为什么制氮机前面要加缓冲罐?

PSA制氮机，其实也可以叫碳分子筛制氮机。常用于化工、石油天然气、食品、制药等行业。其主要组成部分为：压缩空气净化系统、空气储罐系统、氧氮分离系统、氮气缓冲系统和电气控制系统。

PSA nitrogen generator can also be called carbon molecular sieve nitrogen generator. Commonly used in chemical industry, oil and gas, food, pharmaceutical and other industries. Its main components are: compressed air purification system, air storage tank system, oxygen nitrogen separation system, nitrogen buffer system and electrical control system.

为什么制氮机前面要加缓冲罐?

Why add buffer tank in front of nitrogen generator?

缓冲罐具有降低气脉流动，起缓冲的作用。从而减小系统压力波动,使压缩空气平稳通过压缩空气净化组件，以便充分除水等杂质，减轻后续制氮机氧氮分离系统的负荷。

The buffer tank has the function of reducing gas flow and buffering. So as to reduce the pressure fluctuation of the system, make the compressed air pass through the compressed air purification component smoothly, so as to fully remove water and other impurities, and reduce the load of the oxygen nitrogen separation system of the subsequent nitrogen generator.

同时，在吸附塔进行工作切换时，也为制氮机装置提供短时间迅速生涯所需的大量压缩空气，使吸附塔内的压力很快上升到工作压力，保证设备可靠稳定的运行。

At the same time, during the work switching of the adsorption tower, a large amount of compressed air is also provided for the nitrogen generator, which makes the pressure in the adsorption tower rise to the working pressure quickly and ensures the reliable and stable operation of the equipment.

氮气缓冲罐用于均衡从氧氮分离系统分离出来的氮气压力的压力和纯度保证连续供给氮气稳定，同时,在吸附塔进行工作切换后,它将本身的部分气体回充吸附塔；一方面帮助吸附塔升压,另外也起到保护床层的作用，在制氮机设备工作中起到了其重要的工艺辅助作用。

The nitrogen buffer tank is used to balance the pressure and purity of nitrogen pressure separated from the oxygen nitrogen separation system to ensure the continuous supply of nitrogen is stable. At the same time, after the working switch of the adsorption tower, it will recharge part of its own gas to the adsorption tower; On the one hand, it helps to boost the pressure of the adsorption tower, on the other hand, it also plays the role of protecting the bed, which plays an important auxiliary role in the work of nitrogen generator equipment.
