Abstract

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.
