Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a yellow phosphorus combustion heat energy recovery device, including a combustion tower 1, a gas supply pipe 2 fixedly connected inside the combustion tower 1, a filter box 3 fixedly connected to the outer wall of the gas supply pipe 2, a filter screen 4 disposed inside the filter box 3, a connecting pipe 5 fixedly connected inside the filter box 3, a blower 6 fixedly connected to the outer wall of the connecting pipe 5, a conveying pipe 7 fixedly connected inside the blower 6, a heating box 8 fixedly connected to the outer wall of the conveying pipe 7, a water outlet pipe 9 fixedly connected inside the heating box 8, and a water supply component disposed on the outer wall of the heating box 8 for providing a water source.

[0024] Specifically, the gas supply pipe 2 is used to transport the high-temperature exhaust gas generated by the combustion of yellow phosphorus inside the combustion tower 1 to the filter box 3. The filter box 3 supports the filter screen 4, which filters the high-temperature exhaust gas to prevent direct use and pollution. The blower 6 is used to draw the exhaust gas inside the filter box 3 into the delivery pipe 7 through the connecting pipe 5. The delivery pipe 7 is used to transport the gas, which can be delivered to the heating box 8 for use. The water outlet pipe 9 is used for drainage.

[0025] Reference Figure 1 and Figure 3 The water supply assembly includes a water tank 10, the outer wall of which is fixedly connected to the outer wall of the heating box 8, a water pump 11 is fixedly connected to the upper surface of the water tank 10, a water supply pipe 12 is fixedly connected to the output end of the water pump 11, and the outer wall of the water supply pipe 12 is fixedly connected to the inside of the heating box 8.

[0026] Specifically, the heating box 8 serves to support the water tank 10. By starting the water pump 11, the water inside the water tank 10 can be pumped into the water supply pipe 12. The water supply pipe 12 serves to transport the water source to the heating box 8 for later use. Since the heating box 8 contains high-temperature exhaust gas, the waste heat can be used to heat the water source.

[0027] Reference Figure 1 and Figure 4 A sealing cover 13 is slidably connected to the inner wall of the combustion tower 1. A pull rod 14 is slidably connected to the inside of the combustion tower 1. A fixing plate 15 is fixedly connected to the outer wall of the pull rod 14. The outer wall of the fixing plate 15 is slidably connected to the inside of the combustion tower 1. One end of a first spring 16 is fixedly connected to the outer wall of the fixing plate 15. The other end of the first spring 16 is fixedly connected to the inside of the combustion tower 1. A locking rod 17 is fixedly connected to the outer wall of the fixing plate 15. The outer wall of the locking rod 17 is slidably connected to the inside of the combustion tower 1. A sliding rod 18 is slidably connected to the outer wall of the locking rod 17. The outer wall of the sliding rod 18 is slidably connected to the inside of the combustion tower 1. A pull piece 19 is fixedly connected to the outer wall of the sliding rod 18. The outer wall of the pull piece 19 is slidably connected to the inside of the combustion tower 1. One end of a second spring 20 is fixedly connected to the outer wall of the pull piece 19. The other end of the second spring 20 is fixedly connected to the inside of the combustion tower 1. A locking post 21 is fixedly connected to the outer wall of the pull piece 19. The outer wall of the locking post 21 is slidably connected to the inside of the combustion tower 1. The outer wall of the locking post 21 is slidably connected to the inside of the sealing cover 13.

[0028] Specifically, the sealing cap 13 seals the combustion tower 1, which in turn supports the pull rod 14 and the fixing plate 15. Pulling the pull rod 14 causes the fixing plate 15 to slide, compressing the first spring 16. The fixing plate 15 then secures the locking rod 17, causing it to slide simultaneously. The locking rod 17 then slides out of the sliding rod 18, releasing its restriction. The pull plate 19 connects the sliding rod 18 and the locking post 21. When the sliding rod 18 is not... When further restricted, the second spring 20 rebounds, causing the locking pin 21 to slide into the combustion tower 1 via the sliding rod 18. Conversely, by releasing the pull rod 14 and pushing the sliding rod 18 in the opposite direction, the locking rod 17 can be locked inside the sliding rod 18, restricting the locking pin 21 and securing it inside the sealing cover 13. This fixes the positions of the combustion tower 1 and the sealing cover 13. Phosphorus pentoxide produced by the combustion of yellow phosphorus reacts with moisture in the air at high temperatures to form phosphoric acid, an acidic substance with strong corrosiveness. Effective sealing prevents the leakage of these corrosive gases and ensures that heat energy is not dissipated to the outside during combustion.

[0029] Working principle: When the device is needed, yellow phosphorus is placed inside combustion tower 1 for combustion, sealing combustion tower 1. Pulling the lever 14 causes the fixing plate 15 to slide, compressing the first spring 16 during the sliding process. Simultaneously, the fixing plate 15 causes the locking rod 17 to slide out of the sliding rod 18. At this point, the sliding rod 18 is no longer restricted by the locking rod 17, releasing the compression on the second spring 20. The second spring 20 then rebounds, pushing the sliding rod 18 and the lever 19 to slide inside combustion tower 1. During the sliding process, the lever 19 causes the locking pin 21 to slide. The sealing cover 13 is placed above combustion tower 1. Pushing the sliding rod 18 and releasing the lever 14 causes the sliding rod 18 to slide the locking pin 21 into the sealing cover 13, locking the locking rod 17 inside the sliding rod 18. The combustion tower 1 is sealed by the sealing cover 13, preventing the leakage of corrosive gases and the heat generated by combustion. The high-temperature gas generated by the combustion of yellow phosphorus inside the combustion tower 1 enters the interior of the filter box 3 through the gas delivery pipe 2 and is filtered through the filter screen 4. The gas is then transported to the interior of the delivery pipe 7 through the connecting pipe 5 by the blower 6, and then to the interior of the heating box 8 through the delivery pipe 7. The water pump 11 is started to transport the water in the water tank 10 to the interior of the heating box 8 for storage through the water delivery pipe 12. At this time, the high-temperature gas can heat the water inside the heating box 8. The heated water can be discharged through the water outlet pipe 9 for use, thereby converting the wasted heat energy into usable heat energy and realizing the effect of waste heat cascade utilization, thus improving the utilization rate of heat energy. This device can not only prevent the leakage of corrosive gases and the heat loss generated by combustion, thus improving the heat recovery efficiency and safety, but also reuse high-temperature waste gas, realizing the effect of waste heat cascade utilization and improving the utilization rate of heat energy.

[0030] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
