  • Patent number: 4043717
    Abstract: A device for preparing granular sulphur particles from a stream of molten sulphur is disclosed. The device comprises an elongated conduit for moving the molten sulphur which has a uniquely designed spray head coupled at one end thereof. The spray head has a nozzle opening to discharge the sulphur. A helical member is disposed inside of the spray head adjacent the nozzle opening such that when the sulphur exits out of the spray head, it forms a deluge-type spray. A water jacket is circumferentially disposed about the sulphur conduit adjacent the spray head so as to form an annular orifice thereabout. The annular orifice is located behind the nozzle opening such that as the molten sulphur exits out of the spray head, it comes in direct contact with an annular water spray. Impingement of the water on the molten sulphur causes the sulphur to form into irregular granular pellets which are very porous.
