[0036] Please see Figures 1 to 3 This application provides a combustion device 100 and a float glass production system having the same. The combustion device 100 can burn gas to serve as a heat source for the float glass production system.
[0037] Please see Figures 1 to 3 The combustion device 100 includes: a combustion furnace 20, a spray gun assembly 10, and a gas supply assembly.
[0038] Please see Figures 1 to 3 The combustion furnace 20 has a combustion chamber 201. The surface of the combustion furnace 20 is provided with mounting holes that communicate with the combustion chamber 201. Multiple mounting holes are provided, and each mounting hole is located on the same surface of the combustion furnace 20 and is arranged at intervals along a first direction. It can be understood that the combustion furnace 20 can be a small furnace in a float glass production system. The small furnace includes side walls 22, a small furnace arch 21, and a bottom plate structure 23. Two side walls 22 are arranged opposite each other. The two side walls 22, the small furnace arch 21, and the bottom plate structure 23 together form the combustion chamber 201. Each mounting hole is located on one of the side walls 22 and is arranged linearly along the first direction. In this embodiment, the first direction is parallel to the horizontal plane and parallel to the flow direction of the glass in the combustion chamber 201.
[0039] Please see Figures 1 to 3The spray gun assembly 10 includes a first spray gun 11 and a second spray gun 12. Along the first direction, the second spray gun 12 is disposed in each of the two mounting holes located at the beginning and end, and the first spray gun 11 is disposed in each of the other mounting holes. It can be understood that, along the first direction, each first spray gun 11 is located between two second spray guns 12. In this embodiment, the number of mounting holes is four, with two first spray guns 11 disposed in each of the two middle mounting holes, and two second spray guns 12 disposed in each of the two beginning and end mounting holes. In other embodiments, the number of mounting holes may be five or more; this is not limited here and can be selected according to actual conditions.
[0040] A gas supply assembly is used to supply gas to the first spray gun 11 and the second spray gun 12 so that both the first spray gun 11 and the second spray gun 12 generate flames along a second direction, wherein the first direction is perpendicular to the second direction; it can be understood that both the first direction and the second direction are parallel to the horizontal plane, the first direction can be represented as the X direction, and the second direction can be represented as the Y direction.
[0041] Please see Figures 1 to 3 The gas supply assembly supplies more gas to the first spray gun 11 than to the second spray gun 12, so that the flame length produced by the first spray gun 11 is greater than the flame length produced by the second spray gun 12. It can be understood that, along the first direction, the two first spray guns 11 are located in the middle of the combustion chamber 201. Compared to the second spray guns 12 on both sides, the areas of the two first spray guns 11 are wider, thus having more sufficient air. The second spray guns 12 on both sides, due to the confinement of the walls of the combustion chamber 201, have a narrower area and insufficient air to mix with the combustion gas flowing from the second spray guns 12. Therefore, the combustion gas flowing from each of the first spray guns 11 can mix more thoroughly with air than that from the second spray guns 12, resulting in more complete combustion.
[0042] With the gas supply of the gas supply assembly at its rated capacity, increasing the gas supply to the first spray gun 11 allows it to produce a longer and thicker flame. A longer flame positions the high-temperature zone of the flame closer to the center of the combustion chamber 201, enabling the flames of each first spray gun 11 to radiate heat to the periphery of the combustion chamber 201, thus improving the uniformity of overall heat radiation. Furthermore, with more gas burning in the first spray gun 11 and less in the second spray gun 12, more gas is burned completely, reducing gas consumption and saving energy.
[0043] In this embodiment, multiple mounting holes are arranged at intervals along the first direction on the same surface of the combustion furnace 20, and second spray guns 12 with shorter flame lengths are set at the beginning and end ends, while first spray guns 11 with longer flame lengths are set at the remaining positions. Thus, with a fixed gas supply, more gas can be fully burned in the first spray gun 11, reducing the amount of gas used. The longer flame of the first spray gun 11 can improve the uniformity of heat radiation in the combustion chamber 201, achieving a uniform temperature distribution in the combustion chamber 201, thereby improving the quality of glass production and saving fuel consumption.
