Detailed Description
The oil-gas separation device of the present invention is further described with reference to the accompanying drawings and examples:
referring to fig. 1 and 2, an oil-gas separation device includes a housing 1 with two open ends, i.e., an inlet end and an outlet end.
Be provided with adjustable fender 4 in casing 1, adjustable fender 4's external diameter is greater than the open diameter of inlet end, and adjustable fender 4 is the adjustable fender of hollow spherical crown shape, and the open end of adjustable fender 4 is towards the inlet end. The flapper 4 is preferably a flapper of aluminum alloy.
Be provided with on casing 1 inner wall and be used for carrying on spacing protruding 5 to adjustable fender 4, adjustable fender 4 is located between spacing protruding 5 and the inlet end. The stop protrusion 5 is preferably a cylindrical stop protrusion.
The limiting protrusion 5 is an inclined limiting protrusion, and the limiting protrusion 5 is preferably inclined towards the air outlet end. When adjustable fender 4 floated under the effect of the air current of oil-gas mixture, the air current flowed from adjustable fender 4's edge, because adjustable fender 4 is the spherical crown shape, at this moment, spacing arch 5 was the spacing arch of slope too to spacing arch 5 inclines towards the end of giving vent to anger, the smooth and easy outflow of the air current of being convenient for like this.
Preferably, six limiting protrusions 5 are uniformly distributed along the inner wall of the shell.
Still fixed being provided with fixed stop 6 on casing 1 inner wall, fixed stop 6 sets up between spacing arch 5 and the end of giving vent to anger.
The fixed baffle 6 is preferably a conical fixed baffle with two open ends, the large diameter end of the fixed baffle 6 is close to the air inlet end, and the small diameter end of the fixed baffle 6 is close to the air outlet end.
