Description

Technical Field

[0001] The utility model relates to the technical field of dehydrogenation, in particular to a dehydrogenation reactor. Background Art

[0002] The dehydrogenation reaction of an organic compound in the presence of a catalyst (chromium oxide, iron oxide, etc.) or a dehydrogenating agent (sulfur or selenium, etc.) at high temperature is a form of oxidation reaction. Hydrogen mainly appears in the form of a compound on Earth and is the most widely distributed substance in the universe. It constitutes 75% of the mass of the universe and is a secondary energy source.

[0003] For example, a liquid organic hydrogen storage material dehydrogenation reactor with the application publication number "CN114653311A" is a reactor in which liquid hydrogen storage material storing hydrogen is introduced into a reaction shell, so that it undergoes a catalytic reaction with a catalytic layer to produce a mixture of hydrogen and hydrogen storage carrier liquid foam, which then enters a second cavity; when the hydrogen storage carrier liquid foam mixed with hydrogen drips and contacts a diverter hood, it will be adsorbed on the surface of the diverter hood and converge from a liquid foam state to a liquid state, flow down along the surface of the diverter hood and accumulate at the bottom of the reaction shell, and then be discharged from the discharge port; and hydrogen will separate from the liquid foam on the surface of the diverter hood as the hydrogen storage carrier liquid foam converges, and the demister will intercept the hydrogen storage carrier liquid foam in the gas that has not contacted the diverter hood, allowing only the separated hydrogen to enter the space inside the diverter hood and be discharged from the gas outlet pipe. However, in the dehydrogenation reactor of the liquid organic hydrogen storage material, the liquid hydrogen storage material storing hydrogen undergoes a catalytic reaction with the catalytic layer to produce a mixture of hydrogen and hydrogen storage carrier liquid foam. The catalytic layer containing the catalyst is fixed inside the reaction shell, and the liquid hydrogen storage material storing hydrogen continuously passes through the catalytic layer containing the catalyst, resulting in incomplete contact between the liquid hydrogen storage material storing hydrogen and the catalyst. As a result, the liquid hydrogen storage material storing hydrogen requires a longer reaction time to reach the dehydrogenation standard, thereby reducing work efficiency. Utility Model Content

[0027] Working principle:

[0028] When dehydrogenation is carried out using a dehydrogenation reactor:

[0029] Preparation process:

[0030] The operator first inserts the baffle 4 and the filter screen 3 into the dehydrogenation reactor 2 along the slide grooves processed on the dehydrogenation reactor 2, opens the valve on the discharge port 5, and adds the liquid hydrogen storage material containing hydrogen into the dehydrogenation reactor 2 from the feed port 5. Then, the valve of the catalyst feeding port 6 is opened and an appropriate amount of catalyst is added into the dehydrogenation reactor 2 from the catalyst feeding port 6.

[0031] Dehydrogenation reactor dehydrogenation process:

[0032] The power supply of the hydraulic cylinder 702 is started, and the telescopic end of the hydraulic cylinder 702 moves back and forth, driving the slide rod 703 to slide back and forth along the slide groove processed on the inner wall of the second shell 701. At the same time, the protruding part of the slide rod 703 slides back and forth along the slide groove processed on the roller 704, thereby driving the roller 704 to rotate. The rotation of the roller 704 drives the first bevel gear 705 to rotate clockwise, thereby driving the second bevel gear 706 and the first rotating shaft 708 to rotate clockwise. The rotation of the second bevel gear 706 drives the third bevel gear 707 to rotate counterclockwise. The rotation of the third bevel gear 707 drives the second rotating shaft 709 to rotate counterclockwise. The first rotating shaft 708 and the second rotating shaft 709 rotate in opposite directions, driving the first fan blade 11 and the second fan blade 12 to rotate in opposite directions, so as to increase the contact area between the catalyst and the liquid hydrogen storage material storing hydrogen, thereby achieving a rapid reaction between the catalyst and the liquid hydrogen storage material storing hydrogen, thereby improving work efficiency.

[0033] The power supply of the heating block 10 is started, and the heating block 10 generates heat to heat the dehydrogenation reactor 2, thereby increasing the temperature of the liquid hydrogen storage material and the catalyst storing hydrogen. The power supply of the motor 902 is started, and the output shaft of the motor 902 rotates to drive the turntable 903 to rotate eccentrically, thereby driving the movable frame 904 to move. The movable frame 904 slides along the slide groove processed on the vertical rod 905, thereby driving the vertical rod 905 to slide back and forth along the through hole processed on the first shell 901. The vertical rod 905 slides back and forth, driving the heating block 10 to slide back and forth, so as to achieve a rapid reaction between the liquid hydrogen storage material storing hydrogen and the catalyst through heating. After the reaction is completed, the power supply of the motor 902 and the hydraulic cylinder 702 is turned off. During the reaction, the pressure in the dehydrogenation reactor 2 can be controlled by the valve of the exhaust port 8 to prevent the dehydrogenation reactor 2 from exploding.

[0034] Discharging process:

[0035] The hydrogen is discharged from the exhaust port 8, and the baffle 4 is pulled out, so that the filter 3 can filter out impurities carried by the liquid hydrogen storage material during the reaction or when storing hydrogen, so as to complete the gas-liquid separation. The filtered liquid can be discharged from the discharge port 13 by opening the valve of the discharge port 13. After the liquid is discharged, the filter 3 is pulled out so that the impurities are discharged from the discharge port 13 due to gravity, and the operator collects and processes them.
