Working Principle Description:
Carbon molecular sieve can adsorb oxygen and nitrogen in the air at the same time, and its adsorption capacity also increases with the increase of pressure, and there is no obvious difference in the equilibrium adsorption capacity of oxygen and nitrogen under the same pressure. Therefore, it is difficult to complete the effective separation of oxygen and nitrogen only by the change of pressure. If the adsorption rate is further considered, the adsorption characteristics of oxygen and nitrogen can be effectively distinguished. The diameter of oxygen molecule is smaller than that of nitrogen molecule, so the diffusion speed is hundreds of times faster than that of nitrogen.
Therefore, the adsorption speed of carbon molecular sieve is also very fast, and the adsorption reaches more than 90% in about one minute: at this time, the adsorption capacity of nitrogen is only about 5%, so at this time, the adsorption is basically oxygen, and the rest is mostly nitrogen. In this way, if the adsorption time is controlled within 1 minute, oxygen and nitrogen can be preliminarily separated, that is to say. Adsorption and desorption are realized by pressure difference.
When the pressure increases, adsorption and desorption occur when the pressure decreases. The difference between oxygen and nitrogen is achieved by controlling the adsorption time. The time is controlled very short, oxygen has been fully adsorbed, and nitrogen has not been adsorbed, so the adsorption process is stopped. Therefore, pressure swing adsorption nitrogen production should have pressure change, and the time should be controlled within 1 minute.
Automatic adjustment of rated flow and product gas purity on PSA nitrogen generator can achieve different requests.
Nitrogen, commonly referred to as inert gas, is used in some inert atmospheres for metal treatment and in bulbs to prevent arcing, but it is not chemically inert. It is an essential element in animal and plant life and an integral part of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. A small amount of nitrogen in steel will inhibit grain growth at high temperature and improve the strength of some steels. It can also be used to produce a hard surface on steel. Nitrogen can be used to produce ammonia, nitric acid, nitrate, cyanide, etc; In the manufacture of explosives; Filled high temperature thermometer, incandescent bulb; Form inert material to preserve the material and use it in a drying oven or glove bag. Liquid nitrogen during food freezing; As a coolant in the laboratory.
