<p>PURPOSE:To provide a washing method and a washing device for removing smoke dust accumulated in a dust collecting pass of an electric dust collector. CONSTITUTION:An electric dust collector 1 is constituted by arranging vertical dust collecting electrode plates 4 in parallel. Jet mechanisms 10, 13, 16, in which lateral fluid pipe materials 8, 11, 14 are provided with jet nozzles 9, 12, 15, are made to face to the dust collecting current inflow and outflow sides of a dust collecting pass 5 of the electric dust collector 1. The 1st, the 2nd and the 3rd stages where foamy washing liquid composed of a detergent and air, water and air, and only air are jetted from the jet mechanisms 10, 13, 16, respectively, into the dust collecting pass 5 are operated in this order. In the 1st stage, the whole surface of the dust collecting electrode plates 4 is washed with the foamy washing liquid, and in the 2nd stage, the washing liquid is washed with water, and in the 3rd stage, water for washing in the 2nd stage is scattered.</p> |
