dust control

The importance and difficulty of iron outlet flue dust collecting technology of blast furnace were introduced,and the characteristics of iron outlet flue dust collecting technology of three main large-size blast furnaces were analyzed and compared,and trends were predicted.

介绍了高炉出铁口烟尘捕集的重要性和困难性,分析和比较了三种主要大型高炉出铁口烟尘捕集方式的特点,指出了其发展趋势。

The bag filter of the 5t electric furnace at Jigang Mechanical Equipment Manufacturing Factory has never operated smoothly before for the body deformation, designing default and cumulative error of the filter, which cause various of malfunctions including rotating arm breaking,bags hardshelled and low dust arrestment rate etc.

使用证明,极坐标清灰机构彻底消除了原有设备故障,烟尘捕集率提高到95%以上,年可节约费用达10万元。

By using minute particles of SiO2 as dust,simulation research on the EAF dust collection characteristics by cold model coke bed filter was carried out: For fixed bed filter,it was found that the longitudinal distribution of static hold up at steady state can be regarded as constant for a certain gas flow rate condition.

以超细二氧化硅微粒为模拟粉尘,研究了在冷态焦炭过滤床条件下的电炉粉尘捕集特性:即在固定床的实验条件下,当气流速度一定时,平衡状态下静态捕集量在过滤床纵轴方向上的分布状态变化较小;当焦炭颗粒以一定速度下移时,随粉尘供给速率的增大,整体的静态捕集量也随之增加,从上部到下部静态捕集量呈渐增趋势。
