Cyclonic jetting technology is an offshoot of solid-liquid hydrocyclone technology. The unit is a modified hydrocyclone with the cone/apex removed to allow for shielded vortex combined spray and suction flow.
Note: Please read post B-FSM-049 first to reference the flow patterns of a solid-liquid hydrocyclone and desander.
Cyclonic Jetting Device Flow Pattern
Refer to the graphic below pertaining to the flow pattern description.
- The cyclonic jetting device is a solid-liquid hydrocyclone with a truncated or absent cone.
- The vortex finder is extended past the body cylinder – into the section where the cone would normally be present.
- These geometric changes allow for uncoupled vortices – i.e. the irrotational outer and rotational vortices are separated resulting in two irrotational vortexes
- The annular vortex fluidizes the surrounding settled sand while the center vortex captures the suspended sand particles
- A cyclonic jetting device operates with a pressure differential ratio (PDR) from 1.3-1.5 to balance the flow split (S)
- These vortexes result in shielded vortex sand removal from the vessel. This operation prevents turbulence above solids removal zone. The solids are fluidized, captured, and transported in one compact device.
