Description

Technical Field

[0001] This utility model belongs to the technical field of tower molten salt power generation and heat collection system, and in particular relates to a heat insulation support for a high-temperature container of a tower molten salt power generation and heat collection system. Background Technology

[0002] The high-temperature container in a tower-type molten salt power generation system operates at temperatures typically above 550°C, requiring support on a steel frame. Such high temperatures, transmitted through the container supports to the steel frame, can lead to excessively high local temperatures, increased local thermal stress, and a reduction in the allowable stress of the frame steel, compromising the frame's safety. Existing methods significantly raise the supports of the high-temperature container to ensure the temperature transmitted to the steel frame remains within acceptable limits. However, increasing the support height requires more installation space and reduces the container's stability, especially under dynamic loads such as seismic forces, necessitating more metal material to ensure container safety. Therefore, a heat-insulating support suitable for the high-temperature container in a tower-type molten salt power generation system needs to be designed. Utility Model Content

[0003] In view of this, to address the problem of high operating temperatures in the high-temperature container of a tower-type molten salt power generation system, which leads to increased local thermal stress and reduced allowable stress in the steel frame due to heat conduction through the container support to the steel structure frame, this invention proposes a heat-insulating support for the high-temperature container of a tower-type molten salt power generation system. By adding a heat dissipation device between the high-temperature container and the supporting frame, the temperature transferred to the steel structure frame is ensured to remain within the allowable range. The heat dissipation device uses corrugated or Z-shaped support plates to increase the convective heat transfer coefficient when air flows over the support. Simultaneously, heat dissipation fins are installed on the support plates to increase the heat dissipation area. Thus, only a slight increase in the height of the support is needed to achieve the required heat dissipation effect, ensuring that the heat transferred to the steel structure frame remains within its tolerance range. Furthermore, using the same metal materials, corrugated or Z-shaped support plates offer better bending resistance and support strength than ordinary flat plates, eliminating the need for the inclined support plates of traditional supports.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating support for a high-temperature container of a tower-type molten salt power generation heat collection system, comprising a support device and a heat-insulating device, wherein the support device and the heat-insulating device are fixedly connected.

The concave surface of the mounting plate is fixedly connected to the external high-temperature container, and the convex surface is fixedly connected to the support plate. The support plate is vertically arranged and its bottom surface is fixedly connected to the base plate.

[0006] The heat insulation device includes a top plate, a bottom plate, and multiple support plates. The top plate and bottom plate are parallel to each other, and the multiple support plates are vertically fixed between the top plate and bottom plate. The top plate is fixedly connected to the bottom plate of the support device, and the bottom plate is fixedly connected to the external container support frame. Multiple layers of heat dissipation fins are fixedly installed on the support plates.

[0007] Furthermore, both the top plate and the bottom plate of the heat insulation device are provided with through holes, and the top plate and the bottom plate of the heat insulation device are fixed together by bolts passing through the through holes and then assembled with nuts.

[0008] Furthermore, the cross-section of the second support plate is wavy.

[0009] Furthermore, the cross-section of the second support plate is a continuous Z-shape.

[0010] Furthermore, the heat dissipation fins are flat rectangular plates.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0033] High-temperature containers come in two types: vertical and horizontal. For these two different types of high-temperature containers, the heat-insulating support for the high-temperature container in a tower-type molten salt power generation system described in this invention has different structures.

[0034] I. Specific Implementation Method 1: When this utility model is used in a vertical high-temperature container, see [link to implementation method]. Figure 1 , Figure 2 , Figure 5-10 This embodiment describes a heat-insulating support for a high-temperature container in a tower-type molten salt power generation system, comprising a support device 1 and a heat-insulating device 2, wherein the support device 1 and the heat-insulating device 2 are fixedly connected.

[0035] The support device 1 includes a mounting plate 11, at least two support plates 12 and a base plate 13. The mounting plate 11 is arc-shaped to fit the external high-temperature container. The concave surface of the mounting plate 11 is fixedly connected to the external high-temperature container, and the convex surface is fixedly connected to the side of the support plate 12. The support plate 12 is vertically arranged, and its bottom surface is fixedly connected to the base plate 13.

