Abstract
The invention relates to an appparatus where the wet scrubbing of several different gas flows is carried out in at least three scrubbing towers, and the droplet separation of scurbbed gases takes place in a cyclonic, uniform droplet separator constructed of several cylinders, so that the obtained product is a pure and droplet-free gas.
Claims14
An apparatus for scrubbing several different with liquid, at least in three scrubbing tubes (1), and for separating droplets from the scrubbed gases in a droplet separator, characterized in that the scrubbing tubes (1) are symmetrically opened to a scrubbing chamber (4), which is formed of a space confined by an outer cylinder (2) and a distribution cylinder((3) located therein, and that inside the scrubbing chamber (4), there are provided inwardly turnable partition walls (6) extending in the vertical direction from the ceiling of the scrubbing chamber (4) to below the liquid surface, the number of these partition walls being the same as that of the scrubbing tubes;
- that horizontally the partition walls extend from the outer cylinder (2) to the distribution cylinder (3), and set the gas flowing into the scrubbing chamber (4) in whirling motion;
- that inside the distribution cylinder (3) there is concentrically installed another inner cylinder (9), extending at the bottom to above the scrubbing liquid surface and forming an aperture for the whirl flow, in order to intensify droplet separation, as well as a concentric drain cylinder (11) arranged to rise upwards from the top of the inner cylinder (9);
- through this drain cylinder (11), the scrubbed, droplet-free gases are drained.
