高炉出铁场电收尘器研制及在武钢5号高炉(即新3号高炉)的应用科技成果,在湖北省科委的主持下,于1993年4月3日通过技术鉴定。武钢5号高炉(3200m~3)出铁场除尘系统采用了A、B二台224m~2电收尘器,每台设计处理烟气量68万m~3/h,设计排放浓度100mg/m~3。该电收尘器于1991年10月19日投入生产,至今已正常运行一年半,经测定,烟尘排放浓度倪为18～28mg/m~3,除尘效率达96.69%～98.3%。通常认为,高炉出铁场烟尘比电阻偏高,不宜采用电收尘器,所以国内大型高炉出铁场除尘一般采用袋式除尘器,国外也仅
Blast furnace tundish electric dust collector and the development of WISCO No.5 blast furnace (ie No.3 blast furnace) application of scientific and technological achievements, under the auspices of the Hubei Provincial Science and Technology Commission, on April 3, 1993 passed the technical appraisal. WISCO No.5 Blast Furnace (3200m ~ 3) used the iron dusting system of A and B with two 224m ~ 2 electric dust collectors. Each designed flue gas volume was 680,000m3 / h, and the designed discharge concentration was 100mg / m ~ 3. The electric precipitator was put into production on October 19, 1991 and has been operating normally for a year and a half. It has been determined that the concentration of dust emission is 18 ~ 28mg / m ~ 3 and the dust removal efficiency reaches 96.69% ~ 98.3%. It is generally believed that blast furnace tundish soot ratio resistance is high, should not be used electric dust collector, so the domestic large-scale blast furnace dump generally use bag filter, foreign only
