The invention discloses a pressurizing-type halogenated hydrocarbon tubular reaction system. The pressurizing-type halogenated hydrocarbon tubular reaction system comprises a mixing kettle, wherein a discharging end of the mixing kettle is connected with a metering pump, the metering pump is connected with a reaction pipe, and the discharging end of the reaction pipe is connected with a rectifying tower; the reaction pipe is wrapped by a heating sleeve, a heat inlet of the heating sleeve is connected with a heating pump, the reaction pipe comprises a pressure-bearing outer pipe body, and the inner wall of the pressure-bearing outer pipe body is provided with an anticorrosion layer. Raw materials halogen hydride and alcohols for preparing a halogenated hydrocarbon are placed and mixed in the mixing kettle, heated steam is pressed by the heating pump into the heating sleeve so as to heat the mixed raw material in the reaction pipe, the halogen hydride and the alcohols react to generate the halogenated hydrocarbon product, the discharging end of the reaction pipe continuously conveys the generated halogenated hydrocarbon product to the rectifying tower, and the halogenated hydrocarbon product is purified to obtain the pure halogenated hydrocarbon product. By adopting the pressurizing-type halogenated hydrocarbon tubular reaction system, the halogenated hydrocarbon product can be continuously produced, less manpower is used, the production scale is large, the yield and the production efficiency are high, and the controllability is high.
