The invention discloses a tubular reactor for generating choline chloride by utilizing exhaust gas of chlormequat chloride production. The tubular reactor comprises a reaction tube and a jacketed pipe, wherein the jacketed pipe is sleeved on the periphery of the reaction tube. The invention also discloses a method for generating choline chloride by utilizing exhaust gas of chlormequat chloride production. The method comprises the following steps: (1) introducing exhaust gas of chlormequat chloride production into water containing choline chloride, thereby forming a methylamine water solution;(2) fully mixing chlorohydrin with methylamine water solution, thereby forming a mixed solution; (3) introducing the mixed solution into the tubular reactor, adjusting the flow of mixed solution and the pressure of tubular reactor, introducing hot water into the jacketed pipe, controlling the temperature of the reaction tube, fully reacting and then collecting choline chloride aqueous solution; (4) dewatering the choline
