A production method of insoluble sulfur is characterized in that sulfur is heated as a raw material to 450-600 DEG C, the heated sulfur is introduced into a quenching column under 0.01-05 MPa, carbon disulfide is sprinkled to the upper portion of the quenching column, a containing precipitator loaded with carbon disulfide is extended into the bottom of the quenching column, an umbrella precipitating disc and a precipitating ring are arranged in the precipitator, a screw crystallizer and a stirrer are mounted at the bottom of the precipitator, the screw crystallizer is connected with a liquid crusher, the liquid crusher is connected with a pump, the pump is connected with a closed filter, solid filtered from the filter and part of carbon disulfide jointly enter a filtering washing drying combine, liquid from the filter enters a carbon disulfide tank, filtering, leaching and drying are performed for insoluble sulfur in the filtering washing drying combine, and the insoluble sulfur is oiled in an oiling machine.
