As shown in Figure 1, the utility model embodiment provides a kind of filter, and it may include: shell 1, it is internal empty
Between be divided into straining chamber 101 and the refined filtration room 102 above straining chamber 101, straining chamber 101 is connected with refined filtration room 102,
It is equipped with modified fiber ball in straining chamber 101, sintering metal powder filter element is equipped in refined filtration room 102, is set on the side wall of shell 1
It is equipped with the water inlet 103 being connected with straining chamber 101 and the water outlet being connected with refined filtration room 102 104, thus refined filtration room
102 are located at the downstream of straining chamber 101 along water (flow) direction.
In the present embodiment, shell 1 can select diameter Ф 140mm, and the steel pipe of length 500mm is made, and the upper end is under
End is open, and can in top and bottom, removably connection cover closes the upper of end opening and lower ending opening respectively
End cap 2 and lower cover 3.
Upper end cover 2 is identical with the structure of lower cover 3, can select diameter Ф 180mm, the carbon steel of length 120mm
At, and be threadedly coupled with shell 1.Upper end cover 2 and lower cover 3 are designed to the mode being detachably connected with shell 1, can be convenient
The sintering metal powder filter element of modified fiber ball and refined filtration room 102 in straining chamber 101 is replaced.
The center of upper end cover 2 and lower cover 3 be respectively arranged with Ф 30mm upper installing hole 4 and lower mounting hole 5, and exist respectively
The purge valve 9 being connected with refined filtration room 102 and the row being connected with straining chamber 101 dirt are set in upper installing hole 4 and lower mounting hole 5
Valve 10.
Further, lateral partition 6 can be set in shell 1, be provided with through-hole on partition 6 to realize straining chamber
101 are connected to refined filtration room 102, so that the inner space of shell 1 is separated into straining chamber 101 and refined filtration room 102 by partition 6.
In addition, the outer wall of shell 1 can be respectively arranged with the water supply connector 7 being connected with water inlet 103 and water outlet 104
With water outlet connector 8, water supply connector 7 with back with water inlet line for being connected, and water outlet connector 8 with waterflood-transmission line for being connected.Water inlet

The filter of the utility model embodiment, by accommodating modified fiber ball in straining chamber 101 as level-one filter core,
Sintering metal powder filter element is accommodated in refined filtration room 102 as second level filter core.Modified fiber ball pollutant carrying capacity is strong, can will be into
The sewage for entering refined filtration room 102 is pre-processed, its suspension content is reduced, and extends the service life of filter, reduces backwash work
It measures；Sintering metal powder filter element can make further filtering by pretreated sewage to modified fiber ball, thus into one
Step reduces suspended matter therein and iron-content, avoids in reinjected water and causes because above-mentioned substance is excessive to subsequent water injection work
Adverse effect.
In the present embodiment, the sintering metal powder filter element as second level filter core is the key link of filter, if come
Suspension content is excessively high in water, and sintering metal powder filter element water amount will be made to reduce quickly, loses filtration, increases backwash
Workload.Therefore, straining chamber 101 is set in the water upstream of refined filtration room 102, and modified fiber ball is set in straining chamber 101
As level-one filter core, pollutant carrying capacity is stronger, and so as to pre-process the sewage for entering refined filtration room 102, it is outstanding to reduce it
Floating object content extends the service life of filter, reduces backwash workload.
All components of the filter of the utility model embodiment can be by 1.2 times of use site highest water injection pressure
Coefficient is designed production, it is ensured that the safe operation and service life of filter.
The filter of the utility model embodiment, each section component is since working face stress is little, as long as each position connects
Fastening, each component use common welding manner, are bolted assembling.
The course of work is: scene uses horizontal installation, and under certain pressure effect, sewage enters thick through water inlet 103
Filter chamber 101 retains most suspended substances in straining chamber 101, then the sintering metal powder filter element through refined filtration room 102 into
Row filtering, clear water is through in 104 note to well of water outlet after filtering.The filter core pollutant carrying capacity of straining chamber 101 is strong, and main function is exactly
The sewage for entering refined filtration room 102 is pre-processed, its suspension content is reduced, extends the service life of filter, is reduced anti-
Wash workload.Purge valve 9 and the dirty valve 10 of row are opened when backwash, the utility model, which is discharged, by the dirty valve of row in the impurity being filtered off implements
The filter of example is easy for installation, and end weldering connection uses φ 50mm welding groove.Do not have to filter of dismantling when replacing filter core, works as filter
When core is blocked by dirt, need to only dismantle end cap 3 up and down then be can be taken off, and end cap 3 up and down is tightened by spare filter element replacing, after replacement and is
It can.
Compared with existing well filter, the effect of the filter of the utility model embodiment has:
1, hydrophilic and oleophobic, backwash easily regenerate, and are particularly suitable for filtering oilfield sewage；
2, filtering velocity is high, is 3~4 times of sand filtration filtering velocity；
3, pollutant carrying capacity is strong, is 2~4 times of quartzy sand filter blanket；
4, backwash water is few, is the half of sand filtration backwash water；
5, have the characteristics that corrosion-resistant, high-intensitive, filtering accuracy is high；
6, filter uses secondary filtration, expands application range, ensure that filtering accuracy, small in size, structure is compact, more
Filter core is changed to be easy, is easy to install and use.
Through field test, the filter effect of the utility model embodiment clearly, oil-containing, iron content, suspended matter, partial size
Intermediate value is all strictly controlled, water after filter index: oil content≤2mg/L, suspension content≤1mg/L, median particle size≤2 μm,
Fully meet the requirement of low permeability pay water filling.
Spot effect also indicates that the filter of the utility model embodiment meets construction requirement, compact-sized, volume
It is small, convenient for operation, guarantee construction safety, promotional value is significant.
It should be understood that above description is to illustrate rather than to be limited.By reading above-mentioned retouch
It states, many embodiments and many applications except provided example all will be apparent for a person skilled in the art
's.Therefore, the range of this introduction should not be determined referring to foregoing description, but should referring to preceding claims and these
