Mechanism And Experiment Studies On Wet Honeycomb Lamilloy Dust Collector

Growing underground coal dust pollution has caused that coal dust explosion accidents occurfrequently and pneumoconiosis disease spreads, a serious threat to the safe production ofunderground coal mine and underground miners’ physical and mental health. In this paper, throughthe study of wet dust removal mechanism, combine with the research that perturbation by karmanvortex-street in turbulent boundary layer outer region to coupling of boundary layer becomes eddyviscosity, forming a honeycomb filler attachment dust theory, on this basis combining withnumerical theory and CFD simulation, carry on the mathematical modeling to dust removal deviceand the numerical simulation to the dust removal performance of dust collector; Then according tothe theory, design and build the corresponding experimental platform, investigate experimentallythe wet honeycomb lamilloy dust collector, test and verify the accuracy of numerical simulationresults. Comparative results show that the experimental data coincides basically with thenumerical simulation results, proving that the dust removal principle of wet honeycomb lamilloydust collector is reasonable and efficient, and providing a theoretical and technical foundation forthe industrial application of wet honeycomb lamilloy dust collector.
