Optimization of the Length of the Mist-eliminator Blades for Small Size Water Powered Scrubber
The dust control in anthracite mines in Korea has been important in preventing pneumoconiosis, commonly known as the black lung disease among miners. Portable water-powered scrubber is one of the most effective devices used for dust collection in underground mines or tunnels in Korea. However, there is insufficient information about the design of mist eliminator blades or their performance under different operating conditions of a small size scrubber. In this study, we investigated the possibility of reducing the size of the present water-powered scrubber and the detailed performances of different types of mist-eliminator blades under various working conditions. A full-scale apparatus has been constructed to study the performance of each bend on the mist-eliminator blades. A special gravity-settling chamber and seventeen sets of mist-eliminator blades have been designed and constructed in the laboratory. The results show that the length of the mist-eliminator blades chamber can be reduced by using mist eliminator blades with 42° deflection angle, eight bends, and bend length of 3 cm. Blades having these specifications were the most effective in achieving high dust and coal collection efficiencies within a small distance along the mist eliminator blades. Based on these results, the length of the water powered scrubber can be reduced to 95 cm without significantly decreasing the dust and water collection efficiencies.
