Energy-saving and consumption-reducing triple-effect heat cycle evaporation device

The utility model discloses a triple-effect heat cycle evaporation device capable of saving energy and reducing consumption. Heat circulation is realized by arranging a heat circulation structure on a pipeline of the triple-effect evaporation device. A heat source of the first-effect evaporation system is from refrigerant steam, a heat source of the second-effect evaporation system is from secondary steam generated by first-effect evaporation, a heat source of the third-effect evaporation system is from secondary steam generated by second-effect evaporation, and secondary steam generated by third-effect evaporation is absorbed by a refrigerant in the condenser, so that the heat sources are recycled, and energy is saved. 本实用新型公开了一种节能降耗的三效热循环蒸发装置。通过在三效蒸发装置的管路上设置热循环的结构来实现热循环。一效蒸发系统的热源来自于制冷剂蒸汽，二效蒸发系统热源来自于一效蒸发产生的二次蒸汽，三效蒸发系统热源来自于二效蒸发产生的二次蒸汽，三效蒸发产生的二次蒸汽被冷凝器中的制冷剂吸收，以达到热源循环利用，节约能源。
