Background technology:
Along with constantly riseing of world energy sources consumption, the unconventional energy resource including shale gas increasingly comes into one's own,
The states such as America & Canada have realized shale gas commercial development, and the reservoir of shale gas reservoir is typically the thing of low hole, low-permeability
Property feature, the resistance ratios conventional gas of air-flow is big, and all of well is required for implementing reservoir fracturing improvement could be mined, page
The necessary horizontal well drilling of rock gas exploitation and hydraulic fracturing technology water consumption are huge, and fracturing fluid to be entered after completing by pressure break
The row row of returning, different shale gas blocks, the row's of returning time of fracturing outlet liquid (including fracturing fluid and formation water) is different with volume, mesh
Under front technical conditions, the waste water of south shale gas well returns row and leads and be about 60%, and fracturing outlet liquid composition, in addition to water and the grains of sand, also contains
Have: the chemical addition agents such as dilute hydrochloric acid, guanidine glue, borate, polyacrylamide, mineral oil, citric acid, potassium chloride and petroleum hydrocarbon,
The pollutant such as high concentration salts, the fracturing fluid treatment returning row to shale gas brings the biggest difficulty；
At present discharge opeing is returned for pressure break type and process in the viscosity being concentrated mainly on reduction sewage, owing to fracturing fluid itself needs
Carrying the grains of sand for supporting stratum, so needing high viscosity to bring the grains of sand into down-hole, returning the fracturing fluid institute ejected
The viscosity having is that the key processed, currently mainly means have chemical method, the some method such as solution, biodegradation, the most just
It is being abolished by the chemical bond of macromolecular chain in fracturing fluid just must to make the as little as common sewage disposal means of viscosity drop of sewage
Manageable degree, whatsoever means viscosity reduction, be required for the highest energy consumption, along with the progress of fracturing fluid preparation technique, pressure
Splitting additive contained in liquid to differ, currently used various methods cannot adapt to the fracturing fluid of various composition.
Summary of the invention:
In order to solve the problems referred to above, it is contemplated that propose a kind of shale gas fracturing outlet liquid sewage-treatment plant.
The technical scheme is that shale gas fracturing outlet liquid sewage-treatment plant, including air buoyancy tank and high-speed cutting
Pump, high-speed cutting pump is made up of pump head and motor, and casing center one end of pump head is porose to be connected by mechanical seal matched in clearance
Power shaft, the porose connection in the other end center water inlet of housing, power shaft stretches into the Step Shaft in housing and connects impeller, and impeller is
Be welded and fixed the overall structure of connection by two panels blade and some impeller of being clipped between two panels blade, the most a piece of blade is fixed
Connecting power shaft, the blade of water inlet side has centre bore, and outside impeller, circumference has hammer leaf, hammer leaf to be connected by bearing pin
On two panels blade, being provided with sieve plate in the housing circumference outside hammer leaf, the housing tangential direction outside sieve plate has outlet, goes out
The tangent line Way out at the mouth of a river is identical with the direction of rotation of power shaft.
Described power shaft, its rotary speed is between 10000～15000rpm.
Being provided with sieve plate in housing circumference outside described hammer leaf, hammer leaf is opened maximum gauge and is existed with sieve plate internal diameter diameter
3～5mm gaps.
Described impeller 7, impeller 7 is arranged along even circumferential in the range of blade diameter, with place blade outside each impeller 7
Centrage outside arranged crosswise at an acute angle.
There is advantages that makes the macromolecular chain in fracturing outlet liquid rupture by mechanical energy cutting,
Can be without considering the composition of fracturing outlet liquid, adaptability is extensive, and treatment effect is stable, dirty for processing shale gas fracturing outlet liquid
Water brings a kind of new processing method, is simultaneously applicable to other high viscosity sewage disposals, favorably promotes the use of.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the structural representation of high speed cutting pump of the present invention；
Accompanying drawing 3 is the profile of accompanying drawing 2.
1-air buoyancy tank in figure, 2-high-speed cutting pump, 3-pump head, 4-motor, 5-housing, 6-water inlet, 7-impeller, 8-leaf
Wheel, 9-hammer leaf, 10-sieve plate, 11-outlet, 12-power shaft.
Detailed description of the invention:
The invention will be further described below in conjunction with the accompanying drawings:
Being combined shown in Fig. 2～3 by Fig. 1, shale gas fracturing outlet liquid sewage-treatment plant includes air buoyancy tank 1 and high-speed cutting
Pump 2, high-speed cutting pump 2 is made up of pump head 3 and motor 4, and one end, housing 5 center of pump head 3 is porose is joined by mechanical seal gap
Closing and connect power shaft 12, the porose connection in the other end center water inlet 6 of housing 5, power shaft 12 stretches into the Step Shaft in housing 5 even
Connecing impeller 8, impeller 8 is the overall structure being welded and fixed connection by two panels blade and some impeller 7 of being clipped between two panels blade,
Overall structure is firm, and post-treatment does dynamic balancing measurement, and to adapt to the needs of high speed rotating, the fixing connection of the most a piece of blade is defeated
Entering axle 12, the blade of water inlet 6 side has centre bore, and impeller 8 outer circumference is disposed with hammer leaf 9, and hammer leaf 9 is connected by bearing pin
On two panels blade, being provided with sieve plate 10 in housing 5 circumference outside hammer leaf 9, housing 5 tangential direction in outside has outlet
11, the tangent line Way out of outlet 11 is identical with the direction of rotation of power shaft 12.Described power shaft 12, its rotary speed exists
Between 10000～15000rpm, the hammer leaf speed of impeller diameter 300mm is up to 160～240m/s, and test proves in this speed
The energy of difference is repeatedly with by major part molecular chain scission, thus reduces viscosity.
Being provided with sieve plate 10 in housing 5 circumference outside described hammer leaf 9, hammer leaf 9 opens maximum gauge and sieve plate 10 internal diameter
There are 3～5mm gaps in diameter, gap is not easy greatly to produce the effect repeatedly cut, the little difficulty bringing process aspect in gap, examination
Testing data to show, this gap i.e. can reach cutting effect, and it is the highest to be unlikely to manufacturing cost.
Described impeller 7, impeller 7 is arranged along even circumferential in the range of blade diameter, with place blade outside each impeller 7
Centrage outside arranged crosswise at an acute angle, when impeller 8 rotates, impeller 7 produce centrifugal force suck fracturing outlet liquid.
The impeller 8 that fracturing outlet liquid is rotated sucks in pump head, is thrown to sieve plate 10 and hammer leaf 9 under the influence of centrifugal force
On, under static sieve plate 10 and the strike of hammer leaf 9 of high-speed motion, dissection, macromolecular chain is gradually cut off, and pressure break is returned
The viscosity of discharge opeing reduces, and the fracturing outlet liquid after viscosity reduction enters through air buoyancy tank or other common sewage disposal means after discharging
Row is up to standard after processing.
By mechanical energy cutting, the macromolecular chain in fracturing outlet liquid is ruptured, can be without considering fracturing outlet liquid
Composition, adaptability is extensive, and treatment effect is stable, brings a kind of new processing method for processing shale gas fracturing outlet liquid sewage,
It is simultaneously applicable to other high viscosity sewage disposals, favorably promotes the use of.
