Title:
WET-TYPE ELECTRIC DUST COLLECTION DEVICE AND DUST REMOVAL METHOD
Document Type and Number:
WIPO Patent Application WO/2014/014090
Kind Code:
A1
Abstract:
Provided are a wet-type electric dust collection device and a dust removal method in which the SO3-mist removal performance is increased using a simpler device. A wet-type electric dust collection device for removing dust and low-concentration SO3 mist contained in a gas, wherein the wet-type electric dust collection device has an electrical field formation part in which a plurality of discharge electrodes (18) are provided on opposing surfaces of a first electrode (14) and second electrodes (15)for forming a DC electrical field. The discharge electrodes (18) of the first electrode (14) and the discharge electrodes (18) of the second electrodes (15) generate corona discharges that are reversed in polarity relative to each other. The gas containing the SO3 mist and the dust is guided to the electrical field formation part without electrically charging the SO3 mist and the dust or spraying a dielectric in the gas, and while the gas flows between the electrodes (14, 15), the corona discharges impart electric charges of alternately reversed polarity to the SO3 mist and the dust. The first electrode (14) and the second electrodes (15) collect the charged SO3 mist and dust.
