In the industrial production process, poisonous, hazardous, flammable, explosive, volatile materials require inert gas protection. Nitrogen is a kind of inert gas, rich in air source, and its air content is 79%. Applications in production have become increasingly widespread.
At present, Jiangsu Jiayu PSA Nitrogen Generator is widely used in safety protection gas, displacement gas, nitrogen injection tertiary oil recovery, coal mine fire prevention and fire extinguishing, nitrogen-based atmosphere heat treatment, anti-corrosion and explosion-proof, electronic industry, and integrated circuits. In the field of nitrogen production, carbon molecular sieves and zeolite molecular sieves are used more often. The separation of oxygen and nitrogen by molecular sieves is mainly based on the difference in the diffusion rate of these two gases on the molecular sieve surface. Carbon molecular sieves are carbon-based adsorbents that combine the characteristics of activated carbon and molecular sieves. The carbon molecular sieve consists of tiny pores. The smaller diameter gas diffuses faster and enters the solid phase of the zeolite more. In this way, nitrogen can be enriched in the gas phase.
Jiayu pressure swing adsorption nitrogen generator (referred to as PSA nitrogen generator), using PSA special molecular sieve as adsorbent material, according to the pressure swing adsorption principle to produce nitrogen equipment. Under normal temperature and low pressure conditions, using the difference in the size of the molecular diameters of oxygen and nitrogen, the difference in the amount of adsorption and the adsorption rate formed in the molecular sieve phase, calculate the timing of its work through a computer to obtain high-purity nitrogen.
The cylinder of PSA nitrogen generator consists of a cylinder barrel, a piston, a transmission rod, a guide rod, and an alarm device, and has the following advantages:
1. The pressing force F = PS is related to the adsorption pressure and the piston area of ??the cylinder. It has nothing to do with other factors. In the process of pressure swing adsorption, the adsorption pressure is constant, the piston area is fixed after it is manufactured. Therefore, the pressing force of the cylinder pressing does not change with the stroke.
2. The stroke of the cylinder can be measured or sensed outside, and the alarm point can be set in advance.
3. The gas required by the cylinder is taken directly from the adsorption tower and can be synchronized with the adsorption tower at any time.
In some emerging materials industries, electronics industry, integrated circuits, beer and beverages, etc. The use of inert gases is also constantly expanding into new applications. For example, the new PSA nitrogen generator has been used for the inert protection of mobile phone lithium battery production, nitrogen packaging for beer and beverages, etc. Dehydration and drying of nitrogen in silicone production, snack food replaces air and deoxidizer for nitrogen encapsulation. The application of nitrogen makes the products of these companies in the process technology, product quality, and has won competitiveness.
