (93%±2). Pressure swing adsorption oxygen production equipment since entering the industrialization, the rapid development of technology, because of its price performance ratio in low and medium yield range and purity requirements are not too high of the situation has a strong competitiveness, so it is widely used in steel melting, blast furnace oxygen enrichment, pulp bleaching, glass furnaces, wastewater treatment and other fields. The research on this technology started earlier in China, but developed relatively slowly in a long period of time. Since the 1990s, the superiority of pressure swing adsorption oxygen production equipment has been gradually recognized by the Chinese people. In recent years, various processes of equipment have been put into production
The oxygen production system is mainly composed of air compressor, air cooler, air buffer tank, switching valve, absorber and oxygen balance tank. After dust particles are removed by the suction inlet filter, the raw air is pressurized by the air compressor to 3~4barg and enters one of the adsorbents. The adsorber is filled with adsorbents, in which water, carbon dioxide, and a small amount of other gas components are adsorbed by the activated alumina at the bottom of the adsorber entrance, and then nitrogen is adsorbed by the zeolite molecular sieve filled at the top of the activated alumina. The oxygen (including argon) as a non-adsorbed component is discharged from the top outlet of the adsorber as product gas to the oxygen balance tank. When the adsorber is adsorbed to a certain extent, the adsorbent will reach a saturated state. At this time, the adsorbent water, carbon dioxide, nitrogen and a small amount of other gas components will be discharged into the atmosphere through the switching valve, and the adsorbent will be regenerated.
Oxygen generator parameters: gas production: 80Nm3/h purity: 90% or more, pressure: 0.4Mpa, dimension: 2300*1500*3100 weight: 5000Kg power supply: 220V,50HZ
