电除尘器操作方式有微负压和负压两种。平炉吹氧量为6000标米~3/时,每炉钢吹氧时产生的粉尘量为15.5吨,需要除尘量为11.4吨。在两台苏式KY-100型余热锅炉增设了9排27支吹灰器,使出口烟温<250℃,满足了电除尘器对温度的要求。 10号平炉60米~2电除尘器是一台工业性试验设备。目前除尘效率为95.8％,日收尘量为42吨,回收一吨粉尘用电183度,作业率为98.04％,与平炉配合率为86.23％。最近投产的12号平炉78米~2电除尘器获得满意的效果。
Electrostatic precipitator mode of operation are negative and negative pressure two. Open-hearth oxygen blowing 6000 mark ~ 3 / hour, each blast furnace steel blowing oxygen produced 15.5 tons of dust, the amount of dust required for the 11.4 tons. An additional 9 rows of 27 soot blowers were added to two Soviet-type KY-100 waste heat boilers to make the exit temperature <250 ° C, meeting the temperature requirements of the electrostatic precipitator. 10 Flat furnace 60 m ~ 2 ESP is an industrial test equipment. At present, the dust removal efficiency is 95.8%, the daily dust collection capacity is 42 tons, the electricity consumption for recycling one ton of dust is 183 degrees, the operating rate is 98.04% and the matching rate with open hearth is 86.23%. Recently put into operation on the 12th open hearth 78 m ~ 2 ESP to obtain satisfactory results.
