Description

Technical Field

[0001] The invention belongs to the technical field of liquid organic hydride dehydrogenation, and in particular relates to liquid organic hydride dehydrogenation equipment. Background Art

[0002] Hydrogen energy is an important resource and plays an irreplaceable role in the fields of energy, chemical industry, medicine, etc. Dehydrogenation of organic hydrides is an important means of producing hydrogen, such as cyclohexane dehydrogenation, cyclohexanol dehydrogenation, isopropanol dehydrogenation, etc. In addition to obtaining hydrogen, chemical products such as benzene, cyclohexanone, and acetone can also be obtained, occupying an important position in the industry.

[0003] The existing organic hydride dehydrogenation equipment has the following problems:

[0004] Existing organic hydride dehydrogenation equipment uses waste heat to dehydrogenate organic hydrides, but cannot catalytically dehydrogenate organic hydrides based on the temperature of the waste heat. After the relatively low-temperature waste gas heats the catalyst, the organic hydride liquid is sprayed onto the catalyst surface. Due to the low temperature of the waste gas, the sprayed catalyst temperature recovers slowly to the required catalytic temperature, resulting in low dehydrogenation efficiency of the organic hydride liquid.

[0005] When utilizing waste gas with relatively high temperature, the organic hydride liquid contacts the catalyst surface unevenly, resulting in a slow dehydrogenation rate of the organic hydride by the waste gas with high temperature, and the waste gas with high temperature cannot be fully utilized. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a liquid organic hydride dehydrogenation device. In order to address the problem that the high or low waste heat temperature affects the dehydrogenation efficiency of the organic hydride, the present invention applies the principle of turning harm into benefit and makes dual use of the waste gas. On the one hand, the impact force of the waste gas is used to convert wind power into electricity, and the waste gas with lower temperature is insulated. On the other hand, with the intervention of the buffer blades, the heat absorption block can absorb the heat in the waste gas with maximum efficiency, thereby ensuring the catalytic temperature of the catalyst and increasing the dehydrogenation amount of the organic hydride. This solves the technical problem that the high or low waste heat temperature affects the dehydrogenation efficiency of the organic hydride, which is difficult to solve in the prior art.

[0007] The present invention provides a liquid organic hydride dehydrogenation device which can adaptively utilize the heat in exhaust gas with different temperatures and ensure that the catalyst dehydrogenates the organic hydride at a temperature most suitable for dehydrogenation.

[0008] The technical solution adopted in this scheme is as follows: This scheme proposes a liquid organic hydride dehydrogenation equipment, including a dehydrogenation cylinder, a stabilizing frame, a hydrogen compound storage box, a segmented waste heat utilization mechanism and a heat-sufficient self-rotating hydrogen extraction mechanism. The stabilizing frame is symmetrically arranged on the bottom walls at both ends of the dehydrogenation cylinder, and multiple groups of hydrogen compound storage boxes are arranged through the side walls of the dehydrogenation cylinder.

[0010] During use, the exhaust pipe is connected to the air intake one-way valve, and the heated exhaust gas enters the interior of the air intake ladder bucket through the exhaust pipe. The exhaust gas inside the air intake ladder bucket enters the interior of the extraction channel. When the exhaust gas circulates inside the extraction channel, it blows the blades of the small wind turbine, and the small wind turbine generates electricity under the rotation of the blades. The small wind turbine supplies power to the induction coil, and the induction coil heats the wrapped iron sheet layer after being energized. Since the wrapped iron sheet layer is on the inner wall of the heating tank, the wrapped iron sheet layer transfers heat to the exhaust gas inside the extraction channel through the insulation port, which can keep the exhaust gas flowing through the extraction channel warm.

The annular heat-absorbing copper block absorbs heat from the exhaust gas through the heat-absorbing port. The temperature of the annular heat-absorbing copper block rises to heat the catalyst layer. After the temperature of the catalyst layer rises, it is convenient to extract hydrogen from the organic hydride. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Specifically, a controller 45 is provided on the side wall of the air intake ladder 6 .

[0040] The controller 45 is electrically connected to the rotating motor 24 and the atomizing motor 37 respectively.

[0041] Preferably, the induction coil 16 is electrically connected to the small wind generator 19 .

[0042] During specific use, in Example 1, the hydrogen one-way valve 41 is connected to the hydrogen storage device through a pipeline, the exhaust gas pipeline is connected to the intake one-way valve 8, and the exhaust gas with temperature enters the intake ladder hopper 6 through the exhaust gas pipeline, and the exhaust gas inside the intake ladder hopper 6 enters the extraction channel 11.

