1机械蒸发技术应用的历史机械蒸发技术是将二次蒸汽再压缩做为热源,实现汽化潜热的持续循环利用的蒸发过程。机械蒸发系统被称为MVC蒸发(Mechanical Vapor Compression),或者MVR蒸发(Mechanical Vapor Recompression)。机械蒸发(Mechanical Vaporize Compression,MVC)技术由美国舰船的海水淡化研发,20世纪60年代该技术成功应用于化工、制药等行业,目前世界各国不同行业和领域有上千套系统在运行。在我国,自2006年开始,由于“机械蒸发-离子交换”(简称MVC-DI工艺)技术处理垃圾渗滤液工艺的研发成功,使得蒸发技术得以在渗滤液处理方面成功应用。成功应用的首个工程为潮州市锡岗垃圾卫生填埋场,处理规模为200t/d。2“机械蒸发-离子交换”处理垃圾渗滤液技术“机械蒸发-离子交换”技术工艺流程为:垃圾渗滤 A history of mechanical evaporation technology Mechanical evaporation technology is the secondary steam recompression as a heat source to achieve the latent heat of vaporization of the continuous recycling of the evaporation process. Mechanical evaporation systems are known as Mechanical Vapor Compression, or Mechanical Vapor Recompression. Mechanical Vaporization Compression (MVC) technology was developed by the desalination of American ships. In the 1960s, the technology was successfully applied to the chemical and pharmaceutical industries. Currently, there are thousands of systems running in different industries and fields all over the world. In China, since 2006, the successful development of landfill leachate treatment technology by “mechanical evaporation-ion exchange” (MVC-DI technology) has enabled the successful application of evaporation technology in leachate treatment. The first successful application of the project is Chaozhou City, Jiegang Sanitary Landfill, the scale of 200t / d. 2 “mechanical evaporation - ion exchange ” treatment of landfill leachate technology “mechanical evaporation - ion exchange ” technology process: landfill percolation
