制氮机原理流程
变压吸附技术（Pressure Swing Adsorption,简称PSA技术）：是一种先进的气体分离技术，以吸附剂（多孔固体物质）内部表面对气体分子的物理吸附为基础，利用吸附剂在一定压力下对不同气体的吸附量不同的特性来实现气体的分离。
(Pressure Swing Adsorption) is an advanced gas separation technology,based on the physical adsorption of the internal surface in the adsorbent to the gas molecules,separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure.
碳分子筛是实现氮氧分离，从空气中提取氮气的吸附剂，在吸附压力相同时，碳分子筛对氧的吸附量大大高于对氮的吸附量。
PSA制氮，也称为碳分子筛制氮，正是利用这一原理，以空气为原材料，以碳分子为吸附剂，运用变压吸附原理，利用碳分子筛对氧和氮的选择性吸附，实现空气中的氮和氧分离，生产出氮气。
The CMS(carbon molecular sieve)is adsorbent picked up from the air,used in separating oxygen and nitrogen molecular.the adsorption quantity of CMS is greatly higher to oxygen than nitrogen does with the same pressure...
PSA nitrogen generator produces N2 gas,using air as raw materials and carbon molecular sieve as adsorbent,by the selective adsorption of carbon molecular sieve to O2 and achieving the separation of the N2 and O2 in the air.
