摘要
结合硫酸生产的特点，充分利用废热的方法，提出一种采用流态化技术，还原回收硫铁矿渣（灰）中铁元素的工艺流程，并时流程中的流态化还原炉进行了初步的物料，热量衡算，同时对该工艺流程技术经济比较作了小结。认为此工艺流程技术可靠，有直接经济效益，对综合利用硫铁矿渣（灰）中的铁元素，消除渣（灰）对环境的污染，有着深远的意义。
In order to utilize the waste heat made in the course of the produc-tion of sulfurlc acid,a new process of fluidization technique using to reduce andreclain Fe from pyrite cinder was put forward.The balance of mass and heat ofthe fluidized reduced furnace in the process was calculated,and the economicreckoning comparison of the technique was summarized.The results showed thatthe technique of the process is feasible,economic benefit is good,and it can uti-lize Fe of pyrite cinder comletely。
