The method of metal hydride Hydrogen Energy power generation of the present invention, including 3 processes, process are as follows:
(1) process 1, hydrogen inlet, upper hydrogen outlet and lower hydrogen inlet, lower hydrogen outlet in closing, opens hydrogen inlet valve , the hydrogen under atmospheric pressure enters the intermediate hydrogen chamber of cylinder from the hydrogen inlet in the lower left side of cylinder, and in atmospheric pressure Under the action of push upper piston move up, the intracavitary hydrogen of upper hydrogen be negative pressure, as upper piston persistently moves up, upper hydrogen chamber Interior Hydrogen Vapor Pressure is gradually increased, and increases to atmospheric pressure, opens upper hydrogen inlet, upper hydrogen outlet, upper metal hydrogen at this time Compound starts to inhale hydrogen and releases heat, until upper metal hydride is complete by absorption of hydrogen.Inhale the heat released during hydrogen It is removed by A hydrogen gas circulating pump.
(2) the valve on the hydrogen inlet of cylinder is closed in process 2, opens the valve on hydrogen outlet, and opens lower hydrogen Entrance valve heats lower metal hydride hydrogen release at a certain temperature, generates the hydrogen of certain pressure, push lower piston to Upper movement, the hydrogen outlet discharge of the upper right side by the hydrogen in intermediate hydrogen chamber from cylinder, until hydrogen is all discharged.
