制氮机常见隐患及解决方案

制氮机可分为深冷制氮、膜分离制氮和分子筛制氮3种方式，均采用物理方法从空气中制取氮气。瑞气所生产的制氮机采用分子筛的方式，以碳分子筛为吸附剂，从空气中分离出氮气。由于制氮机属于机械设备，在使用中如若操作不当也会产生隐患，主要分为操作不当造成的机械伤害以及气体伤害，下面从以上两点出发对以上问题进行详细介绍，希望用户在使用中可以避免以下问题的出现。

Nitrogen generator can be divided into three ways: cryogenic nitrogen generator, membrane separation nitrogen generator and molecular sieve nitrogen generator, all of which use physical methods to produce nitrogen from air. The nitrogen generator produced by Ruiqi uses molecular sieve as adsorbent to separate nitrogen from air. As the nitrogen machine belongs to mechanical equipment, improper operation in use will also produce potential safety hazards, which are mainly divided into mechanical injury and gas injury caused by improper operation. The following is a detailed introduction to the above problems from the above two points, hoping that users can avoid the following problems in use.

1、由于制氮设备的PLC有可能被误操作启动。在养护工作开始前，一定关闭整个制氮设备的总电源。

1. Because the PLC of nitrogen making equipment may be started by misoperation. Be sure to turn off the main power supply of the whole nitrogen making equipment before maintenance.

   
   

2、由于整个制氮系统中气体均是带压的，需防止压力气体的加渣冲击；在空压机、冷干机、气体干燥设备、制氮主机及氮气纯化装置等设备的排气口，请勿站人。整个系统中的连接管路必须牢固可靠密封，经过设备销售商确认可靠，以免漏气或造成管路破裂，发生人员伤亡或财物损坏。

2. As the gas in the whole nitrogen production system is under pressure, it is necessary to prevent the slag impact of pressure gas; do not stand at the exhaust ports of air compressor, cold dryer, gas drying equipment, nitrogen production host and nitrogen purification device. The connecting pipeline in the whole system must be firmly and reliably sealed and confirmed by the equipment seller to avoid air leakage or pipeline rupture, casualties or property damage.

3、制氮设备排放出的废气为浓缩氧气，容易引起火灾。须严禁火源。

3. The exhaust gas from nitrogen plant is concentrated oxygen, which is easy to cause fire. Fire sources must be strictly prohibited.

4、高纯氮气作为隔绝空气或氧气等气体的惰性气体，在密封环境中容易使人缺氧窒息。使用时，人员必须处于通风良好的环境中，人或动物切勿在充满高纯氮气的密封环境中，以免发生伤亡事故。

4. As an inert gas to isolate air or oxygen, high purity nitrogen is easy to cause hypoxia and suffocation in a sealed environment. When using, personnel must be in a well ventilated environment, and people or animals must not be in a sealed environment filled with high purity nitrogen, so as to avoid casualties.

5、由于整个制氮系统中要使用380V或220V动力电源，请注意用电！非人员或未经许可和培训的其他人员切勿擅自操作电器或擅改电路。

5. As the whole nitrogen system to use 380V or 220V power supply, please pay attention to electricity safety! Non personnel or other personnel without permission and training are not allowed to operate electrical appliances or change the circuit without authorization.
