The chemical industry uses nitrogen as a raw material for chemical reactions: nitrogen is required to be of high purity, generally 99.99% purity.
1. The raw material air is taken from nature, and nitrogen can be produced only by providing compressed air and power supply. The energy consumption of the equipment is low, and the operating cost is low.
2. The purity of nitrogen is easy to adjust, the purity of nitrogen is only affected by the amount of nitrogen exhaust, and the purity of ordinary nitrogen production can be adjusted arbitrarily between 95% and 99.99%; The high-purity nitrogen generator can be adjusted between 99% and 99.999%.
3. The equipment has a high degree of automation, fast gas production, and can be unattended. Start and shut down with just one button to press a button, and nitrogen can be generated within 10-15 minutes of turning on the machine.
4. The process flow of the equipment is simple, the structure of the equipment is compact, the area is small, and the equipment is adaptable.
5. The blizzard method is used to fill the molecular sieve to avoid the pulverization of the molecular sieve caused by the impact of high-pressure air flow, and to ensure that the molecular sieve can be used for a long time.
6. The digital flowmeter is a secondary instrument for industrial process monitoring with pressure compensation and high precision, and has the functions of instantaneous flow and cumulative calculation.
7. On-line detection of imported analyzer, high precision and maintenance-free.

Application of nitrogen generator in chemical industry
It is mainly used for chemical material gas, pipeline purging, atmosphere replacement, protective atmosphere, product transportation, etc. It is mainly used in chemical industry, spandex, rubber, plastics, tires, polyurethane, biotechnology, intermediates and other work. Many chemical works do not require high nitrogen purity, and many purities greater than 98% can be used.
Acrylic oxidation explosion-proof, float glass process, protect the chemical industry in the chemical process to create an oxygen-free atmosphere to improve the safety of the production process, fluid transportation power source and other displacement, cleaning, sealing, leak detection, dry quenching of protective gas; Catalyst regeneration, petroleum fractionation, chemical fiber production and other gas oil industry to improve petroleum processing and essence process, oil storage and oil and gas field well pressurization, pipeline cleaning and purging, solvent recovery, etc.
Nitrogen purification of storage, containers, catalytic cracking towers, pipelines, etc.; air pressure leak test of pipeline system, etc; offshore oil development; inerting of gas covering, nitrogen injection, storage tanks, containers, etc.
The glass manufacturing industry prevents surface oxidation and furnace cooling in the glass manufacturing process.
Gas protection during float glass production process to prevent oxidation of tin bath. shielding gas in the production process of float glass; float glass work In the production process of float glass, the float medium is very easy to oxidize at the high temperature of the tin bath, the loss of tin is added, and various defects occur on the glass plate, so it is necessary to introduce the protective gas nitrogen into the tin bath, and participate in 5% ~ 10% of the hydrogen together, and the tin bath constitutes a recovery atmosphere, so that the tin oxide is restored to tin from scratch.

Details
The energy-saving carbon molecular sieve nitrogen generator adopts an unequal pressure equalization process, while the traditional carbon molecular sieve nitrogen generator adopts an equal pressure equalization process. The benefits of pressure equalization are twofold: one is to reduce the impact of gas on the molecular sieve, and the other is to improve the utilization rate of compressed air.
We have improved the equalization position by using an unequal equalization process. During pressure equalization, the pressure equalization gas is led from the middle of the adsorption tower at the end of adsorption to the bottom of the adsorption tower at the end of desorption, and the mixed gas with high nitrogen purity in the middle of the adsorption tower is recovered to the desorption tower through the unequal pressure equalization structure, so as to improve the nitrogen concentration of the raw gas in the desorption tower, reduce the consumption of compressed air by the carbon molecular sieve in the desorption tower, improve the nitrogen production rate of the carbon molecular sieve, and achieve the effect of energy saving.
The performance of the dynamic adsorption capacity and separation coefficient of high-efficiency nitrogen production carbon molecular sieve determines the quality of nitrogen generator.

It should be noted that the laser cutting industry generally uses nitrogen pressure of 12 bar-16 bar, and a rear pressurization device is required.
PSA nitrogen generator uses air as raw material, carbon molecular sieve as adsorbent, uses the principle of pressure swing adsorption, and uses the method of selective adsorption of oxygen and nitrogen by carbon molecular sieve to separate nitrogen and oxygen, and produces nitrogen automatic equipment.
The carbon molecular sieve is based on the slight difference between the kinetic diameter of O2 and N2 to achieve the separation of nitrogen and oxygen, and the kinetic diameter of the oxygen molecule is small, so there is a faster diffusion rate in the micropores of the carbon molecular sieve. The kinetic diameter of the nitrogen molecule is larger, so the diffusion rate is slower, and the final enrichment from the adsorption column is high-purity nitrogen.
