Said regenerator, it is connected with said condenser, is used for the organic working medium after the regenerator cooling is sent into said condenser;
Said condenser, it is connected with said working medium pump, is used for condensed organic working medium is sent into working medium pump;
Said working medium pump, it is connected with said regenerator, is used for organic working medium is sent into the regenerator preheating;
Said regenerator also is connected with said heat exchanger, is used for that the working medium after the preheating is sent into said heat exchanger and recycles.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said steam turbine adopts the radial inflow steam turbine.The radial inflow steam turbine here belongs to the ultra high speed steam turbine, and rotating speed is generally more than 30000r/min.The structure of said inflow wheel machine is very simple, mainly is made up of an inflow wheel and a spiral case, is similar to the centrifugal pump of a reverse flow on the structure.Directly milling shaping on impeller of blade, the accurate casting of whole impeller forms, and spiral case is generally foundry goods, and nozzle ring is housed in the spiral case, gets into the velocity magnitude and the direction of impeller to guarantee steam.The established angle of nozzle can be adjusted when operation, to improve the off design performance of steam turbine.Because high rotational speed and particular structural impel said radial inflow Efficiency of Steam Turbine to have higher energy conversion efficiency up to more than 80%.
Further, said heat exchanger is intrusive mood fluid heat exchanger or shell of pipe type fluid heat exchanger.For the intrusive mood fluid heat exchanger, industrial fluids moves outside heat exchanger, and the heat absorption organic media moves in heat exchanger; For the shell of pipe type fluid heat exchanger, industrial fluids moves at internal layer, and the heat absorption organic media moves at skin.
Further, said steam turbine and said generator are through directly driving mode or belt is connected.
Further, said condenser is water-cooled condenser or air-cooled condenser, can select air-cooled condenser for use to the water-deficient area.
The beneficial effect of the utility model is: the described low potential temperature industrial fluids residual neat recovering system of the utility model can change into electric energy with inferior heat energy; The organic working medium that adopts is in turbine acting process; From the high pressure to low pressure, remain drying regime; Eliminate the possibility that forms moisture, produced the possibility of corrosion and damage when having avoided the little water droplet of high speed to impact steam turbine; And the organic working medium condensing pressure is not high, and whole system is worked under a little higher than atmospheric pressure, and the leakage phenomenon of organic working medium is greatly reduced.Radial inflow steam turbine working pressure accommodation is big, more than 1.1Mpa, gets final product work.Condenser need not increase antifreeze facility yet in the system.Native system does not need vacuum system, does not need DW system demineralized water system, does not need factory building, and the civil engineering workload is little, little investment, and payoff period is short; Unmanned during operation, maintenance is very little, and maintenance cost is cheap.
