PSA oxygen generator Industrial oxygen mainly in the form of pressure swing adsorption, is a low pressure adsorption vacuum desorption oxygen equipment, also referred to as VPSA oxygen generator. The use of impurities and the formation of nitrogen pressure swing adsorption oxygen molecular sieve desiccant, the selective adsorption of carbon dioxide and water in the mixed bed in the air, the accumulation and collection of oxygen at the end of the bed, and the desorption of the adsorption saturated molecular sieve bed under vacuum conditions, thus recycling the purity of oxygen (90 ~ 95%).

Pressure swing adsorption (PSA pressure swing adsorption oxygen production equipment), oxygen equipment, is a new type of separation technology, molecular sieve adsorption materials as an example, the principle is to use molecular sieve different gas molecules adsorption performance differences and separation of gas mixtures. It is based on air as raw material, using an efficient solid adsorbent to select adsorption properties, high selection on nitrogen and oxygen nitrogen and oxygen separation from the air. Molecular sieves selectively adsorbed based on their internal cavity size, the adsorption of molecules of a certain size is the exclusion of large molecules of matter. Therefore, the gas phase can be enriched with oxygen. After a period of time, nitrogen equilibrium molecular sieve adsorption, according to the adsorption characteristics of the gas zeolite molecular sieve under different pressures to reduce the nitrogen zeolite molecular sieve desorption pressure, this process is called regeneration. Pressure swing adsorption method usually uses two towers in parallel, pressure swing adsorption, decompression and regeneration, so as to obtain a continuous flow of oxygen.

工作原理

VPSA制氧机主要由风机，真空泵，冷却器，吸附系统，氧气缓冲罐，控制系统。

1，鼓风机和真空泵：为整个系统提供原风机，根据真空变压吸附装置的设计条件，结合用户使用情况，选择与设计条件下送风排气压力。真空泵要确保正常分析整个系统，使系统在理想的真空状态，使整个装置可连续氮氧生产工作。？

2，冷却风机：压缩空气的高温高压，空气温度下降到操作所需的水冷却器后的温度，吸附到吸附塔。

3，吸附系统的吸附系统由二一沸石分子筛吸附剂的吸附塔、管道、阀门等部件。低温和高压压缩空气从底部进入一个塔，通过吸附层，氮，空气中的二氧化碳，水蒸气的吸附。氧吸附床在吸附塔顶部作为产品气输出。同时，B柱再生条件，当吸附塔吸附达到饱和，在控制系统的调节下，高压空气温度变成B塔开始吸附氧的生产。A，B塔等交替实现连续制氧目的。？

4，氧气缓冲罐：商店的产品气体（氧气），对成套设备的调节作用。

5，控制系统：工程师将预先写好的阀控制程序输入到PLC控制器，打开和关闭阀，电磁阀通过调节气体的吸附系统，在指定的时间之后，吸附，再生。

PSA制氧机主要由压缩机，冷干机，除油，吸附系统，氧气缓冲罐，控制系统。

1：空气压缩机，空气压缩机，为整个系统提供空气，根据变压吸附制氧设备生产，空气压缩机的选择符合天然气供应的设计条件。

2，冷干机：原料空气压缩机空气加压，高温度和压缩空气为冷干机的冷却，干燥，除去杂质，压力高，得到的低温和高压压缩空气。

3，除油：油器低温在去除油雾的压缩空气压力高，防止在沸石分子筛的影响生活的空气油雾。

4，吸附系统的吸附系统由二一沸石分子筛吸附剂的吸附塔、管道、阀门等部件。低温和高压压缩空气从底部进入一个塔，通过吸附层，氮，空气中的二氧化碳，水蒸气的吸附。氧吸附床在吸附塔顶部作为产品气输出。
