[0025] The utility model provides a methanol reforming combustion furnace to reduce energy consumption and thus reduce costs. The following will be described in detail with specific embodiments.

[0026] As Figure 1 shown, a methanol reforming combustion furnace provided by an embodiment of the utility model includes a furnace body 1, a fuel cavity 2, and a metal coil 3; the fuel cavity 2 is arranged in the inner cavity of the furnace body 1, and the fuel cavity 2 is provided with a combustion assembly; the metal coil 3 is arranged in the inner cavity of the furnace body 1 and above the fuel cavity 2, the metal coil 3 has a feed end 31 and a discharge end 32, the feed end 31 passes through the wall of the furnace body 1 and extends outside the furnace body 1, the feed end 31 is used to communicate with a methanol container, and the discharge end 32 is communicated with the fuel cavity 2.

[0027] It should be noted that the metal coil 3 is arranged in the inner cavity of the furnace body 1 and above the fuel cavity 2, which means that the main part of the metal coil 3 is located in the inner cavity of the furnace body 1 and above the fuel cavity 2, and for example, the feed end 31 and the discharge end 32 can extend outside the furnace body 1 or be connected to the fuel cavity 2. Specifically, the upper end of the furnace body 1 can be an open setting so that the heat generated by combustion in the furnace body 1 can be transferred upward to the device to be heated above the combustion furnace.

[0028] In this embodiment, the feed end 31 of the metal coil 3 passes through the wall of the furnace body 1 and extends outside the furnace body 1 and can be communicated with a methanol container, the discharge end 32 of the metal coil 3 is communicated with the fuel cavity 2 to convey the methanol in the methanol container to the fuel cavity 2, and the metal coil 3 is arranged in the inner cavity of the furnace body 1 and above the fuel cavity 2 so that when the combustion assembly burns the fuel in the fuel cavity 2, the heat generated by combustion can flow upward to heat the metal coil 3, thereby heating the methanol conveyed in the metal coil 3. That is, the methanol heating utilizes the heat generated by the combustion heat supply of the combustion furnace itself, and there is no need to additionally set a heating device to separately heat the methanol, which is beneficial to reducing the energy consumption of the combustion furnace and further reducing the use cost.

[0029] Optionally, as Figure 1 shown, the methanol reforming combustion furnace further includes a methanol reforming catalytic converter 4, a first metal connecting pipe 5, and a second metal connecting pipe 6. The methanol reforming catalytic converter 4 is arranged outside the furnace body 1, and a methanol reforming catalyst is arranged in the methanol reforming catalytic converter 4. The first metal connecting pipe 5 penetrates through the wall of the furnace body 1, and its two ends are respectively communicated with the discharge end 32 and the methanol reforming catalytic converter 4. The second metal connecting pipe 6 penetrates through the wall of the furnace body 1, and its two ends are respectively communicated with the methanol reforming catalytic converter 4 and the fuel cavity 2.

[0030] In this alternative embodiment, the first metal connecting pipe 5 and the second metal connecting pipe 6 can enable the methanol reforming catalytic converter 4 to be respectively connected to the discharge end 32 and the fuel cavity 2, that is, the discharge end 32 is indirectly connected to the fuel cavity 2 through the methanol reforming catalytic converter 4, so that the methanol sent out from the discharge end 32 must pass through the methanol reforming catalytic converter 4 before entering the fuel cavity 2. The heated methanol will be catalytically cracked into a reforming mixed gas containing hydrogen and carbon monoxide in the methanol reforming catalytic converter 4, and these gases can release more energy during combustion, improving the combustion efficiency; and optionally, it is also possible to arrange the methanol reforming catalytic converter 4 beside or below the fuel cavity 2 inside the furnace body 1 to form an integrated design of the furnace body 1 and the methanol reforming catalytic converter 4. The above changes all fall within the protection scope of the utility model patent.

[0031] Optionally, as Figure 1 shown, the metal coiled pipe 3 is spirally extended along the up and down direction.

[0032] Specifically, hooks can be provided on the inner wall of the upper part of the inner cavity of the furnace body 1, and the metal coiled pipe 3 can be hung on the hooks so that the metal coiled pipe 3 is suspended above the fuel cavity. It should be noted that the metal coiled pipe 3 being spirally extended along the up and down direction means that the metal coiled pipe 3 is generally spiral-shaped, and the axis of the spiral structure is parallel to the up and down direction.

[0033] In this alternative embodiment, making the metal coiled pipe 3 spiral can increase the surface area of the metal coiled pipe 3, thereby improving the heat exchange efficiency and further enhancing the heating effect on methanol.

[0034] Optionally, as Figure 1 shown, the shape of the orthographic projection of the metal coiled pipe 3 on the horizontal plane is square, rectangular, circular or elliptical.

[0035] It should be noted that after the metal coiled pipe 3 is spirally extended, the metal coiled pipe 3 is generally in a cylindrical structure as a whole, and the shape of the orthographic projection of the metal coiled pipe 3 on the horizontal plane is the cross-sectional shape of the cylindrical structure, which can be square, rectangular, circular or elliptical. For example, when the orthographic projection shape is square, the metal coiled pipe 3 is a square cylindrical structure.

[0036] In this alternative embodiment, the orthographic projection shape of the metal coiled pipe 3 can adopt one of square, rectangular, circular and elliptical. The above coiled pipe shapes are relatively simple and easy to manufacture.

[0037] Optionally, as Figure 1 and Figure 2As shown, the combustion assembly includes a combustion tube 7 and an ignition module. The combustion tube 7 penetrates through the upper cavity wall of the fuel cavity 2, and its upper end is exposed on the upper end surface of the fuel cavity 2. The ignition module is arranged at the upper end of the fuel cavity 2 and is used to ignite the fuel flowing out of the combustion tube 7.

