Description

Technical Field

[0001] This invention belongs to the field of concentrated solar power generation technology, and particularly relates to a tower-type concentrated solar power pipeline support system layout structure. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Existing solar thermal power plants, with their steam generation systems located between hot and cold molten salt tanks, suffer from several problems: uneven settlement of the molten salt tanks; high project investment due to long molten salt pipelines; and long steam-water pipelines leading to prolonged turbine start-up time and low operational economy. To address these issues, patent application number 2023107459101, entitled "A Π-shaped planar layout structure for a tower-type solar thermal power zone and its salt drainage method," provides a Π-shaped planar layout structure combined with an energy flow diagram of the process flow. This optimizes the arrangement of the main structures in the power zone, thereby shortening the length of the main pipelines, reducing investment in pipeline supports, decreasing turbine start-up time, and improving the operational economy of the solar thermal power plant.

[0004] However, the inventors discovered the following problems with the Π-shaped planar arrangement structure in application number 2023107459101:

[0005] (1) Currently, the thermal storage capacity of solar thermal molten salt energy storage power plants is gradually increasing. When the thermal storage capacity increases to a certain extent, the volume of the thermal storage tank becomes limited. The Π-shaped planar layout structure technology proposed in application number 2023107459101 also adopts the traditional configuration of one hot molten salt tank and one cold molten salt tank, which can no longer meet the needs of large thermal storage capacity. When the number of hot molten salt tanks and cold molten salt tanks increases, their layout in the power area of ​​the solar thermal energy station and the connecting pipe racks need to be designed accordingly, which cannot simultaneously meet the needs of large thermal storage capacity and the stability and economy of turbine operation.

[0006] (2) Since the working temperature of cold molten salt pipeline is about 200-400℃ and the working temperature of hot molten salt pipeline is about 500-600℃, both of which are hot pipelines, and the cold molten salt pump support and hot molten salt pump support in the Π-shaped planar layout structure of application number 2023107459101 are arranged in a horizontal direction, this will cause the cold molten salt pipeline and hot molten salt pipeline to need to make some additional expansion bends on the overall horizontal support, resulting in waste of materials such as pipelines and elbows. Summary of the Invention

[0007] To address the technical problems mentioned above, this invention provides a tower-type solar thermal pipeline support system layout structure, which can shorten the length of the heat collector support by utilizing the length of the first cold molten salt pump support, thereby reducing the engineering investment of the heat collector support; utilize the vertical orientation of the support to arrange vertical bends, thereby absorbing the thermal displacement of the pipeline; and is suitable for the pipeline support layout in the power area of ​​a solar thermal molten salt energy storage power station with two hot molten salt tanks and one cold molten salt tank.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] The first cold molten salt pump bracket is arranged vertically at one end of the first hot molten salt pump bracket to support the first cold molten salt pump and the molten salt pipeline located between the first cold molten salt tank and the first hot molten salt tank.

[0014] The heat collection bracket is located at the end of the first cold molten salt pump bracket and is arranged perpendicular to the first hot molten salt pump bracket, and is used to support the molten salt pipeline located between the first cold molten salt tank and the heat absorption tower.

[0015] The first cold molten salt pump bracket, the heat exchange bracket, and the heat collection bracket are all located on the same side of the first hot molten salt pump bracket.

[0018] The first hot molten salt pump bracket is arranged horizontally to support the first hot molten salt pump and the molten salt pipeline located between the first cold molten salt tank and the first hot molten salt tank;

[0019] The first cold molten salt pump bracket is arranged vertically at one end of the first hot molten salt pump bracket to support the first cold molten salt pump and the molten salt pipeline located between the first cold molten salt tank and the first hot molten salt tank.

[0020] The heat exchange bracket is vertically arranged at the other end of the first hot molten salt pump bracket; the heat exchange bracket is used to support the molten salt pipeline located between the first hot molten salt tank and the steam generation system structure.

[0021] The heat collection bracket is located at the end of the first cold molten salt pump bracket and is arranged perpendicular to the first hot molten salt pump bracket, and is used to support the molten salt pipeline located between the first cold molten salt tank and the heat absorption tower.

[0022] The first cold molten salt pump bracket, heat exchange bracket, and heat collection bracket are all located on the same side of the first hot molten salt pump bracket.

