摘　　要：为了解决磷酸浓缩装置氟吸收系统被硅胶堵塞问题,在磷酸浓缩装置氟吸收系统中引入氟化铵溶液。实验表明,加入氟化铵溶液带入的F为氟吸收系统中氟总量的5%左右,能有效溶解系统中的硅胶,确保循环系统吸收液的品质,使系统正常运行。To solve silica gel blocking problems in the fluorine absorption system of wet phosphoric acid plant, ammonium fluoride is introduced into the fluorine absorption system. The results show that, the addition of ammonium fluoride solution can effectively dissolve the silica gel, thus ensure the quality of absorption solution in the circulation system,which makes the fluorine absorption system run well.