[0044] Please see Figures 1 to 3 In some embodiments, the inner diameter of the combustion end of the first spray gun 11 is larger than the inner diameter of the combustion end of the second spray gun 12, so that the gas flow rate of the first spray gun 11 is greater than the gas flow rate of the second spray gun 12, and finally the flame length of the first spray gun 11 is greater than the flame length of the second spray gun 12, thereby improving the uniformity of heat radiation and making the temperature in the combustion chamber 201 uniformly distributed.
[0045] Please see Figure 4 and Figure 5 In some embodiments, the first spray gun 11 includes a first outer tube 112, a first nozzle 111 disposed at one end of the first outer tube 112, and a first inner tube 113 located at least partially inside the first outer tube 112, wherein the combustion end of the first spray gun 11 is disposed at the first nozzle 111.
[0046] Please see Figure 4 and Figure 5 The second spray gun 12 includes a second outer tube 122, a second nozzle 121 disposed at one end of the second outer tube 122, and a second inner tube 123 located at least partially inside the second outer tube 122. The combustion end of the second spray gun 12 is disposed at the second nozzle 121.
[0047] Please see Figure 4 and Figure 5 Optionally, the first gun head 111, the second gun head 121, the first outer tube 112, the first inner tube 113, the second outer tube 122, and the second inner tube 123 can all be made of refractory materials, such as metallic copper.
[0048] Please see Figure 4 and Figure 5 The first outer tube 112 and the second outer tube 122 are both provided with external threads, and the first gun head 111 and the second gun head 121 are both provided with internal threads, so that the first gun head 111 and the second gun head 121 can be screwed into the first outer tube 112 and the second outer tube 122 respectively.
[0049] Please see Figure 4 and Figure 5The first nozzle 111 has a first air outlet 114 located in the combustion chamber 201, and the second nozzle 121 has a second air outlet 124 located in the combustion chamber 201. The inner diameter of the first air outlet 114 is larger than the inner diameter of the second air outlet 124.
[0050] Please see Figure 4 and Figure 5 It is understandable that the first air outlet 114 is located on the end face of the first nozzle 111, and the second air outlet 124 is located on the end face of the second nozzle 121, so that more gas flows out from the first air outlet 114 and mixes with the air in the combustion chamber 201, ensuring that the flame length of the first spray gun 11 is greater than the flame length of the second spray gun 12.
[0051] Please see Figure 4 and Figure 6 In some embodiments, the inner diameter of the first air outlet 114 is in the range of 42 to 46 mm.
[0052] It is understandable that the first air outlet 114 is circular in shape, and its inner diameter can be 42mm, 42.15mm, 42.87mm, 43.22mm, 43.56mm, 44.03mm, 44.41mm, 44.92mm, 45.18mm, 45.67mm, 45.99mm or 46mm.
[0053] Please see Figure 4 and Figure 6 In this embodiment, the inner diameter of the first air outlet 114 is 45mm, which enables the flame generated by the first spray gun to have a certain rigidity, that is, the length direction of the flame is basically parallel to the horizontal direction, so that the flame will not bend downward or tilt, which is beneficial to improving the uniformity of heat radiation. In other embodiments, the appropriate method can be selected according to the actual situation, and there is no limitation here.
[0054] Optionally, the flame length produced by the first spray gun ranges from 9 to 10 meters.
[0055] Optionally, by limiting the inner diameter of the first air outlet 114 to the range of 42 to 46 mm, it is ensured that the first spray gun 11 produces a flame of appropriate length to match the heat radiation requirements of the middle position, thereby achieving precise temperature control in the overall combustion device 100 and improving the uniform heating effect of the float glass melting section.
[0056] Please see Figure 5 and Figure 7 In some embodiments, the inner diameter of the second air outlet 124 is in the range of 38 to 40 mm.
[0057] Understandably, the second air outlet 124 is circular in shape, and its inner diameter can be 38mm, 38.12mm, 38.35mm, 38.54mm, 38.67mm, 38.82mm, 38.91mm, 39.08mm, 39.27mm, 39.49mm, 39.78mm or 40mm.
[0058] Please see Figure 5 and Figure 7 In this embodiment, the inner diameter of the second air outlet 124 is 40mm, which enables the flame generated by the second spray gun to have a certain rigidity, that is, the length direction of the flame is basically parallel to the horizontal direction, so that the flame will not bend downward or tilt, which is beneficial to improving the uniformity of heat radiation. In other embodiments, the appropriate method can be selected according to the actual situation, and there are no restrictions here.
