[0044] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0045] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0046] This utility model provides a methanol combustion system, which includes a methanol burner 010 (e.g., Figure 1 and Figure 2 (As shown). Please refer to... Figure 1 , Figure 2 and Figure 3 The methanol burner 010 includes a housing 100, a Brown gas pipe 200, a compressed air pipe 300, and a methanol pipe 400. The housing 100 has a first end and a second end that are relatively distributed, and the housing 100 is provided with an air duct 101 and a combustion air inlet 131 and a combustion air outlet connected to the air duct 101, with the combustion air outlet located at the first end. The Brown gas pipe 200 is assembled to the housing 100, and one end of the Brown gas pipe 200 is connected to a Brown gas nozzle 210, with the Brown gas nozzle 210 distributed outside the first end. The Brown gas pipe 200 is used for... The system is used to transport Brown gas and eject it from the Brown gas nozzle 210; a compressed air pipe 300 is assembled into the housing 100, and one end of the compressed air pipe 300 is connected to a methanol atomizing nozzle 310, which is distributed on the outside of the first end; a methanol pipe 400 is assembled into the housing 100 and is connected to the compressed air pipe 300, and the methanol pipe 400 is used to transport methanol; the compressed air pipe 300 is used to transport compressed gas and eject the methanol entering the compressed air pipe 300 along with the compressed gas from the methanol atomizing nozzle 310.
[0047] When using the methanol burner 010, Brown gas can be supplied via the Brown gas pipeline 200 and ignited as the ignition source for methanol combustion. Brown gas is a mixture of hydrogen and oxygen produced after water electrolysis. It burns stably and emits no greenhouse gases. Using Brown gas as the ignition source for methanol combustion ensures the stability and completeness of methanol combustion, thus mitigating the problem of incomplete combustion and reducing carbon emissions. The air duct 101, combustion air inlet 131, and combustion air outlet in the housing 100 maintain airflow inside the methanol burner 010, improving combustion retention in the event of unsuccessful ignition and preventing the risk of deflagration during re-ignition. This enhances the safety of the methanol burner 010 during use.
[0048] It should be understood that in other embodiments, at least one of the Brown gas pipe 200, the methanol pipe 400, and the compressed air pipe 300 may not be fitted into the housing 100.
[0049] Optionally, the housing 100 includes an end cap 110, a swirl vane 120, a first tube 130 (also referred to as an air housing 100) and a second tube 140 (also referred to as a flame guide tube). The first tube 130 and the second tube 140 are coaxially connected. The end cap 110 is connected to the end of the first tube 130 away from the second tube 140, and the swirl vane 120 is connected to the end of the second tube 140 away from the first tube 130. The inner cavities of the first tube 130 and the second tube 140 together form an air duct 101. The combustion air inlet 131 is disposed on the outer peripheral sidewall of the first tube 130, and the combustion air outlet is disposed on the swirl vane 120. The Brown gas nozzle 210 and the methanol atomizing nozzle 310 are both distributed on the side of the swirl vane 120 away from the air duct 101, that is, the end where the swirl vane 120 is located is the first end of the housing 100, and the end where the end cap 110 is located is the second end of the housing 100. When using the methanol burner 010, the combustion air enters the air duct 101 from the combustion air inlet 131 and exits from the combustion air outlet opened by the swirl vane 120.
[0050] The connection methods of the end cap 110 and the first tube 130, the connection methods of the first tube 130 and the second tube 140, and the connection methods of the second tube 140 and the swirl vane 120 include, but are not limited to, connection with fasteners such as bolts, welding, and threaded connection.
[0051] It should be noted that a cavity sleeve (not shown in the figure) is provided at the end of the second tube 140 away from the first tube 130. The Brown gas nozzle 210 and the methanol atomizing nozzle 310 are both located inside the cavity sleeve, and the swirl vane 120 is distributed opposite to the inner cavity of the cavity sleeve so that the combustion of methanol takes place in the inner cavity of the cavity sleeve.
[0052] Please refer to Figure 2 and Figure 4 In this embodiment, the Brown gas pipe 200 is configured to be movably mounted on the housing 100, and the Brown gas pipe 200 can drive the Brown gas nozzle 210 to move synchronously along the axial direction of the housing 100. This configuration allows for adjustment of the position of the Brown gas nozzle 210 by adjusting the position of the Brown gas pipe 200, ensuring that the flame at the Brown gas nozzle 210 can reliably contact the methanol mist ejected from the methanol atomizing nozzle 310, thereby improving the completeness of methanol combustion.
[0053] Of course, in other embodiments, the Brown gas pipe 200 can also be fixedly mounted to the housing 100, and the flow rate of the Brown gas delivered by the Brown gas pipe 200 can be controlled to ensure sufficient contact between the Brown gas flame and the methanol.
