[0028] In one embodiment of this utility model, such as Figures 1-3 As shown, an industrial thermal energy device with a waste heat recovery channel is provided, including a lower furnace body 1, an upper furnace body 2 and a waste heat recovery mechanism 3. The upper furnace body 2 is connected to the top side of the lower furnace body 1, and the waste heat recovery mechanism 3 is disposed between the lower furnace body 1 and the upper furnace body 2, and is connected to the lower furnace body 1 and the upper furnace body 2 respectively.

[0029] The lower furnace body 1 is provided with a lower waste heat recovery chamber 11, and the upper furnace body 2 is provided with an upper waste heat recovery chamber. The waste heat recovery mechanism 3 is respectively located in the lower waste heat recovery chamber 11 and the upper waste heat recovery chamber.

[0030] The waste heat recovery mechanism 3 includes a flue pipe 31, a waste heat recovery pipe 32, a first flue pipe seat 33, and a second flue pipe seat 34. The flue pipe 31 is S-shaped and is located inside the lower waste heat recovery chamber 11, with one end extending out of the lower furnace body 1. The waste heat recovery pipe 32 is wound around the outside of the flue pipe 31, with one end connected to the upper waste heat recovery chamber and the other end extending out of the lower furnace body 1 and the second flue pipe seat 34. The first flue pipe seat 33 is connected to one side of the lower furnace body 1 and to the outside of the flue pipe 31, while the second flue pipe seat 34 is connected to the other side of the lower furnace body 1 and to the outside of the flue pipe 31.

[0031] The industrial thermal energy equipment with waste heat recovery channel provided in this application increases the flow path and residence time of high-temperature flue gas in the exhaust pipe 31 by setting the exhaust pipe 31 in an S-shape in the lower waste heat recovery chamber 11. At the same time, the waste heat recovery pipe 32 is wrapped around the outside of the exhaust pipe 31, which can fully absorb the heat of the high-temperature flue gas in the exhaust pipe 31, significantly improving the waste heat recovery efficiency, realizing the efficient utilization of waste heat in the industrial production process, and reducing energy waste.

[0032] In another embodiment of this utility model, the diameter of the flue pipe 31 is larger than that of the waste heat recovery pipe 32, and the waste heat recovery pipe 32 is evenly wound around the outside of the flue pipe 31. This design allows the waste heat recovery pipe 32 to fully contact the flue pipe 31, increasing the heat exchange area and improving the waste heat recovery efficiency.

[0033] In another embodiment of this utility model, a support plate 12 is fixedly connected inside the lower furnace body 1. The support plate 12 is disposed inside the lower waste heat recovery chamber 11, and both the flue pipe 31 and the waste heat recovery pipe 32 are disposed on the support plate 12. The support plate 12 can support and fix the flue pipe 31 and the waste heat recovery pipe 32, ensuring the stability of the waste heat recovery mechanism 3 during equipment operation and preventing it from shaking or displacing.

[0034] In another embodiment of this utility model, a positioning seat 22 is provided on the side of the upper furnace body 2. The positioning seat 22 is fixedly connected to the upper furnace body 2, and the waste heat recovery pipe 32 is fixedly installed on the positioning seat 22 and extends into the upper waste heat recovery chamber. The positioning seat 22 provides a fixed support for the waste heat recovery pipe 32, making it easy to fix the waste heat recovery pipe 32 to the upper furnace body 2.

[0035] In another embodiment of this utility model, a fixing plate 4 is provided between the lower furnace body 1 and the upper furnace body 2, and the fixing plate 4 is fixedly connected to the lower furnace body 1 and the upper furnace body 2 respectively. The fixing plate 4 enhances the connection strength between the lower furnace body 1 and the upper furnace body 2 and improves the structural stability of the entire equipment.

[0036] In another embodiment of this utility model, a cover plate 5 is provided on the top side of the upper furnace body 2, and the cover plate 5 is fixedly connected to the upper furnace body 2.

[0037] In another embodiment of this utility model, a base 6 is provided on the bottom side of the lower furnace body 1. Multiple bases 6 are provided and are evenly fixedly connected to the lower furnace body 1. The base 6 suspends the bottom of the lower furnace body 1, thus preventing contamination.

[0038] The industrial thermal energy equipment with a waste heat recovery channel provided in this application operates as follows:

[0039] High-temperature flue gas generated during industrial production enters from one end of the exhaust pipe 31. Due to the S-shaped design of the exhaust pipe 31, the high-temperature flue gas flows slowly within it, prolonging the contact time with the inner wall of the exhaust pipe 31. A waste heat recovery pipe 32 is wound around the outside of the exhaust pipe 31, ensuring full contact with it. The heat from the high-temperature flue gas is transferred through heat conduction to the medium (such as air or water) within the waste heat recovery pipe 32, achieving waste heat recovery. The heated medium then enters the upper waste heat recovery chamber through the waste heat recovery pipe 32, where it can further exchange heat with other substances requiring heating, achieving waste heat reuse. The low-temperature flue gas, after waste heat recovery, exits the equipment from the other end of the exhaust pipe 31.

[0040] The industrial thermal energy equipment with waste heat recovery channel provided in this application increases the flow path and residence time of high-temperature flue gas in the exhaust pipe 31 by setting the exhaust pipe 31 in an S-shape in the lower waste heat recovery chamber 11. At the same time, the waste heat recovery pipe 32 is wrapped around the outside of the exhaust pipe 31, which can fully absorb the heat of the high-temperature flue gas in the exhaust pipe 31, significantly improving the waste heat recovery efficiency, realizing the efficient utilization of waste heat in the industrial production process, and reducing energy waste.

[0041] The above description is only a preferred embodiment of the present utility model and is 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.
