Solar energy collector is the heat collector of solar water heater, with it liquid is carried out preheating.The elevated tank surface is heat insulation with the thick polystyrene foam of 50mm, plays the effect of storage and regulating pondage.Evaporator tower is linked to each other by blower fan with the condensing tower upper end, and concentrated seawater is collected in the evaporator tower bottom.When hot sea water is sprayed to evaporating on the filler by the spray dish, inside and outside the evaporation filler, produce a certain amount of water vapour of water, water vapor is driven by aerofoil fan and is transferred in the condensing tower, obtains fresh water through the cooling of deflector type prolong, and fresh water is collected in the condensing tower bottom or is disposed in the fresh water catch tray.The concentrated seawater that is not evaporated is returned in the solar energy collector again through brinepump.Evaporator tower and condensing tower bottom have ventage, and steam repeatedly circulates in evaporator tower and condensing tower, until being condensed into fresh water.
Adopt the baffling prolong in condensing tower, so not only the contact area of steam and prolong obtains increasing, and plays the effect of shunting with diffusion to driving the water vapor that is transferred to condensing tower through blower fan.Water vapor speed of circulation between condensing tower and evaporator tower can be determined by regulating rotation speed of fan.
Heat-eliminating medium in the deflector type prolong is a seawater, and the water coolant of coming to the suction of seawater well through the water pump deflector type prolong of flowing through from bottom to top is disposed to the seawater well at last.
According to above-mentioned utility model design, the utility model adopts subordinate's technical scheme:
A kind of solar energy sea water desalination apparatus of internal recycle multiple-effect evaporation condensation, comprise solar energy collector, evaporator tower and condensing tower, described evaporator tower and condensing tower place in the integrated housing, and both epicoeles are communicated with by a blower fan, and cavity of resorption is communicated with by a ventage; A high-order hot water storage tank is arranged, and the import and export of described solar energy collector are communicated with the upper and lower cavity of high-order hot water storage tank respectively; A brinepump import is communicated with the cavity of resorption of evaporator tower, and outlet is connected the solar energy collector import respectively by valve and high-order hot water storage tank epicoele.
A spray dish is equipped with in above-mentioned evaporator tower inner chamber middle and upper part, and the outlet of solar energy collector is connected in its import, and connects high-order hot water storage tank epicoele by a valve; The evaporation filler is filled at evaporator tower inner chamber middle part.
The deflector type prolong is housed in the above-mentioned condensing tower, and the feed-water end of deflector type prolong is connected a seawater pump outlet by a valve, and a seawater well is connected in the import of this sea-water pump, and the seawater well is connected in the water side of deflector type prolong; The fresh water catch tray is connected in the condensing tower bottom.
The outlet that solar energy collector is connected by a valve in the top of above-mentioned high-order hot water storage tank, and the import of solar energy collector is directly connected in the bottom, described seawater pump outlet is connected the top of high-order hot water storage tank through a valve.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: the utility model adopts internal recycle to carry out evaporative condenser, has vapor transmission efficient height, water vapor utilising efficiency height, simple to operate, cost is low, and the unit scale adjustable size can be utilized advantages such as low grade heat energy such as sun power.
Description of drawings:
Accompanying drawing is the structure principle chart of an embodiment of the utility model.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further described: referring to accompanying drawing, the solar energy sea water desalination apparatus of this internal recycle multiple-effect evaporation condensation comprises solar energy collector 2, high-order hot water storage tank 5, spray dish 9, evaporator tower 8, evaporation filler 20, blower fan 10, condensing tower 12, deflector type prolong 13, integrated Stainless Steel Shell 11, fresh water catch tray 22, compositions such as brinepump 21, fresh water pump 15.
