Embodiment
This integrated apparatus comprises evaporating area and cellar ice condesation zone two portions.
Evaporating area has one group to be arranged in stepped a plurality of sealing evaporator tank 2, and there is vapour pipe 4 top of each evaporator tank, and there is the aqueduct 5 of band pipe valve 3 below of each evaporator tank, and aqueduct connects the evaporator tank of stepped a plurality of sealings from top to bottom successively; Each evaporator tank loam cake is transparent openable sealing cover, and evaporation tank 1 is arranged on the evaporator tank of the top, and evaporation tank has pipe connection in the evaporator tank of the top.
Cellar ice condesation zone 6 is in the inboard of a plurality of sealing evaporator tanks of staged, and the vapour pipe of each evaporator tank extends in the cellar ice condesation zone, and passes in cellar ice condesation zone, and all vapour pipes link together, and also connects induced draft fan 9 on the house steward 7 that vapour pipe connects.It below cellar ice condesation zone ice-melt pond 8.
Evaporating area is formed by the top layer evaporation tank with towards sunny side staged multilayer evaporator tank.Evaporator tank (pond) is added with transparent cover can printing opacity, absorbs solar radiation heat energy; Sealing so that with the vapor collection that evaporates in the evaporator tank (pond), does not make it be emitted in the atmosphere again.Seawater is introduced in the evaporator tank (pond) from top to bottom, is subjected to solar light irradiation separately and spontaneous evaporation then.The steam that is evaporated adds the mode that blower fan draws with negative pressure and delivers to cellar for storing things ice, condensing zone.Store the sea ice of capacity in cellar for storing things ice, the condensing zone, be condensed, form water of condensation at this steam; Simultaneously, steam makes its thawing again the heat transferred ice body, forms ice-melt water.Evaporator tank (pond) is in evaporative process, and concentration is more and more higher from top to bottom, and to the foot evaporator tank, concentration is the highest, and goes out salt in this crystallization.After going out salt, upper level evaporator tank salt solution adds automatically, and upper level is replenished by upper level again, augments step by step successively.Continuation evaporations at different levels continue to draw, and continue condensation, continue salt.So circulation, continuous production.
For making full use of cold, be provided with the ice-melt pond in this bottom of device, steam-pipe in advance this by and given coldly, arrive the continuation condensation of ice formation, cellar for storing things thereafter again.Simultaneously, the ice-melt pond also has sedimentary function, can improve ice-melt water effluent quality.
This device also can be taken in rainwater concurrently.When raining, top, the domatic rainwater that obtains are collected in the ice-melt pond, bottom, thereby can be increased fresh water yield.Because directly into the pond, its water quality also can guarantee rainwater without ground.
Season in severe winter, evaporator sump, tank are all introduced seawater, make its degree of depth about 30 centimeters, and open wide its lid, be exposed among the severe cold of the Nature, its maritime interior waters is glaciation gradually then.Utilize matching special equipment that ice body is taken out successively then, standby in the ice formation, block pattern row pattern cellar for storing things.At this moment, only remaining high density bittern and salt body crystalline mixture in pond (groove) through reclaiming, can obtain salt again.
Be connected with two kinds of pipelines between the evaporator tank (pond).One is the salt water passage, and it two is drawn for steam.The steam fairlead divides upper and lower two portions.The steam-pipe of Lower Half evaporator tank upwards after the ice formation condensation of cellar for storing things, utilizes negative pressure mode to discharge from the residual air pipe; First half evaporator tank and evaporated on top pond vapour pipe after ice-melt pond, cellar for storing things ice formation condensation, utilize negative pressure to add the blower fan lead-out mode and discharge from the residual air pipe downwards.Because institute's exhaust gas still contains cold, can be used as the by-product utilization of this device.
For the steam of controlling the evaporation of evaporator tank (pond) maritime interior waters better produces and the balance of drawing, control interior brine concentration of each evaporator tank (pond) and liquid level, the temperature and the quantity discharged of control water of condensation and ice-melt water, this device adopts microcomputer control system.
In sum, this integrated apparatus has utilized natural energy resources morely, used advanced control techniques, had freezing, evaporation, condensation, ice-melt, rainwater is collected and salt production etc. is all multi-functional, can deserve to be called to integrate the new production technique and the device of novel appts.
