Abstract: A continuous wet ball-milling separation device has a cylinder, which has a feeding section, a shearing section, and a crushing section in sequence from top to bottom. The feeding section is located at the upper portion of the device, and is provided with a liquid inlet, a material inlet, and a material distributor. The shearing section is located in the middle of the device, and is internally provided with shearing blades. The crushing section is located at the lower portion of the device, and is internally provided with stirring rods and crushing balls, and a grading discharge module is provided at the bottom of the crushing section. A grading discharge module is used in the device and a continuous wet ball-milling separation method applying the device. The device implements continuous operations of material crushing and grading by means of the material distributor, wet shearing, wet crushing, and wet grading.

Abstract: An apparatus, a process and a system for treating petroleum coke are provided. The apparatus includes an activation unit that is an annular furnace reactor. The system includes a first reactor, the apparatus as a second reactor, a washing and separating unit, a cooling unit, a dissolving and separating unit, a washing and drying unit, optionally a regenerating unit, optionally a drying and calcining unit and optionally an evaporation-crystallization unit. The process for producing carbon materials uses the system for treating petroleum coke. The apparatus, the process and the system can achieve continuous production, and have advantages of high activation efficiency and stable properties of the resultant carbon material products.

Abstract: A production system for insoluble sulfur includes a polymeric kettle having a first discharge port and a quench tower (200) 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.

Abstract: A dividing wall column (10), comprising: a partition plate (11) arranged along an axial direction of the dividing wall column (10); a first shaft (22) arranged along a radial direction of the dividing wall column (10), and a first splitter plate (23) with an end connected to the first shaft (22), which are both placed beneath the partition plate (11), wherein the first splitter plate (23) is configured to be pivotable around the first shaft (22), so as to control distribution of a stream from below the first splitter plate (23) into spaces formed at two sides of the partition plate (11); and a second shaft (13) arranged along the radial direction of the dividing wall column (10), and a second splitter plate (20) with an end connected to the second shaft (13), which are both placed above the partition plate (11), wherein the second splitter plate (20) is configured to be pivotable around the second shaft (13), so as to control the stream from above the second liquid splitter plate (20) into the spaces formed a
