Embodiment
Below in conjunction with accompanying drawing the utility model is explained further details:
Electricity, water, salt co-production sea water desalination system, as shown in Figure 1, comprise cold method preparing fresh water, thermal power generation, salt manufacturing three parts.
Said thermal power generation part mainly comprises boiler 1, turbine 2, condenser, and the vapour side of condenser connects condensate pump 4, deoxygenator 5, high pressure heater 6, boiler 1 in order, and the water side of condenser circulates in order and connects cooling tower 8, circulating pump room 9.The superheated vapour of boiler 1 gets into turbine 2, and turbine 2 drives generator 16 and carries out electric power output.Condenser is arranged on a side of turbine 2; The hot water of condenser water side arrives cooling tower 8 through pipe connection; The cooling of the 8 pairs of hot water of cooling tower, refrigerative simultaneously can some windage loss, vaporization losses, and cooled cold water gets into circulating pump room 9 and continues as condenser and use.Condenser vapour side then provides water through condensate pump 4, deoxygenator 5 and high pressure heater 6 for boiler 1 work.
Cold method preparing fresh water and salt manufacturing begin from seawater, comprise to seawater carry out precooling fore-cooling room 10, be used for the refrigeration chamber 11 of freezing seawater.One side setting icehouse 12 of refrigeration chamber, the low-temperature cold water that change icehouse 12 is changed behind the ice is communicated on the raceway groove between cooling tower 8 and the circulating pump room 9 through pipeline.The water side and the pipeline between the cooling tower 8 of condenser are provided with two branch roads, and being connected to of branch road icehouse 12 wherein, another branch road connect tap water production technique system 13.The fresh water water outlet setting of tap water production technique system 13 is connected to the bypass of Water Treatment device 14.The water outlet side of Water Treatment device 14 is connected to deoxygenator 5.Said refrigeration chamber 11 is communicated with pipeline between Water Treatment device and the deoxygenator through vacuum fan 15.
Seawater at first gets into fore-cooling room's 10 precoolings, and the seawater after the precooling gets into refrigeration chamber 11, and seawater is freezing as for freezing point, produces ice bits, water vapor, crystal salt.Transport the crystal salt in the refrigeration chamber 11 back fore-cooling room 10, the salt grain of crystal salt is carried out drying acquisition crude salt, can carry out the crude salt refining subsequently.With outer the transporting to icehouse 12 of the bits of the ice in the refrigeration chamber 11, get into circulating pump room 9 after the low-temperature cold water behind the change icehouse 12 change ice and the cold water mix of cooling tower 8 and cold water is provided for condenser.The hot water that comes out from condenser water side divides three the tunnel, the one tunnel to be cooling in cooling tower 8; One the tunnel to get into the tap water production technique be that 13 systems carry out fresh water and produce, and the fresh water of production can directly dispatch from the factory; Also has one road being connected to icehouse 12.The fresh water of tap water production technique system 13 dispatches from the factory and bypass also is set on the pipeline, and part fresh water is introduced Water Treatment device 14, adds in the deoxygenator 5 as make up water through chemically treated fresh water.And the water vapour of top is also taken out by vacuum fan 15 in the refrigeration chamber, and the make up water after mixed chemical is handled gets into deoxygenator 5 together.Through this a series of technical process, make that the cold and hot configuration of whole factory is more reasonable, all reduced greatly from the production cost that generates electricity, makes water, salt manufacturing.
