NM series membrane separation nitrogen generator is composed of one or more membrane separators. When the clean compressed air passes through the polymer membrane, due to the difference in the solubility and diffusion coefficient of various gases in the membrane, the relative permeability of different gases in the membrane is caused rates are different.When the pressurized purified air is used as the gas source, the gas with relatively fast permeability, such as water, hydrogen, oxygen, carbon dioxide, etc., is enriched on the side of the membrane after passing through the membrane. while the gas with relatively slow permeation rate, gases such as nitrogen and argon are enriched on the retentate side of the membrane, thereby achieving the effect of separating the mixed gas. Nitrogen and other inert gases are enriched into high-purity gases for production use, while the enriched oxygen-enriched air on the permeate side is evacuated as waste gas. The nitrogen membrane uses this principle to separate nitrogen and oxygen in the air through multiple bundles of semi-permeable hollow fiber filaments made of polymer materials.

OP series pressure swing adsorption oxygen generator adopts advanced pressure swing adsorption technology, uses air as raw material, selects high-quality zeolite molecular sieve as adsorbent, based on the different adsorption rates of zeolite molecular sieve for oxygen and nitrogen, and under a certain pressure, carbon molecular The adsorption capacity of oxygen is much greater than that of nitrogen. Through the programmable program to control the opening and closing of the brake valve, pressurize the adsorption, decompress and desorb, and complete the separation of oxygen and nitrogen，Oxygen of the desired purity is obtained. Since the adsorbent has a certain adsorption capacity, it needs to be regenerated when the adsorption is saturated, so the adsorption of a single adsorption tower is intermittent. In order to ensure continuous gas supply, two towers are used to adsorb in parallel and alternately adsorbed. One tower works and the other regenerates, oxygen is produced continuously.

The carbon-supported nitrogen purification device can remove impurities such as oxygen, water, carbon dioxide, dust and other impurities in the general nitrogen of air separation. The device first uses a hydrogen-free deoxidizer-palladium carbon fiber to directly remove oxygen in nitrogen. The oxygen removal capacity is large, and the gas production cost is low. The principle is that the trace oxygen in the nitrogen reacts with the carbon in the deoxidizer to generate a trace amount of carbon dioxide, and the generated trace amount of carbon dioxide and the trace amount of water in the system are adsorbed by the desiccant, and then heated and regenerated after the adsorption is saturated. The two drying towers are used alternately, so that the whole system can work continuously. The nitrogen purification device adopts a medium-pressure purification process, which has the advantages of compact structure, simple operation, good purification effect and low energy consumption. The deoxidizer is designed to be replaced every two to three months, and the desiccant is circulated and regenerated in the device. The purification device is equipped with electrical control and instrument box, which can realize automatic control.
