Abstract

The invention relates to the field of reformers, in particular to a spiral reformer. Including shell, first coil pipe, reaction storehouse, the base, burning tail gas export, burning methanol inlet and combustion unit, the methanol water gets into first coil pipe through the reaction methanol inlet and recirculates to the reaction storehouse in, because the inside passageway of reaction storehouse is continuous spiral path form, the methanol water carries out the reaction stroke with the catalyst of placing in the reaction storehouse and increases, can guarantee that methanol water and catalyst fully react, burning methanol inlet then carries burning methanol water to the combustion unit, the combustion unit during operation releases a large amount of heat, its heat is absorbed by first coil pipe and reaction storehouse for burning methanol water fully atomizes when the first coil pipe and reacts with the catalyst again, produce a large amount of hydrogen and discharge through the hydrogen-rich outlet after the reaction is accomplished, the tail gas after burning methanol burning then discharges through burning tail gas export.
