One kind of jet sieve VIV suppression apparatus and method

The present invention relates to a jet sieve VIV suppression apparatus and method, comprising: means for the injection pipe, U-diversion pipe, the bottom of the screen exhaust, exhaust screen, top vent screen, composition of gas distribution plate, a bottom plate and the top eight parts. Set in the riser vent screen, the injection tube through the U-shaped bend diversion to the high-pressure air into the exhaust screen with the riser annulus, the air flow from the exhaust vent on the screen, destroyed sea ​​boundary layer flow around the surface of the pipe, while interfering with the formation of the tail pipe vortex effectively suppresses the vortex-induced vibration. The present invention is able to respond to flow in different directions, not easy to corrosion and damage, follow the construction site when the partition into the water pipes under the sub-section does not affect the normal construction process, after the completion of construction can be recycled, saving costs.
