摘要

摘要: 针对餐饮油烟中细颗粒物和挥发性有机物（VOCs）的复合污染控制难题，构建了齿-柱电极结构（预荷电单元）与板-板电极结构（即颗粒物收集单元）组成两级ESP系统，以氯化钾颗粒物和甲苯气体模拟餐饮油烟中气固混合组分开展系统研究。结果表明：当齿-柱荷电电极电压为+12 kV，板-板集尘电极电压为-8.5 kV时，臭氧浓度为176.9 mg/m³，粒径＜0.3 μm的细颗粒物的收集率达到了91%，颗粒物的总收集率则超过了98%；颗粒物的存在可以促进甲苯的降解，通入颗粒物前后，甲苯去除率由29.2%提高到53.1%。该研究成果可为餐饮油烟中复合污染的协同处理提供技术支持。

Abstract: Addressing the complex pollution control challenge of fine particulate matter and volatile organic compounds （VOCs） in catering fumes， this paper constructed a two-stage ESP system consisting of a sawtooth-rod electrode structure （preloading unit） and a plate-plate electrode structure （i.e.， particle collection unit）， and conducted systematic research on the gas-solid mixture components of the simulated catering fumes， using potassium chloride particles and toluene gas. The experimental results showed that when the voltage of the sawtooth-rod charged electrode was +12 kV and the voltage of the plate-plate dust collection electrode was -8.5 kV， the ozone concentration was 176.9 mg/m³， and the collection efficiency of fine particles with a particle size <0.3 μm reached 91%， while the total collection efficiency of particles exceeded 98%； the existance of particles can accelerate the removal of toluene， and after injecting particles into the system， the degradation efficiency of toluene increased from 29.2% to 53.1%. The research results can provide technical support for the collaborative treatment of compound pollution in catering fumes.
