概述
The SeaWaterDistiller is working on the well-known vacuum distillation principle. Waste heat from the main engine on board is utilized as heating medium for evaporation. The evaporation takes place in the evaporation plate bundle located in the lower part of the housing. A part of the incoming sea water evaporates due to the high vacuum inside the housing. The generated vapor is cleaned from sea water droplets while flowing through a wire mesh demister.
冷凝是在壳体内上部的冷凝器板束中发生。 冷凝器是通过海水冷却。 冷凝产生的潜热被传递给海水。 冷凝/蒸发温度因海水温度而异。 少量加热后的海水被用作蒸发器束的给水。 最大的部分被用作空气/盐水组合喷射器的驱动介质。
该喷射器有双重功能: 将多余的海水(所谓的盐水)和不凝性气体从壳体中抽取出来创建真空。 馏出物质量(盐度)在控制面板上进行监控。 如果盐度超过调整的设置点 (2 – 10 ppm),会通过电磁阀将馏出物返回到蒸发器中。
