Description

Technical Field

[0001] This utility model belongs to the field of solar thermal power generation, and in particular relates to a rotatable heat absorber device. Background Technology

[0002] With the rapid development of my country's solar thermal industry, tower-type concentrating solar collector technology, with its high thermal efficiency and good grid peak-shaving capabilities, is gaining increasingly widespread market application due to its clean and green attributes, as well as its broad active and reactive power regulation and inertia support capabilities. Tower-type solar thermal power generation systems use multiple plane mirrors to concentrate sunlight, which is then reflected onto the collector at the top of the tower via heliostats. This heats the flowing heat transfer fluid inside the collector to nearly 600°C. The high-temperature heat transfer fluid then generates high-temperature, high-pressure steam through a steam generation system, driving a turbine generator to produce electricity.

[0003] The solar collector is the core equipment for converting solar energy into molten salt heat energy, and its performance affects the overall power generation efficiency of a solar thermal power plant. In tower-type solar thermal power plants, especially multi-tower, single-unit projects, the absorber tubes are arranged in a radial, circumferential distribution. This results in low efficiency for the tubes located in areas with less sunlight, leading to high project investment. To avoid these problems, this invention uses a fan-shaped distribution of absorber tubes on a rotating platform, allowing it to rotate and follow the sun's movement. Utility Model Content

Different drawings may result in different positional relationships, therefore they should not be construed as limiting the scope of protection.

[0029] In this utility model, the terms "installation," "connection," "interlocking," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a connection that allows communication, a direct connection, or an indirect connection through an intermediate medium. They can also refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0030] The following is combined Figures 1-10 This invention provides a detailed description of a rotatable heat absorber device.

[0031] This utility model addresses the technical problems in the prior art by proposing a rotatable heat absorber device, such as... Figure 1 As shown, this utility model provides a rotatable heat absorber device, which includes a rotating bracket, a tube screen bracket, and a tube screen. The rotating bracket and the tube screen bracket are connected by a support beam 1 and a support beam 2, and the tube screen bracket and the tube screen are connected by a pin and a hanging pipe.

[0032] Both support beam 1 and support beam 2 mentioned above are made of profiles with a certain strength; the choice of profiles is not specifically limited here. Support beam 2 is mounted on support beam 1, and support beam 1 and support beam 2 are fixedly connected, such as by welding; the specific connection method between support beam 1 and support beam 2 is not specifically limited here.

[0033] like Figure 2 As shown, an upper heat collector box for the absorber is installed at the top of the tube screen, a lower heat collector box for the absorber is installed at the bottom of the tube screen, and several hanging pipes are installed on one side of the tube screen.

[0034] The upper collector box of the receiver collects the high-temperature working fluid from each receiver tube panel and then distributes it to subsequent heat utilization equipment or storage systems through connecting pipes. It acts as a buffer, stabilizing the pressure and flow rate of the working fluid and reducing the impact of changes in solar radiation intensity or system operation fluctuations on downstream equipment.

[0035] The lower heat collector box of the absorber is located at the bottom of the heat absorber tube screen and is connected to the heat absorber tube screen. It receives the heat transfer medium flowing down from the heat absorber tube screen, plays a buffering role, stabilizes the pressure and flow rate of the heat transfer medium, and reduces fluctuations during system operation.

[0036] The aforementioned tube panels are connected to the upper and lower collector boxes of the receiver via bent pipes. During operation of the solar thermal absorption system, the tube panels and collector boxes will experience thermal expansion due to heat absorption. The bent pipes can buffer thermal stress through their own bending deformation, reducing the risk of pipe damage and leakage caused by thermal expansion and contraction, thus improving the reliability and stability of the system. The shape and arrangement of the bent pipes can also affect the flow state of the working fluid. For example, they can create some disturbance when the working fluid enters the collector box, promoting mixing and reducing temperature differences between different tube panels, thereby improving the overall thermal efficiency of the system.

[0037] like Figure 3 As shown, a hanging pipe is installed on one side of the aforementioned tube screen. The tube screen bracket is connected to the tube screen by pins passing through the hanging pipe. The number of pins and hanging pipes is not limited and depends on the specific circumstances. The pin connection method here can be replaced by a bolt fixing connection method.

[0038] like Figure 4 , Figure 5 As shown, the rotating support column is provided with multiple connecting plates 1, the column is connected to the hanger through connecting beam 1, and the column is connected to the base through a rotary reducer.

[0039] The rotating bracket's uprights are fixedly connected to multiple connecting plates 1, with two connecting plates 1 forming a group, and the number of such plates is not specifically limited. The connecting beams 1 are welded to the surface of the uprights, and the upper and lower surfaces of the connecting beams 1 are also welded to the connecting plates 1, increasing the welding area and making the connecting beams 1 and the uprights integral. The number and specific positions of the connecting beams 1 are determined by the specific conditions of the bracket.

