The invention relates to a method for removing gas phase hydrogen chloride from dichloropropanol to produce epichlorohydrin. The method comprises the steps of: 1. filling a tubular reactor or a fixed bed reactor or a fluidized bed reactor with an atom mixed alkaline catalyst; 2. sending dichloropropanol produced by glycerol chlorination in last process into the tubular reactor or the fixed bed reactor or the fluidized bed reactor to undergo reaction; 3. directly removing the gas phase hydrogen chloride generated in step 2 reaction to obtain crude epichlorohydrin; 4. performing purification treatment on the gas phase hydrogen chloride removed in step 3, then conducting compression to a pressure of more than 0.2MPaG and subjecting the compressed hydrogen chloride to cyclic utilization in the procedure of production of dichloropropanol by the last process of glycerol chlorination.
