In order to improve the operation safety and avoid the volatilization and loss of a large amount of solvent, domestic enterprises mostly adopt an intermittent production process; namely, the tank body is kept still and is connected with a pipeline, and the material pipeline connected with the tank body is disassembled after the tank is quenched and filled with materials. And (3) separating the material tank from the quenching pipeline after the tank is full, independently carrying out standing liquid drainage, rotary crushing, curing and washing, drying, solvent recovery and the like on the material in the tank, and standing the tank body after the material in the tank meets the process requirements. And opening the manhole cover, and rotating to discharge.

After each tank IS operated one unit operation, the inert gas replacement, the quenching material receiving and the surplus solvent discharging are repeatedly carried out, and then the rotating and standing exchange treatment IS carried out for a plurality of times, so that the semi-finished product of the insoluble sulfur (IS90) material which meets the requirements can be discharged.
