含尘气流中粉尘—泡沫间相互作用的理论研究

ompared to other ways of dedusting, foam-dedusting has many merits, such as the efficiency is high and water comsumption is low, ect. In order to analyze the mechanism of foam dedusting, on the basis of single particle, the theory that interception, inertial impaction, diffusing, and adsorption dominant in the process of the collision between the foam and dust is proposed.Besides, this paper carries out a theoretical analysis based on hydromechanics theory, which can be applied in the calculation of the efficiency of the dust collection, and according to this, a conclusion that increasing the single foam dedusting efficency and foam density are the efficient pathes to increase the overall collection efficiency, which will be benefit to the dustproof jobs in coal mines.
