Nitrogen generators produced by nitrogen generator manufacturers have the characteristics of three-stage catalysis, convenient operation, program control, low nitrogen production humidity, advanced technology, safety and reliability, etc. Of course, there are characteristics and faults, such as the nitrogen separated by the nitrogen generator is not pure. In the end, why wait, let me explain to you in detail.
First, Several characteristics of high-purity nitrogen generator
1. Three-stage catalysis, in addition to the two-stage catalysis in the electrolytic cell, there is also a third-stage catalysis. The catalyst is made of new precious metals, so that the oxygen content of the output nitrogen is less than 3ppm
2. It is easy to operate, saves the labor of transporting the cylinders, and saves the trouble of transferring the cylinders. The use is to turn on the power switch to produce nitrogen, which can be used continuously or continuously, and the nitrogen production is stable and not attenuated.
3. Program control. The control system of the high-purity nitrogen generator uses a special chip. All the working process is controlled by the program. Automatic constant pressure, constant flow, nitrogen flow can be fully adjusted according to the amount of 0-300ml/min.

4. Nitrogen production and low humidity. The ultra-high molecular weight permeation technology and effective dehumidification equipment are selected, thus reducing the original humidity and automatically draining the moisture after shutdown. The use of metal polymer dehumidification and two-stage adsorption greatly improves the purity of nitrogen.
5. Advanced technology: the electrolytic cell adopts vertical single liquid surface double cathode. Membrane separation technology, the catalytic layer uses PCAN carrier and precious metal catalyst, so that the electrolytic cell has high catalytic efficiency, large gas production, and high nitrogen purity. The situation is very stable.
6. Safe and reliable, equipped with equipment, flexible and reliable.
Second, The reason why the nitrogen gas separated by the nitrogen generator is not pure
1. Air output: the nitrogen generator must be below the rated value;
2. The working pressure of the adsorption tower: the general pressure is 0.7~0.8MPa;
3. Whether the testing instrument is accurate: whether the nitrogen analyzer is good or not, whether the sampling pipeline is leaking, etc.;
4. Molecular sieve: the service life of the molecular sieve of the nitrogen generator, whether it is invalid, and whether the molecular sieve in the adsorption tower has an authentic phenomenon.

5. The oil vapor in the air is easily adsorbed by the carbon molecular sieve, and it is difficult to desorb, filling the micropores and making the molecular sieve invalid. Although water is not fatal to carbon molecular sieve, it will add load to carbon molecular sieve, which will affect its adsorption of O2, CO2 and other gases, and then affect the purity of nitrogen.
6. Carbon molecular sieve: It is the center and key point of PSA nitrogen generator. Nitrogen production technology requires carbon molecular sieves with good strength, high nitrogen yield, and high argon purity and recovery. Of course, the quality and function of carbon molecular sieves are the key points, but the selection of carbon molecular sieves is also very elegant. It should be selected with uniform particles, high hardness, long service life and nitrogen production.
7. The description of the nitrogen generator is also very elegant. If the structure is not properly described, the molecular sieve will beat and rub against each other due to the impact of high-speed airflow, resulting in powder failure. A gas flow divider should be set at the bottom of the adsorption tower, and a compression device should be set at the top to effectively prevent this phenomenon from occurring.
