[0027] An air inlet pipe 6 and a liquid discharge pipe 7, the air inlet pipe 6 and the liquid discharge pipe 7 are respectively connected with the jacket 2, and the other ends of the air inlet pipe 6 and the liquid discharge pipe 7 are connected with an external steam generator;

[0028] An air inlet pipe 8, the air inlet pipe 8 is mounted on the top of the distillation kettle 1, and the other end of the air inlet pipe 8 is connected with the external steam generator;

[0029] A liquid discharge pipe 9, the liquid discharge pipe 9 is connected with the air inlet pipe 8, the liquid discharge pipe 9 is located in the distillation kettle 1, and the other end of the liquid discharge pipe 9 penetrates through the distillation kettle 1 and is connected with the external steam generator.

[0030] In actual application, the waste water is introduced into the distillation kettle 1 through the feed pipe 3, and the distillation kettle 1 is in a negative pressure state through the negative pressure assembly 19, so as to reduce the boiling point of the waste water, the primary steam is introduced into the air inlet pipe 6 and the air inlet pipe 8 through the external steam generator, the primary steam in the jacket 2 contacts the surface of the distillation kettle 1, so as to exchange heat with the distillation kettle 1 and the waste water in the distillation kettle 1, the primary steam in the liquid discharge pipe 9 directly exchanges heat with the waste water in the distillation kettle 1, so that the waste water at the center position of the distillation kettle 1 can be heated and evaporated at the same time, the waste water close to the inner wall of the distillation kettle 1 and the waste water at the center position of the distillation kettle 1 are heated at the same time, so as to improve the heating and distillation speed of the waste water, and further improve the distillation efficiency, and meanwhile, the energy loss is reduced;

[0031] The primary steam is liquefied after heat exchange, the liquefied primary steam enters the external steam generator through the liquid discharge pipe 7 and the liquid discharge pipe 9, and the liquefied primary steam is evaporated into new primary steam through the steam generator, so as to recycle the primary steam, on the one hand, the energy loss is reduced, and on the other hand, the liquefied primary steam has a certain temperature, and the primary steam can be quickly formed when the liquefied primary steam is evaporated through the steam generator, so as to improve the efficiency of forming the primary steam, and further improve the distillation efficiency of the waste water.

[0032] Further, the distillation kettle 1 is externally provided with a jacket 10, a liquid storage tank 11 is mounted in the jacket 10, the liquid storage tank 11 stores the waste water, a feed pipe 16 is connected with the liquid storage tank 11, the feed pipe 3 is connected with the liquid storage tank 11, a pump body 14 is mounted on the feed pipe 3, a spiral pipe 13 is connected with the steam discharge pipe 4, the spiral pipe 13 is wound around the liquid storage tank 11, the other end of the spiral pipe 13 is connected with a steam discharge pipe 15, and the other end of the steam discharge pipe 15 is connected with an external steam condenser.

[0033] The jacket two 10 is also provided with a storage tank 12, which is located below the liquid storage tank 11 and is attached to the liquid storage tank 11. The storage tank 12 stores the concentrated liquid produced after evaporation. The unloading pipe one 5 is connected to the storage tank 12.

After being heated, the wastewater can evaporate quickly, reducing the heating time of the wastewater and improving the distillation efficiency of the wastewater.

[0035] The high-temperature secondary steam also heats the storage tank 12. The concentrated liquid produced after evaporation of the wastewater enters the storage tank 12 through the unloading pipe one 5. Since the wastewater is evaporated at low pressure, the temperature of the concentrated liquid produced is not high. At this time, the concentrated liquid is heated to increase its temperature.

[0039] The bent part of the liquid discharge pipe two 9 is provided with a side scraper 93, which is in contact with the inner wall of the distillation kettle 1. The part of the liquid discharge pipe two 9 close to the bottom of the inner cavity of the distillation kettle 1 is provided with a bottom scraper 94, which is in contact with the bottom of the inner cavity of the distillation kettle 1.

[0041] In one case of the embodiment, the driving member 18 can be a motor or other component capable of driving the main gear 181 to rotate.

[0042] In actual application, the driving member 18 is started to drive the main gear 181 to rotate the gear 92, so that the liquid discharge pipe II 9 rotates to agitate the wastewater in the distillation kettle 1, so that the wastewater is uniformly heated to improve the evaporation speed of the wastewater and improve the distillation efficiency; the liquid discharge pipe II 9 can heat the wastewater at the center position of the distillation kettle 1 and agitate the wastewater to uniformly heat the wastewater, so as to improve the evaporation speed of the wastewater;
