Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
As shown in fig. 1 and 2, a two-loop thermodynamic system of a nuclear power plant includes a heat exchange pipe 300 connected between a condenser 100 and an evaporator 200, a low-pressure regenerative system for heating condensed water in the heat exchange pipe 300, a high-pressure regenerative system, and a deaerator 40, where the low-pressure regenerative system includes a low-pressure cylinder g1, a No. 1 low-pressure heater j1, a No. 2 low-pressure heater j2, a No. 3 low-pressure heater j3, and a No. 4 low-pressure heater j4, the high-pressure regenerative system includes a high-pressure cylinder g2, a No. 6 high-pressure heater j6 and a No. 7 high-pressure heater j7, which are disposed on the heat exchange pipe 300, and the two-loop thermodynamic system further includes a heating system, which includes a heat generating device, and a heat collecting and exchanging device 51 for heating the condensed water in the heat exchange pipe 300 by the heat generated by the heat generating device.
The heat generating device is a solar photo-thermal device. The solar photothermal device includes a linear fresnel reflective concentrating system 50. By utilizing the unique characteristics of the solar photothermal technology, the reflecting mirror group of the linear Fresnel reflection condensing system 50 is arranged on the factory area of the nuclear power station or the roof of a steam turbine machine room, the energy gathered by the solar photothermal device is directly used for heating the water supply of the two-loop thermodynamic system of the nuclear power station through the heat collection and exchange device 51, the water supply temperature is increased, the steam is pumped by the steam turbine regenerative system, the pumped steam is returned to the steam turbine for continuous work, and the heat efficiency and the economical efficiency of the nuclear power station are improved.
In order to improve the light and heat collecting efficiency, the reflecting condenser mirror surface is designed to be a secondary song surface type with the light condensing characteristic, and the optical light condensing efficiency is more than or equal to 90 percent. The surface coating of the heat collection and exchange device 51 is an improvement of a solar selective absorption coating, can resist the high temperature of 300 ℃, and has the absorption rate of over 96 percent in the solar spectrum range.
In addition, the invention adopts a single-shaft automatic tracking system, so that the linear Fresnel reflection light-gathering system 50 can collect solar radiation energy with maximum efficiency in different seasons and different sunshine periods, and the control mode can select preset process control or photoelectric sensing control. The preset process control is to calculate the position and angle of the reflector according to the solar operation rule and control the rotation of the mirror shaft through the movement of the mechanical mechanism. The photoelectric sensing control is that the photoelectric sensor instantly collects and measures the sunlight direction, and the mechanical mechanism is controlled to move after the sunlight direction is processed by a circuit. The disadvantage of the photoelectric sensing control mode is that the correct position of the sun cannot be found in cloudy or rainy days, and manual intervention and adjustment are needed.
The heat collection and heat exchange device 51 can be arranged at the downstream of any one of the low-pressure heater j1 No. 1, the low-pressure heater j2 No. 2, the low-pressure heater j3 No. 3, the low-pressure heater j4 No. 4, the high-pressure heater j6 No. 6 and the high-pressure heater j7 No. 7, and the heating efficiency of the heat collection and heat exchange device 51 is higher as the heat collection and heat exchange device is closer to the outlet of the heat exchange pipeline 300; in this embodiment, due to the limitation of the field space of the existing two-circuit regenerative system, the heat collecting and exchanging device 51 is preferably disposed downstream of the No. 4 low-pressure heater j4 or downstream of the No. 7 high-pressure heater j7 without being greatly modified on the field.
If the heating system heats the final water supply temperature of the two-loop regenerative system (downstream of the No. 7 high-pressure heater j 7), the yield is the highest, the steam extraction amount of the low-pressure heater, the deaerator 40 and the high-pressure heater is reduced, or the low-pressure heater, the deaerator 40 and the high-pressure heater are not used for heating at all, and the use of steam extraction is also avoided. If the heating system is used for heating condensed water at the outlet of the low-pressure heater (the downstream of the No. 4 low-pressure heater j4 (the upstream of the deaerator 40), the steam extraction amount of the deaerator 40 and the high-pressure heater is reduced, the extracted steam of the exhaust heat recovery system returns to the steam turbine to continue acting, the power and the heat efficiency of the unit are improved, the comprehensive efficiency is lower than that of a mode for heating the outlet temperature of the high-pressure heater in the mode, automatic control is easy to realize, and the potential safety hazard caused by the fact that the final water supply temperature is over-poor.
The heating system further comprises a heating pipeline d2 with two ends respectively communicated with the heat exchange pipeline 300, and the heat collection and exchange device 51 is arranged on the heating pipeline d 2. In addition, the heating system further includes a bypass pipe d1 having both ends respectively communicated with the heat exchange pipe 300, and the bypass pipe d1 is disposed in parallel with the heating pipe d 2. The bypass pipeline d1 is provided with a first switching valve f 1; two second switching valves f2 are arranged on the heating pipeline d2, and the two second switching valves f2 are respectively positioned at the upstream and the downstream of the heat collecting and exchanging device 51.
The invention also relates to a use method of the nuclear power plant two-loop thermodynamic system, when the linear Fresnel reflection light-gathering system 50 can receive solar radiation energy (for example, in the daytime), the first switching valve f1 is closed, the second switching valve f2 is opened, or the first switching valve f1 and the second switching valve f2 are both opened; when the linear fresnel reflection concentrating system 50 is unable to receive solar radiation energy (e.g., at night), the first switching valve f1 is opened and the second switching valve f2 is closed.
The final feed water temperature control deviation of a nuclear power plant M310 unit commonly used in China is 226 +/-2.5 ℃, the control deviation needs to be switched and used through a bypass pipeline d1 and a heating pipeline d2, and the maximum deviation is always controlled not to exceed 2.5 ℃ under the condition of solar radiation energy change, so that the operation safety of key equipment of the nuclear power plant is guaranteed.
The bypass pipe d1 is used for shunting the flow of the condensed water of the heat collection and heat exchange device 51 during heat exchange, and also controlling the water outlet temperature of the heat exchange pipe 300, so that the feed water discharged from the heating pipe d2 after heat exchange of the heat collection and heat exchange device 51 is prevented from vaporizing by mixing cold water and hot water. In addition, the distance between the final feed water temperature of the nuclear power station and a design value is not more than 2.5 ℃ at most, and the thermal power of a heating thermal system is not more than 17MW at most according to thermal balance calculation. According to a conservative concept in the nuclear power field, 10% of safety allowance is designed, so that the maximum designed thermal power of the heating system does not exceed 15 MW; the thermal power of the heating system is actually determined according to the temperature and the pressure of the condensed water at the outlet of the heater, so that the condensed water is prevented from being vaporized to cause equipment damage.
In conclusion, the invention utilizes the solar energy to heat the nuclear power station feed water, reduces the use of the secondary loop thermodynamic system of the nuclear power station for steam extraction on the premise of not depending on external energy, particularly improves the working quality of the main steam in summer, finally improves the power generation power of the power station, and simultaneously provides a new way for the subsequent optimization of nuclear power safe operation by the application of the solar energy in the nuclear power station.
