Technical field
The utility model relates to a kind of deposition dehydrating device in crude oil dehydration field, particularly a kind of refiltered oil deposition dehydrating device.
Background technology
Along with the use of tertiary oil production in oil field technology, the crude oil that major part is exploited out is existed with form of emulsion, and emulsification is serious.Water-oil emulsion in the equipment such as sewage precipitation tank, at certain condition and stable gradually in the time, forms ageing oil, along with the prolongation of time, forms certain thickness, and the existence of ageing oil has brought series of problems to normal production the in oil field.Refiltered oil milk sap complicated component, contains the mechanical impuritys such as clay that much electroconductibility is stronger and FeS, often can cause dewatering system self-cleaning oil moisture exceed standard or de-after sewage quality exceed standard.Meanwhile, because the electroconductibility of these impurity is stronger, tend to cause apparatus for electrodewatering to occur Frequent trip, the electric field that even collapses, causes dewatering electric field operation not steady.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the problem that the dewatering system operation existing in background technology is not steady and deviate from poor water mass, and provide a kind of refiltered oil deposition dehydrating device, this refiltered oil deposition dehydrating device, can improve the running stability of dewatering system, effectively improve and deviate from quality.
The invention for solving the technical problem can reach by following technical solution: this refiltered oil deposition dehydrating device, comprise tank body, described center, tank body one end has fluid inlet, fluid inlet connects horizontal feed liquor pipeline, described feed liquor pipeline connects the cloth liquid case in the relative side tank body of fluid inlet, in tank body, by the first coalescent pack section and the second coalescent pack section, inner chamber is divided into San Ge district from left to right, be respectively feed liquor district, the first disengaging zone, the second disengaging zone, described cloth liquid case is in feed liquor district, the second disengaging zone tank body right-hand member is respectively arranged with grease chamber up and down, hydroecium, described grease chamber, hydroecium have oil outlet, water outlet.
The utility model is compared and can be had following beneficial effect with above-mentioned background technology: this refiltered oil deposition dehydrating device, owing to adopting said structure, improves the running stability of dewatering system, has effectively improved and has deviate from quality.Apply this device processes refiltered oil, adding emulsion splitter 100mg/L, 70 ℃ of left and right for the treatment of temp, under the condition of residence time 6h, can reach de-rear oily water ratio below 0.5%.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-cloth liquid case, 2-tank body, 3-the first coalescent pack section, 4-light hole A, 5-the second coalescent pack section, 6-light hole B, 7-detector for oil-water interface table mouth, 8-venting port, 9-oil outlet, 10-fluid inlet, 11-water outlet, 12-grease chamber, 13-hydroecium, 14-sewage draining exit A, 15-feed liquor pipeline, 16-sewage draining exit B.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this refiltered oil deposition dehydrating device comprises tank body 2, described tank body 2 centers, one end have fluid inlet 10, fluid inlet 10 connects horizontal feed liquor pipeline 15, the cloth liquid case 1 that feed liquor pipeline 15 connects in the relative side tank body of fluid inlet, in tank body 2, by the first coalescent pack section 3 and the second coalescent pack section 5, inner chamber is divided into San Ge district from left to right, be respectively feed liquor district, the first disengaging zone, the second disengaging zone, described cloth liquid case 1 is in feed liquor district, the second disengaging zone tank body right-hand member is respectively arranged with grease chamber 12 up and down, hydroecium 13, on the first described disengaging zone tank body, have light hole A4, sewage draining exit A14, on the second disengaging zone tank body, have light hole B 6, sewage draining exit B16, detector for oil-water interface table mouth 7, venting port 8, described grease chamber 12, hydroecium 13 have oil outlet 9, water outlet 11.
This refiltered oil deposition dehydrating device, refiltered oil enters from one end of device through feed liquor pipeline 15 by fluid inlet 10, the end of feed liquor pipeline arranges Novel cloth liquid case 1, box type cloth liquid case not only has good current stabilization rectification characteristic, simultaneously liquid at this through water washing process, be conducive to breakdown of emulsion, there is certain pre-separation effect.Liquid, through 3 rectifications of the first packing section and coalescence effect, comes liquid flow velocity trend after rectification even, and the kinestate of liquid stream is adjusted, liquid stream is evenly distributed, constant speed is advanced, and is conducive to liquid layered, has reduced due to the inhomogeneous impact causing on oil-water separation of liquid stream.Second segment knot filler poly-5 coalescence effects, the effectively dewatering efficiency of ageing oil settling separation device.For the ease of the cleaning of coalescent pack, the top every section of coalescent pack, is provided with breather hole, plays the effect of ventilation and printing opacity during maintenance.Produced Liquid after layering, oil reservoir enters grease chamber 12, through oil outlet 9, flows out, and low oily(waste)water enters hydroecium 13, through water outlet 11, flows out.
Apply this device processes refiltered oil, add emulsion splitter 100mg/L in feed liquor pipeline, 70 ℃ of left and right for the treatment of temp, under the condition of residence time 6h, can reach de-rear oily water ratio below 0.5%, reach the moisture index request of outer oil transportation.
This refiltered oil deposition dehydrating device, fluid inlet arranges box type sparger, and box type not only has good current stabilization rectification characteristic, liquid, at this through water washing process, is conducive to breakdown of emulsion simultaneously, has certain pre-separation effect, simple in structure, be easy to install, be suitable for applying in engineering.Consider that refiltered oil content of impurities is high, easily make conventional coalescent pack stop up, settling section is arranged two sections of renewable ceramic packings of being convenient to cleaning, utilizes the water-wet behavior of ceramic packing, and what be conducive to that W/O drips is coalescent.First paragraph filler plays rectifying action, comes liquid flow velocity trend after rectification even, and the kinestate of liquid stream is adjusted, and liquid stream is evenly distributed, and constant speed is advanced, and is conducive to liquid layered, has reduced due to the inhomogeneous impact causing on oil-water separation of liquid stream.Second segment filler plays coalescence effect, effectively the dewatering efficiency of ageing oil settling separation device.In oil, water chamber structure, oil export baffle plate adopts ramp type, and the destruction of sloping baffle stream field stable uniformity is less.Adopt less grease chamber, increase water settling volume, and then improve the processing power of equipment.Before water outlet, set up sand control baffle plate, be convenient to sand removal sand control simultaneously.
