[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A waste heat recovery structure for a phase change thermal storage device includes a recovery component 1, and a heat exchange mechanism 2 is fixedly connected inside the recovery component 1.

[0027] The recycling component 1 includes a housing 101, the top of the housing 101 is connected to a first electronic valve body 102, the top of the first electronic valve body 102 is connected to a second electronic valve body 103, the side of the second electronic valve body 103 away from the first electronic valve body 102 is connected to a connecting pipe 104, and the bottom of the housing 101 is connected to a connecting pipe 105.

[0028] In this embodiment: by setting up the recovery component 1, the waste heat can be recycled and reused. By setting up the heat exchange mechanism 2, the liquid can be heated by high-temperature gas. By setting up the box 101, the first electronic valve body 102, the second electronic valve body 103, the connecting pipe 104, and the connecting pipe 105, the box 101 can cover the box shell 205. After the high-temperature gas heats the liquid, it moves to the inside of the box 101 through the connecting pipe 105 and contacts the surface of the box shell 205. Then, the surface of the box shell 205 is kept at a certain temperature by the used high-temperature gas. Then, the user can adjust the second electronic valve body 103 as needed, so that the used high-temperature gas moves to the inside of the filter component 201 through the connecting pipe 104, and is used in conjunction with the unfiltered high-temperature gas. After being filtered again, it moves to the inside of the hollow block 202, thus achieving the circulation effect. The user can also close the second electronic valve body 103 and adjust the first electronic valve body 102 to discharge the used high-temperature gas into the inside of the box 101.

[0029] Specifically, such as Figure 3 As shown, the heat exchange mechanism 2 includes a filter assembly 201. The bottom of the filter assembly 201 is connected to a hollow block 202. The bottom of the hollow block 202 is connected to a plurality of hollow tubes 203. The bottom of the plurality of hollow tubes 203 is connected to a conical hollow frame 204. The bottom of the conical hollow frame 204 is connected to the top of the connecting pipe 105.

[0030] Specifically, such as Figure 3 As shown, a housing 205 is fixedly connected to the surface of the hollow block 202. A water inlet flange 206 is connected to the rear side of the housing 205, and a drain flange 207 is connected to the rear side of the housing 205.

[0031] Specifically, such as Figure 3 As shown, a number of partition plates 208 are fitted on the surface of the hollow tube 203, and the surfaces of the partition plates 208 are fixedly connected to the inner wall of the shell 205.

[0032] In this embodiment: By setting up a filter assembly 201, high-temperature smoke and dust can be filtered. By setting up a hollow block 202, several hollow tubes 203, and a conical hollow frame 204, the filtered smoke and dust can first move through the hollow block 202 to the inside of the several hollow tubes 203, and then move to the inside of the conical hollow frame 204. Then, it can contact the liquid inside the housing 205 through the several hollow tubes 203, thus heating the liquid. By setting up a housing 205, a water inlet flange 206, and a drain flange 207, the user can add liquid into the housing 205 through the water inlet flange 206, and then the liquid can be discharged from the housing 205 through the drain flange 207. By setting up several partition plates 208, the liquid flow rate can be limited, increasing the contact time with the several hollow tubes 203, thereby increasing the heating efficiency.

[0033] Specifically, such as Figure 4 As shown, the filter assembly 201 includes an external flange 2011, the bottom of which is connected to a hollow frame 2012. A pull-out hole 2013 is provided on the left side of the hollow frame 2012, and a filter plate 2014 is snapped into the pull-out hole 2013.

[0034] Specifically, such as Figure 4 As shown, alignment grooves 2015 are provided on the front and rear sides of the inner wall of the pull hole 2013, and alignment blocks 2016 that cooperate with the alignment grooves 2015 are fixedly connected to the front and rear sides of the filter plate 2014.

[0035] In this embodiment: by setting an external flange 2011, a hollow frame 2012, a pull-out hole 2013, and a filter plate 2014, the external flange 2011 can be connected to the equipment that needs to emit high-temperature fumes. Then, the high-temperature gas is guided into the interior of the hollow frame 2012. Then, the filter plate 2014 inside the pull-out hole 2013 adsorbs impurities from the fumes. Then, the filtered fumes move into the interior of the hollow block 202. By setting an alignment groove 2015 and an alignment block 2016, it is easy to make contact between the filter plate 2014 and the pull-out hole 2013, thereby increasing the connectivity between the filter plate 2014 and the hollow frame 2012.

[0036] Specifically, such as Figure 1 As shown, two support frames 3 are fixedly connected to the bottom of the box 101, and anti-slip pads 4 are fixedly connected to the bottom of both support frames 3. The material of both anti-slip pads 4 is silicone.

[0037] Specifically, such as Figure 3 As shown, a frame 5 is fixedly connected to the top of several partition boards 208. A water inlet hole 6 is opened on the surface of the frame 5, and a circular hole 7 is opened on the top of the frame 5.

[0038] In this embodiment: by setting two support frames 3 and two anti-slip pads 4, the box 101 can be easily supported. By setting the frame 5, water inlet 6 and circular hole 7, after the liquid enters the interior of the box 205, it can enter the next layer through the water inlet 6 on the surface of the frame 5 when the water flow is relatively uniform, and enter the next layer through the circular hole 7 when the water source is relatively turbulent, thereby increasing the liquid residence time and thus increasing the heating efficiency.

[0039] Working principle: When high-temperature gas requiring waste heat recovery is generated, such as exhaust gas from industrial boilers, kilns, etc., the high-temperature gas pipeline is connected to the filter assembly 201 through the external flange 2011. The high-temperature gas enters the hollow frame 2012. At this time, the filter plate 2014, which is snapped into the pull-out hole 2013, adsorbs and filters impurities in the high-temperature gas. Then, the filtered high-temperature gas enters the hollow block 202 from the hollow frame 2012, and is then evenly distributed into several hollow tubes 203. The heat exchanger penetrates the housing 205 and exchanges heat with the liquid inside. The housing 205 is pre-filled with the liquid to be heated via the inlet flange 206. As the high-temperature gas flows within the hollow tube 203, it transfers heat to the surrounding liquid through the tube wall, raising the liquid temperature. During this process, the partition plate 208 outside the hollow tube 203 restricts the liquid flow, ensuring a relatively stable flow state within the housing 205 and increasing the contact time between the liquid and the hollow tube 203, thereby improving the heat exchange efficiency. The partition plate 208 has a water inlet 6 and a circular hole 7 on its top frame 5. Depending on the liquid flow rate, the liquid can enter the next layer through the water inlet 6 or the circular hole 7. The high-temperature gas after heating the liquid is collected through the conical hollow frame 204 and then enters the box 101 through the connecting pipe 105. At this time, the box 101 acts as a buffer and heat preservation, allowing the high-temperature gas to fully contact the surface of the box shell 205, and further utilizes the residual heat of the gas to keep the box shell 205 warm, reducing heat loss. According to actual needs, the operator can choose to control the first electronic valve body 102 or the second electronic valve body 103 to determine the destination of the high-temperature gas. If it is necessary to recycle the residual heat, the second electronic valve body 103 is opened, allowing the high-temperature gas in the box 101 to return to the filter assembly 201 through the connecting pipe 104, mix with the newly introduced high-temperature gas, and then carry out the above heat exchange and heat storage process again. This can fully exploit the residual heat value in the high-temperature gas and improve energy utilization efficiency.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
