Abstract

The invention discloses a hydrogen production system, comprising: a hydrogen production device comprising: a hydrogen production part provided with a steam input pipe and a hydrogen discharge pipe; the steam generation part that comprises a heating part, wherein the heating part is provided with a plurality of combustion heating pipes and liquid heating cavities in the outer sides of the combustion heating pipes, the bottoms and / or the tops of the combustion heating pipes are detachably connected, and combustion catalysts are arranged in the combustion heating pipes; a steam discharge pipe that is communicated with the top of the liquid heating cavity and the steam input pipe; a liquid leading-in pipe that is communicated with the bottom or the side surface of the liquid heating cavity; an overheating part that comprises a plurality of steam straight pipes, the bottoms of the steam straight pipes are communicated with the liquid heating cavity, and the tops of the steam straight pipes are communicated with the steam discharge pipe; a purification device that is communicated with the hydrogen discharge pipe, wherein the combustion heating pipe is used for introducing tail gas and the combustion catalyst to carry out exothermic reaction, and the liquid heating cavity is used for introducing liquid to prepare steam. The problem that the combustion catalyst is difficult to replace is solved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a hydrogen production system. Background technique [0002] With the extensive use of traditional fossil energy, air pollution is becoming more and more serious, and mineral resources are gradually depleted. Therefore, there is an urgent need for an environmentally friendly and efficient clean energy, such as solar energy, water energy, wind energy and hydrogen energy. Among them, the clean combustion of hydrogen is destined to be an ideal energy source. However, in the process of hydrogen production, its production environment needs to be strictly controlled. Once hydrogen leaks, it will cause serious safety accidents. [0003] In the existing hydrogen production process, there is a method of hydrogen production using methanol and water as raw material liquid. In the production process, the liquid raw material is first passed into the hydrogen production equipment, t...
