Description

Technical Field

[0001] This invention belongs to the field of combustion equipment technology, specifically a plasma-assisted methanol combustion torch. Background Technology

[0002] The torch is a symbol of the Games, representing the flame that burned throughout the ancient Games. Modern torches are designed to burn brightly and reliably under various conditions, including wind, rain, and different altitudes.

[0003] Traditional torches mostly use fossil fuels as energy sources, which result in low combustion efficiency, high pollutant emissions, and unstable combustion in extreme environments. During the combustion process, the torch mainly relies on oxygen from the air for combustion. Under extreme environmental conditions, traditional air oxygen supply methods are difficult to meet the needs of stable combustion, and the flame will go out due to insufficient oxygen.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] Example 1, refer to Figure 1-8 Plasma-assisted methanol combustion torch, including:

[0032] The flare casing 1 is equipped with a combustion chamber 2;

[0033] Combustion mechanism 3 is located inside torch housing 1. Combustion mechanism 3 includes fuel storage 301, gas pipeline 302, flame outlet component, flame channel 303, plasma generator 304 and ignition device 305. Fuel storage 301 is installed at the bottom of the inner wall of torch housing 1. One end of gas pipeline 302 is installed at the output end of fuel storage 301. Flame outlet component is installed on gas pipeline 302. Flame channel 303 is fixedly installed on the inner wall of torch housing 1. Plasma generator 304 is installed on one side of the inner wall of combustion chamber 2. Ignition device 305 is installed on one side of the inner wall of combustion chamber 2.

[0034] The oxygen supply mechanism 4 is located inside the combustion chamber 2. The oxygen supply mechanism 4 includes multiple air inlets 401, a mixing frame 402, multiple sets of air intake components, oxygen supply components, and mixing components. Each air inlet 401 is equidistantly opened on the outer wall of the torch shell 1 along the circumferential direction. The mixing frame 402 is fixedly sleeved on the outer wall of the flame channel 303. Each set of air intake components is equidistantly arranged on the mixing frame 402. The oxygen supply components are located inside the mixing frame 402, and the mixing components are located on the mixing frame 402.

[0035] In this embodiment: the flare shell 1 is made of high-temperature resistant lightweight carbon fiber composite material, ensuring the flare's lightness and durability. The combustion chamber 2 is located inside the flare shell 1 and is used to contain the combustion reaction of methanol fuel and oxygen. Through the combustion mechanism 3, methanol is used as its main fuel. Combined with plasma-assisted combustion, it can ensure the generation of a consistent and efficient flame. Compared with traditional hydrocarbon fuels, using green methanol, a renewable and clean fuel, can reduce carbon emissions. Methanol is stored in the fuel storage tank 301 and supplied to the combustion chamber 2 by the controlled delivery system on the fuel storage tank 301 and the gas pipeline 302. High-energy plasma is generated by the plasma generator 304, which can promote the chemical reaction between methanol and oxygen, improve combustion efficiency, and generate a stable high-temperature flame. The plasma generator 304 consists of electrodes located in the combustion chamber 2 and connected to a high-voltage power supply. This power supply generates a plasma arc to help decompose methanol molecules and initiate combustion. The voltage and current are regulated by electronic circuitry to maintain a consistent plasma arc. The plasma is activated by an ignition device 305 using a reliable piezoelectric or electronic igniter. An electric arc ignites the mixture of methanol fuel and plasma. Methanol is safer than traditional fuel oil, as it contains no dust, sulfur, or nitro compounds. Fuel oil and natural gas can significantly reduce air pollution and smog. Burning methanol reduces carbon emissions by more than 15% compared to fuel oil. Plasma assistance promotes complete combustion of methanol, reducing the production of harmful pollutants such as methanol, formaldehyde, and formic acid, achieving clean and efficient combustion. The oxygen supply mechanism 4 ensures sufficient oxygen is provided to the combustion chamber 2 under various conditions, making combustion more complete and thorough, preventing incomplete combustion and the generation of harmful gases, and improving the efficiency of methanol combustion. To ensure combustion stability and prevent flame extinguishing due to insufficient oxygen, the mixing frame 402 has multiple exhaust pipes on its inner wall, which extend into the flame channel 303. This allows the mixture of air and pure oxygen to enter the flame channel 303 and the combustion chamber 2. Air enters the torch housing 1 through the air inlet 401. Each set of air inlet components allows air to enter the mixing frame 402, where it mixes with pure oxygen to form an oxygen-rich mixture. This provides sufficient oxygen and prevents flame extinguishing due to insufficient oxygen. Pure oxygen is also provided through the oxygen supply component.

