The utility model relates to a system for strengthening propylene polymerization. The system comprises a polymerization reactor, a gas-phase feeding unit, a liquid-phase feeding unit, a polymerizationmolecular weight adjusting unit, a backflow unit, a cooling unit and a micro-interface generator. Propylene is crushed to form micron-scale micron-sized bubbles, and the micron-sized bubbles are mixed with a solvent to form a gas-liquid emulsion, so that the phase boundary area of gas and liquid phases is increased, the synthesis efficiency of polypropylene is improved, the reaction efficiency ofpropylene is improved, and the cost is saved; through the first heat exchanger, the second heat exchanger and the third heat exchanger, raw materials and generated materials are subjected to heat exchange, energy is saved, through combined use of the first micro-interface generator and the second micro-interface generator, the residence time of micron-sized bubbles in a reaction area is prolonged, gas and liquid phases ar
