Description
Technical Field
The invention relates to a coupling sleeve hydrogen storage reactor of a composite fin and metal foam in the fields of heterogeneous reaction and hydrogenation/dehydrogenation reaction, and belongs to the field of chemical reactors. The method is suitable for chemical reactions of hydrogenation/dehydrogenation of metal hydrides with large reaction heat effect.
Background
At present, hydrogen storage reactors with large thermal effect in the hydrogenation/dehydrogenation reaction process at home and abroad mainly comprise the following types:
water jacket type hydrogen storage reactor-reactor shell is cylindrical, and the interior of the shell is a metal hydride bed layer. Hydrogen enters from the top of the reactor and diffuses towards the metal hydride bed. The shell is externally provided with a water jacket, and heat exchange in the hydrogenation/dehydrogenation process is carried out through the water jacket on the outer side of the shell. The reactor has the advantages of simple structure, easy processing and the like, but because the heat exchange of the central area of the reactor is poor, the reaction efficiency is not high, and the temperature distribution of the bed layer is not uniform. (International Journal of Hydrogen energy.2011, 36; 4952-
The single-tube fin type hydrogen storage reactor is characterized in that a reactor shell is cylindrical, a central heat exchange straight tube is arranged in the center of the reactor, fins are connected to the heat exchange straight tube, and a cavity between the central heat exchange straight tube and the shell is filled with metal hydride. Hydrogen enters from the top of the reactor and diffuses to the metal hydride bed layer, and the heat exchange in the hydrogenation/dehydrogenation process is carried out through the fins and the central heat exchange straight pipe. The reactor has simple structure and easy processing, but because the heat exchange is mainly carried out through the central heat exchange straight pipe, the heat exchange area is smaller, the reactor is not suitable for occasions with larger heat effect of hydrogen storage reaction, the heat exchange is poorer near the shell area, and the temperature distribution of a bed layer is not uniform. (International Journal of Hydrogen energy.2011, 36; 4952-4957.)
Spiral tube type hydrogen storage reactor-reactor shell is cylindrical, the center of the reactor is provided with a spiral tube, and a cavity between the shell and the spiral tube is filled with metal hydride. Hydrogen enters from the top of the reactor and diffuses towards the metal hydride bed. Compared with a single-tube fin type hydrogen storage reactor, the reactor uses the spiral tube for heat exchange, increases the convection heat exchange area and heat exchange fluid disturbance, has higher heat exchange efficiency, but has large manufacturing difficulty of the spiral tube, higher cost and uneven bed layer heat exchange. (Applied energy 2014, 130; 712-722.)
A microchannel hydrogen storage reactor is characterized in that a plurality of microchannel heat exchange tubes are used for replacing a central heat exchange tube in order to further improve the heat exchange efficiency of the hydrogen storage reactor. The reactor has high heat exchange efficiency, uniform bed layer reaction and temperature distribution, but complex microchannel processing technology and high manufacturing cost, and the microchannel is easily damaged by the volume expansion of the metal hydride alloy in the hydrogenation/dehydrogenation process and the thermal stress generated by nonuniform temperature distribution in the bed layer. (International Journal of Hydrogen energy.2013, 38; 15242-
Other hydrogen storage reactors, such as U-shaped tube fins, arch-shaped plates, multi-tube bundle fins, staggered rib plate hydrogen storage reactors, etc., have the advantages of good heat exchange effect, compact structure, etc., but are difficult to be applied in large scale due to complex processing. Therefore, the existing main hydrogen storage reactors have some defects and are difficult to be applied on a large scale.

The thickness of the filter screen is 0.5-1mm, the material is stainless steel, and the aperture is 300-500 meshes. And a gas safety valve 12 is arranged on the upper end enclosure 6 to prevent the reactor from being damaged by overhigh hydrogen pressure.

from the above reaction equation, LaNi 5 The reaction heat in the alloy hydrogenation/dehydrogenation reaction process reaches 30.3 kJ.mol -1 The thermal effect is large, and if the heat exchange performance between the reactor bed layer and the heat exchange fluid is poor, the overall performance of the hydrogen storage reactor is affected.

Therefore, good heat exchange performance of the hydrogen storage reactor is a substantial guarantee of the hydrogenation/dehydrogenation reaction. The invention has good heat exchange characteristic and can ensure normal hydrogenation/dehydrogenation reaction.
