Our company has carefully designed and arranged the complete nitrogen production system, and the complete nitrogen production device includes the following parts. Air compressor air purification device Air storage tank oxygen and nitrogen separation system nitrogen buffer tank 1. The air compressor is the main part of the air supply, and the compressed air is first passed into the compressed air purification module to remove water and oil, and then into the air purification module 2. Air purification device Air purification component is composed of high efficiency filter, freeze dryer, fine filter, super fine filter, catalyst oil separator, etc., compressed air into the pipeline filter to remove > 1μm particles and most of the water, to ensure the normal use of the freeze dryer and the filter after the freeze dryer to force cooling to about 5℃, The water vapor in the air condenses into water, which is separated and filtered through the water separation filter, and discharged by the sewage valve, so that the dew point of the compressed air reaches -10℃, the fine filter filters > 0.01μm particles and oil and water, and then enters the super-fine filter to filter oil and water; Filtration accuracy > 0.001μm, after the active carbon in the oil remover adsorption residual trace oil mist, get clean compressed air through the pipeline into the nitrogen oxygen separation system, to ensure the longevity of molecular use. 3. Air storage tank components The role of the air storage tank is to ensure the smooth use of gas in the system, reduce the airflow pulsation, play a buffer role, so as to reduce the system pressure fluctuations, so that the compressed air smoothly through the compressed air purification system, in order to fully remove oil and water impurities, reduce the subsequent PSA oxygen and nitrogen separation device load. At the same time, when the oxygen and nitrogen separation system performs periodic work switching, it also provides a large amount of compressed air required for rapid pressure increase in a short time for the oxygen and nitrogen separation system, so that the adsorption pressure in the adsorption tower quickly rises to the working pressure, ensuring the stable operation of the equipment. 4. Oxygen nitrogen separation system Oxygen nitrogen separation system is the core part of the nitrogen machine, composed of two adsorption tower, compression device, program control valve, and other components, our hospital adopts high-quality imported valves, no leakage service life of more than 3 million times, providing reliable performance guarantee for the whole device. 5. Nitrogen buffer tank Nitrogen buffer tank is mainly composed of buffer tank, dust filter, flow meter, pressure regulator, throttle valve, etc., to provide a stable nitrogen source on site. Summary: Through the above analysis of the scheme, we can have a certain understanding and understanding of the structure and composition of the nitrogen machine, but for different environmental conditions and different process conditions, the equipment will have a certain selectivity in the configuration.