[0043] Specifically, when the exhaust gas circulates inside the extraction channel 11, it blows the blades of the small wind turbine 19, and the small wind turbine 19 generates electricity under the rotation of the blades. The small wind turbine 19 supplies power for the insulation operation of the induction coil 16. After the induction coil 16 is energized, it heats the wrapped iron sheet layer 15 under the magnetic induction effect. Since the wrapped iron sheet layer 15 is located on the inner wall of the heating tank 14, the wrapped iron sheet layer 15 transfers heat to the exhaust gas inside the extraction channel 11 through the insulation port 44, which can keep the exhaust gas flowing through the extraction channel 11 warm. The annular heat-absorbing copper block 17 absorbs heat from the exhaust gas through the heat-absorbing port 43. The temperature of the annular heat-absorbing copper block 17 increases, which heats the catalyst layer 18. After the temperature of the catalyst layer 18 increases, it is convenient to perform hydrogen extraction operation on the organic hydride.

[0044] During the extraction process, the organic hydride liquid to be extracted is added to the hydrogen compound storage tank 3. The controller 45 controls the atomizing motor 37 to start. The atomizing motor 37 extracts the organic hydride liquid from the hydrogen compound storage tank 3 through the atomizing delivery pipe 38. The organic hydride liquid is atomized by the atomizing motor 37 and then enters the sliding box 29 through the spray telescopic pipe 39. The sliding box 29 sprays the organic hydride toward the heated catalyst layer 18 through the spray head 40.

[0045] At this time, the controller 45 controls the rotation motor 24 to start, and the rotation motor 24 drives the driving gear 26 to rotate through the driving shaft 25. The driving gear 26 is meshed with the driving gear plate 22. The driving gear 26 drives the extraction channel 11 to rotate through the driving gear plate 22. The extraction channel 11 drives the catalyst layer 18 to rotate through the annular heat-absorbing copper block 17, so that the organic hydride liquid sprayed by the spray head 40 can be evenly sprayed on different areas of the surface of the catalyst layer 18, which helps to improve the extraction efficiency of the hydrogen in the organic hydride liquid by the catalyst layer 18. The controller 45 controls the driving electromagnet 30 and the spraying electromagnet 31 to start, and the driving electromagnet 30 and the spraying electromagnet 31 are energized to generate magnetism, and the guide rod The driving electromagnet 30 and the spraying electromagnet 31 at one end of the guide rod 28 are arranged with the same pole, and the driving electromagnet 30 and the spraying electromagnet 31 at the other end of the guide rod 28 are arranged with different poles. The driving electromagnet 30 is fixed to the side wall of the rotating frame 10 and the spraying electromagnet 31 is driven by magnetic force to move. The spraying electromagnet 31 drives the sliding box 29 to reciprocate along the guide rod 28. The guide rod 28 drives the spray head 40 to spray the multiple groups of catalyst layers 18, so as to leave a certain temperature rising space for the catalyst layer 18 after being sprayed, so that the catalyst layer 18 can efficiently complete the extraction of hydrogen from the organic hydride at the catalytic temperature. After utilizing the waste heat of the exhaust gas, the exhaust gas flows into the interior of the exhaust cone 7 and is discharged through the exhaust one-way valve 9.

[0046] Example 2, based on the above example, when the temperature of the exhaust gas entering the extraction channel 11 is high, multiple groups of fixed sliding boxes 29 can be set outside the guide rod 28, and the controller 45 controls the atomizing motor 37 to start. The atomizing motor 37 transports the organic hydride inside the hydrogen compound storage box 3 through the atomizing delivery pipe 38. The organic hydride is transported to the inside of the sliding box 29 through the spray telescopic pipe 39. The sliding box 29 sprays the catalyst layer 18 with a higher temperature outside the extraction channel 11 through the spray head 40. At this time, the controller 45 controls the rotating motor 24 to start The rotating motor 24 drives the driving gear 26 to rotate through the driving shaft 25, and the driving gear 26 drives the extraction channel 11 to rotate through the driving gear plate 22. The extraction channel 11 drives the catalyst layer 18 to rotate through the annular heat-absorbing copper block 17. Under the setting of the guide rod 28, the catalyst layer 18 has space to recover the temperature during rotation, so that the extraction rate of organic hydride will not be low during the hydrogen extraction operation, thereby improving the extraction efficiency of organic hydride by waste heat, and hydrogen is discharged into the interior of the hydrogen energy storage device through the hydrogen one-way valve 41; repeat the above operation when using it next time.
