The utility model discloses a production device for preparing chloropropyl chlorosilane, which comprises a dripping tank, a reaction kettle, a reflux condenser and a freezing condenser, the outlet of the dripping tank is communicated with the inlet of the reaction kettle through a bottom-inserted dripping pipe, the top of the reaction kettle is communicated with the inlet of the reflux condenser, and the freezing condenser is communicated with the bottom-inserted dripping pipe. An outlet of the reflux condenser is communicated with an inlet of the freezing condenser through a gas phase pipe, and an outlet of the freezing condenser is communicated with an inlet of the dropwise adding tank through a pressure balance pipe; a hydrogen-containing chlorosilane inlet pipeline and a chloropropene inlet pipeline are arranged on the dropwise adding tank; and a bottom-inserted discharge pipe is arranged on the reaction kettle. The dripping tank, the reaction kettle, the reflux condenser and the freezing condenser are co
