Condensing method for ice crystal of refrigerating and desalting sea water
专利汇可以提供Condensing method for ice crystal of refrigerating and desalting sea water专利检索，专利查询，专利分析的服务。并且PURPOSE: To produce plain water at a high yield while obtaining the plain water of high purity with a small amount of washing water by washing ice crystals, obtained from sea water, with produced plain water and then by concentrating ice crystals by dehydrating the ice crystals.
CONSTITUTION: Ice crystals 1 crystallized in a crystallization tank by refrigeration desalting and covered with brine liquid film 2 are washed with produced plain water and this washing is stopped right before brine liquid film 2 is completely substituted, namely, when brine liquid film 2 is diluted with the plain water to a certain degree. Next, this diluted water is removed by dehydration to concentrate ice crystals. As a method of dehydration and concentration, a filter press type dehydrator is preferable and using a raising filter having many fine fibers stacked on the surface of the filter material as the filter material improves the efficiency of dehydration excellently.
