摘要

通过实验研究了不同形式的滤网在液体真空冷却过程中降低失水的效果。实验中采用圆柱形容器并控制液面高度为定值，通过改变片状滤网在容器中的位置来研究失水情况；同时研究了能够阻挡容器侧壁气泡的柱状滤网及综合状滤网对失水的影响；为便于有效比较失水量，提出过压度、实际失水率及失水效率等概念。实验结果表明：将片状滤网置于失水终了的液面处，其降低失水的效果最好；柱状及综合状滤网与片状滤网相比，能够进一步降低失水量。

Abstract

The effect of different forms of strainer on reducing water loss during liquid vacuum cooling process was studied. Using cylindrical containers and keeping the liquid height at a fixed value in the experiments

the situation of the water lose was studied by changing the position of the flaky strainer. The influence for water loss of the columnar and comprehensive-shaped strainers which can resist bubbles from the sidewall was also studied. To compare the water loss effectively

the concepts of overpressure degree

actual water lose rate and water lose efficiency were put forward. The experimental results show that when flaky strainer is located at the liquid surface at the end of the losing water process

the effect of decreasing water loss is the best

and the columnar and comprehensive-shaped strainers can further reduce the water loss compared with the flaky strainer.
