Problems solved by technology
At this time, if the above-mentioned cyclone oil-water separator is used to treat sewage with low oil content, the water content of the oil discharged from the oil outlet pipe may be relatively high, especially when separating sewage with large oil content or high viscosity, the effect is relatively poor
In addition, because the pressure of various oily sewage at the inlet is different, or often fluctuates, a stable reverse flow oil core cannot be obtained, and the separated oil cannot flow smoothly from the small oil spill, which may also cause separation. The oil and water remix, which is not desired

Embodiment Construction
[0024] figure 1 An embodiment according to the present invention is shown. In this specification, the same reference numerals denote the same components in different embodiments. From figure 1 It can be seen that the oil-water cyclone separator represented by the number 1 as a whole includes the inlet section 2, the first cone 3 and the steady flow section 7 connected in sequence. The first cone 3 is a circular cone that shrinks downward. The steady flow section 7 is a slender cylindrical tube with an outlet 12 at its tail. The inlet section 2 is a cylindrical straight section, which is provided with at least one tangential inlet 11. E.g figure 2 with 3 As shown, in this embodiment, there are two tangential inlets 11, which are arranged at the same height with an interval of 180°. Of course, it is conceivable to provide other numbers of tangential entrances, wherein each tangential entrance 11 can also be arranged at a different height. The liquid inlet pipe 8 is inserted i...

The invention discloses an oil-water cyclone separator (1), which includes an inlet section (2), a first cone (3) and a steady flow section (7) in sequence; the inlet section (2) is provided with at least one tangential inlet (11); an intake pipe (8) is connected with the tangential inlet (11); the first cone (3) is a round cone and shrinks downwards; the steady flow section (7) is an elongated cylindrical pipe and the tail part of the steady flow section (7) is provided with an outlet (12); the oil-water cyclone separator is characterized in that the separator also includes a second cone or shrinking body (4) arranged above the inlet section (2) and connected with the inlet section (2); the cone or shrinking body (4) shrinks upwards and is provided with a top opening (14).
Description
Technical field [0001] The invention relates to a cyclone separator, in particular to an oil-water cyclone separator. Background technique [0002] With the enhancement of environmental protection awareness, the treatment rate of urban sewage and industrial wastewater in my country is continuously increasing. The treatment of oily wastewater is an indispensable link in most wastewater, especially the treatment of wastewater generated during the treatment of oilfield produced fluids. . [0003] Since the 1990s, most of my country's oilfields have entered a period of medium and high water cut. The water content in the produced fluid of oil wells has increased sharply, and the amount of oily wastewater in the oilfield has also increased correspondingly. With the development and production of offshore and offshore oilfields and the need for environmental protection, higher requirements are put forward for oil-water separation. Due to the space limitation of the offshore oil production...
