Description

Technical Field

[0001] This invention belongs to the field of heat storage box technology, and specifically relates to a high-efficiency heat storage box. Background Technology

[0002] During the emission process of boiler flue gas, the waste heat in the flue gas is also emitted accordingly, which leads to the waste of the waste heat in the boiler flue gas. In order to solve this problem, a heat storage box applied to the boiler flue gas emission pipe has appeared on the market. In practical use, this heat storage box can transfer waste heat from boiler flue gas to the inside of the heat storage medium through pipes. The heat storage medium then conducts this heat to the inside of the box, thus realizing the utilization of waste heat from the flue gas. While this type of heat storage box can indeed achieve efficient utilization of waste heat from flue gas in actual use, it still has some shortcomings: Although the pipes in the heat storage box can conduct waste heat from the flue gas to the heat storage medium, the internal structure of the heat storage box is not designed for efficient heat conduction. The heat storage medium inside the box is usually a fixed liquid or solid structure, which means that the heat conducted by the heat storage medium to objects inside the box is localized. When the heat in the conduction area reaches saturation, the heat storage medium can no longer quickly conduct heat to the objects, causing more heat to enter the next conduction area. When the heat in multiple conduction areas reaches saturation, the waste heat in the flue gas cannot be efficiently utilized, resulting in waste. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency heat storage box.

[0004] To achieve the above objectives, the present invention provides a high-efficiency heat storage box, including a shell structure, in which a first storage box and a second storage box are embedded. An upper shell is fixedly connected to the upper part of the shell structure, and a bottom shell is fixedly connected to the lower part of the shell structure. A heat exchange tube is wound around the first storage box, and a winding pipe is wound around the second storage box. A guide pipe is fixed between the heat exchange tube and the winding pipe. The heat exchange tube includes heat exchange bars fixedly connected inside the heat exchange tube. The heat exchange bars can divide the inner cavity of the heat exchange tube into a medium channel and a flue. The inner cavity of the medium channel is connected to the inner cavity of the guide pipe and the winding pipe through a flow guide pipe.

[0005] In the above technical solution, the upper end of the heat exchange tube is fixedly connected to a flue pipe, and the lower end of the heat exchange tube is fixedly connected to a connecting pipe. The inner cavities of the flue pipe and the connecting pipe are connected to the inner cavity of the flue. At the same time, the end of the flue pipe and the connecting pipe away from the flue penetrates the shell structure.

[0006] In the above technical solution, a pump is further connected to one end of the medium channel away from the guide pipe, and a collection bucket is connected to the receiving end of the pump. The receiving end of the collection bucket is connected to the discharge end of the bypass pipe, and the pump and the collection bucket are installed inside the shell structure.

[0007] In the above technical solution, the shell structure is further provided with a first mounting cavity and a second mounting cavity. The first storage box and the heat exchange tube are installed inside the first mounting cavity, and the second storage box and the winding tube are installed inside the second mounting cavity.

[0008] In the above technical solution, the shell structure is further provided with a hollow cavity, and the upper shell is provided with a storage opening above the first storage box and the second storage box. A sealing cover is rotatably connected to the upper shell near the storage opening.

[0009] In the above technical solution, further, the inner diameter of the winding pipe is smaller than the inner diameter of the medium channel, both the winding pipe and the heat exchange tube are threaded tubular structures, and the pitch of the winding pipe is smaller than the pitch of the heat exchange tube.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. In actual use, the water inside the medium channel of this heat storage box can continuously absorb heat from the flue gas through the heat exchange strips, which can realize the efficient utilization of heat in the flue gas and avoid the flue gas containing too much residual heat.

[0011] 2. When the water inside the medium channel absorbs the waste heat in the flue gas, the water that has absorbed the waste heat can be transferred to the inside of the second storage tank through the bypass pipe. This allows the second storage tank to work with the first storage tank to transfer heat to objects with different heating methods, thus improving the application scenarios of the heat storage tank.

