Technological and economical analysis on particle removing

Provided a theoretical basis for the selection of particulate catchers while particle pouutant, analyzed particulate catchers' removal efficiencies of Total Suspended Particles (TSP) and Inhalable Particle (PM₁₀). Economic analysis was performed from equipment investment, operating expenses and depreciation expenses. Removal expenses of TSP and PM₁₀ for different particulate catchers were gained. Of high-efficiency catchers, removal expense of Venturi scrubber is highest and that for electrostatic precipitator is lowest. Removal expenses of PM₁₀ are much higher that of TSP for medium-efficiency catchers and there is not distinguish difference for high-efficiency catchers.
