Arranged at the outer periphery of the' rotor are fan blades'21, any number'of which maybe providedV and these blades are supported by being preferably secured to the annular members 18.

At the outer periphery of the forward face ofthe fan blades 21 projections 22 are provided and these projections are preferably of a tapered formation being spaced from each other laterally as at-23 to formlopenings or spaces therebetween Ywhich gradually reduce towardtheedge of the fan blade and terminate in restricted openings so that the mist orvrnoisture in the gas -w-ill-be caught by the fan blades and will" bei-,forced through the openings 23 thereby causing the particles of f mist to cohere to be thrown outwardly from the edges of thefanjblade's'through the openings23'.V

The fan blades also servek as a means to overcome drop in pressure through the washingweleme'nt, JQ i lThe cleaning meda such as water may be `admitted intojtheyhousingthrough suitable Vpipes 24: on either side ofxtheshaft 13, and theydisc landis discharged into a casing 25fwhich rotates1 withthe shaft13 being sup' .ported and connected thereto inv anyesuitzi able manner.

The internal diameter of the casingA 25 is .considerably greater than the external diameter of the shaft 13 soas to `form a chamberinto-whichfthe washing media-is delivered and which is discharged, as the leasing 25 rotates with the disc. 16 and shaft 13,-.through tubes or passages 26 .to bev directed against the frusto-conicalf members y19 .and therebetween. y

It will* also be manifest that with this construction-there is provided extended sur-A faces overV which 'the 'mixture passes and :by contact therewith and by means of the friction causedtherebetween .the water Willbe thrown `out .or projected from the conical members in a substantially solid stream. through which the gaswill, be directed.

By .arranging .the seriesofconical members with angles of. inclination in different directions, it will be manifest that the direction of flow ofthe gas andv Water as it passes from one series of deflector-members to the nextV series will be changed annmber of times. during their flow ,between the successlve series of deflector members.`

In testimony whereof I have signed my name to this speciication, on this 11th day of April, A. D. 1930.
