The invention discloses chloride-process titanium dioxide production equipment which comprises a cyclone separator, a condenser, an air blowing device and a variable-frequency motor, wherein the condenser is connected with the cyclone separator; the air blowing device is connected with the condenser so as to blow air to the condenser; the variable-frequency motor is connected with the air blowing device so as to drive the air blowing device to work; and the variable-frequency motor is linked with the pressure of the cyclone separator. According to the chloride-process titanium dioxide production equipment of the embodiment of the invention, the variable-frequency motor is linked with the pressure of the cyclone separator so that the pressure of the cyclone separator is maintained at a normal state so as to guarantee the separation effect of the cyclone separator and the normal operation of the condenser and further guarantee the quality of titanium tetrachloride. The pressure of the cyclone separator is maintained at a normal state so that steam in dust slurry hardly enters the cyclone separator, thus pipeline blockage is reduced and the normal operation of a titanium tetrachloride production system is future guaranteed. Therefore, normal production of the titanium dioxide is guaranteed.
