Compressed air through the air purification device to remove the solid impurities such as oil, dust and gaseous water most, into the membrane separation system,separation membrane is a kind of polyester hollow fiber micro beam integratedcomponent. Under pressure, all kinds of gas adsorption, in hollow fiber membranediffusion, penetration rate of different, in sequence, we call the gas permeation ratefor "quick gas", such as oxygen, water vapor permeation rate; small "slow" of the gas,such as nitrogen. Mixed gas through the membrane, "quick gas" is enriched in thelow-pressure outside, "slow" gas is enriched in the high pressure inside, so as torealize the separation of oxygen and nitrogen. Under the control of the PLC can realize the continuous stable output product oxygen.
1, the process is simple, compact structure, very economically and meet the needs of different users of nitrogen;
2, the membrane component of resistance to high pressure, low pressure loss, can satisfy the nitrogen pressure and high users;
3, the valve switch and other moving parts, static operation, low failure rate,maintenance workload is small maintenance;
4, the device has the advantages of small occupation area, and can be used for indoor and mobile operation;
5, the standard membrane module integrated design, by increasing the membrane separation component easily finished nitrogen production capacity expansion;
6, high degree of automation, parking convenient; reach the product gasconcentration within 10 minutes;
7, the process of equipment operation and no noise, no pollution, clean product gas,low dew point.
In 8, the combustion supporting applications, it occupies a great advantage in the air separation process, lower operating energy.
And the oxygen output: 1 ~ 30000Nm3 / h, oxygen concentration 30%, membranemethod investment, maintenance and use cost is only the cryogenic and (V) by PSA70% to about 80%, and the scale is larger, more economic membrane method.
And oxygen purity: 30% ~ 45% (two grade separation oxygen purity: 90%).
