针对干熄焦焦罐在熄焦车轨道上如何加盖及应加装什么设施的问题，介绍了中冶焦耐的技术解决方案。方案中新结构焦罐加揭盖装置及其操作方法可实现焦罐在熄焦车轨道运输过程中加上焦罐盖。解决了焦罐运输过程中红焦在焦罐中与空气中的氧气直接燃烧、产生大量二氧化碳排放到空气中的问题，并减少了炼焦损耗。避免了因焦炭在焦罐中燃烧破坏罐口处衬板，导致干熄焦维修成本增加的问题。

This paper introduces ACRE’s solution to the covering-uncovering device for coke bucket,which could realize covering the coke bucket lid during the bucket car traveling along the rails.This solution stops the red coke in bucket from burning in air during traveling,prevents from generating large amount of CO2 into the atmosphere,minimizes coke burning loss and avoids additional cost for CDQ maintenance due to damaged liner plate at bucket mouth caused by coke burning.
