摘要
焦化行业及其相关产业是乌海市重要的经济组成部分。炼焦化学工业的生产活动中,煤炭的输送、粉碎、配合、及焦炭的筛分是粉尘排放的主要原因;炭化室正压操作致使荒煤气从炉门、装煤等处逸出;在出焦装煤操作中,污染物排放较难控制;工艺尾气含有氧、硫化氢、酚、苯并[a]芘等危害性大的污染物,点多面广,成分复杂;是炼焦化学工业大气污染物排放的特点,做好焦化行业环境保护验收检测工作,对于确保焦化行业提标改造,促进该行业健康发展及相关产业链发展具有十分重要的意义。
The coking industry and relevant industries are the main economic activities in Wuhai city.During coking chemical producting,the coal transportation,crushing,coordination and the coke screening are the main factors leading to the dust emission.The carbonization chamber positive pressure operation causes the leakage of the raw coke oven gas from the fire door or the coal loadings.In the procedure of producting the coke coal,the pollutant emission pumps to the atmosphere environment with the higher rate.Along with the recovery of tail gas containing ammonia,hydrogen sulfide production process,phenol,benzo[a]pyrene and other hazards of pollutants of the large.In addition to a wide range of complex composition is characteristic of coking chemical industry emissions of atmospheric pollutants.Therefore,do a good job in the coking industry,environmental protection acceptance monitoring work,to comprehensively promote coking industry upgrading and reconstruction,has the very vital significance to promote the healthy development of the industry chain development and related industries.