[0014] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Although the pipes in the heat storage box can conduct waste heat from the flue gas to the heat storage medium, the internal structure of the heat storage box is not designed with good heat conduction. The heat storage medium inside the heat storage box is usually a fixed liquid or solid structure. This results in the heat storage medium conducting heat to objects inside the box in a localized manner. When the heat in the conduction area reaches saturation, the heat storage medium is not good at quickly conducting heat to objects. This causes more heat to enter the next conduction area. When the heat in multiple conduction areas reaches saturation, the waste heat in the flue gas cannot be efficiently utilized, resulting in waste of waste heat in the flue gas. To solve the above problems, the following structure is proposed.

[0016] like Figures 1-4 The high-efficiency heat storage box shown includes a shell structure 1, a first storage box 4 and a second storage box 5 embedded inside the shell structure 1, an upper shell 2 fixedly connected to the upper part of the shell structure 1, a bottom shell 12 fixedly connected to the lower part of the shell structure 1, a heat exchange tube 7 wound around the first storage box 4, a winding tube 9 wound around the second storage box 5, and a guide tube 8 fixed between the heat exchange tube 7 and the winding tube 9. In actual use, the first storage box 4 and the second storage box 5 can store the objects to be stored. Then, the heat exchange pipe 7 can transfer the residual heat in the flue gas to the inside of the first storage box 4, and the winding pipe 9 can transfer the residual heat in the flue gas to the inside of the second storage box 5. This can realize the rapid storage of the residual heat in the flue gas by the objects to be heated.

[0017] The heat exchange tube 7 includes a heat exchange strip 75 fixedly connected inside the heat exchange tube 7. The heat exchange strip 75 can divide the inner cavity of the heat exchange tube 7 into a medium channel 73 and a flue 74. The inner cavity of the medium channel 73 is connected to the inner cavity of the guide pipe 8 and the winding pipe 9. Example 2: Please refer to Figure 2-3As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, the heat exchange bar 75 in this embodiment can quickly transfer the preheating in the flue gas to the water inside the medium channel 73, thereby realizing the uninterrupted transfer of heat from the flue gas to the inside of the medium channel 73.

[0018] The heat exchange bar 75 is preferably made of a material with good thermal conductivity. When the flue gas flows inside the flue 74, the residual heat in the flue gas can be transferred through the heat exchange bar 75 to the medium inside the medium channel 73. At this time, the heat-conducting medium inside the medium channel 73 can quickly absorb the heat in the flue gas, thereby realizing the rapid transfer of the heat in the flue gas to the first storage box 4.

[0019] The upper end of the heat exchange tube 7 is fixedly connected to the flue pipe 71, and the lower end of the heat exchange tube 7 is fixedly connected to the connecting pipe 72. The inner cavities of the flue pipe 71 and the connecting pipe 72 are connected to the inner cavity of the flue 74. At the same time, the end of the flue pipe 71 and the connecting pipe 72 away from the flue 74 penetrates the shell structure 1. Workers can connect the exhaust end of the flue pipe 71 to the flue gas collection structure, and the collection end of the connecting pipe 72 to the flue gas conveying structure. This allows the flue gas in the boiler to enter the interior of the flue 74 through the connecting pipe 72, and then the flue gas inside the flue 74 enters the interior of the flue gas collection structure through the exhaust pipe 71.

[0020] The end of the medium channel 73 away from the guide pipe 8 is connected to the pump 10, the receiving end of the pump 10 is connected to the collection tank 11, the receiving end of the collection tank 11 is connected to the discharge end of the bypass pipe 9, and the pump 10 and the collection tank 11 are installed inside the shell structure 1. In actual use, water can be injected into the inside of the medium channel 73. When flue gas is transported inside the flue 74, the heat generated by the flue gas can be transferred to the water inside the medium channel 73 through the heat exchange bar 75. This can achieve uninterrupted transfer of heat from the flue gas to the inside of the medium channel 73. Subsequently, the water that absorbs the heat can enter the inside of the winding pipe 9. Since the discharge end of the bypass pipe 9 is connected to the collection tank 11, and the pump 10 connected to the collection tank 11 is connected to the medium channel 73, the water that releases heat can be pumped back into the medium channel 73 through the pump 10, thereby realizing the recycling of the water.

