Abstract
A method for washing the media bed of a gas pollution abatement reactor which includes using a bed washer apparatus which includes a continuous tubular manifold having a plurality of spaced downwardly directed nozzles directing liquid onto the bed supported on a frame, a drive wheel supports the frame, and a motor driving the drive wheel in at least two directions inside the reactor. The manifold is connected to a source of liquid and the apparatus includes directional control switches for reversing the direction of the drive wheel. In this method the reactor is first taken offline and the media bed is cooled to ambient temperature. The components of the washer are disassembled and then re-assembled inside the reactor and the manifold is connected to a source of wash liquid. The washer traverses the media bed, uniformly washing the media bed to remove particulate contaminants without requiring personnel inside the reactor while the media is being washed.
