摘要
介绍了双益磷化有限责任公司2万t/a硫酸铝装置工艺流程及主要设备选型情况,针对铝土矿品位降低导致反应工序负荷过大、沉降洗涤工序生产能力不足的问题,进行设备改造,实现了装置产能达标;介绍了废水回用措施及效果,颗粒铝和粉状铝联合生产装置及效果;同时提高了成品粉碎工序的机械化水平,降低了产品成本。
To introduce the 20,000 t/a of aluminum sulfate device process flow and main equipments selection in Shuangyi Phosphorus Chemical Industry Co. , Ltd. In the light of the larger reaction process load caused by the lower grade of hauxite the lower washing process production capacity, through improving the devices, to make the devices and capacity reach standards. To introduce the wastewater reuse measures and effect, the devices combined by the particles of aluminum production device and the powdered aluminum production device and the effects. At the same time, to improve the level of mechanization of the finished crushed process,and reduce product cost.
