description The invention discloses an amination system of PP-ST-DVB (polypropylene-styrene-divinylbenzene) based strong-alkali ion exchange fibers. The amination system comprises a horizontal high-pressure reaction kettle and a cylindrical reaction kettle, wet PP-ST-DVB fibers are placed in the horizontal high-pressure reaction kettle, an aqueous solution obtained through dissolving of trimethylamine hydrochloride and NaOH solids has a neutral reaction in the cylindrical reaction kettle, and trimethylamine gas is released; the trimethylamine gas enters the horizontal high-pressure reaction kettle through a gas inlet and is subjected to rapid amination under the high-pressure heating condition; after the reaction is finished, trimethylamine on the surfaces of the fibers is volatilized as far as possible under the conditions of heating, pressure reduction and high-speed rotation of a cylinder in the horizontal high-pressure reaction kettle, most trimethylamine gas is continuously used after condensation recovery, and a sm
