本发明公开了一种基于诱导结晶法的高倍浓缩蒸馏淡化系统及方法，系统包括蒸发器、冷凝器、母液罐、晶种罐、旋流器、泵、阀等。设备启动时预先通过晶种罐向海水中投加与垢质晶核相同或相近的诱导晶种，使蒸发过程中形成的析晶垢优先附着在诱导晶种表面，从而阻断向换热面沉积，正常运行后通过旋流器、母液罐使一股含有诱晶颗粒的母液回流至强制循环管路，由强制循环泵输送至各效蒸发器充当诱导晶种的作用，无需继续添加诱导晶种。本发明的方法，整个流程无需添加化学阻垢剂，可以彻底消除化学阻垢剂对环境造成附加影响，同时本发明可以实现高倍浓缩，在产水负荷确定的前提下，可以大大降低原料海水取水量，降低系统运行电耗。

 The invention discloses a high-power concentration distillation desalting system and a high-power concentration distillation desalting method based on an induced crystallization method. The system comprises an evaporator, a condenser, a mother liquid tank, a crystal seed tank, a cyclone, a pump, a valve, and others. When the device is started, an induced crystal seed with the same or approximate scale crystal nucleus is fed in seawater through the crystal seed tank; thus the separated crystal scale formed during the evaporation process is preferentially attached on the surface of the induced crystal seed, thus deposition towards a heat exchange face is blocked; after normal running, mother liquid containing induced crystal grain backflows to a compulsory circular pipeline through the cyclone and the mother liquid tank, and conveys to every efficient evaporator by the compulsory circular pipeline to induce crystal seed; the induced crystal is not required to add. According to the method, the whole flow does not need to add chemical scale inhibitor, the additional influence of chemical scale inhibitor on the environment can be completely removed; meanwhile, the high-power concentration distillation desalting system can realize high power concentration, and greatly reduce raw material seawater intake and reduce the running power consumption on the basis of confirmed water load.
