一、概述电除尘技术,就其原理而言,从1908年美国柯特雷尔(Cottrell)博士发明用电除尘技术收捕细小的微粒和液体雾滴后,可以说半个多世纪以来,没有什么变化,理论上也没有什么突破,只是在结构尺寸、材料、附件、电源装置和操作运行方法上有不同程度的改进。武钢500吨大型吹氧平炉应用电除尘始于七十年代末期。由于平炉采用吹氧工艺,在产量大幅度增长的同时,吹氧过程中所产生的褐色烟尘量比不吹氧时大10～15倍,最高可达8克/标米~3,严重地污染了大气。吹氧平炉的烟气具有浓度大、温度高、粒度细
First, an overview of ESP technology, its principle, from the United States in 1908, Dr Cottrell (Cottrell) invented the ESP technology to capture small particles and liquid droplets, it can be said for more than half a century, there is no What changes, in theory, there is no breakthrough, but in the structure size, materials, accessories, power devices and operating methods have varying degrees of improvement. WISCO 500 tons of large oxygen blowing furnace application ESP began in the late seventies. As flat blast furnace oxygen blowing process, a substantial increase in production at the same time, the process of blowing oxygen generated by the amount of brown smoke than do not blow when oxygen is 10 to 15 times the maximum up to 8 g / m 3, serious pollution The atmosphere. Oxygen blowing furnace with a large concentration of flue gas, high temperature, fine particle size
