Operation principle one: gas-liquid (mist, the small particle) mixed gas spiral winding sheet by spiral separating device, produces height
Speed centrifugal action, under gravitational and centrifugal forces, drop and dirt that relative density is bigger are poly-on the downside of cylinder outer tube wall
Collection motion, gas gathering motion in upside in cylinder outer tube that relative density is less, partial drop is directly thrown by outage
Go out.Substantial amounts of fine drop and granule collision probability under high speed centrifugation moving condition significantly increases, it is easy to cohesion becomes big liquid
Dripping, drop is thrown to cylinder inboard wall surface, buries in oblivion, discharge from outage, realize further after the liquid film layer contact of wall attachment
The removing of drop.
Operation principle two: after one-level gas-liquid separation, still contains the liquid that part particle diameter is relatively small in mixed gas
Again by the drop of reentrainment after dripping (particle diameter is less than 10 μm) and separating, after flow through venturi, promote the centrifugal motion of air-flow
Speed, improves the centrifugation efficiency of small particle size droplets, and after air-flow flow through venturi, dynamic pressure increases rapidly, and relative static pressure is obvious
Reduce so that the hydrostatic pressure radially that liquid film on wall and granule etc. are subject to reduces, and then well control liquid film
Thickness and air stream outlet state, prevent the reentrainment of drop, it is achieved the second-order separation of gas-liquid.
Operation principle three: flow through venturi separate further after mixed gas, eddy flow enters in equal flow cartridge, by homogenizing plate
Interference, shorten radial motion distance, its inner droplets is buried in oblivion after contacting with the liquid film layer on homogenizing plate, from outage arrange
Go out, realize gas-liquid separation further.
The present invention by the setting of spiral winding sheet make gas produce high speed centrifugation move, the bigger drop carried in gas and
Dust etc. separate with gas owing to centrifugal force gathers cylinder outer tube wall.Spiral winding sheet of the present invention does not has a central shaft, but directly
Connecing spiral, the motion further increasing heterogeneous flow field separates, and the integrated design of spiral winding sheet and cylinder outer tube wall is avoided
The existing conventional design impact for heterogeneous flow field；Venturi tube is equipped with so that air-flow flow through venturi with equal flow cartridge
Impacting on homogenizing plate with faster vortex gas-flow after acceleration, moment changes air motion mode, the drop within air-flow and dirt
After angstrom hitting the liquid film on homogenizing plate, moment buries in oblivion, and further promotes separating effect.The present invention sets on cylinder outer tube wall
It is equipped with particulate collection bar, has further speeded up separation and the collection of flash trapping stage process, beneficially particulate matter, improve separation
Effect, simultaneously facilitates the second-order separation carried out subsequently.
The segregation apparatus based on flow field conversion that the present invention provides can separate the drop of 1-80 μm particle diameter, 10 μm granules
Separation efficiency is 71%, and the separation efficiency of the 10 following granules of μm is anticipated can reach more than 60%, and relatively current techniques is in small particle (10 μm
Separation efficiency below) improves more than 40%.Separation efficiency for the 10 above granules of μm improves about more than 20%.
