Working PrincipleFollowing the principle of pressure swing adsorption, high-quality carbon molecular sieve is used as the adsorbent. Under certain pressure, due to the dynamic effect, the diffusion rate of oxygen and nitrogen on the carbon molecular sieve is different. The oxygen molecules are adsorbed by the carbon molecular sieve in large quantities. Nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation. Since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, reducing the pressure can adsorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. Two adsorption tower processes are adopted, one is for adsorption and nitrogen production, and the other is for desorption and regeneration, alternating cycles and continuous production of high-quality nitrogen.
No | MAIN PART | FUNCTION | ||
1 | Air compressor | Air is used as raw material to collect & compress air to 8 bar, (Screw type) | ||
2 | Refrigerated dryer | The standard configuration removes moisture and impurities in the air, so that the air dew point reaches -20°C (the intermediate configuration uses an adsorption dryer, and the dew point reaches -40°C; the advanced configuration uses a combined dryer, and the dew point reaches- 60ºC). | ||
3 | Precision Filter | A/T/C three-stage filter to remove oil, dust and impurities. | ||
4 | Air buffer tank | Store pure and dry air for subsequent adsorption and separation of oxygen and nitrogen as raw material storage. | ||
5 | Adsorption tower | A&B adsorption tower can work alternately, regenerating adsorption, filling sodium molecular sieve to filter out oxygen molecules. | ||
6 | Analyzer | Real-time monitoring and analysis of oxygen & nitrogen purity, indicating that the equipment is working normally and alarming. | ||
7 | Valves & pipelines | Intelligent control valves realize automatic operation of equipment, PLC control, SUS304 pipelines. | ||
8 | Gas Buffer Tank | Store oxygen & nitrogen with qualified purity, which can be directly piped or used for bottle filling. | ||
9 | Pressure regulator | Adjust and temperature the outlet pressure of oxygen & nitrogen (3-6 Bar). | ||
10 | Dust filter | Remove the dust brought by molecular sieve in oxygen & nitrogen | ||
11 | Check valve | Prevent oxygen & nitrogen back flow | ||
12 | Gas Booster | Pressurize the oxygen&nitrogen to the filling pressure, generally 150bar or 200bar. | ||
13 | Filling Manifold | Split high-pressure oxygen & nitrogen into each gas cylinder |
Rubber industry: packaging and storage of rubber; Tire production, etc.
