DISTRIBUTOR PLATE FOR POLYMERIZATION APPARATUS

摘要

PURPOSE: A distributing plate for a vapor-phase polymerizing apparatus is provided to prevent the clogging phenomenon of a specific region in the distributing plate positioned at the inlet of reactive products and to increase the polymerization of the reactive products by uniformly distributing the reactive products. CONSTITUTION: A distributing plate(20) for a vapor-phase polymerizing apparatus(1) generates propylene by implementing vapor-phase polymerization with a solid-phase polymerizing catalyst. The distributing plate is polygonal cone-shaped or convex shaped. Vapor from the vapor-phase circulating system of a reactor is uniformly dispersed in the polymerizing apparatus by the distributing plate. A plurality of groups of spraying holes is distributed, and the sizes of the spraying holes are different.
