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.

Production system and method for insoluble sulfur

A dividing wall column (), comprising: a partition plate () arranged along an axial direction of the dividing wall column (); a first shaft () arranged along a radial direction of the dividing wall column (), and a first splitter plate () with an end connected to the first shaft (), which are both placed beneath the partition plate (), wherein the first splitter plate () is configured to be pivotable around the first shaft (), so as to control distribution of a stream from below the first splitter plate () into spaces formed at two sides of the partition plate (); and a second shaft () arranged along the radial direction of the dividing wall column (), and a second splitter plate () with an end connected to the second shaft (), which are both placed above the partition plate (), wherein the second splitter plate () is configured to be pivotable around the second shaft (), so as to control the stream from above the second liquid splitter plate () into the spaces formed at two sides of the partition plate ().
