Abstract: A venturi scrubber for scrubbing a gas stream to remove undesired gaseous and particulate components. The device includes a scrubber vessel having an external wall, an upper inlet for admitting the gas stream, and a collecting reservoir at the bottom of the vessel for collecting scrubbing liquid. An internal wall extends from the upper part of the external wall to define an axial converging passage for receiving and converging the gas stream from the inlet. An adjoined downwardly extending venturi passage receives the downwardly flowing gas stream from the converging passage, the internal wall abounding the venturi passage terminating above the liquid level at the reservoir; and an annular space is thereby defined between the internal and external walls. An outlet duct for the scrubbed gas stream intersects the annular space at the upper part of the space.

Abstract: A particulate capture system has an air circulating chamber that separates a first portion of particulates trapped within an air stream. The particulate capture system also has a water injection chamber that separates a second portion of particulates trapped within the air stream. The first portion of particulates is separated via circulating air flow. The second portion of particulates is separated via encapsulating the particulates in water and returning the encapsulated particulates to a cooling chamber where the particulates are blended with a bulk product being processed within the cooling chamber prior to collection of the bulk product.
