生产直接还原铁的粉尘治理研究

Dust mitigation during production of direct reduced iron

生产直接还原铁工艺的主要污染物是粉尘 ,而且粉尘的产生量大、粒度较细、成分复杂、处理难度相当大。本文简要介绍了该工艺的粉尘污染现状和原有的粉尘处理系统存在的问题 ,结合粉尘的性质和除尘装置的性能要求 ,对除尘装置进行了选择。

Main polutant occurred during production of direct reduced iron is dust of great amount,fine particle and complicated composition.Based on analysis of dust pollution conditions and problems existed in present dust-removal facilities and according to dust's properties and requirement on performance of dust-removal facilities,some suggestions to selection of dust-removal facilities are made.
