Abstract: A washing tower for the washing of gases containing particulates comprises a packed bed through which the gases pass upwardly and jets for spraying water into the gas as it rises within the tower. A preferably chevron-shaped coarse droplet separator is provided above the spray nozzles and the bed and consists of upper and lower arrays of oppositely inclined plates. Further spray nozzles are provided above the coarse separator and above these spray nozzles is disposed a fine-particle separator of the baffle type through which the gas is deflected in opposite directions and with passages of smaller width than those of the coarse particle separator. The gas emerges from the upper end of the tower.
