摘　　要：为改善金属冶炼的作业环境,提高烟尘捕集率,设计采用在固定气幕式全密闭罩上加装顶部气幕机构、加料门气幕机构以及出钢门气幕机构的方式对烟尘进行捕集,当电炉工作时,启动气幕机构,捕集罩本体内部的负压氛围不会受到影响,烟尘被封闭在捕集罩本体内部不散逸,实现了电炉整个炼钢过程中烟尘被全面、连续、高效地捕集。结果显示此捕集装置结构紧凑,密闭性强,漏风率低,除尘效果好,显著改善了作业环境。To improve the operation environment of metal smelting and increase the rate of dust catcher,this design uses the method of installing the top air curtain mechanism,the feeding door air curtain institution and the steel door air curtain body on the fixed air curtain fully airtight cover to capture the smoke. When the electric furnace is working,and the air curtain institution is started,the negative pressure atmosphere inside the capture hood body will not be affected; the soot sealed in the capture hood body will not escape,thus to realize the complete,continuous and efficient dust capture during the whole steelmaking process of the electric furnace. The results show that the trap is compact in structure,strong in tightness,low in air leakage rate,good in dust removal efficiency,and the working environment is improved significantly.
