Fluid-guiding type hydrogen production plant and hydrogen production method thereof

The invention relates to a tube-flow hydrogen producing device and a hydrogen producing method thereof. The invention belongs to the technical field of hydrogen preparation. The tube-flow hydrogen producing device comprises an aluminum paste pot, an alkali liquor pot and a hydrogen generator, and is characterized in that the aluminum paste pot and the alkali liquor pot are connected with the hydrogen generator through a metering pump. respectively; the hydrogen generator has a double-layer tubular structure, is divided into a reaction zone and a heat exchange zone, and is connected with a s-water separator through a pipe. The hydrogen producing method of the tube-flow hydrogen producing device is characterized in that fluidized aluminum in the aluminum paste pot and the alkali liquor in the alkali liquor pot enter the reaction zone in the hydrogen generator with double-layer tubular structure to react according to reaction proportion through the metering pump, so as to produce the hydrogen; the heat exchange zone of the hydrogen generator is passed through by cooling liquid for heat exchange; and the hydrogen and reaction waste liquor enter the gas-water separator. The tube-flow hydrogen producing device has the advantages of high hydrogen production rate, high purity of the hydrogen, no power consumption, small pollution, high pressure of output hydrogen, stable flow rate, simple structure, safety and reliability, good controllability, and wide application range and so on.
