A water-spray gas-scrubbing device of water-cooled metallic construction for use with a processing facility producing gases containing extractable particulate waste and having a conduit for the gases, and a gas-scrubbing chamber in which the combustion gases are washed with water sprays to remove particulate material. The washed gases are vented to the atmosphere and the scrubbing water passes downwardly through a series of metallic mesh filter trays in a filter tower to remove particulate material from that water which is then re-circulated to the scrubbing chamber. The conduit and the combustion chamber are formed as hollow metallic wall structures with inner and outer metallic walls, and cooling water flows continuously through those hollow wall structures to reduce thermal damage thereto.
