Abstract
Composition of the scaling in the low temperature multi-effect distillation seawater desalination evaporator of a company was analyzed, which revealed that scaling on the outer wall of the heat exchange tube at the first 7 effects was mainly calcium sulfate, in-cluding some calcium carbonate, while scaling on the inner wall of the heat exchange tube at the last effect period are mainly calcium sulfate. The cause of the scaling was also analyzed. Different cleaning programs were drawn up according to different scaling composition. Acid and neutral cleaning process was used for the first 7 effects and acid cleaning for the last effect. Analysis of corrosion test piece after cleaning showed the results were better than na-tional standard. The production of a single set of seawater desalination has increased by 10%.关键词
