<p>PURPOSE:To make the washing of dust collecting polar plates efficient by forming a water film having the distribution of different water quantity for a pair of corners selected from two pairs of corners of the box type-shaped dust collecting poles. CONSTITUTION:A box type-shaped dust collection box 26 is constituted by providing the dust collecting poles 5 to four faces and providing the discharge wires 4 to the centers thereof. The nozzles 25-1, 25-2 forming the water film having the distribution of different water quantity are provided to a pair of corners selected from two pairs of corners. By this method, when the dust collecting operation is performed by passing always washing water, the dust collecting polar plates are efficiently washed and the dust collecting efficiency is enhanced.</p> |
