Impeller and distributor

The impeller comprises a plate body and a plurality of blades, the plate body is provided with a plurality of flow dividing holes distributed in the circumferential direction in a radial mode, the blades correspond to the flow dividing holes, the blades and the plate body are integrally formed, and the blades are obliquely arranged in the direction away from the flow dividing holes from the plate body in the axial direction of the impeller. And the projection width of the blades to the plate body is greater than or equal to that of the shunting holes, so that gas and liquid are prevented from flowing into pores of the blades and the shunting holes to realize uniform shunting. 本实用新型提供一种叶轮及分配器，该叶轮包括板体与多个叶片，其中，板体上设有呈辐射状的周向分布的多个分流孔，多个叶片对应于每个分流孔，叶片与板体一体成型设置，沿叶轮的轴向，叶片自板体朝向背离分流孔的方向倾斜设置，且叶片投影到板体的宽度大于等于分流孔的宽度，避免气液流入叶片与分流孔的孔隙中，以均匀分流。
