Entrained-flow bed coal gasification black water flash wear-resistant three-way pipe

The utility model relates to a coal gasification entrained-flow bed accessory. According to the scheme, the entrained-flow bed coal gasification black water flash evaporation abrasion-resistant three-way pipe comprises a three-way pipe body, an upper end opening of a vertical section of the body is an inlet, a lower end opening of the vertical section of the body is a closed buffer section, and anend opening of a horizontal section of the body is an outlet. And the length of the buffer section is not less than the inner diameter of the pipe. The buffer has the advantages that the structure issimple, and only the length of the buffer section needs to be modified; 2, the wear-resistant layer is sprayed on the inner wall, so that the wear resistance of the inner wall is greatly enhanced; the number of airflow vortexes formed in the intersecting area of the abrasion-resistant three-way pipe is small, the flow speed of the airflow vortexes is low, abrasion to the inner wall of the pipe issmall, leakage caused by a
