HYDROGEN OCCLUSION ALLOY REACTOR

摘要

PURPOSE:To raise heat exchange rate and reaction rate, by equipping a means to introduce a hydrogen gas into hollow parts of molded articles and to discharge the gas and a means to feed a heating (refrigeration) medium to voids between heat transfer pipes and conduits and to release the heating (refrigeration) medium. CONSTITUTION:Molded articles 1 of hydrogen occlusion alloy which have hollow parts 2 and heat transfer pipes 3 are stuck fast to the outer periphery of the molded articles 1 and cover the molded articles. Conduits 5 surround the outer periphery of the heat transfer pipes 3 in parallel while making small gaps 4 between the pipes and the conduits and these conduits are piled to form a thermal reactor 6 and the reactor is horizontally supported in parallel in a closed container 7. The container 7 is provided with an inlet 8 to feed a heating (refrigeration) medium and an outlet 9 and the heating (refrigeration) medium is rapidly circulated through narrow sections of the voids 4. The container 7 is also equipped with a hydrogen gas inlet 10 to introduce and release a hydrogen gas and the gas is circulated through the hollow parts 2 in the molded articles. Consequently, flow velocity of the medium is increased, the voids 4 can be narrowly designed and made with ease and total amount of the medium retaining in the reactor can be lessened.
