Patent ID: 7640973

Claim:
A device for diversion of cavitation flowback from an underground well, comprising a tubular inlet portion, a conical containment shell having a small end and a large end, an inlet opening at a said small end of said conical shell and a discharge opening at said larger end, a conical diverter assembly having a small end and a large end and being centrally disposed within and generally coaxial with said containment shell, said conical diverter assembly further comprising a replaceable nose piece axially mounted on said small end of said diverter assembly, wherein said flowback is directed into the inlet opening of the containment shell along the central axis of the containment shell and against the small end of said conical diverter assembly, said flowback being thereby redirected toward an inner surface of said containment shell, said flowback generally following a path along said inner surface toward the larger end of the containment shell, said flowback exiting the containment shell through said discharge opening, wherein the path of said flowback between said inlet opening and said discharge opening is essentially unobstructed.
