Abstract: Apparatus and method for removing gaseous components and/or solid impurities from a gaseous fluid flow by introducing a first scrubbing liquid into contact with the gaseous fluid flow in a pre-purification section to pre-purify the same. The pre-purified gaseous fluid flow is then conducted to the region of the scrubber impeller in the fine-purification section with a second scrubbing liquid being introduced into contact with the pre-purified gaseous flow as the latter is conducted to the region of the scrubber impeller. The flow of the pre-purified gas is accelerated as it is conducted to the region of the scrubber impeller, such as through a conduit which tapers in cross-section in the direction of gaseous fluid flow therethrough. An extremely fine scrubbing of the gaseous fluid is obtained in a reliable manner without the need for large quantities of scrubbing liquid.

Abstract: 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.

Abstract: A gas-purifying device capable of removing solid and/or gaseous components from a flowing gas. The device includes a cyclone for receiving the gas and removing therefrom relatively coarse solid components, this cyclone having a tubular discharge having at an upper region in the interior of the cyclone a bottom open end through which the gas enters the tubular discharge after the relatively coarse solid components have been removed therefrom. Situated at least partly within the tubular discharge is a wet-washer for subjecting the gas flowing through the tubular discharge to a wet-washing action which removes from this gas relatively fine solid components and/or gaseous components, before the gas is discharged to the exterior of the cyclone.
