Description

A kind of compact type suspended substance floatation equipment
Technical field
The utility model relates to suspended substance treatment facility, and be specially oily(waste)water suspended substance separating device in a kind of oil-gas field profit treating processes, it effectively can be separated the suspended substance in oily(waste)water, for the advanced treatment of oily(waste)water reduces suspended substance processing load.
Background technology
At present, the suspended substance process in Domestic Oil And Gas Fields production waste treating processes mainly relies on filter separator to be separated, and its advantage is that suspended substance treatment effect is obvious; But its equipment filter element replacing is frequent, require that the later stage continues investment, and its equipment filter core specification directly determines suspended substance separating effect.
Owing to the addition of various chemical reagent in production of hydrocarbons process, as inhibiter, emulsion splitter, water cleaning agent etc., make the suspended substance existence in production waste complicated.Its principal feature shows as, and suspended substance surface attachment has oil film; After the enrichment of oil (suspended substance) phase leaves standstill, sedimentation of suspension is bottom oil phase.
Summary of the invention
The purpose of this utility model is as oil-gas field oil-containing production waste advanced treatment provides a kind of compact type suspended substance floatation equipment.
The technical solution adopted in the utility model is: a kind of compact type suspended substance floatation equipment, comprises low flow field swirling flow unit, swirl element, oil-collecting (suspended substance) chamber, collection production waste chamber and gravity settling post; Two symmetrical tangential production waste imports are provided with bottom the swirling flow unit of low flow field, inside is provided with the eddy flow guide card guiding production waste to produce eddy flow, top outer tube inner wall is provided with production waste bypass outlet, inner tank theca is provided with oil-containing (suspended substance) sewage outlet and is communicated with swirl element by pipeline, and its top gas phase district is provided with pressure relief vent; Swirl element inside is provided with coaxial eddy flow guide card, export primarily of main cyclone section, with one heart undergauge section, thin conical section, production waste outlet and sump oil (suspended substance) and form, wherein production waste outlet communicates with collection production waste chamber, and sump oil (suspended substance) outlet communicates with oil-collecting (suspended substance) chamber; Collection is provided with sand export bottom production waste chamber, and top communicates with gravity settling post; Be provided with sump oil (suspended substance) outlet bottom oil-collecting (suspended substance) chamber, be connected to outer drum outer wall by pipeline; Gravity settling column top is provided with production waste outlet, is connected to outer drum outer wall by pipeline.
Low flow field swirling flow unit in the utility model, two tangential symmetrical production waste imports, the axial symmetry of production waste eddy flow between urceolus and inner core can be ensured, eddy flow guide card can make production waste produce eddy flow, because in production waste, oil (suspended substance) water-mass density is different, under the influence of centrifugal force, aqueous phase to urceolus direction spiral, oil (suspended substance) inner core direction spiral in opposite directions; Oil-containing (suspended substance) sewage aqueous phase after swirl element enters collection production waste chamber, then in gravity settling post, heavy impurity is deposited in collection production waste chamber through sedimentation, heavy impurity is discharged by sand export, production waste is exported by production waste and discharges, oil (suspended substance) enters oil-collecting (suspended substance) chamber mutually, exports discharge through pipeline by sump oil (suspended substance).
The utility model has the advantage of and the gravity settlement process eddy flow centrifugation of suspended substance is substituted, through twice cyclonic separation, improve the separating effect of oil (suspended substance) phase, simultaneously, production waste is through gravity settling post, and heavy impurity is able to effective deposition; Compare filtering type suspended substance separating device, the utility model can not only carry out flotation to suspended substance, and can carry out oily water separation, add equipment function, make equipment more compact, simultaneously, device structure is simple, is convenient to manufacture processing, is easy to promote the use of.
Accompanying drawing explanation
Fig. 1 is the textural association schematic diagram of a kind of compact type suspended substance of the utility model floatation equipment.
Embodiment
As shown in Figure 1, a kind of compact type suspended substance of the utility model floatation equipment, comprises low flow field swirling flow unit (9), swirl element (7), oil-collecting (suspended substance) chamber (1), collection production waste chamber (12) and gravity settling post (2).Wherein, low flow field swirling flow unit (9) forms with production waste bypass outlet primarily of production waste import (10 or 20), eddy flow guide card (11), oil-containing (suspended substance) sewage outlet (19); Swirl element (7) exports (8) with production waste form primarily of main cyclone chamber (15), with one heart undergauge section (5), thin conical section (6), sump oil (suspended substance) outlet (3).
As shown in Figure 1, after production waste enters low flow field swirling flow unit (9), by production control wastewater inlet discharge capacity (10 or 20) and production waste bypass outlet (4) discharge capacity, low flow field swirling flow unit (9) and gas phase zone (14) is made to form malleation, after ensureing that oil-containing (suspended substance) sewage enters swirl element (7), under the eddy flow of eddy flow guide card guides, oil (suspended substance) water can be made to carry out abundant cyclonic separation.Wherein, the main cyclone chamber (15) of swirl element (7), with one heart undergauge section (5) and thin conical section (6) inwall are provided with coaxial spiral eddy flow guide card, and can ensure that the envelope curve that arbitrary section is formed by eddy flow guide card outer rim for the vertical of thin conical section (6) spiral flow guide card and axial direction due is hollow; Oil-containing (suspended substance) sewage in concentric undergauge section (5) and thin conical section (6) because swirl element (7) diameter of section reduces and vertical action of gravity, oil-containing (suspended substance) sullage rotational flow speed is accelerated, form action effect back pressure upwards on concentric undergauge section (5) top, be conducive to the cyclonic separation of oil (suspended substance) water; Gravity settling post (2) is the inner column structure in cavity, and after production waste enters its inside, heavy impurity, under current carry the acting in conjunction such as power, gravity, carries out gravity settling, and its entrance production waste discharge capacity and its cross section directly determine effect of settling.
Principle of work and the process of a kind of compact type suspended substance of the utility model floatation equipment are: the two-phase fluid under certain pressure condition, under the guiding of eddy flow guide card, form eddy flow, produce centrifugation and then alternative gravity fractionation, reach two-phase initial gross separation; Light fluid enters swirl element and carries out degree of depth cyclonic separation, reaches two-phase laminated flow effect, and wherein, the light component in light fluid is discharged after liquid collecting cavity collects, and heavy component is discharged after gravity settling post is separated again; And after heavy fluid backflow discharge, carry out circular treatment again.
