Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production by hydrolysis, in particular to a unit with adjustable aluminum hydrolysis hydrogen production rate and its integrated framework. Background Art

[0002] The regulation of hydrogen production speed can help optimize the operation efficiency of the hydrogen production system; by controlling the hydrogen production speed, it can ensure that the system operates under the best working conditions, thereby improving the overall energy conversion efficiency and the stability of hydrogen production, and avoiding the increase of safety hazards due to excessive hydrogen;

[0003] At present, in the process of hydrogen production by aluminum-water reaction, a dynamic control strategy is usually adopted to regulate the reaction rate, that is, the fine adjustment of the hydrogen generation rate is achieved by precisely controlling the addition amount of reactants; this method helps to maintain the reaction in a relatively stable and controllable state, ensuring the continuous supply of hydrogen and improving the reaction efficiency; however, once the reactants are put into a closed reaction vessel, due to the spontaneity and exothermic nature of the reaction, it is difficult to immediately terminate once started; this means that even when it is necessary to stop hydrogen production, the aluminum and water mixture that has participated in the reaction will continue to react until all reactants are exhausted or the temperature of the reaction system is low enough to significantly slow down the reaction rate; this non-instantaneous stop reaction state may lead to the production of more hydrogen than expected, thus increasing the equipment overpressure and potential safety risks. Therefore, this application provides a unit with adjustable aluminum hydrolysis hydrogen production rate and its integrated framework. Summary of the Utility Model

A feed pipe 211 and an exhaust pipe 214 are connected to the top of the reaction tank 21. The reaction tank 21 is connected to a water storage tank 41 through a water supply pipe 43. A water injection pipe 42 is connected to the upper end of the water storage tank 41. A filter screen 23 for intercepting aluminum raw materials is fixedly installed in the middle side of the interior of the reaction tank 21. A maintenance cover 22 is detachably arranged on the side of the reaction tank 21 so as to install the filter screen 23 in the reaction tank 21.
