Titanium alloy methanol-water reformer and hydrogen production device

Abstract

The invention discloses a titanium alloy methanol-water reformer and a hydrogen production device. The reformer comprises a titanium alloy shell, a titanium alloy reforming cavity, a titanium alloy vaporization coil pipe, a titanium alloy purification device and a combustion chamber; the titanium alloy reforming cavity is arranged in the titanium alloy shell and comprises a cylindrical outer cavity wall and a cylindrical inner cavity wall, a cavity between the cylindrical outer cavity wall and the cylindrical inner cavity wall is a methanol-water reforming hydrogen production cavity, and a cylindrical through hole penetrating up and down is formed in the cylindrical inner cavity wall; the titanium alloy vaporization coil pipe is arranged in the cylindrical through hole and is provided witha middle hole penetrating up and down; the titanium alloy purification device is mounted in the middle hole; a space is formed between the titanium alloy purification device and the titanium alloy vaporization coil pipe to form a combustion chamber. The reformer is light in weight, high in strength, small in wall thickness, not prone to corrosion, capable of forming an embrittlement layer and high in hardness, and trace CO impurity components of the titanium alloy purification device are reduced; meanwhile, the overall structure is reasonable, the reforming hydrogen production efficiency is high, and the energy utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of methanol water hydrogen preparation equipment, in particular to a titanium alloy methanol water reformer and hydrogen production equipment. Background technique [0002] Hydrogen is one of the most ideal energy sources in the 21st century. When burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water without ash and waste gas. pollute the environment; while coal and oil combustion mainly produce CO 2 and SO 2 , which can produce the greenhouse effect and acid rain respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which can continuously produce hydrogen and never run out. The distribution of hydrogen is very wide, and water is a large "warehouse" of hydrogen, which contains 11% hydrogen. There is about 1.5% hydrogen in soil; oil, co...

AI Technical Summary

Problems solved by technology

However, in the prior art, the reformer of methanol-water hydrogen production equipment still has the following deficiencies: first, it is made of stainless steel, which is heavy in weight, low in strength, and has a wall thickness of about 2mm; second, the traditional reformer is easily damaged Corrosion; third, in the reforming chamber and purification device, it cannot be mixed with H 2 The formation of an embrittlement layer increases the strength of the wall; third, the structure and layout of the traditional reformer shell, reforming chamber, vaporization coil, purification device, and combustion chamber are not reasonable enough, and methanol water raw materials are difficult to be efficiently utilized, and energy utilization rate is not high enough
