Description
Technical field
The utility model relates to a kind of horizontal spiral discharge sedimentation centrifuge, relates in particular to a kind of sedimentation centrifuge that drilling waste water is processed.
Background technology
Drilling waste water is the mixture of drilling fluid dilution for many times liquid and oils, mainly water, clay, drilling cuttings, electrolyte, drilling fluid additive, oils etc., consists of, and has the feature of complexity, polytropy, dispersiveness, is one of very serious pollution sources in oil field.Its main source is solid controlling system entrained drilling fluid going out in separated landwaste process; The displacement fluid of discharging during each section of well cementation and a small amount of cement mortar, its amount is about tens sides at every turn; A large amount of aqueous slurries that during finishing drilling, clear water replaces out, rinse the large amount of sewage that pit shaft is discharged.
Along with the raising of environmental consciousness and the increasing of environmental protection supervision, strict control has been done to the generation of drilling waste water in each oil field, and the reuse of drilling waste water and processing have been done to many effort.Drilling company is by drilling wastes is carried out to classification analysis, and thinks that in conjunction with drilling technology feature the drilling fluid overwhelming majority in Discarded Drilling Materials thing can secondary utilization, only has drilling cuttings, sewage and part drilling fluid need to carry out harmless treatment.The job status that oil field drilling drilling team moves about requires not standby floor space little, compact conformation, and movement is good.Qualified discharge after drilling waste water will being processed, its processing links is numerous, and equipment is numerous and jumbled.
Utility model content
For addressing the above problem, the utility model provides a kind of compact conformation, equipment volume little, and migration is convenient, manually participates in less, automaticity is high, can move continuously the horizontal spiral discharge sedimentation centrifuge that clean effect is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of horizontal spiral discharge sedimentation centrifuge, comprises motor, auger stripper, turns hub, big-end bearing, little-end bearing, V band belt wheel, differential mechanism; The described hub that turns is provided with casing outward; The described hub that turns is divided into and turns the large end of hub and turn hub small end; Described auger stripper is located at turning in hub between big-end bearing and little-end bearing, and auger stripper stage casing is provided with liquid separating port, and auger stripper is provided with feed pipe near an intersegmental part that turns hub small end, and feed pipe extends to little-end bearing bending from liquid separating port; Described motor is divided into main motor and auxiliary motor, and main motor is connected with differential mechanism by V belt wheel with auxiliary motor; Described differential mechanism is connected with big-end bearing; The described large end of hub that turns is equipped with overflow weir, and is provided with liquid phase overfall.
Describedly turn hub and auger stripper closely cooperates, both do same-directional high-speed rotation, simultaneously, effect by differential mechanism, make the rotating speed of auger stripper have certain differential with the rotating speed that turns hub, spiral is rotated relative to turning hub, by falling to the solid phase that turns hub inner surface, to turning hub small end, release, reach the object of Separation of Solid and Liquid.
Preferably, the draw ratio of described horizontal spiral discharge sedimentation centrifuge is 4.4.
Preferably, described in, turning hub internal diameter is 350mm.
Overflow weir height design: the change impact of overflow radius turns the liquid pool degree of depth in hub, and overflow radius is larger, and the liquid pool degree of depth is less, and turbulence effect increases, and it is large that clear liquid solid content becomes.Overflow radius also affects and turns hub dry section length, when overflow radius becomes large, turns hub dry section elongated, and solid phase moisture content diminishes.Overflow radius is also that solid phase departs from liquid pool place, and overflow radius is large, and centrifugal force during solid phase dehydration is just large, and solid phase easily refluxes and do not move axially along circular motion, causes mud extraction difficulty.
Preferably, when described overflow weir height design is 199 mm, effluent quality is best, and water quality is more stable, and mud mass dryness fraction changes little.
Turn the size that hub rotating speed determines centrifuge centrifugal force.Centrifuge centrifugal force represents with separation factor, the centrifugal force that the material that its meaning is rotation is subject to and the ratio of gravity.In the adjustable range of speeds of centrifuge, with rotating speed, improve, centrifugal force increases, and sinking speed increases, but stirring is also large simultaneously, and water outlet solid content increases.When rotating speed increases, centrifugal force during solid phase dehydration increases, and solid phase easily forms at the taper position that turns hub and refluxes along circular motion, and under discharge auger effect, does not move axially, and reduces spiral dump efficiency.The mud viscosity that drilling waste water produces is larger, and after centrifugal force becomes greatly, it becomes large with the adhesion that turns hub, and the rotary resistance of discharge auger and promotion resistance are also large, also cause not mud extraction phenomenon.Therefore, be not that the higher separating effect of rotating speed is better, consider the factors such as maintenance cost, manufacturing cost and service life of centrifuge, meeting under the condition of technique, should select little separation factor as far as possible.
Preferably, the separation factor of horizontal spiral discharge sedimentation centrifuge is controlled in 1300 ~ 1 800 scopes.
Auger stripper is according to treating capacity, charging solid content, solid phase viscosity, clear liquid solid content, to require to do overall balance with solid phase water content requirement to consider with the poor rotating speed that turns hub.Poor rotating speed increases, and discharge auger relative rotation speed accelerates, and can reduce and be deposited in the solid phase thickness turning in hub; Reduce solid phase in the time of staying of dry section, increase moisture content; Increase the stirring degree of discharge auger to clear liquid, increase the muddy degree of liquid phase.
Preferably, differ from rotating speed and should be controlled at 5～12 r/min.
A kind of operation principle of horizontal spiral discharge sedimentation centrifuge: the drilling waste water of dosing coagulation enters and turns in hub through feed pipe and liquid separating port, with turning hub, rotate, the centrifugal force of rotation outwards throws away the larger floc sedimentation of density, fall to and turn hub inwall and be pushed to and turn hub small end and export by auger stripper, under centrifugal action, draw off, the liquid phase that density is less forms pendular ring, and the heavy component that particle is less continues outside sedimentation separation in pendular ring; Clear liquid is discharged from turning the overflow of the large end overflow weir of hub, and clear liquid pendular ring thickness regulates by weir plate height, and clear liquid pendular ring thickness determines liquid phase sedimentation time and solid phase dryer section length, after liquid phase overflow, from large end, discharges and enters fluid reservoir, and solid is arranged outward by mud-removing bucket.
The beneficial effects of the utility model are: a kind of horizontal spiral discharge sedimentation centrifuge, and continuous operation automatically, artificial participation less, automaticity is high, high to good sewage processing effect, mud cake solid content, compact conformation, operational management maintenance is easy, and transportation and processing cost are low.
