Considering the technical level and economy of the existing nitrogen generator, pressure swing adsorption (PSA) is adopted for nitrogen production, and Takeda high-performance carbon molecular sieve is selected as the adsorption material. The purity of nitrogen is 99.99% (oxygen free content specified in the standard), which is directly obtained from compressed air. The equipment has the advantages of simple composition, small floor area, simple operation and maintenance and low failure rate. Low energy consumption and low equipment operation cost;

为保证变压吸附式氮气发生器长期、稳定、正常运行，压缩空气在进入氮气发生器前必须进行除尘、除水、除油等净化处理，以满足氮气发生器对压缩空气质量的要求。因此我们在冷干机、过滤器选型上，均选用国内知名，保证整个系统长期稳定运行；

In order to ensure the long-term, stable and normal operation of PSA nitrogen generator, the compressed air must be subject to dust removal, water removal, oil removal and other purification treatment before entering the nitrogen generator, so as to meet the requirements of nitrogen generator for compressed air quality. Therefore, we select domestic well-known brands in the selection of cold dryer and filter to ensure the long-term stable operation of the whole system;

为保证整个制氮系统长期可靠运行，变压吸附制氮机主要部件如分子筛、阀门、控制器等均采用进口产品。保证设备质量和整个系统的、长期、可靠运行；

In order to ensure the long-term and reliable operation of the whole nitrogen generation system, the main components of PSA nitrogen generator such as molecular sieve, valve and controller are imported products. Ensure equipment quality and safe, long-term and reliable operation of the whole system;

变压吸附制氮机的特点是氮气流量与纯度有一定的关系。使用的流速越高，氮气纯度越低；使用的流速越低，氮气纯度越高。用户可根据使用情况调节流量和纯度；

The characteristic of PSA nitrogen generator is that there is a certain relationship between nitrogen flow and purity. The higher the flow rate used, the lower the purity of nitrogen; The lower the flow rate used, the higher the purity of nitrogen. Users can adjust the flow and purity according to the use situation;

制氮机运行由PLC控制，设备自动运行，生产合格氮气。该设备操作简单，无人值守。

The operation of the nitrogen generator is controlled by PLC, and the equipment operates automatically to produce qualified nitrogen. The equipment is easy to operate and unattended.
