The utility model discloses a
methanol reforming
hydrogen production device based on
solar energy and
tail gas utilization, which relates to the field of
new energy utilization and
chemical production and comprises a
solar heat collector and a
methanol reforming reactor. The
solar heat collector comprises a groove type
paraboloid collecting lens,
sunlight irradiates the collecting lens and is reflected to a focus point, and the
methanol reforming reactor is located at the
light reflection focus point of the groove type
paraboloid collecting lens; the methanol reforming reactor comprises an aluminum
alloy pipe, a
tail gas flow
pipe, a methanol reforming
pipe, a gas inlet pipe and a gas outlet pipe; the
tail gas flow pipe is nested in the aluminum
alloy pipe, a plurality of methanol reforming pipes are distributed in an interlayer between the tail gas flow pipe and the aluminum
alloy pipe, and the gas inlet pipe and the gas outlet pipe are communicated with all methanol reforming pipes; the aluminum alloy pipe absorbs heat generated by
sunlight, and the tail gas flow pipe absorbs
waste heat of tail gas circulating in the tail gas flow pipe to jointly supply heat to the methanol reforming pipe; methanol steam enters the methanol reforming pipe from the gas inlet pipe, reacts in the methanol reforming pipe to generate
hydrogen-rich reforming gas, and is discharged from the gas outlet pipe.
