[0029] Herein, the first direction X, the second direction Y, and the third direction Z are directions that intersect each other.

[0030] The present disclosure provides a main plant structure of a solar power station. Figure 1 , Figure 2 The main plant structure of the solar power station includes a steam turbine plant 1, a deoxygenation plant 2, an evaporation heat exchange plant 3, and an electric control plant 4. The steam turbine plant 1 is provided with a steam turbine generator assembly 5, which is used to generate electricity under the action of steam. The evaporation heat exchange plant 3 is provided with a steam generating assembly 7, which is used to generate steam. The electric control plant 4 is provided with an electric control assembly, which is used to supply power and control the operation of the steam turbine generator assembly 5, the steam generating assembly 7, and the deoxygenation assembly 6. The deoxygenation plant 2 is provided with a deoxygenation assembly 6, which is used to remove oxygen from condensed water, which is condensed from the exhaust steam of the steam turbine generator assembly 5. The steam turbine plant 1, the deoxygenation plant 2, and the evaporation heat exchange plant 3 are sequentially connected along the first direction X, and the electric control plant 4 is respectively connected with the steam turbine plant 1 and the deoxygenation plant 2 along the second direction Y, and the first direction X and the second direction Y intersect.

[0031] In this way, by arranging the steam turbine plant 1, deaerator plant 2, evaporation heat exchange plant 3, and electric control plant 4 in a highly centralized manner, the steam turbine generator assembly 5, deaerator assembly 6, and steam generator assembly 7 are connected through pipelines, and the electric control assembly in the electric control plant 4 is connected to each electrical equipment through cables, which can shorten the length of pipelines and cables between various thermal equipment, reduce the length of outdoor pipelines, and reduce the pressure drop loss of pipelines, thereby reducing system energy consumption and improving operating efficiency and economy. At the same time, the main power generation system thermal equipment (such as steam turbine generator assembly 5, deaerator assembly 6, steam generator assembly 7 and other equipment) is arranged in the main plant, so that each equipment is compactly arranged, the space utilization rate of the main plant is improved, and the convenience of electronic case operation and maintenance is effectively improved, and the construction cost of the power station is simultaneously reduced, and the economy of the power station is improved.

[0032] In one embodiment of the present disclosure, from a top view, the shapes of the steam turbine building 1, the deaerator building 2, the evaporator heat exchange building 3, and the electric control building 4 can all be triangles, rectangles, pentagons, circles, ellipses, or other shapes. Of course, the shapes of the steam turbine building 1, the deaerator building 2, the evaporator heat exchange building 3, and the electric control building 4 can be the same or different.

[0033] In one embodiment of the present disclosure, see Figure 1, from a bird's-eye view, the shapes of the steam turbine building 1, the electric control building 4, the evaporation heat exchange building 3, and the deoxygenation building 2 are all rectangular. The lengths of the steam turbine building 1, the deoxygenation building 2, and the evaporation heat exchange building 3 are equal or approximately equal. The widths of the steam turbine building 1, the electric control building 4, the evaporation heat exchange building 3, and the deoxygenation building 2 decrease in sequence. The length of the electric control building 4 is the sum of the widths of the steam turbine building 1 and the deoxygenation building 2. No wall may be set between the steam turbine building 1 and the deoxygenation building 2, and any two adjacent buildings among the electric control building 4, the evaporation heat exchange building 3, and the deoxygenation building 2 may share a wall. In this way, the compactness and neatness of the steam turbine building 1, the electric control building 4, the evaporation heat exchange building 3, and the deoxygenation building 2 can be improved, which is convenient for reducing the design difficulty and construction cost of the main building.

[0034] In one embodiment of the present disclosure, from a frontal perspective, the electric control building 4, the evaporation heat exchange building 3, and the deoxygenation building 2 all have multi-layer rooms distributed in sequence along the third direction Z. The steam turbine building 1 has one layer of rooms. Specifically, the deoxygenation building 2 has multi-layer deoxygenation rooms 21 distributed in sequence along the third direction Z, so that the deoxygenation component 6 can be more reasonably placed in the deoxygenation building 2; the evaporation heat exchange building 3 has multi-layer evaporation heat exchange rooms 31 distributed in sequence along the third direction Z, so that the steam generation component 7 can be more reasonably placed in the evaporation heat exchange building 3; the electric control building 4 has multi-layer electric control rooms 41 distributed in sequence along the third direction Z, so that the electric control components can be more reasonably placed in the electric control building 4.

In this way, the rooms on different floors of each plant are set at different heights, so that each floor has a space of different heights, which is conducive to placing equipment of corresponding heights. Compared with rooms on each floor with uniform heights, the construction cost can be reduced. It should be noted that the height of the rooms (such as the electric control room 41, the deaerator room 21, the evaporation heat exchange room 31, and the steam turbine plant 1) in this article refers to the distance from the floor of the room to the ground.

The number of feedwater pumps 64 is three, and three feedwater pumps 64 are arranged in the first-layer deaerator room 21. In this way, through four heaters, and the water flows from bottom to top, the water from the condensate pump 14 can be fully heated to facilitate the subsequent deoxygenation treatment of the deaerator 63.

[0043] In one embodiment of the present disclosure, see Figure 3 The first deoxygenation room 21 is provided with a dosing room 211, a low temperature tray room 212 and a high temperature rack room 213.

Among them, there are multiple heliostats, and multiple heliostats are arranged on the ground around the molten salt tower; the molten salt tower has a receiver, and the receiver has molten salt; the molten salt storage tank includes a high-temperature storage tank and a low-temperature storage tank. The heliostat can reflect sunlight onto the receiver of the molten salt tower so that the low-temperature molten salt in the receiver is converted into high-temperature molten salt, and these high-temperature molten salts enter the high-temperature storage tank through a conveying device (such as a pump). The high-temperature molten salt in the high-temperature storage tank converts condensed water into high-pressure steam through the steam generating assembly 7 in the evaporation heat exchange plant 3, so that the pressure cylinder of the steam turbine generator set 52 in the steam turbine plant 1 works to generate electricity. After passing through the steam generating assembly 7, the high-temperature molten salt will become low-temperature molten salt and be stored in the low-temperature storage tank, so as to prepare to enter the receiver and be heated again to high-temperature molten salt.
