Sludge blending combustion system based on circulating fluidized bed boiler

The invention discloses a sludge blending combustion system based on a circulating fluidized bed boiler. The sludge blending combustion system comprises a sludge receiving and conveying system, a quick lime and limestone receiving and conveying system, a material mixing, drying and crushing system, a semi-dried material conveying system and a dried material receiving and conveying system, the sludge receiving and conveying system and the quick lime and limestone receiving and conveying system are communicated with an inlet of the material mixing, drying and crushing system, and an outlet of the material mixing, drying and crushing system is communicated with the semi-dried material conveying system and the dried material receiving and conveying system. The system can reduce the sludge treatment cost, and is small in occupied area, small in investment amount and high in economic benefit. 本发明公开了一种基于循环流化床锅炉的污泥掺烧系统，包括污泥接收及输送系统、生石灰及石灰石接收及输送系统、物料混合干燥粉碎系统、半干化物料输送系统及干化物料接收及输送系统；污泥接收及输送系统及生石灰及石灰石接收及输送系统与物料混合干燥粉碎系统的入口相
