分析 6 0 0 0m3 /h空分设备原氮水预冷系统存在的问题及原因 ,将水循环由原制氧站大循环改为氮水预冷系统内部的自循环 ,只增加水换热器和蓄水器 ,效果明显。
The existing problems and reasons of original nitrogen water precooling system of 6 0 0m3 / h air separation plant were analyzed. The water cycle was changed from the main cycle of the original oxygen station to the internal circulation of nitrogen water precooling system, only the water heat exchanger and Reservoir, the effect is obvious.
