蒸馏法蒸馏法evaporation method zhengliufa蒸馏法(e,aporation method)使海水受热沸腾产生蒸汽,然后冷凝为淡水,是最早采用的热过程海水淡化技术。蒸馏法优点是技术成熟,适用范围广,产水水质好,可利用低位热能和易大型化等。缺点是对中低盐度的水蒸馏能耗高,防腐和防垢要求严等。蒸馏法最常用的是多级闪蒸、多效蒸发和压汽蒸馏等几种类型。 多级闪蒸(MsF)其原理是海水加热到一定温度后(一般90~120℃)被逐级(可多达30~4O级)引人压力依次降低的各闪蒸室,使之在其中迅速地部分汽化,汽化部分冷凝为淡水。多级闪蒸的特点是热能利用率高,造水比高(可达13~14),结垢不严重,易大型化等。目前世界上近60%的淡化水是由多级闪蒸生产的。其单套装置容量最大已达36姗米“/日,最大的多级闪蒸淡化厂为392 400米“/日。 多效蒸发(MED)它是由多个单效蒸发串联组成的系统,前一蒸发器产生的二次蒸汽作为下一蒸发器的加热蒸汽,并冷凝为蒸馏水,如此依次进行至最后一效。多效蒸发有浸没式、竖管式和横管降膜式等几种。其优点是热能可重复利用,造水比随效数增加而增加(可达8~16效),可采用低温蒸发(第一效为55~75℃)等。多效蒸发单机装置规模多在2仪K)~10(肋米,/日,最大单级装置已达20仪刃米3/日。翩悬巨淡婆些鉴生翌兰星全呈兰鉴二日具=点“” 多级闪急蒸馏法示意图 压汽蒸馏(VC)其工作原理是将蒸发的蒸汽压缩,提高其热烩,再返回作为加热蒸汽,之后冷凝为产品蒸馏水。按压缩方式分为机械压缩式和热力压缩式。压汽蒸馏设备简单紧凑,不需冷却水。机械压缩式只用电能等,但结垢严重,设备操作维护要求高。压汽蒸馏装置多为中小型。 在蒸馏过程中,传热面上结垢,影响传热,阻塞管道,使其效率和生产能力下降,所以防垢是蒸馏法的关键问题之一。锅垢有碱性垢和硫酸钙垢之分,碱性垢通过进料海水加酸和添加阻垢剂来控制,硫酸钙垢是借控制最高蒸发温度和盐水浓度来防治。 防腐是解决材料在高温高湿的海水环境下的稳定性问题。从材料上,传热管可选用Cu一Ni合金、铝黄铜、钦管、改性铝管和不锈钢管等;从工艺上,对海水除氧(<10微克/升),保持中性,控制流速和定时清洗等。(高从楷)
