Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
Water-oil separating portion in the present embodiment is mainly made up of rough segmentation cyclone 1 and the first to three cyclone, oil mixing with water stoste is carried out rough segmentation by rough segmentation cyclone 1, also has the operation of cyclonic separation because overflow is follow-up, so it is more pure better that the overflow of rough segmentation cyclone is not oil, consider mobility and the separability of overflow, being preferably the oil of 70%-75% in stoste enters overflow item and enters the first cyclone 3, remaining oil, water and major part be heavily assorted to enter underflow and introduces the second cyclone 5, if the only purity of unilateral pursuit rough segmentation cyclone 1 overflow, this oil is because too thick and cyclonic separation again, and the selected amount of whole piece-rate system reduces greatly, therefore the separation theory in the application is thought, in the cyclonic separation of initial one-level, should directly not separate fuel-displaced or heavily assorted, but rough segmentation oil water mixture, the task of segmentation is placed on to subsequent treatment.The inlet pressure of rough segmentation cyclone 1 and flow are by the water management of the end second servo loop that underflow of the 3rd cyclone separates of whole water-oil separating portion, the 3rd cyclone has description later, if the selected pressure of rough segmentation cyclone 1 is lower, increase thereby improve pressure by moisturizing the oil mass that enters overflow.Two large branch roads of the overflow separating for rough segmentation cyclone 1 and underflow, light and heavy, the application proposes an important sorting principle, for light, improves the efficiency of separation; For heavy, improve sharpness of separation.And carry out following apparatus arrangement according to this principle.
The first cyclone 3 is designed to ensure the purity of overfall oil, the water of the overwhelming majority and a part of oil enter underflow like this, preferably be provided with charger 2 in the first cyclone 3 porch, in the practical operation of sorting, find, gas in cyclone to overfall eddy current catch end near time, oil droplet is had to very strong impetus, can help to collect oil droplet.The efficiency of the first cyclone in order to ensure to separate, sacrifice in a way the precision of sorting, there is race oil to a certain degree, but light of the overflow item of separating for rough segmentation cyclone 1, only need a sorting just can ensure oily purity, it contains a small amount of water, hardly containing heavily assorted, this is a kind of well protection to follow-up three-phase Gravity Separation machine 4 and other accurate screening installation, that is to say that the eddy flow shunting of only having carried out first cyclone 3 these one-levels has just reached high sorting standard, centre does not have loop gravity treatment, there is no the selected cyclone of multistage layout, this has shortened sorting flow process greatly, improve the efficiency of separation.Three-phase Gravity Separation machine 4 is prior art, utilize gas, oil, the triangular gravity of water different with density and occur layering, three-phase is separated, after the gas that charger 2 is filled with upwards floats oil in three-phase Gravity Separation machine from water, discharge from exhaust outlet.
The second cyclone 5 is also the cyclone of the purity design based on overfall oil, the underflow of rough segmentation cyclone 1 and the first cyclone 3 enters the second cyclone 5, through separating, the second cyclone 5 overflows are that high-purity oil enters three-phase Gravity Separation machine 4, underflow is the oily and most water of sub-fraction, heavily assorted, and underflow enters the 3rd cyclone 6.The 3rd cyclone 6 is designed to ensure do not occur in underflow oil, for this reason, relax the requirement of the overflow of the 3rd cyclone 6 as far as possible, can there is more water and turn back to the arrival end of the second cyclone 5 in the overflow of the 3rd cyclone 6, because the underflow of the 3rd cyclone 6 is the three-flute trash separators that will directly enter water treatment stage, therefore requirement that will be stricter for the underflow of the 3rd cyclone 6, overfall and underflow opening at the 3rd cyclone 6 are all established detecting devices, two detecting devices are connected with detector 7, the overfall of the 3rd cyclone 6 and underflow opening are also provided with the first control valve 8 and the second control valve 9, underflow also has the first loop Jiang Shui to guide the entrance of the 3rd cyclone 6 into, also there is second servo loop and water is guided into the entrance of rough segmentation cyclone 1.
In the time that the underflow of the 3rd cyclone 6 is detected Equipment Inspection and goes out to have oil to run out of, the second control valve 9 is to underflow current limliting, water is forced to overfall, the 3rd control valve 10 in the first loop is opened simultaneously, to the entrance moisturizing of the 3rd cyclone 6, also be the process of supercharging, the oil in the 3rd cyclone 6 moves to overfall more fully simultaneously.If while there is too many water in the overfall of the 3rd cyclone 6, illustrate and in underflow, do not have the oily problem of running, the operating pressure that in overflow, water has strengthened the second cyclone 5 too much on the contrary, the sorting capability of entirety declines, at this moment the first control valve 8 current limlitings, water is forced out to underflow opening, ensure that in overflow, oil is controlled with the ratio of water.Detector 7 and detecting devices itself are prior aries, do not repeat them here; It is emphasized that for water-oil separating field, the component ratio for the treatment of point mixed flow is stable, therefore for detector 7, also can artificial sampling detect, and this can't pay the artificial of larger amount.
