Novel hydrogen generation control system of high-temperature continuous solid block hydrogen generation device

Abstract

The invention discloses a novel high-temperature continuous solid block hydrogen generation device hydrogen generation control system which comprises a hydrogen generation mechanism, the hydrogen generation mechanism comprises a solid hydrogen storage device, a hydrogen generation cabin and a reaction water storage tank, and a water outlet of the reaction water storage tank is connected with the hydrogen generation cabin through a pipeline with an electric control valve and a water pump. The solid hydrogen storage device comprises at least two magnesium hydride storage boxes arranged in a sealed cabin. Different from a hydrogen bottle hydrogen supply system, a whole-course low-pressure system is adopted, pipelines and devices can be made of non-metal products, and the lightweight degree is high; the reaction rate is controlled through solid block magnesium hydride with different particle sizes, so that more stable hydrogen production is realized; and the purified water can be repeatedly utilized and circulated into the water replenishing device to replace the water needing to be supplied, so that the water consumption is reduced.

Description

technical field [0001] The invention relates to the field of equipment for generating hydrogen, in particular to a novel hydrogen generation control system for a high-temperature continuous solid-block hydrogen generation device. Background technique [0002] As one of the methods of storing hydrogen, there is an occlusion alloy method. As an occlusion alloy method, since it does not need to store hydrogen in a special state such as ultra-high pressure and extremely low temperature, it not only has excellent characteristics of easy operation and high safety, but also has a high hydrogen storage capacity per unit volume. excellent features. In the 40239 Chinese Announcement No. 2013800326813, a hydrogen generating device using an occluded alloy method is disclosed. 40239 Chinese Announcement No. 2013800326813 relates to a hydrogen generating device having a cylindrical storage chamber for storing a mixed powder of magnesium-based hydride powder and acid powder containing ma...

Problems solved by technology

[0007] The hydrogen generation device of the prior art, the first one is to put the metal hydride into the hydrogen generation cabin at one time, and then mix it with the liquid reactant (water); the second one uses the feeding mechanism to continuously send the metal hydride into the hydrogen generation cabin Oxide, this method has the following problems: in order to generate hydrogen relatively stably, a high-precision feeding mechanism is required; whether it is a solid-liquid mixing pump or a screw feeding mechanism, in order to achieve reaction stability, an adjustable function must be realized. The logic and theoretical calculations are relatively complex, and it is necessary to meet multiple requirements such as real-time adjustment of the speed. If there is structural damage, there will be a major safety hazard; the working status of real-time products is not easy to achieve stability, which does not meet the requirements of productization
