Apparatus for removing gaseous components and/or solid impurities from a gaseous fluid flow includes a frame structure in which are disposed a fluid flow inlet connector through which the gaseous fluid flow is charged into the frame structure, a scrubber, a discharge connector through which the purified fluid flow is discharged from the frame structure and a connector through which scrubbing liquid is introduced into the apparatus and contacted with the fluid flow. The fluid flow inlet connector has an end region adjacent to the scrubber which diminishes in cross-sectional diameter for accelerating the velocity of the gaseous fluid flow prior to the latter entering the scrubber and is also provided with openings through which a return flow of the scrubbing liquid can enter into the inlet connector, the openings being formed in a region of the inlet connector where the velocity of the fluid flow remains unaccelerated and shaped and disposed to direct the scrubbing liquid return flow in said inlet connector in a direction opposite to the direction of gaseous fluid flow so that the scrubbing liquid return flow is prevented from being entrained with the fluid flow. In this manner the scrubbing liquid return flow passes through the inlet connector in a direction opposite to the direction of the fluid flow to accomplish a pre-purification thereof.
