[0054] The center of the anode cap 10 has an opening with an inner diameter of not less than 10 mm, and it contacts the top end of the plasma torch shell and extends into the reforming cavity; the above opening is the top through hole.
[0055] The top of the high-voltage electrode 11 is in the shape of a frustum of a cone, and the tooth-shaped structure is used for heat dissipation; during use, the high-voltage electrode 11 does not contact the anode cap 10, and at the closest distance, the gap between the two is not less than 1 mm.
[0056] The insulating part 15 is made of alumina ceramic material, and the overall structure is a cylindrical shape with an outer diameter larger at both ends than in the middle, and it is coaxial with the high-voltage electrode 11, the anode cap 10, and the shell.

[0060] The reforming reaction chamber includes a reforming secondary reaction chamber 1, a synthesis gas outlet 2, a connecting flange, a feed inlet 4, an inner conduit 5, and a reforming primary reaction chamber 6; among them, the reforming primary reaction chamber 6, the reforming secondary reaction chamber 1, and the plasma torch are all sealed and connected using knife-edge flanges; a part of the inner conduit 5 is located in the reforming primary reaction chamber 6, and a part is located in the reforming secondary reaction chamber 1, and is fixed to the connecting flange 3 on the cavity body.

The plasma torch is used to generate a rotating sliding arc plasma for assisting diesel cracking and reforming, and the reforming reaction chamber is used for feeding reactants such as fuel, air, and water, and is the main place where the reaction occurs.
[0064] Connect the rotating sliding arc plasma torch to the reforming reaction chamber, and utilize the generated rotating sliding arc non-thermal plasma to feed and reform diesel inside the chamber. In this way, diesel undergoes cracking in the environment of non-equilibrium plasma with high temperature and high chemical activity, and partial oxidation reforming and steam reforming reactions occur, while releasing heat to form a high-temperature region in the reforming reaction chamber; the cracking products and reforming products further stay in the secondary reaction chamber 1 through the inner conduit 5 for secondary cracking and reforming, thereby realizing high-conversion reforming of diesel to produce hydrogen.
[0065] The connecting housing 8 is integrally formed by welding two hollow cylinders with different inner diameters. There are threads inside the lower cylinder with a smaller inner diameter for the adjustment and fixation of the electrode support rod 12 component; the high-voltage electrode 11 is screwed tightly to the head of the electrode support rod 12 through threads; the outside of the electrode support rod 12 is wrapped with ceramic material, that is, the insulating part 15, which is insulated from the outer shell; the anode cover 10 is placed at the upper end of the high-voltage electrode 11, maintaining a certain gap with the high-voltage electrode 11 and contacting the outer shell; the outer wall of the connecting sleeve 14 has threads for mating and fixing with the outer shell; the tail of the electrode support rod 12 is connected to the terminal 17, and the terminal 17 is connected to the high-voltage power supply to generate a rotating sliding arc.
[0066] The top of the high-voltage electrode 11 is in the shape of a frustum of a cone, and the lower tooth-shaped structure is used for heat dissipation.
[0067] During the design and installation process, the high-voltage electrode 11 and the anode cover 10 cannot be in contact, and at the closest distance, the gap between the two is not less than 1 mm to ensure normal discharge and the generated arc rotates in the reforming chamber with a certain height.
[0068] The middle concave part of the insulating part 15 is fixed by brazing with the sleeve, and the inner through hole has the same diameter as the electrode support rod 12 for the electrode support rod 12 to pass through.
[0069] The terminal 17, that is, the tail of the electrode support rod 12, is pressed tightly against the wire of the high-voltage power supply through nuts, washers, etc.
[0070] The syngas outlet 2 is located near the connecting flange of the reforming secondary reaction chamber 1; the feed port 4 is located at the upper part of the reforming primary reaction chamber 61, near the connecting flange with the secondary chamber, and is a pair of centrally symmetric pipe orifices with a diameter of 6 - 10 mm;
[0071] The pipe orifice position of the inner conduit 5 in the reforming secondary reaction chamber 1 needs to be higher than the outlet to ensure that the reactants have sufficient residence time in the chamber to fully react; at the same time, the position of the inner conduit 5 in the reforming primary reaction chamber 6 is lower than the feed port 4 to ensure that the reactants pass through the plasma region.
[0072] The inner surface of the feed inlet 4 is vertically tangent to the outer surface of the primary reforming reaction chamber 6, and the inner conduit 5, the primary reforming reaction chamber 6, and the secondary reforming reaction chamber 1, and the high-voltage electrode 11 are coaxial.
[0073] In the design and installation process, in order to obtain better use effects and improve the stability and operation convenience during installation and use, preferably, a syngas outlet 2 can be added according to the cavity pressure and the size of the syngas flow rate. Preferably, a plurality of outlets are arranged in a centrosymmetric structure. At the same time, considering the miniaturization and safety of the overall device, the maximum outer diameter of the sliding arc plasma-assisted diesel reforming device is set to 76 mm, the length is 780 mm, and the cavity wall thickness is not less than 2 mm. Among them, the reforming reaction chamber is set to 290 mm.
[0074] During the actual use process, the gas source is connected to the discharge gas nozzle 9, and the terminal 17 of the sliding arc plasma torch is connected to the high-voltage power supply wire. The diesel gas, water vapor, and air are mixed and then introduced into the cavity through the feed inlet 4.
[0075] During use, the overall device is placed vertically so that the incoming reactant gas flow reaches the periphery of the plasma region under the action of gravity.
[0076] The required reactant flow rate is determined by the diesel processing amount, the oxygen-carbon ratio, and the water-carbon ratio. The oxygen-carbon ratio is usually between 0.5 and 1.5, and the water-carbon ratio is between 1.6 and 2.6. To ensure the stable operation of the plasma, the discharge gas flow rate should be between 15 and 30 L / min, and the remaining gas is the carrier gas, which is mixed with the diesel gas and water vapor and enters the cavity. The products after diesel reforming are discharged from the outlet.
[0077] The reforming device of the present invention can realize the production of hydrogen-rich mixture by applying sliding arc plasma-assisted diesel reforming, avoiding problems such as the need to frequently replace the catalyst, short service life, and uneven reaction of the catalytic reformer, and achieving a high diesel conversion rate without adding any catalyst. The proposed device can withstand the high temperature generated by the reforming reaction, has high safety, can handle a large amount of diesel, and can achieve long-term stable operation.
[0078] The present invention connects the rotating sliding arc plasma torch with the reforming reaction chamber and uses the generated rotating sliding arc non-thermal plasma to feed and reform diesel inside the cavity.
[0079] In this way, diesel undergoes cracking in the environment of non-equilibrium plasma with high temperature and high chemical activity, and partial oxidation reforming and steam reforming reactions occur, while releasing heat to form a high-temperature region in the reforming reaction chamber. The cracking products and reforming products further stay in the secondary reaction chamber 1 through the inner conduit 5 for secondary cracking and reforming, thereby realizing the high-conversion reforming of diesel to produce hydrogen.
[0080] Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
