The invention discloses a process for continuously producing insoluble
sulfur by a pipeline. In the process, the insoluble
sulfur is produced by adopting the sealed pipeline, steps forming a flow for producing the insoluble
sulfur are sequentially performed on each section of the pipeline and corresponding
process conditions are provided for materials of each section of pipeline so as to realize the pipeline type
continuous production of the insoluble sulfur. The pipeline for producing the insoluble sulfur is divided into a pipeline sulfur melting section, a pipeline heating section, a pipeline
quenching section, a pipeline curing section, a pipeline washing section, a pipeline separation section and a pipeline
drying section. A sulfur
raw material enters the pipeline sulfur melting section, and is sequentially subjected to sulfur melting, heating,
quenching, curing, washing, separation and
drying, and finally, the insoluble sulfur is automatically discharged from the pipeline
drying section. The process is used for producing the insoluble sulfur, has the advantages of high quality of product, low cost, energy saving, environmental friendliness, safety and the like, and is applied to the continuous
mass production of the insoluble sulfur.
