Electron tubes type solar energy collector in the utility model can be provided with and patrol a day mechanism, to obtain more energy.
The beneficial effects of the utility model are, adopt wind energy to mend electricity, and full-automation overcomes the under-supply situation of cloudy sun power; Adopt horizontal tube falling film evaporation, be not subjected to external interference, good stability, compact construction, the reliability height, volume is little, and dismantled and assembled maintenance and cleaning can extensively be promoted to island population crowd and coastland small-scale crowd; Device adopts the bed filtration measure, and low to water quality requirement, to seawater, brackish water can both be desalinated; The indoor air of sea water desaltination is forced to convection current, has improved thermo-efficiency greatly, and the caloic loss is avoided in sealing; Man-machine interaction, full automatic control, simple in structure, less investment can be utilized various industrial exhaust heats, has good prospect.
Description of drawings.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment.
Below in conjunction with accompanying drawing the utility model is further described.
A kind of full automatic solar sea water desalinating plant, comprise electron tubes type solar energy collector 1, hot well tank 2, water pump 3, reducing valve 4, sea water by distillation device 5, transverse tube type interchanger 6, seawater groove 7, water-ring vacuum pump 8, fresh water jar 9, strong brine jar 10, water intake mechanism 11, patrol day mechanism 12, settling tank 14 and wind power generation plant 13 are formed, electron tubes type solar energy collector 1 water outlet is connected with transverse tube type interchanger 6 water-ins in the sea water by distillation device 5 through water pump 3, electron tubes type solar energy collector 1 another water outlet is connected through the water-in of reducing valve 4 with sea water by distillation device 5, transverse tube type interchanger 5 water outlets are connected with electron tubes type solar energy collector 1 water-in, sea water by distillation device 5 water-ins with through water-ring vacuum pump 8, fresh water jar 9 one tunnel is connected with settling tank 14 with water intake mechanism 11, another road is connected with strong brine jar 10, strong brine jar 10 one tunnel is connected with sea water by distillation device 5, another road and 1 connection mutually of electron tubes type solar energy collector, wind power generation plant 13 is a water pump 3, water-ring vacuum pump 8 power supplies, patrol 12 power supplies of day mechanism, electron tubes type solar energy collector 1 in the utility model can be provided with and patrol day mechanism 12, to obtain more energy, the structure and the mode of connection of above-mentioned each integral part are same as the prior art, this does not give unnecessary details
Working process of the present utility model is, after carrying out preheating through fresh water jar and strong brine, the seawater of seawater groove enters the electron tubes type solar energy collector, after in heat collector, drawing solar heat, become the top that hot sea water accumulates in water tank, the hot sea water that water temperature is the highest subsequently enters in the sea water evaporator through reducing valve, spray is born falling film evaporation on the transverse tube type interchanger, most of hot sea water is under the effect of water circulating pump in the hot well tank, pipe internal recycle at the transverse tube type interchanger flows, be the evaporation of seawater heat supply, just constantly boiling evaporation, do not evaporate seawater at base of evaporator, enter at last in the strong brine jar, the water vapour that evaporation produces is sucked by water-ring vacuum pump, made it be condensed into water by the cooling of the water ring in it, and together drained in the dense water pot, the water in the dense water pot is because of having absorbed the latent heat of condensation of water vapour, and temperature raises, heat exchanger is set therein, absorbs its waste heat and come pre-hot sea water; Sea water evaporator is kept higher vacuum under the water ring vacuum pump effect, make it explosive evaporatoin under lower temperature, for making strong brine under negative pressure, be discharged in the normal pressure brine tank, adopt the intermittent drainage mode, whole device has only moving equipment vacuum pump and water circulating pump, and energy is supplied with by wind electricity generating system, when the wind foot, wind energy converts in the bag and can store in battery, start when sun power is not enough with micro-chip control, the supply heat, solar energy equipment adopts solar energy sun-seeking mechanism in addition, absorbs sun power in order to maximum efficiency.This device directly enters solar thermal collection system at seawater and the etching problem and the valve tube scale problems that cause, designed the glass tube with vacuum horizontal positioned, nanometer PPR material coating with seawater corrosion resistance, whole seawater desalination system all scribble anti-corrosion, scale-inhibiting coating (chemical scale-inhibiting agent); More and more higher for preventing concentration of seawater in addition, so it is design has water escape valve, regularly intermittent with its discharge.
The beneficial effects of the utility model are, adopt wind energy to mend electricity, and full-automation overcomes the under-supply situation of cloudy solar energy; Adopt horizontal tube falling film evaporation, be not subjected to external interference, good stability, compact conformation, the reliability height, volume is little, and dismantled and assembled maintenance and cleaning can extensively be promoted to island population crowd and coastal area small-scale crowd; Device adopts the multiple filtration measure, and low to water quality requirement, to seawater, bitter can both be desalinated; The indoor air of desalinization is forced to convection current, has greatly improved the thermal efficiency, and the caloic loss is avoided in sealing; Man-machine interaction, Automatic Control, simple in structure, small investment can be utilized various industrial exhaust heats, has good prospect.