[0036] Specifically, the flame-emitting components include a main flame gas pipe 306, multiple gas holes 307, and a flame nozzle 308. The main flame gas pipe 306 is connected to the gas pipeline 302. Each gas hole 307 is equidistantly opened on one side of the outer wall of the main flame gas pipe 306. The flame nozzle 308 is connected to the gas pipeline 302.

[0037] In this embodiment: the main flame gas pipe 306 is fixedly connected to the gas pipe 302. The main flame gas pipe 306 is used to transport methanol to the combustion chamber 2, which can spray the fuel in the form of a fine jet. After mixing with the surrounding air, it forms a combustible mixture. The gas hole 307 is located at the bend of the main flame gas pipe 306, which can ensure that the fuel is evenly distributed in the combustion chamber 2, improving combustion efficiency and stability. The flame can be sprayed out through the flame nozzle 308. The internal circuit principle of the flame nozzle 308 is common knowledge to those skilled in the art and will not be described in detail here.

[0038] Specifically, each air intake component includes an air intake pipe 403, a filter screen 404, a filter element 405, and a small fan 406. The air intake pipe 403 is fixedly installed on the outer wall of the mixing frame 402, the filter screen 404 is fixedly installed on one end of the air intake pipe 403, the filter element 405 is installed on the inner wall of the air intake pipe 403, and the small fan 406 is installed on the inner wall of the air intake pipe 403.

[0039] In this implementation scheme: air entering the flare housing 1 is introduced into the mixing frame 402 through the air inlet pipe 403. The air entering the mixing frame 402 is filtered through the filter screen 404 and the filter element 405, effectively removing impurities and moisture from the air, improving the plasma generation efficiency and methanol combustion effect, so that the flare can maintain a stable combustion state even in extreme weather or polluted environments. The filter element 405 is a HEPA filter or an activated carbon layer, which can effectively remove dust, pollen, bacteria, viruses and harmful gases from the air. The filter screen 404 can filter particulate matter and impurities from the air to ensure the quality of the air entering the flare. The small fan 406 can introduce external air into the flare and make the air enter the mixing frame 402.

[0040] Specifically, the oxygen supply components include an oxygen storage tank 407, an air pump 408, an oxygen sensor 409, and an oxygen supply assembly. The oxygen storage tank 407 is installed on the inner wall of the flare housing 1, the air pump 408 is installed on the inner wall of the flare housing 1, the input end of the air pump 408 is connected to the output end of the oxygen storage tank 407 through a pipe, the oxygen sensor 409 is installed on the inner wall of the combustion chamber 2, and the oxygen supply assembly is located on the air pump 408.

[0041] In this implementation scheme: Oxygen storage tank 407 is used to store oxygen. An air pump 408 draws oxygen from the oxygen storage tank 407 to the mixing frame 402, mixing the oxygen with air to prevent insufficient oxygen in the combustion chamber 2 and incomplete combustion. The oxygen storage tank 407 is equipped with an oxygen flow meter and an oxygen pressure reducing valve. The oxygen flow meter accurately measures and controls the oxygen supply to ensure the oxygen demand during methanol combustion is met. The oxygen pressure reducing valve adjusts the oxygen pressure to a suitable range for flare combustion. An oxygen sensor 409 monitors the oxygen concentration level in the combustion chamber 2 in real time, facilitating precise control of the oxygen-to-methanol ratio and preventing flame extinguishing or incomplete combustion due to excessively low oxygen concentration, which increases safety risks. The internal circuit principles of the oxygen storage tank 407, air pump 408, and oxygen sensor 409 are common knowledge to those skilled in the art and will not be described in detail here. Their models can be selected according to actual usage.

