Abstract

PURPOSE:To prevent a electrostatic filter from corrosion and clogging of electrodes and improve dust-collecting efficiency and bypassing waste gas through electrically insulating granular material between a high voltage electrode and earthed electrodes. CONSTITUTION:Title electrostatic filter is composed of filler layer 4, 5 consisting of granular insulating material such as lime. The filler layers 4, 5 are formed by an upper stream earthed electrode 1 positioned on the upper stream in waste gas supply and a clownstream earthed electrode 3. A high voltage electrode 2 is interposed between the earthed electrodes. The layers 4, 5 are spaced away from each other by the electrode 2 so that both layers are not mixed with each other when the filler is moved. High voltage 6 is applied to the electrode 2. Waste gas from a duct 11 is passed in the direction of the arrow through the filter. Dust is collected on the surface of the filler. The filler within the layer 4 is always withdrawn through a pipe 7. The filler within the layer 5 is intermittently withdrawn. Dust is separated from the filler by means of a vibration sieve 9. The filler is supplied to the filler layer. The electrodes 1, 3 are formed by angle steel, and the electrode 2 is formed by using expanded metal.
