目前在表面式海水蒸发器中减小水垢热阻的方法,还不大有效,原因是缺乏有关水垢热物理性质和相成分的统计资料;对水垢的沉淀过程本身的研究也很不够。海水蒸发器中水垢形成是在热液条件下多元系统过饱和溶液结晶的复杂过程。因此,当研究水垢结晶增长的条件时,必须考虑到化学成分、被蒸发的盐溶液的浓度和温度。以往在确定水垢相成分方面所作的研究,大多基于用化学分析法得到的数据。这些研究多属于假想性的,因为这些研究无法考虑海水中所含的大约40种微量元素(其重量百分数在1.10~(-14)％
The current method of reducing the scale thermal resistance in surface seawater evaporators is less effective because of the lack of statistical data on the physical properties and phase composition of scale heat and the lack of research on the scale precipitation process itself. Scale formation in seawater evaporators is a complex process of supersaturated solution crystallization in multivariate systems under hydrothermal conditions. Therefore, when studying the conditions for the growth of scale crystals, the chemical composition, the concentration and the temperature of the brine solution to be evaporated must be taken into account. In the past to determine the scale components of the research done, mostly based on the data obtained by chemical analysis. These studies are mostly hypothetical because these studies can not account for about 40 trace elements contained in seawater (weight percentages are in the range of 1.10 to -14%
