The technological pro-cess is possessed of advantages of low dust yield, high production capacity of fluidized-bed roasting, etc. 烟尘率低、床能力大等优点,同时存在制粒工艺较为复杂的问题,本文根据生产实践提出了解决办法。
Technical retrofitting of fluidized-bed roaster, froth column corrugated packing and converter, and enhanced roasting and control of oxygen to sulphur ratio are discussed. 重点对强化焙烧和沸腾炉改造、泡沫塔改造、干吸塔波纹填料改造、转化工序氧硫比控制和转化器改造作了论述。
The technical retrofitting measures for pyrite-based sulphuric acid plant are introduced with respects to fluidized-bed roasting, cleaning, drying and absorption and conversion and energy savings. 介绍了硫铁矿制酸装置沸腾焙烧、净化、干吸、转化和节能等方面的技改措施。
