Abstract

PURPOSE: The titled apparatus intended for enhancement of blowing effect and prevention of trouble caused by asphalt mist, which comprises providing one or several dispersion plates in a liquefied asphalt layer in a reaction vessel having a gas-blowing zone at the bottom.
CONSTITUTION: In liquefied asphalt layer 4 in reaction vessel 1 having a gas-blowing zone 7 at the bottom, one or several dispersion plates 6 of diameter corresponding to 2/3W4/5 of the inner diameter of the reaction vessel 1, having a number of holes 11 20W50mm in diameter, are placed 200W500mm below the liquid surface, said several dispersion plates 6 being spaced at intervals of 100W300mm.
EFFECT: Increase in contact surface caused by the dispersion of a large foam into a small one, increase in contact time caused by reduction in rate of upward movement of the foam, uniform dispersion of foams and enhanced agitation effect are effected, so that a blown asphalt of uniform quality is obtd.
