Description

Technical Field

[0001] This utility model relates to the field of thermal energy storage tank technology, specifically to an insulation structure for a thermal energy storage tank. Background Technology

[0002] Thermal energy storage tanks are containers used to store thermal energy, primarily through sensible or latent heat. They are used to transport thermal energy generated as byproducts from large boilers in power plants, waste incineration plants, and other facilities. Utilizing these thermal energy storage tanks for external heating effectively utilizes waste heat and reduces the energy consumption of the user unit in generating its own heat. However, conventional thermal energy storage tanks for transporting thermal energy typically consist of a single insulation layer covered by a steel protective layer. This single insulation layer structure is prone to heat leakage and has poor insulation performance. During road transport, the temperature of the thermal energy storage tank drops rapidly, resulting in significant heat loss and unnecessary waste of thermal energy. Increasing the insulation thickness is feasible, but this is limited by road transport size restrictions, increases insulation costs and the overall weight of the transport tank, and reduces the transported thermal energy medium under weight restrictions, thus lowering the economic efficiency of thermal energy storage transportation. Therefore, designing an insulation structure for thermal energy storage tanks is essential. Utility Model Content

[0003] The purpose of this invention is to provide an insulation structure for a thermal energy storage tank to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a thermal insulation structure for a thermal energy storage tank, comprising an inner container layer, a thermal insulation structure layer, and an outer steel protective layer, wherein the thermal insulation structure layer is disposed on the surface of the inner container layer, and the outer steel protective layer is disposed on the surface of the thermal insulation structure layer.

[0005] The thermal insulation structure layer includes a thermal insulation inner layer and a thermal insulation inner layer arranged from the inside out;

[0006] The thermal insulation inner layer includes a reflective layer one, a reflective layer two, and a reflective layer three arranged sequentially from the inside out. Thermal insulation layer one is bonded between reflective layer one and reflective layer two, and thermal insulation layer two is bonded between reflective layer two and reflective layer three.

[0007] The heat insulation inner layer includes a bubble layer and a reflective layer four bonded together from the inside out, and the bubble layer and the reflective layer three are bonded together.

[0008] In a further embodiment, the first reflective layer, the second reflective layer, the third reflective layer, and the fourth reflective layer are fiberglass aluminum foil cloth.

[0009] In a further embodiment, the bubble layer is a bubble aluminum film blanket.

[0010] In a further embodiment, both the first insulation layer and the second insulation layer are composed of several layers of insulation cotton.

[0011] In a further embodiment, the thickness of the first insulation layer and the second insulation layer is 50 mm.

[0012] In a further embodiment, the thermal insulation structure layer is composed of several horizontal splicing sections and vertical splicing sections, with a horizontal splicing interface formed between adjacent horizontal splicing sections and a vertical splicing interface formed between adjacent vertical splicing sections.

[0013] In a further embodiment, the outer steel protective layer has a thickness of 0.5-0.8 mm.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention changes the traditional single insulation to a multi-layer composite stacked reflective insulation structure consisting of reflective layer one, insulation layer one, reflective layer two, insulation layer two, reflective layer three, bubble layer and reflective layer four. The high-reflectivity fiberglass aluminum foil cloth of reflective layer one, reflective layer two, reflective layer three and reflective layer four effectively reflects heat radiation back to the heat source, reducing losses and improving the insulation effect. The lower thermal conductivity of insulation layer one and insulation layer two achieves better insulation. The vacuum bubbles of the bubble aluminum film blanket effectively isolate heat transfer through conduction or convection, solving the problem of rapid temperature drop and large heat loss in mobile thermal energy storage tanks during road transportation, thus causing unnecessary energy waste and loss. This allows the thermal energy storage tank or pipeline to achieve better insulation performance during use. Attached Figure Description

Detailed Implementation

[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a thermal insulation structure for a thermal energy storage tank, including an inner container layer 1, a thermal insulation structure layer 2, and an outer steel protective layer 3. The thermal insulation structure layer 2 is disposed on the surface of the inner container layer 1, and the outer steel protective layer 3 is disposed on the surface of the thermal insulation structure layer 2. The inner container layer 1 is a steel container tank or pipe, and the outer steel protective layer 3 is a color steel sheet, a stainless steel sheet, or an aluminum alloy sheet.

