Abstract	Dust particles in blast furnace gas deposit easily on the bottom of sealing surface of the butterfly valve seat in pipelines, which will bring jams to the valve plate, and thus affect normal production of the blast furnace and cause serious economic losses. In order to get flow field characteristics near the butterfly valve, obtain the deposition process of dust particles on the bottom of the valve seat sealing surface and provide a reference for design of the automatic dust removal device, butterfly valve flow field models with different valve plate openings was built using Pro/E. Meanwhile, a mixed gas phase model of CO2, CO and N2 was established, and a dust particle size distribution model using Rosin-Rammler distribution function was constructed according to the actual working condition of blast furnace. Basing on FLUENT module of ANSYS Workbench, the influences of valve plate opening and dust particle size on dust deposition process in the flow field was simulated. Results show that the deposition rate grows with the increase of the particle size, and the deposition mass comes to the largest when the valve plate opening is 15°.
