According to the relative boiling point difference of each component in the reaction product gas phase, the expander can recover extremely high-purity hydrogen from the reaction product gas phase, and the hydrogen is then stored in the gas cylinder system through the pressurizing device, reducing hydrogen consumption and energy consumption.

[0004] The reaction equipment provided by the above patent document passes hydrogen into the reaction tank through a distributor at the bottom of the reaction tank. Due to the low density of hydrogen, hydrogen will quickly float up in the reaction tank, resulting in a relatively low contact rate between the oil and hydrogen. In actual production, it is necessary to repeatedly recover the upper layer of hydrogen and repeatedly pressurize it into the reaction tank, resulting in low efficiency of oil hydrogenation treatment. Summary of the invention

[0005] The present invention provides a fuel reaction device and a reaction method, aiming to solve the problem in the related art that when the fuel is hydrogenated, the reaction efficiency between the oil and hydrogen is low due to the fast floating speed of hydrogen.

[0007] The air intake assembly includes an air intake pipe, an air outlet channel and an air outlet pipe. The air outlet pipe is spirally arranged in the guide groove. A plurality of air outlet holes are evenly spaced on the air outlet pipe. A cavity is formed inside the mixing element. The air outlet end of the air outlet pipe is connected to the interior of the mixing element. One end of the air outlet channel is connected to the interior of the mixing element.

[0015] Preferably, a reaction mechanism is also provided in the tank body, and the reaction mechanism is located at the lower side of the mixing mechanism. The reaction mechanism includes an outer cylinder and a rotating part. The outer cylinder is unidirectionally rotatably matched with the tank body.

[0020] Preferably, the width of the outer cylinder decreases from top to bottom, and the width of the rotating member decreases from top to bottom.

[0021] A fuel reaction method comprises the following steps:

[0025] The beneficial effects are: promoting full mixing and reaction of oil and hydrogen. After the oil is introduced into the tank body, it flows in the guide groove. The feed component introduces hydrogen into the guide groove and fully mixes it with the oil in the guide groove, thereby increasing the contact range of hydrogen and oil. The floating hydrogen can enter the outlet pipe again from the outlet channel through the circulation channel, thereby achieving repeated mixing and reaction of the floating hydrogen and oil, and improving the mixing and reaction efficiency of hydrogen and oil.

[0026] The beneficial effects of the present invention are:

[0027] (1) Promote the full mixing and reaction of oil and hydrogen. After the oil is introduced into the tank body, it flows in the guide groove. The feed component introduces hydrogen into the guide groove and fully mixes it with the oil in the guide groove. Compared with the traditional method of directly introducing hydrogen into the tank body, the contact range of hydrogen and oil is improved, and the floating hydrogen can enter the outlet pipe again through the outlet channel through the circulation channel, thereby realizing repeated mixing and reaction of the floating hydrogen and oil, improving the mixing and reaction efficiency of hydrogen and oil, and ensuring the hydrogenation treatment effect of the oil.

[0028] (2) Reduce the speed of hydrogen rising in the oil and promote the mixing and reaction of hydrogen and oil. When the driving element drives the mixing element to rotate, the space of the guide groove formed by spiral plate 2 and spiral plate 1 changes with the rotation of the mixing element. When the space of the guide groove decreases, the pressure in the guide groove increases, slowing down the speed of hydrogen rising, promoting the full contact between hydrogen and oil, and further improving the reaction efficiency of oil and hydrogen.

[0029] (3) The hydrogen is promoted to fully contact with the oil in the guide groove. After the hydrogen enters the connecting groove from the outlet channel, it further enters the connecting piece from the air inlet of the connecting piece, and further enters the outlet pipe, and is finally discharged from the outlets on the outlet pipe. In addition, when the mixing element rotates, the distance between the spiral plate 1 and the spiral plate 2 is changed. The connecting piece rotates in coordination with the rotation of the spiral groove on it and the slider at the connecting groove, and drives the blades to rotate, stirring the oil around the connecting piece, causing disturbance to the oil, thereby allowing the oil to further fully contact and react with the hydrogen.

DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figure 1 As shown, the fuel reaction device of the present invention comprises a tank body 1, on which a liquid inlet 11 and a liquid outlet 12 are provided. Untreated fuel enters the tank body 1 from the liquid inlet 11, and the fuel treated with hydrogen is discharged from the liquid outlet 12 and collected. A mixing mechanism for mixing fuel and hydrogen is provided in the tank body 1.

