AI Technical Summary
Traditional mechanical stirring or wall-mounted slow-release methods for dissolving and mixing polymers are time-consuming and short-lasting, making it difficult to control the mixing effect and affecting their application in pipeline systems.
Design a pipeline drag reduction and vibration suppression device, including a shell, an annular filter element and a packing chamber. The packing chamber is filled with spherical particles, and a high molecular polymer liquid is uniformly introduced through a flow guiding structure. Slow release and mixing are achieved by using a porous medium flow channel. Combined with a spiral guide plate, the fluid path is optimized to enhance the mixing uniformity.
It achieves full dissolution and mixing of polymer molecules, delays turbulent transition, suppresses pressure pulsation, reduces flow resistance, improves flow efficiency and acoustic performance, and does not affect the mainstream flow in the pipeline.
