psa pressure swing adsorption nitrogen production equipment

According to the principle of pressure swing adsorption, high-quality carbon molecular sieve is used as the adsorbent, and nitrogen is produced from the air under a certain pressure. The purified and dried compressed air is subjected to pressure adsorption and decompression desorption in the adsorber. Due to the aerodynamic effect, the diffusion rate of oxygen in the pores of carbon molecular sieve is much higher than that of nitrogen, oxygen is preferentially adsorbed by carbon molecular sieve, and nitrogen is enriched in the gas phase to form finished nitrogen. Then, after decompressing to normal pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower absorbs nitrogen and the other tower desorbs and regenerates. The opening and closing of the pneumatic valve is controlled by the PLC program controller, so that the two towers circulate alternately, so as to achieve the purpose of continuous production of high-quality nitrogen. .

Features
1. The raw air is taken from nature, and nitrogen can be produced only by providing compressed air and power supply. The equipment has low energy consumption and low operating costs.
2. The nitrogen purity is easy to adjust. The nitrogen purity is only affected by the nitrogen exhaust volume. The ordinary nitrogen purity can be adjusted arbitrarily between 95% and 99.99%; the high-purity Nitrogen Generator can be arbitrarily adjusted between 99% and 99.999%.
3. The equipment has a high degree of automation, fast gas production, and can be unattended. Start and shut down only need to press a button, and it can generate nitrogen within 10"5 minutes of startup.
4. The process flow of the equipment is simple, the structure of the equipment is compact, the floor area is small, and the equipment is highly adaptable.
5. The molecular sieve is loaded by the snowstorm method to avoid the pulverization of the molecular sieve caused by the impact of high-pressure airflow, and to ensure the long-term use of the molecular sieve.
6. The digital display flowmeter is a secondary instrument for industrial process monitoring with pressure compensation and high precision, and has the functions of instantaneous flow and cumulative calculation.
