される。2. Description of the Related Art Conventionally, this type of wet electrostatic precipitator has been used in combination with a dry electrostatic precipitator to remove dust and mist in a dust-containing gas discharged from a sludge incinerator. That is, the dust-containing gas from the sludge incinerator is first supplied to the cyclone dust collector and the dry type electrostatic precipitator to roughly remove the dust and mist, and then supplied to the wet type electrostatic precipitator to finally remove the dust and mist. It is released and released into the atmosphere. Specifically, the wet electrostatic precipitator uses a dust-containing gas having a dust concentration of about 200 mg / Nm 3 (dry) and a dust concentration of 10 mg / Nm 3 (dr) which is an exhaust standard value.
In order to satisfy y), it is operated with a low dust collection efficiency of 95%.
