摘　　要：当前,转炉除尘装置一般设定为单向结构,排放控制的覆盖范围较小,导致粉尘浓度差值增加。本研究设计一种新的炼钢厂转炉除尘装置超低排放控制方法,然后对该方法进行测试。根据排放控制需求,确定初始排放控制范围,设计交叉超低排放控制结构。采用多层级的方式,扩大排放控制的覆盖范围,构建多阶除尘装置超低排放控制模型,通过关联图谱处理实现排放控制。最终测试结果表明,该方法具有实际应用价值,粉尘浓度差值被控制在5.2 mg/m~3以下。Currently,the converter dust removal device is generally set to a unidirectional structure,with a small coverage of emission control,resulting in an increase in dust concentration difference.This study designs a new ultralow emission control method for converter dust removal devices in steelmaking plants,and then tests this method.Based on emission control requirements,determine the initial emission control range,and design a cross ultra-low emission control structure.Adopt a multi-level approach to expand the coverage of emission control,construct an ultra-low emission control model of multi-level dust removal device,and achieve emission control through correlation graph processing.The final test results indicate that this method has practical application value,and the dust concentration difference is controlled below 5.2 mg/m~3.
