The utility model can also adopt following technical scheme:

The cross section of described feed pipe is that rectangle, longitudinal section are spiral yarn shaped for contraction shape, said three-dimensional body.

The said three-dimensional body of said feed pipe is involute or tangent line shape.

Said baffle plate is discoid.

Advantage and the good effect that the utlity model has are:

1, owing in whirl cylinder, is provided with the adjustable discoid baffle plate of setting height(from bottom); After the physical dimension of device is fixing; Can adjust the size and the setting height(from bottom) of baffle plate through the size of gas-liquid separation amount; The volume that need not aggrandizement apparatus can satisfy the gas-liquid separation of different amounts, has enlarged the scope of application of device fractional dose; Can also effectively stop the lightweight that is separated to get into underflow mutually, can significantly improve the flow regime of device internal flow simultaneously,

2, adopted draw ratio to be merely 2.2: 1～2.6: 1 conical whirl cylinders of weak point; Reduced the radius of gyration; Centrifugal force intensity sharply increases, and has strengthened separating effect, and treating capacity has reached 20～42m3/h; Reduced the volume of device, and remedied the energy loss of fluid in the real work and keep similar gyration at whole main separation zone;

3, adopt the overflow pipe structure of discharging downwards; The position of overflow pipe has replaced that in the flow field position of forced vortex; Thereby reduced the motion energy needed of forced vortex; Solve the battery drain problem that short-circuit flow causes effectively, be implemented in the zero leakage in the broad working condition scope, and played the effect of stable cyclone flow field;

4, whole is adopted welding manner, does not have other bascule spares, and energy consumption is low, and intensity is high, and is simple in structure, need not regular maintenance, is easy to processing and manufacturing, reduced production cost;

5, adopted the three-dimensional spiral of involute or tangent line shape linear, the feed pipe of rectangular cross section, contraction shape vertical section structure: reduced the disturbance and the turbulence of charging aperture place fluid, thereby reduced the local energy loss at charging position; Fluid is quickened at the charging aperture place,, make the gas-liquid separation in the device more effective to strengthen the centrifugal intensity in the cyclone.
