顶装焦炉加煤除尘工艺存在的问题及改进

摘要

针对顶装焦炉加煤除尘系统运行中存在的问题，将除尘干管和水槽改为箱式复合体结构，并将水封式防爆装置改为油式防爆装置，改进后提高了加煤除尘系统运行效果，降低了运行费用。%Regarding to the problems existing in the charging emission control system of top-charging coke oven,the de-dusting main and water tank are modified to compound box structure,and water seal type explosion proof device is replaced by oil type explosion proof device. The charging emission con-trol effect is improved and running cost is reduced after improvement.
