<p>A washing device comprises an upper chamber containing a washing liquid and communicating with an enamel-spraying device and a lower under-pressure chamber. A nozzle is installed between those two chambers which has an inlet to receive the washing liquid and a gaseous mixture to be washed and an outlet communicating with the under-pressure chamber. The particle-containing gaseous mixture is drawn through the washing liquid atomized in the nozzle and is washed thereby. The nozzle has a cross-section of a bell-like configuration and is provided with edges at the outlet of the nozzle. These edges face toward the central axis of the casing and are provided with teeth whereby the surface of contact of the particles with the atomized washing liquid at the outlet of the nozzle is substantially increased and the distribution of the washing liquid at the outlet of the nozzle is improved.</p> |
