A production system for insoluble sulfur includes a polymeric kettle having a first discharge port and a quench tower () having a feed port. The first discharge port is in communication with the feed port. The quench tower has a cylindrical housing, a granulation device and a shear pump. A solvent inlet and a quenching agent inlet, which are respectively used for providing a solvent and a quenching agent, are arranged on the side wall of the housing. The sulfur production method includes raising the temperature of liquid sulfur under the protection of an initiator and nitrogen to perform polymerization reaction; introducing the polymerized material into the quenching tower and sequentially carrying out granulation and quenching treatment; carrying out solvent curing and extraction integrated treatment on the quenched product; and carrying out liquid phase circulating crushing and extraction integrated treatment on the cured and extracted product.
