[description of drawings]
Fig. 1 direet-heating type solar energy sea water desalination apparatus synoptic diagram.
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
[embodiment]
The utility model embodiment as shown in drawings.
The direet-heating type solar energy sea water desalination apparatus is by the seawater extraction element, solar vacuum-tube water heater 1, hot well tank 2, flashing chamber 3, vaporizer-condenser 4, vacuum pump 8, condenser 5, water circulating pump 7, fresh-water tank 6 and the compositions such as pipeline that their are connected.Sand filter 14, sea water preprocessing device 13, water tank 12 and dosing pump 11 etc. that the seawater extraction element is connected successively by pipeline are formed, and connecting pipeline as interchanger before entering the storage hot well tank from condenser 5 and condensation go out outside the fresh water pipe to pass through.Seawater is introduced into condenser during water intaking, and a part flows back to the sea, and another part absorbs waste heats at different levels through interchanger, enters solar energy hot water tank 2 bottoms.
Deliver in the solar energy collector 1 by water pump then; Through the seawater of solar heating to 65-70 ℃ enter the hot well tank upper strata, squeeze into flashing chamber 3 through recycle pump.
The steam of flash distillation is connected to the tube side of vaporizer-condenser by the road in the flashing chamber 3 from the vapour outlet A on top, thermal source as multi-effect distilling, and flashing chamber bottom be provided with one with store the not vaporization seawater water return outlet B that hot well tank is connected, and seawater of not vaporizing drops to the outlet C of the shell side of vaporizer-condenser 4.
Vaporizer-condenser of the present utility model can be set to an effect as required or imitate the multiple-effect evaporation condensation device that is in series and is connected with one.Tube side in the vaporizer-condenser 4 is a heat transfer tube, process in the seawater of heat transfer tube from the vaporizer-condenser shell side, and the fresh water in the pipe behind the vapor condensation enters into the fresh water jar by the road; Part seawater in the said vaporizer-condenser shell side is vaporized and becomes steam, vapour outlet D by vaporizer-condenser top enters next effect vaporizer-condenser as next effect distillatory thermal source via pipeline, or enter condenser, the seawater of not vaporizing is imitated vaporizer-condenser by outlet E to next and is continued heat exchange, or is stored into concentrated seawater jar 10.
Principle of the present utility model is: seawater directly enters the solar vacuum-tube water heater heating, after solar energy collector carries out the collection of sun power, the hot water that seawater is heated into 65-70 ℃ enters cyclic water tank, hot sea water after the preheating enters flashing chamber and carries out flash distillation then, because the pressure-controlling in the flashing chamber is being lower than under the pairing saturated vapour pressure of hot salt brine temperature, so hot sea water enters behind the flashing chamber partial gasification rapidly, the steam that obtains enters in the tubulation pipe of vaporizer-condenser imitating thermal source as low temperature, and the seawater of vaporization and additional seawater did not from top to bottom spray on tubulation just now, steam forms liquid fresh water at in-tube condensation and collects, and the latent heat of vaporization that condensation is emitted is managed outer seawater and is absorbed and become water vapour and as the thermal source of next stage, below is all undertaken by the low-temperature multi-effect mode.Steam enters the next stage vaporizer-condenser and continues desalination, and the like.There are several vaporizer-condensers just to be called several effects, can select the different numbers of imitating according to practical situation.The final section of this device is a condenser, and here the refrigerated sea water that is provided by the external world vapor condensation that the end imitate to be produced becomes fresh water, and the fresh water that goes out with former effect condensations is collected in the lump.The remaining concentrated seawater of not vaporizing in imitate at the end is discharged from its vaporizer-condenser, enter into the concentrated seawater jar, the latent heat of vaporization that vapor condensation is emitted in condenser passes to refrigerated sea water, these seawater parts flow into each multiple-effect evaporation condensation device seawater as a supplement, and another part is got back to cyclic water tank or is discharged into marine greatly.
