Abstract：Withtheimplementationofthenationalultra-cleanemissionrequirementsbymajordomesticsteelenterprises，the ultra-cleanemissiontransformationofsteelenterprises hasbeenunderwayforfiveyears，and moststeelenterprises have completed theultra-clean emision transformation.However，thetechnologiesand process routes forultra-cleanemission transformatiovary，leading todiffrenteffects.Toughtheastoperatioresultsofconverterdustremovalemissionsnsteel enterprises，itcanbeconcludedthatamong variousconverterdustremovaltechnologiesand processroutes，not everyprocess meets therequirementsofultra-cleanemissions forconverterdustremoval.Therefore，basedonthecurentdrydustremoval technologyandprocessforconverters，thispaperdiscussesandstudiesthefulldrydustremovaltechnologyandprocessroute forconverters，andexplores theimplementationandapplicationofnewtechnologiesand processes inaspetssuchasultra clean emisions，energyconservationandemissonreduction，andreductionofresource waste.The fulldrydustremoval ultra-clean emission technology will have more advantagesand is worthyof research and promotion.

目前我国转炉干法一次除尘技术及工艺路线众多，主要有湿法、半干法和干法三种除尘工艺，烟囱出口颗粒物排放浓度要稳定低于 10mg/Nm3 需经过煤冷前置、放散侧嵌入精除尘等工艺调整，且高温烟气经过喷淋从 800～1000∘C 降至低温无节能工艺，热能损失较大，回收煤气因含水或水蒸气量大，而热值降低。（剩余6807字）
