[0002] With the development of the domestic petroleum processing industry, the demand for improved oil quality has increased significantly. Following the successful development of this project, the team studied the layout of the hot water pipes in a double-layer heating furnace to maintain heat and improve heating efficiency. They also developed a long-lasting, stable heating device that reacts with hydrogen under stable heating conditions, effectively removing harmful substances from the gasoline.

[0003] Catalytic cracking is a petroleum refining process that involves the cracking of heavy oil under the action of heat and a catalyst, converting it into cracked gas, gasoline, and diesel. Gasoline hydrorefining typically requires a heating furnace, but existing furnaces have poor heat retention. This prevents the gasoline within the furnace from being fully heated, resulting in uneven heating and poor catalytic performance. Furthermore, when hydrogen is injected, localized injection leads to uneven contact between the gasoline and hydrogen, affecting gasoline decomposition. Consequently, these furnaces present shortcomings. Utility Model Content

[0025] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0026] like Figure 1-Figure 5 As shown, a heating furnace for catalytic decomposition of gasoline according to an embodiment of the present application includes:

[0027] The outer furnace body 1 is fixedly sleeved with the inner furnace body 8 inside the outer furnace body 1. The inner furnace body 8 and the outer furnace body 1 are set as an integrated structure, and a gap is set between the outer furnace body 1 and the inner furnace body 8 to facilitate the placement of the externally coiled hot water pipe 7. The top of the outer furnace body 1 and the inner furnace body 8 are sealed and installed with a common upper sealing cover 2. The upper part of the upper sealing cover 2 is sealed and connected with a feeding port 4 and a vacuum port 5. The feeding port 4 can be used to add gasoline to the inner furnace body 8, and the vacuum port 5 can be used to evacuate the inner furnace body 8. The upper part of the upper sealing cover 2 is fixed. A driving motor 3 is installed, and a heating component is provided inside the inner furnace body 8. The heating component includes a heating frame 11. The top of the heating frame 11 is fixedly connected to the output shaft of the driving motor 3 through a heat-insulating material. The heat-insulating material can be made of stainless steel. Stainless steel profiles are also a commonly used heat-insulating metal profile. It has the advantages of high temperature resistance, good corrosion resistance, and strong heat resistance. It is often used for heat insulation in high temperature environments. This avoids the heating frame 11 from damaging the driving motor 3 during the heating process. The side walls of the heating frame 11 are symmetrically opened. A guide groove 12 is provided, and the heating frame 11 is driven by the driving motor 3 to rotate in the inner furnace body 8, so that the heating frame 11 can fully and evenly heat the gasoline, avoiding uneven heating, where part of the gasoline has been decomposed and reacted while part is still being heated. The guide groove 12 is provided on the side wall of the heating frame 11. When the heating frame 11 rotates, the oil will pass through the guide groove 12, increasing the speed of the oil splitting and fusing hydrogen. When the heating frame 11 rotates, the guide groove 12 can increase the contact area with the oil, resulting in better heating effect and more sufficient and uniform heating. The rotation of the heating frame 11 needs to be determined according to the direction of the guide groove 12, avoiding the back of the heating frame 11 directly splitting the oil for rotating and heating uniformly, which will increase resistance, not only increasing energy consumption, but also reducing the life of the driving motor 3. If the internal oil does not need to be heated, when other auxiliary materials are added to the inside, it can also be stirred and evenly mixed by the rotation of the heating frame 11, achieving multiple uses. And because the guide groove is provided, the mixing will be more uniform.

[0028] A hydrogen pipeline 6 is fixedly installed on the outside of the outer furnace body 1. The inner end of the hydrogen pipeline 6 is arranged in conjunction with the inner furnace body 8. The hydrogen pipeline 6 surrounds the outer side of the outer furnace body 1. After the hydrogen pipeline 6 is filled with hydrogen, the pressure in the hydrogen pipeline 6 is uniform. The annular arrangement can make the hydrogen injection more uniform. The inner side of the hydrogen pipeline 6 passes through the outer furnace body 1 through a connecting pipe and extends inward. The extended end is connected to the electronically controlled injection valve 10 to inject hydrogen into the inner furnace body 8.

