Aluminum hydrolization hydrogen production device and controlling method thereof

Abstract

The invention relates to an aluminum hydrolization hydrogen production device and a controlling method thereof, which belongs to the technical field of hydrogen preparation. The aluminum hydrolizationhydrogen production device comprises an aluminum hydrolization tank body; an aluminum end socket, an amalgam, a baffle, a water inlet and a hydrogen outlet are arranged on the tank body; the tank body is connected with the aluminum end socket in a sealing way; the amalgam is covered on the aluminum end socket and a water reaction interface; the baffle in the tank body is positioned at the upper part of the aluminum and the water reaction interface; and the hydrogen outlet is positioned at the top part of the tank body. The controlling method of the aluminum hydrolization hydrogen production device is characterized in that during the reaction of aluminum hydrolization in the tank body, the temperature of the reaction interface is regulated and controlled to realize the rate controlling foraluminum production; or the amalgam is regulated and controlled to contact with or be separated from the reaction interface to control the starting or closing of the aluminum hydrolization reaction;and the hydrogen produced during aluminum hydrolization under the action of the amalgam is led out through the hydrogen outlet. The aluminum hydrolization hydrogen production device and the controlling method thereof have the advantages of simple structure, convenient operation, good controllability, wide application scope, less power consumption and less pollution, and are especially applicable to the application of portable fuel cell power systems.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production, and in particular relates to an aluminum hydrolysis hydrogen production device and a control method thereof. Background technique [0002] Hydrogen has many uses in modern industry, such as metallurgy, chemical industry, food, experimental instruments and other industries have widely used hydrogen. As an excellent energy carrier, hydrogen can be directly burned to generate energy, and its product is water without any environmental pollution; it can also be generated by fuel cells. In the field of renewable energy applications, utilizing the storable properties of hydrogen can greatly improve the utilization efficiency of wind energy and solar energy. [0003] At present, the main methods of hydrogen production are 1) hydrogen production by electrolysis of water; 2) hydrogen production by reforming methods such as methanol, gasoline or natural gas; 3) hydrogen production from biomass;...

Problems solved by technology

Due to the use of caustic strong alkali in the hydrogen production process, the system complexity is increased, and the reaction products are also difficult to handle

Aluminum surface amalgamation is also an effective way to improve the hydrolysis reaction activity of metal aluminum, but in the published literature reports, due to the difficulty of controlling the reaction process, it is impossible to obtain the stable hydrogen flow required for the application
