Method and system for generating sulfur seeds in a moving liquid
Sulfur seeds may be produced by spraying liquid molten sulfur from a sulfur spray nozzle into a moving stream of liquid. Some of the sulfur may pass through the liquid and some of the sulfur may be entrained in and transported by the stream of liquid, or all of the sulfur may be entrained in the stream of liquid. The sulfur droplets that are entrained in the stream of liquid may be carried by the liquid to a cooling tank, which may be a spiral dewaterer tank with an angled bottom and a screw conveyor. An opening may be made in the bottom surface of the screw conveyor housing of the spiral dewaterer tank for liquid to drain from the screw conveyor as it moves sulfur seeds from the tank to a the drum. A screen may be disposed across the opening, and a drain trough attached to the screw conveyor housing to capture any liquid and solids that move through the screen. A wash line may assist in moving solids that pass through the screen.
1. A method for converting molten sulfur into sulfur seeds used for enlargement into sulfur granules, comprising the steps of:
spraying the molten sulfur into a moving stream of liquid;
transporting the molten sulfur in the moving stream of liquid; and
forming sulfur seeds by an interaction of the molten sulfur with the liquid.
2. The method of claim 1 , wherein the molten sulfur is sprayed in the same direction as the moving stream of liquid.
3. The method of claim 1 , wherein the spray nozzle is positioned above the moving stream of liquid.
4. The method of claim 1 , wherein the liquid is water.
5. The method of claim 1 , wherein the moving liquid is not in a container at a time of the interaction with the molten sulfur.
6. The method of claim 1 , further comprising the step of:
pouring the moving stream of liquid from a trough before the step of spraying.
7. The method of claim 1 , further comprising the step of:
conveying the seeds to a cooling tank in the stream of liquid.
8. The method of claim 7 , further comprising the step of:
conveying the seeds out of the cooling tank to a sulfur granulating device.
9. The method of claim 8 , further comprising the step of:
enlarging the sulfur seeds into sulfur granules in said granulating device.
10. A method for converting molten sulfur into sulfur seeds used for enlargement into sulfur granules, comprising the steps of:
spraying the molten sulfur through a spray nozzle into a moving stream of liquid;
passing some of the sulfur through the moving stream of liquid;
transporting some of the sulfur in the moving stream of liquid; and
forming sulfur seeds by an interaction of the sulfur with the liquid.
11. The method of claim 10 , wherein the molten sulfur is sprayed in the same direction as the moving stream of liquid.
12. The method of claim 10 , wherein the spray nozzle is positioned above the moving stream of liquid.
13. The method of claim 10 , wherein the moving liquid is not in a container at a time of contact with the molten sulfur.
14. The method of claim 10 , further comprising the step of:
pouring the moving stream of liquid from a trough before the step of spraying.
15. The method of claim 10 , further comprising the step of:
conveying the seeds to a cooling tank in the moving stream of liquid.

a drain trough attached under said screw conveyor housing;
wherein said screw conveyor housing having an opening in a bottom surface that is covered with a screen.
17. The apparatus of claim 16 , wherein said drain trough is configured to transport liquid toward said cooling tank that moves through said screen.
18. The apparatus of claim 16 , further comprising:
a wash line attached with said drain trough;
wherein said wash line is configured to convey a liquid to said drain trough to transport solid particles that pass through said screen.
19. The apparatus of claim 16 , further comprising:
a drain trough line attached between said drain trough and said cooling tank;
wherein said drain trough line is configured to transport liquid and solids from said drain trough to said cooling tank.
20. A system for generating sulfur seeds, comprising:
a sulfur spray nozzle disposed with a cooling tank, the spray nozzle outputting molten sulfur;
a trough coupled to the cooling tank for collection and release of a stream of liquid;
