降膜式蒸发器真空系统的改进

A motificadion to the vacuum system of falling film evaporator

把水力喷射器与多级泵合用的抽真空系统改为盘管式冷凝器与水环真空泵合用的抽真空系统。经过应用证明 :能耗低 ,冷却水不受污染 ,设备工作稳定效果好。

Practical application proves that the modified vacuum sysytem of falling film evaporater lowered power consumption,made the whole equipment more stable with cooling water free from contaminants.The alternation was done by changing the vacuum system from a sharing of sprayer and multi-grade pump to the sharing of coil-pipe condenser and water-ring vacuum pump.
