Abstract

一种淡化海水的方法，以滤水井过滤的海水为介质，用防腐水泵将其先送入太阳能加热池升温，再经过滤管二次过滤后送入蒸馏塔进行低压蒸馏，同时凭借蒸馏塔外部设置风机经抽气管与蒸馏塔顶部相通，使其产生负压，使塔中的海水在低压下升腾蒸发大量水蒸气，被风机连续抽出，被抽出加压的水蒸气经管道再返回加热池冷却板进行冷却，沿加热池冷却管逆海水进入方向从淡水出水口流出，汇集在淡水池中，蒸馏塔下部设有与料斗配合的绞龙出盐装置，将盐浆输出蒸馏塔外凉干处理。本发明的有益效果：成本极低，易于普及推广。

Description

淡化海水的方法
技术领域
本发明涉及一种淡化海水的方法。
背景技术
目前，淡水生产成本费高，工农业用水及民用水难以承受。海水蒸馏需要的热量是发电厂汽轮机排出的水，存在资源浪费。
发明内容
本发明的目的在于克服上述的不足，提供一种淡化海水的方法。
本发明的技术方案是：一种淡化海水的方法，其特征在于：以滤水井过滤的海水为介质，用防腐水泵将其先送入太阳能加热池升温，再经过滤管二次过滤后送入蒸馏塔进行低压蒸馏，同时凭借蒸馏塔外部设置风机经抽气管与蒸馏塔顶部相通，使其产生负压，使塔中的海水在低压下升腾蒸发大量水蒸气，被风机连续抽出，被抽出加压的水蒸气经管道再返回加热池冷却板进行冷却，沿加热池冷却管逆海水进入方向从淡水出水口流出，汇集在淡水池中，蒸馏塔下部设有与料斗配合的绞龙出盐装置，将盐浆输出蒸馏塔外凉干处理。
本发明的有益效果：成本极低，易于普及推广。
具体实施方式
实施例：一种淡化海水的方法，以滤水井过滤的海水为介质，用防腐水泵将其先送入太阳能加热池升温，再经过滤管二次过滤后送入蒸馏塔进行低压蒸馏，同时凭借蒸馏塔外部设置风机经抽气管与蒸馏塔顶部相通，使其产生负压，使塔中的海水在低压下升腾蒸发大量水蒸气，被风机连续抽出，被抽出加压的水蒸气经管道再返回加热池冷却板进行冷却，沿加热池冷却管逆海水进入方向从淡水出水口流出，汇集在淡水池中，蒸馏塔下部设有与料斗配合的绞龙出盐装置，将盐浆输出蒸馏塔外凉干处理。
