Abstract
The utility model provides a kind of reversed cleaning device of sewage treatment pipeline Inner filter net, including blow-off pipe and filter screen, filter screen is set in blow-off pipe, downstream side in blow-off pipe positioned at filter screen is horizontally arranged with multiple deflectors, vertically compartment is distributed the multiple deflector, scum pipe and flush pipe are also provided with and respectively communicated on the blow-off pipe of filter screen upstream and downstream, and flush pipe is set to the downstream of deflector, it is both provided with valve on scum pipe and flush pipe, valve is also equipped on the blow-off pipe of scum pipe upstream and on the blow-off pipe in flush pipe downstream.To solve in existing shale gas sewage disposal system, the impurity not easy-clear, and filter screen easily blocks in pipeline after filtering, not the problems such as easy care.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
It measures huge, and the row of returning is carried out to fracturing fluid after the completion of pressure break, the content for returning COD in sewerage is high, 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 encountered during to return sewerage in processing, so at the sewage of shale gas
Reason is always an insoluble problem.
To solve the sewage handling problem of shale gas, one kind is devised without using chemical agent, and water source will not be made
Into the sewage disposal system of secondary pollution, using electrochemical cell, by chemically and physically processing procedure, by the organic matter in sewage
And salt is discharged in solid form, achievees the purpose that contaminant degradation converts, the solid in sewage is gone out by filter screen filtration
Grain object, but setting filter screen in pipeline, the impurity not easy-clear, and filter screen easily blocks after filtering, not easy care.
Invention content
The purpose of this utility model is that：A kind of reversed cleaning device of sewage treatment pipeline Inner filter net is provided, it is existing to solve
Have in shale gas sewage disposal system, the impurity not easy-clear, and filter screen easily blocks in pipeline after filtering is not easy to tie up
The problems such as shield.
To solve the above problems, intend using such a reversed cleaning device of sewage treatment pipeline Inner filter net, including blowdown
Pipe and filter screen, filter screen are set in blow-off pipe, and the downstream side in blow-off pipe positioned at filter screen is horizontally arranged with multiple lead
Flowing plate, vertically compartment is distributed the multiple deflector, i.e., adjacent two deflector is vertically there are water conservancy diversion gap, filter screens
Scum pipe and flush pipe are also provided with and respectively communicated on the blow-off pipe of upstream and downstream, and flush pipe is set to the downstream of deflector, arranged
It is both provided with valve on slag pipe and flush pipe, is also equipped on the blow-off pipe of scum pipe upstream and on the blow-off pipe in flush pipe downstream
Valve.
In aforementioned cleaning device, deflector altogether there are five, five deflectors in blow-off pipe vertically equidistantly uniformly point
Cloth；
In aforementioned cleaning device, flush pipe is correspondingly arranged on water supply installation, for pressurizeing for the water of flushing pipe, and is pipe
It supplies water in road；
In aforementioned cleaning device, 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 is filtered, in the row of closing
Upper corresponding two valve is managed in dirt, also is able to after opening scum pipe and valve and water supply installation in flush pipe to filter screen and filtering
The blow-off pipe that net week is enclosed carries out back flush cleaning, in cleaning, separates water conservancy diversion to flushing liquor by deflector so that filter screen
Each position can be washed away by flushing liquor well, be effectively improved across strainer cleaning effect, solved sewage water filtration Netease and blocked up
It fills in and due to the problem of being difficult cleaning inside pipeline, and convenient for the dregs of removing filter screen filtration, effectively avoids blowdown pipe plug
Plug.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 be in Fig. 1 blow-off pipe A-A to cross-sectional view.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment：
Referring to Figures 1 and 2, a kind of reversed cleaning device of sewage treatment pipeline Inner filter net provided in this embodiment, including row
Dirty pipe 1 and filter screen 2, filter screen 2 are set in blow-off pipe 1, and the downstream side in blow-off pipe 1 positioned at filter screen 2 is transversely set
There are five deflector 3, five deflectors 3 are vertically equidistantly uniformly distributed in blow-off pipe 1, i.e., any adjacent two deflector 3
Vertically there are equidistant water conservancy diversion gap, 4 He of scum pipe is also provided with and respectively communicated on the blow-off pipe 1 of 2 upstream and downstream of filter screen
Flush pipe 5, and flush pipe 5 is set to the downstream of deflector 3, and valve 6, scum pipe 4 are both provided on scum pipe 4 and flush pipe 5
Valve 6 is also equipped on the blow-off pipe 1 of upstream and on the blow-off pipe 1 in 5 downstream of flush pipe, flush pipe 5 is correspondingly arranged on water supply dress
7 are put, for pressurizeing for the water of flushing pipe, and is piped water supply.
