High-purity nitrogen generator working system is stable and efficient
The high-purity nitrogen generator uses a high-quality carbon molecular sieve as an adsorbent according to the principle of pressure swing adsorption. Under certain pressure, due to the kinetic effect, the diffusion rate of oxygen in the pores of carbon molecules is much larger than that of nitrogen. When the adsorption does not reach equilibrium, oxygen is adsorbed by carbon molecular sieves in large quantities, and nitrogen molecules are enriched in the gas phase to achieve oxygen-nitrogen separation. Since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, the pressure is reduced, and the oxygen molecules adsorbed by the carbon molecular sieve can be desorbed, and the carbon molecular sieve can be regenerated and reused. The high-purity nitrogen generator adopts a double-tower structure. One tower adsorbs nitrogen and one tower desorbs and regenerates. The PLC intelligent program controller controls the opening and closing of the pneumatic angle seat valve, so that the two towers alternate and continuously produce nitrogen.
High-quality components are stable and reliable. The key components such as pneumatic valves and electromagnetic pilot valves are imported. The operation is reliable, the switching speed is fast, the service life is more than one million times, the failure rate is low, the maintenance is convenient, and the maintenance cost is low.
Unqualified nitrogen automatic emptying system, the low-purity nitrogen in the initial stage of the automatic discharge is automatically emptied, and the gas is delivered after reaching the target.
The ideal purity selection range, nitrogen purity adjustment can be adjusted according to the user's needs between 79% and 99.999%, plus a unique purification technology in the latter stage in series with a nitrogen purifier, can obtain 99.9995% high purity nitrogen .

Nitrogen purity, flow monitoring:
In the control room, the working state of the air compressor, the cold dryer, the pressure swing adsorption nitrogen generator, the working state of the program control valve, the whole process flow diagram, the gas source pressure, the adsorption pressure, the finished nitrogen gas are monitored between the manipulator interface of the industrial computer. Export pressure, finished product nitrogen purity, flow rate, and authorization modification of the above data, through the program to set the above data for review, view historical records.
High Purity Nitrogen Generator is one kind of skid nitrogen can produce nitrogen with purity up to 99.9999%. This nitrogen generator includes one 99.5% purity nitrogen generator and one 99.999% purity nitrogen purifier. It is a good way to achieve high purity nitrogen with low energy consumption. It is easy for ocean transportation, no need for site installation. When machine reach site, just need to put the machine on flat ground, connect power and gas pipeline, then one simple push on starting button makes the nitrogen generator begin to work.
Step one: 99.5/99.9% purity nitrogen generator
This nitrogen generator is the standard nitrogen generator supplied by Gamma. It has air compressor, air treatment part, air tank, nitrogen separator and nitrogen buffer tank. It is normally installed on one skid, so this nitrogen generator is also called skid nitrogen generator. After this purity nitrogen is produced, the nitrogen goes to nitrogen purifier.
Step two: nitrogen purifier
The principle of nitrogen purifier is adding hydrogen or carbon to the produced nitrogen. In this way, the oxygen acts with hydrogen to generator water and oxygen is removed. Chemical formula is as
During the process of removing
oxygen, water will be generated. In order to reduce the dew point of produced
nitrogen, there are cooler, adsorption dryer, filtration dust removal devices
in the system, used to remove water, dust, etc to get high purity clean