[0042] Specifically, the oxygen supply assembly includes an oxygen tube 410 and multiple oxygen holes 411. The oxygen tube 410 is installed at the output end of the air pump 408, and each oxygen hole 411 is equidistantly opened on the outer wall of the oxygen tube 410.

[0043] In this embodiment: the bent part of the oxygen pipe 410 is located inside the mixing frame 402. The oxygen in the oxygen storage tank 407 is drawn into the oxygen pipe 410 by the air pump 408. The oxygen enters the mixing frame 402 through the oxygen hole 411 to meet the oxygen demand in the methanol combustion process.

[0044] Specifically, the mixing component includes a first mounting bracket 412, a second mounting bracket 413, a drive assembly, a cleaning assembly, and a mixing assembly. The first mounting bracket 412 is fixedly disposed on one side of the inner wall of the torch housing 1, the second mounting bracket 413 is fixedly disposed on the bottom of the inner wall of the mixing frame 402, the drive assembly is disposed on the second mounting bracket 413, the cleaning assembly is disposed on the mixing frame 402, and the mixing assembly is disposed inside the mixing frame 402.

[0045] In this embodiment: the first mounting bracket 412 is used for the installation and placement of the rotating shaft 420, and the second mounting bracket 413 is used for the installation and placement of the rotating shaft 423. The drive assembly can simultaneously drive the cleaning assembly and the mixing assembly, so that the cleaning assembly cleans the surface of the filter screen 404 to prevent the filtered impurities and particles from clogging the filter screen 404 and affecting the air entering the mixing frame 402. The mixing assembly can promote the gas flow in the mixing frame 402 and enhance the diffusion and mixing between air and pure oxygen molecules.

[0046] Specifically, each mixing component includes multiple mixing shafts 414, multiple fan blades 415, multiple first pinions 416, and a first gear 417. Each mixing shaft 414 is rotatably embedded in the bottom of the inner wall of the mixing frame 402. Each fan blade 415 is movably sleeved on the outer wall of the mixing shaft 414. Each first pinion 416 is fixedly sleeved on the outer wall of the mixing shaft 414 near the bottom edge. Each first pinion 416 meshes with the first gear 417. The first gear 417 is rotatably embedded in the inner wall of the mixing frame 402.

[0047] In this implementation scheme: the mixing shaft 414 on each first small gear 416 is synchronously driven by the first large gear 417 to rotate within the mixing frame 402, causing the fan blade 415 to rotate. This promotes gas flow within the mixing frame 402, making the external air and oxygen mix evenly and resulting in a more uniform oxygen concentration. This helps to create a more stable and efficient combustion environment within the combustion chamber 2, reducing incomplete combustion in certain areas and thus improving overall combustion efficiency.

[0048] Specifically, the cleaning assembly includes a second large gear 418, a second small gear 419, a rotating shaft 420, and multiple brush rods 421. The second large gear 418 is rotatably embedded in the outer wall of the mixing frame 402, the second small gear 419 is fixedly sleeved on the outer wall of the rotating shaft 420, and the second small gear 419 meshes with the second large gear 418. The rotating shaft 420 is rotatably embedded in the inner wall of the first mounting bracket 412, and each of the multiple brush rods 421 is fixedly set on the outer wall of the second large gear 418.

[0049] In this embodiment: the rotating shaft 420 drives the second small gear 419 to rotate on the first mounting bracket 412, which in turn drives the second large gear 418 to rotate, causing each brush rod 421 to move. The brush rod 421 can clean the impurities attached to the surface of the filter screen 404, preventing particles and impurities from clogging the filter screen 404.

