Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram of evaporator in the present invention.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Fig. 1 ~ Fig. 2, a kind of compact type desalination plant, mainly by blower 1, evaporator 2, heating plate 3,
Condenser 4, spiral coil cooling tube 5, fresh water collecting case 6, cooler bin 7, concentrated seawater case 8, cooling pump 9, concentrated seawater pump 10 and heat insulation layer
11 compositions.Wherein: 1 air intake vent size of blower can LINEAR CONTINUOUS adjust, different wind speed can be studied to whole system fresh water yield
It influences, 1 air outlet of blower is connect with the wind entrance of evaporator 2；Evaporator 2 is made of resistant material, for example, ceramics, prevent by
Seawater corrosion, evaporator 2 include wind entrance, wet-hot steam outlet, Mare Frigoris water inlet and hot sea water outlet, apoplexy entrance and wind
Machine 1 connects, and wet-hot steam outlet is connect with condenser 4, and Mare Frigoris water inlet is connect by concentrated seawater pump 10 with concentrated seawater case 8, heat
Seawer outlet is directly connect with concentrated seawater case 8；The inclination of heating plate 3 is placed in evaporator 2, and heating plate angle can be adjusted as needed
Section, concentrated seawater, which flows through in 3 upper surface of heating plate and generates vapor, to be filled in evaporator 2, the sky that vapor and blower 1 are blown out
Gas is mixed into wet-hot steam；Spiral coil cooling tube 5 is used to the cooling damp and hot air-water mixture for exporting out from 2 wet-hot steam of evaporator
And obtain cooling down light water and air, 5 import of spiral coil cooling tube is connect by cooling pump 9 with cooler bin 7, and spiral coil cooling tube 5 exports
It is connect with concentrated seawater case 8；Fresh water collecting case 6 is connected to immediately below condenser 4, and wet-hot steam is after spiral coil cooling tube 5 is cooling
