The invention discloses a coal water slurry atomizing nozzle and a gasification furnace with the same. The coal water slurry atomizing nozzle comprises a fuel gas pipe, a first gasifying agent pipe, a coal water slurry pipe, a coal water slurry cyclone, a second gasifying agent pipe and a gasifying agent cyclone, wherein the coal water slurry pipe sleeves the first gasifying agent pipe, a coal water slurry channel is formed between the coal water slurry pipe and the first gasifying agent pipe, and the lower end opening of the coal water slurry channel is a coal water slurry outlet; the coal water slurry cyclone is arranged inside the coal water slurry channel and is adjacent to the coal water slurry outlet; the second gasifying agent pipe sleeves the coal water slurry pipe, a second gasifying agent channel is formed between the second gasifying agent pipe and the coal water slurry pipe, and the lower end opening of the second gasifying agent channel is a second gasifying agent outlet; and the gasifying agent cyclone is arranged in the second gasifying agent channel and is adjacent to the second gasifying agent outlet. The coal water slurry atomizing nozzle disclosed by an embodiment of the invention has the advantages of simple structure, good mixing effect and the like.
Description
technical field [0001] The invention relates to a coal-water slurry atomizing nozzle, and also relates to a gasifier with the coal-water slurry atomizing nozzle. Background technique [0002] Using coal gasification technology to convert coal into synthesis gas is an effective way to utilize coal efficiently and cleanly. Gasifier is the core unit of coal gasification technology. The coal water slurry atomizing nozzle of the existing gasifier cannot mix the coal water slurry and the gasification agent well. Contents of the invention [0003] This application is based on the inventor's discovery and recognition of the following facts and problems: [0004] The coal water slurry atomizing nozzle of the gasifier determines the mixing of coal water slurry and gasification agent. The existing coal-water slurry atomizing nozzles used in gasifiers spray out coal-water slurry and gasification agent in the form of coaxial jets, resulting in poor mixing of coal-water slurry and ga...