[0023] The second hot molten salt pump bracket is perpendicular to the first hot molten salt pump bracket and is located on the other side of the first hot molten salt pump bracket. The second hot molten salt pump bracket is located at the first end of the first cold molten salt pump bracket and is used to support the molten salt pipeline located between the second hot molten salt pump and the first cold molten salt tank and the second hot molten salt tank.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] (1) In the tower-type solar thermal pipeline support system of the present invention, the first cold molten salt pump support and the first hot molten salt pump support are arranged in a vertical direction, and the heat collection support is arranged at the end of the first cold molten salt pump support and in a vertical direction with the first hot molten salt pump support. Through the above arrangement structure, the length of the heat collection support can be shortened by utilizing the length of the first cold molten salt pump support, thereby reducing the engineering investment of the heat collection support.

[0026] (2) In the tower-type solar thermal pipeline support system of the present invention, the first cold molten salt pump support and the first hot molten salt pump support are arranged in a vertical direction, so that the molten salt pipeline located on the first cold molten salt pump support and the first hot molten salt pump support can cleverly utilize the vertical direction of the support to arrange vertical bends, thereby absorbing the thermal displacement of the pipeline and reducing the length and investment of the expensive hot pipeline.

[0027] (3) The tower-type solar thermal pipeline support system layout structure of the present invention includes a first hot molten salt pump support, a first cold molten salt pump support, a second hot molten salt pump support, a heat exchange support, and a heat collection support. It is suitable for the pipeline support layout of the power area of ​​a solar thermal molten salt energy storage power station with two hot molten salt tanks and one cold molten salt tank. Moreover, the first cold molten salt pump support is arranged perpendicular to the first hot molten salt pump support and is located on one side of the first hot molten salt pump support; the second hot molten salt pump support is perpendicular to the first hot molten salt pump support and is located on the other side of the first hot molten salt pump support. The two hot molten salt tanks and one cold molten salt tank can simultaneously meet the needs of large-scale heat storage capacity, thereby ensuring the stability and economy of the operation of the solar thermal molten salt energy storage power station.

[0028] (4) The present invention sets up a first maintenance road and a second maintenance road between the heat exchange support and the heat collection support, so that the maintenance road is arranged in parallel with the hot molten salt pump support / cold molten salt pump support. This facilitates the maintenance of the molten salt pump, the appearance of the building is neat, the functional zoning is simple, the land utilization rate is high, the operation and maintenance are convenient, the personnel can enter and exit, the equipment can be replaced and the fire safety is guaranteed, and the land acquisition area and land acquisition and leasing costs are reduced.

[0029] (5) The present invention sets the top layer of the heat exchange support to be lower than the bottom layer of the molten salt pump support, so that the molten salt pipeline between the molten salt tank and the steam generation system structure can form a vertical expansion bend to absorb the thermal displacement of the pipeline.

[0030] (6) In this invention, the molten salt pipe on the heat collection support slopes from the heat absorption tower to the molten salt tank. This makes the elevation of the molten salt pipe on the heat collection support higher than the elevation of the molten salt pipe on the molten salt pump support connected to it. This allows the pipes connecting the heat absorption tower and the cold molten salt tank to drain or discharge salt to the cold molten salt tank by gravity, and also allows the pipes connecting the heat absorption tower and the hot molten salt tank to drain or discharge salt to the cold molten salt tank or the hot molten salt tank by gravity.

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0043] Example 1

[0044] according to Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a tower-type solar thermal pipeline support system layout structure, which includes: a first hot molten salt pump support 1, a first cold molten salt pump support 2, a heat exchange support 3, and a heat collection support 4. Figure 1 As can be seen from the schematic diagram of the tower-type solar thermal pipeline support system layout structure, Figure 1 The arrangement structure of the tower-type photothermal pipe support system can be called a卩-shaped arrangement.

[0045] The arrangement structure of the tower-type photothermal pipe support system provided in this embodiment shortens the length of the main pipeline and reduces pipeline resistance.

[0046] In a specific implementation process, the first molten salt pump support 1 is arranged in a horizontal direction, and is used to support the first hot molten salt pump 10 and the molten salt pipeline between the first cold molten salt tank 6 and the first hot molten salt tank 5; the first hot molten salt pump support constitutes the short horizontal line of the卩-shaped pipe support.

[0047] The first cold molten salt pump support 2 is vertically arranged at one end of the first hot molten salt pump support 1, and is used to support the first cold molten salt pump 12 and the molten salt pipeline between the first cold molten salt tank 6 and the first hot molten salt tank 5; the first cold molten salt pump support constitutes the upper half of the left long vertical line of the卩-shaped pipe support.

