Hydrogen production system

Abstract

The embodiment of the invention discloses a hydrogen production system which comprises a hydrogen production device. The hydrogen production device comprises a steam generator, wherein a steam generation assembly is arranged in the steam generator, the steam generation assembly is sleeved with a hot waste gas heating cylinder, and a hot waste gas channel is formed between the hot waste gas heatingcylinder and the steam generation assembly, a hot waste gas input port and a waste gas output port which are communicated with the hot waste gas channel are formed in the hot waste gas heating cylinder; a hydrogen generator which is internally provided with a hot waste gas transmission channel; a steam conveying pipe, wherein the steam generation assembly is communicated with the hydrogen generator through the steam conveying pipe; the steam generator comprises a liquid inlet header, and the liquid inlet header comprises a first flange plate arranged at the end of the hot waste gas heating cylinder, and a second flange plate which is matched and connected with the first flange plate to form the liquid inlet header. The hydrogen production device solves the problem of energy waste due to the fact that heat of waste gas is not recycled in an existing hydrogen production device.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a hydrogen production system. Background technique [0002] Hydrogen is a renewable energy source with a wide range of sources, including water, natural gas, methanol, ethanol, biomass, etc. Due to the energy depletion and environmental pollution caused by fossil fuels, people's desire for clean energy is becoming more and more obvious. Hydrogen energy has a high combustion calorific value, and the product is non-polluting. It is a clean and sustainable energy source. The current hydrogen production methods mainly include hydrogen production by steam and hydrogen production catalyst reaction, hydrogen production by reforming fossil fuels, hydrogen production by electrolysis of water, hydrogen production by photohydrolysis, biological hydrogen production and plasma hydrogen production. [0003] However, the existing hydrogen production device for hydrogen production ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the embodiment of the present invention provides a hydrogen production system, which effectively solves the problem of energy waste caused by the fact that the hydrogen production device in the existing hydrogen production system does not recycle the heat of the exhaust gas, and the small liquid inlet formed by setting the flange Chamber, while meeting the liquid inlet requirements, reduce the size of the steam generating device as much as possible and reduce the floor area. In addition, it can also reduce its capacity, reduce its capacity pressure, and reduce the number of regular inspections