[0036] The heat insulation device 2 includes a top plate 21, a bottom plate 22, and multiple support plates 23. The top plate 21 and the bottom plate 22 are parallel to each other, and the multiple support plates 23 are vertically fixed between the top plate 21 and the bottom plate 22. The top plate 21 is fixedly connected to the bottom plate 13 of the support device 1, and the bottom plate 22 is fixedly connected to the external container support frame. Multiple layers of heat dissipation fins 24 are fixedly installed on the support plates 23. Multiple layers of heat dissipation fins 24 are fixedly installed on each support plate 23, and the heat dissipation fins 24 between adjacent support plates 23 do not interfere with each other.

[0037] Both the top plate 21 and the bottom plate 13 of the heat insulation device are provided with through holes. The top plate 21 and the bottom plate 13 of the heat insulation device are fixed by bolts passing through the through holes and then being assembled with nuts.

[0038] It also includes a top plate 14 of the support device, wherein the side of the support plate 12 is fixedly connected to the convex surface of the mounting plate 11, and the top surface is fixedly connected to the top plate 14 of the support device. The mounting plate 11 is vertically arranged, and the convex surface of the mounting plate 11 is fixedly connected to the top plate 14 of the support device.

[0039] When the high-temperature container is vertical, this utility model is installed on the side wall of the container, located on the side of the container. At this time, the mounting plate 11 is set vertically, and the support plate 12 is in the shape of a right trapezoid. The convex surface of the mounting plate 11 is fixedly connected to the side where the right angle of the support plate 12 is located. The top of the support device top plate 14 is fixedly attached to the top of the support device top plate 14. At the same time, the support device top plate 14 is also fixedly connected to the convex surface of the mounting plate 11, which enhances the stability of the connection between the high-temperature container and the heat insulation support described in this utility model.

[0040] The cross-section of the support plate 23 is wavy.

[0041] The cross-section of the second support plate 23 is a continuous Z-shape. The wavy or continuous Z-shaped cross-section of the second support plate 23 increases the area for heat transfer with air, improving heat dissipation efficiency, while also having better bending resistance and support strength, eliminating the need for the inclined support plate of traditional supports.

[0042] The heat dissipation fins 24 are flat rectangular plates.

[0043] The heat dissipation fins 24 are zigzag corrugated plates, which can further increase the heat dissipation area, improve heat dissipation efficiency, reduce the overall size of the device, reduce material consumption, and lower manufacturing costs.

[0044] Depending on the size and weight of the high-temperature container, the support plate 23 of the heat insulation support can be wavy, Z-shaped, or other shaped. The heat dissipation fins 24 include, but are not limited to, straight rectangular plates and zigzag corrugated plates. The size and number of heat dissipation fins can vary depending on the structural differences of the high-temperature container and the temperature difference between the container and the steel structure.

[0045] II. Specific Implementation Method Two: This specific implementation method is an alternative to the heat insulation support for the high-temperature vessel of the tower-type molten salt power generation heat collection system described in Specific Implementation Method One. When used for horizontal high-temperature vessels, see [link to relevant documentation]. Figure 3-10 This embodiment is described below. In this embodiment, the mounting plate 11 is horizontally positioned, and its convex surface is fixedly connected to the top surface of the support plate 12. This embodiment also includes a third support plate 15, which is vertically positioned and fixedly connected to one side of the support plate 12. The top surface of the third support plate 15 is fixedly connected to the convex surface of the mounting plate 11, and its bottom surface is fixedly connected to the base plate 13.

[0046] When the high-temperature container is horizontal, this utility model is installed on the side wall of the container, located below the container. At this time, the mounting plate 11 is set horizontally, and the support plate 12 consists of multiple rectangular plates of different lengths that are fixed vertically. The top surface of the support plate 12 is fixedly connected to the convex surface of the mounting plate 11 to bear the gravity load of the high-temperature container. Support plates 3 15 are added to one or both sides of the support plate 12 and fixed vertically to form a rib structure to enhance the overall structural support strength. The top surface of the support plate 3 15 is also fixedly connected to the convex surface of the mounting plate 11 to share the gravity load of the high-temperature container.

The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification.
