beneficial effect:
1. can improve and evaporate brine efficiency and obtain the speed that a large amount of fresh water depends primarily on evaporation, improve vaporization efficiency and depend primarily on temperature, air velocity and evaporation area, the radiations heat energy that the present invention takes full advantage of sun power improves vaporization efficiency, booth top is provided with water guide, hydrophobic pipeline obtains fresh water, discharges water of condensation, when reducing moisture, raising vaporization efficiency, accomplish the collection of fresh water.Make full use of China coast environment and solar distilling method obtains fresh water, when strengthening salt extraction yield, obtain fresh water, the prospect of this application is very wide.
2. the present invention uses warmhouse booth, utilizes thin film technique fully to absorb solar radiation heat, and keeps temperature higher in booth, improves vaporization efficiency.
3. the present invention arranges distilled water and collects pipeline, while making to evaporate the condensation of gained water vapor chance ceiling, flows to hydrophobic semicanal, then flow to decline pipeline along guide water board, enters collection device, well utilizes evaporation to obtain fresh water, is used.Hydrophobic pipeline is also installed on condenser, is collected the fresh water of condensation, reduce moisture.
4. the present invention uses heat pump dehumidifier dehumidifying, gets rid of wet air, and warm condensation vapor becomes cold water to drip from air to separate, and wet air declines through dehumidifier humidity, and dry air is sent into booth, accelerates evaporation.Utilize condensed water heat release to heat the air in booth, the relative humidity of air in booth is declined, accelerate evaporation, improve salt extraction yield.Along with constantly carrying out of evaporation, make the excessive even dewfall of atmospheric moisture in booth, stop evaporation, adopt the method for heat pump dehumidifier dehumidifying, make dry air, water recovery release of heat adds the bittern in pond.Heat insulation function by booth is accelerated evaporation.The heat that condensation vapor and process of cooling discharge is absorbed by refrigerant, accelerates vaporization efficiency, improves salt extraction yield, and has accelerated the collection of fresh water.
these dehumanization methods are low compared with alternate manner cost, and income is high.By dehumidifying, can be in the same raising vaporization efficiency that improves temperature.
5. the present invention has utilized sun power preferably, in outside, salt pond, lays warmhouse booth, and booth adopts Yimianpu---arch structure.This structure can fully absorb solar radiation, warm room temp is raise larger.Warmhouse booth film adopts the rolled mould of high transmission rate, guarantees that illumination transmissivity is good, has good heat insulation effect.
6. utilize the present invention, pond water surface evaporation heat waste is recycled, transfer in the water and air of pond, make up pond water and air heat waste, realize dehumidification function simultaneously.First through heat exchanger heats Chi Shui, waste heat, through atmospheric condenser, heats cooling wet air, realizes intensification function.
unsuitable too high for guaranteeing the relative humidity of booth inside, do not cause owing to evaporating and being affected in the high booth of humidity, and guarantee that evaporation comparatively fast carries out, so, can accelerate bittern evaporation by better utilised sun power, improve the utilization ratio of heat energy, improve the efficiency of evaporating brine, obtain valuable Freshwater resources, for salt making enterprises wound effect increases income, obtain economic Freshwater resources simultaneously, have a extensive future.
