一、前言 宝钢烧结厂450m~2烧结机主排气净化,采用ESCS-ST600静电除尘器,这是一种七十年代发展起来的新型静电除尘器。据有关资料介绍,这种静电除尘器能有效捕集大于0.01μ级的超细粉尘,粉尘比电阻适应范围为10～10~(14)欧姆·厘米,效率可达99％以上。 现代化烧结生产都是向大型化、高碱度方向发展,这给烧结机主排气的净化带来了新的问题:排气量大,含尘浓度较低,而粉尘比电阻值极高,一般在10~(13)欧姆·厘米以上。要净化这种废气,采用普通的电除尘器
I. Introduction Baosteel Sintering Plant 450m ~ 2 sintering machine main exhaust purification, the use of ESCS-ST600 electrostatic precipitator, which is a seventies developed a new type of electrostatic precipitator. According to relevant information, this electrostatic precipitator can effectively trap ultrafine dust greater than 0.01μ, and the specific resistance of dust is 10 ~ 10 ~ (14) ohm · cm, and the efficiency can reach over 99%. The modernization of sintering production are to large-scale, high alkalinity direction, which gives the sintering machine main exhaust purification has brought new problems: large displacement, lower dust concentration, and dust than the high resistance, Generally 10 ~ (13) ohm · cm above. To purify this exhaust, the use of ordinary electrostatic precipitator
