According to reports, this new type of reaction device is named spherical stirred reactor with jacket, which makes the kettle body and jacket of traditional stirred reactor with jacket into a sphere. Because the spherical inner shell forms a 360-degree universal symmetric constraint space, the medium in the kettle can obtain more uniform axial, radial and three-dimensional flow fields in the whole volume under the stirring condition, so as to realize the uniform dispersion of gas, liquid and solid phases and realize the efficient and uniform mass transfer reaction without dead ends. Under the same material, pressure and temperature conditions, the wall thickness of spherical shell is reduced by half compared with that of cylindrical shell with the same diameter, which can proportionally reduce the thermal resistance of the wall and improve the thermal conductivity. When the volume and working conditions on both sides of the reactor wall are the same, the heat transfer capacity of the spherical reactor is about 1.5 times that of the cylindrical reactor. At the same time, due to the universal symmetry of spherical space distribution, the reactor can be used vertically, horizontally and obliquely. In terms of structural stress, it is especially suitable for the requirements of high temperature, high pressure and large volume equipment, and it is easy to be serialized and large-scale. In addition, the spherical kettle is more convenient for cleaning the kettle wall.
Reactor is the key equipment in any chemical production process, which determines the quality, variety and production capacity of chemical products. Stirred tank reactor is a widely used equipment. At present, there are two kinds of kettle reactors commonly used in chemical production, vertical and horizontal, but the kettle body structure is cylindrical, and the flow pattern of the fluid medium in the kettle is not completely uniform, or even there are dead ends, which adversely affects the heat and mass transfer of the reaction medium. However, the jacketed spherical stirred reactor successfully developed by Xindu Xing Kai Technology Co., Ltd. is still blank in the world. This spherical kettle technology has been included in the key scientific and technological research project in Chengdu in 2004, and at the same time, it has registered utility models and invention patents in the country.