[0048] The heat exchange support 3 is vertically arranged at the other end of the first hot molten salt pump support 1; the heat exchange support 3 is configured to support the molten salt pipeline located between the first hot molten salt tank 5 and the building / structure 8 of the steam generation system, that is, the hot molten salt pipeline 11 from the first hot molten salt tank to the building / structure of the steam generation system; the heat exchange support constitutes the short vertical line on the right side of the卩-shaped pipe support.

[0049] The heat collection support 4 is arranged at the end of the first cold molten salt pump support 2 and is arranged perpendicular to the first hot molten salt pump support 1, and is used to support the molten salt pipeline located between the first cold molten salt tank 6 and the heat absorption tower 7; the heat collection support 4 constitutes the lower half of the left long vertical line of the卩-shaped pipe support.

[0050] The heat collection support 4 and the first cold molten salt pump support 2 together form the long vertical line of the卩-shaped pipe support.

[0051] Wherein, the first cold molten salt pump support 2, the heat exchange support 3 and the heat collection support 4 are all located on the same side of the first hot molten salt pump support 1.

[0052] According to Figure 2 , a steam work doing building / structure 9 is also arranged adjacent to the steam generation system building / structure 8.

[0053] In one or more embodiments, the first cold molten salt pump support 2 is arranged closely against the first cold molten salt tank, and the first hot molten salt pump support 1 is arranged closely against the first hot molten salt tank.

[0054] In this embodiment, the top layer height of the heat exchange support 3 is lower than the bottom layer height of the first hot molten salt pump support 1, so that the molten salt pipeline between the molten salt tank and the steam generation system building / structure can form an expansion bend in the vertical direction to absorb the thermal displacement of the pipeline.

[0055] Specifically, the medium flow direction of the molten salt pipelines arranged on the I-shaped tube frame is as follows: the molten salt in the first molten salt tank 6 is drawn out by the first molten salt pump 12, and sequentially connected to the absorber located at the top of the heat absorption tower via molten salt pipelines arranged on the first molten salt pump support and the heat collector support. The molten salt absorbs heat in the absorber and becomes hot molten salt. The hot molten salt sequentially connects to the hot molten salt tank via hot molten salt pipelines arranged on the heat collector support, the first molten salt pump support, and the first hot molten salt pump support, and / or according to... The hot molten salt is connected to the cold molten salt tank via hot molten salt pipes arranged on the heat collection support and the first cold molten salt pump support. The hot molten salt in the first hot molten salt tank is drawn out by the first hot molten salt pump and connected to the steam generation system structure via hot molten salt pipes arranged on the heat exchange support. The hot molten salt becomes cold molten salt after exchanging heat with water in the steam generation system structure. The cold molten salt is then connected to the cold molten salt tank via cold molten salt pipes arranged on the heat exchange support, the first hot molten salt pump support and the first cold molten salt pump support.

[0056] In the specific implementation process, the molten salt pipes on the heat collector support slope from the heat absorber tower towards the molten salt tank. That is, the molten salt pipes closer to the heat absorber tower have a higher elevation than those closer to the molten salt tank, so that the lowest point of the molten salt pipes on the heat collector support exists only on the side of the molten salt pipes near the molten salt pump support. This ensures that the elevation of the molten salt pipes on the heat collector support is higher than that on the molten salt pump support connected to it, allowing the pipes connecting the heat absorber tower and the cold molten salt tank to drain or discharge salt to the cold molten salt tank by gravity, and also allowing the pipes connecting the heat absorber tower and the hot molten salt tank to drain or discharge salt to either the cold or hot molten salt tank by gravity.

[0057] In some embodiments, the molten salt pipes on the heat exchange support are desalinated or discharged to a desalination tank 27 located within the steam generation system structure by gravity. This results in the molten salt pipes on the heat collection support having a higher elevation than the molten salt pipes on the connected molten salt pump support, allowing the pipes connecting the heat absorption tower and the cold molten salt tank to be desalinated or discharged to the cold molten salt tank by gravity, or allowing the pipes connecting the heat absorption tower and the hot molten salt tank to be desalinated or discharged to either the cold or hot molten salt tank by gravity.

