Abstract (en)

[origin: EP4082668A1] An electrostatic precipitator includes a charging portion including two charging electrodes opposite to each other, the charging portion being configured to charge a particulate matter in a gas passing between the two charging electrodes by applying a first voltage between the two charging electrodes to generate a corona discharge; and a collection portion including two collection electrodes opposite to each other, the collection portion being configured to collect by a Coulomb force the particulate matter charged by the charging portion by applying a second voltage between the two collection electrodes. One collection electrode of the two collection electrodes surrounds a hollow space, and an opening to open the hollow space is formed in a part of the one collection electrode facing the other collection electrode.
