Sulfur granulator system and method

摘要

Sulfur (or sulphur) spray nozzles disposed with a tank spray liquid molten sulfur into the cooling liquid in the tank. Solid sulfur seeds are formed in the cooling liquid and settle in the tank. The tank may be a spiral dewaterer tank that has a screw conveyor at the bottom of the tank that moves the seeds to a granulating drum for enlargement into sulfur granules. The tank may also he used to capture and remove sulfur dust from a slurry of sulfur dust and water recycled from the granulating drum. The sulfur dust in the cooling tank may be captured by contact with molten sulfur droplets streaming down the cooling liquid column such that the dust particles become incorporated into the droplet, thereby being converted to seed. The granulating drum may be equipped with two or more sets of segmented lifting flights. The sets of flights may not be in alignment. The flights may be spaced apart from the inside surface of the drum with segmented rib members. The rib members may allow for the movement of sulfur seeds and granules between the nights and the inside surface of the drum as the drum rotates.

主权项

1. A system for converting molten sulfur into sulfur granules, comprising:
a tank for storing a fluid; a first nozzle disposed within said tank, the first nozzle in fluid communication with a liquid sulfur supply line; a granulating drum having an interior diameter surface, the granulating drum coupled to the tank and rotatable around a longitudinal axis extending from a first end of the drum to a second end of the drum; and a plurality of sets of lifting flights, each set disposed circumferentially around the interior diameter surface; wherein the individual lifting flights in the sets of lifting flights are segmented by having a length that is less than an axial length of the drum.
