[0002] The MVR evaporation system is an efficient and energy-saving evaporation technology. It uses a steam compressor to compress the generated secondary steam, increase its temperature and pressure, and then send it back to the evaporator as a heating heat source, thereby realizing the recycling of steam. Vacuum distillation technology, on the other hand, performs distillation operations under reduced pressure conditions, which can lower the boiling point of the solution and improve separation efficiency. Combining MVR technology with vacuum distillation technology can further improve evaporation efficiency and reduce energy consumption. However, in the actual application of the MVR vacuum distillation system, both ends of equipment such as the separator heater need to be fixed with connecting pipes for use.