[0040] The bracket consists of several horizontal beams, vertical beams and reinforcing beams. The bracket is equipped with several support beams 1. The bottom of the bracket is equipped with an inlet buffer tank bracket and an outlet buffer tank bracket.

[0041] The aforementioned bracket is welded from horizontal beams, vertical beams, and reinforcing beams. It is used to mount the pipe screen support, and its strength meets the relevant standard requirements. Its specific shape is not specifically limited. The bottom of the bracket is equipped with inlet buffer tank supports and outlet buffer tank supports, which are also welded from horizontal beams and vertical beams. Reinforcing beams can be added if necessary, and their specific shapes are determined by the specific shapes of the inlet and outlet buffer tanks.

[0042] The bottom of the rotating bracket is equipped with a spring pipe, which can bend and expand to a certain extent, adapting to different installation environments and spatial layouts. It can also buffer stress caused by temperature changes, pipe vibration, etc., reducing the risk of damage to the pipe system.

[0043] The rotating support is equipped with rollers at its bottom, which can roll on the platform and, in conjunction with a rotary reducer, drive the rotating support to rotate. A track can be installed on the platform to facilitate the rollers' movement. The specific rolling pattern of the rollers is not specifically limited.

[0044] An inlet buffer tank is installed in the inlet buffer tank support, and an outlet buffer tank is installed in the outlet buffer tank support. The outlet buffer tank is connected to the upper heat collector box of the absorber through a molten salt pipe, and the inlet buffer tank is connected to the lower heat collector box of the absorber.

[0045] Inlet and outlet buffer tanks can reduce pressure fluctuations and flow pulsations caused by unstable operation of upstream equipment or changes in fluid flow within the pipeline, providing stable inlet conditions for downstream equipment, preventing damage from sudden pressure changes, and extending equipment lifespan. They can also store fluid to a certain extent; when upstream flow suddenly decreases or downstream demand suddenly increases, the fluid in the buffer tank can be replenished, regulating flow and maintaining stable system operation.

[0046] like Figure 6 As shown, a lower flange is provided at the bottom of the column, which is connected to the upper flange of the rotary reducer, and the lower flange of the rotary reducer is connected to the flange on the platform.

[0047] A reinforcing plate is installed on the lower flange of the column, and a reinforcing plate is installed at the bottom of the flange on the platform. The bottom of the platform can be fixed to the connecting body by bolts. The column is driven to rotate by the rotary reducer.

[0048] like Figure 7 As shown, a connecting plate 2 is provided on the column, and a sliding groove is provided on the connecting plate 2. The column is fixed to the platform by a supporting steel cable. A sliding rod is provided at one end of the supporting steel cable, and the sliding rod slides in cooperation with the sliding groove. An embedded part is provided at the other end of the supporting steel cable. The specific dimensions of the sliding groove are limited according to the specific situation, and the number of supporting steel cables is not specifically limited.

[0049] like Figure 8 , Figure 9 As shown, the top and bottom of the tube screen bracket are respectively provided with protective plate brackets, the protective plate brackets are provided with protective plates, the back of the tube screen bracket is provided with support beam 2, the middle of the tube screen bracket is provided with several crossbeams, and the sides of the tube screen bracket are provided with mounting beams.

[0050] The protective plate bracket consists of several horizontal and vertical beams, with additional reinforcing beams added as needed. Its specific shape is determined by the shape of the protective plate itself. In the connection structure between the tube panel and the collector box, the protective plate plays a protective and auxiliary role. It prevents damage to pipes, bends, and other components in the connection structure from external factors. Some protective plates have thermal insulation properties, reducing heat loss or absorption at the connection points. For high-temperature operating solar collector systems, the thermal insulation protective plate can reduce heat loss from the connecting pipes between the tube panel and the collector box, improving the system's thermal efficiency. Simultaneously, it prevents safety hazards or accelerated equipment aging caused by excessive heat affecting the surrounding environment. The design of the protective plate can guide the flow of water or other liquids. For example, in rainy weather, the shape and tilt angle of the protective plate can direct rainwater in a specific direction, preventing rainwater accumulation at the connection points and reducing corrosion and icing caused by water accumulation, thus protecting the stability and sealing of the connection structure.

[0051] The specific shape and position of the support beam 2 should match that of the support beam 1. The support beam 1 and the support beam 2 are fixedly connected to connect the tube screen bracket and the rotating bracket.

[0052] like Figure 10 As shown, a fixing plate is provided on the front of the tube screen bracket. The fixing plate is connected to the upper mounting plate and the lower mounting plate through the connecting plate 3. A pin is provided between the upper mounting plate and the lower mounting plate.

[0053] The specific shape and quantity of the aforementioned fixing plates are determined by the specific dimensions of the tube panel. The number and position of the pins are matched with the connecting pipes on the tube panel. The specific shape and position of the connecting plate 3 can be set according to the specific requirements of the situation, and its strength should meet the relevant standards.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
