Description

Technical Field

[0001] The utility model relates to the technical field of crude oil pipeline drag reducer slurry mixing, in particular to a crude oil pipeline drag reducer slurry mixing device for uniformly stirring. Background Art

[0002] The drag reducer is composed of high molecular hydrocarbon polymer, which is a viscous substance of non-Newtonian fluid. The oil-soluble drag reducer used for oil drag reducer has an extremely long chain structure, and the chain structure is soft and elastic. The friction resistance of the fluid limits the flow of the fluid in the pipeline, resulting in reduced pipeline output and increased energy consumption. The polymer drag reduction method is to inject a small amount of high molecular polymer into the fluid to reduce the flow resistance under turbulent conditions. The chemical agent used to reduce the flow resistance of the fluid is called a drag reducer. Drag reducers are widely used in crude oil and refined oil pipeline transportation. It is an important means to improve the pipeline flow capacity and reduce energy consumption in specific areas. After the drag reducer is added to the pipeline, the gravitational resistance force between the drag reducer molecules reacts to the fluid, changes the direction and size of the fluid, and converts part of the radial force into an axial force in the downstream direction, thereby reducing the consumption of useless work and achieving the effect of reducing friction resistance loss in a macro sense. However, most of the crude oil pipeline drag reducer slurry mixing devices that are uniformly stirred can only perform stirring operations in the same direction, which often leads to insufficient stirring, making it difficult to meet the requirements of uniformly stirring the drag reducer, affecting the stirring quality of the device.
