【摘要】 日益严重的井下煤尘污染导致煤尘爆炸事故频繁发生和尘肺病的蔓延，严重地威胁了煤矿井下的安全生产和井下作业矿工的身心健康。本文通过对湿法除尘机理的研究，结合平板湍流边界层外区卡门涡街扰动对边界层的耦合成为复涡黏的研究，形成了蜂窝式扰流滤芯附着除尘机理，在此基础上结合数值理论和计算流体动力学对除尘装置进行了数学建模，并对除尘器的除尘性能进行了数值模拟；然后根据该机理设计并搭建了相应的实验平台，对湿式蜂窝扰流滤芯除尘器进行了实验研究，验证了数值模拟结果的正确性。对比结果表明，实验测量所得数据与数值模拟结果基本吻合，证明了湿式蜂窝扰流滤芯除尘器除尘机理的合理性和高效性，为湿式蜂窝扰流滤芯除尘器工业化应用提供了理论和技术基础。更多还原

【Abstract】 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.更多还原
