[0002] In the preparation process of high-efficiency desulfurizers, many reactions and processing steps generate a large amount of heat. Currently, most preparation systems do not effectively recover and utilize this heat, resulting in a large waste of heat. This not only increases energy consumption costs but may also cause thermal pollution to the surrounding environment.
[0003] Existing heat recovery devices suffer from problems such as low heat recovery efficiency, complex structure, and difficult maintenance. Furthermore, these devices generally use simple heat exchangers with limited heat exchange area, which cannot fully absorb the heat generated during the preparation process. Moreover, these devices often lack precise control and reasonable distribution of heat, and cannot provide appropriate heat according to the actual needs of different stages of the desulfurizing agent preparation system, making it difficult to achieve efficient heat utilization. Therefore, we propose a high-efficiency heat recovery device for desulfurizing agent preparation systems. Utility Model Content

[0024] This utility model provides, for example Figure 1-3 The heat recovery device for a high-efficiency desulfurizer preparation system shown includes a heating furnace 1, a heat exchange tube 2, and a phase change heat storage box 3. The heating furnace 1 is wound with the heat exchange tube 2, and the two ends of the heat exchange tube 2 are respectively provided with a liquid inlet 4 and a liquid outlet 5. The phase change heat storage box 3 is provided on one side of the heating furnace 1. The phase change heat storage box 3 is filled with a composite phase change heat storage material 6. The liquid inlet 4 and the liquid outlet 5 are fixedly connected to the top and bottom of one side of the phase change heat storage box 3, respectively. Multiple branch pipes 7 are fixedly installed on the other side of the phase change heat storage box 3. Electric regulating valves 8 are fixedly installed on the surface of each of the multiple branch pipes 7. One end of the branch pipe 7 is connected to the phase change heat storage box 3, and the other end is connected to the equipment in the desulfurizer preparation system that requires heat, such as a raw material preheating device and a drying device, to achieve efficient heat utilization.
[0025] This utility model discloses a heat recovery device for a high-efficiency desulfurizer preparation system. A motor 9 is fixedly installed on the top of the phase change heat storage box 3. The output end of the motor 9 extends into the interior of the phase change heat storage box 3 and a stirring shaft 10 is fixedly installed thereon. Stirring blades 11 are fixedly installed on the surface of the stirring shaft 10. This device enables the composite phase change heat storage material 6 to be heated evenly during the phase change process, thereby improving the heat storage and heat release efficiency.
[0026] This utility model discloses a heat recovery device for a high-efficiency desulfurizer preparation system. The phase change heat storage box 3 is provided with a heat insulation layer 12 on its surface. The heat insulation layer 12 includes a vacuum insulation board 13 and a polyurethane foam board 14. A temperature sensor 15 and a liquid level sensor 16 are fixedly installed inside the phase change heat storage box 3, which can effectively reduce heat loss. The temperature sensor 15 and the liquid level sensor 16 are used to monitor the temperature inside the box and the liquid level of the heat storage medium in real time.
[0027] This utility model discloses a heat recovery device for a high-efficiency desulfurizing agent preparation system. A controller 17 is fixedly installed on the surface of the phase change heat storage box 3. The controller 17 is electrically connected to a temperature sensor 15, a liquid level sensor 16, multiple electric regulating valves 8 and a motor 9. The controller 17 can automatically adjust the opening of the electric regulating valves 8 according to the information fed back by each sensor, and accurately control the distribution of heat.
[0028] This utility model discloses a heat recovery device for a high-efficiency desulfurizer preparation system. A circulation pump 18 is fixedly installed at the liquid inlet 4 of the heat exchange tube 2. The circulation pump 18 can drive the heat transfer medium in the heat exchange tube 2 to circulate, accelerate the heat transfer speed, and improve the heat collection efficiency.
[0029] This utility model discloses a heat recovery device for a high-efficiency desulfurizer preparation system. The surfaces of the multiple branch pipes 7 are all provided with heat insulation cotton 19, which can reduce heat loss during the transportation process.
[0030] In operation, the heat exchange tube 2 is first encircled around the outer wall of the heating furnace 1. The circulating pump 18 drives the heat transfer medium to flow in from the inlet 4 of the heat exchange tube 2. As it flows through the heat source equipment, it quickly absorbs the heat emitted by the heating furnace 1. The heated heat transfer medium then flows out from the outlet 5, transferring the heat to the phase change heat storage tank 3. Inside the phase change heat storage tank 3, the composite phase change heat storage material 6 absorbs heat and undergoes a phase change, storing the heat. Driven by the motor 9, the stirring shaft 10 and stirring blades 11 of the phase change heat storage tank 3 ensure uniform heating of the composite phase change heat storage material 6, improving heat storage efficiency. Simultaneously, the temperature sensor 15 and the liquid level sensor 16 monitor the temperature and liquid level of the heat storage medium inside the phase change heat storage tank 3 in real time and transmit the signals. The information is fed back to the controller 17. When the raw material preheating device, drying equipment, etc. in the desulfurizing agent preparation system need heat, the controller 17 controls the electric regulating valve 8 on the branch pipe 7 to open and adjust the opening degree according to the temperature requirements of these devices. This allows the heat stored in the phase change heat storage box 3 to be transported to the equipment that needs heat through the branch pipe 7, meeting the operating requirements of the equipment. During the heat transport process, the insulation cotton 19 on the outside of the branch pipe 7 can reduce heat loss and ensure the effective utilization of heat. Under the coordination of the controller 17, the entire heat recovery device realizes efficient collection, storage and precise distribution of heat, effectively improving the energy utilization efficiency of the desulfurizing agent preparation system and reducing production costs.
