Description

TECHNICAL FIELD

[0002] The heating method of the polypropylene reactor is usually selected according to the characteristics of the polypropylene production process and the reactor design. The production of polypropylene generally involves a polymerization reaction.

[0003] The existing patent with the publication number CN221889849U proposes a reactor for polypropylene. The device sets a rotating mechanism inside the reaction cylinder on the reactor of polypropylene. When the rotating drive on the rotating mechanism is started, the several spiral rotating plates on the rotating mechanism rotate along the inner wall of the reaction cylinder, thereby driving the gas generated by the liquid-phase raw materials input at the bottom of the reaction cylinder to flow upward. The uniform input catalyst sprayed by the arc-shaped structure spray box at the top collides with the upward flowing gas, so that the reaction gas and the catalyst input at the top stay in the reaction cylinder for a long time and fully polymerize in the reaction cylinder, thereby improving the polymerization efficiency of polypropylene in the reactor.

[0004] However, when the device heats and reacts polypropylene, the polypropylene may solidify into lumps. If the lumps directly fall and block the discharge pipe, it will cause the blockage of the discharge pipe in the later period. UTILITY MODEL CONTENT
