Abstract

The invention provides hydrogen production method and device based on an aluminum or magnesium underwater stir friction welding process, relating to hydrogen production method and device. The invention aims to solve the problems of complex process and environmental pollution of the traditional biological hydrogen production method and necessary addition of chemical agents or alloy elements in both the traditional electrolytic water hydrogen production method and the traditional chemical reaction hydrogen production method. The method comprises the following steps of firstly, installing a welded aluminum plate or a welded magnesium plate; secondly, injecting water; thirdly, selecting parameters of a welding tool; fourthly, installing the welding tool; fifthly, installing a hydrogen collection component; sixthly, carrying out stir friction welding on the welded aluminum plate or the welded magnesium plate; and seventhly, generating hydrogen when carrying out chemical reaction on the welded part of the aluminum plate or the magnesium plate and water in the stir friction welding seam forming process, continuously generating the hydrogen, collecting the hydrogen into a collection cover, and finishing hydrogen preparation by introducing the hydrogen into a storage container through an airway. In the device, a stainless steel cushion plate is arranged at the bottom of a water groove, the hydrogen collection component is arranged above the stainless steel cushion plate, and the collection cover is vertical to the stainless steel cushion plate. The invention is used for preparing hydrogen.

Description

technical field [0001] The present invention relates to a hydrogen production method and device. Background technique [0002] Hydrogen energy is an efficient and clean energy source. Due to its strong renewable ability, low environmental pollution and large heat production, hydrogen energy has received more and more attention in recent years for its research and application. Existing hydrogen production methods include biological hydrogen production, water electrolysis hydrogen production and chemical reaction hydrogen production. Biological hydrogen production is the use of activated sludge to ferment organic matter in organic wastewater to produce hydrogen-containing fermentation gas, which is eluted by lye. After the carbon dioxide is removed from the tower, hydrogen is produced. This method is complicated in process, pollutes the environment, has a low conversion rate of hydrogen production, and has high cost; the existing hydrogen production by electrolysis water and c...
