ABSTRACT:
Apparatus for treating gas or vapor includes an impeller arranged in a conduit which draws dusty or fume-laden air through the duct. One or more nozzles are arranged to spray fine droplets of water onto the impeller. Downstream of the impeller, a set of angled collection plates collect the fine water droplets emitted by the nozzle, together with dust or fumes collected by the droplets. The nozzle is connected to a high voltage source, so that the droplets emitted by the nozzle are electrostatically charged. This causes them to attract dust particles and other contaminants. The collection plates are earthed, so that the charged droplets are attracted to them, improving the effectiveness of the apparatus.