[0021] The thermal insulation structure layer 2 includes a thermal insulation inner layer and a thermal insulation inner layer arranged from the inside out;

[0022] The inner insulation layer includes a reflective layer 1 21, a reflective layer 23, and a reflective layer 3 25 arranged sequentially from the inside out. Insulation layer 1 22 is bonded between reflective layer 1 21 and reflective layer 23, and insulation layer 24 is bonded between reflective layer 23 and reflective layer 3 25. Insulation layer 1 22 and insulation layer 24 use insulation materials with low thermal conductivity, good pressure resistance, and significant effect on insulation performance, such as rock wool, glass wool, or aerogel. Insulation layer 1 22 and insulation layer 24 are composed of two or more layers of insulation materials, which can be multiple layers of the same insulation material or multiple layers of different insulation materials.

[0023] The inner insulation layer includes a bubble layer 26 and a reflective layer 27 bonded together from the inside out. The bubble layer 26 is bonded to the reflective layer 25. The bubble layer 26 is made of bubble aluminum film blanket, which is a whole bubble layer with a small area and independent space formed by hot pressing a plastic resin film on the surface. By utilizing the vacuum bubbles of the bubble aluminum film blanket, the extremely low thermal conductivity under vacuum conditions makes it difficult for heat to be transferred by conduction or convection, thus effectively isolating heat. The reflective layers 21, 23, 25 and 27 are smooth glass fiber aluminum foil cloth with a high reflectivity aluminum foil reflective layer. The reflectivity of thermal radiation (infrared) can reach 75%-100%. The aluminum foil reduces heat transfer by reflecting thermal radiation. When the aluminum foil is combined with the air layer, it can form a highly efficient thermal resistance barrier, blocking the influence of external temperature on the internal environment.

[0024] In a further embodiment, the thickness of insulation layer 22 and insulation layer 24 is 50 mm.

[0025] The above technical solutions improve the insulation effect of insulation layer 22 and insulation layer 24.

[0026] In a further embodiment, the thermal insulation structure layer 2 is composed of several horizontal splicing sections and vertical splicing sections, with a horizontal splicing interface 4 formed between adjacent horizontal splicing sections and a vertical splicing interface 5 formed between adjacent vertical splicing sections.

[0027] Through the above technical solution, the installation of each layer of the thermal insulation structure layer 2 is facilitated by the horizontal splicing part and the vertical splicing part. During the splicing process, the horizontal splicing interface 4 and the vertical splicing interface 5 of each upper and lower layer are staggered between the reflective layer 1 21, thermal insulation layer 1 22, reflective layer 2 23, thermal insulation layer 2 24, reflective layer 3 25, bubble layer 26 and reflective layer 4 27, which helps to reduce heat loss and achieve better thermal insulation performance.

[0028] In a further embodiment, the outer steel protective layer 3 has a thickness of 0.5-0.8 mm.

[0029] The above technical solution ensures that the outer steel protective layer 3 protects the thermal insulation structure layer 2 while reducing the overall weight of the tank. The outer steel protective layer 3 is fixedly connected to the support part extending from the tank.

[0030] Working Principle: This invention constructs a multi-layered composite stacked reflective insulation structure consisting of reflective layer 21, insulation layer 22, reflective layer 23, insulation layer 24, reflective layer 3 25, bubble layer 26, and reflective layer 4 27. Reflective layers 21, 23, 35, and 27 effectively reflect thermal radiation back to the heat source, reducing losses and improving insulation performance. Insulation layers 22 and 24 provide insulation, while the vacuum bubbles in bubble layer 26 effectively prevent heat transfer via conduction or convection. This results in better insulation performance with the same insulation thickness, solving the problem of rapid temperature drop and significant heat loss during road transport of mobile thermal energy storage tanks, which leads to unnecessary energy waste and loss.

However, the present invention is not limited to the specific details in the above embodiments.