[0029] The outside of the inner furnace body 8 is sheathed with a hot water pipe 7, one end of which can be connected to a circulation pump to increase the hot water circulation inside the hot water pipe 7 and increase the insulation and auxiliary heating effect. The two ends of the hot water pipe 7 are both through the outer wall of the outer furnace body 1. The hot water pipe 7 transfers heat to the inside through the side wall of the inner furnace body 8. The hot water pipe 7 can keep the inside of the inner furnace body 8 hot, improve the heating efficiency, and effectively remove harmful substances in gasoline. The inner bottom of the inner furnace body 8 is set to an inclined structure to facilitate the discharge of gasoline with impurities removed, avoid internal residues, and reduce cleaning troubles. The top of the inner furnace body 8 is annularly and equidistantly opened with sealing holes 9, and the sealing holes 9 are inclined toward the center An electronically controlled injection valve 10 is sealed and installed in the sealing hole 9. The access end of the electronically controlled injection valve 10 is connected to the internal connecting pipe of the hydrogen pipeline 6. The injection end of the electronically controlled injection valve 10 is facing the interior of the inner furnace body 8. Multiple electronically controlled injection valves 10 are in a ring-shaped manner to inject hydrogen into the gasoline inside the inner furnace body 8. The injection is more uniform and sufficient, thereby increasing the efficiency of the catalytic decomposition of gasoline. The electronically controlled injection valve 10 is set on the inner furnace body 8 at a downward angle of 15°, so that it can be evenly sprayed on the surface of the petroleum. The electronically controlled injection valve 10 adopts a valve that can inject mist-like particulate gas.

[0030] like Figure 1-Figure 2 and Figure 3-Figure 5 As shown, a sealing groove 13 is provided on the top of the inner furnace body 8, and the sealing groove 13 is sealingly connected to the sealing ring 14. The bottom of the upper sealing cover 2 is fixedly connected with the sealing ring 14, and the sealing ring 14 can be inserted into the sealing groove 13 in a sealing manner, thereby forming a sealed space in the inner furnace body 8, and when the upper sealing cover 2 is installed, it can be conveniently positioned and fixed. After the sealing ring 14 is inserted into the sealing groove 13, the inner furnace body 8 and the outer furnace body 1 are completely isolated, thereby avoiding the exhaust gas generated by the catalytic reaction of petroleum in the inner furnace body 8 from being discharged to the outside, thereby avoiding exhaust gas leakage and increasing the safety of the operation site.

[0031] Specifically, the working principle of the heating furnace for catalytic decomposition of gasoline is as follows: petroleum is added into the inner furnace body 8 through the feeding port, and then it is sealed, and then the internal air is extracted through the vacuum port 5 to form a vacuum, and then the heating frame 11 is driven by the driving motor 3 to rotate in the inner furnace body 8, so that the heating frame 11 can fully and evenly heat the gasoline to avoid uneven heating. The side wall of the heating frame 11 is provided with a guide groove 12. When the heating frame 11 rotates, it can increase the contact area with the petroleum, and the heating effect is better. A plurality of electronically controlled injection valves 10 are sealed and installed in a ring-shaped manner at the top of the inner furnace body 8 to inject hydrogen, and the injection is more uniform and sufficient, thereby increasing the efficiency of the catalytic decomposition of gasoline. The hot water pipe 7 is tightly coiled around the outside of the inner furnace body 8. The hot water pipe 7 will transfer heat to the side wall of the inner furnace body 8, and the entire inner furnace body 8 is insulated and heated, thereby improving the heating efficiency and effectively removing harmful substances in gasoline.
