The pressure swing adsorption nitrogen generator adopts the most mature and reliable pressure swing adsorption technology in the world, combined with the unique process flow, optimized pipeline design and advanced filling technology, to strip the carbon molecular sieve CMS, and effectively prevent it. Occurrence of adsorption tower tunnel effect. Thereby, the performance of carbon molecular sieve is greatly improved. It can produce 97% to 99.999% pure nitrogen in one step while saving energy. If there are special requirements, the purity can reach 99.9995%.

High-quality nitrogen to meet the needs of various industries. Due to its precision filter, fine nitrogen dust particles are less than 0.01 μm and oil content is less than 0.01 ppm. Equipped with adsorption dryer, sterilization filter device, etc., it can meet the high requirements of liquid crystal display, crystal oscillator, food, medicine and other special industries.

Low operating cost: PSA nitrogen generators use clean compressed air as raw material, without chemical consumption, and can produce nitrogen of different purities to meet your requirements. The total cost is liquid nitrogen or gas nitrogen. With 10-35%, you can save a lot of money.

Advanced unmanned operation: The self-developed oxygen purity analyzer monitors the nitrogen purity in real time, and automatically releases nitrogen with unqualified purity to prevent the impact of impure gas on product quality. Highly reliable PLC control is possible. Achieve 24-hour automatic unmanned operation.

Composition of pressure swing adsorption molecular sieve nitrogen generator

1. The compressed air purification component is composed of a high-efficiency degreasing agent, a freeze dryer, a precision filter, and an activated carbon filter. The working principle is to enter the air buffer tank for buffering, and then enter the high-efficiency degreaser to remove most of the impurities such as oil, water, dust, etc., and then use the refrigerator dryer to further remove moisture, oil and dust. . The activated carbon filter passes through the fine filter and then enters to further remove the oil.

2. The oxygen and nitrogen separation system consists of adsorption tower, compression device, auxiliary valve, electrical appliances, etc. The adsorption tower is designed with a composite floor structure and is divided into two towers, A and B, filled with imported carbon molecular sieves (stretching and torsional vibration filling method to make the carbon molecular sieves more uniform). The clean compressed air first passes through the carbon molecular sieve from the inlet end of the A tower to the outlet end. At this time, O2, CO2, H2O are adsorbed, and the nitrogen of the product flows out from the outlet end. adsorption tower.

3. The oxygen and nitrogen buffer system is composed of nitrogen buffer tank, precision filter, flow meter, pressure control valve, and venting parts. The nitrogen buffer tank is mainly used to balance the pressure and purity of nitrogen separated by the nitrogen-oxygen separation system to ensure the continuous supply of nitrogen. At the same time, after the adsorption tower is switched, part of the adsorption tower is backfilled with its own gas, which not only helps to boost the pressure of the adsorption tower, but also protects the bottom plate. , which plays a very important role in the adsorption tower. The working process of the device. Support roles.

4. The air buffer tank consists of an air buffer tank and ancillary valves and equipment. The air buffer tank reduces the pulsation of the air flow and acts as a buffer. This reduces system pressure fluctuations, allowing the compressed air to smoothly pass through the compressed air purification components, thoroughly removing impurities such as oil, water, and dust. It reduces the load on the oxygen and nitrogen separation system. At the same time, it not only provides a large amount of compressed air to the oxygen/nitrogen separation system when the adsorption tower is switched, which causes the pressure to rise sharply in a short time, but also the pressure in the adsorption tower rises sharply. Mechanical components such as working pressure, pressure swing, and pressure swing adsorption nitrogen production also ensure the reliable and stable operation of the equipment.
