Description
Technical field
The present invention relates to a kind of seawater desalination system, in particular to a kind of reflection heat-aggregation and the compound core pattern of Fresnel optically focused
The system of solar seawater desalination, belongs to solar energy heat utilization field.
Background technique
Water area coverage is up to up to 70.8% on the earth, but wherein contains a large amount of mineral in 97% or more water resource
Matter, salinity are up to 30000-4500ppm, directly cannot drink or irrigate, in remaining 3% freshwater resources, 3/4 be
In frigid zone or the glacier of earth two-stage, shortage of fresh water becomes a global problem.
Modern so far from 20th century 60, the technology of sea water desalination is quickly grown, and the mode of the maturation such as way of distillation is big
Scale is applied to industrial production, and China's sea water desalination at present mainly has thermal method and two kinds of embrane method, and it is more that thermal method can be divided into low temperature
The effect way of distillation (LT-MED) and multistage flash vaporization (MSF), embrane method mainly have hyperfiltration (RO) and electroosmose process (ED).Wherein too
Positive energy technology mainly includes two kinds in the Land use systems of field of seawater desalination: first is that solar radiant energy is converted directly into electric energy
Photovoltaic power generation technology；Second is that the photothermal technique using thermal energy is converted solar energy into, mainly including solar thermal collector and too
Yang Chi.
Fresnel Lenses (Fresnell lens), also known as be Fresnel lens, it is made mostly of polyolefine material, glass etc..
Sunray can be gathered to formation focus at one, principle is similar to traditional convex lens.It is compared to convex lens, Fresnel
Each " sawtooth " of lens is equivalent to a convex lens, can eliminate the defect that convex lens corner is dark, fuzzy.
Reflecting mirror has many advantages, such as at low cost, simple process, the sunlight incident light that will have dispersibility using reflecting mirror
It converges on small area collecting plate and improves the radiation energy of unit area heat collector panel, it is this using reflection or refracting optical system
The technology of system is known as heat build-up.
Sea water desalination needs a large amount of energy to come the operation of driving device, the consumption of conventional energy resource and the pollution of environment,
Therefore new energy technology and the binding of sea water desalination industry are current hot spots.The present invention converges solar energy using reflecting mirror
It is combined with Fresnel optical collector convergence sunlight, Fresnel optical collector is not used only and assembles sunlight, reflects simultaneously
Concentrator section can be irradiated to the sunlight secondary reflection of wall surface to receiver by mirror.
Summary of the invention
The purpose of the present invention is to provide a kind of reflection heat-aggregation core pattern solar energy sea water compound with luxuriant and rich with fragrance alunite lens light gathering is light
The system of change combines the heat build-up of solar energy reflection formula and Fresnel Lenses formula optically focused, not only section can the about energy, but also more can
Enough realize makes full use of sunlight, makes up function using light loss.
The present invention is achieved through the following technical solutions: a kind of reflection heat-aggregation and the compound core pattern sun of Fresnel optically focused
Can seawater desalination system, mainly include spilling water nozzle, the frid that is filled with water, distilled water outlet, Fresnel Lenses, reflecting mirror, water-absorbing core,
High transparent glass cover board, water inlet pipe mouth, valve, water tank, distilled water receiving flask, spilling water collecting box, strong brine rinse mouth and necessity
Connecting pipe, by Fresnel Lenses optically focused, reflecting mirror heat build-up two ways complementation carrys out realization device stability and high efficiency distillation sea
Water, to desalinize seawater.
The reflection heat-aggregation and the compound core pattern solar energy sea water desalination apparatus of Fresnel optically focused, are obtained by theoretical calculation model
Out, due south, which is placed, to irradiate in utmostly receiving sunray in one day.
The chassis of the reflection heat-aggregation and the compound core pattern solar energy sea water desalination apparatus of Fresnel optically focused uses tilting, phase
Landing for traditional rectangle distiller, area is smaller, and effective collector area is bigger, and distribution of the seawater in space is heated more
It is even, improve its effective disengagement area.
The reflection heat-aggregation and the compound core pattern solar energy sea water desalination apparatus of Fresnel optically focused are tried to get to the heart of a matter using core configuration,
It tries to get to the heart of a matter and increases core material, seawater is adsorbed on core through capillary action, form water membrane, the low unit bodies of seawater
Long-pending porosity is point of penetration from disengagement area of the seawater in evaporator is improved, to improve the yield of distiller fresh water.
The Fresnel optical collector can be by the sunlight of large area because Fresnel Lenses has stronger spotlight effect
Line is gathered on small area (or even a point), by using Fresnel optical collector, the solar radiation quantity enhancing that distiller absorbs,
Distillation efficiency significantly improves.
The reflecting mirror is mounted on cavity inner wall.When core pattern solar energy sea water desalination apparatus due south is placed, top phenanthrene alunite
Your lens, which receive sunlight, uniformly to be assembled to core material surface, and another part is escaped through Fresnel Lenses, glass cover-plate
It is irradiated to device side wall, reflecting mirror receives the sunlight converged through glass cover-plate escape sunlight with Fresnel Lenses and passes through
Mirror-reflection can increase substantially its surface so that core material receives more sunlights to core material surface
Temperature.
The glass cover-plate top is bonded Fresnel Lenses, and lower part under the action of the steam of portion's evaporation, condenses in the cavity
At distillation droplet, and slide to the frid that is filled with water.
Seawater is housed, and water tank bottom height and seawater pond upper end are horizontal consistent in the water tank, satisfaction is not using
In the case where the complex instruments such as booster pump, water valve, liquid level inductor, realize automatic automatically according to evaporation capacity in seawater pond, high
Effect accurately carries out moisturizing.
The spilling water collecting box, water-absorbing core adsorb excessive liquid when, by spilling water nozzle flow out to spilling water collecting box into
Row is collected, while strong brine rinse mouth pours raw material seawater from import and washes away to strong brine in seawater pond, then via water outlet stream
Enter spilling water collecting box.
The reflection heat-aggregation core pattern solar seawater desalination system compound with Fresnel optically focused in theoretical calculation and is tested
It is obtained after verifying, 1m2Disengagement area can produce fresh water 6.1KG/D.Consumption calorific value is equivalent to 15.1KG mark coal, 4.85KG liquid on year-on-year basis
Change gas, there is larger actual use value, it is energy saving.