3 underflow of rough segmentation cyclone 1 and the first cyclone selects the high-precision You Heshui that separated of structure for closed circuit time through the two or three cyclone composition, and introduces detector 7, has more ensured the reliability of water-oil separating.All in all water-oil separating part, adopt high efficiency water-oil separating for the overflow of rough segmentation cyclone 1, and by the underflow of rough segmentation cyclone 1 underflow and the first cyclone be mixed send into second and the cyclone of the 3rd cyclone composition select structure for closed circuit time, by the sorting across branch road, form the sorting of focusing on efficiency and focusing on separation accuracy mixed principle.In actual water-oil separating, what we paid close attention to is the production capacity of valuable oil, oil yield is substantially constant for oil well, we reduce the complicated layout to light branch road for this reason, all sorting errors are all concentrated on a heavy branch road, can increase according to the actual needs or reduce the group number of the closed circuit Hui Xuan of cyclone, also can adjust second according to production capacity, three cyclones number separately, just concentrate on a heavy branch road for the focus of whole production, and this branch road has also been introduced the detector 7 of automatic control, further reduce the difficulty of controlling, for the closed-loop path of the two or three cyclone composition, just the overfall to the second cyclone and the underflow of the 3rd cyclone are paid close attention to, be general concern for the overflow of the 3rd cyclone, it is only the auxiliary detection for underflow discharge.Closed-loop path does not adopt more than three grades or three grades cyclones composition loops to select system again, this is because as noted earlier, cyclone is the poor screening installation of a kind of adjustability, cyclone level can affect finally what sharpness of separation too much, sometimes needs to ensure selected pressure by pump class.So the application only adopts the closed circuit Hui Xuan of the cyclone composition of two-stage, and is furnished with detector 7, can also adjust the quantity of the cyclone of any one-level, thereby be suitable for the sorting of the oil water mixture of different moisture content.
Because the continuous production of water-oil separating portion causes an important technical problem, produced a large amount of heavily assorted middle water that contains, according to the standard of China's mining industry draining, this class water cannot directly discharge, therefore need one can produce continuously, water treatment system that disposal ability is large supports water-oil separating portion, otherwise whole oil-water separation system just cannot move normally.For this reason, inventor proposes a three-flute trash separator 11, has effectively solved this technical problem.
Three-flute trash separator 11 forms to three-flute by first, the water of three-phase Gravity Separation machine 4 mixes the one-level groove that together enters three-flute trash separator 11 by one-level groove entrance 12 with the underflow of the 3rd cyclone, the outlet of one-level groove entrance 12 vertically downward, the port of export has current deceleration device, current deceleration device is preferably shunting disk, shunting disk is the horizontally disposed disk with radial curved grooves, and current, under the guiding of shunting disk, enter one-level groove slowly again by curved grooves.One-level groove is subsider, the heavily assorted bottom that is deposited in as much as possible one-level groove, and being preferably one-level groove has the higher degree of depth, and in the time of the impurities removal of one-level trench bottom, one-level groove water level declines and will heavily mix and go out impurity discharging port.Between one-level groove and secondary groove, be connected by one-way pump 14, one-way pump 14, from the outlet 13 of one-level groove to secondary groove entrance 15 pumping clarified solutions, it should be noted that one-level groove outlet 13 should be away from one-level groove entrance 12, prevent that current short circuit from crossing one-level groove and directly entering secondary groove, thereby one-level groove was lost efficacy.Between the secondary groove entrance 15 of secondary groove and secondary groove outlet 16, be tiltedly installed with sieve structure, sieve structure is for removing the granule of easy suspension, but sieve structure has a shortcoming to need exactly periodic cleaning, the short grained compass screen surface of sorting is different from other compass screen surface, granule is very easy to block in sieve aperture instead of along compass screen surface and glides and discharge, if mesh is blocked to a certain extent in prior art, just must shut down cleaning or change compass screen surface, this cannot adapt to aforesaid water-oil separating part, certainly also have in the prior art and granule is not processed and directly discharge, only that bulky grain or similar easy recovery section are reclaimed, but this causes huge pressure to plant area's surrounding enviroment.
In order to solve this technical problem, in the present embodiment, between secondary groove and three grades of grooves, be a two-way pump structure 17, in the time of water treatment, two-way pump structure 17 exports 16 pumps to three grades of groove entrances 18 by the water after filtering by secondary groove, in the time that compass screen surface blocks, compass screen surface is because the effect deflection of hydraulic pressure can increase, it is large that the water-head of compass screen surface both sides also can become, what those skilled in the art can know is, can utilize including but not limited to deflection and water level difference and judge whether compass screen surface blocks, in the time that testing agency finds that compass screen surface blocks, two-way pump structure reversing pump water, the water of three grades of grooves is oppositely fed to secondary groove, discharge the granule blocking at compass screen surface by the effect to compass screen surface reverse cleaning, granule glides and discharges from the impurity discharging port 20 of secondary groove with current, preferably export 16 places at secondary groove and be provided with impeller, when secondary groove exports 16 reverse drainage, waterborne raising washed away compass screen surface by impeller.In the impurities removal stage, the work of one-way pump 14 does not stop, and the water of the water that secondary groove entrance 15 sprays and secondary groove outlet 16 ejections forms combined-flow, and combined-flow disturbance is stronger, better discharges granule.Therefore, no matter be water treatment or impurities removal stage, whole three-flute trash separator turn round always, for the continual processing of middle water in water-oil separating stage, solution need to shut down the technical barrier of mixing clearly or changing compass screen surface.
Although the disclosed oil-water separation method relating to has been carried out to special description with reference to embodiment; embodiment described above is illustrative and not restrictive; without departing from the present invention, all variations and amendment are all within protection scope of the present invention.
