Description
Technical field
The utility model is related to energy technology field and in particular to a kind of temperature difference electricity generation device.
Background technology
Existing ocean temperature differential power technology, according to the difference of working medium used and flow process, generally can be divided into open circulation, closes
Formula circulation and hybrid circulation, close to practical be closed cycle mode.
Open-cycle system intermediate pump will be extracted into certain vacuum in system, starts the warm seawater suction top layer for the heat-exchanger pump
Evaporimeter, due to having maintained certain vacuum in system, so warm seawater just explosive evaporation in evaporimeter, is changed into steaming
Vapour, steam sprays pushing turbine operating through pipeline by nozzle, drives electrical power generators.The waste vapour discharged from steam turbine enters cold
Condenser, the Mare Frigoris water being drawn up from deep sea water by water supply pump cools down, and is re-condensed into water, and enters marine.At this it is
As the seawater of working medium in system, evaporator evaporation is entered to finally flowing back to sea by pumping, does not recycle, therefore this work system
Referred to as open-cycle system.
Closed circulation system then adopts some lower boiling materials (as propane, iso-butane, freon, ammonia etc.) as work
Fluid, is repeated evaporation, expansion, condensation in the closed circuit.Because system uses low boiling working fluid, the pressure of steam
It is improved.During system work, heat-exchanger pump draws up top layer temperature seawater and is sent to evaporimeter, by the coil pipe in evaporimeter one
Divide heat transfer to lower boiling working fluid, such as ammoniacal liquor, ammoniacal liquor, after the enough heats of warm Absorption by Sea Water, comes to life simultaneously
It is changed into ammonia.Through the blade path of steam turbine, expansion work, pushing turbine rotates ammonia.The ammonia that steam turbine is discharged enters
Enter condenser, after the deep layer Mare Frigoris water cooling being drawn up by water supply pump, be again changed into liquid ammonia, then with pump the liquid in condenser
Ammonia is pressed into evaporimeter, for recycling.
Mixture circulatory system is substantially identical with closed cycle, but heats low boiling with the low-pressure steam that warm seawater flashes off
Point working medium.This have the advantage that the volume decreasing evaporimeter, can material-saving, be easy to safeguard.
In the electricity generation system of existing power generation with sea water station, all there are two big shortcomings：First, power generation with sea water station electricity generation system
Equipment evaporator, decompressor, condenser, turbine efficiency are low, are all (as water, propane, isobutyl by working medium in all circulatory systems
Alkane, freon, ammonia etc.) it is changed into the rotation of Steam Actuation steam turbine, and the steam that is still that steam turbine is discharged enters condenser, heat energy
It is converted into mechanical energy efficiency low；Second, power generation with sea water station electricity generation system is required for working medium pump or vavuum pump, consumes substantial amounts of electricity
Can, production cost is high.
The factories such as existing steam power plant, steel plant usually produce unnecessary used heat, and these heat energy are seldom utilized；
The hot water that solar water heater produces also usually cannot sufficiently utilize, and this all can cause the waste of the energy.
Utility model content
The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, provides a kind of temperature difference to send out
Electric installation, overcomes ocean temperature differential power apparatus structure complexity in prior art, cost of electricity-generating height, energy conversion efficiency low and existing
