Abstract
The utility model provides a kind of automatically cleaning shale gas and returns sewage filtering unit, including blow-off pipe and filter screen, filter screen is arranged in blow-off pipe, scum pipe and flush pipe are provided with and respectively communicated with the blow-off pipe of filter screen upstream and downstream, flush pipe is correspondingly arranged on water supply installation, valve is both provided with scum pipe and flush pipe, and valve is also equipped with the blow-off pipe on the blow-off pipe of scum pipe upstream and flush pipe downstream.To solve the problems such as filter screen of existing equipment is not easy to clean, and the dregs after filtering are not easily cleaned out blow-off line, easy blocking blow-off pipe.The utility model belongs to shale gas development technique field.
Description
Technical field
The utility model provides a kind of shale gas and returns sewage filtering unit, belongs to shale gas development technique field.
Background technology
For the development technique of shale gas mainly using hydraulic fracturing, hydraulic fracturing method is by part chemicals at present
The mixture of matter, water and silt injects missile silo by high pressure, the shale reservoir construction near pressure break, to absorption and free page
Rock gas creates hole crack passage, is conducive to collect shale gas.The reservoir of shale gas reservoir is generally in low hole, the physical property of low-permeability
Feature, the resistance ratios conventional gas of air-flow is big, horizontal well drilling and hydraulic fracturing technology water consumption necessary to shale gas exploitation
Measure huge, and the row of returning is carried out to fracturing fluid after the completion of pressure break, it is high to return the content of COD in sewerage, about 5000~
10000mg/L, the requirement of the level-one B classes far above standard GB/T 18918-1002, since the distribution of shale gas block relatively dissipates, institute
The various problems such as the situation for being difficult to be uniformly processed can be run into during to return sewerage in processing, so at the sewage of shale gas
Reason is always an insoluble problem.
At present, shale gas returns that blowdown water treatment facilities are not easy to clean there are filter screen, and the dregs after filtering are not easily cleaned out
The problems such as blow-off line, easily blocking blow-off pipe.
The content of the invention
The purpose of this utility model is that：A kind of automatically cleaning shale gas is provided and returns sewage filtering unit, it is existing to solve
The filter screen of equipment is not easy to clean, and the dregs after filtering are not easily cleaned out blow-off line, easy the problems such as blocking blow-off pipe.
To solve the above problems, intend returning sewage filtering unit, including blow-off pipe using such a automatically cleaning shale gas
And filter screen, filter screen are arranged in blow-off pipe, scum pipe and punching are provided with and respectively communicated with the blow-off pipe of filter screen upstream and downstream
Pipe is washed, flush pipe is correspondingly arranged on water supply installation, and valve, and the blowdown of scum pipe upstream are both provided with scum pipe and flush pipe
Valve is also equipped with the blow-off pipe on pipe and flush pipe downstream.
In aforesaid filtering plant, further included dreg collecting slot, one end of the scum pipe with the blow-off pipe of filter screen upstream
Side is connected, and the other end of scum pipe is extended in dreg collecting slot；
In aforesaid filtering plant, flush pipe is directly connected with running water pipe.
Compared with prior art, the utility model returns sewerage to shale gas using filter screen and filters, in the row of closing
Upper corresponding two valve is managed in dirt, and opening can also be to filter screen and filtering after scum pipe and valve and water supply installation in flush pipe
The blow-off pipe that net week is enclosed carries out back flush cleaning, solves sewage water filtration Netease and blocks and due to being difficult cleaning inside pipeline
The problem of, and easy to remove the dregs of filter screen filtration, effectively avoid blowdown blockage.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment：
With reference to Fig. 1, a kind of automatically cleaning shale gas provided in this embodiment returns sewage filtering unit, including 1 He of blow-off pipe
Filter screen 2, filter screen 2 are arranged in blow-off pipe 1, and scum pipe 3 is provided with and respectively communicated with the blow-off pipe 1 of 2 upstream and downstream of filter screen
With flush pipe 4, and scum pipe 3 is connected with the downside of 2 upstream blow-off pipe 1 of filter screen, and the other end of scum pipe 3 extends dreg collecting slot
In 7, flush pipe 4 is correspondingly arranged on water supply installation 5, and valve 6, and 3 upstream of scum pipe are both provided with scum pipe 3 and flush pipe 4
Blow-off pipe 1 on and 4 downstream of flush pipe blow-off pipe 1 on be also equipped with valve 6.
