The present invention is to prevent stagnation, adhesion, or growth of a powdery polymer below a gas dispersing plate of a gaseous phase polymerizer, and therefore can prevent thr choking of the gas dispersing plate with the powdery polymer. An inclined member is provided below the gas dispersing plate of the polymerizer for distributing the flow of the gaseous phase toward the gas dispersing plate along the inner wall surface of the polymerizer. The inclined member having an inclined upper surface.
Cette invention concerne un dispositif pour empêcher la stagnation, l'adhérence ou la croissance d'un polymère en poudre sous la plaque de distribution de gaz d'un appareil de polymérisation en phase gazeuse et, par suite, l'obturation de la plaque par le polymère. Un élément incliné, présentant une surface supérieure inclinée, est placé sous la plaque de distribution de gaz de manière à diriger le flux de gaz vers la plaque de distribution en suivant la paroi interne de l'appareil.
