Embodiment 1

[0039] Such as figure 1 As shown, the concentrating solar water heat storage power generation system includes a heat exchanger 2 with a water inlet and a water outlet, a steam turbine 7, a generator 8, a condenser 9, a cooling tower 10, a feed water pump 11, a circulating water tank 12, a storage Heat tank 4, and solar heat collector 1 for providing heat source for the heat exchanger; the water outlet of the heat exchanger is connected to the heat storage tank through the first three-way pipe 13, and the heat storage tank is connected to the heat storage tank through the second three-way pipe 14 It is connected with the steam turbine, the steam turbine is connected with the generator and the condenser respectively, the condenser is connected with the cooling tower and the feed water pump respectively, the feed water pump is connected with the circulating water tank, and the circulating water tank is also connected with the water outlet of the heat exchanger; the first A heat s...

Embodiment 2

[0043] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that a third three-way pipe 15 is also provided between the first three-way pipe and the main steam valve of the steam turbine; The third three-way pipe is connected.

[0044] Compared with Embodiment 1, this embodiment also has the function of generating electricity in cloudy days, rainy days and nights. The reason: due to cloudy days, nights, and even extreme cold, the air is still radiating heat. Therefore, at any time the solar collectors have part of the thermal energy generated. If there is no heat storage system, this part of the heat energy is not enough to heat the power generation medium to generate steam. Therefore, the traditional concentrated solar power generation system can only generate electricity when there is sufficient sunlight, but cannot generate electricity at other times. This fundamental defect is one of the important reasons why concentrated solar energy c...

Embodiment 3

[0065] Such as image 3 As shown, the difference between the present embodiment and embodiment 2 is that the steam turbine is a double-cylinder steam turbine, which is divided into a high-pressure cylinder of a steam turbine and a low-pressure cylinder of a steam turbine; The solar collector is also provided with a solar reheater 16 with an inlet and an outlet, the inlet of which is connected to the high-pressure cylinder of the steam turbine, and the outlet is connected to the low-pressure cylinder of the steam turbine.

[0066] This embodiment is to solve the problem of cavitation of the blades of the steam turbine caused by the high water content of the blades of the last stage of the steam turbine in the power generation system in the supercritical state. Without special treatment, the steam cannot fully expand in the steam turbine, resulting in a loss of efficiency. Therefore, in order to improve the efficiency of the unit, it is necessary to adopt the method of intermed...

Abstract

The invention discloses a condensation solar energy water heat storage power generation system. The problems that in the prior art, solar energy is wasted mostly and can not be stored and used reasonably are solved. The condensation solar energy water heat storage power generation system comprises a heat exchanger with a water inlet and a water outlet, a turbine, a generator, a condenser, a cooling tower, a feed pump, a circulating water tank, a heat storage tank and a solar collector used for providing a heat source for the heat exchanger. A systemic, complete, reliable and practical solution scheme is provided for condensation solar power generation. The heat storage problem in the condensation solar power generation technology is solved, so that the system is stable, generates power in all weather and sufficiently uses heat energy of solar radiation at night, on rainy days and in all weather.

Description

technical field [0001] The invention relates to a concentrated solar water heat storage power generation system. Background technique [0002] In daily life, the solar energy irradiated on the earth for about 40 minutes is enough for the energy consumption of human beings all over the world for one year, and it is truly inexhaustible and clean energy. Solar power generation is one of the most important ways to utilize solar energy, and has the following characteristics: ① No risk of depletion; ② Absolutely clean (no pollution); ③ Not limited by geographical distribution of resources; ④ Power generation can be done nearby; ⑤ Energy quality High; ⑥ Emotionally easy for users to accept; ⑦ It takes a short time to obtain energy. With the advent of the clean energy revolution, solar power generation has attracted great attention from all over the world. [0003] Solar power generation is divided into two ways: solar photoelectric conversion and thermoelectric conversion. Photo...
