Working principle of nitrogen machine

The nitrogen machine is based on the principle of pressure swing adsorption, the use of carbon molecular sieve adsorption is high quality, under pressure, to prepare nitrogen from the air. Clean dry compressed air, pressure swing adsorption, desorption in adsorption vacuum. Due to aerodynamics, oxygen of carbon molecular sieve is much greater than the diffusion rate of nitrogen in micropores, oxygen is preferred to adsorb carbon molecular sieve, and nitrogen is enriched in the gas phase to form a complete nitrogen. Then decompression to atmospheric pressure, adsorption of oxygen and other impurities desorption adsorption, to achieve regeneration. The whole system is composed of the following parts: compressed air purification module, gas storage tank, oxygen and nitrogen separation device, nitrogen buffer tank. Production machine RD series nitrogen nitrogen machine nitrogen is based on the principle of pressure swing adsorption, the use of high-quality carbon molecular sieve adsorption carbon molecular sieve, from the pressure of the air system, nitrogen machine pressure swing adsorption carbon molecular sieve nitrogen from the dry compressed air, purification pressure swing adsorption, adsorption bed decompression desorption. Due to aerodynamics, in carbon nitrogen oxygen. The whole system is composed of the following parts: compressed air purification module, gas storage tank, oxygen and nitrogen separation device, nitrogen buffer tank. 1, compressed air purification component, compressed air purification component in the compressed air first into the compressed air purification component, compressed air from the pipeline filter to remove most of the oil, water, dust, and then through the freeze dryer to further remove water, fine filtration of oil, dust, and then in the depth of purification of ultra-precision filter. According to the system condition, Reed specially designed a set of compressed air oil separator, used to prevent possible trace oil permeability, provide adequate protection, carbon molecular sieve. The rigorous design of the air ensures the durability of the carbon molecular sieve purification components. The rigorous design of the air ensures the durability of the carbon molecular sieve purification components.

Clean air after assembly process can be used for instrument air. The function of the gas storage tank is: reduce the flow pulsation, buffer; Thus, the pressure fluctuation of the system is reduced, so that the compressed air passes smoothly through the compressed air purification component, so as to fully remove the impurities in the water and reduce the load of the subsequent PSA oxygen and nitrogen separation device. At the same time, in the working conversion of the absorption tower, it also provides a large number of compressed air PSA oxygen nitrogen separation equipment in a short time, so the pressure in the absorption tower quickly rises to the working pressure to ensure the reliable and stable operation of the equipment. At the same time, in the working conversion of the absorption tower, it also provides a large number of compressed air PSA oxygen nitrogen separation equipment in a short time, so the pressure in the absorption tower quickly rises to the working pressure to ensure the reliable and stable operation of the equipment.

Oxygen nitrogen separation unit,  equipped with a special carbon molecular sieve adsorption tower in which the carbon molecular sieve consists of one and two. When clean compressed air enters the inlet end of the carbon molecular sieve column to the outlet of the carbon molecular sieve process, O2, CO2 and H2O are adsorbed and exported through the nitrogen adsorption column.

After some time, the carbon molecular sieve adsorbed saturation tower. After some time, the carbon molecular sieve adsorbed saturation tower. At this time, a tower automatically stops adsorption and compressed air enters the oxygen and nitrogen production of Tower B for molecular sieve regeneration tower. Molecular sieve regeneration is the removal of adsorbed O2, CO2 and H2O by rapid descent to atmospheric pressure via adsorption column. The two towers alternately adsorbed and regenerated to complete the separation of oxygen and nitrogen and the continuous output of nitrogen. These processes are controlled by a programmable logic controller (PLC). These processes are controlled by a programmable logic controller (PLC). When the purity of nitrogen at the outlet is set, the PLC program, the automatic exhaust valve is opened, and the unqualified nitrogen is automatically drained to ensure that the unqualified nitrogen does not flow. When using the engine mu exhaust
