為什么制氮機前面要加緩沖罐?

PSA制氮機，其實也可以叫碳分子篩制氮機。常用于化工、石油天然氣、食品、制藥等行業(yè)。其主要組成部分為：壓縮空氣凈化系統(tǒng)、空氣儲罐系統(tǒng)、氧氮分離系統(tǒng)、氮氣緩沖系統(tǒng)和電氣控制系統(tǒng)。

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.

為什么制氮機前面要加緩沖罐?

Why add buffer tank in front of nitrogen generator?

緩沖罐具有降低氣脈流動，起緩沖的作用。從而減小系統(tǒng)壓力波動,使壓縮空氣平穩(wěn)通過壓縮空氣凈化組件，以便充分除水等雜質，減輕后續(xù)制氮機氧氮分離系統(tǒng)的負荷。

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.

同時，在吸附塔進行工作切換時，也為制氮機裝置提供短時間迅速生涯所需的大量壓縮空氣，使吸附塔內的壓力很快上升到工作壓力，保證設備可靠穩(wěn)定的運行。

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.

氮氣緩沖罐用于均衡從氧氮分離系統(tǒng)分離出來的氮氣壓力的壓力和純度保證連續(xù)供給氮氣穩(wěn)定，同時,在吸附塔進行工作切換后,它將本身的部分氣體回充吸附塔；一方面幫助吸附塔升壓,另外也起到保護床層的作用，在制氮機設備工作中起到了其重要的工藝輔助作用。

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.
