Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a heating device for utilizing waste heat from coal combustion, including a heating component 101, a regulating component 201 and a flue gas duct 30;

[0025] The heating assembly 101 includes a waste heat recovery device 10, a temperature difference generator 11, a battery 12, a water pump 13, a first tube body 14, a heat sink 15, a second tube body 16, an exhaust pipe 17, a water inlet pipe 18 and a sewage pipe 19;

[0026] The inner wall of the waste heat recovery device 10 is installed on the outer wall of the flue gas duct 30, the outer wall of the temperature difference generator 11 is installed on the outer wall of the waste heat recovery device 10, the bottom of the battery 12 is installed on the outer wall of the waste heat recovery device 10, and the outer wall of the water pump 13 is installed on the outer wall of the waste heat recovery device 10 through a mounting frame. The input end of the water pump 13 is connected to the interior of the waste heat recovery device 10, and the output end of the water pump 13 is connected to one end of the first pipe body 14.

[0027] In one embodiment, one end of the first tube body 14 is connected to the water inlet end of the heat sink 15, the water outlet end of the heat sink 15 is connected to one end of the second tube body 16, and the other end of the second tube body 16 is connected to the interior of the waste heat recovery device 10. The setting of the heat sink 15 plays a fixing role on the first tube body 14 and the second tube body 16.

[0028] In one embodiment, an exhaust pipe 17 is installed on one side of the waste heat recovery device 10, a water inlet pipe 18 is installed on the outer wall of the waste heat recovery device 10, and a sewage pipe 19 is installed on one side of the waste heat recovery device 10. Through the setting of the waste heat recovery device 10, the exhaust pipe 17, the water inlet pipe 18 and the sewage pipe 19 are fixed. Through the setting of the temperature difference generator 11, the waste heat of coal combustion can be converted into electrical energy, and the electrical energy is stored in the battery 12, so that the battery 12 powers the water pump 13, so that the device can work without an external power supply, thereby improving the utilization efficiency of coal combustion heat storage.

[0029] In one embodiment, the adjustment assembly 201 includes a first slide rail 20, a first fixed block 21, a first fixed bolt 22, a second fixed block 23, a second slide rail 24, a second fixed bolt 25 and a clothes drying rod 26; the first slide rail 20 is installed on one side of the heat sink 15, and one side of the first fixed block 21 is slidably connected to the inside of the first slide rail 20. The first slide rail 20 is fixed by the setting of the heat sink 15.

[0030] In one embodiment, a first fixing bolt 22 is installed on one side of the first fixing block 21, a second slide rail 24 is installed on one side of the heat sink 15, and one side of the second fixing block 23 is slidably connected to the inside of the second slide rail 24. The second slide rail 24 is fixed by the setting of the heat sink 15.

[0031] In one embodiment, a second fixing bolt 25 is installed on one side of the second fixing block 23, and one side of the clothesline 26 is hinged to one side of the heat sink 15. The setting of the heat sink 15 fixes the clothesline 26. Through the setting of the clothesline 26, clothes can be dried while providing heat.

[0032] When the utility model is working: firstly, heating liquid is added to the waste heat recovery device 10 through the water inlet pipe 18, and the waste heat recovery device 10 recovers the high-temperature flue gas in the flue gas pipe 30, and transfers the heat to the inside of the waste heat recovery device 10, thereby heating the liquid inside the waste heat recovery device 10, and the high-temperature flue gas will become low-temperature flue gas and be discharged from the flue gas pipe 30. Through the setting of the temperature difference generator 11, the waste heat of coal combustion can be converted into electrical energy, and the electrical energy is stored in the battery 12, so that the battery 12 supplies power to the water pump 13, so that the device can work without an external power supply, which improves the efficiency of combustion. The utilization efficiency of coal heat storage is improved. After heating is completed, the water pump 13 transports the heated liquid to the heat sink 15, and the heat is dissipated through the heat sink 15 to provide heating. The water that has lost its high temperature flows back to the waste heat recovery device 10 from the second tube body 16, and then is heated again to achieve the purpose of circulating heating. By adjusting the setting of the adjustment component 201, when it is necessary to dry some longer clothes, the angle of the clothes drying rod 26 can be flipped by adjusting the first fixed block 21 and the second fixed block 23 to avoid the situation where the clothes are covered on the heat sink 15 and the heat cannot be dissipated. It is very practical.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