[0058] exist Figure 2 In the process, the medium flow direction of the molten salt pipeline arranged on the pipe rack also includes: the molten salt in the first molten salt tank is drawn out by the temperature regulating pump, and is connected to the steam generation system structure in sequence through the molten salt pipeline arranged on the first molten salt pump and temperature regulating pump support, the first hot molten salt pump support, and the heat exchange support. After mixing with the hot molten salt, it becomes molten salt after exchanging heat with water in the steam generation system structure.

[0059] It should be noted that when both the molten salt pump and the temperature regulating pump 13 are installed on the molten salt tank, the first molten salt pump support can also be called the first molten salt pump and temperature regulating pump support.

[0060] Figure 2 The system also includes a molten salt pipeline 14 from the temperature regulating pump to the steam generation system structure, a molten salt pipeline 15 from the heat absorption tower to the first molten salt tank, a molten salt pipeline 17 from the steam generation system structure to the first molten salt tank, and a molten salt pipeline 19 from the first molten salt tank to the heat absorption tower.

[0061] Among them, the first cold molten salt pump and temperature regulating pump support refers to the civil engineering support installed to support the first cold molten salt pump and temperature regulating pump, as well as to support the molten salt pipeline located between the first cold molten salt tank and the first hot molten salt tank. Figure 2 According to the overall layout plan, the first cold molten salt pump and the temperature regulating pump support are arranged vertically, forming the upper half of the long vertical line of the shaped pipe rack.

[0062] The first hot molten salt tank is also called the first hot molten salt storage tank, the first cold molten salt tank is also called the first cold molten salt storage tank, and the second hot molten salt tank is also called the second hot molten salt storage tank.

[0063] The first cold molten salt pump bracket adopts a fixed span on the side near the heat collection bracket, such as the fixed span 18 of the first cold molten salt pump bracket; the first hot molten salt pump bracket adopts a fixed span on the side near the first cold molten salt tank, such as the fixed span 16 of the first hot molten salt pump bracket.

[0064] The term "fixed span" refers to a continuous arrangement of multiple rows of reinforced concrete columns and / or steel columns, where every four adjacent columns form a load-bearing unit. Several load-bearing units directly support the load of the molten salt pump, while at least two rows of reinforced concrete columns and / or steel columns connected to these load-bearing units that directly support the molten salt pump do not support the load of the molten salt pump. In this case, the continuous arrangement of at least two rows of reinforced concrete columns and / or steel columns is called a fixed span.

[0065] The advantages of the above technical solution are that, through the fixed span design, on the one hand, it provides civil engineering support for the molten salt pipeline between the cold molten salt tank and the hot molten salt tank, and the molten salt pipeline between the cold molten salt tank and the heat absorption tower; on the other hand, it increases the rigidity of the molten salt pump support and reduces the vibration of the molten salt pump, thereby improving the safety and reliability of the molten salt pump operation.

[0066] exist Figure 3 The heat exchange support cross-section diagram includes the following equipment: steam drum 23, reheater 24, superheater 25, and low-load heater 26.

[0067] according to Figure 6The connecting pipe rack between the heat transfer zone 33 and the heat storage zone 32 crosses the maintenance road 34 between the two zones. The heat transfer zone and the heat storage zone are defined as follows: the heat absorption tower and the steam generation system are designated as the heat transfer zone; the first cold molten salt tank and the first hot molten salt tank are designated as the heat storage zone.

[0068] The connecting pipe rack between the heat transfer zone and the heat storage zone includes heat exchange support and heat collection support.

[0069] Specifically, the first hot molten salt pump support 1 is arranged parallel to the first maintenance road 20. The first maintenance road 20 is arranged perpendicularly to the heat exchange support 3. The first cold molten salt pump support 2 and the heat collection support 4 are both arranged perpendicularly to the second maintenance road 21. The heat collection support 4 is arranged parallel to the third maintenance road 22. The third maintenance road 22 is arranged perpendicularly to the second maintenance road 21, and the third maintenance road 22 is connected to the second maintenance road 21.

[0070] This facilitates the maintenance of molten salt pumps, results in a neat appearance of buildings, simple functional zoning, high land utilization, and convenient operation and maintenance. It also facilitates personnel access, equipment replacement, and fire safety, while reducing the land acquisition area and land acquisition / lease costs.

[0071] Example 2

[0072] according to Figure 4 and Figure 5 This embodiment provides a tower-type solar thermal pipeline support system layout structure, which includes: a first hot molten salt pump support 1, a first cold molten salt pump support 2, a second hot molten salt pump support 28, a heat exchange support 3, and a heat collection support 4.

