AEROSOL SEPARATOR

摘要

The invention relates to an aerosol separator for separating dust aerosol and droplet aerosol, comprising a channel section which has a vertical or steeply inclined axis and contains the aerosol separator, into which waste gas flows from below. Said aerosol separator has at least one end spraying region covering the cross-section of the channel. In said end-spraying region, the through-flowing crude gas or waste gas is subjected to a mist of droplets of a volatile liquid and is guided into the supersaturated wet region. A bundle of tightly packed, similar, straight tubes of process-suitable or process-inert material, extending over the cross-section of the channel, is connected in the direction of flow. The liquid droplets fall on the inside and outside of the tubes of said bundle and flow off in the counter-flow on the outwardly concave surface of the tube bundle, on which they flow off towards the channel wall in a groove surrounding the inner wall of the channel, and are recovered via an outflow opening as a collected liquid containing impurities.
