Product Description

1, the device adopts low-pressure reflux expansion process, the system is safe, easy to operate; 2, Used pre-cooling units, thus greatly extended the molecular sieve purifier switching service life. The main unit in the air-cooling unit are assembled by imported parts, with consummated pressure, temperature and other sensors to exclude the saturated water in the air automatically; 3, Used aluminum plate heat exchanger with little temperature difference at the hot-side, so that the distillation fractionating tower is safe, reliable, and longer life; the longitudinal seam of the tower were nondestructive testing inspected to ensure the safe and reliable operation of fractionating tower; 4, Used efficient turbo-expander, which can be continuous long-term stable operation; 5, The main components of the apparatus, electronic control system are the introduction of technology products, quality reliable, use of orifice plate flow meter, transmitter and temperature limited figure meter, counting correctly and reliably; 6, Used zirconium and oxygen analyzer for analysis of high-purity nitrogen, online tracking and display; 7, Only need normal run-time inspection for complete sets of plant and can be restarted after downtime without intermediate heating. 8, The fractionator of the plant uses new unique aluminum structure with the single-tower design. 9, the device is configured with two electric heaters (domestic similar device with only one electric heater), one for purification device, one for maintenance at downtime, non-interfering. 10, If compared with the PSA device with the purification behind, no need for the purification deveice behind, without a variety of consumption of oxygen removal agent. The cost of units cubic meter of nitrogen is lower roughly about 20%.
