Description

Technical Field

[0001] The utility model belongs to the field of large-scale inter-seasonal heat storage, and in particular relates to a modular anti-seepage and heat-insulating floating roof system of a large-scale inter-seasonal heat storage tank. Background Art

[0002] The top heat dissipation of large-scale inter-seasonal heat storage bodies accounts for more than 50% of the heat loss of the entire system. Therefore, an efficient and reasonable top insulation system is an important link in improving the efficiency of large-scale inter-seasonal heat storage.

[0003] Commonly used large-scale cross-seasonal water storage top insulation and anti-seepage systems can be divided into fixed and floating types. The fixed top anti-seepage insulation system has a good insulation effect, but it requires a support system and is expensive; the floating anti-seepage insulation system relies on the buoyancy of the water body to support the top anti-seepage insulation components, which is cheaper and easier to commercialize.

[0004] The floating anti-seepage insulation system is divided into two types: integrated and modular. The integrated anti-seepage insulation floating roof has good insulation efficiency, but the installation is time-consuming and labor-intensive, and it is easy to crack during operation and difficult to maintain; the modular anti-seepage insulation floating roof has module joints, so the insulation effect is slightly worse than the integrated floating roof, but it is easy and quick to install, there is no cracking problem during operation, and it is easy to maintain and has a low cost.

[0005] The current modular anti-seepage and thermal insulation systems mostly adopt mortise and tenon joints or pin joints. The mortise and tenon joints have vertical through seams from top to bottom, and the pin joints have many connection components, which makes the construction complicated. Therefore, the modular anti-seepage and thermal insulation floating roof provided by the utility model adopts a "convex-concave groove" connection, which has a simple structure, good thermal insulation effect, and convenient construction and installation. Utility Model Content

[0006] The utility model aims to solve the problem of top insulation of large-scale hot water storage bodies, and is suitable for modular anti-seepage and thermal insulation floating roofs of large-scale open hot water storage bodies, thereby providing a modular anti-seepage and thermal insulation floating roof system for large-scale cross-seasonal hot water storage tanks, which has the characteristics of convenient construction, simple maintenance, and low cost, and provides a new solution for commercial low-carbon heating mode.

[0007] To achieve the above-mentioned purpose of the utility model, the utility model provides a modular anti-seepage and thermal insulation floating roof system for a large-scale cross-seasonal hot water storage tank, comprising a "groove" module, a "convex groove" module, aluminum foil, a high-temperature resistant flexible anti-seepage membrane, and an upper anti-seepage protective membrane. The side of the "groove" module is made with an inwardly concave tenon, the cross-section of the tenon comprises a rectangular straight segment and a trapezoidal segment, and a step is provided at the connection between the rectangular straight segment and the trapezoidal segment; the side of the "convex groove" module is made with an outwardly protruding tenon rod that cooperates with the tenon groove, the cross-section of the tenon rod comprises a rectangular straight segment and a trapezoidal segment, and a step is provided at the connection between the straight segment and the trapezoidal segment. When the tenon rod of the "convex groove" module is inserted into the tenon groove of the "groove" module, it is clamped and fixed by the trapezoidal segment, the bottom and side of the "groove" module and the "convex groove" module are respectively fixed with aluminum foil reflective layers, and turned to the top edge of the module, the high-temperature resistant flexible anti-seepage membrane is fixed on the outside of the aluminum foil reflective layer, and multiple "groove" modules and "convex groove" modules are connected to form a continuous modular thermal insulation layer, and the upper anti-seepage protective membrane is laid on the top of the modular thermal insulation layer.

[0008] Furthermore, the "groove" module and the "convex groove" module both include an intermediate module, an edge sealing module and a special-shaped module, ensuring that they can be smoothly spliced ​​into the shape of the top surface of the pool.

[0009] Furthermore, the aluminum foil reflective layer and the high temperature resistant flexible anti-seepage membrane are both turned over to the top of the module by no less than 100 mm.

[0010] Furthermore, the trapezoidal section of the mortise and tenon cross section is 2-5 cm longer than the rectangular straight line section.

[0011] Furthermore, it also includes exhaust valves, and the modular insulation layer is provided with multiple exhaust valves for exhausting water vapor exceeding the design level.

[0012] Compared with other large-scale cross-seasonal heat storage tanks, the utility model has the following positive effects:

[0013] (1) There are few connecting components, the connection method is simple, and the construction is convenient.

[0014] (2) There are no vertical seams, which increases the thermal insulation effect and improves the heat storage efficiency.

DETAILED DESCRIPTION

[0024] In order to better understand the purpose, structure and function of the utility model, the modular anti-seepage and thermal insulation floating roof system of a large-scale cross-seasonal hot water storage tank of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] like Figure 1 As shown, a modular anti-seepage and thermal insulation floating roof system for a large-scale cross-seasonal hot water storage tank mainly includes: a hot water storage body 1, a tank dam 2, a drainage ditch 3, a "groove" module 4, a "convex groove" module 5, an upper anti-seepage protective membrane 6, a maintenance manhole 7 and an exhaust valve 8.

