隧道窑烟气排放的真实检测及促进达标的措施

Detection of tunnel kiln flue gas emission and related measures

虽然现有的隧道窑具有脱硫除尘设施,大多数也都通过环评和环保验收,但真实工况排放大多数的指标不达标,即现在的脱硫除尘技术方案,不能稳定满足隧道窑实际生产工艺,烧结砖行业缺少真实的排放数据,通过正常生产的真实工况的检测数据的分析,不达标的主要原因是基准空气过量系数太低。为此分析了各种促进达标的技术、工艺措施,烟热分离利用和处理是比较切合实际的技术措施,能促进排放达标。

In this paper,through the analysis of the actual production of the actual test data,the main reason for noncomplianceis the benchmark air excess coefficient is too low,not suitable for the actual tunnel kiln technology,anal?ysis of various standards to promote the technical,technological measures,and processing is more practical technicalmeasures to promote emission to reach the standard.
