Electronic industry nitrogen machine principle
Nitrogen making machine is based on the principle of pressure swing adsorption, the use of high-quality carbon molecular sieve as an adsorbent, under a certain mechanical effect, oxygen in the carbon molecular sieve micropore diffusion rate is much greater than nitrogen, in the adsorption does not reach balance, nitrogen is enriched in the gas phase, the formation of finished nitrogen. Then reduce the pressure to normal pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower adsorbed nitrogen, the other tower desorption regeneration, through the PLC program automatic control, so that the two towers alternately cycle to achieve the purpose of continuous production of high quality and high purity nitrogen. Under pressure, the purified and dry compressed air is subjected to pressure adsorption and decompression desorption in the adsorber.
2, nitrogen machine technical indicators
(1) Flow: 1-3000nm3 /h
(2) Purity: 95%-99.9995%
(3) Dew point: ≤-45℃ (under normal pressure)
(4) Pressure: 0.3-0.8Mpa adjustable
3, equipment characteristics
(1) Mechanical and electrical integration design to achieve automated operation:
Imported PLC control imported pneumatic valve automatic operation, can achieve unattended. The nitrogen purity is continuously displayed, and the nitrogen flow and pressure are adjustable.
(2) Nitrogen production is convenient and fast:
Advanced technology, unique air flow distributor, make the air flow distribution more uniform, efficient use of carbon molecular sieve, about 30 minutes to provide qualified nitrogen.
(3) Easy to use:
Equipment structure is compact, the whole skid, occupying a small area without infrastructure investment, less investment, the field only need to connect the power supply to produce nitrogen.
(4) More economical than other nitrogen supply methods:
Industrial nitrogen machine is a simple nitrogen production method, using air as raw material, energy consumption is only the electric energy consumed by air compressor, with low operating cost, low energy consumption, high efficiency advantages.
(5) Wide range of applications:
Protective gas for metal heat treatment process, chemical industry production gas and all kinds of storage tanks, pipelines filled with nitrogen purification, rubber, plastic products production gas, food industry oxygen preservation packaging, beverage industry purification and covering gas, pharmaceutical industry filled with nitrogen packaging and containers filled with nitrogen and oxygen, electronic industry electronic components and semiconductor production process protection gas.
