Method and device for realizing quality-divided utilization of alternative fuel of cement kiln and cement kiln
The invention relates to a method and device for achieving quality-divided utilization of alternative fuel of a cement kiln and the cement kiln, the device comprises an alternative fuel feeder, a pyrolyzing furnace, an activating furnace and a gas-solid separation unit, an inlet of the pyrolyzing furnace is connected with a solid particle outlet of the gas-solid separation unit through a pipeline, and the alternative fuel feeder is connected with the pipeline; the alternative fuel and solid particles discharged from the gas-solid separation unit enter the pyrolyzing furnace through an inlet of the pyrolyzing furnace independently or after being mixed, and the alternative fuel is pyrolyzed to obtain first calorific value fuel and semi-coke particles; the activating agent enters the activating furnace through the activating agent inlet, the semicoke particles enter the activating furnace through the fuel inlet and are activated by the activating agent, and gas-solid mixed fuel and ash are obtained; the gas-solid mixed fuel is separated in the gas-solid separation unit to obtain second calorific value fuel and solid particles, the solid particles are discharged through the solid particle outlet and enter the pyrolyzing furnace to provide heat for pyrolysis of the alternative fuel, and the calorific value of the first calorific value fuel is larger than that of the second calorific value fuel.
一种实现水泥窑炉替代燃料分质利用的方法及装置、水泥窑炉，该装置包括：替代燃料进料器、热解炉、活化炉和气固分离单元，热解炉入口与气固分离单元的固体颗粒出口通过管道相连，替代燃料进料器与管道相连，替代燃料和来自气固分离单元排出的固体颗粒各自独立或混合后经热解炉入口进入到热解炉内，替代燃料经热解后得到第一热值燃料和半焦颗粒；活化剂经活化剂入口进入活化炉，半焦颗粒经由燃料入口进入活化炉内被活化剂活化，得到气固混合燃料和灰分；气固混合燃料在气固分离单元内分离得到第二热值燃料和固体颗粒，固体颗粒经固体颗粒出口排出并进入热解炉为替代燃料热解提供热量，其中第一热值燃料的热值大于第二热值燃料的热值。
