摘　　要：为了实现铜冶炼高温烟气粉尘的高效脱除,本文分析高温烟气领域除尘技术研究现状,搭建了基于铜冶炼烟气工况的高温电除尘中试装置,分析了炼铜粉尘的形貌、粒径等特性,研究了不同烟气流速、电压对除尘效率的影响,得出电除尘关键参数最佳设置方法。结果表明,高温电除尘器烟气流速为0.48 m/s时,烟气颗粒既不会造成高温电除尘器严重积灰,也不会导致大量颗粒大量逃逸,除尘效率最佳;电场电压越高,出口粉尘浓度越低,除尘效率越高,实践中要在满足除尘效率的前提下寻找能耗最低的电压值。在福建某铜冶炼厂进行高温电除尘技术工程应用试验,测试结果表明,高温电除尘器出口烟气含尘浓度由2.19 g/m^(3)降至62 mg/m^(3),除尘效率大于97.1%。In order to achieve efficient dust removal from copper smelting high-temperature flue gas,this paper analyzed the current research status of dust removal technology in the field of high-temperature flue gas,built a pilot plant for high-temperature electrostatic precipitator based on the operating conditions of copper smelting flue gas,analyzed the morphology,particle size,and other characteristics of copper smelting dust,studied the impact of different flue gas flow rates and voltages on dust removal efficiency,and obtained the optimal setting method for key parameters of electrostatic precipitator.The results show that when the flue gas flow rate of the high-temperature electrostatic precipitator is 0.48m/s,the flue gas particles will not cause serious dust accumulation in the high-temperature electrostatic precipitator,nor will cause a large number of particles to escape,and the dust removal efficiency is the best;The higher the electric field voltage,the lower the dust concentration at the outlet,and the higher the dust removal efficiency.It is necessary to find the voltage value with the lowest energy consumption on the premise of meeting the dust removal efficiency.An engineering application test of high temperature electrostatic precipitator technology was conducted in a copper smelter in Fujian.The test results showed that the dust concentration in the flue gas at the outlet of the high temperature electrostatic precipitator decreased from 2.19 g/m^(3)to 62 mg/m^(3),and the dust removal efficiency was greater than 97.1%.