[0021] The shell structure 1 has a first mounting cavity 13 and a second mounting cavity 14 inside. The first storage box 4 and the heat exchange tube 7 are installed inside the first mounting cavity 13, and the second storage box 5 and the winding tube 9 are installed inside the second mounting cavity 14. Water can also be injected into the first mounting cavity 13 and the second mounting cavity 14. When the heat generated by the flue gas is dissipated into the first mounting cavity 13 and the second mounting cavity 14, the water can absorb the heat dissipated by the flue gas, thereby achieving a heat preservation effect inside the first mounting cavity 13 and the second mounting cavity 14.

[0022] The shell structure 1 is also provided with a hollow cavity 15. The upper shell 2 is provided with a storage opening 6 above the first storage box 4 and the second storage box 5. A sealing cover 3 is rotatably connected to the upper shell 2 near the storage opening 6. The sealing cover 3 can seal the storage opening 6 under normal conditions, which can prevent external objects from entering the interior of the first storage box 4 and the second storage box 5 through the storage opening 6. Example 3: Please refer to Figure 2-3 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, the bypass pipe 9 in this embodiment can uniformly transfer the heat in the water to the interior of the second storage tank 5.

[0023] The inner diameter of the connecting pipe 9 is smaller than the inner diameter of the medium channel 73. Both the connecting pipe 9 and the heat exchange tube 7 are threaded tubular structures, and the pitch of the connecting pipe 9 is smaller than the pitch of the heat exchange tube 7. Setting the inner diameter of the winding pipe 9 to be smaller than the inner diameter of the medium channel 73, and setting the pitch of the winding pipe 9 to be smaller than the pitch of the heat exchange tube 7, can facilitate the rapid transfer of heat from the liquid inside the medium channel 73 to the second storage tank 5.

[0024] Working principle: In actual use, the operator can place the object to be stored in the heat storage box 4 and the second storage box 5 through the storage port 6. Then, the operator can connect the exhaust end of the flue pipe 71 to the flue gas collection structure and the collection end of the connecting pipe 72 to the flue gas conveying structure. This allows the flue gas in the boiler to enter the flue 74 through the connecting pipe 72. Subsequently, the flue gas inside the flue 74 enters the flue gas collection structure through the exhaust pipe 71. Water can also be injected into the first mounting cavity 13 and the second mounting cavity 14. When the heat generated by the flue gas is dissipated into the first mounting cavity 13 and the second mounting cavity 14, the water can absorb the heat dissipated by the flue gas, thereby achieving a heat preservation effect inside the first mounting cavity 13 and the second mounting cavity 14. In actual use, water can be injected into the inside of the medium channel 73. When flue gas is transported inside the flue 74, the heat generated by the flue gas can be transferred to the water inside the medium channel 73 through the heat exchange bar 75. This can achieve uninterrupted transfer of heat from the flue gas to the inside of the medium channel 73. Subsequently, the water that absorbs the heat can enter the inside of the winding pipe 9. Setting the inner diameter of the coiled pipe 9 to be smaller than the inner diameter of the medium channel 73, and setting the pitch of the coiled pipe 9 to be smaller than the pitch of the heat exchange tube 7, can facilitate the rapid transfer of heat from the liquid inside the medium channel 73 to the second storage tank 5. Since the coiled pipe 9 is in direct contact with the second storage tank 5, the heat on the second storage tank 5 can be greater than the heat on the first storage tank 4. In actual use, the operator can place objects that need to be heated quickly inside the second storage tank 5 and objects that need to be heated slowly inside the first storage tank 4. Since the discharge end of the bypass pipe 9 is connected to the collection tank 11, and the pump 10 connected to the collection tank 11 is connected to the medium channel 73, the water that releases heat can be pumped back into the medium channel 73 through the pump 10, thereby realizing the recycling of the water.
