The invention relates to a reverse extraction device and method for gas condensate fiber liquid membrane sulfur and alcohol removing and an alkali liquor regeneration solvent. The reverse extraction device comprises a first coalescence dehydrator, a first-stage liquid membrane contactor, a first-stage sulfur and alcohol removing separation tank, a second-stage liquid membrane contactor, a second-stage sulfur and alcohol removing separation tank, a gas condensate liquid membrane washing contactor, a gas condensate washing separation tank, an alkali liquor heat exchanger, a catalyst injection device, a first gas distributor, a tail gas washing dealkalization tank, a second gas distributor, a reverse extraction liquid membrane contactor, a reverse extraction separation tank, a reverse extraction solvent washing contactor, a reverse extraction solvent washing separation tank, a third coalescence dehydrator, a plurality of filters connected with one or more of the parts, a plurality of circulating pumps, a plurality of pipelines, a plurality of liquid inlets and a plurality of liquid outlets. The reverse extraction device and method have the advantages that design is reasonable, the sulfur and alcohol removing rate and the sulfur and alcohol removing alkali liquor regeneration efficiency reach 90% or higher, regenerated alkali liquor is good in quality, the alkali slag discharge amount is low, and more than 80% of sulfur and alcohol can be repeatedly applied to industrial production.
