| titleOfInvention | Precipitation reactor for producing ultra-fine cerium carbonate |
| abstract | The invention relates to liquid-liquid mixing reaction precipitation devices, and in particular relates to a precipitation reactor for producing ultra-fine cerium carbonate. A main body of a kettle body is a cylinder body, wherein the lower end of the cylinder body is closed to form an inverse truncated cone shape, and the central part of a seal head at the bottom of the kettle body adopts an internal cone shape. According to the precipitation reactor disclosed by the invention, fluids in upper and middle areas form axial circulation, and the fluid in a bottom area of a crystallizer forms radial circulation so as to ensure that the crystallizer is large in internal circulation quantity and relatively short in mixing time, the shearing rate can be significantly increased, and micro-mixing and micro mass transfer of liquid-liquid phase reaction materials can be enhanced; areas with poor mixing cannot exist, deposited dead angles cannot be formed at the bottom, and precipitation particles are high in suspension efficiency and relatively uniform in distribution of solid hold-up; and good stirring effects can be achieved under relatively small stirring power, and the energy consumption can be reduced. Cerium carbonate prepared by using the precipitation reactor disclosed by the invention is relatively fine in particle size, narrow in particle size distribution range and relatively low in cost, and is suitable for industrial application. |
