Description

Technical Field

[0001] This utility model patent relates to the field of thermal insulation for large-scale high-temperature equipment, specifically to a thermal insulation support structure for large-scale high-temperature equipment. Background Technology

[0002] The fixing and support structure of the thermal insulation layer for large high-temperature equipment is crucial to the insulation effect and long-term use of the insulation layer. Especially for large equipment with high operating temperatures, the equipment shell has significant radial and axial thermal expansion. The fixing and support structure of the thermal insulation layer must not only provide good support and fixation, but also be able to adapt well to the thermal expansion of the equipment shell to ensure the insulation effect and long-term use of the insulation layer.

[0003] In solar thermal projects, the operating temperature of large molten salt storage tanks for thermal storage is generally between 300℃ and 575℃, depending on the process route adopted. The required heat loss is extremely low, which results in the insulation layer thickness of the tank being generally around 200mm to 500mm. The insulation support structure is required to support the heavy insulation layer and also adapt to the thermal expansion and contraction of the tank.

[0004] Currently, the conventional support structure for the thermal insulation layer of storage tanks uses flat steel or angle steel around the entire ring, with the support rigidly connected to the tank body. This structure is only suitable for storage tanks operating at low temperatures, where the thermal expansion of the tank is negligible. When the operating temperature of the storage tank is high, the tank body expands significantly, and the currently used conventional structure cannot meet the expansion requirements. Utility Model Content

[0005] In order to solve the technical problems existing in the background art, this utility model provides a thermal insulation support structure for large high-temperature equipment, which ensures the thermal insulation effect of large high-temperature equipment and the long-term use of the thermal insulation layer through a novel thermal insulation layer support structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] Insulation support structure for large high-temperature equipment, including:

[0008] Insulation nails are installed on the outside of the casing;

[0009] Insulation nails include:

[0010] The upright beam has one end fixedly connected to the shell.

[0011] A crossbeam is installed at the other end of the vertical beam along the vertical direction of the vertical beam;

[0012] The bending section is located in the middle of the upright beam;

[0013] A support plate is installed on the outside of the crossbeam, and an outer protective layer is installed on the outside of the support plate.

[0014] Furthermore, the support plate is a U-shaped plate, and the crossbeam is located in the groove of the support plate.

[0015] Furthermore, a heat insulation plate is provided between the crossbeam and the support plate, and the heat insulation plate is embedded in the groove of the support plate.

[0016] Furthermore, the crossbeams, support plates, and outer protective layer are connected by bolts.

[0017] Furthermore, the bent section is an arched protrusion perpendicular to the length of the upright beam.

[0018] Furthermore, the uprights, crossbeams, and bending sections are formed by bending them together as a single unit.

[0019] Furthermore, the outer protective layer has a spliced ​​structure, and expansion joints are provided between adjacent outer protective layers.

[0020] The beneficial effects of this utility model are:

[0021] (1) The thermal insulation layer support structure effectively solves the problem of thermal expansion of the tank in the circumferential and axial directions, and can meet the support requirements of the thermal insulation layer of the high temperature storage tank.

[0022] (2) The insulation nail adopts an elastic bending structure design. Its bending part has deformation compensation function and can perform elastic compensation. This allows the insulation nail to not only play a good supporting and fixing role, but also to effectively compensate for the circumferential and axial thermal expansion of the tank under high temperature conditions, and to adapt well to the thermal expansion of the equipment shell.

[0023] (3) A heat insulation board is installed between the support plate and the insulation nail to effectively block heat conduction. In addition, the outer protective layer is connected to the insulation nail through the support plate, which not only improves the mechanical strength of the overall support system, but also ensures the structural stability of the outer protective layer.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 , 2 As shown, the thermal insulation support structure of the large high-temperature equipment includes thermal insulation nails 3. The thermal insulation nails 3 are welded along the circumference and axial direction of the tank body. The thermal insulation nails 3 can absorb the thermal expansion of the tank body. The thermal insulation nails 3 are set on the outside of the shell 4.

[0035] The specific structure of the insulation nail 3 includes a vertical beam 301, one end of which is fixedly connected to the shell 4. A horizontal beam 303 is arranged vertically along the other end of the vertical beam 301. The vertical beam 301 and the horizontal beam 303 are arranged in an L-shape. A bend 302 is located in the middle of the vertical beam 301. A support plate 1 is provided on the outside of the horizontal beam 303, and an outer protective layer 5 is provided on the outside of the support plate 1. The support plate 1 is a U-shaped plate, and the horizontal beam 303 is located in the groove of the support plate 1. The support plate 1 can connect the insulation nails 3 into a whole and is used to fix the outer protective layer 5 of the thermal insulation layer. A heat insulation plate 2 is provided between the horizontal beam 303 and the support plate 1, and the heat insulation plate 2 is embedded in the groove of the support plate 1. The horizontal beam 303, the support plate 1, and the outer protective layer 5 are connected by bolts. The heat insulation plate 2 provided between the support plate 1 and the insulation nail 3 can effectively block heat conduction. Furthermore, the outer protective layer 5 is connected to the insulation nail 3 through the support plate 1, which not only improves the mechanical strength of the overall support system, but also ensures the structural stability of the outer protective layer 5.

[0036] Based on the above technical solutions, the support structure effectively solves the problem of circumferential and axial thermal expansion of the tank, and can meet the support requirements of the thermal insulation layer of high-temperature storage tanks.

[0037] like Figure 3As shown, the bent portion 302 is an arched protrusion perpendicular to the length direction of the upright beam 301. In specific implementations, the bent portion 302 is a vertical protrusion structure formed with the length direction of the upright beam 301 as a reference. This structure can be implemented in two typical forms: one is a continuously smooth transitional arc-shaped curved surface structure, and the other is a ridge structure with clear bending characteristics, i.e., a square structure. It should be noted that the protrusion direction of this structure can be set in multiple directions according to actual installation requirements; it can be arranged along the orthogonal direction of the length direction of the upright beam 301, or adjusted to other specific spatial orientations. In specific implementations, the upright beam 301, the crossbeam 303, and the bent portion 302 are integrally bent and formed.

[0038] Based on the above technical solutions, the insulation nail 3 adopts an elastic bending structure design. Its bending part 302 has a deformation compensation function and can perform elastic compensation. This allows the insulation nail 3 to not only play a good supporting and fixing role, but also to effectively compensate for the circumferential and axial thermal expansion of the tank under high temperature conditions, and to adapt well to the thermal expansion of the equipment shell.

[0039] like Figure 4 , 5 As shown, the outer protective layer 5 is a spliced ​​structure, and expansion joints are provided between adjacent outer protective layers 5, so that there is a certain amount of room for movement between the outer protective layers 5, which can better adapt to the thermal expansion of the equipment shell.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