[0039] The mixing mechanism includes a guide member 21, a mixing member 22 and an air intake assembly. A mixing chamber is formed inside the guide member 21. The mixing member 22 is arranged in the mixing chamber. The guide member 21, the mixing member 22 and the tank body 1 are coaxially arranged. A spiral plate 1 211 is provided on the inner wall of the guide member 21. A spiral plate 221 is provided on the outer side of the mixing member 22. The spiral plates 1 211 and 221 overlap and have the same spiral direction. The spiral plates 1 211 and 221 form a spiral guide groove between the guide member 21 and the mixing member 22. The liquid inlet 11 is connected to the upper end of the guide groove. The oil flows from top to bottom along the guide groove. The bottom diameter of the guide member 21 is reduced to form a cone. An opening is provided at the bottom of the guide member 21. After the oil is mixed in the mixing chamber, it flows out from the opening at the bottom of the guide member 21.

[0040] The mixing element 22 is also connected to a driving element 2, which may be a motor. The driving element 2 is fixed to the mixing element 22 via a driving shaft. The driving element 2 drives the mixing element 22 to rotate. When the mixing element 22 rotates, the spacing between the spiral plate 1 211 and the spiral plate 221 changes, and the space size of the guide groove changes. When the space in the guide groove decreases, the gas inside it is compressed and the pressure increases, which facilitates the mixing of hydrogen and oil.

[0041] like Figures 3 to 5 As shown, the air intake assembly is used to introduce hydrogen into the guide groove. The air intake assembly includes an air intake pipe 3, an air outlet channel 31 and an air outlet pipe 32. The air outlet pipe 32 is spirally arranged in the guide groove. A plurality of air outlet holes are evenly spaced on the air outlet pipe 32. A cavity is formed inside the mixing element 22. The air outlet end of the air outlet pipe 32 is connected to the inside of the mixing element 22. One end of the air outlet channel 31 is connected to the inside of the mixing element 22. The other end of the air outlet channel 31 is connected to the air outlet pipe 32 through a connecting structure, and the gas in the mixing element 22 is introduced into the air outlet pipe 32. 2. The outlet pipe 32 is slidably matched with the spiral plate 1 211 and does not separate from the spiral plate 1 211. The outlet pipe 32 rotates with the spiral plate 221. The hydrogen enters the interior of the mixing element 22 from the intake pipe 3, and is further introduced into the outlet pipe 32 through the outlet channel 31, and is finally discharged from the outlet holes in the outlet pipe 32, so that the hydrogen is fully mixed with the oil in the guide groove. The rotation operation of the mixing element 22 further promotes the pressure change in the guide groove, so that the mixing effect of the hydrogen and the oil is improved when the space in the guide groove is squeezed.

[0042] The connecting structure includes a connecting groove 311, a connecting piece 33 and an elastic piece. The connecting groove 311 is arranged on the spiral plate 221. The outlet end of the gas outlet channel 31 is connected to the connecting groove 311. The connecting piece 33 is hollow inside. An air inlet is arranged on the upper end of the connecting piece 33. The upper end of the connecting piece 33 extends into the connecting groove 311. The elastic piece is arranged in the connecting groove 311 and abuts against the upper end of the connecting piece 33. The side wall of the connecting piece 33 is slidably and closedly connected to the connecting groove 311. The lower end of the connecting piece 33 is connected to the gas outlet pipe 32. The gas in the mixing element 22 enters the connecting groove 311 through the gas outlet channel 31, and further enters the air inlet at the upper end of the connecting piece 33 in the connecting groove 311, and finally enters the gas outlet pipe 32 through the connecting piece 33. In order to improve the efficiency of hydrogen introduction, a plurality of gas outlet channels 31 and a plurality of connecting structures can be provided, and each gas outlet channel 31 corresponds to each connecting structure one by one.

[0043] In order to further promote the mixing of oil and hydrogen, a spiral groove is provided on the outer wall of the connecting member 33, and a slider that slides with the spiral groove is provided on the connecting groove 311. The lower end of the connecting member 33 is sealed and rotatably connected to the air outlet. A blade 34 is fixed on the connecting member 33. When the relative spacing between the spiral plate 1 211 and the spiral plate 2 221 changes, the connecting member 33 rotates with the cooperation of the slider and the spiral groove, and drives the blade 34 to rotate, thereby stirring the oil around the connecting member 33, promoting oil disturbance, making the oil fully contact with the hydrogen, and improving the mixing effect of the oil and hydrogen.

