Abstract
This invention relates to a cascade-type scrubber, with which the wet scrubbing of the exhaust gas and removal of droplets from the gas can be performed in one and the same scrubber, producing a pure, dropless gas. It is thus essential that the cascade tubing typical of the cascade scrubber and the equipment for droplet removal are combined into a single compact entity, which is formed of several nested chambers.
Claims14
A cascade scrubber for scrubbing exhaust gas, whereby the scrubber contains several cascade tubes for scrubbing gas, an inlet channel for conveying the gas to the scrubber, a discharge tube for venting the gas from the scrubber and a liquid tank for scrubbing the gas, characterized in that a gas scrubbing unit and a droplet separation unit are combined in the scrubber into a compact apparatus, made up of several nested chambers, and that the cascade tubes are placed in an annular outer chamber surrounding said tubes, where the separate gas flows coming from each cascade tube are recombined.
