Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in Figures 1 and 2, the present utility model proposes a low heat consumption waste liquid distillation device, comprising a tank body 1 and a cover body 2 located on the tank body 1, and the cover body 2 is connected to the tank through a hinge On the body 1, a waste liquid chamber 3 is provided in the tank body 1, a first vacuum chamber 4 is provided outside the waste liquid chamber 3, and a first vacuum chamber 4 is provided between the first vacuum chamber 4 and the tank body 1. Two vacuum chambers 5, the cover body 2 seals the first vacuum chamber 4 and the second vacuum chamber 5; the top of the waste liquid chamber 3 is connected with a condensation pipe 6; the first vacuum chamber 4 and the second vacuum chamber The chambers 5 are respectively connected with vacuum devices 8 . The use method of the device is: pouring waste liquid into the waste liquid chamber 3, and closing the cover 2, a heating device is provided outside the waste liquid chamber 3, and the heating device is energized, and the heating coil of the heating device is heated. 7 is wrapped on the tank body 1, and then the waste liquid inside is heated, and the first vacuum chamber 4 and the second vacuum chamber 5 are evacuated at the same time. The vacuum state of the first vacuum chamber 4 makes the boiling point of the waste liquid become 40 °C, when the heating coil 7 makes the temperature in the waste liquid chamber 3 reach 40 °C, some substances in the waste liquid are vaporized and discharged from the air outlet 13 at the top of the waste liquid chamber 3, and the cover body 2 is provided with air outlet holes 13.