[0027] like Figure 3 and Figure 5 As shown, the side of the "groove" module 4 is made with an inwardly concave tenon 9, the cross section of which includes a rectangular straight segment and a trapezoidal segment, and a step is provided at the connection between the rectangular straight segment and the trapezoidal segment; the side of the "convex groove" module 5 is made with a tenon rod 10 protruding outward and matching the tenon, the cross section of the tenon rod includes a rectangular straight segment and a trapezoidal segment, and a step is provided at the connection between the straight segment and the trapezoidal segment. When the tenon rod of the "convex groove" module 5 is inserted into the tenon of the "groove" module 4, it is clamped and fixed by the trapezoidal segment. The bottom and side of the "groove" module 4 and the "convex groove" module 5 are wrapped with aluminum foil 11 and a high-temperature resistant anti-seepage membrane 12 and turned to the top edge of the module. The bottom and side of the "groove" module 4 and the "convex groove" module 5 are respectively fixed with an aluminum foil reflective layer 11, and turned to the top edge of the module. The outside of the aluminum foil reflective layer 11 is fixed with a high-temperature resistant flexible anti-seepage membrane 12. Multiple "groove" modules 4 and "convex groove" modules 5 are connected to form a continuous modular insulation layer, and the upper anti-seepage protective membrane 6 is laid on the top of the modular insulation layer.

[0028] The modular insulation layer is provided with a plurality of exhaust valves 8 for discharging water vapor exceeding the design level to ensure the safety of the heat storage system; at the same time, a certain number of inspection manholes 7 are arranged near the dam of the pool according to the size of the water surface.

[0029] An embodiment of the utility model can be completed according to the following steps:

[0030] like Figure 1 As shown, according to the scale of the heat storage system, a water pool of the hot water storage body 1 is designed and excavated, and a water pool dam 2 and a drainage ditch 3 are built. The material of the water pool dam 2 can be excavated as much as possible to save construction cost. The top elevation of the water pool dam 2 on the water body 1 side should be the same as that of the insulation module.

[0031] According to the analysis and calculation results of the heat storage system, determine the type and thickness of the hard insulation material. Generally, the thickness of the insulation material is preferably 200mm-300mm. According to the surface shape and size of the large-scale hot water storage body, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , respectively design the required sizes of the "groove" module 4 and the "convex groove" module 5. It should be noted that the module size should be square, the types of the "groove" module 4 and the "convex groove" module 5 should be few, and there should be different types such as middle modules, edge sealing modules, special-shaped modules, etc., to ensure that they can be smoothly spliced ​​into the shape of the top surface of the pool.

[0032] According to the modules designed in the previous step, select hard insulation materials to process the "groove" module 4 and the "convex groove" module 5. The "groove" module is made with inwardly concave mortises around it, and its cross-section includes a rectangular straight segment and a trapezoidal segment. The "convex groove" module is made with outwardly protruding tenons around it, and its cross-section also includes a rectangular straight segment and a trapezoidal segment. When the tenon of the "convex groove" module is inserted into the mortise of the "groove" module, it can be clamped and fixed by the trapezoidal segment to prevent loosening, while the rectangular straight segment can provide sufficient shear bearing capacity. In general, the two ends of the trapezoidal cross-section should be 2-5cm longer than the rectangular diameter segment to provide sufficient connection strength while ensuring smooth insertion. In order to ensure smooth clamping, the dimensions of the "groove" module and the "convex groove" module are required to be processed strictly according to the design dimensions, and trial assembly should be carried out after processing to ensure that the module "groove" module 4 and the module "convex groove" 5 can be assembled together. Figure 6 It tightens just as smoothly.

[0033] For the finished insulation module, an aluminum foil reflective layer 11 is fixed on the bottom and sides as a heat reflective layer to enhance the insulation effect of the floating roof, and is turned over to the top of the module by no less than 100 mm. After the aluminum foil reflective layer 11 is fixed, a high temperature resistant flexible anti-seepage membrane 12 is fixed on the bottom and sides, and is turned over to the top of the module by no less than 100 mm to isolate moisture, protect the module and provide buoyancy.

[0034] in accordance with Figure 6 The top module layout of the example pool is shown in the figure. The "groove" module 4 and the module "convex groove" 5 are spliced ​​on site. After the splicing is completed, the upper anti-seepage protective membrane 6 is laid on the top to complete the construction.

[0035] Through the above steps, the construction and installation of a modular anti-seepage and thermal insulation floating roof system for a large-scale cross-seasonal hot water storage tank was successfully completed.

[0036] The utility model has the advantages of simple structure, convenient installation, good heat preservation effect, simple later maintenance, outstanding economic benefit, and is particularly suitable for the top heat preservation system of large-scale cross-seasonal hot water storage tanks.

[0037] The above examples illustrate the basic principle, main features and implementation process of the utility model. The examples are only examples of the utility model, not all examples, and cannot be used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes. Under the inspiration of the technical personnel in this field, without departing from the purpose of the invention of the utility model, the structural methods and embodiments similar to the technical solution without creative design should all belong to the protection scope of the utility model.
