红磷分公司半水-二水磷酸装置氟吸收系统运行不正常,尾气不能达标排放。介绍该装置含氟气体的洗涤工艺,氟洗涤吸收系统存在的设备、材质、堵塞等问题及改造方案。改造后,氟吸收率提高,尾气中氟含量由10～13 mg/m3下降到7～8 mg/m3,确保达标排放。 Red phosphorus branch semi-water - two phosphoric acid plant fluorine absorption system is not functioning properly, the exhaust can not meet the standards. Describes the device containing fluorine gas washing process, fluorine washing absorption system exists equipment, materials, plugging and other issues and transformation programs. After the transformation, the fluorine absorption rate will increase, and the fluorine content in tail gas will be reduced from 10 to 13 mg / m3 to 7 to 8 mg / m3 to ensure the discharge standard.
