1. 锅炉补给水系统概述
SUMMARIZE OF BOILER MAKE-UP WATER SYSTEM
在发电厂的蒸汽动力设备中，水是传递能量的物质。在锅炉中，水被加热成蒸汽，经汽轮机作功后，冷凝成水后又返回锅炉。在这一循环过程中，有相当数量水损失掉，需要随时向锅炉补充合格水，以保持水汽系统的平衡，这种补充水叫锅炉补给水。本项目设计锅炉补给水系统，其流程为：
原水®海水淡化系统®除盐系统®除盐水箱

2.2 设计说明
DESIGN INSTRUCTION
本除盐系统采用离子交换技术。该技术使交换剂和水溶液中可交换离子之间发生等物质量规则的可逆性交换，改善水质，而离子交换剂的结构并不发生本质性变化的水处理方式。
The demineralization system uses ion exchange technology. This technology allows exchange agent and aqueous solution to exchange ions occurs between the same quantity of content such as reversible exchange rules，improves water quality, and ion exchange agent structure dosn’t occur essential change in the water treatment.
具体来说，水中各种无机盐类电离生成的阳、阴离子，经过氢型离子交换剂层时，水中的阳离子被氢离子所取代，经过氢氧型离子交换剂层时，水中的阴离子被氢氧根离子所取代，进入水中的氢离子与氢氧根离子生成水（H2O）。或者在经过混合离子交换层时，阳、阴离子几乎同时被氢离子和氢氧根离子所取代生成水分子，从而取得去除水中无机盐的效果。
Specifically, kingds of inorganic salts in water ionize & generate cation and anion, when water crosses hydrogen type ion-exchange agent layer, the cation in water is replaced by hydrogen ions, when water crosses oxyhydrogen type ion-exchange agent layer, the anion is reslaced by hydroxyl ions, hydrogen ions & hydroxyl ions in water produce water(H2O), or when water crosses mixed ion exchange layer, cation & anion almost simultaneously is replaced by hydrogen ions and hydroxyl ions to generate water molecules, to achieve the effect of removing water inorganic salts.
