Technical field
The utility model relates to the waste disposal plant technical field, relates in particular to a kind of self-adaptation oilfield sewage treatment device.
Background technology
At present, oilfield exploitation adopts water flooding recovery more, its water source and surface water and groundwater, and extraction Water in oil rate is high, needs to dewater through dehydrating station.Deviating from water, to show as the water yield large, heavy metal element is many, oleaginousness, salinity, COD(chemical oxygen demand (COD), refer under certain strict condition, the reducing substances in the water under the effect of the strong oxidizer that adds, the quantity of the oxygenant that consumes during oxidized the decomposition, mg/L with oxygen represents), SS(suspend solid, suspended solid) content is high, directly effluxes not only contaminate environment, and heavy metal element can cause serious harm to underground water source; And also be a kind of waste, take a kind of appropriate treatment process, make the water main road waterflooding requirement after the processing, be used for the oil field re-injection, realize the sustainable use of water, saving water resource.
The treatment process of prior art mainly is to rely on gravity separation, media filtration to finish sewage disposal, and its shortcoming is exactly the device structure complexity, and technical process is long, and cost of use is high, and processing accuracy is low.
The utility model content
The purpose of this utility model provides a kind of simple in structure, technical process is short, cost of use is low, processing accuracy is high a kind of self-adaptation oilfield sewage treatment device.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of self-adaptation oilfield sewage treatment device, comprise the first lift pump, the second lift pump, the 3rd lift pump, directed cyclone purifier, shunting separator, film filter, described the first lift pump connects directed cyclone purifier, described directed cyclone purifier connects the second lift pump, described the second lift pump connects the advection separator, described advection separator connects the 3rd lift pump, described the 3rd lift pump junctional membrane strainer, water injection tank is removed in described film filter connection.
The beneficial effects of the utility model are: the utility model adopts three grades of flow processs, water pot in the middle of saving, and simple in structure, technical process is short, and cost of use is low.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described film filter is the sintered stainless steel metal film filter.Adopt the beneficial effect of above-mentioned further scheme to be: the high-strength stainless steel multi-layer sintering, high temperature resistant, anti-strong acid, anti-highly basic, by the metallic membrane pressure filter of special process design, filtering accuracy is high, has eradicated 2～4 hours underproof problems of water outlet behind the system backwash.
Further, in the described sintered stainless steel metal film filter four sintered stainless steel metallic membranes are arranged.
Adopt the beneficial effect of above-mentioned further scheme to be: to adopt the multi-metal film, filter more effective.
Further, the shell of described sintered stainless steel metal film filter is carbon steel.
Description of drawings
Fig. 1 is structure iron of the present utility model;
Fig. 2 is the structure iron of sintered stainless steel metal film filter.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, directed cyclone purifier, 2 advection separators, 3, film filter, 4, remove water injection tank, the 5, first lift pump, the 6, second lift pump, the 7, the 3rd lift pump, 8, the sintered stainless steel metallic membrane, 9, the strainer water-in, 10, the strainer water outlet.
Embodiment
Sewage is by adding the nanometer conditioning agent the oil in the sewage, suspended particle, the oil in water emulsion mixture adsorbs, then add flocculation agent, the floc sedimentation of the impurity absorption in the sewage being formed bulk, then adding coagulant aids increases the weight of flco, will be through the reinforced sewage lifting of processing to directed cyclone purifier 1 by the first lift pump 5, because the special tectonic of directed cyclone purifier 1 tank body, make sewage in entering the process of tank body according to predetermined direction eddy flow, sewage enters reaction cabin, sewage forms resonance in the cabin, it is moving to form strong wadding, makes the effect of medicament perform to ultimate attainment in the cabin, under eddy flow, realize sharp separation, and the water exit position of reaction cabin is set according to the water yield, through repetition test, has determined best water exit position, oil, suspended substance and moisture are from rear, current rise, and mud descends, and clear water is from tank body top water outlet, the equipment top is provided with oil recovery appts., regularly discharges by pipeline.
The second lift pump 6 will be from directed cyclone purifier 1 sewage lifting out to advection separator 2, and sewage is by adding coagulant aids, cyclone separator is come the contained micro-sewage with oil of water and the suspended substance removal close with the density of water under the advection state.Tank design in the tank is adopted in the inside of advection separator 2, the internal structure of annular makes the settling time longer, the suspended substance removal close with water-mass density in the sewage, the water distribution system of advection separator 2 inside makes sewage, and the water flows gently, coming in the situation of water unstable, can add water quality stabilizer etc. and process, guarantee that the water that enters fine filtering reaches the A3 grade standard.And water pot in the middle of saving.
In the present embodiment, film filter 3 is the sintered stainless steel metal film filter, under the effect of the 3rd lift pump 7, to be promoted to the sintered stainless steel metal film filter by strainer water-in 9 from advection separator 2 sewage out, sintered stainless steel metallic membrane 8, high temperature resistant, anti-strong acid, anti-highly basic, aperture on the sintered stainless steel metallic membrane 8 can be determined by effluent quality as required, be used for fine filtering, sintered stainless steel metallic membrane 8 has special type filler, adds sterilant and Scale inhibitors, guarantees water conditioning, do not stop up after the water filling, filter index according to on-the-spot needs design, reach the above standard of A1 level from strainer water outlet 10 water outlet out, do not establish the back flushing unit, equipment is more shock-resistant, and is easy and simple to handle.
Enter the water injection tank 4 from strainer water outlet 10 water out, finish the processing of sewage.
