What is the fundamental difference between dynamic separators and static separators?
Thread Content
I recently came into contact with separators, but what is the fundamental difference between dynamic separators and static separators? I still don’t quite understand it. I’d like to ask for some advice, thank you
There are no mixing elements such as corrugated plates inside the static mixer, nor is any external power required; instead, the mixing of the fluid is achieved through the pressure drop of the fluid itself, that is, the pressure energy resulting from the pressure drop supplies the energy needed for mixing； Dynamic mixers, such as devices that use the rotation of agitators or pump impellers to mix fluids, rely on external power to provide the energy required for mixing.
A dynamic separator functions to separate substances as the liquid flows, while a static separator carries out separation automatically when the liquid is at rest
One has only the flow velocity of the medium itself, while the other has an external driving force； This is the essential difference
The three people upstairs – from elementary school, middle school, and university – none of them really understand it
Well, let me explain my reasons. Look at what the original poster asked: the fundamental difference between dynamic separators and static separators. Is what they answered really considered a fundamental difference? First, a first-year university student spent quite some time answering the question about the difference between dynamic mixers and static mixers. Secondly, for the third-grade students in primary school: is the material inside the static separator truly at rest? Isn’t this misleading people? It’s very likely that he knows even less than the original poster does, so he just answers randomly. The last third part is also incomprehensible – something about the flow rate of the medium combined with external force, and it even goes so far as to claim that separation can occur simply due to the flow rate of the medium itself.
I can’t give a very reasonable answer either. The difference can only be explained based on the principle of separation: the common point is that the two phases must be immiscible and have a density difference. A static separator achieves the separation of the heavy and light phases through gravity, while a dynamic separator relies on the centrifugal force generated by a centrifuge to separate the heavy phase on the outside from the light phase on the inside. Additionally, I’ve heard of a semi-dynamic separation method; I’m not very familiar with it, so I’d appreciate some guidance.
