Vacuum pressure swing adsorption air separation oxygen, is made of high quality zeolite molecular sieve adsorption of nitrogen, not assembled at the top of the tower by adsorption of oxygen and as to product gas oxygen storage tank. When in the adsorption state of adsorption tower before approaching saturation, the automatic vacuum desorption tower regeneration, and the other an adsorption tower started making oxygen pressure adsorption. Two working alternate adsorption tower, completed by psa process. Adsorption desorption tower regeneration, using negative pressure, called VPSA oxygen.
Device technology:
Pressure swing adsorption air separation oxygen generating device of the adsorption bed must contain two steps: adsorption and desorption. In order to get products continuously, usually in the oxygen generating device are two or more of the adsorption bed, and from the perspective of energy consumption and stability, also set up some necessary auxiliary steps. Each adsorption, the adsorption bed is typically put pressure, time or decompression regeneration, rinse steps, such as displacement pressure and booster periodically repeated operation. At the same time, the adsorption bed, respectively in different steps, under the control of PLC timer switch, to coordinate several adsorption bed operation, staggered on the pace of time, make the pressure swing adsorption device can run smoothly, continuous product gas. For the actual separation process, must also consider the other trace components in the air. Carbon dioxide and water on the usual adsorbent adsorption ability than nitrogen and oxygen, usually more, you may add in adsorption bed suitable adsorbent (or use oxygen adsorbent itself) to make it clear by adsorption.
Technical features:
1, civil engineering quantity is small, equipment installation period shorter than cryogenic device, and investment;
2, oxygen and lower power consumption, low energy consumption;
3, equipment operation and maintenance cost is low;
4, equipment running high degree of automation, convenient parking, less operators;
5, equipment operation stability is strong, high security;
6, the operation is simple, the main parts were picked from the international famous manufacturers;
7, using imported from oxygen molecular sieve, superior performance, long service life.
Technical indicators:
Product size: 100 ~ 10000 nm3 / h
Oxygen pressure: 0.015 ~ 0.05 MPa (adjustable)
The oxygen purity: 70 ~ 95%