[0044] A sealing block is provided at the upper and lower ends of the guide groove, and a groove body is provided on the spiral plate 221. The upper end of the sealing block is elastically connected to the groove body, and the lower end of the sealing block abuts against the spiral plate 221. A notch is provided in the middle of the sealing block. When the spiral plate 221 approaches the spiral plate 1 211, the sealing block is squeezed into the groove body and the notch is staggered with the guide groove. When the spiral plate 221 and the spiral plate 1 211 are relatively far apart, the notch on the sealing block is in the guide groove, and the oil can flow through the notch. When the spacing between the spiral plate 221 and the spiral plate 1 211 is reduced, the sealing block is squeezed until the notch is staggered with the guide groove, and the guide groove is in a relatively closed state in the area between the two sealing blocks, so that when the spiral plate 221 approaches the spiral plate 1 211, the pressure in the guide groove is adjusted according to the spatial change, thereby promoting the full mixing and reaction of the oil and hydrogen in this area.

[0045] A circulation channel 35 is also provided on the mixing element 22, one end of the circulation channel 35 is connected to the guide groove, and the other end of the circulation channel 35 is unidirectionally connected to the gas outlet channel 31. The circulation channel 35 can be connected to the gas outlet channel 31 through a one-way valve. When the oil and hydrogen are mixed, the hydrogen flowing above the oil level enters the gas outlet channel 31 through the circulation channel 35, and further re-enters the gas outlet pipe 32 through the connecting structure, so that the upper layer of hydrogen automatically circulates in the mixing operation of the oil and hydrogen, so that the hydrogen is fully in contact with the oil, thereby improving the utilization efficiency of the hydrogen.

[0046] like Figure 1 and Figure 2 As shown, a reaction mechanism is also provided in the tank body 1, and the reaction mechanism is located at the lower side of the mixing mechanism. The reaction mechanism includes an outer cylinder 41 and a rotating member 4. The rotating member 4 is provided on the inner side of the outer cylinder 41. A gap for accommodating a catalyst is formed between the rotating member 4 and the outer cylinder 41. In order to facilitate the mixed oil to smoothly enter the gap between the outer cylinder 41 and the rotating member 4, the upper end surface of the rotating member 4 is lowered in height along the direction away from the axial direction of the tank body 1. A bottom plate is provided at the bottom of the outer cylinder 41, and a plurality of filter holes are provided on the bottom plate. The rotating member 4 is fixed relative to the mixing member 22.

[0047] When the mixed oil reacts with the catalyst, impurities will be separated. The impurities adhered to the catalyst and will affect the reaction of the catalyst with the subsequent oil. In order to reduce the influence of the impurity adhesion on the catalytic reaction, the outer cylinder 41 is matched with the tank body 1 for unidirectional rotation, and the rotating part 4 is matched with the bottom of the outer cylinder 41 for frictional rotation. When the rotating part 4 rotates in one direction, the outer cylinder 41 is driven to rotate synchronously by the action of friction. When the rotating part 4 rotates in the other direction, the rotation of the outer cylinder 41 is restricted. In the process of the reaction between the oil and the catalyst, the rotation direction of the rotating part 4 is adjusted at intervals so that the rotating part 4 rubs the catalyst to ensure the catalytic effect of the catalyst.

[0048] Specifically, the one-way rotation of the outer tube 41 can be limited by the cooperation between the tooth portion 411 and the spring block 412. The outer circumference of the outer tube 41 is evenly provided with tooth portions 411. The inner wall of the tank body 1 is elastically connected with a plurality of spring blocks 412. Each spring block 412 is respectively located between two adjacent tooth portions 411. The end faces of the spring block 412 opposite to the two adjacent tooth portions 411 are respectively a straight face and an inclined face. When the tooth portion 411 squeezes the inclined face of the spring block 412, the spring block 412 is pushed back to the inner wall of the tank body 1 and avoids the tooth portion 411.

[0049] A fuel reaction method comprises the following steps:

[0050] S1. Raw material preparation: crude oil is initially refined to remove most impurities and water in the oil to obtain semi-finished fuel oil suitable for hydrotreating;

[0051] S2, mixing, mixing the semi-finished fuel oil and hydrogen in a certain proportion and passing through the fuel oil reaction device provided by the present invention to mix and react;

[0052] S3, separation and purification, after the reaction is completed, the product is separated from the unreacted raw materials, and the unreacted raw materials are returned to the mixing step for mixing treatment, and the product is further purified and then cooled to room temperature for storage.
