Abstract
Abstract Flexible sparging devices for distributing ammoniating liquids in apparatus for manufacturing ammonium phosphate fertilizer compositions comprising flexible tubing or hose with multiple escape apertures in the walls thereof. The tubing or hose is closed at the end opposite the inlet and at least the inlet end is secured to a fixed support. Such flexible sparging devices provide infinite loci of distribution due to propulsive force of ammonia ejection and the propensity of such spargers to move from areas of higher to lower fluid density.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
47 words
A sparging device in accordance with claim 1, wherein: a. said tube has a fixed end and a free end opposite said fixed end, b. said fixed end being the open end secured to the ammoniating liquid feed pipe, c. said free end being the closed end.
Claim 2
Dependent Claim
62 words
A sparging device in accordance with claim 1, wherein: a. said tube has fixed opposite ends and a movable portion between its ends, b. one of said fixed ends being its open end which is secured to the ammoniating liquid feed pipe, c. the opposite fixed end being its closed end and being secured to a support provided opposite said feed pipe.
Claim 3
Dependent Claim
58 words
A sparging device in accordance with claim 3, wherein: said tube is attached intermediate its fixed ends to flexible movement-limiting means which allows the intermediate portion of the tube between its fixed ends to flex and move under the pressure of the ammoniating liquid discharging therefrom, but confines the flexing and movements thereof to predetermined limits of amplitude.
Claim 4
Dependent Claim
38 words
A sparging device in accordance with claim 4, wherein: said movement-limiting means comprises a slack flexible supporting cable which is supported at both ends and is attached intermediate its said ends to the intermediate portion of the tube.
Claim 5
Dependent Claim
30 words
A sparging device in accordance with claim 1, wherein: the orifices of said perforated tube are symmetrically arranged circumferentially of the tube to provide symmetrical ejection of the ammoniating liquid.
Claim 6
Dependent Claim
30 words
A sparging device in accordance with claim 1, wherein: the orifices of said perforated tube are asymmetrically arranged circumferentially of the tube to exert asymmetrical jet forces against said tube.
