唐钢转炉二次除尘改造

介绍了唐钢第二钢轧厂为达到国家环保部对19个省47个地级市提出的特别排放限值,对转炉二次除尘系统实施的改造。改造中,摒弃了通常采用的增加过滤面积降低过滤风速的方法,而是将核心的滤料更换为高效低阻力的戈尔覆膜滤料。改造后的粉尘的排放量控制在特别排放限值以下,风机系统能耗也大大降低,为同类型设备改造提供了参考。

REFORMATION OF SECONDARY DUST REMOVING SYSTEM OF CONVERTER IN TANG STEEL

To reach the special pollution limit given by Ministry of Environmental Protection of the People’s Republic of China,the reformation of converter secondary dust removing system is carried out in No. 2 Steel Rolling Mill of Tang Steel. In reformation,the normal method to increase filtering area and reducing wind speed is give off,whereas the new method is adopted： to replace the core filter material with high- coefficient and low- resistance filter material,Gore film. After reformation,the dust discharge amount is controlled under the special limit value,and the energy consumption of blower system greatly reduced. That offers a reference for other equipments of same type.
