Abstract

The invention discloses a self-heating dehydrogenation reaction device, relates to the field of dehydrogenation reaction devices, solves the technical problems of high energy loss, large device volume and low dehydrogenation efficiency of dehydrogenation reaction, and adopts the technical scheme that a self-heating reaction cavity, a temperature control cavity and a dehydrogenation reaction cavity are integrally designed in a dehydrogenation reaction unit; and an upper end plate, a lower end plate and a fastener are used for fixing dehydrogenation reaction units which are stacked in series, and the dehydrogenation reaction units are assembled to obtain a dehydrogenation reaction device. A self-heating reaction cavity generates heat through the chemical reaction between hydrogen and air, then the heat is transferred to a temperature control cavity through an isolation thin wall, the temperature control cavity conducts the heat to the dehydrogenation reaction cavity through heat conduction agent flowing convection heat exchange, and the needed heat is continuously provided for the dehydrogenation reaction. The whole process is small in energy loss, heat loss in the heat conduction process is reduced, and the device is small in size, high in power density and high in dehydrogenation energy efficiency.

Description

technical field [0001] The disclosure relates to the field of dehydrogenation reaction devices, in particular to an autothermal dehydrogenation reaction device. Background technique [0002] The essence of dehydrogenation is to produce hydrogen and obtain hydrogen energy. It can also be used for the treatment of hydrogen-containing tail gas and tail liquid. The reaction process is to make the liquid or gas containing hydrogen atoms pass through a reactor at a certain temperature, and the hydrogen in the material is catalyzed. detachment, forming hydrogen gas overflow. [0003] The dehydrogenation reaction is an endothermic reaction. If a stable hydrogen flow is to be obtained, it is necessary to ensure that the reactor can continuously provide the heat required for dehydrogenation. The heat supply system, temperature control system and reaction system of the existing dehydrogenation reaction device are generally set separately, and the heat conduction energy loss is relativ...
