Abstract
Description
Technical Field
[0001] This utility model relates to the field of phase change energy storage materials technology, and in particular to a sweating device for high-purity phase change energy storage materials. Background Technology
[0002] Phase change energy storage materials are a class of functional materials that absorb and release a large amount of latent heat through their own changes in state, thereby achieving the storage and release of thermal energy. High-purity phase change energy storage materials usually refer to phase change energy storage materials with a purity of 99.9% or higher. Their impurity content is extremely low, and their performance is significantly different from that of ordinary phase change energy storage materials. High-purity phase change energy storage materials have become key materials in many high-end industries due to their superior performance. However, the purity of the material has a decisive impact on its performance, and traditional sweating equipment is gradually becoming outdated.
[0003] Traditional sweating equipment, when purifying phase change energy storage materials, generates internal heat to form condensate that mixes with impurities. Due to the lack of effective heat recovery, the heat from the condensate is lost. Furthermore, the condensate cannot be reused due to the lack of proper filtration. Moreover, for high-boiling-point and heat-sensitive phase change energy storage materials, distillation may lead to material decomposition and deterioration. Currently, while the market strives to reduce distillation temperature and shorten the high-temperature residence time of materials while meeting separation requirements, and uses short-path distillers to shorten the gas-liquid separation path, heat recovery of the condensate is still not mature enough, resulting in significant heat loss and wasted costs. In addition, the recovered condensate cannot be reused because impurities are not filtered. Utility Model Content

[0008] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, firstly, the high-temperature condensate enters the outer shell along the outlet pipe and flows along the spiral baffle inside the outer shell. At this time, the water pump is started, and the material to be heated enters the inlet pipe through the inlet pipe one into the inlet pipe two, and then enters the spiral tube bundle inside the inner shell, where it flows. At this time, the high-temperature condensate flows along the spiral baffle on the outer wall of the inner shell, while the material to be heated flows inside the inner shell, absorbing the heat of the high-temperature condensate and prolonging the heat exchange time, thus avoiding the waste of heat energy of the high-temperature condensate.
[0022] 2. In this utility model, the recovered condensate flows out from the protective tube on the other side into the filter tube. After passing through the filter screen, since the bottom of the filter tube is connected to the extension tube, large particles of impurities in the condensate enter the extension tube and are adsorbed by the filter element. The remaining condensate flows into the top of the blocking plate in the collection bucket. At this time, the nut can be rotated to make a gap in the sealing sleeve, so that the impurities in the extension tube can be discharged into the bottom of the blocking plate in the collection bucket.

A perforated plate 17 is fixedly connected in the internal space of the inner barrel 15.

[0037] Specifically, the outer wall of the water outlet pipe 4 is connected to the outer barrel 13 on the left side. The top of the outer barrel 13 is fixed with a sealing ring 14 to ensure a seal and prevent temperature loss. The bottom of the sealing ring 14 is connected to the inner barrel 15.

The inner barrel 15 has a perforated plate 17 inside, so that impurities flow out along the holes during the heating process.

[0038] Please see the appendix Figure 1 - Appendix Figure 3 The inner wall of the outer barrel 13 is connected to multiple annular sleeves 19 by a sturdy fixing method. These annular sleeves 19 are adjacent to each other, and each of them is connected to an infrared lamp sleeve 20 by a reliable fixing method. Each lamp sleeve has a tungsten wire 21 firmly fixed inside to ensure that its heating function works normally. An annular groove 22 is opened at the bottom of the inner wall of the outer barrel 13, so that the impurities and condensate in the inner barrel 15 can flow in the annular groove 22. The top of the outer wall of the collection barrel 202 shown in the figure is connected to a second door 24 by a sturdy fixing method for easy operation. The top of the outer wall of the storage box 6 is also connected to a first door 23 by a sturdy fixing method for easy opening and closing operation by the user during use.
[0039] Specifically, the inner wall of the outer barrel 13 is connected to multiple adjacent annular sleeves 19, with infrared lamp sleeves 20 fixed between them. Tungsten wires 21 are inside for heating. An annular groove 22 is opened at the bottom of the inner wall of the outer barrel 13 to facilitate the flow of impurities and condensate. The top of the outer wall of the collection barrel 202 is connected to a second door 24, and the top of the outer wall of the storage box 6 is connected to a first door 23 for easy operation.
[0040] Working principle: Due to the sweating effect, high-temperature condensate is generated in the inner tank 15. The high-temperature condensate then flows into the annular groove 22 and then into the outlet pipe 4. At this time, the high-temperature condensate flows into the protective pipe 3 through the outlet pipe 4, and then into the outer shell 1 through the perforated plate 8 on the protective pipe 3. It flows along the spiral baffle 12 inside the outer shell 1. In order to avoid the heat dissipation of the high-temperature condensate, the water pump 7 in the storage tank 6 can be started. The liquid that needs to be heated by the water pump 7 is transported to the inlet pipe 9 through the inlet pipe 5. Then, it enters the inner shell 10 through the inlet pipe 9 and flows along the spiral tube bundle 11 inside the inner shell 10. At this time, the high-temperature condensate flows closely to the inner shell 10 along the spiral baffle 12, while the material that needs to be heated flows along the spiral tube bundle 11 inside the inner shell 10, which prolongs its heating time. At the same time, the two flow together to reduce the boundary layer thickness, thereby reducing the thermal resistance and improving the heat recovery efficiency. This also avoids the waste of a lot of heat energy caused by the direct discharge of high-temperature condensate.
[0041] When the recovered high-temperature condensate flows into the filter pipe 201 from the outlet pipe 4 on the right protective pipe 3, it first passes through the filter screen 204 inside the filter pipe 201 to intercept and filter some impurities. Since the filter screen 204 is connected to the extension pipe 205, and the extension pipe 205 is tilted, large particles of impurities in the condensate flow into the extension pipe 205 due to gravity. They are then adsorbed by the filter element 206 inside the extension pipe 205. At this time, the filtered condensate flows into the collection tank 202. The impurities in the extension pipe 205 can be discharged by rotating the nut 208 to create a gap in the sealing sleeve 207 and flow into the collection tank 202. Since the upper and lower layers of the collection tank 202 are separated by the blocking plate 203, the filtered condensate and impurities are prevented from mixing together again. This effectively removes impurities and allows the filtered condensate to be reused, saving costs.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
