Pulverized coal injection distributor

The invention discloses a pulverized coal injection distributor. The distributor is composed of a connecting flange, an injection main tube, a cone body, ceramic tubes, injection branch tubes, a high-speed steel gasket, an end cover and a fixing bolt, and surfacing of tungsten carbide is conducted on the pressure-bearing easy-to-damage surface of the end cover; and injection is conducted inside the cone body on the ceramic tubes inlaid in the inner walls of the injection branch tubes, and inner diameters of the ceramic tubes are consistent with inner diameters of externally-connected branch tubes, so that the phenomenon that abrasion on the inner wall is caused is due to the fact eddy occurs in the conveying process of pulverized coal is prevented. A thick-wall tube with the inner diameterof 92 mm and the thickness of 8 mm is selected as the injection main tube. The interior of the cone body comprises 28 injection branch tubes. The novel pulverized coal injection distributor has the advantages that wear resis
