Abstract

A composite oil remover is a horizontal cylindrical container which reduces the oil content in sewage to less than 50mg/L from less than 1000mg/L. The oil remover consists of a horizontal steel-made cylindrical contained and a vortex separator arranged on the top of the container. The interior of the cylinder body is provided with two stages of lipophilic coalescence fillers and a set of slant boards. Coming water enters the vortex separator first to remove the majority of the contained oil, and then enters the cylindrical container to remove the residual oil in the oil-containing sewage after successively passing through each filler stage. Flocculants are thrown in at the outlet of the vortex separator with a dosage of less than or equal to 100mg/L. The detailed structure is shown in the attached drawing.

Description

The combined oil removing device

The utility model relates to a kind of oil field oily(waste)water oil eliminator, is applicable to that handling oil water-mass density difference is greater than 0.05g/cm ³Oily(waste)water.

The widely used oily(waste)water oleaginousness that makes has three kinds by the method that 1000mg/L reduces to below the 50mg/L on the oil field at present, and the one, hydrocyclone oil removing, the 2nd, big jar oil removing, the 3rd, swash plate oil removing.Though hydrocyclone oil removing treatment capacity is bigger, pressure reduction is bigger, and general pressure drop is greater than 0.2Mpa; Though the two kinds of deoiling method pressure drops in back are less, but consumption of chemical agent is 200～400mg/L nearly, for addressing this problem, common way is that branch is handled oily(waste)water for several sections, though technical indicator can reach requirement, consumption of chemical agent also can be reduced to about 100mg/L, has the technical process complexity, construction investment is higher, the problem that the maintenance management workload is bigger.

The purpose of this utility model is that a kind of improved combined oil removing device will be provided, and it can make sewage with oil be reduced to below the 50mg/L by 1000mg/L, and pressure drop only is 0.1Mpa, can also make consumption of chemical agent be lower than 100mg/L.

The purpose of this utility model is achieved in that the combined oil removing device is made up of a horizontal steel cylindrical vessel and a vertical swirler, and swirler utilizes the pressure drop of 0.1Mpa that sewage with oil is reduced to about 100mg/L by 1000mg/L; The oil eliminator main part makes sewage with oil be reduced to below the 50mg/L by 100mg/L in 15 minutes time of oily(waste)water stop.

The utility model suitably reduces the length of cyclone pipe small cone section, increases the internal diameter of small cone section, and pressure drop is controlled in the 0.1Mpa, and oil-containing is reduced to below the 100mg/L by 1000mg/L; The coalescent pack of secondary lipophilic is set in the oil eliminator main body and one group of swash plate is used to make sewage with oil to reduce to below the 50mg/L from 100mg/L, the chemical agent spin current device bottom of playing throwing out adds in the low oily(waste)water, rather than chemical agent joins oil-containing and reaches in the sewage of 1000mg/L as common sedimentation removes oil tank, therefore can reduce the consumption of chemical agent significantly.

The concrete structure of utility model is provided by Fig. 1.

Describe the details and the working process of the combined oil removing device that the utility model proposes in detail below in conjunction with Fig. 1.

The sewage of oil-containing 1000mg/L enters swirler (8) from inlet (1), and tangentially enter swirler, the effusive oil of swirler enters oil header through communicating pipe (7), the sewage that oil-containing is lower than 100mg/L enters horizontal container (16) through aqueduct (12), sewage is after entering swash plate group (11) oil removing after the firsts and seconds lipophilic coalescent pack (9) (10), enter hydroecium (13) through aqueduct (6), flow out oil eliminator through water outlet (4).The isolating oil of oil eliminator flows into grease chamber (14) with the isolated oil of swirler and flows out oil eliminator through oil export (5).Flocculation agent adds from dosing mouth (2), and fluid level transmitter mouth (3) is arranged on the hydroecium middle part.Aqueduct (6) upper end that is provided with in the hydroecium (13) is equipped with water-oil interface setter (15), by the liquid level difference of its adjustable fuel-economizing hydroecium, thereby guarantees the stable of the interior water-oil interface of horizontal container, makes oily water separation reach design objective.

Claims (2)

1, a kind of horizontal oil eliminator is made up of steel Horizontal Cylindrical Tank and a degreaser cyclone installing above, it is characterized in that the oil outlet pipe of the isolated oil of swirler by top enters the oil trap in the horizontal container; Be provided with the coalescent pack of secondary lipophilic and one group of swash plate in the horizontal container; Be provided with grease chamber and hydroecium in the horizontal container, the grease chamber links to each other with the aqueduct of hydroecium by the bottom, is provided with liquor-level regulator in the hydroecium.

2, oil eliminator according to claim 1 is characterized in that the water-oil interface setter system in the hydroecium constitutes by one section moving casing of increase and corresponding regulating mechanism on aqueduct.
