不锈钢纤维滤袋式电除尘器的实验研究

Experimental Investigation of Sack Electrostatic Precipitator Made of Fibrous Stainless Steel

对一种新型的不锈钢纤维滤袋式电除尘器(简称袋式电除尘器)进行了理论分析和实验研究。研究结果表明,该滤袋式电除尘器比管式电除尘器和现在使用的袋式除尘器都具有更高的除尘效率,而且对细微粉尘具有更强的捕集能力。从效率与过滤风速、电场电压及粉尘浓度的关系曲线中,也显示出这些基本参数对滤袋式电除尘器除尘效率的影响规律。因此,可广泛应用于炼钢电炉和工业炉窑的除尘设备。作者的工作有助于研究电除尘器,对设计高效率和寿命长的电除尘装置具有指导作用。

A theoretical and experimental investigation on a new type of sack electrostatic precipitator (SEP) made of fibrous stainless steel is presented. The experimental results show that the SEP is more efficient than a tubular EP and other existing sack precipitators. It draws a conclusion that SEP is better in collecting slight particles than tubular EP and sack precipitators. The curves of efficiency versus filtering velocity, voltage and dust consistency indicate how these primary parameters influence the efficiency of the SEP. Therefore, the SEP may be used as a extensively dust trap for steel making electric furnaces and some other industrial ones. The work is helpful to research electrostatic precipitator and design efficient and endurable electrostatic precipitator equipments.
