1. Working principle
PSA nitrogen making machine is based on the principle of pressure swing adsorption, the use of carbon molecular sieve adsorption quality is very high, in the mechanical role, the carbon molecular sieve oxygen is far greater than the diffusion rate of nitrogen in the micropores, the adsorption is unbalanced, nitrogen enrichment in the gas phase, the formation of product nitrogen. Then decompress to atmospheric pressure, adsorption-desorption regeneration of adsorbed oxygen and other impurities is achieved. In the conventional setup of the two adsorption tower system, the nitrogen adsorption capacity of one tower and the desorption regeneration of the other tower are automatically controlled by the PLC program, so that the two towers are circulated to achieve the purpose of continuous production of high-quality nitrogen. Under pressure, pressure swing adsorbs clean, dry compressed air, and desorbs in adsorption vacuum.
The company can provide nitrogen making machine from 5-3000nm3 / H output, cold storage from 95% to 99.9995% purity, can be widely used in chemical, electronic, textile, coal, oil, natural gas, pharmaceutical, food, glass, powder metallurgy, machinery, magnetic materials and other industries not. Welcome new and old customers to visit our company to negotiate cloak.
2. Technical indicators
Air compressor pressure: 0.6-1.0mpa Nitrogen flow rate: 3-3000nm3 / h Nitrogen purity: 90%-99.9995%
Nitrogen outlet pressure: 0.2-0.85mpa Material: clean compressed air
3. Process flow
The nitrogen machine in the cold storage consists of compressed air compressor, air drying purification system, PSA nitrogen production and nitrogen pressurization system components.
Raw air compressor pressure 0.8MPa, compressed air purification system to remove oil, water, dust and other impurities, into the adsorber. After purification, the pure raw material air is dried, the buffer filter enters the bottom of the adsorber, the air flows through the distributor, fills the carbon molecular sieve adsorber, PSA, and realizes the separation of oxygen and nitrogen. Nitrogen is abundant in the gas phase, as a product from the upper outlet into the nitrogen buffer tank, pressure regulator, output end of the flow meter, exhaust muffler.
4, open the technical characteristics of the total nitrogen machine
PLC automatic control (if required, remote control can be achieved), no foundation installation (overall system in steel frame), no personal care, low energy consumption (kW/h - 250kW/h), small footprint (3 square meters to 8 square meters).
