Abstract

Wetting device for wetting and dissolving polymer powders without forming lumps and globular 'fish-eyes' which clog the system apparatus. A nozzle holder has an annular passageway disposed therein which communicates with each of a plurality of spaced jet spray nozzles secured to the holder on a bottom face thereof in the form of a ring. Alternate nozzles spray inwardly forming a turbulent curtain of water. Remaining nozzles spray outwardly against inner wall of a spray confining cylinder to wash down polymer therefrom. An open-ended, powder receiving, tubular flexible insert extends through a central opening of the nozzle holder creating an annular space around the flexible insert. Water supplied to the passageway sprays from the nozzles to induce a downward airstream in the annular space to aid in drawing powder through the insert while simultaneously maintaining the powder in a finely divided state when falling into the turbulent curtain of water.
