制氮机在化工反应釜领域的应用

反应釜的广义理解即有物理或化学反应的容器，通过对容器的结构设计与参数配置，实现工艺要求的加热、蒸发、冷却及低高速的混配功能。反应釜广泛应用于石油、化工、橡胶、染料、医药、食品等行业，是用来完成硫化、硝化、氢化、烃化、聚合、缩合等工艺过程的压力容器，例如反应器、反应锅、分解锅、聚合釜等；其材质一般有碳锰钢、不锈钢、锆、镍基（哈氏、蒙乃尔、因康镍）合金及其它复合材料。

The general understanding of the reactor is the container with physical or chemical reaction. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be realized. Reactor is widely used in petroleum, chemical, rubber, dyestuff, medicine, food and other industries. It is a pressure vessel used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactor, reaction pot, decomposition pot, polymerizer, etc. its materials generally include carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel, Inconel) alloy and others compound material.

有一些产品在生产过程中会被氧化，结晶，会有爆炸的危险，这个时候用氮气这种惰性气体做为保护气主要就是为了防氧化和防爆。

Some products will be oxidized and crystallized in the production process, and there is a risk of explosion. At this time, nitrogen, an inert gas, is mainly used as protective gas to prevent oxidation and explosion.

市面上的瓶装氮气和液氮都比较昂贵且费心费力费时，使用PSA制氮机是比较好的选择。PSA制氮机以取之不竭用之不尽的空气为原料，以碳分子筛作为吸附剂，运用变压吸附原理，利用碳分子筛对氧和氮的选择性吸附而使氮和氧分离。

Bottled nitrogen and liquid nitrogen on the market are expensive and time-consuming, so PSA nitrogen generator is a better choice. PSA nitrogen generator uses inexhaustible air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption principle, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen.

与传统制氮法相比，它具有工艺流程简单、自动化程度高、产气快(15～30分钟)、能耗低、氮气纯度在线检测，操作维护方便、运行成本较低、装置适应性较强等特点。PSA制氮机是一次投资永久用气，一键开机，实现无人职守，可以节省人工，节省成本。

Compared with the traditional nitrogen production method, it has the advantages of simple process, high degree of automation, fast gas production (15-30 minutes), low energy consumption, on-line detection of nitrogen purity, convenient operation and maintenance, low operation cost and strong adaptability. PSA nitrogen machine is a permanent investment in gas, a key boot, unattended, can save labor, save costs.
