Analogy research on wet fiber layer filtration resistance of mine dust

为提高矿山粉尘收集效率,对除尘器湿式过滤层纤维丝过滤阻力进行理论分析,建立粉尘粒子通过除尘器湿式纤维丝时的阻力理论模型,自行设计了湿式纤维层过滤实验模拟系统,模拟矿山粉尘特点进行了实验研究,对理论模型参数进行了无量纲修正,进一步完善粉尘湿式过滤的阻力理论公式.实验表明,该理论在实际应用中具有较高的准确性.经修正后的理论曲线不仅与实验曲线的趋势保持一致,同时数值上也基本吻合,具有良好的代表性.

To raise the efficiency of dust collection, theoretical analysis on filtrating resistance about the fiber of wet filtering layer precipitator was carried on, and the theoretical model about filtration resistance of dust when it passed the wet fiber layer precipitator was built. Filtration experiment simulation system of wet filtering layer was designed, characteristics of mine dust was simulated with experiment study, the dimensionless parameter of theoretical model was modified, and the theory formula for resistance of dust wet filter was optimized. Results showed that this theoretical model possessed high accuracy and can be applied in practice. It has exhibited good representation, not only did the tendency of theoretical curve is in agreement with the test curve, but also the result basically agreed well with calculated value, as mended.
