Ningxia Nitrogen equipment Barnes purification equipment Co., Ltd. is a research, development, nitrogen machine (PSA Nitrogen equipment), industrial oxygen (PSA oxygen equipment), gas purification, air purification and other gas equipment, but also to undertake various gases non-standard equipment design and technical advice. Nitrogen works, Nitrogen Generator is based pressure swing adsorption principle, the use of high-quality carbon molecular sieve as adsorbent, at a certain pressure, take nitrogen from the air system. Purified dry compressed air, pressurized adsorption in the adsorption, desorption decompression. Since aerodynamic effects in porous carbon molecular sieve oxygen diffusion rate than nitrogen, oxygen is preferentially adsorbed carbon molecular sieve nitrogen be enriched in the gas phase to form nitrogen products. Then by vacuum to atmospheric pressure, adsorbent desorption of oxygen and other impurities, to achieve regeneration. General settings in the system of two absorption tower, a tower production of nitrogen adsorption, desorption regeneration of another tower, hoist pneumatic valve control by PLC program controller, so that the two towers cycles in order to achieve continuous production of high quality nitrogen purposes . The entire system consists of the following components: compressed air purification components, air tanks, oxygen and nitrogen separation device, nitrogen buffer tank. 1, compressed air purification components air compressor to provide first pass into the air purification components, the compressed air pipe filter first by removing most of the oil, water, dust, and then freeze-drying machine further removal of water, fine filtration is oil, dust, followed by the ultra-fine filter deep purification. The system conditions, Barnes purge gas specially designed set of compressed air degreasing, to prevent a possible trace oil penetration, to provide adequate protection for the carbon molecular sieve. Air purification components designed to ensure strict carbon molecular sieve life. After clean air after this assembly process can be used for instrument air. 2, the role of air tanks air tank is to: reduce air flow pulsation dampening effect; thereby reducing system pressure fluctuations, compressed air smoothly through the air purification components, in order to fully remove water impurities, reduce subsequent PSA oxygen and nitrogen separation load device. Meanwhile, in the adsorption tower work switch, it also provides for the separation of oxygen and nitrogen PSA apparatus needed boost short time a lot of air, so that the adsorption tower pressure quickly rose to the working pressure to ensure a reliable and stable equipment run. 3, oxygen and nitrogen separation apparatus equipped with carbon molecular sieve adsorption towers for a total of A, B two. When the clean compressed air into the inlet end of column A to the outlet end with carbon molecular sieve flow, O2, CO2 and H2O are adsorbed, nitrogen product from the outlet end of the adsorber effluent. After some time, the carbon molecular sieve adsorption tower A saturation. In this case, A tower automatically stop adsorption, oxygen flow to the B tower production of nitrogen, and A molecular sieve regeneration tower. The molecular sieve is regenerated by the adsorption tower rapidly decreased to atmospheric pressure to remove adsorbed O2, CO2 and H2O to achieve. Two towers alternate adsorption and regeneration, complete oxygen and nitrogen separation, continuous output of nitrogen. The above-mentioned process by the programmable logic controller (PLC) to control. When the size of the outlet end of the set value purity nitrogen, PLC program effects, automatic vent valve opens, the failure nitrogen automatically vented to ensure that substandard nitrogen gas does not flow to the point. The use of the gas vent silencer muffler the noise is less than 75dBA. 4, nitrogen buffer tank buffer tank for nitrogen balance is separated from nitrogen-oxygen separation system out of the nitrogen pressure and purity, to ensure a continuous supply of stable nitrogen. At the same time, the adsorption tower after the handover work, it will be part of the gas back-filled absorption tower itself, on the one hand to help boost adsorber, the bed is also protect the role played a very important process in the device during operation a supporting role. . Barnes & Noble's PSA nitrogen technology is widely used in chemical, electronics, textile, coal, oil, gas, glass, machinery, powder metallurgy, magnetic materials and other industries. . For different requirements of different users in different sectors of nitrogen use, Bono provide personalized, professional PSA nitrogen production equipment, fully meet the gas requirements of different users. .
