The invention discloses a multi-layer net shaped staggered rib plate type hydrogen storage reaction device. The device is of a three-dimensional structure and comprises a housing, wherein the upper end and the lower end of the housing are correspondingly connected to an upper sealing head and a lower sealing head through flange structures in a sealing manner; a heat exchanging pipe is arranged inthe center of the housing; a plurality of layers of circumferential rib plates are sequentially arranged at the outer part of the heat exchanging pipe; a radial rib plate is arranged between two adjacent layers of circumferential rib plates; a reaction bed layer is arranged in each of the spaces formed by the radial rib plates and the circumferential rib plates; a tubular plate is arranged betweenthe upper sealing head and the housing, and an air phase buffering chamber is formed between the tubular plate and the upper sealing head; a heat exchanging liquid inlet which communicates with the heat exchanging pipe, an air phase inlet which is connected to the air phase buffering chamber and an air safety valve are arranged on the upper sealing head. The device is applicable to high reactionheat effect chemical reaction such as dehydrogenation or hydrogenation of metal hydride. The device has the advantages of being high in heat transfer rate, simple to operate, compact in structure, andconvenient to maintain.
