A
continuous production method of insoluble
sulfur comprises the steps of
sulfur melting, extraction, curing, crushing and
drying. The
continuous production method of insoluble
sulfur is carried out under a totally closed condition. The method concretely comprises the following steps: 1, placing sulfur in a sulfur melting
pool (1), melting, pumping the molten sulfur to a heating coil tube (3) through a
metering pump (2), heating, and mixing high-temperature sulfur with low-temperature
carbon disulfide in an ejector (4) to complete
quenching; 2, letting the quenched mixed liquid comprising insoluble sulfur and
carbon disulfide into a continuous-rotation
rotary kiln (6) through a rotary joint (5) to form a mixed liquid containing cured insoluble sulfur particles and
carbon disulfide; 3, conveying the mixed liquid obtained in step 2 to a crushing pump (8), and crushing; 4, sending the mixed liquid containing crushed insoluble sulfur and carbon disulfide to a material crushing pot (9), and carrying out
solid-liquid separation through a filter screen; and 5, sending insoluble sulfur to a vacuum dryer (10), and
drying. The method has the advantages of
continuous production of the insoluble sulfur under the totally closed condition, safety,
environmental protection, stable product quality, high efficiency, and low
energy consumption.
