Such direct discharge causes a lot of heat waste; there is also a method in the existing technology to directly use the smoke pipe to preheat the combustion air in the air pipeline of the torpedo tank baking burner, but the heat release of the smoke gas in the smoke pipe is insufficient.

[0003] Therefore, it is necessary to further optimize and improve the heat exchange burner for torpedo tank baking so as to efficiently utilize the flue gas heat and avoid the waste of gas energy and congestion of on-site space. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0024] As shown in Figures 1-3, a heat exchange burner for baking torpedo tanks comprises a Y-shaped burner 1, a gas pipe 2, an air blast pipe 3, a connecting cover 4, a flue gas pipe 5, an air distribution duct 6, heat exchange fins 7, a first connecting plate 9, and a second connecting plate 10. The Y-shaped burner 1 is connected to the gas pipe 2 and the air blast pipe 3, respectively. The Y-shaped burner 1 serves as a flame outlet during baking and is used to reduce pressure loss between the gas medium and its combustion-supporting medium. The gas pipe 2, used to transport the baking gas medium, is concentrically nested within the air blast pipe 3, with the two being welded axially to each other via a plurality of first connecting plates 9. The air blast pipe 3, used to transport the baking combustion-supporting medium (such as air), passes through the center of the connecting cover 4, and the two are welded to each other. The right end (the air inlet end) of the air blast pipe 3 is concentrically nested within the flue gas pipe 5 (hereinafter referred to as the second flue gas pipe 52), with the two being welded axially to each other via a plurality of second connecting plates 10. The flue gas pipe 5, used to exhaust the flue gas generated during baking, is welded to the right end of the connecting cover 4. The air distribution duct 6 is used to increase the blast path, adjust the blast direction, and increase the contact area and duration with the flue gas pipe 5 (heat dissipation fins). The air distribution duct 6 is sleeved onto the outer layer of the flue gas pipe 5 and is connected to the blast duct 3. The heat exchange fins 7 are fixed to the flue gas pipe 5 and arranged between the air distribution duct 6 and the flue gas pipe 5. The heat exchange fins 7 are used to increase the heat exchange efficiency between the flue gas and the combustion air, effectively releasing the heat in the flue gas pipe 5 into the air distribution duct 6 or the blast duct 3, thereby increasing the temperature of the combustion air and achieving better combustion. The first connecting plate 9 and the second connecting plate 10 are not limited in structure and are both steel plates used for structural connection.

[0025] In this embodiment, the flue gas duct 5 includes a first flue gas duct 51 and a second flue gas duct 52, which are vertically connected as a whole. The first flue gas duct 51 is arranged vertically, while the second flue gas duct 52 is arranged horizontally. The air distribution duct 6 includes a first air duct 61 and a second air duct 62, which are vertically connected as a whole. The first air duct 61 is arranged vertically, while the second air duct 62 is arranged horizontally. The first air duct 61 is concentrically sleeved on the outer layer of the first flue gas duct 51, while the second air duct 62 is concentrically sleeved on the outer layer of the second flue gas duct 52. In this way, by configuring the air distribution duct 6 within the flue gas duct 5 within the blast duct 3 within the gas pipe 2, this device eliminates the need for an external heat exchanger on the burner and can achieve heat exchange directly within the entire burner, thus reducing occupied space, conserving heat, and reducing heat escape from the flue gas.

[0026] In this embodiment, the heat exchange fins 7 include first fins 71 and second fins 72, wherein the first fins 71 are fixed to the first smoke tube 51, and the second fins 72 are fixed to the second smoke tube 52. Thus, by providing two sets of fins, the device can more effectively release heat from the smoke tube 5 to the air distribution tube 6 or the blast tube 3, further improving the heat exchange efficiency and the combustion air temperature, and achieving a better combustion effect.

[0027] The beneficial effects of this embodiment are as follows: the arrangement of the heat exchange fins 7 helps to release the heat of the flue gas, which can improve the heat exchange efficiency and the temperature of the combustion air, and achieve a better combustion effect; the arrangement of the sleeve structure of each pipeline can save heat, reduce the escape of flue gas heat, and reduce the occupied space.

The Y-shaped burner 1 is connected to the gas pipe 2 and the air blast pipe 3, respectively. The Y-shaped burner 1 serves as a flame outlet during baking and is used to reduce pressure loss between the gas medium and its combustion-supporting medium. The gas pipe 2, used to transport the baking gas medium, is concentrically nested within the air blast pipe 3, with the two being welded axially to each other via a plurality of first connecting plates 9. The air blast pipe 3, used to transport the baking combustion-supporting medium (such as air), passes through the center of the connecting cover 4, and the two are welded to each other. The right end (the air inlet end) of the air blast pipe 3 is concentrically nested within the flue gas pipe 5 (hereinafter referred to as the second flue gas pipe 52), with the two being welded axially to each other via a plurality of second connecting plates 10. The flue gas pipe 5, used to exhaust the flue gas generated during baking, is welded to the right end of the connecting cover 4. The air distribution duct 6 is used to increase the blast path, adjust the blast direction, and increase the contact area and duration with the flue gas pipe 5 (heat dissipation fins). The air distribution duct 6 is sleeved onto the outer layer of the flue gas pipe 5 and is connected to the blast duct 3.

Thus, by providing two sets of fins, the device can more effectively release heat from the smoke tube 5 to the air distribution tube 6 or the blast tube 3, further improving the heat exchange efficiency and the combustion air temperature, and achieving a better combustion effect.

[0031] In this embodiment, an air path extension 8 is provided within the second air duct 62 of the air distribution duct 6. This air path extension 8 can be a tubular structure concentric with the second air duct 62 or a curved plate-like structure. The air path extension 8 divides the air distribution duct 6 into a first air inlet area 13 and a second air inlet area 14. The first air inlet area 13 is an L-shaped air path for air from the first air duct 61 to enter the second air duct 62, while the second air inlet area 14 is a horizontal air path within the second air duct 62. The first air inlet area 13, the second air inlet area 14, and the blower duct 3 are sequentially connected. The first fin 71 is provided within the first air inlet area 13, and the second fin 72 is provided within the second air inlet area 14.

[0054] By arranging the heat exchange fins 7 on the flue gas pipe 5, the heat in the flue gas can be effectively released to the blast pipe 3, thereby increasing the combustion air temperature, improving the heat exchange efficiency, and achieving a better combustion effect.

[0055] Through the heat exchange structure of 6 sets of air distribution pipes, 5 sets of flue pipes, 3 sets of blast pipes and 2 sets of gas pipes, this device does not require an external heat exchanger on the burner, and can directly achieve heat exchange inside the entire burner. It occupies less space than the general roaster with external heat exchanger, and can be used in more demanding space conditions, thus avoiding the waste of gas energy and the congestion of on-site space.

[0056] By providing the air path extension portion 8 in the air distribution duct 6, the air blowing path, heat exchange area and heat exchange time can be increased without expanding the space occupied by the entire device, thereby improving space utilization and heat exchange efficiency.

[0057] By providing detachable connections for each flange, the device can be easily disassembled and assembled, replaced and repaired, and is more convenient to use.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
