Description
Technical field
The present invention relates to the Drag Reduction technical fields of fluid line conveying, especially a kind of to be realized based on electrolysis microbubble
The drag reduction pipe of fluid drag-reduction.
Background technology
Energy-saving and emission-reduction are one of the main problem that countries in the world are paid close attention at present, wherein trying to reduce in fluid delivery process
Frictional resistance and the conveying speed for improving fluid are an important topics in energy-conserving and emission-cutting technology field.In numerous related fluids
In pipeline velocity increased by resistance reduction technical field, because Friction Reduction by Micro-bubbles technology have drag reducing efficiency high (up to 80%), do not bring it is secondary
The advantages of pollution, receives academia and engineering circles favor.Although microbubble turbulent flow drag reduction technology has drag reducing efficiency height and without secondary
The advantages that pollution, but because microbubble be not easy to prepare and prepare microbubble can extraly consume certain energy, reduce it is energy saving
Effect, to limit application of the Friction Reduction by Micro-bubbles technology in Practical Project field.Therefore, carry out existing energy consumption in not extra band
On the basis of, how Friction Reduction by Micro-bubbles technology to be efficiently introduced into the pipeline of engineering practice fluid, reduce fluid hose
The frictional resistance of road conveying is a problem to be solved；
It is well known that the wall thickness of pipeline is generally relatively thin, the slot of installation electrolysis ring can not be opened up out on the inner wall of pipeline
Shape structure, therefore the drag reduction pipe in currently available technology is using external connection structure inside pipeline that electrolysis ring is directly solid
It is scheduled on inside pipeline, this also necessarily causes the outer diameter of electrolysis ring to be less than the internal diameter of pipeline, and this structure has more drawback, main
It is embodied in the following：One, the handling of electrolysis ring are relatively complicated, are unfavorable for being electrolysed the replacement of ring, practical application is difficult；Two,
Complicated, performance difficulty, it is of high cost；Three, since the outer diameter of electrolysis ring is less than the internal diameter of pipeline, it is clear that electrolysis ring itself
Meeting convection current body forms certain resistance, while the amount being electrolysed at the microbubble arrival pipeline wall surface that ring electrolysis generates is not also high, greatly
Part microbubble can be in the intermediate position of pipeline, therefore cause drag-reduction effect unsatisfactory.
Invention content
