The invention discloses a conveying method of oxidized tail gas of titanium white by adopting a chlorination method. In the conveying method, a connecting pipeline between a molten salt chlorination furnace and gas-solid separation equipment is provided with an automatic tail gas pressure control valve group; a pressure sensor is arranged on the connecting pipeline positioned behind the outlet ofthe automatic tail gas pressure control valve group and is used for detecting the pressure of the outlet of the gas-solid separation equipment; and a DCS (distributed control system) is adopted to regulate the output openness of the automatic tail gas pressure control valve group according to the pressure of the outlet of the gas-solid separation equipment detected by the pressure sensor so as tolead the tail gas pressure to be maintained between 200KPa-300KPa. In the method, the pressurization and conveying of tail gas of a chlorine compressor are omitted, and the DCS and the automatic pressure control valve group are utilized to regulate and balance the oxidizing tail gas and the pressure of a gas inlet of a chlorination furnace, and further realize smooth conveying of the oxidizing tail gas; the phenomenon of chlorine leakage caused by adopting the chlorine compressor is avoided, the pressure in the whole conveying process of tail gas is smooth, and simultaneously, the operating process of tail gas conveying is greatly simplified; and in the whole conveying process, the operation is simple, the labor is saved and the consumption of the original auxiliary materials is reduced.
