Product Description

Company introduction

 

LDH series liquid nitrogen equipment is based on the pressure swing adsorption principle, using high-quality carbon molecular sieve as adsorbent, under a certain pressure, from the air to produce nitrogen. After purifying and drying compressed air, pressure adsorption and decompression desorption are carried out in the absorber. Due to the kinetic effect, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much higher than that of nitrogen. When the adsorption is not in equilibrium, nitrogen is enriched in the gas phase to form the finished nitrogen. Then decompression to atmospheric pressure, adsorbent adsorption of oxygen and other impurities, to achieve regeneration. Generally, two adsorption towers are set up in the system. One tower absorbs nitrogen and the other tower is desorption and regeneration. Automatic control by PLC program makes the two towers work alternately. The finished nitrogen is then passed through the refrigerator to produce liquid nitrogen.

Technical features:
1. Adopt diversified environmental protection refrigerating medium with independent intellectual property rights2. The cold box adopts special secondary foaming technology to achieve good thermal insulation effect3. The refrigeration system adopts internationally famous compressor, which is safe and durable, and the spare parts are conventional4. Compared with the traditional Stirling liquid nitrogen unit, it has the following advantages: low cost, no regular maintenance, high reliability and long service cycle.
