Venturi tube and static mixer

A venturi tube is short for a Venturi pipe. The principle of the Venturi effect is that when wind blows past an obstacle, the air pressure near the inlet on the upwind side of the obstacle is relatively low, which creates a suction effect and leads to air flow. The principle of a venturi tube is actually quite simple: it narrows the airflow to increase its speed, thereby creating a \"vacuum\" zone behind the outlet of the venturi tube. It can use air flow to transport powder materials. 　　It is mainly utilized for its suction effect, such as in vacuum cleaners, powder transfer, coolers, flow meters, dryers, and so on. Suction pumps in the chemical industry operate on the same principle; therefore, the material used depends mainly on the application area, with options such as iron, aluminum alloy, and plastic or nylon. The mixing process in a static mixer is carried out by mixing elements fixed inside the tube. Due to the action of these mixing elements, the fluid rotates sometimes in one direction and sometimes in another, constantly changing its flow direction. This not only pushes the liquid at the center toward the periphery but also pushes the fluid from the periphery toward the center, thereby achieving an excellent radial mixing effect. At the same time, the rotation of the fluid itself also occurs at the interfaces where adjacent elements are connected. Have experience with liquid-liquid and liquid-gas static mixers

Which has a better mixing effect between the two?

Static mixers offer better performance, but here we use them in combination for desulfurization. First, use a venturi tube (commonly known as a extractor) to draw out the alkaline solution along with gasoline or diesel for mixing, and then mix it in a static mixer. Adding a booster mainly saves one pump, which can be considered energy-saving.
