After the heat exchange between the stock solution and the refrigerant in the first heat exchange tube 111, the stock solution (wastewater) is warmed to generate a phase change, thereby generating secondary steam, and the refrigerant is condensed into a liquid. The secondary steam enters the separation chamber 12 for gas-liquid separation, and small liquid drops carried away by the secondary steam are separated from the steam by the action of gravity, and the secondary steam is purified by the action of the demisting net 17.

The cooling water is cooled by the first air cooler 32 and continuously enters the exhaust condenser 2 for recycling, and the air in the first cold air space 321 of the first air cooler 32 is changed into hot air. Then, the hot air in the first cold air space 321 of the first air cooler 32 enters the bottom of the spraying space 41, and the concentrated solution at the bottom of the heating chamber 11 is introduced into the upper end of the spraying tower 4 through the concentrate discharge pump 51, so that the concentrated solution is sprayed downwards through the spray header 42 positioned in the spraying space 41, and the hot air and the concentrated solution sprayed by the spray header 42 form convection heating, so that the water in the concentrated solution is evaporated, crystals are obtained, and the treatment effect of zero emission is achieved. .
