Further, referring to Fig. 1, liquid feed device includes the second liquid reserve tank 22 and the tenth pipeline 23；Second liquid reserve tank 22 Water outlet connection first pipe 3 first end, the first end of the tenth pipeline 23 connects the water inlet of the second liquid reserve tank 22, seawater By the tenth pipeline 23 enter the second liquid reserve tank 22, seawater first in the second liquid reserve tank 22 stand after, then by first pipe 3 into Enter evaporation tank 1, can prevent the solid impurity in seawater from entering the other equipment in system, to influence the work of equipment.

Further, referring to Fig. 1, further including second heat exchanger 24, the first end connection of second heat exchanger 24 the The second end of ten pipelines 23, second end connect the input terminal of condenser 5, for that will enter the heat of the vapor before condenser 5 The seawater being conducted in the tenth pipeline 23 can not only be saved using the heat into the vapor before condenser 5 come pre- hot sea water About energy can also reduce thermal pollution by reducing heat.

Further, referring to Fig. 1, further including the 11st pipeline 25 and secondary heater 26；The of 11st pipeline 25 One end connects the second liquid reserve tank 22, the second end of the 11st pipeline 25 of input terminal of secondary heater 26, output end connection first The first end of pipeline 3.

It is understood that using heat pump techniques, so that the liquid refrigerant of low-temp low-pressure absorbs heat in condenser 5 and gas It is melted into low-pressure steam, low-pressure steam, at the steam of high temperature and pressure, utilizes the high temperature and pressure by the compressor compresses in heat pump system Steam the seawater in the 11st pipeline 25 is heated in secondary heater 26.

Further, Fig. 1 and Fig. 2 are please referred to, solar panel 8 is set to the top of evaporation tank 1, and solar battery The backboard of plate 8 is made of high light transmission material, and the backboard of solar panel 8 is oppositely arranged with the extinction face 27 of evaporation tank 1, the sun The backboard of energy solar panel 8 is made of high light transmission material, and sunlight can be made through solar panel 8, prevent sunlight too Positive to put aside heat on the backboard of solar panel 8, the backboard of solar panel 8 is oppositely arranged with the extinction face 27 of evaporation tank 1, can So that sunlight penetrates the backboard of solar panel 8 and is radiated on evaporation tank 1, to make the heat sink 2 in evaporation tank 1 Wavelength can be absorbed in the sunlight of 1100nm or more.

The above, above embodiments are only to illustrate the technical solution of the application, rather than its limitations；Although referring to before Embodiment is stated the application is described in detail, those skilled in the art should understand that: it still can be to preceding Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these It modifies or replaces, the spirit and scope of each embodiment technical solution of the application that it does not separate the essence of the corresponding technical solution.