[0059] Optionally, the flame length produced by the second spray gun ranges from 7 to 8 meters.
[0060] Optionally, by limiting the inner diameter of the second air outlet 124 to the range of 38 to 40 mm, it is ensured that the second spray gun 12 produces a shorter flame to meet the heat radiation requirements at the beginning and end positions, thereby forming a balanced heat distribution pattern in the combustion chamber 201.
[0061] Optionally, both the first inner tube 113 and the second inner tube 123 have circular cross-sections, and the outer diameters of the first inner tube 113 and the second inner tube 123 are the same. Therefore, the amount of gas flowing out of the first gas outlet 114 per unit time is greater than the amount of gas flowing out of the second gas outlet 124.
[0062] Optionally, the first inner tube 113 and the second inner tube 123 have the same structure and size, that is, the first inner tube 113 and the second inner tube 123 are two identical components, thus enabling mass production and facilitating maintenance and replacement.
[0063] Please see Figure 1 In some embodiments, the mounting holes are arranged at equal intervals along the first direction.
[0064] Optionally, by arranging the mounting holes at equal intervals along the first direction, the uniform distribution of the first spray gun 11 and the second spray gun 12 is ensured, thereby improving the overall uniformity of heat radiation within the combustion chamber 201 based on the difference in flame length.
[0065] Please see Figure 1 In some embodiments, the distance between any two adjacent mounting holes ranges from 680 to 700 mm.
[0066] It is understood that the distance between any two adjacent mounting holes can be 680mm, 683mm, 685mm, 688mm, 690mm, 692mm, 694mm, 696mm, 698mm, 699mm or 700mm.
[0067] In this embodiment, the spacing between any two adjacent mounting holes is 690. In other embodiments, the spacing can be selected according to the actual situation, and no restriction is imposed here.
[0068] Optionally, by limiting the distance between adjacent mounting holes to the range of 680 to 700 mm, the flame length difference between the first spray gun 11 and the second spray gun 12 is achieved, thereby optimizing the temperature distribution in the combustion chamber 201 and improving the uniformity of heat radiation.
[0069] Please see Figure 2 In some embodiments, the distance between any two adjacent first spray guns 11 is a, and the distance between any second spray gun 12 and an adjacent first spray gun 11 is b, where b is greater than a.
[0070] Optionally, by setting the distance a between adjacent first spray guns 11 to be less than the distance b between adjacent second spray guns 12 and first spray guns 11, the arrangement of the first and last second spray guns 12 and the middle first spray gun 11 is made more compact, thereby achieving refined thermal radiation compensation under the difference in flame length and improving the overall temperature uniformity of the combustion chamber 201.
[0071] Optionally, a can be 680mm and b can be 650mm. Along the first direction, the first spray gun 11 is brought close to the second spray gun 12. This means that the first spray gun 11 is brought closer to the middle position of the combustion chamber 201, so that the space where the first spray gun 11 is located is relatively wide. The gas flowing out from the first spray gun 11 can be fully mixed with the air, thereby improving the combustion efficiency of the first spray gun 11 and at the same time taking into account the uniformity of the heat radiation of the first spray gun 11.
[0072] In some embodiments, the air supply assembly includes an air source, an air supply pipe connected to the air source, and a control valve disposed on the air supply pipe, wherein each of the first spray guns 11 and each of the second spray guns 12 are connected to the air supply pipe.
[0073] Optionally, the gas source includes a gas cylinder and fuel gas stored in the cylinder; the fuel gas may be hydrogen. Precise control of the fuel gas supply is achieved through a gas supply assembly.
[0074] Please see Figures 1 to 3This utility model also proposes a float glass production system, which includes a combustion device 100. The specific structure of the combustion device 100 is as described in the above embodiments. Since this float glass production system adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0075] By integrating the combustion device 100 into the float glass production system, the heat source supply of the melting furnace is optimized, improving the uniformity of heat radiation and fuel economy of the overall system. By setting two first spray guns 11 and two second spray guns 12, a larger longitudinal flame coverage area is achieved within the combustion chamber 201 along the first direction.
[0076] The above are merely optional embodiments of this application and are not intended to limit this application.
