Manufacturing equipment and manufacturing process for spherical sulfur granules

Abstract

The invention discloses manufacturing equipment and a manufacturing process for spherical sulfur granules. The manufacturing process is characterized by comprising the following steps of: feeding liquid sulfur pumped by a liquid sulfur pump in a storage tank into a drum granulator through a jacket pipeline to perform granulation, compressing cooling water in a cooling water tank by a cooling water pump and then spraying the compressed cooling water into the drum granulator, and discharging the solidified sulfur granules into a product packing section from one end of the drum granulator; pumping sulfur dust into a water film dust remover by a draught fan in a water film dust removing unit to perform washing and dust removal; discharging the washed clean gas into the atmosphere; delivering the washed sewage containing the sulfur dust to a filter through a filter pump to perform filter treatment; circulating the filtered water to wash the sulfur dust; and delivering the filtered solid sulfur into the drum granulator to perform granulation so as to form large sulfur granules, and packing products. The manufacturing process has the advantages of solving the problem of sulfur dust reclamation during granulation, and preventing the sulfur dust from exploding and polluting the atmosphere. The manufacturing process has the characteristics of large production capacity, small floor area, saved investment, reduction of production cost and the like.

Description

technical field [0001] The invention relates to a spherical sulfur particle manufacturing equipment and a manufacturing process thereof, belonging to the technical field of chemical production equipment and processes. Background technique [0002] Sulfur is a by-product of oil production and desulfurization of natural gas. At present, the ways to deal with sulfur include: 1. Liquid sulfur is directly injected into the sulfur pool to solidify to form irregular large pieces, but dust will be generated during transportation to pollute the environment. 2. Send the liquid sulfur directly to the downstream factory with the insulated tanker. However, it is limited by the transportation distance and the capacity of downstream factories. 3. Using a steel belt granulator, see patents CN200420108449.1, CN99224713.6, CN200420030205.6, CN98238065.8. This device is restricted by two factors due to the limitation of the width of the steel strip and the two-dimensional plane distribution...

AI Technical Summary

Problems solved by technology

As a result, the maximum sulfur production capacity on the steel belt is only 6 tons / hour

Due to the large area occupied by this equipment, it is not suitable for sulfur granulation production occasions with an output of more than 6 tons per hour.
