Air compressor to provide compressed air first into the compressed air purification components, compressed air first by the pipeline filter to remove most of the oil, water, dust, and then by the freeze dryer to further water, fine filter degreasing, dust, And is purified by a super-fine filter immediately following it. According to the system conditions, Chen Rui air separation gas specially designed a set of compressed air degreaser, used to prevent the possible emergence of trace oil penetration, carbon molecular sieve to provide adequate protection. The rigorous air purification components ensure the service life of carbon molecular sieves. Clean air treated with this unit can be used for instrument air.
The effect of the air tank is to reduce the pulsation of the air flow and to mitigate the pressure fluctuation of the system so that the compressed air is smoothly passed through the compressed air purifying component so as to sufficiently remove the oil-water impurities and reduce the load of the subsequent PSA oxygen-nitrogen separation unit. At the same time, it also provides a large amount of compressed air required for rapid boosting of the PSA oxygen-nitrogen separation unit during the operation of the adsorption tower, so that the pressure in the adsorption tower rises quickly to the working pressure to ensure the equipment is reliable and stable run.
A dedicated carbon molecular sieve adsorption tower with A, B two. O2, CO2 and H2O are adsorbed when the clean compressed air enters the inlet of the A tower through the carbon molecular sieve to the outlet end, and the product nitrogen flows out of the outlet of the adsorption tower. When the temperature of the nitrogen concentration of the outlet side of the set value, the PLC program, automatic vent valve open, the non-qualified nitrogen automatically vent to ensure that substandard Nitrogen Gas Generator does not flow to the gas point. When the gas is vented, the noise is less than 75dBA by using the silencer.
