とを特徴とする排熱回収装置。1. A heat storage tank with a water supply pipe in the lower part and a hot water supply pipe in the upper part, and a hydrogen flow pipe containing two types of metal hydrides with different hydrogen equilibrium pressure characteristics and having a valve in the middle. Consisting of at least one pair of connected reactors, each reactor is provided with a heat exchange section, and the outlet and inlet of the heat exchange section provided in the reactor sealed with a metal hydride having a low hydrogen equilibrium pressure are as described above. The upper part of the heat storage tank is connected to the upper part of the heat storage tank, and the lower part of the heat storage tank is connected to the lower part of the heat storage tank by a pipe, and both pipes are switchable. The outlet and inlet of the heat exchange section provided in the reactor sealed with the heat exchanger are respectively connected to the lower part of the heat storage tank by pipes, and are also connected to the waste heat source by the pipes, and both pipes are switched. An exhaust heat recovery device characterized by being made possible.
