High-proportion alternative fuel pretreatment cement kiln incineration system and method
The invention relates to the technical field of alternative fuels in the cement industry, and discloses a high-proportion alternative fuel pretreatment cement kiln incineration system which comprises a stacking shed, a storage system, a rotary kiln, a pulverized coal burner, a cooling machine, a tertiary air pipe and a preheating raw material preheater. The device further comprises a crushing system, a homogenizing system, a metering system, a conveying system, a gravity type feeding system, a multifunctional decomposing furnace, a special alternative fuel combustor and an air conveying system. The crushing granularity of the alternative fuel is controlled according to the flue gas suspension speed, so that the alternative fuel is subjected to suspension combustion in the multifunctional decomposing furnace and is metered through the three metering systems, one path of the alternative fuel is fed into the special combustor, and the special combustor and the pulverized coal combustor are arranged up and down in the rotary kiln; pulverized coal combustion is used for driving alternative fuel combustion; the feeding of alternative fuel is realized by adopting a gravity type feeding system and an air locking blanking valve with two change-over switches, and the air leakage rate in the feeding process is reduced.
本发明涉及水泥工业替代燃料技术领域，且公开了一种高比例替代燃料预处理水泥窑焚烧系统，包含堆棚、储存系统、回转窑、煤粉燃烧器、冷却机、三次风管、预热生料预热器，还包括粉碎系统、均化系统、计量系统、输送系统、重力式喂料系统、多功能分解炉、替代燃料专用燃烧器、风力输送系统。本发明根据烟气悬浮速度来控制替代燃料的破碎粒度，使得替代燃料在多功能分解炉实现悬浮燃烧，且通过三道计量系统计量，替代燃料一路喂入专用燃烧器，专用燃烧器与煤粉燃烧器在回转窑内呈现上下布置，用煤粉燃烧带动替代燃料燃烧；采用重力式喂料系统与两道切换开关的锁风下料阀实现替代燃料的喂入，减少喂料过程中的漏风量。
