摘　　要：对焦化厂煤气净化初冷器喷洒系统进行了改造,每台初冷器冷凝液循环喷洒回液管增加“旋流离心式分离器”,在离心力作用下,加速了氨水、轻质焦油、富含煤焦粉的团聚物3种组分的有效分离;同时采用高效喷洒管和加强初冷器下段补焦油质量等措施,大大改善了初冷器使用效果,取得了良好的经济效益。This paper expounds a modification of spraying system of primary cooler in gas treatment plant,i.e.a“Swirl centrifugal separator”was added to the recycling spray return pipe of condensate of each primary cooler.Under the action of centrifugal force,the effective separation of the three components of ammonia,light tar and coal-tar-rich agglomerate was accelerated,and high-efficiency spraying pipe and the tar quality of the lower part of primary cooler were enhanced and the performance of the primary cooler is greatly improved with remarkable econo mic benefits.
