Abstract
Apparatus for metering and/or distributing liquid media comprising a substantially horizontal manifold and a plurality of generally vertical discharge conduits which depend from said manifold, said discharge conduits comprising discharge tubes which are open at both ends and are liquid-tightly fitted in and depend from said manifold, each of said tubes having a top end disposed in an upper portion of the manifold and at least one lateral opening disposed above a joint between said tube and the manifold and within said manifold.
Claims6
A process for supplying a liquid treating agent to a flowing stream which flows in a generally horizontal path which comprises passing said liquid stream along said generally horizontal path in said channel, feeding said treating agent into a substantially horizontal manifold at varying amounts, said manifold being connected to a plurality of generally vertical discharge conduits which depend from said manifold, said discharge conduits comprising discharge tubes which are open at both ends and are liquid-tightly fitted in and depend from said manifold, each of said tubes having a top end disposed in an upper portion of the manifold and at least one lateral opening disposed above a joint between said tube and said manifold, and within said manifold, each of said discharge tubes having a hose attached to its lower end which hoses have outlet openings, said outlet openings being substantially uniformly distributed over the cross-section of flow of fluid of said flowing liquid, said hoses disposed in said flowing liquid such as to be pendulum-like oscillatable by said flowing liquid, whereby when liquid treating agent is passed through said manifold in an amount sufficient to pass through said lateral opening, but not through said top end, said treating agent is uniformly dispensed in said flowing liquid at a first dosage level and when said liquid treating agent is passed through said manifold in an amount sufficient to pass both through said lateral opening and said top ends, said treating agent is uniformly dispensed in said flowing liquid at a second dosage level.
An apparatus for metering liquid treating agent to the plurality of dosage levels at different times into a liquid flowing through a channel which comprises a channel, means for flowing liquid to be treated through said channel, a substantial horizontal manifold, means for supplying said liquid treating agent at different amounts to said manifold, a plurality of generally vertical discharge conduits, each of which depend from said manifold and are in fluid communication therewith, said discharge conduits comprising discharge tubes which are open at both ends and are liquid-tightly fitted in and depend from said manifold, each of said tubes having a top end disposed in an upper portion of the manifold and at least one lateral opening disposed above a joint between said tube and said manifold, and within said manifold, each of said discharge tubes having a hose attached to its lower end which hoses have outlet openings, said outlet openings being substantially uniformly distributed over the cross-section of flow of a fluid, said hoses disposed in said liquid flowing through said channel such as to be pendulum-like oscillatable by said flowing liquid, whereby when liquid treating agent is passed through said manifold in an amount sufficient to pass through said lateral opening but not through said top end, said treating agent is uniformly dispensed in said flowing liquid at a first dosage level and when said liquid treating agent is passed through said manifold in an amount sufficient to pass through said lateral opening and said top end, said treating agent is uniformly dispensed in said flowing liquid at a second dosage level.