[0050] Specifically, the drive assembly includes a rotary motor 422, a rotary shaft 423, two first bevel gears 424, a second bevel gear 425, and a third bevel gear 426. The rotary motor 422 is bolted to the inner wall of the torch housing 1. The rotary shaft 423 is fixedly disposed at the output end of the rotary motor 422 and is rotatably embedded in the inner wall of the second mounting bracket 413. Each first bevel gear 424 is fixedly sleeved on the outer wall of the rotary shaft 423. The second bevel gear 425 is fixedly sleeved on the outer wall of the rotary shaft 420. The third bevel gear 426 is fixedly sleeved on the outer wall of one of the mixing shafts 414. One of the first bevel gears 424 meshes with the second bevel gear 425, and the other first bevel gear 424 meshes with the third bevel gear 426.

[0051] In this implementation scheme: when the rotating motor 422 is powered on, it drives the rotating shaft 423 to rotate, which in turn causes the two first bevel gears 424 to rotate, which in turn causes the second bevel gear 425 to drive the rotating shaft 420 to rotate, and the third bevel gear 426 to drive one of the mixing shafts 414 to rotate. The power for the rotating motor 422 and the small fan 406 comes from an external power source, and they should be electrically connected to the external power source. The internal circuit principle and structure are common knowledge to those skilled in the art and will not be described in detail here. The model can be selected according to the actual use.

[0052] Specifically, a metal mesh 5 is fixedly installed on the top of the outer wall of the torch shell 1.

[0053] In this implementation plan: the metal mesh 5 can isolate the flame from the external environment, which helps to improve the wind resistance of the torch.

[0054] In operation, the fuel valve on the fuel reservoir 301 is first opened, allowing fuel to enter the main flame gas pipe 306 through the gas pipe 302, then into the combustion chamber 2 through the gas port 307, and finally into the flame channel 303 through the flame nozzle 308. Simultaneously, external air enters the torch housing 1 through the air inlet 401, and is drawn into the air inlet pipe 403 by the small fan 406. The air entering the mixing frame 402 is filtered by the filter screen 404 and the filter element 405, effectively removing impurities and moisture from the air, improving the plasma generation efficiency and methanol combustion effect, and enabling the torch to maintain a stable combustion state even in extreme weather or polluted environments. The oxygen sensor 409 monitors the oxygen concentration in the combustion chamber 2 in real time. When the concentration is lower than a set threshold, the air pump 408 is triggered to operate, causing the air pump 408 to draw oxygen from the oxygen storage tank 407 into the oxygen pipe 410, which then enters the mixing frame 402 through the oxygen port 411. At the same time, the rotating motor 422 drives the rotating shaft 423 to rotate, causing the two first bevel gears 424 to rotate. The second bevel gear 425 drives the rotating shaft 420 to rotate, which in turn drives the second pinion 419 to rotate on the first mounting bracket 412. This drives the second large gear 418 to rotate, causing each brush rod 421 to move. The brush rods 421 can clean the impurities attached to the surface of the filter screen 404, preventing particles and impurities from clogging the filter screen 404. At the same time, the third bevel gear 426 drives one of the mixing shafts 414 to rotate, which in turn drives the first large gear 417 to rotate within the mixing frame 402, causing the other mixing shafts 414 to rotate within the mixing frame 402. The mixing shafts 414 drive the fan blades 415 to rotate, which promotes gas flow within the mixing frame 402 and enhances the diffusion and mixing between air and pure oxygen molecules. The mixed gas enters the flame channel 303 and the combustion chamber 2 through the exhaust pipe and mixes with methanol fuel. Then, the ignition device 305 is triggered, generating a plasma arc that ignites the mixture of methanol fuel and plasma. The plasma-assisted combustion process produces a stable high-temperature flame, which is ejected through the flame nozzle 308.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
