[0055] The waste water is boiled and evaporated in the evaporator tube 4, the steam enters the second partition heat exchanger shell 7 to exchange heat with the waste water in the second partition heat exchanger tube 8, the steam is condensed into water, and enters the distilled water storage tank 10 and is automatically discharged from the discharge port 14 when reaching a certain liquid level.
