It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

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

[0032] A torch housing 1 having a combustion chamber 2;

[0033] The combustion mechanism 3 is arranged in the torch housing 1, and the combustion mechanism 3 includes a fuel storage tank 301, a gas pipeline 302, a flame outlet component, a flame channel 303, a plasma generator 304 and an ignition device 305. The fuel storage tank 301 is installed at the bottom of the inner wall of the torch housing 1, one end of the gas pipeline 302 is installed at the output end of the fuel storage tank 301, the flame outlet component is arranged on the gas pipeline 302, the flame channel 303 is fixedly arranged on the inner wall of the torch housing 1, the plasma generator 304 is installed on one side of the inner wall of the combustion chamber 2, and the ignition device 305 is installed on one side of the inner wall of the combustion chamber 2;

[0034] The oxygen supply mechanism 4 is arranged in the combustion chamber 2, and includes a plurality of air inlet holes 401, a mixing frame 402, a plurality of groups of air inlet components, oxygen supply components and mixing components. Each air inlet hole 401 is equidistantly opened on the outer wall of the torch housing 1 along the circumferential direction, the mixing frame 402 is fixedly sleeved on the outer wall of the flame channel 303, each group of air inlet components is equidistantly arranged on the mixing frame 402, the oxygen supply component is arranged in the mixing frame 402, and the mixing component is arranged on the mixing frame 402.

[0035] In this embodiment: the torch housing 1 is made of a high-temperature resistant lightweight carbon fiber composite material to ensure the lightness and durability of the torch. The combustion chamber 2 is arranged inside the torch housing 1 to accommodate the combustion reaction of a mixture of methanol fuel and oxygen. Through the combustion mechanism 3, methanol is used as its main fuel, combined with plasma-assisted combustion, to ensure the generation of consistent and efficient flames. Compared with traditional hydrocarbon fuels, the use of green methanol, a renewable clean fuel, can reduce carbon emissions. The fuel storage 301 is used to store methanol. The methanol is supplied to the combustion chamber 2 by a controlled delivery system on the fuel storage 301 and a gas pipeline 302. A high-energy plasma is generated through a 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 is composed of electrodes located in the combustion chamber 2 and is connected to a high-voltage power supply, which generates a plasma arc to help decompose methanol molecules and initiate combustion. The voltage and current are adjusted by an electronic circuit to maintain a consistent plasma arc. The ignition device 305 uses a reliable piezoelectric or electronic igniter to start the plasma The arc ignites the mixture of methanol fuel and plasma. Methanol is safer than traditional fuel. Methanol as a fuel does not contain dust, sulfur and nitro compounds. Fuel oil and natural gas can significantly reduce air pollution and haze. Burning methanol reduces carbon emissions by more than 15% compared to fuel oil. Plasma assistance can promote the complete combustion of methanol, reduce the production of harmful pollution such as methanol, formaldehyde, formic acid, etc., and achieve clean and efficient. Through the oxygen supply mechanism 4, it is ensured that sufficient oxygen can be provided to the combustion chamber 2 in various environments, so that the combustion is more complete and thorough, and harmful gases are prevented from being produced by incomplete combustion, thereby improving the efficiency of methanol. In order to ensure combustion stability and prevent the flame from being extinguished due to lack of oxygen, a plurality of air outlet pipes are provided on the inner wall of the mixing frame 402, and the air outlet pipes extend to the interior of the flame channel 303, so that the gas mixed with air and pure oxygen can enter the flame channel 303 and the combustion chamber 2. The air can enter the torch housing 1 through the air inlet hole 401, and the air can enter the mixing frame 402 through each set of air inlet components. The air and pure oxygen are mixed to form an oxygen-rich mixed gas by cooperating with the mixing components, thereby providing sufficient oxygen to prevent the flame from being extinguished due to lack of oxygen. Pure oxygen can be provided through the oxygen supply components.

The internal circuit principle structure of oxygen storage tank 407, air pump 408 and oxygen sensor 409 belongs to the common knowledge of technicians in this field, and will not be introduced in detail here.

The driving assembly can simultaneously drive the cleaning assembly and the mixing assembly, so that the cleaning assembly cleans the surface of the filter 404 to prevent the filtered impurities and particulate matter from clogging the filter 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 the air and the pure oxygen molecules.

[0046] Specifically, the mixing components include multiple mixing shafts 414, multiple fan blades 415, multiple first small gears 416 and a first large gear 417.

[0047] In this embodiment: the mixing shaft 414 on each first small gear 416 is synchronously driven to rotate in the mixing frame 402 by the first large gear 417, so that the fan blades 415 rotate, which can promote the flow of gas in the mixing frame 402, mix the external air and oxygen evenly, make the oxygen concentration more uniform, and help to form a more stable and efficient combustion environment in the combustion chamber 2, reduce the situation of local incomplete combustion, and thus improve the overall combustion efficiency.

[0048] Specifically, the cleaning assembly includes a second large gear 418, a second small gear 419, a rotating shaft 420 and a plurality of brush rods 421.

At the same time, external air enters the torch housing 1 through the air inlet hole 401, and the small fan 406 introduces the external air into the air inlet pipe 403, and the air entering the mixing frame 402 is filtered through the filter 404 and the filter element 405, which effectively removes impurities and moisture in the air, improves the plasma generation efficiency and the combustion effect of methanol, so that the torch can maintain a stable combustion state in extreme weather or polluted environment. The oxygen sensor 409 monitors the oxygen concentration in the combustion chamber 2 in real time. When the concentration is lower than the set threshold, the air pump 408 is triggered to work, so that the air pump 408 draws the oxygen in the oxygen storage tank 407 into the oxygen pipe 410, and enters the mixing frame 402 through the oxygen hole 411.

The second bevel gear 425 is driven to drive the rotating shaft 420 to rotate, and the rotating shaft 420 drives the second small gear 419 to rotate on the first mounting frame 412, which can drive the second large gear 418 to rotate, so that each brush rod 421 moves, and the brush rod 421 can clean the impurities attached to the surface of the filter 404 to prevent the particles and impurities from clogging the filter 404. At the same time, the third bevel gear 426 is driven to drive one of the mixing shafts 414 to rotate, and the first large gear 417 is driven to rotate in the mixing frame 402, so that the other mixing shafts 414 rotate in the mixing frame 402. The mixing shaft 414 drives the fan blades 415 to rotate, which can promote the gas flow in the mixing frame 402 and enhance 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 outlet pipe and mixes with the methanol fuel. Then the ignition device 305 is triggered to generate a plasma arc to ignite the mixture of methanol fuel and plasma. The plasma-assisted combustion process generates a stable high-temperature flame, which is ejected through the flame nozzle 308.
