The invention discloses a gasification nozzle. The gasification nozzle comprises a conveying portion for conveying a material, and an injection portion connected to the tail end of the conveying portion and used for injecting the material, wherein the conveying portion comprises a conveying main pipe and a plurality of conveying branch pipes connected with the conveying main pipe through a diverter. The diverter comprises a substrate, the conveying main pipe is connected to the top surface of the substrate, all the conveying branch pipes are connected to the bottom surface of the substrate, and the substrate is provided with a plurality of through holes making the conveying main pipe connected with all the conveying branch pipes; the diverter also comprises a polyhedral cone with the cone base connected to the top surface of the substrate and the cone top positioned in the conveying main pipe, all side surfaces of the polyhedral cone and parts of the sidewall of the conveying total main respectively form a guiding surface of all the through holes, and the side surfaces of the polyhedral cone cover the top surface of the substrate. The invention also discloses a gasifier comprising the gasification nozzle. The material is uniformly diverted in the gasification nozzle to prevent powder accumulation and obstruction of the material in order to improve the production efficiency of a gasification furnace.
Description
technical field [0001] The invention relates to the field of coal chemical industry, in particular to a gasification nozzle and a gasifier. Background technique [0002] Coal gasification technology is the basis for the development of coal-based chemicals, liquid fuels, IGCC power generation, hydrogen production and other processes, and is a leading technology in the coal chemical industry. Due to the rapid development of industries such as synthetic ammonia, methanol, dimethyl ether, coal-to-oil, and coal-to-olefins, China's coal gasification process is rapidly transitioning from the old-fashioned UGI furnace lump coal intermittent gasification to the advanced pulverized coal gasification process. There is a strong demand for various types of pulverized coal gasification technology and equipment. [0003] The gasification reaction is carried out under high temperature and pressure conditions. Among them, the gasification nozzle is used to make the materials such as coal p...
