Description

Technical Field

[0001] This invention relates to the field of combustion device technology, and more specifically, to a water-based fuel plasma composite combustion torch. Background Technology

[0002] Water-based fuel is obtained by electrolyzing water. Common water-based fuel equipment can be divided into two categories: one is a water electrolysis high-purity hydrogen generator, and the other is a water electrolysis hydrogen-oxygen generator. An existing invention patent with publication number CN1878443A discloses a plasma beam generator. Its advantages include a robust mechanical structure connecting the ignition button to the cathode tail and the cathode head to the cathode rod, and flexible and convenient adjustment of the arc by rotating the threaded ignition button. This is a 2KW-3KW level water vapor plasma emergency miniature cutter device, with a flame nozzle lifespan in the minute range.

[0050] Working principle:

[0051] In actual use, provided the composite combustion torch is reliably grounded, water-based fuel is injected into the interlayer cavity 2 through the fuel input pipe 27. Part of the water-based fuel liquid enters the cooling chamber 5 through the first steam channel 6, and most of it flows into the position of the water suction sleeve 18 through the liquid delivery hole 8. After the water suction sleeve 18 is full of water-based fuel liquid, part of the overflowing water-based fuel liquid flows into the arc chamber 7 through the second steam channel 20 and the steam delivery hole 21 in sequence, and part of it flows into the connecting rod center hole 30 of the electrode connecting rod 10 through the first protection pipe connecting hole 16 and the inlet hole 12 in sequence. The water-based fuel liquid flows into the hollow electrode head 11 through the connecting rod center hole 30 and enters the arc chamber 7. Part of the water-based fuel liquid enters the central steam collection hole 14 of the insulating electrode protection pipe 13 through the second protection pipe connecting hole 17. This part of the liquid then enters the ceramic support center hole 15 from the central steam collection hole 14 and flows into the arc chamber 7.

[0052] After the water-based fuel is filled and begins to overflow from nozzle 3, the multiphase plasma power supply is turned on. After the connecting wire 29 is energized, the arc is started. The water-based fuel in the arc chamber 7 is rapidly vaporized and ionized by the arc and ejected from nozzle 3 in the form of a plasma flame, with a temperature of 8000-10000℃.

[0053] The heat in the arc chamber 7 increases rapidly and heats the nozzle 3. At the same time, the heat is transferred to the heat-conducting shell 1. After the temperature of the nozzle 3 rises, the temperature of the cooling chamber 5 increases and heats the water-based fuel, causing it to vaporize. The vaporized water-based fuel enters the position of the water suction sleeve 18 through the first steam channel 6. At the same time, the temperature of the heat-conducting shell 1 increases and heats the water suction sleeve 18, causing the water-based fuel adsorbed on the water suction sleeve 18 to vaporize. After the water-based fuel is vaporized, the gas expands and enters the heat-conducting outer shell 1 through the liquid delivery hole 8. The vaporized water-based fuel then passes through the channels described above (in sequence, it enters the arc chamber 7 through the second steam channel 20 and the steam delivery hole 21; in sequence, it enters the arc chamber 7 through the first protective pipe connecting hole 16, the inlet hole 12, and the connecting rod center hole 30; in sequence, it enters the arc chamber 7 through the second protective pipe connecting hole 17, the central steam collection hole 14, and the ceramic support center hole 15) and finally flows into the plasma arc chamber 7. The water-based fuel vapor in the arc chamber 7 is rapidly ionized by the electric arc and ejected from the nozzle 3, and the cycle repeats continuously.

[0054] For example, water vapor molecules exist in a highly plasma state in a three-phase or multi-phase high-voltage high-frequency alternating electric field. The nuclei of hydrogen isotopes deuterium and tritium partially collide and fuse to release nuclear energy. After leaving the electric field region, oxygen atoms combine with hydrogen atoms to release chemical energy, producing a flame column of 8000-10000℃.

[0055] For example, water-soluble organic solutions and water vapor-soluble organic compounds also exhibit a highly plasma state in a three-phase or multi-phase high-voltage high-frequency alternating electric field. In addition to the deuterium and tritium nuclei in the ionized hydrogen elements colliding and fusing to release nuclear energy, the ionized carbon elements, after leaving the electric field region, rapidly combine and burn with oxygen in a high-temperature region of 8000-10000℃, simultaneously releasing chemical energy.

[0056] Therefore, this application can generate a flame column of 8000-10000℃ by releasing chemical energy through chemical combustion of water-based fuel in a highly plasma state in a three-phase or multi-phase high-voltage high-frequency alternating electric field, which can be applied to industrial use.

[0057] In this embodiment, if an external water vapor source is available, it can be directly connected to the fuel inlet pipe 27 for use. The water-based fuel can be a mixture of water and alcoholic organic compounds in any proportion, or it can be an emulsion aqueous solution, etc.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.

[0059] Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
