Liquid discharge device of triple-effect evaporator

The utility model relates to the technical field of evaporators, in particular to a triple-effect evaporator drainage device which comprises a main body, a drainage mechanism and a supporting mechanism, the drainage mechanism is installed inside the main body, the supporting mechanism is fixed at the bottom of the main body, the inner side surface of the main body is fixedly connected with a heat exchanger, and the drainage mechanism comprises a drainage channel, a material collecting disc and a drainage plate. The liquid discharging channel is arranged at the bottom of the main body and is communicated with the interior of the main body, the material collecting disc and the drainage plate are fixedly connected to the inner side surface of the main body, and the drainage plate is located below the material collecting disc. By arranging the liquid discharging mechanism, the time of the concentrated liquid in the evaporator can be effectively prolonged, so that the mother liquid can be sufficiently concentrated
