Abstract
A melt is passed as a flow into a space wherein the melt flow impinges against a deflecting surface transforming the melt flow into a thin, evenly spreaded film which, upon meeting one or more jets of a dispersing gaseous or liquid substance, is effectively dispersed.
Claims15
A method for dispersing a melt by means of a jet of at least one medium selected from the group of gaseous and liquid media, by causing the melt flow to impinge against a continuous laterally open deflecting surface in the dispersion space to form a thin, widening, laterally unconfined, film of the melt before it meets the jet of the dispersing medium.
An improved device for dispersing a melt by means of a jet of at least one medium selected from the group of gaseous and liquid media having a reactor, means for feeding a melt to be dispersed into the reactor;
- and means for spraying at least one substance selected from the group of gaseous and liquid dispersing media into the reactor towards the melt flow to disperse this flow;
- the improvement comprising feeding means for dispersing medium fitted in the reactor between the intersection point of the melt and the dispersing medium and the feeding point of the melt;
- and a continuous laterally open surface slanted in relation to the melt flow and directed away from the feeding means for the dispersing medium to spread this flow into an even and widening, laterally unconfined thin film before it meets the jet of the dispersing medium.
