The prior art of seawater, brackish water desalination is mainly two kinds of embrane method and the way of distillations, and the way of distillation is again based on multistage flash evaporation and multiple-effect evaporation dual mode.These technological systems are all comparatively complicated, the cost height, and all to consume a large amount of electric energy, pay the certain energy cost.Solar energy is the desirable thermal source of seawater, brackish water desalination as inexhaustible clean energy resource.
Summary of the invention
The purpose of this utility model is to overcome in the technology that adopts sunlight direct projection distillation preparing fresh water because intensity of illumination is little, heat density is low, the plant area area that causes is big, still-process slow and produce the inefficient problem of water, the utility model proposes and adopt the intense light irradiation jetting, make the water rapid evaporation of being heated, pure water is produced in the steam condensation of output.Simultaneously, utilize condensation process steam liberated heat to produce hot water, realize the integrated production of pure water and hot water.
The utility model is realized in the following manner:
Concentrating solar is produced hot water and pure water device, by condenser, solar automatic tracker, heat collector, vapor-water heat exchanger constitutes, condenser is parabola face speculum or Fresnel Lenses, condenser is fixed by support, its fixed support is provided with rotating mechanism, control by sun tracker, condenser and heat collector are connected as a single entity by steel bracket, heat collector is small-sized closed container, the front end face of heat collector is provided with the light entrance port, and the rear end of heat collector is provided with water inlet, and the top of heat collector is provided with venthole, the bottom of heat collector is provided with hot water outlet, and the focus place of condenser and parallel with the minute surface of condenser is located in the light entrance port of heat collector.Vapor-water heat exchanger is a tube shell type structure, the upper end of condenser pipe connects the venthole of heat collector by soft connecting leg, the end of condenser connects the pure water case, the lower end, the outside of condenser is provided with water supplement port, the outer upper end of condenser pipe is provided with the pipeline that is connected with the water inlet of water collector, separate with dividing plate between pure water case and the condenser, the lower end of pure water case is provided with the pure water outlet.High water level sensor and low water level sensor are housed above the heat collector, and high water level sensor and low water level sensor are connected with magnetic valve on being arranged on the water inlet pipeline.High temperature resistant transmission material is adopted in the light entrance port of heat collector, and the water inlet of heat collector, delivery port and hot water outlet all are equipped with universal joint.
Remove seawater, the bitter of impurity after filtration, squeeze into the heat exchanger water supplement port, also can adopt municipal water supply directly waterpipe to be connected with the heat exchanger water supplement port by water pump.The water heat absorption heats up the back from the outflow of heat exchanger delivery port, enters heat collector, directly accepts the high strength solar light irradiation, is rapidly heated, gasifies.
The utility model utilizes the mode of concave mirror or convex lens optically focused, adopt parabola face speculum or Fresnel Lenses to improve intensity of illumination, light gathering efficiency is up to more than 85%, and at the focus place, light-ray condensing forms a diameter less than 5 centimetres hot spot, condenser uses steel bracket to fix, fixed support can freely rotate, and by solar automatic tracker control rotation direction, guarantees that minute surface is vertical with the incident direction of sunlight all the time, make minute surface obtain maximum using, obtain best spotlight effect.
Heat collector is a small-sized closed container, and light entrance port, water inlet, venthole and hot water outlet are set on it.Wherein, the light entrance port is with high temperature resistant transmission material shutoff, and is over against the hot spot of condenser, more slightly bigger than hot spot.The high-strength beam at hot spot place enters heat collector fully by going into perforation, and heat is directly absorbed by water, and through repeatedly reflection, the energy of light is finally absorbed by water the light that enters heat collector, the utilization rate height of luminous energy in heat collector.
Heat collector links into an integrated entity by steel bracket and condenser, and keeps both relative positions to fix.The focus place of condenser and parallel with minute surface is located in the light entrance port of heat collector.Because the focus and the condenser itself of condenser are fixed, when condenser was followed sun rotation by solar automatic tracker control, the light entrance port of heat collector was also all the time over against hot spot, and the light of gathering shines heat collector constantly fully.
Because it is less to hold water in the heat collector, and water inlet passed through the heat exchanger preheating, and when receiving strong sunshine, heat energy makes water be gasificated into steam rapidly.Steam is drawn from the venthole on heat collector top, enters the heat exchanger condensation.
Heat exchanger is made up of the condenser on top and the pure water case of bottom.Condenser is a tube shell type structure, and (hot side) is the water vapour of high temperature in the condenser pipe, and pipe outer (cold side) is a bitter to be heated.Water vapour heat release cooling is condensed into water, is pure distilled water; After heating up, the bitter heat absorption enters heat collector, for evaporation provides the heating in early stage.In this heat transfer process, solar energy is mainly used to provide evaporation heat, and the heat that adds of hot water is the cooling steam gained, and cascaded utilization of energy has further improved the thermal efficiency of whole system.
The pure water case and the heat exchanging segment of heat exchanger bottom are separated fully by dividing plate.The end of condenser pipe stretches into the pure water case, and the distilled water of condensation flows down along inside pipe wall and is saved in the pure water case, is the source of purified water that can Gong drink at any time.The pure water that evaporative condenser the obtains desalination of not only desalting also through the high-temperature sterilization sterilization, can be drunk safely.
A high water level meter and a low water level meter are installed on the heat collector, the heat collector water inlet is installed a magnetic valve, by water level meter control magnetic valve, when wherein water because when continuing evaporation and reducing to low water level, magnetic valve is opened, moisturizing in heat collector, close to the high water level rear electromagnetic valve and to stop moisturizing, guarantee that the perforation place has water to expose to sunlight all the time, thereby guarantee the absorptivity of water, also prevent the water evaporate to dryness in the heat collector light.
The bitter that is heated by steam in the heat exchanger also can be used as the hot water supply, and hot water outlet is installed in the heat collector lower end, when using hot water, immediately the strong brine of assembling is taken away, and prevents fouling in the heat collector.
Because heat collector rotates at any time, the water inlet of heat collector, venthole and hot water exit install universal joint, are connected with the hot water supply pipe with the pipeline of vapor-water heat exchanger by soft connecting leg.