[0054] Furthermore, the two ends of the Brown gas pipe 200 are respectively inserted into the first end and the second end. Specifically, the two ends of the Brown gas pipe 200 are respectively inserted into the end of the end cap 110 and the swirl vane 120, and the Brown gas pipe 200 passes through the air duct 101. The two ends of the Brown gas pipe 200 are respectively threadedly connected to two threaded parts 220, and the two threaded parts 220 are respectively distributed on the outside of the first end and the second end, that is, two nuts are respectively distributed on the side of the end cap 110 and the swirl vane 120 away from the air duct 101. The aforementioned threaded parts 220 can refer to nuts. With this configuration, the axial position of the Brown gas pipe 200 in the housing 100 can be adjusted by rotating the Brown gas pipe 200 or the nuts, thereby realizing the relative axial position of the Brown gas nozzle 210 and the methanol atomizing nozzle in the housing 100.
[0055] Please refer to Figure 3 In this embodiment, one end of the methanol pipe 400 is inserted into the end of the end cap 110, and the methanol pipe 400 extends into the air duct 101. The other end of the methanol pipe 400 is connected to an air outlet 410, which extends into the compressed air pipe 300. That is, the methanol pipe 400 is connected to the compressed air pipe 300 through the air outlet 410. The air outlet 410 is constricted, meaning that the inner diameter of the air outlet 410 gradually decreases from the end near the methanol pipe 400 to the end away from the methanol pipe 400. By setting the constricted air outlet 410, the resistance to methanol output from the methanol pipe 400 can be increased, which helps to prevent the negative pressure generated by the fast-flowing compressed air in the compressed air pipe 300 from drawing out the methanol in the methanol pipe 400 too quickly, thereby achieving methanol flow control. When the power of methanol burner 010 needs to be adjusted, it can be achieved by increasing or decreasing the methanol delivery pressure and the compressed air flow rate. For example, when methanol burner 010 needs to increase its power, the methanol pressure can be increased to increase the methanol flow rate, while the compressed air flow rate can be adjusted to ensure the methanol atomization quality.
[0056] Furthermore, the end of the methanol pipe 400 away from the end cap 110 has a bend to ensure that the outlet 410 connected to the end of the methanol pipe 400 away from the end cap 110 is reliably inserted into the compressed air pipe 300.
[0057] Please refer to Figure 3 In this embodiment, one end of the compressed air pipe 300 is inserted into the end cap 110, and the other end extends from the middle of the swirl vane 120 and is connected to the methanol atomizing nozzle 310. The Brown gas pipe 200 is distributed on one side of the compressed air pipe 300. This arrangement ensures that the methanol atomizing nozzle 310 is located in the middle of the swirl vane 120, which helps to ensure sufficient contact between the methanol and the Brown gas flame, thereby ensuring complete combustion.
[0058] Furthermore, the compressed air pipeline 300 includes a first pipeline and a second pipeline connected to each other, the first pipeline and the second pipeline being distributed at an angle to make the compressed air pipeline 300 form an L-shape; the end of the second pipeline away from the first pipeline is inserted into the side of the end cap 110, the axis of the first pipeline coincides with or substantially coincides with the axis of the housing 100, and the end of the first pipeline away from the second pipeline is connected to the methanol atomizing nozzle 310.
[0059] The connection methods for the first and second pipes include, but are not limited to, integral molding, welding, and threaded connection.
[0060] In other embodiments, the compressed air conduit 300 may consist only of a first conduit, the end of which, away from the methanol atomizing nozzle 310, is inserted into the end of the end cap 110.
[0061] Please refer to Figure 4 and Figure 5 Optionally, the spray angle of the methanol atomizing nozzle 310 is 60-80°. This setting ensures that the center of the methanol mist sprayed from the methanol atomizing nozzle 310 is hollow, which helps to ensure that the atomized methanol mist is fully mixed and in contact with the combustion air and Brown gas flame, thereby ensuring the efficiency and completeness of methanol combustion. If the methanol mist sprayed from the nozzle is solid, it is difficult to ensure that the methanol is mixed and in contact with the combustion air and Brown gas flame, making it difficult to improve combustion efficiency and ensure complete combustion.
[0062] Please refer to Figure 5 , Figure 6 and Figure 7In this embodiment, the housing 100 is provided with multiple combustion air outlets, including multiple first outlets 121 and multiple second outlets 122. The multiple first outlets 121 are all distributed around the outer periphery of the methanol atomizing nozzle 310, and the multiple second outlets 122 are arranged in a ring around the outer periphery of the multiple first outlets 121 along the circumference of the housing 100. Specifically, the multiple first outlets 121 are all located on the end face of the swirl vane 120 and distributed around the outer periphery of the methanol atomizing nozzle 310, and the multiple second outlets 122 are all provided with... The first outlets 121 are distributed around the outer periphery of the swirl vane 120 and around the first outlets 121. The first outlets 121 are directed to the axis of the methanol atomizing nozzle 310, that is, the air outlet direction of the first outlet 121 is at an acute angle to the axis extension direction of the methanol atomizing nozzle 310. When the second outlet 122 and the methanol atomizing nozzle 310 are projected onto the set plane a, the axis extension direction of the second outlet 122 is at an acute angle to the axis extension direction of the methanol atomizing nozzle 310. The set plane a is parallel to or coincides with the axis of the methanol atomizing nozzle 310. This configuration ensures that the combustion-supporting air output from the first outlet 121 is reliably cross-mixed with the methanol mist sprayed from the methanol atomizing nozzle 310; at the same time, the air blown out from the second outlet 122 forms a spiral flow, which can achieve secondary mixing with the unburned methanol by utilizing the combustion-supporting air output from the second outlet 122, thereby ensuring the completeness of methanol combustion; moreover, the second outlet 122 is located at the outer periphery of the swirl vane 120, and the air is close to the outer periphery when it is discharged, which can also reduce the temperature of the cavity sleeve located in the second housing 100.
