Abstract

Corona discharge low-temperature plasma technology has good performance in treating dust and removing gaseous pollutants. In this paper, the dust and SO₂ in the flue gas are removed by using the ground electrode atomization negative corona discharge device under the action of a magnetic field, and the discharge characteristics of the device, the removal efficiency of dust and sulfur dioxide, and its influencing factors are studied. The results show that the discharge characteristics and dust removal and desulfurization efficiency of the ground electrode atomization negative corona discharge under the action of a magnetic field are superior to the traditional l corona discharge and are almost affected by the extension of the operating time. Finally, the ground electrode atomization negative corona discharge under the action of a magnetic field is analyzed. The dust removal and desulfurization mechanism of corona discharge provide a reference for the development of dust removal and integrated desulfurization equipment.

磁场影响下接地电极雾化对负电晕放电除尘脱硫的影响研究

电晕放电低温等离子体技术在处理粉尘和去除气体污染物方面具有良好的性能。本文采用地电极雾化负电晕放电装置在磁场作用下去除烟气中的粉尘和二氧化硫，并对该装置的放电特性、粉尘和二氧化硫的去除效率及其影响因素进行了研究。结果表明:磁场作用下地电极雾化负电晕放电的放电特性和除尘脱硫效率优于传统的负电晕放电，且几乎不受工作时间延长的影响。最后，对磁场作用下的地电极雾化负电晕放电进行了分析。电晕放电的除尘脱硫机理为除尘综合脱硫设备的开发提供了参考。
