摘要
济钢机械设备制造厂5t电炉除尘器,由于设备本体变形、自身设计缺陷及过程累积误差等原因,造成回转臂经常折断、滤袋"硬壳化"、介质捕集率低等。采用极坐标位控清灰机构,通过PLC控制技术控制喷嘴摆动和径向位移,实现喷嘴的反吹定位,达到调整清灰时间或风量,控制反吹顺序,适应工况变化,清除滤袋表面集灰目的。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。
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 hardshelled and low dust arrestment rate etc. Polar coordinate mechanism is adopted. Then the spray nozzle swing and radial displacements are controlled by PLC controll technique, the spray nozzle's reverse blow spotting is realized and the purposes to adjust deashing time or blowing rate, control reverse blow sequence, adapt working condition, clean the surface dust of bag are achieved. The use of the polar coordinate mechanism shows that the intrinsic malfunctions are eliminated out and out, the dust arrestment rate is improved up to more than 95% and the fixed cost is reduced by 100,000 Yuan.