[0063] Optionally, the angle between the air outlet direction of the first outlet 121 and the axial extension direction of the methanol atomizing nozzle 310 is 10 to 20°, such as 10°, 12°, 15°, 17°, 20°, etc., without specific limitation.
[0064] In this embodiment, the angle α between the air outlet direction of the first outlet 121 and the axial extension direction of the methanol atomizing nozzle 310 is 15°, and the angles between the air outlet directions of the plurality of first outlets 121 and the axial extension direction of the methanol atomizing nozzle 310 are the same. Of course, in other embodiments, the angles between the air outlet directions of the plurality of first outlets 121 and the axial extension direction of the methanol atomizing nozzle 310 may be different, and no specific limitation is made here.
[0065] Optionally, the multiple first exits 121 are distributed in multiple concentric circles, such as two, three, or four concentric circles; or in a single circle, etc., without specific limitations.
[0066] Optionally, when the second outlet 122 and the methanol atomizing nozzle 310 are projected onto the set plane a, the angle between the axial extension direction of the second outlet 122 and the axial extension direction of the methanol atomizing nozzle 310 is 15 to 45°, for example: 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc., which are not specifically limited here.
[0067] In this embodiment, when the second outlet 122 and the methanol atomizing nozzle 310 are projected onto the set plane a, the angle β between the axial extension direction of the second outlet 122 and the axial extension direction of the methanol atomizing nozzle 310 is 15°, and the tilt angles of the multiple second outlets 122 are the same. Of course, in other embodiments, the tilt angles of the multiple second outlets 122 may be different, which is not specifically limited here.
[0068] It should be noted that the inclination of the second outlet 122 extends along the outer periphery of the swirl vane 120, that is, the distance from any point on the central axis of the second outlet 122 to the axis of the methanol atomizing nozzle 310 is equal.
[0069] Please refer to Figure 3 In this embodiment, a filter 320 is installed inside the compressed air pipeline 300, and the filter 320 is distributed close to the methanol atomizing nozzle 310; this arrangement allows the filter 320 to filter out impurities and ensure the cleanliness of methanol combustion.
[0070] Please refer to Figure 2 In this embodiment, a flame arrester 230 is connected to the end of the Brown gas pipeline 200 away from the Brown gas nozzle 210, and the flame arrester 230 is located on the side of the threaded part 220 adjacent to the end cap 110 that faces away from the end cap 110. The flame arrester 230 can prevent Brown gas backfire and improve safety.
[0071] Please refer to Figure 8 and Figure 9 The methanol burner 010 of this embodiment also includes an ignition electrode 510, which is assembled in the housing 100 and extends from the first end. Specifically, the two ends of the ignition electrode 510 pass through the end cap 110 and the swirl vane 120, and the ignition end of the ignition electrode 510 extends from the swirl vane 120 into the air duct 101. The ignition electrode 510 is used to ignite the Brown gas output from the Brown gas nozzle 210.
[0072] Please refer to Figure 8 and Figure 9The methanol burner 010 in this embodiment also includes a flame detector 520, which is mounted on the housing 100 and extends from the first end. Specifically, the two ends of the flame detector 520 pass through the end cover 110 and the swirl vane 120, and the detection end of the flame detector 520 extends from the swirl vane 120 into the air duct 101. The flame detector 520 is used to detect whether Brown gas and methanol are successfully ignited.
[0073] The process of methanol combustion in the methanol burner 010 of this embodiment includes:
[0074] Combustion air is introduced through combustion air inlet 131 to maintain air circulation within the casing 100; Brown gas is introduced into Brown gas pipe 200 and ignited by ignition electrode 510 from Brown gas nozzle 210; compressed air is then introduced into compressed air pipe 300 and methanol is introduced into methanol pipe 400 to atomize methanol and spray it out from methanol atomizing nozzle 310. The atomized methanol gas mixes with the combustion air output from combustion air outlet and is then ignited by Brown gas flame.
[0075] In summary, the methanol burner 010 of this invention can be used in a methanol combustion system. The methanol burner 010 enables methanol to burn efficiently and ensures complete combustion, improving the problem of incomplete combustion of methanol and reducing carbon emissions.
[0076] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
