Rotating coalescer with keyed drive

摘要

A gas-liquid rotating coalescer includes first and second sets of one or more detent surfaces on a rotary drive member and a driven annular rotating coalescing filter element which engagingly interact in interlocking mating keyed relation to effect rotation of the coalescing filter element by the rotary drive member. Designated operation of the coalescer requires that the coalescing filter element include the second set of detent surfaces. A coalescing filter element missing the second set of detent surfaces will not effect the noted designated operation.

1. A gas-liquid rotating coalescer separating liquid from a gas-liquid mixture, comprising:
a coalescing filter assembly comprising a housing having an inlet receiving said gas-liquid mixture, a gas outlet discharging separated gas, and a drain outlet discharging separated liquid, an annular rotating inside-out flow coalescing filter element in said housing, the filter element having an endcap, a drive shaft, a rotary drive member coupled to the drive shaft, said rotary drive member positioned between said drive shaft and said endcap when said annular rotating coalescing filter element is received in said housing, a first set of one or more detent surfaces on said rotary drive member, and a second set of one or more detent surfaces on said endcap of said coalescing filter element, said second set of one or more detent surfaces engagingly interacting with said first set of one or more detent surfaces in interlocking mating keyed relation to effect rotation of said coalescing filter element by said rotary drive member.
