The invention relates to a short stage recycle hydrogen desulfurization method and a device, and provides a short stage recycle hydrogen desulfurization method which comprises the following steps: (a) dealkylation is carried out to gas mixture of the recycle hydrogen so as to separate disperse phase heavy hydrocarbon liquid drops out of continuous phase recycle hydrogen and obtain a mixed phase of a heavy hydrocarbon phase and the recycle hydrogen containing sulfur; (b) the obtained mixed phase is further separated so as to remove the sulphide therein and obtain sulfur-free recycle hydrogen; and (c) the obtained sulfur-free recycle hydrogen is further separated so as to remove the amine liquid therein and obtain purified recycle hydrogen. The invention also provides a short stage recycle hydrogen desulfurization device.
