Abstract

This invention provides an experimental apparatus for the hydrolysis of titanium oxysulfate, relating to the technical field of experimental equipment for titanium dioxide production. The apparatus includes: a volumetric flask support, an oil bath, a three-necked glass flask, a stirring device, a thermometer, and an acid mist absorption system. The oil bath conducts heat, and the opening of the heating device is adjusted via the thermometer to precisely control the heating temperature of the hydrolysate slurry between 110℃ and 125℃. The stirring device is equipped with a speed control for effective stirring of the slurry. The use of a cocked spherical volumetric flask allows for convenient replenishment of water, addition of hydrolysis-specific seed crystals, and control of the addition amount and flow rate. Simultaneously, a 15% alkaline solution is used to absorb the acid mist emitted after condensation, solving the acid mist pollution problem. This apparatus is comprehensive in function, integrating key control links in the hydrolysis process. It is easy to operate, greatly improving experimental efficiency and accuracy, and is particularly suitable for experimental research on titanium oxysulfate.
