Abstract
Relatively uniform spherical shaped solid pellets (prills) may be created by passing molten sulfur through a nested strainer to remove particles that would otherwise become trapped in the system, a drip tray with a heating channel attached on its underside, an injection conduit for delivery of a cooled zone of water to create solid prills, and thereafter moving the prills through a stationary curved screen to remove most of the excess water and a vibrating screen.
Claims32
A system for converting molten sulfur to sulfur prills, comprising:
- a heated removable strainer for removing non-sulfur particles from the molten sulfur;
- the removable strainer coupled to a drip tray;
- a first conduit attached to the drip tray for heating the drip tray;
- the molten sulfur traversing to the drip tray forming sulfur droplets;
- a tank storing a liquid media, said liquid media comprising a first media and a second media;
- a second conduit inside the tank for delivering the first media to a first area of the tank;
- a third conduit for delivering the second media to a second area of the tank;
- the sulfur droplets traversing a distance from the drip tray to the liquid media in the tank;
- and
- relatively spherical shaped sulfur prills formed by the interaction of the sulfur droplets with the media.
A forming tank for manufacturing sulfur prills, comprising:
- a tank having a top section and a bottom section;
- said top section having a cross sectional circular shape and said bottom section having walls converging with respect to one another to at least partially define a funnel shape;
- a first conduit inside the tank for injecting a first liquid media into the top section of the tank, said first liquid media creating a sulfur prilling formation zone in the tank;
- a second conduit for injecting a second liquid media into the bottom section of the tank, wherein molten sulfur droplets entering the tank in the formation zone forming the sulfur prills;
- and
- the sulfur prills exiting from the tank through an tank output port attached to the bottom section of the tank.
The forming tank of 13, wherein the tank output port having a cross sectional rectangular shape.
A system for converting molten sulfur to sulfur prills, comprising:

- a second conduit for delivering the second media to a second area of the tank;
- the sulfur droplets traversing a distance from the drip tray to the liquid media in the tank;
- and
- relatively spherical shaped sulfur prills formed by the interaction of the sulfur droplets with the media.
