Embodiment Construction

[0008] Below in conjunction with embodiment this invention is further described:

[0009] Such as figure 1 As shown, the original power generation system remains basically unchanged. Notes 1-21 in this figure except 8 and 19 are the flow chart notes of the power plant. Only a valve was added to the upper pipe of the original condenser, and a new bypass system was built. Close the upper valve 22 and open the bypass valve 23 so that the exhaust steam passes through the pipeline and is pressed into the condenser 28 on the mine rack platform 43 with a certain height in the bypass. Close the valve 24 on the cooling water system pipeline, open another valve 25 on the cooling water pipeline, and the cooling water is pressed into the bypass condenser under the pressure of the circulating water pump 8 for cooling. Close the valve 26 on the air extraction 41 and open the valve 27 on the air extraction pipeline to take out the vapor that is not condensed into water in the bypass conde...

Abstract

The invention relates to a waste steam, condensate water and cooling water regenerating device of a thermal power plant and a nuclear power plant. The device provided by the invention is characterized in that after steam drives a turbine to generate power, the swelling pressure of the turbine is reduced, but the steam quality of the turbine is not reduced; the waste steam is pressed into a platform with a certain height relative to the ground through a pipeline under 3 to 4 atmospheric pressures (while the higher height is better but according to actual conditions); after being cooled through a highly vacuum condenser, the waste steam is changed into liquid water at a temperature of about 40 DEG C; after being exhausted and stored into an upper water storage tank at the lower part, the liquid water leaks downwards through a pressure pipeline to drive the turbine; the turbine drives a generator to generate the power; the cooling water is lifted to the height which is the same to the condenser through a circulating water pump; the waste heat is taken away by the condenser; after being exhausted and stored into another upper water storage tank at the lower part, the waste heat leaks downwards through the pressure pipeline to drive the turbine; and the turbine drives the generator to generate the power (while the cooling of the condenser is divided into water cooing and air cooling, if the air cooling is adopted, a cooling water generating device is not provided).

Description

Technical field: [0001] The invention belongs to the technical field of energy power generation, and utilizes the gravitational potential energy of the condensed water of exhausted steam and the mass of cooling water after the steam turbine generates electricity to drive the generator to generate electricity through the water turbine. Background technique: [0002] The condensed water of nuclear power plants in power plants is used as circulating water, and some of the cooling water is used as closed-circuit circulating water and some are discharged into rivers. The inherent energy of the condensed water in the transformation from gas to liquid is not fully utilized, which wastes a lot of energy and reduces the power generation efficiency. Invention content: [0003] This technology utilizes the principle that when the exhaust steam of thermal power plants and nuclear power plants is converted from gaseous state to liquid condensed water, the specific gravity of hot steam ...
