Description
Technical field
The utility model relates to a kind of draining surplus energy utility system, particularly relates to a kind of direct cooling unit draining surplus energy utility system.
Background technique
Once-through cooling system also claims direct-flow water supply system, refer to that cooling water directly obtains from water source, flow through cooling equipment or heat exchanger after disposable thermal exchange, be discharged to intake downstream, no longer reusable a kind of cooling way of supplying water, this type of cooling water usage is large, when the water source water yield is sufficient, adopts, and is applied to seashore or rivers limit generator set more.Once-through cooling system is mainly comprised of intake, filter plant, circulating water pump and auxiliary system thereof.
Hydroelectric power is to utilize rivers and creeks, lake etc. to be positioned at the current that eminence has potential energy to flow to lower, wherein contained potential energy is converted to the kinetic energy of water turbine, and kinetic energy drives water turbine to rotate thus, as prime mover, drives generator amature to rotate generating.Water turbine can be divided into impulse turbine and the large class of reaction turbine two by working method, and reaction turbine can be divided into again mixed-flow, axial flow, diagonal flow type and tubular, and application is Francis turbine more widely at present.
Direct cooling Construction of Unit is on rivers limit or seashore, consider that plant area is not subject to the impact of morning and evening tides and domatic flood, take into account the factor of the aspects such as the processing of factory building deep foundation and water intaking Economy simultaneously, factory building zero rice is mostly on normal sea level or rivers 10 meters of left and right above water, after arranging like this, once-through cooling water enters drainage by siphon after the vapour condenser of flowing through, draining still has certain potential energy, but most of power plant does not all adopt rational surplus energy utility measure, for fear of draining to damaging property of drain opening part, all be provided with water drainage energy dissipation device, when having wasted complementary energy, increased initial cost.
Model utility content
The purpose of this utility model is to provide a kind of direct cooling unit draining surplus energy utility system.
The purpose of this utility model is implemented by following technological scheme, a kind of direct cooling unit draining surplus energy utility system, it comprises direct cooling vapour condenser, circulating water pump and water turbine, intake is connected with the water intake pipeline of described direct cooling vapour condenser, the pipeline that connects the water intake of described intake and described direct cooling vapour condenser is provided with described circulating water pump, the water outlet of described direct cooling vapour condenser is connected with the water intake of waste pipe, the water outlet of described waste pipe is connected with the water intake of described water turbine, and the water outlet of described water turbine is connected with drain opening.
Described water turbine is impulse turbine or reaction turbine.
