Abstract

PROBLEM TO BE SOLVED: To provide an electric dust collecting apparatus for efficiently recovering dust adhering to dust collecting electrodes. SOLUTION: This electric dust collecting apparatus 7 comprises electric discharge electrodes 8 and dust collecting electrodes 4 mutually coupled and arranged in the air flow route of a box body. While transversely crossing an air flow route outlet, the dust collecting electrodes 4 are installed in the flow route outlet and a hammering mechanism 9 is installed in the dust collecting electrode 4. The electric discharge electrodes 8 having projections 5 only on the upstream side are installed on the downstream side of the dust collecting electrodes 4. Since dust discharged out of an outlet of the electric dust collecting apparatus 7 adheres to the dust collecting electrodes 4 on the upstream side by the electric discharge plate 8 in the final stage, dust removing efficiency is heightened by adding a small number of rows of electrodes. Moreover, even if the dust collecting electrodes 4 are hammered by recovering dust, the dust floating again adheres to the dust collecting electrodes 4 on the upstream side by the electric discharge plate 8 in the final stage, so that visible smoke evolution can be prevented and dust can efficiently be recovered.

As described above, according to the present invention, a plurality of dust collecting plates are provided across the flow path at the outlet of the flow path of the electric precipitator, and a discharge plate discharging only upstream is provided downstream of the dust collecting plate. Since it is an electric precipitator installed, the dust removal performance can be improved by adding only a small number of arrays, and even if the dust collection plate is hammered to collect the dust, the re-floating dust is discharged by the final discharge plate. Since it re-adheres to the dust collecting plate on the upstream side, generation of visual smoke can be prevented. Further, in a cross-flow type electrostatic precipitator, the above effects can be obtained only by providing a discharge plate, and the construction cost can be reduced. In addition, by dividing the plurality of dust collecting plates and hammering them at a different timing with a small force, the amount of fall increases and the total amount of re-suspension decreases, so that dust can be collected more effectively.
