Abstract
The high efficiency steam power cycle apparatus for generating electricity consists of vaporizing and heating unit, steam turbine, condensing tower, working medium pump, working medium storage tank and high pressure metering pump successively connected serially to form one loop. The steam turbine is connected to the electrical generator, and the working medium in the steam power cycle apparatus is perfluoro butane or perfluoro pentane. The high efficiency steam power cycle apparatus has one 50-90 % raised electricity generating efficiency, saving in energy source and lowered cost.
Description
Technical field
The present invention relates to a kind of power circulating device, especially for the steam power circulating apparatus of generating.
Background technique
In existing generation technology, mostly utilize water vapor to carry out power cycle, driving generator by steam turbine generates electricity, because the vaporization heat of water is bigger, make water become water vapor and need more energy, cause the efficient of water vapor power link to have only 30%-45%, restricted the raising of generating efficiency, wasted a large amount of energy.
Summary of the invention
The present invention has overcome the problem of above existence, a kind of steam power circulating apparatus of efficient power generation is provided, its technological scheme of taking is: this device is connected into the loop successively by vaporization warming device, steam turbine 2, condensing tower 3, working medium pump 4 and working medium basin 5, steam turbine 2 connects generator 6, be connected with high-pressure metering pump 7 between boiler 1 and the working medium basin 5, the employed working medium of this steam power circulating apparatus is perfluorinated butane hydrocarbon or perflenapent hydrocarbon.
The vaporization warming device can be the boiler 1 that is divided into low temperature area and high-temperature zone, also can be by interconnecting vaporizer 8 and temperature rising device 9 is formed.
Owing to replace high boiling water with lower boiling perfluorinated butane hydrocarbon or perflenapent hydrocarbon, therefore save the more energy.Originally it is stable that the new working medium that recycles can keep in the time of 800 ℃, and the operating temperature upper limit can be to 750 ℃, the working medium characteristic good.Originally use high-pressure metering pump 7 before circulating in the working medium vaporization, improved the low temperature heat absorbing property and the pressure for vaporization of working medium, satisfied the required pressure of steam turbine 2 work, greatly promoted the output power of steam turbine.This circuit efficient mainly is that the thermal gradient energy of steam work significantly promotes circuit and exerts oneself by the decision of the heat release temperature difference of the critical temperature of working medium and condensing temperature, and is less important to the influence of efficient, and this is with the Carnot's cycle difference.
Use generating efficiency of the present invention and can improve 50%-90%, saved the energy, reduced cost, have good social benefit and economic benefit.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one,
Fig. 2 is the structural representation of the embodiment of the invention two.
Embodiment
Describe the present invention below in conjunction with accompanying drawing:
Embodiment one: as shown in Figure 1, this steam power circulating apparatus uses perfluor neopentane (perfluor 2,2-dimethylpropane) as new working medium, replaces original working-medium water.
The working medium perfluor neopentane of working medium basin 5 is through after high-pressure metering pump 7 pressurizations and controlling the computation requirement amount, at first enter the low temperature area of boiler 1, the vaporization of being heated of temperature about 135 ℃, heat the back then in the high-temperature zone of boiler 1 and feed 10 voltage stabilizings of voltage stabilizing gas bag, this moment, perfluor neopentane vapor (steam) temperature reached 450 ℃-550 ℃, pressure is 6-7.5MPa, and applicable to the work of steam turbine 2, and then pushing turbine 2 drives generator 6 generatings.
Perfluor neopentane steam is by behind the steam turbine 2, and temperature is reduced to about 120 ℃, and steam is saturation state, enters condensing tower 3 liquefaction, and condensing temperature generally is controlled at about 118 ℃ and is advisable, and pressure control is in the 1.5-1.8MPa scope.It is standby that perfluor neopentane liquefaction back uses working medium pump 4 that it is delivered to 5 storages of working medium basin.
Embodiment two: as shown in Figure 2, at the power plant that has built up, it is carried out renovation and utilization, to stop its cooling water to a large amount of heat release discharging in the external world, realize duplexing matter circulation, now be illustrated:
This steam power circulating apparatus uses perfluorinated butane as new working medium, replaces original working-medium water.
Draw 115 ℃-120 ℃ weary gas from former steam turbine 12 ends of power plant, measure as required by measurement controller 13 and to send into vaporizer 8, vaporizer 8 can be used as the condenser of water vapour, behind the vaporization perfluorinated butane, perfluorinated butane steam is sent into temperature rising device 9 and is heated, and heats heat and derives from former circuit superheated vapour, and water vapor what by controllable pump 15 controls, feed 10 voltage stabilizings of voltage stabilizing gas bag again, and then pushing turbine 2 drives generator 6 generatings.After the weary gas-liquid of introducing from former steam turbine 12 changes into water, send into former boiler 14 by water pump 11 again, one-way valve 16 prevents that circulating water from driving in the wrong direction.Perfluorinated butane steam enters condensing tower 3 liquefaction after by steam turbine 2, condensing temperature is controlled at about 105 ℃-108 ℃, it is standby to use working medium pump 4 that it is delivered to 5 storages of working medium basin after the perfluorinated butane liquefaction, squeezes into vaporizer 8 after being needed to pressurize by high-pressure metering pump 7 foundations again and finishes circulation.
The power of steam turbine 2 can be according to the 50%-80% design of former steam turbine 12 power.
More than measure control among two embodiments preferably finish by power plant's electronic automatic control system monitoring.
