The scheme that current oil-water separator adopts is inflated type oil-water separator, air saturator type oil-water separator, jetting type oil-water separator.Inflated type oil-water separator is containing inflation micropore on eddy flow tube wall, uniformly but shortcoming is easily blocking in inflation, air saturator type oil-water separator bubble diameter is more uniform, fine and close, but it is many that shortcoming is corollary equipment, containing the flow process that the series such as dissolving, circulating pump, air compressor machine, liquid-level switch are loaded down with trivial details, inconvenient operation, is not easy to management.Jetting type oil-water separator simple and practical flow, auxiliary facility is few, but shortcoming is requirement injector designs requirement height, and bubble produces the bigger 30-50um of particle diameter, and the seriation of ejector is also more difficult, limits the product seriation of oil-water separator.
In view of above-mentioned many reasons are necessary to develop a kind of novel compact cyclone oil water separator equipment to overcome disadvantages mentioned above.
Summary of the invention
The present invention is directed to drawbacks described above, it is therefore intended that provide a kind of unit combined with air supporting by eddy flow, it is achieved oil-water separation, reach the purpose of efficient degreasing.
It is: the present invention includes cylinder (7) that cylinder (7) is internal is provided with the some Taper Pipes (8) rotated, and described Taper Pipe (8) one end is provided with allotter (6), and cylinder (7) two ends are provided with adpting flange (9) for this technical solution used in the present invention；Described two flanges (9) outside is respectively equipped with dividing plate, and what be wherein in allotter (6) one end is dividing plate one (5), and the other end is dividing plate two (10)；
Described dividing plate one (5) outside is provided with shrouding (3), and formation oil extraction space between described dividing plate one (5) and shrouding (3), there is outage allotter (6) corresponding position that is connected with dividing plate one (5), is provided with outside oil drain out in oil extraction space；
Described dividing plate two (10) outside is connected by flange and end socket (11), and described Taper Pipe (8) extends in end socket (11)；
Described Taper Pipe (8) is gradually reduced to its cross section of the other end by allotter (6) one end.
