摘　　要：随着炼铁厂环保技术不断发展,高炉炉顶均压煤气经过回收后,每年可减少均压煤气放散量约70%,同时减少碳排放量约70%,故1989年发布的《炼铁厂卫生防护距离标准》(GB1160-89)已不能满足目前相关法规政策要求,因此探究进步条件下炼铁厂卫生防护距离的合理性显得尤为重要。根据对某钢铁厂30 d的逐时CO监测数据表明,距离高炉中心下风向600m的监测点出现超标现象。因此,在确定炼铁厂卫生防护距离时,需要结合当地气象条件和企业污染防治措施,采取不同的卫生防护距离。With the continuous development of iron factories,the recovery of blast furnace top pressure equalization gas can reduce the emission of equalization gas by about 70% and reduce carbon emissions by about 70%.Therefore,the Health Protection Zone Standard for Ironmaking Plants(GB1160-89)issued in 1989 can no longer meet the current requirements of relevant laws and policies.Therefore,it is particularly important to explore the rationality of health protection distances under present pollution control measures.According to the 30-day hourly CO monitoring data of a steel plant,the monitoring point 600m from the downwind direction of the blast furnace center has exceeded the standard.Therefore,it is reasonable to determinate health protection distance according to the local meteorological condition and pollution control measures.