[0073] The first hot molten salt pump bracket is arranged horizontally to support the first hot molten salt pump and the molten salt pipeline located between the first cold molten salt tank and the first hot molten salt tank.

[0074] The first cold molten salt pump bracket is arranged vertically at one end of the first hot molten salt pump bracket to support the first cold molten salt pump and the molten salt pipeline located between the first cold molten salt tank and the first hot molten salt tank.

[0075] The heat exchange bracket is vertically arranged at the other end of the first hot molten salt pump bracket; the heat exchange bracket is used to support the molten salt pipeline located between the first hot molten salt tank and the steam generation system structure.

[0076] The heat collection bracket is located at the end of the first cold molten salt pump bracket and is arranged perpendicular to the first hot molten salt pump bracket, and is used to support the molten salt pipeline located between the first cold molten salt tank and the heat absorption tower.

[0077] The first cold molten salt pump bracket, heat exchange bracket, and heat collection bracket are all located on the same side of the first hot molten salt pump bracket.

[0078] The second hot molten salt pump bracket is perpendicular to the first hot molten salt pump bracket and is located on the other side of the first hot molten salt pump bracket. The second hot molten salt pump bracket is located at the first end of the first cold molten salt pump bracket and is used to support the molten salt pipeline located between the second hot molten salt pump and the first cold molten salt tank and the second hot molten salt tank.

[0079] In this embodiment, the top layer of the heat exchange support is lower than the bottom layer of the first molten salt pump support, allowing the molten salt pipe between the molten salt tank and the steam generation system structure to form a vertical expansion bend to absorb thermal displacement of the pipe. Figure 5 The system also includes a molten salt pipeline 30 from the second molten salt tank to the steam generation system structure and a molten salt pipeline 31 from the heat absorption tower to the second molten salt tank.

[0080] In the specific implementation process, the molten salt pipes on the heat collector support slope from the heat absorber tower towards the molten salt tank. That is, the molten salt pipes closer to the heat absorber tower have a higher elevation than those closer to the molten salt tank, so that the lowest point of the molten salt pipes on the heat collector support exists only on the side of the molten salt pipes near the molten salt pump support. This ensures that the elevation of the molten salt pipes on the heat collector support is higher than that on the molten salt pump support connected to it, allowing the pipes connecting the heat absorber tower and the cold molten salt tank to drain or discharge salt to the cold molten salt tank by gravity, and also allowing the pipes connecting the heat absorber tower and the hot molten salt tank to drain or discharge salt to either the cold or hot molten salt tank by gravity.

[0081] In some embodiments, the molten salt pipes on the heat exchange support are drained or discharged into a drain tank located within the steam generation system structure by gravity. This results in the molten salt pipes on the heat collection support having a higher elevation than the molten salt pipes on the connected molten salt pump support. Consequently, the pipes connecting the heat absorption tower and the cold molten salt tank can be drained or discharged into the cold molten salt tank by gravity, and the pipes connecting the heat absorption tower and the hot molten salt tank can also be drained or discharged into either the cold or hot molten salt tank by gravity.

[0082] Based on Figure 6 The connecting pipe rack between the heat transfer zone 33 and the heat storage zone 32 crosses the maintenance road 34 between the heat transfer zone and the heat storage zone. The heat transfer zone and the heat storage zone are defined as follows: the heat absorption tower and the steam generation system are designated as the heat transfer zone; the first cold molten salt tank and the first hot molten salt tank are designated as the heat storage zone.

[0083] The connecting pipe rack between the heat transfer zone and the heat storage zone includes heat exchange support and heat collection support.

[0084] Specifically, the first hot molten salt pump support is arranged parallel to the first maintenance road. The first maintenance road is arranged perpendicularly to the heat exchange support. Both the first cold molten salt pump support and the heat collection support are arranged perpendicularly to the second maintenance road. The heat collection support is arranged parallel to the third maintenance road. The third maintenance road is arranged perpendicular to the second maintenance road, and the third maintenance road is connected to the second maintenance road.

[0085] This facilitates the maintenance of molten salt pumps, results in a neat appearance of buildings, simple functional zoning, high land utilization, and convenient operation and maintenance. It also facilitates personnel access, equipment replacement, and fire safety, while reducing the area of ​​land acquisition and the cost of acquiring and leasing land.
