Working principle of membrane nitrogen generator

Membrane nitrogen generator manufacturers: Hangzhou Scala Filtration Technology Co., Ltd. was established in 2013, specializing in compressed air purification and air separation technology, and is the authorized agent of Noblegen Cryogenics products in the UK.
Noblegen Cryogenics is a subsidiary of Wirac Automation Ltd, UK, with its headquarters and production base in Gateshead, UK. It is an innovative manufacturer of electrical control systems. Its products have an important position in the global market. The production of liquid nitrogen ranges from 10 liters per day to 550 liters per day.
TRITON2 and LN series products are a unique product from Noblegen Cryogenics in the United Kingdom, based on advanced GM (Gifford-McMahon) cold head and helium compressor design, and high purity from PSA (pressure swing adsorption) nitrogen generator The nitrogen is cooled to 77K (-196°C) to produce liquid nitrogen. The whole system is controlled by the touch screen and dynamically displays the liquid level in the Dewar tank, the PSA nitrogen production process and various trend charts in real time.
Traditional scientific research laboratories rely on bottled liquid nitrogen. The rising cost and safety issues in liquid nitrogen transportation and storage have long plagued users. Using Noblegen's on-site liquid nitrogen generator can end the traditional liquid nitrogen supply method, and it is reliable Sexuality and economy have been widely recognized in the global market.
The working principle of the membrane nitrogen generator is that because of the pressure difference between the two sides of the membrane, different gases pass through the membrane at different rates. Our hollow fiber membrane is composed of porous polymer fibers, and the separated gas diffuses out through the surface of the membrane.
The inside of the hollow fiber membrane is connected by many small columnar polymer fibers, and the gas to be separated passes through these polymer fibers under pressure. Because the pressure inside and outside the hollow fiber membrane is different, the passing speed of different gases is different, so as to achieve the purpose of gas separation. "Fast gas" (such as hydrogen, carbon dioxide, oxygen, water vapor, etc.) passes through the membrane at a fast rate and can easily permeate through the permeation port of the membrane. "Slow gas" (such as carbon monoxide, nitrogen, methane, hydrocarbons, etc.) passes through The rate of the membrane is slow, and it is enriched on the outlet side of the membrane, so as to achieve the purpose of separating nitrogen.
