Description
Technical field
The invention belongs to oil field sewage treating equipment technical field, and in particular to a kind of oilfield sewage oil removal sand removal sedimentation dress
Put.
Background technology
Existing oil-bearing wastewater relies primarily on the oil removing of three-level settling tank, desanding, and sewage is set by water process after sedimentation
It is standby to filter injection oil reservoir up to standard.In general, sewage is entered directly into one-level settling tank, and sewage silt particle has little time to settle
Oil removing, suspended oil can mix with sewage again, carry greasy dirt and silt particle sewage and sequentially enter two level sedimentation, three-level by inclined hole
Settling tank, sedimentation oil removing effect is so not only unable to reach, three-level settling tank can be also caused by sewage pollution, largely containing greasy dirt
After water enters water treatment facilities, sludge and oil emulsion are enriched in fine filtration device surface (fibrous nodules or sintered pipes), can damage
Bad fine filtering apparatus, cause serious economic loss.
The cleaning cycle length of oilfield sewage, cleaning work amount is big, and settling supporting air-float degreasing device according to big tank is carried out
Sewage disposal, fund input can be bigger, are not suitable for the actual production in some oil fields, therefore to the oil removing settling of oilfield sewage
Pond carries out transformation and is significant.
The content of the invention
It is an object of the invention to provide a kind of oilfield sewage oil removal sand removal sedimentation device, oilfield sewage can be carried out effective
Oil removing, desanding processing.
The technical solution adopted in the present invention is a kind of oilfield sewage oil removal sand removal sedimentation device, including set gradually
Sluicing pond, buffer pool, one-level settling tank and two level settling tank, sluicing pond are connected by the first screen casing with buffer pool, and buffer pool leads to
Cross the second screen casing to be connected with one-level settling tank, one-level settling tank is connected by the 3rd screen casing with two level settling tank.
The features of the present invention also resides in：
The bottom in sluicing pond is provided with fin, and the bottom in sluicing pond is inclined to set.
The top of buffer pool is circumscribed with oil sump by the first oil collecting pipe；The top of two level settling tank passes through the second oil collecting pipe
Also it is connected with oil sump.
Valve is provided with first oil collecting pipe and the second oil collecting pipe.
The bottom of two level settling tank is provided with Ji Shachi, and collection sand is provided with sludge lifting pump in pond, and sludge lifting pump passes through
Pipeline is connected to outside two level settling tank.
The beneficial effects of the invention are as follows：
1. be provided with fin letting out basin bottom, fin can play a part of buffering waterpower, and the silt particle particle in sewage can quilt
Fin stops, so as in natural subsidence to sluicing pond, play a part of preliminary desanding；
2. sewage, after buffer pool, its power can further weaken, make sewage that there is enough sedimentation times, greasy dirt drift
Float over one layer of the top and be discharged to by the first oil collecting pipe in oil sump, meanwhile, sediment settlement is in buffer pool bottom, so that significantly
Reduce the content of dirty impurities in water, oil slick and silt particle；
3. screen casing is respectively equipped with sluicing pond, buffer pool, one-level settling tank and two level settling tank, when sewage enters down
During one-level sedimentation device, sewage is changed into sprinkling state from DC state, so as to play a part of Accelerated subsidence.
Brief description of the drawings
Fig. 1 is a kind of structural representation of oilfield sewage oil removal sand removal sedimentation device of the present invention.
In figure, 1. sluicing ponds, 2. buffer pools, 3. one-level settling tanks, 4. two level settling tanks, 5. fins, 6. first screen casings, 7.
First oil collecting pipe, 8. second oil collecting pipes, 9. oil sumps, 10. second screen casings, 11. the 3rd screen casings, 12. Ji Shachi, 13. sludge carry
Rise pump.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of structure of oilfield sewage oil removal sand removal sedimentation device of the present invention, as shown in figure 1, including the sluicing set gradually
Pond 1, buffer pool 2, one-level settling tank 3 and two level settling tank 4, sluicing pond 1 are connected by the first screen casing 6 with buffer pool 2, buffer pool
2 are connected by the second screen casing 10 with one-level settling tank 3, and one-level settling tank 3 is connected by the 3rd screen casing 11 with two level settling tank 4.
The bottom in sluicing pond 1 is provided with continuous fin 5, and the bottom in sluicing pond 1 is inclined to set.
The top of buffer pool 2 is circumscribed with oil sump 9 by the first oil collecting pipe 7, and the top of two level settling tank 4 passes through the second collection
Oil pipe 8 is also connected with oil sump 9.
Valve is provided with first oil collecting pipe 7 and the second oil collecting pipe 8.
The bottom of two level settling tank 4 is provided with collection sand pond 12, and sludge lifting pump 13, sludge lifting are provided with collection sand pond 12
Pump 13 is connected to outside two level settling tank 4 by pipeline.
A kind of oilfield sewage oil removal sand removal sedimentation device of the present invention, its concrete operating principle are：Oilfield sewage is introduced into
In sluicing pond 1, the bottom of sluicing pond 1 is provided with fin 5, and the bottom of sluicing pond 1 is inclined to set, and fin 5 reduces the buffering of sewage
Power, while under gravity, silt can be deposited in fin 5 along the bottom bevel of sluicing pond 1, play a part of preliminary desanding,
Sewage is entered in buffer pool 2 through the sprinkling of the first screen casing 6 afterwards, and buffer pool 2 further reduces the impulsive force of sewage, makes sewage
With enough sedimentation times, greasy dirt swims in above buffer pool 2 and is discharged to by the first oil collecting pipe 7 in oil sump 9, silt
The bottom of buffer pool 2 is deposited in, so as to further remove impurity, oil slick and the silt particle in decontaminated water, then sewage passes through second
The sprinkling of screen casing 10 is entered in one-level settling tank 3, and one-level settling tank 3 continues to carry out settlement treatment to sewage, and sewage leads to again afterwards
Cross the sprinkling of the 3rd screen casing 11 to enter in two settling tanks 4, the collection sand pond 12 of the sediment settlement in sewage to the bottom of two level settling tank 4
In, the silt in collection sand pond 12 is cleaned to outside two level settling tank 4 by sludge lifting pump 13, and the greasy dirt in two level settling tank 4 leads to
The second oil collecting pipe 8 is crossed to be discharged into oil sump 9.
Because the scale of one-level settling tank 3 and two level settling tank 4 is all bigger, thus sewage have in settling tank it is enough
Time is settled, and sewage is after one-level settling tank 3 and two level settling tank 4 settle, impurity therein, oil slick, silt content meeting
Greatly reduce, so as to reach water quality discharge standard.
