摘  要
伴随着现代工业的急速发展，我国已经开始面对巨大的能源危机，能源问题已经成为了如今社会的关注焦点，节能环保也被作为了我国的基本国策之一。MVR技术是针对蒸发过程中产生的二次蒸汽的再利用，充分利用了二次蒸汽的潜热，做到了高效的节能效果。所以MVR技术也得到了国家的大力支持。
本设计主要是对蒸发量为500kg/h的MVR系统的设计，通过计算出MVR系统的换热面积、换热管数目、蒸发罐的尺寸等，同时对蒸汽压缩机、气液分离器、泵的选型。最后在对MVR蒸发器与传统的三效蒸发器针对节能效果进行比较，MVR蒸发器要比传统的三效蒸发器节能50％，达到了节能减排的初始目的，同时也展现出了MVR系统优秀的节能效果。

Research and Development of Mechanical Vapor Recompression System with Evaporation Capacity of 500kg/h
Abstract
With the rapid development of modern industry, China has begun to face a huge energy crisis, energy issues have become the focus of attention in today's society, energy conservation and environmental protection has also been regarded as one of China's basic national policy. MVR technology is for the reuse of secondary steam generated during the evaporation process, making full use of the latent heat of the secondary steam and achieving efficient energy-saving effects. Therefore, MVR technology has also received strong support from the country. [版权所有：http://DOC163.com]
This design is mainly for the design of an MVR system with an evaporation capacity of 500 kg/h. The heat exchange area, the number of heat exchange tubes, the size of the evaporation tank, etc. of the MVR system are calculated. At the same time, the steam compressor, gas-liquid separator, and pump The selection. Finally, in comparison with the energy-saving effect of the MVR evaporator and the traditional three-effect evaporator, the MVR evaporator can save 50% energy compared with the traditional three-effect evaporator, achieving the initial purpose of energy saving and emission reduction, and also demonstrating the MVR system. Excellent energy-saving effect.
