Wind makes the air-flow containing drop enter the present apparatus, and air-flow is advanced past gas-liquid separation zone along curved surface channel spiral, gas-liquid separation zone to
Inside gradually curved tapered, the radius curvature that becomes smaller becomes larger, and sectional area becomes smaller, and air-flow is constantly accelerated, and drop is thrown to curved surface channel outer wall,
Complete gas-liquid separation；Air-flow after separation is flowed out through air-flow pooling zone along annulus head cover air stream outlet, and drop is outside curved surface passage
Stream is accumulated on wall, liquid stream is collected by gravity and stream pressure collective effect to channel bottom and circular bottom plate center, accumulation one
Fixed height reversely flows out along airflow inlet or separately opens leakage hole outflow in circular bottom plate.
Gas-liquid separation zone separation angle is the difference of scroll separate sheet total angle of rotation degree and two separate sheet angles（M × 90 ° ﹣
360°/N）, the equiangular spiral arm number of plies is more, and total angle of rotation degree is bigger, and the more separation angles of separation the piece number are closer to total angle of rotation degree point
Digression degree is bigger, and separation angle is bigger, and curvature of curved surface is bigger, and separating effect is better；Separation the piece number is more, and curved surface number of channels is got over
More, single channel cross-sectional area is smaller, and separating effect is better；The smaller curvature of curved surface of separate sheet radius is bigger, and separating effect is better；Point

Scroll separate sheet inner wall intersection）Always compare madial wall（With scroll separate sheet outer wall intersection）Long (i.e. lateral wall
Sweep is more than madial wall sweep), direction from inlet to outlet, the radius curvature that becomes smaller becomes larger, and section is gradually small, air-flow
Pressure and speed constantly change, in turbulent condition；On any one place's airflow direction, air-flow generates Bernoulli effect, i.e.,
Outside flow velocity is big, pressure is small, and inside flow velocity is small, pressure is big, therefore outside pressure differential is formed inside and outside gas-liquid separation zone, bent
Face passage curvature is progressive to become larger, and outside flow velocity is bigger, and pressure differential is bigger, and drop is accelerated by outward pressure effect to gas-liquid separation zone
Lateral wall moves.On any one place's airflow direction, air-flow is influenced to move along a curved path by channel shape, and the inertia force of drop is gentle
Flow drag effect generate centripetal force, the velocity balance of drop relative wind in inertia force gentle flow resistance dynamic balance, drop along
Gas-liquid separation zone is moved with air-flow to the center of circle；Centripetal force weakens when the inertia force of drop is more than gas-flow resistance, and centrifugal phenomenon shows,
