Device and method for on-line conversion of sodium source into heat energy and hydrogen

The invention discloses a device and a method for on-line conversion of a sodium source into heat energy and hydrogen. A non-polar organic solvent temperature sensor, an alkali liquor temperature sensor, a pressure sensor and a liquid level meter capable of detecting liquid levels of alkali liquor and a non-polar organic solvent are arranged in a reactor; the controller collects and detects signals and can control the temperature of the alkali liquor, the temperature of the non-polar organic solvent, the pressure, the water layer and the non-polar organic solvent layer to be within a set range by controlling the drain valve, the feeding valve, the liquid inlet valve, the liquid outlet valve, the heat exchange valve and the like. The reaction speed of sodium and water is stable and controllable, the generated hydrogen is high in pressure and stable in flow velocity, the problem of safe and rapid reaction of sodium and water is effectively solved, and the hydrogen does not need to be separated and does not need
