3. How Hualai vane pack mist eliminator works?
When the gas containing the mist flows through the vane pack demister at a certain speed, due to the inertial impact of the gas, the
mist and the wave plate collide and are attached to the wave plate
surface. The diffusion of the mist on the surface of the corrugated
plate and the gravity settlement of the mist cause the mist to form
large droplets and move forward with the air flow to the turning of
the corrugated plate. Because of the centrifugal force of the
steering and its friction with the corrugated plate, the adsorption
and the surface tension of the liquid, the droplets become larger
and larger until the concentrated droplets are dragged by big
enough gravity generated by themselves, which exceeds the lifting
force of the gas and the surface tension of the liquid. When the
force is applied, the droplets are separated from the surface of
the vane plate. The multi fold structure of the wave plate of the mist eliminator increases the chance of catching and gathering the mist, and the
uneliminated mist will catch and gather at the next turn through
the same function, so it will work repeatedly, thus greatly
improving the efficiency of mist eliminator. After the gas passes
through the wave plate demister, there is basically no mist.
