A technical analysis of PSA technology Reed is widely used in chemical, electronics, textile, coal, petroleum, natural gas, pipeline, food, glass, machinery, powder metallurgy, magnetic materials and other industries. For different industries different user requirements for different nitrogen use, Reed provides personalized, PSA nitrogen equipment professional, fully meet the needs of different users of gas nitrogen generator requirements. Our company has the advantages of simple process flow, normal production, high degree of automation, open parking convenient, less wearing parts, convenient maintenance, low production costs and so on. Two, the working principle of RDN series is based on PSA nitrogen making machine The principle of using high quality carbon molecular sieve as adsorbent, under pressure from the air to produce nitrogen. After purification dry compressed air, the pressure in the adsorber adsorption, vacuum desorption. Due to the dynamic effect of oxygen on carbon molecular sieve nitrogen is far greater than the diffusion rate of pores, adsorption is not balance when the concentration of nitrogen in the gas phase is finished. Then, the formation of nitrogen decompression to atmospheric pressure, the adsorption desorption of adsorbed oxygen and other impurities, achieve regeneration. General settings in the system of two adsorption towers, one tower of nitrogen adsorption capacity, the other tower desorption regeneration, automatic control through the PLC program, two towers cycle In order to achieve the purpose of continuous production, high quality nitrogen. Three, technical advantages of RDN series energy-saving nitrogen device the convenient installation and has the advantages of compact structure, integral skid mounted, small area without the need for infrastructure investment, less investment. The high quality carbon molecular sieve has high adsorption capacity, high compressive strength, long service life. The normal operation life is 8 years. The fail safe system for alarm and automatic start function user configuration fault system, to ensure the safe operation of the system. The nitrogen supply is more economic than other PSA process is a simple and convenient method for preparing nitrogen, using air as raw materials, energy consumption is only the consumption of air compressor Electric energy, has low running cost, low energy consumption, high efficiency advantages. The mechanical and electrical integration design automation operation of imported PLC control automatic operation. The purity of nitrogen flow pressure adjustable and continuous display, set pressure, flow rate, purity alarm and remote automatic control and measurement, realizes unattended operation control. Advanced system makes the operation more simple, can realize unattended and remote control, and can be used for real-time monitoring of various working conditions, so as to ensure the gas purity, flow stability. The high quality components is to ensure stable and reliable operation of pneumatic valve, solenoid pilot valve etc. Key parts imported configuration, reliable operation, fast switching speed, service life of up to millions of times, low failure rate, convenient maintenance, low maintenance cost. The continuous display of the oxygen content of the autoalarm online monitoring system to ensure the purity of nitrogen, nitrogen purity and stability. The advanced filling technology to ensure the service life of the equipment used with advanced technology, the molecular sieve distribution uniformity is not dead, and not easy powder; automatic clamping device for multistage gas distribution device and balance the adsorption tower. Carbon molecular sieve adsorption performance and compression state, prolong the service life of the carbon molecular sieve. The unqualified automatic nitrogen Low purity nitrogen automatic emptying emptying system starting early, after reaching the targets. The purity of aspirated ideal range of nitrogen purity convenient, according to the needs of users in 79% ~ 99.99% between the arbitrary regulation, coupled with the unique purification technology in the level series with nitrogen purification, high purity nitrogen can be prepared in 99.9995%. The unique system of cyclic switching process of valve wear is reduced, prolonging the service life of equipment and reduce the maintenance cost.
