Description
Technical field
The present invention 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,
So the various problems such as the situation for being difficult to be uniformly processed can be run into during sewerage is returned in processing, so the sewage of shale gas
Processing 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, achieve the purpose that contaminant degradation converts, the solid in sewage is gone out by filter screen filtration
Grain thing, but filter screen is set in pipeline, due to being arranged inside pipeline, filter screen easily blocks, it is difficult to safeguard and replace.
The content of the invention
It is an object of the invention to：A kind of detachable filter structure in sewage treatment pipeline is provided, to solve
In existing shale gas sewage disposal system, pipeline filtering net easily blocks, it is difficult to the problem of safeguarding and replacing.
To solve the above problems, intend using such a detachable filter structure in sewage treatment pipeline, bag
Blow-off pipe and filter screen are included, the strainer insert port perpendicular to blow-off pipe axial direction, strainer insert port are offered on the outer wall of blow-off pipe
Width it is identical with the thickness of filter screen, filter screen is inserted in blow-off pipe by strainer insert port, the diameter and blow-off pipe of filter screen
Internal diameter it is identical, the upper end of filter screen is along the circumferential direction fixedly installed arc sealing strip, and the shape and ruler on ring packing side
Very little to match with the shape of strainer insert port and size, the seam crossing on ring packing side and strainer insert port on the outside of blow-off pipe applies
There is sealing material, and detachable reinforcing annular lasso is provided with corresponding ring packing side on the outside of blow-off pipe.
In foregoing filter structure, the edge of filter screen is provided with reinforcing steel ring；
In foregoing filter structure, the radian of strainer insert port is 180 degree.
Compared with prior art, the present invention returns sewerage to shale gas using filter screen and filters, and filter screen is lateral
Demountable, the maintenance and replacement of filter screen are very convenient, easy to pipeline follow-up maintenance, save maintenance cost.
Brief description of the drawings

Fig. 2 is the left view of blow-off pipe in Fig. 1；
Fig. 3 is the positive structure schematic of filter screen；
Fig. 4 is the structure diagram of blow-off pipe in Fig. 1.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
Embodiment：
Referring to figs. 1 to Fig. 4, a kind of detachable filter structure in sewage treatment pipeline provided in this embodiment,
Including blow-off pipe 1 and filter screen 2, offered on the outer wall of blow-off pipe 1 perpendicular to the axial strainer insert port 101 of blow-off pipe 1, filter
The radian of net insert port 101 is 180 degree, and the width of strainer insert port 101 is identical with the thickness of filter screen 2, and filter screen 2 is by strainer
Insert port 101 is inserted in blow-off pipe 1, and the diameter of filter screen 2 is identical with the internal diameter of blow-off pipe 1, and the edge of filter screen 2 is set
There is a reinforcing steel ring, the upper end of filter screen 2 is along the circumferential direction fixedly installed arc sealing strip 201, and ring packing side 201
The shape and size of shape and size and strainer insert port 101 match, the ring packing side 201 in the outside of blow-off pipe 1 and strainer
The seam crossing of insert port 101 scribbles sealing material, and is provided with the corresponding ring packing side 201 in the outside of blow-off pipe 1 detachable
Reinforcing annular lasso 3.
