Description
Technical field
The invention belongs to the enclosed ocean thermal energy Blast Furnace Top Gas Recovery Turbine Unit (TRT) of exploitation of marine energy technical field.
Background technology
At the ocean surface under the irradiation of the sun and be not subjected to for a long time having the temperature difference between the deep-sea of irradiate light.Generally in the torrid areas, the dark seawater temperature difference of an ocean surface and a km can reach 25 ℃.Ocean thermal energy conversion (be called for short OTEC) is to utilize the seawater temperature difference and produce power.According to the heating power formula, hot machine operates between 7～27 ℃, then its in theory maximal efficiency be 6.7%.Different with morning and evening tides or wind energy, the heat energy of being stored in the ocean utilizes serially.
Conventional ocean temperature difference power generating system as shown in Figure 1.System is made up of several parts such as evaporator, turbine, generator, condenser, working medium pump, warm sea water pump, Mare Frigoris water pumps.Connect by huge pipe between each several part.Evaporator generally is to be made of the large cylinder that many little pipes or thin plate are equipped with in inside, making certain is that evaporated liquid material (this liquid substance is called working medium) flows into therebetween between 13～15 ℃, and import 15～28 ℃ surface seawater when (surface seawater also is called warm seawater), working medium forms steam because of being subjected to warm seawater ebuillition of heated, steam is delivered to turbine via connecting line and is made its rotation, thus output power.
On the other hand, the steam from the turbine effusion then imports condenser.When the steam of being overflowed by turbine flows into therebetween and import 1～7 ℃ deep sea water when (also claiming Mare Frigoris water), these steam become the working fluid of liquid state with sending evaporator again back to by pump because of the cooled with seawater of catching a cold in the surface condensation of pipe or thin skin.Such operation goes round and begins again and constantly carries out, as long as have the temperature difference between surface seawater pipe (warm seawater) and deep sea water pipe (Mare Frigoris water), can constantly obtain electric power from seawater via above-mentioned circulation.
The needed Mare Frigoris water of conventional ocean thermal energy Blast Furnace Top Gas Recovery Turbine Unit (TRT) shown in Figure 1 is that (apart from sea level 600m～800m) extraction obtains, this need consume a large amount of electric energy, and power consumption accounts for turbine and sends 40%～50% of power from the deep-sea by the Mare Frigoris water pump.In addition, the pipe diameter that extracts Mare Frigoris water is very big, is difficult for fixing.
And condenser is placed the enclosed ocean thermal energy Blast Furnace Top Gas Recovery Turbine Unit (TRT) at deep-sea, and can save Mare Frigoris water pump and corresponding large diameter pipeline, Mare Frigoris water pump wasted work is zero.The increase that places the enclosed ocean thermal energy Blast Furnace Top Gas Recovery Turbine Unit (TRT) at deep-sea can bring the working medium pump merit in condenser.Contrast Mare Frigoris water pump and working medium pump wasted work situation, though working medium pump than Mare Frigoris water-aspirator pressure height,, Mare Frigoris discharge is than the big tens～hundred times of working medium flow, so working medium pump will be about half of the total wasted work of Mare Frigoris water pump.As seen this device has the basis of extensive utilization.But the relevant report that this respect is not arranged at present.
