Description
Technical field
The utility model is related to a kind of vertical 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 desander is Horizontal-type filtering structure, and aqueous and sand shale gas enters desander, sand grains along medium entrance
It is deposited in screen casing, gas and water and part sand pass through screen casing to downstream line.When sand grains is by desander downstream line and valve,
Pipeline and valve inwall can be washed away, causes the damage and the generation of accident of valve and pipeline.Sand grains is deposited to necessarily in screen casing
During amount, it is necessary to open the fast opening blind of desander, take out screen casing and clear up sand grains therein.Open in fast opening blind cleaning screen casing
Sand grains workload it is relatively complicated, and early stage operating frequency is high, and screen casing typically uses cutting seam sieve tube formula, and filtering accuracy is in 0.20mm
Left and right.
Found according to field practice, existing desander has some following deficiency：
First, the interference that the connection of desander and screen casing is used is connected, and the benefit of this connection is no gap, is easy to sieve
The sealing of pipe.Disadvantageously the dismounting of screen casing is inevitable, during dismounting, because using Hard link, end
Portion is easily damaged.
Second, the haydite that shale gas is used is general all between 0.1mm~0.5mm, using cutting seam sieve tube formula screen casing most
Small filter diameter is 0.20mm, therefore diameter is less than 0.20mm gravel, and the screen casing can not be separated, low separation efficiency.
3rd, the depositing gravel after filtering can block the circulation area of screen casing in screen casing, influence separative efficiency.

Further, the back-roll weldering stainless steel screen casing precision is 0.10mm, is set in back-roll weldering stainless steel screen casing bottom
There is handle.
Further, the opening device with sealing function is set in storage sand bucket bottom；Storage sand bucket bottom is provided with handle
Hand.
Further, discharge outlet is provided with fast opening blind.
Further, hanging support is set in the middle part of vertical cylinder.
Compared with prior art, the utility model has the advantages that：Desanding precision is improved, the damage to upstream device is reduced
Bad, sediment outflow is easy to operate, reduces operation difficulty.Specific manifestation is as follows：
1st, back-roll weldering stainless steel screen casing, storage sand bucket are easy for installation and removal using the seal form being easily attached, while by
Dismounting back-roll weldering stainless steel screen casing is not required to during desanding operation in this practicality, screen casing is not susceptible to destruction.
2nd, desanding precision is improved.Using vertical structure and back-roll weldering stainless steel screen casing, precision is in 0.10mm.
3rd, depositing gravel does not interfere with the circulation area of screen casing in storage sand bucket, while being provided with easily in storage sand bucket bottom
In the device of dismounting, sediment outflow operation is facilitated, labor intensity is reduced.
4th, due to the influence of Action of Gravity Field, under water, equipment medium outlet can be taken away covers storage to depositing gravel in storage sand bucket
The water of sand bucket, and depositing gravel is in storage sand bucket, it is to avoid screen casing is blocked because of water, it is ensured that the precision and circulating face of screen casing
Product.
5th, device bottom sets fast opening blind, and discharge outlet is provided with fast opening blind, when needing to open fast opening blind, first
Discharge outlet is opened, after water is drained, fast opening blind is then turned on, it is to avoid fluid spills when opening fast opening blind.
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 vertical filtering desander, as shown in figure 1, including：End socket 1, medium entrance 2, screen casing upper seal 3, shell
Body connector 4, back-roll weldering stainless steel screen casing 5, ear formula supporting 6, cylinder 7, media outlet 8, screen casing lower seal 9 store up sand bucket
Top support 10, storage sand bucket 11, discharge outlet 12, fast opening blind 13, storage sand bucket lower seals 14, wherein：
Medium entrance 2 is provided with the vertical top of filtering desander cylinder 7, middle part is provided with the top of media outlet 8, equipment and is provided with
