Evaporative crystallization treatment device suitable for scaling prevention of high-salinity wastewater

The utility model discloses an evaporative crystallization treatment device suitable for scaling prevention of high-salinity wastewater. The system mainly comprises a high-salinity wastewater materialsystem, a crystallization liquid dehydration system and a steam system, energy consumption can be reduced; the energy consumption of the evaporative crystallization system generally accounts for morethan 50% of that of the whole zero-emission system; evaporation system after scaling, obvious gradual reduction of heat exchange efficiency, most directly, the evaporation capacity is reduced; finally, the system cannot operate at full load. In the initial stage of scaling, the evaporation capacity can be guaranteed by increasing the steam amount or adjusting a compressor, the heat exchange efficiency is further reduced along with increasing of the thickness of a scale layer, the evaporation capacity cannot be guaranteed even if the steam energy consumption is increased, and the energy consumption is reduced by 12% or
