Embodiment Construction

[0027] In order to make this patent, the characteristics and advantages of this patent can be more obvious, and the following is a particular example, with the drawings, the detailed description is as follows:

[0028] The invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] Such as figure 2 As shown, the nuclear power pendulum system based on seawater dilution technology is mainly included in the following sections: Ultrafiltration plant for removing non-soluble impurities is used to preheat the remaining steam of the steam turbine 8 of the nuclear power unit. The heat exchanger 6 for low temperature seawater is used to dilute the seawater, which is used to deterate the salt-depletion of concentrated seawater (consisting of dilaty plants and chlorine plants) for use with natural conditions. And low temperature seawater for cooling the mixed tank 5 and Mingqu 4 from the high temperature seawater from the chlorine pl...

Abstract

The present invention proposes a nuclear power peak regulation system and method based on seawater desalination technology. Multiple chlorine plants in Group B and Group B, and each desalination plant in each group works in parallel; the desalination plants in Group A are connected to the chlorine plants in Group A to form the first group of joint desalination plants; the desalination plants in Group B The plant is connected to the chlorine plant in group B to form the second group of combined desalination plants; the desalination plant and the chlorine plant are powered by nuclear power units, and each desalination plant is powered independently. The peak shaving method makes the nuclear power units run at full capacity during the peak load period, one of the two combined desalination plants is out of operation, and the two sets of combined desalination plants are put into operation at the same time during the off-peak period. Using hydropower cogeneration to meet the requirements of nuclear power units to participate in peak regulation, extend the operating time of nuclear power with base load, increase the minimum operating power of nuclear power units, and then improve the safety and economy of nuclear power operation.

Description

Technical field [0001] The present invention relates to the field of nuclear power operation control and the field of peak, and more particularly to nuclear power peak systems and methods based on seawater desalination techniques. Background technique [0002] The nuclear power petrophotometric system based on seawater dilution technology is generally used in the load low-grain, and a part of the electric energy is used for the production of seawater, and improves the load capacity of the load low valley period, thereby improving nuclear power units. The minimum operating power in the load low valley period can enhance the safety and economy of nuclear power units in the participation of peaks. With the continuous increase in the investment capacity of nuclear power units and the continuous increase in the single-machine capacity of nuclear power units, small-scale seawater duel plants on large-capacity nuclear power units are relatively high and have a greater impact on the natu...
