Description

The direct distilling apparatus of solar energy that deflector is arranged

The utility model belongs to solar energy distillation device.

The direct distilling apparatus of solar energy generally has two kinds of versions, a kind of is filled with water in a tray, the glass plate of an inclination of dish upper cover, when solar radiation adds hot water, the steam and the hang plate of evaporation meet, be condensed into the globule, converge into clear water again and flow down, enter in the fresh water water receiver from oblique glass plate.The latent heat of emitting when this structure is not utilized the steam condensation.

Another kind of form is the latent heat of emitting when utilizing the steam condensation, and the multiple-effect solar still that designs with the Frenchman is representative, and its structure is; The heat absorption flat board that multilayer is had loose structure behind is placed on each layer maintenance certain clearance in the casing of glass cover-plate, makes the irradiation of casing glass surface over against sunlight.Material water or flow into up or from the following back side that is drawn into every layer of porous plate by the capillary principle.Sunlight by the flat glass cover plate the surface heating of first laminate after, the water its porous back side in also is heated and evaporates, steam surperficially contacts with the second layer in the process of rising, condensation, accumulate in the water collector of clear water below the surface flows to.Liberated heat made the water in its porous back side be heated evaporation when second layer surface had absorbed the steam condensation, and steam in the surface condensation of three ply board, accumulates clear water again, and the like.Its shortcoming cryosurface is below steam, the chance of contact is few, condensation number is few, if the gap of each layer is reduced, then the humidity of evaporating surface increases, make the evaporation difficulty, in addition, its heat absorption evaporation plate is plate shaped, is that low pressure is to reduce evaporating temperature if make its inside, raise the efficiency, but its planar structure is difficult to bear the pressure of atmosphere.

The purpose of this utility model provides a kind of ripple absorber plate solar still that guiding gutter is arranged.

The utility model is achieved in that absorber plate is a tubular, and the outside is smooth, the inside porous, and upper limb has the water supply push pipe that cracks inside, on have interface and water supply arm to join.The side section of plate is a ripple type, has outside with peak line to weigh the guiding gutter of bottom of which has holes mutually.The absorber plate multilayer of different-diameter is nested, and interlayer has certain interval and curved surface symmetry, is cucurbit serial type chamber, in the solar vacuum heat-collecting pipe of packing into, seals with lid.The water main is connected with each arm and feed water inlet, the interior unidirectional feed water valve crossed on the lid communicate with water-feed.Guiding gutter bottom has aqueduct to cross the water guide mouth on the lid, outer check valve communicates with the water purification container.Also has an outer check valve that discharges water and exit on the lid.When sunlight raises outer evaporative condenser plate temperature by thermal-collecting tube, make the water of supplying with by feed pipe in its porous back side be heated evaporation, steam rises to the waist in cucurbit string shape chamber, kept off back by guiding gutter, and along the guiding gutter bottom surface, the condensation cavity face of second laminate descends, condense into water droplet and accumulate clear water again and flow to down in the guiding gutter of waist, pass down according to this from the guiding gutter of bottom land orifice flow below following cryosurface enters, after nethermost guiding gutter enters mozzle.The steam that does not condense and enter in the cucurbit serial type chamber, upper strata converges with the steam that evaporates again, carries out above-mentioned circulation in each cavity.Liberated heat had heated the water in its evaporating surface when cryosurface absorbed the steam condensation, evaporated and condensation in the cucurbit serial type chamber between second and third laminate again, and the rest may be inferred up to the inside one deck.Temperature in vacuum tube raises, pressure rises, inside unidirectional feed water valve is closed, export-oriented single-way gas-discharge valve, water purifying valve are opened, the waste water of the not vaporization that not coagulating in the thermal-collecting tube flows down on gas and the spontaneous evaporation plate is through vent valve, enter atmosphere, the distilled water in the mozzle enters water purifier through water purifying valve simultaneously.When the air pressure in the thermal-collecting tube reaches when equating with atmospheric pressure, the position is higher than water in the water-feed of distiller under action of pressure, entering the evaporative condenser plate by feed pipe descends its temperature, air pressure in the thermal-collecting tube drops to thereupon and is lower than atmospheric pressure, this moment outer closed check valve, distiller distills under low pressure.Along with the raising of the temperature in the thermal-collecting tube, distiller enters above working cycles again.

Advantage of the present utility model is: it forces steam to contact in the cocycle of spill cryosurface, also increased the distance of evaporating surface, reduced the vapor concentration of evaporating surface, favourable and evaporation of liquid, it can utilize the evaporation under the low pressure easily, and liberated heat is recycling during as much as possible to the steam condensation, thereby has improved evaporation efficiency widely.
