Principle

      Compressed air through the pretreatment system to detach oil, dust, other solid impurities, and most of the gaseous water, enter into the absorption tower be loaded with zeolite molecular sieve(ZMS), the nitrogen, carbon dioxide, water vapor are adsorbed, oxygen through the adsorption bed to be separated.

      When adsorbed impurities within the adsorption tower up to a certain extent, desorb the atmosphere, make the adsorbent regeneration. Consists of two or three towers adsorption separation system under the control of PLC or DCS system cycle switch complete continuous production of oxygen, so-called normal pressure desorption, pressure swing adsorption generate oxygen (PSA-O2). PSA oxygen generation adsorb in a slightly higher pressure (0.35MPa~0. 8MPa), desorb in normal pressure emptying.

Features

1. Specific protection measures of molecular sieve, with less amount, long service life;

2. Low energy consumption, the product of high oxygen purity;

3. reasonable internal components, air distribution uniformity, reduce air high-speed impact;

4. The whole equipment of a high degree of automation;

5. Multifunctional monitoring system, realize gas, purity, pressure LCD online display, equipment failure warning, maintenance tips, fully grasp equipment running states;

6. Can be fully integrated skid mounted design, easy installation and rapid deb ing;

7. Optional oxygen flow, remote monitoring system, etc.

Specifications
