Abstract
Apparatus for producing relatively large and dense, relatively dry sulfur particles from molten sulfur comprises a manifold having a number of small, spaced apart, molten sulfur discharge apertures which are sized, according to the rate and pressure head at which the molten sulfur is received, for enabling the sulfur flow from each aperture to be laminar. Included is a vessel for holding a quenching liquid, preferably water. The manifold is mounted above the vessel with the discharge apertures preferably about one quarter inch to about two inches above the quenching liquid surface. Means are included for continuously moving the manifold in a circular path while the moltlen sulfur is discharged from the manifold apertures so that the discharged streams continually contact different regions of the quenching liquid. A conveyor is connected to the vessel for removing particulate sulfur therefrom. Three stages of quenching liquid removal are provided, the first comprising a screen element, the second comprising a porous conveyor belt with an air blower, and the third comprising a conveyor belt with another air blower. Means are provided for adding quenching liquid into the vessel, witho…
