Crystal system is evaporated in succession in ultrasonic wave scale control scale removal

The utility model discloses a crystal system is evaporated in succession in ultrasonic wave scale control scale removal belongs to the petrochemical trade and contains salt sewage treatment technical field. Should evaporate the crystal system in succession includes: heat exchanger (2), first effect crystallization leg (3), centre effect evaporimeter (5), middle heat exchanger (6), centre effect crystallization leg (7), last evaporimeter (9), the end effect heat exchanger (10) of imitating, last effect crystallization leg (11) and the heat source steam input pipeline (22) of imitating are imitated to salt solution input pipeline (24), head effect evaporimeter (1), head, wherein, the evaporimeter of same effect, heat exchanger and the vertical direction of connection in crystallization leg edge install the ultrasonic emission device respectively together on each shell of imitating the heat exchanger. Should evaporate in succession that crystal system area is little, the energy consumption is low, pipeline in the system is difficult, and scale deposit and jam take place.
