Conic air swirler

U [cc,z r, D, .., U [ a,z r ) (Geometrical similarity). It is visible that the criterion C is defined by physical parametres of a dust-laden gas mix and specific productivity of a scrubber. The criterionC is defined by sizes of a conic air swirler and a slope of its guide vanes on which the relationship between tangential and radial speeds, and consequently, a relationship of an inertial force and force of resistance depends.

The bubbling—swirling apparatus with a conic air swirler according to Figure 20.16 contains the cylindrical chamber 1 with an entrance pipe 2, the axial sprinkler 3 perforated by holes of small diameter 4 and silenced with target end. 

The increase in altitude of a cylindrical part of a scmbber as well as decrease of an angle of a conic part of an air swirler, increases the dwell(ing) time of corpuscles in a zone of separation and raises the efficiency of clearing of gas emissions [9-12],... 

The increase in a slope of guide vanes or decrease of an angle of conicity of air swirler ATVC results thereto that the maximum of speeds at enough big intensity of blade twist moves more close to a spinning ax. 

The roll forming of an air swirler 7 on a conic spiral simultaneously with a stream twisting reduces possibility of a breakaway of dispersion particles and iheir ablation in a target pipe. Thus, drops of liquid with finely divided corpuscles with much smaller losses of ablation attain the sludge remover 11. The separated sludge is washed off by a liquid and by means of an inclination of the cylindrical chamber 1 is carried on a pipe of an overflow of sludge 10 in the sludge remover 11.