[0038] It should be noted that the ignition module is one of the common components of the combustion furnace, and its specific structure is not described in detail in this embodiment.

[0039] In this alternative embodiment, the combustion assembly includes a combustion tube 7 and an ignition module. Among them, the combustion tube 7 is connected to the fuel cavity 2 to conduct the fuel in the fuel cavity 2, and the ignition module can ignite the fuel flowing out of the combustion tube 7 to achieve fuel combustion.

[0040] Optionally, as Figure 2 shown, a plurality of the combustion tubes 7 are provided. The plurality of combustion tubes 7 are arranged on the upper cavity wall of the fuel cavity 2 and are evenly spaced in the horizontal direction.

[0041] In this alternative embodiment, the uniformly distributed plurality of combustion tubes 7 can ensure that the fuel is evenly distributed above the fuel cavity 2, achieving a more uniform combustion effect, thereby improving the heating effect on the methanol in the metal coil 3.

[0042] Optionally, as Figure 2 shown, a vertically arranged first retaining wall 21 is provided at the edge of the upper end surface of the fuel cavity 2. The first retaining wall 21 extends along the circumference of the upper end surface of the fuel cavity 2, and the first retaining wall 21 and the upper end surface of the fuel cavity 2 jointly define a first methanol overflow tank 22.

[0043] It can be understood that when methanol is not heated, it is in a low-temperature liquid state and will not undergo a reforming catalytic reaction with the methanol reforming catalyst in the methanol reforming catalyst 4. Therefore, when methanol starts to flow into the metal coil 3, there is no fuel in the fuel cavity 2 and it will not burn. As a result, the methanol flowing into the metal coil 3 will not be heated. The methanol will flow through the metal coil 3, the methanol reforming catalyst 4, and the fuel cavity 2 in sequence and always remain in a liquid state. When the liquid methanol enters the fuel cavity 2, it may overflow from the combustion tube 7 and flow away along the peripheral wall surface of the fuel cavity 2, resulting in fuel waste and fire hazard. In this alternative embodiment, a vertically arranged first retaining wall 21 is provided at the edge of the upper end surface of the fuel cavity 2, and the first retaining wall 21 extends along the circumference of the upper end surface of the fuel cavity 2, so that the first retaining wall 21 and the upper end surface of the fuel cavity 2 jointly define a first methanol overflow tank 22. In this way, even if a small amount of liquid methanol overflows from the combustion tube 7, the first methanol overflow tank 22 can block the liquid methanol, causing the overflowed liquid methanol to stay on the upper end surface of the fuel cavity 2, facilitating ignition and combustion later, reducing methanol waste and avoiding fire hazard.

[0044] Optionally, as Figure 2 shown, a horizontally arranged second retaining wall 23 is provided at the lower edge of the peripheral wall surface of the fuel cavity 2. The second retaining wall 23 extends along the circumference of the peripheral wall surface of the fuel cavity 2. A vertically arranged third retaining wall 24 is provided on the outer peripheral side of the second retaining wall 23. The third retaining wall 24 extends along the circumference of the second retaining wall 23. The third retaining wall 24, the second retaining wall 23, and the peripheral wall surface of the fuel cavity 2 jointly define a second methanol overflow tank 25.

[0045] In this alternative embodiment, the second retaining wall 23 and the third retaining wall 24 are used to jointly define a second methanol overflow tank 25 with the peripheral wall surface of the fuel cavity 2. In this way, even if the liquid methanol overflows from the first methanol overflow tank 22, the second methanol overflow tank 25 can block the liquid methanol, preventing the liquid methanol from flowing away and volatilizing, facilitating ignition and combustion, and reducing methanol waste.

[0046] Optionally, as Figure 1 and Figure 2 shown, the combustion assembly further includes a combustion-supporting gas pipe 8. The combustion-supporting gas pipe 8 includes an outlet pipe 81 and an inlet pipe 82. The outlet pipe 81 penetrates through the upper cavity wall of the fuel cavity 2, and its upper end is exposed on the upper end surface of the fuel cavity 2. One end of the inlet pipe 82 is communicated with the lower end of the outlet pipe 81, and the other end is exposed to the outside of the furnace body 1 and is used to communicate with a combustion-supporting gas container.

[0047] In this alternative embodiment, the combustion-supporting gas pipe 8 includes a connected air outlet pipe 81 and an air inlet pipe 82. The air outlet pipe 81 penetrates through the upper cavity wall of the fuel cavity 2, and the air inlet pipe 82 can be connected to a combustion-supporting gas container. In this way, the combustion-supporting gas in the combustion-supporting gas container can be sent to the upper end of the fuel cavity 2 through the air outlet pipe 81. The combustion-supporting gas can be, for example, oxygen. The combustion-supporting gas helps the complete combustion of the fuel, improves the combustion efficiency, and thus reduces the fuel cost.

[0048] Optionally, as Figure 2 shown, a plurality of the air outlet pipes 81 are provided. The plurality of air outlet pipes 81 are arranged on the upper cavity wall of the fuel cavity 2 and are evenly spaced in the horizontal direction.

[0049] In this alternative embodiment, the uniformly distributed plurality of air outlet pipes 81 can ensure the uniform distribution of the combustion-supporting gas above the fuel cavity 2, achieve a better combustion-supporting effect, and further reduce the fuel cost. However, optionally, the combustion-supporting gas pipe 8 can be cancelled, and it is also possible to rely only on the air entering through the furnace body shell 1 for combustion support. The above changes all fall within the protection scope of the utility model patent.

[0050] Although the present utility model is disclosed as above, the protection scope of the present utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model, and these changes and modifications will all fall within the protection scope of the present utility model.
