Description

A kind of new oil water separation device
Technical field
The utility model relates to a kind of oily-water seperating equipment, particularly a kind of with air-water the oily-water seperating equipment in conjunction with backwash.
Background technology
Oil extraction-generated waste water claims again oil field extracted water, and these sewage are after processing is up to standard, and a part is as the re-injection water of secondary oil recovery, and another part discharges; At present, the oil extraction-generated waste water in oil field mainly adopts the dark bed of quartz sand, nut-shell or fibrous nodules filtering material filter to process; Stablizing and maintaining of deep-bed filter media performance relies on back flushing to be achieved; Common backwash mode be air-water in conjunction with back flushing, can effectively clean dirt on filtrate by the effect of G&W; But the power consumption that prior art is used is high, air blasting intensity is large, causes equipment volume excessive, and filtrate cleaning performance is not good, and scavenging period is long.
Summary of the invention
For fear of the shortcoming and defect part existing in above-mentioned technology, the purpose of this utility model is to design a kind of new oil water separation device, not only can reduction equipment volume, and the oily-water seperating equipment low, that air blasting intensity is little, cleaning performance good, scavenging period is short that consumes energy.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of new oil water separation device, comprises a two medium filter device; Described two medium filter devices are made up of cylindrical shell, import pipe fitting, exhaust pipe fitting, water-distributing device, filtrate, washing component, air purge assembly, screen, captation and outlet pipe fitting; Described cylindrical shell respectively with import pipe fitting, exhaust pipe fitting, water-distributing device, washing component, air purge assembly, screen, captation and outlet pipe fitting welding; Described filtrate is laid on screen; Described air purge assembly also comprises cleaning core pipe, gas ejector pipe and pipe collar; Described cleaning core pipe is fixedly welded on cylindrical shell by pipe collar, and described gas ejector pipe is connected to and cleans core pipe inside center place, is welded on air purge assembly supervisor; Described air purge assembly annular arrangement is in filtrate.
Compared with prior art, the utlity model has following beneficial effect:
1, the air-water that the utility model adopts is simple in structure in conjunction with back washing device, and volume is little, lightweight, air blasting intensity is little, cleaning performance good, scavenging period is short; Therefore, described plant energy consumption is low, and maintenance time is short, and working efficiency is high;
2, two medium filter devices that the utility model adopts, double medium filtration, the raising scrubbing effect of deoiling.
Accompanying drawing explanation
Describe the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is two medium filter schematic diagram.
Fig. 2 is that the two medium filter A-A of Fig. 1 are to sectional view.
Fig. 3 is two medium filter air purge unit construction schematic diagram.
In figure: 1, cylindrical shell, 2, import pipe fitting, 3, exhaust pipe fitting, 4, water-distributing device, 5, filtrate, 6, washing component, 7, air purge assembly, 8, screen, 9, captation, 10, outlet pipe fitting, 11, clean core pipe, 12, gas ejector pipe, 13, pipe collar, 14, air purge assembly supervisor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of new oil water separation device, comprises a two medium filter device; Described two medium filter devices are made up of cylindrical shell 1, import pipe fitting, exhaust pipe fitting 3, water-distributing device 4, filtrate 5, washing component 6, air purge assembly 7, screen 8, captation 9 and outlet pipe fitting 10; Described cylindrical shell 1 welds with import pipe fitting 2, exhaust pipe fitting 3, water-distributing device 4, washing component 6, air purge assembly 7, screen 8, captation 9 and outlet pipe fitting 10 respectively; Described filtrate 5 is laid on screen 8; Described air purge assembly 7 also comprises cleaning core pipe 11, gas ejector pipe 12 and pipe collar 13; Described cleaning core pipe 11 is fixedly welded on cylindrical shell 1 by pipe collar 13, and described gas ejector pipe 12 is connected to and cleans core pipe 11 inside center places, is welded on air purge assembly supervisor 14; Described air purge assembly 7 annular arrangements are in filtrate 5.
Shown in Fig. 1 and 3, working routine of the present utility model is as follows:
Oil extraction-generated waste water enters into water-distributing device 3 from two medium filter import pipe fittings 2, evenly be sprinkled upon on filtrate 5 by water-distributing device 3, by filtrate 5, absorption greasy dirt and suspended substance wherein, make oily water separation, the water that reaches emission standard is discharged into next unit from two medium filter outlet pipe fittings 10; When filtering after for some time, reach the pressure reduction of setting, system stops filtering, and enters into the backwash stage; Backwash water enters washing component 6, and air enters air purge assembly 7 simultaneously; In conjunction with cleaning, remove greasy dirt and suspended substance in filtrate 5 by air-water, backwash sewage and backwash gas are discharged from two medium filter outlet pipe fittings 10 and venting port 3, and detailed process is as follows:
1, positive washing procedure: open the valve of two medium filter import pipe fittings 2 and outlet pipe fitting 10, after effluent quality reaches standard, enter the normal filtration stage;
2, filter: when strainer moves under normal filtration state, should open draining valve and the vent valve on exhaust pipe fitting 3 at interval of for some time, oil slick and the gas assembled to get rid of filter tank top; After operation for some time, arrive and set pressure reduction, enter the backwash stage;
The backwash stage: at air-water during in conjunction with backwash, open the valve of air purge assembly 7, gas is evenly ejected on filtrate 5 by gas ejector pipe 12, make filtrate 5 increase along cleaning core pipe 11, open the valve of washing component simultaneously, water rinses filtrate 5 bottoms by washing component 6, makes filtrate 5 form cyclic motion under the effect of G&W, reaches the object that filtrate 5 all cleans up.
