Gansu plastics are plastics with nitrogen Nitrogen equipment repair factory price 1, compressed air purification components Gansu PSA air compressor provides first pass into the air purification components, the air filter to remove most of the first by pipeline oil, water, dust, and then freeze-drying machine further remove water fine filter 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 device is equipped with a total PSA Gansu A special carbon molecular sieve adsorption towers 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. The company provides production from 3-3000Nm3 / h, the purity from 95% - 99.9995% of the nitrogen equipment can be widely used in chemical, electronics, textile, coal, oil, gas, glass, machinery, powder metallurgy, magnetic materials and other industries. Using a wide range: nitrogen protective gas metal heat treatment process, the chemical industry and the production of various types of gas storage tanks, pipelines purification, rubber, plastic products, gas, exhaust oxygen atmosphere packaging, clean and cover gas, nitrogen packaging and containers of nitrogen oxide discharge, the electronics industry and the protection of gas and other electronic components semiconductor manufacturing process. Purity, flow, pressure is adjusted, to meet different customer needs. Gansu PSA welcome new and old customers to visit our company to negotiate.
