First, according to different industry different user requirements for different use of oxygen, oxygen Reed to provide personalized, specialized equipment, fully meet the requirements of different users.PSA PSA system is the use of special gas adsorbent at room temperature will be on-site equipment in the air oxygen enrichment is out of use of pressure swing adsorption technology RDO series. The PSA system provided by Reed is a new type of high-tech equipment, it has the advantages of low equipment cost, small volume, light weight, simple operation, convenient maintenance, low running cost, oxygen fast, convenience, no pollution etc. can be connected to the power supply of oxygen, can be widely used In the petrochemical industry, electric furnace, glass production, papermaking, ozone, aquaculture, aerospace, medical and other industries and fields, equipment operation is stable, safe and reliable, favored by the majority of users. We are equipped with a dedicated gas field application research team, a wide range of products, in addition to industrial gas and device the edge products and services, access to a larger market share. In two, the PSA machine based on zeolite as adsorbent, using pressure adsorption principle, step-down desorption adsorption and release of oxygen from the air, thereby separating the automation equipment of oxygen. Zeolite molecular sieve is a kind of special hole after Type of processing processing, surface and internal full spherical granular adsorbent micropore was white. The pass characteristics make it possible to achieve O2, the dynamic separation of N2. The O2 zeolite molecular sieve, separation effect of N2 is small difference dynamics of the two gases diameter based on diffusion rate the microporous N2 molecules in zeolite molecular sieve, O2 molecular diffusion rate is slower. The diffusion of compressed air in the water and CO2 with little difference. From the end of the nitrogen adsorption tower is enrichment of oxygen molecules. Three applications: electric furnace steelmaking decarburization, oxygen combustion heating, foam slag, metallurgical and order plus Heat: activated sludge wastewater treatment. The oxygen enriched aeration pool, oxygen and ozone sterilization. Oxygen combustion glass melting: solubilization, cutting, increase the glass production, prolong the service life of furnace. The bleaching of pulp and paper: chlorine bleaching into oxygen bleaching, providing cheap oxygen, sewage treatment. The non-ferrous metal smelting smelting steel, zinc nickel, lead, etc. with rich oxygen, PSA is gradually replacing the cryogenic cutting field. Field construction steel with oxygen cutting steel, mobile or small oxygen generator can meet the requirements. Petrochemical and chemical oxygen: Petroleum and chemical reaction in the process of using oxygen enriched oxygen instead of air oxidation reaction, can improve the reaction Speed and chemical products production. Ore processing for gold production process, the extraction rate can be improved. Aquaculture: oxygen enriched aeration can increase the dissolved oxygen in water, a substantial increase in the yield of fish, can transport oxygen for fish, intensive fish. Fermentation with enriched oxygen instead of air for the aerobic fermentation of oxygen, can greatly improve the efficiency of drinking water: provide oxygen to the ozone generator, oxygen sterilization. Since four, the process: the air compressor after compression, after removal, degreasing, drying, into the air storage tank, through the air inlet valve, inlet valve into the left left adsorption tower, tower pressure, compressed air nitrogen molecules in zeolite molecular sieve absorption Attached, not adsorbed oxygen through the adsorbent bed, after the left production valve, oxygen production valve into the oxygen tank, this process is called left suction, lasts for a few seconds. The left suction after the end of the process, the left and right adsorption tower adsorption tower are communicated through the pressure valve, so that the two tower pressure to balance this. The process is called pressure, duration of 3~5 seconds. Pressure after the compressed air through the air inlet valve, inlet valve into the right right adsorption tower, compressed air nitrogen molecules in zeolite molecular sieve adsorption and enrichment of oxygen after right production valve, oxygen production valve into the oxygen tank, this process is called the right suction, lasts for a few seconds and left. Zeolite molecular sieve oxygen adsorption tower through the left exhaust valve pressure released back into the atmosphere, this process is called desorption. Whereas the left tower adsorption tower also in desorption. Right for nitrogen to make the molecular sieve pressure release of the total emissions into the atmosphere, oxygen through a normally open reverse blow valve blowing sweep the desorption of the adsorption tower is the tower, the nitrogen blowing adsorption tower. This process is called reverse blowing, and desorption was performed at the same time. The right end of the suction pressure, into the process, and then switch to the left suction process, has been based on, thereby continuously produce high purity products of oxygen. Five, technical indicators: oxygen production: 5-300Nm 3/h oxygen purity: 93%--96% oxygen pressure: 0.2 - 0.3Mpa dew point: --40 (atmospheric pressure)
