Domestic nitrogen generator is an advanced gas separation technology that uses imported carbon molecular sieve as adsorbent and adopts pressure swing adsorption principle to separate air at room temperature and generate high-purity nitrogen.
Domestic nitrogen generator palladium catalyst deoxygenation purification:
The flow rate and purity of nitrogen and hydrogen enter the equipment simultaneously. After thorough mixing in the mixer, they enter the palladium catalyst deoxygenator equipped in the equipment, and the reaction 2H2+O2=2H2O occurs under the action of the deoxygenation catalyst to achieve the purpose of deoxygenation. After dehydration in the nitrogen cooler, it continues to enter the drying nitrogen. The nitrogen dew point reaches 60 degrees Celsius. There are two dryers, one is an adsorption dryer, and the other is a water-saturated dryer for regeneration, preparing for the next cycle of absorption. After drying, the nitrogen passes through a filter for dust removal, and the final result is high-purity nitrogen.
Pressure swing adsorption nitrogen generator (referred to as PSA nitrogen generator) is a nitrogen generation equipment designed and manufactured according to pressure swing adsorption technology.
Usually, two adsorption towers are used in parallel, and the fully automatic control system strictly controls the timing according to a specific programmable sequence, alternately performing pressurized adsorption and depressurized regeneration to complete nitrogen-oxygen separation and obtain the required high-purity nitrogen.
Regarding the classification of nitrogen generators, you can refer to the article "Principle of Nitrogen Generator" for corresponding understanding. Secondly, observe the appearance and structure of the instrument itself:
Liquid-added nitrogen generators have a water level indicator on the front. Membrane separation nitrogen supply device AYAN-20LG oxygen-nitrogen separation generator, while nitrogen generators without water addition do not need this at all. It actually also has a drainage device. After a period of work, a certain amount of water can be discharged from this outlet;
In addition, compared to nitrogen generators without liquid addition, liquid-added nitrogen generators have an additional flow display on the device;
But in fact, this display is mostly just a simulated flow to make the instrument look more beautiful. If this device is actually added, its price would not be cheaper than the instrument itself.
The change curves of oxygen and nitrogen adsorption capacity of carbon molecular sieve under different pressures and times:
After a period of time, the adsorption of oxygen by the molecular sieve reaches equilibrium. According to the different adsorption characteristics of carbon molecular sieve for adsorbed gases under different pressures, reducing the pressure reduces the adsorption of oxygen by the carbon molecular sieve, i.e., regeneration. Depending on the regeneration pressure, it can be divided into vacuum regeneration and atmospheric pressure regeneration. Atmospheric pressure regeneration is beneficial for the regeneration of the molecular sieve and makes it easy to obtain high-purity gas.
