Abstract: Known wet electrostatic precipitators are large and inefficient. The present invention enables the production of smaller, more efficient and long lasting wet electrostatic precipitators by the addition of a central bore in the inner electrode through which a first purge flow is passed and directed into the precipitator chamber, perpendicular to the direction of flow of the gas to be treated through the chamber to urge the particulate into the water curtain. A second, larger, cleaning purge flow is also provided to disturb the water curtain such that it cleans the inner electrode of any deposited particulate.

Abstract: The present invention provides a wet scrubber for gas abatement, comprising a scrubbing vessel defining a chamber, a gas inlet for supplying a gas to be scrubbed, and a gas outlet for allowing the egress of a scrubbed gas; the inlet and outlet being in fluid communication with one another; one or more scrubbing fluid supply ports; the wet scrubber comprising at least one distribution element connected to a scrubbing fluid supply port for distributing a scrubbing fluid inside the chamber; wherein at least one said distribution element is a distribution plate comprising a cavity and a plurality of apertures arranged to allow scrubbing fluid to flow from the cavity.
