A kind of novel horizontal filters desander
Technical field
The utility model is related to a kind of novel horizontal filtering desander.
Background technology
Shale gas exploitation generally uses hydrofracturing method at present, need to be by a large amount of water mixing silt particles and small amount during exploitation
Learn in material injection well, the main component of silt particle is 30~100 mesh haydites, the haydite quantity is big, and hardness is high, individual well sand feeding amount compared with
Greatly, if this part haydite and silt particle not separated, serious erosion will be produced to the equipment in downstream and pipeline, therefore carry out
Effective desanding is most important.
Existing horizontal desander uses slit type screen casing, and media outlet is upward.The shale gas of aqueous and gravel is along Jie
Matter import enters desander, and depositing gravel is in screen casing, and liquid deposition is in equipment, medium and unsegregated gravel after filtering
To downstream line.Because slit type screen casing filtering accuracy is low, typically in 0.20mm or so, unsegregated gravel is arrived down by desander
When play pipe road and valve, pipeline and valve inwall can be washed away, causes the damage and the generation of accident of valve and pipeline.
Found according to field practice, existing desander has some following deficiency:
First, the media outlet of desander is upward, it is impossible to the liquid in remover apparatus, result in screen casing because liquid occurs to block up
Plug, not only reduces the precision and circulation area of screen casing, and also add the equipment sediment outflow frequency.
Second, the haydite that shale gas is used is general all between 0.10mm~0.50mm, using cutting seam sieve tube formula screen casing
Minimum filter diameter is 0.20mm, and diameter is less than 0.20mm gravel, and the screen casing can not be separated, low separation efficiency.
3rd, because liquid deposition is in device interior, when opening fast opening blind sediment outflow every time, have a large amount of liquid with gravel
Body is gushed, and causes environmental pollution.
4th, during handling screen casing, using Hard link, easily cause screen damage.
Utility model content
The utility model overcomes shortcoming of the prior art and filters desander there is provided a kind of novel horizontal.
The technical solution of the utility model is:A kind of novel horizontal filters desander, including horizontal cylinder and in horizontal cylinder
The back-roll weldering stainless steel screen casing set in vivo, sets medium entrance and fast opening blind, horizontal respectively at the two ends of horizontal cylinder
Down-set media outlet in the middle part of cylinder.
Further, flexible seal connecting mechanism is set between medium entrance and back-roll weldering stainless steel screen casing.
Further, it is provided with supporting guide between back-roll weldering stainless steel screen casing and horizontal cylinder.
Further, it is provided with compacting device between back-roll weldering stainless steel screen casing and fast opening blind.
Further, handle is set on back-roll weldering stainless steel screen casing.
Further, differential pressure transmitter is set respectively in medium entrance and media outlet.
Further, drain is set on horizontal cylinder top.
Further, saddle is set in horizontal cylinder bottom.
Further, the back-roll weldering stainless steel screen casing precision is 0.10mm.
Compared with prior art, the utility model has the advantages that:The frequency of sediment outflow is reduced, equipment is improved and uses effect
Rate;Improve desanding precision, reduce the damage to upstream device;Sediment outflow is convenient, reduces labor intensity;Screen casing facilitates installation to tear open
Unload and be hardly damaged.Specific manifestation is as follows:
1st, media outlet is arranged on housing central section downwards, due to the influence of Action of Gravity Field, and equipment medium outlet was then exhausted from
After filter while medium, take away the liquid of deposition, it is to avoid screen casing is blocked because of liquid, it is ensured that the precision of screen casing and circulation
Area, reduces the frequency of sediment outflow, improves equipment service efficiency.
2nd, desanding precision is improved, stainless steel screen casing is welded using back-roll, precision rises to 0.10mm.
3rd, avoid there are a large amount of liquid with gravel to gush when sediment outflow opens fast opening blind, cause environmental pollution, side
Sediment outflow operation, reduce labor intensity.
4th, using the seal form being easily attached between back-roll weldering stainless steel screen casing and sealing and connecting device and fast opening blind,
Ensure to be easy for installation and removal while sealing.More present slit type screen casing, it is ensured that the rigidity of screen casing and be not susceptible to brokenly
It is bad.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of novel horizontal filters desander, as shown in figure 1, including:Medium entrance 1, differential pressure transmitter 2, it is tightly connected
Device 3, end socket 4, equipment barrel 5, manual drain 6, back-roll weldering stainless steel screen casing 7, fast opening blind 8, saddle 9, media outlet
10th, differential pressure transmitter 11, guide rail 12 etc., wherein:
Medium entrance 1 and end socket 4 are set in the one end of novel horizontal filtering desander equipment barrel 5, set in the housing other end
Fast opening blind 8 is put, the down-set media outlet 10 of housing central section, enclosure interior sets sealing and connecting device 3 and guide rail 12 to be used for
Back-roll weldering stainless steel screen casing 7 is installed, positions and dismantled, and housing upper sets manual drain 6, and it is poor that the top of medium entrance 1 is set
Differential pressure transmitter 11 is set on pressure transmitter 2, media outlet 10, sets saddle 9 to be supported for equipment.
Medium enters horizontal desander from medium entrance 1, is entered by medium entrance 1 inside back-roll weldering stainless steel screen casing 7,
Flexible seal connecting mechanism is set to ensure good sealing property and detachability between medium entrance 1 and screen casing 7.Medium is from anti-
The filtering outflow of boxing stainless steel screen casing 7, the precision of back-roll weldering stainless steel screen casing 7 is not less than 0.10mm, it is ensured that filtering accuracy.Gravel
Stay in back-roll weldering stainless steel screen casing 7, the medium and liquid after filtering are after back-roll weldering stainless steel screen casing 7 flows out, then from medium
Flow out outlet 10.When normal sediment outflow operation, after the completion of the manual pressure release of drain 6, fast opening blind 8, dismounting back-roll are opened
Weld stainless steel screen casing 7 and complete sediment outflow.It is same to open fast opening blind 8, dismounting back-roll weldering when having unusual service condition or equipment must be checked
Stainless steel screen casing 7, on the contrary realize the installation of screen casing 7.
Between back-roll weldering stainless steel screen casing 7 and fast opening blind 8, provided with compacting device, it is ensured that close after fast opening blind, sieve
