Full cycle production method for producing carbon disulfide from insoluble sulfur

The invention relates to a full cycle production method for producing carbon disulfide from insoluble sulfur. The method is characterized in that liquid sulfur is gasified to generate gaseous sulfur; the method mainly comprises a gasification step, a polymerization, quenching and ageing continuous main reaction step, a solid and liquid separator filtering step, a drying step, and a powder discharge step, and carbon disulfide is adopted as a loop initiating terminal from a main reaction, undergoes continuous reaction-solid and liquid separation filtering adjustment-drying-return to the main reaction as a first cycle loop, and undergoes continuous reaction-solid and liquid separator pumping filtration separation-evaporation cooling to recovery tank-solid and liquid separator cycle extraction pumping filtration-return of carbon disulfide to the main reaction as an extract coolant in order to form a second cycle loop, so high efficiency loop of carbon disulfide in the production process is guaranteed. The full cycle production method for producing carbon disulfide from insoluble sulfur has the advantages of high production efficiency, high repeated use rate, and good continuity.
