Although we don't touch the nitrogen generator, we should be very familiar with it. When we manufacture nitrogen, the tool we often use is the nitrogen generator. So what technology does the nitrogen generator use?
PSA air separation nitrogen generator is the most advanced gas separation technology at present. It uses high-quality imported carbon molecular sieve as adsorbent and PSA principle at room temperature to prepare high-purity nitrogen through separation air. The dispersion rate of oxygen and nitrogen molecules on the zeolite surface is different. The gas molecules with small diameter have higher dispersion rate and more people enter the micropore of carbon zeolite. The gas molecules with large diameter have lower dispersion rate and less people enter the micropore of carbon zeolite. The selective adsorption capacity of carbon zeolite for nitrogen and oxygen is poor, which leads to the enrichment of oxygen in the adsorption phase and nitrogen in the gas phase in a short time Under the condition of PSA, the enriched nitrogen can be obtained.
After the nitrogen generator works in stages, the adsorption of oxygen on the molecular sieve reaches equilibrium. According to the different adsorption capacity of carbon molecular sieve on the adsorbed gas under different pressures, reducing the pressure can prevent the carbon molecular sieve from adsorbing oxygen, which is a regeneration process. According to the different regeneration pressure, it can be divided into vacuum regeneration and atmospheric regeneration. Atmospheric pressure regeneration is conducive to the complete regeneration of molecular sieve, and it is easy to get high purity gas.
The normal nitrogen with a certain flow rate and purity of the nitrogen generator and the gas of the hydrogen nitrogen generator enter into the installation and configuration together. After fully mixing in the mixer, it enters into the installation and configuration of the deaerator installed with palladium catalyst. The chemical reaction of 2h2 + O2 = 2H2O occurs under the result of the deoxidation catalyst to achieve the goal of deoxidation. After deoxidation, the water of the nitrogen generator is dehydrated by the cooler all the time, and the nitrogen generator enters the monotone of the monotone one after another. When the nitrogen generation point reaches about - 60 ℃, the monotone is equipped with 2 sets, in which the monotone is used for adsorption monotone, and the other one is used for regeneration, which is used for pre adjustment of the adsorption filter in the next cycle. The monotone of the nitrogen generator is finally high.
