A process of breaking up a foam into a liquid component and a gaseous component by action of centrifugal forces, includes drawing the foam axially into a centrifugal fan device by suction; then, accelerating the foam radially by centrifugal forces over a plurality of ribs and/or baffles, forcing the liquid component through a peripheral liquid discharge outlet; feeding the gaseous component through at least one gas outlet prior to forcing the liquid component through the liquid discharge outlet; advantageously feeding the gaseous component in a radial direction opposite to that in which the foam flows in the fan device, and after that, conducting the gaseous component axially through a gas outlet. The apparatus for performing the process includes a centrifugal fan acting as a pump impeller having an upper plate and a lower plate connected by a plurality of ribs and a conical cutoff cover located above the centrifugal fan acting to guide gas component flow, an axially-located foam inlet, a gas component outlet located above the cutoff cover near the rotation axis of the fan and a liquid discharge outlet formed between the cutoff cover and the lower plate at the periphery of the centrifugal fan.
In a process of breaking up a foam into a liquid component and a gaseous component by action of centrifugal forces, comprising drawing the foam in one axial direction by suction and then accelerating the foam in another radial direction by action of the centrifugal forces, the improvement comprising feeding the gaseous component through at least one gas outlet prior to forcing the liquid component through a liquid discharge outlet.
A process of breaking up a foam by action of centrifugal forces, comprising the steps of:
In an apparatus for breaking up a foam into a liquid component and a gaseous component, comprising a centrifugal fan device including a centrifugal fan having an axis and acting as a rotatably driven pump impeller, said centrifugal fan device having an inlet, a gas outlet and a liquid discharge outlet in the vicinity of the centrifugal fan periphery, the improvement wherein the inlet is located in the vicinity of the axis of the centrifugal fan and the gas outlet is located centrally relative to the centrifugal fan and in the vicinity of the axis of the centrifugal fan.
In an apparatus for breaking up a foam into a liquid component and a gaseous component, comprising a centrifugal fan device including a centrifugal fan having an axis and acting as a rotatably driven pump impeller, said centrifugal fan device having an inlet, a gas outlet and a liquid discharge outlet in the vicinity of the centrifugal fan periphery, the improvement wherein the inlet is located in the vicinity of the axis of the centrifugal fan and the centrifugal fan comprises an upper plate and a lower plate connected by a plurality of intervening ribs and the gas outlet is located centrally relative to the centrifugal fan and in the vicinity of the axis of the centrifugal fan, having a central opening acting as at least a part of the inlet and a cutoff cover which forms a throttling gap with the lower plate at an outer peripheral edge thereof.
An apparatus for breaking up a foam into a liquid component and a gaseous component, comprising a centrifugal fan device including a centrifugal fan having a fan rotation axis and comprising an upper plate and a lower plate having a plurality of intervening ribs connecting the upper and the lower plates, said upper plate having a plurality of outlet openings acting as orifices for said gaseous component and said lower plate having a central opening acting as an inlet for the foam together with a inlet pipe;
