ABSTRACT:
A deaerator for removing gases from complex liquids such as pulp slurries in accordance with one aspect of the invention includes an elongated tubular body adapted to be disposed in a generally horizontal position and having an inlet end and an exit end for the flow of liquid therethrough. A chamber adjacent the exit end is provided for accumulating gases therein and a gas removal vent is associated with such chamber. A set of longitudinally extending vertical baffles are disposed in a lower portion of the tubular body, between which baffles a main portion of the liquid flows. A set of lateral baffles extend across the interior of the tubular body, such lateral baffles projecting above the longitudinal baffles and being spaced apart along the tubular body. The lateral baffles are also spaced from the top wall of the tubular body to define therebetween a flow channel along which bubble-containing liquid is guided toward the chamber. The longitudinal baffles serve to create low velocity regions in the liquid adjacent the upper portions of such baffles thus promoting the rise of gas bubbles upwardly. The lateral baffles assist in catching or skimming off the rising bubbles and also direct same into the flow channel.
