Improved double-effect cross-flow MVR system

The invention discloses an improved double-effect cross-flow MVR system which comprises a feed liquid flow subsystem, a cross-flow steam compression subsystem, a waste heat recovery subsystem and a cleaning system, the feed liquid flow subsystem is connected with the cross-flow steam compression subsystem, and the waste heat recovery subsystem is connected with the cross-flow steam compression subsystem and the cleaning system. The improved double-effect cross-flow MVR system is low in operation energy consumption, the flash evaporation phenomenon cannot be generated during discharging, pipeline blockage can be avoided, and the evaporation efficiency is high. 本发明公开了一种改进型双效错流MVR系统，包括料液流程子系统、错流蒸汽压缩子系统、余热回收子系统及清洗系统，所述料液流程子系统与错流蒸汽压缩子系统连接，所述余热回收子系统分别与错流蒸汽压缩子系统及清洗系统连接。本发明运行能耗低、出料时不会产生闪蒸现象，能够避免管道堵塞，蒸发效率高。
