摘要： A continuous production device and a continuous production method which are configured to produce a polymer and can efficiently advance solution polycondensation with a simple device configuration which is easy to wash and maintenance. A continuous production device (100) includes a reactor main body (1), divider plates (6a to 6c) configured to divide the interior of the reactor main body into a plurality of reaction vessels (2a to 2d), and a raw material supply unit. The divider plate has a rotation center. Gas-phase parts of the reaction vessels adjacent to each other are communicating with each other, and liquid-phase parts of the reaction vessels adjacent to each other are communicating with each other. A reaction mixture generated in the reaction vessel sequentially moves through the reaction vessels.

摘要： A method of manufacturing core-shell particles comprises: filling a buffer into a rotor, which is extended in a longitudinal direction, and is accommodated so as to be spaced apart from an inner wall side of a non-rotational hollow cylinder extended in a longitudinal direction and then discharging air to outside; rotating the rotor after terminating the filling; forming a core-shell precursor by supplying raw materials from a first storage and a second storage, which comprise a material forming a core, into an interior of the cylinder in which the rotor rotates; supplying a shell material for coating the core to the interior of the cylinder in which a core-type precursor is formed; separating a liquid comprising core-shell particles formed through the supplying into a solid and a liquid; and drying the core-shell particles obtained through the separating.

摘要： A vertical autoclave according to an embodiment of the present disclosure is a vertical autoclave including an inlet port through which a process solution is introduced, an outlet port through which the process solution is discharged, an oxygen inlet port through which oxygen is supplied to the process solution, an agitator configured to mix the process solution, an inner wall, an acid-resistant brick layer lined on a lower portion and a side portion of the inner wall, and an acid-resistant metal layer lined on an upper portion of the inner wall. A method of removing salt from an autoclave includes raising a surface level of a solution in the autoclave from a first level to a second level such that salt in the autoclave is immersed in the solution, and maintaining the surface level of the solution at the second level. The salt is dissolved in the solution while the surface level of the solution is maintained at the second level.
