(54) Particulate matter extraction device


(57) The device is for extracting gas-borne particulate matter from a partly enclosed space through which a mass of bulk material is being conveyed. The device comprises a casing having an entry end and an exit end arranged to allow a conveyor to move through the casing in order to convey a mass of bulk material through the casing. The device includes a duct mounted on the casing and having an inlet which communicates with the casing so as to extract gas-borne particulate matter from the casing and an outlet communicating with the casing in order to return the particulate matter to the casing. A liquid nozzle is arranged in the duct so as to direct a jet spray of liquid in a direction towards the outlet and thereby induce a flow of gas-borne particulate material into the duct through the inlet thereof and which material is wetted prior to return of the material to the casing via the outlet. The outlet being arranged in use to direct the wetted material downwardly onto a collection surface located in the casing.
