Fig. 1 is the structural principle synoptic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the utility model comprises heat pipe type solar heat collection pipe 1, gas blower 5, impeller pump 4, shower nozzle 6, ball float 3, induced draft fan 12, seawater storage tank 9, fresh water storage tank 8, coil heat exchanger 10, protruded packing and three evaporating pans 7; The condensation end of heat pipe type solar heat collection pipe 1 is inserted near the bottom of device, and the wall of bottom device is provided with the ball float 3 of control liquid level.Have air outlet on ball float 3 tops, the opposite wall, air outlet communicates with the air outlet of gas blower 5.Top apart from air outlet one segment distance is provided with the first step, the second stage and third stage evaporating pan 7, and the bottom of the first step, the second stage and third stage evaporating pan 7 is provided with seawater shower nozzle 6; The top of device is provided with induced draft fan 12, and the outlet of induced draft fan 12 links to each other with the inlet of coil heat exchanger 10, and coil heat exchanger 10 is placed in the seawater storage tank 9, and the outlet of coil heat exchanger 10 imports in the fresh water storage tank 8.The water-in of impeller pump 4 is arranged on the bottom of device, and water outlet is arranged on the top of third stage evaporating pan.Storage tank is provided with seawater outlet 11, seawater is injected into the bottom of device through pipeline.
