Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
Water-oil separating portion in the present embodiment is primarily of rough segmentation cyclone 1 and the first to three cuff technique composition, oil mixing with water stoste is carried out rough segmentation by rough segmentation cyclone 1, the operation of cyclonic separation is also had because overflow is follow-up, so the overflow of rough segmentation cyclone to be not oil more pure better, consider mobility and the separability of overflow, the oil being preferably 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 purity of only unilateral pursuit rough segmentation cyclone 1 overflow, this oil is because too thick and cannot 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 be separated fuel-displaced or heavily assorted, but rough segmentation oil water mixture, the task of segmentation is placed on subsequent treatment.The water management of the second servo loop that the inlet pressure of rough segmentation cyclone 1 and flow are separated by the end i.e. underflow of three cuff technique in whole water-oil separating portion, three cuff technique has description later, if it is lower that rough segmentation cyclone 1 is selected in pressure, then improve pressure by moisturizing thus increase the oil mass entering overflow.The overflow that rough segmentation cyclone 1 is separated and the large branch road of underflow two, i.e. light item and heavy item, the application proposes an important sorting principle, namely for light item, improves the efficiency of separation; For heavy item, improve sharpness of separation.And carry out following apparatus arrangement according to this principle.
First cyclone 3 is designed to the purity ensureing overfall oil, the water of such overwhelming majority and the oil of a part enter underflow, charger 2 is preferably provided with in the first cyclone 3 porch, find in the practical operation of sorting, gas in cyclone when overfall eddy current catch end is close, there is very strong impetus to oil droplet, can help to collect oil droplet.First cyclone is in order to ensure the efficiency be separated, sacrifice the precision of sorting in a way, there is race oil to a certain degree, but the overflow item that rough segmentation cyclone 1 is separated and light item, only need a sorting just can ensure the purity of oil, 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 the eddy flow shunting only having carried out first this one-level of cyclone 3 just reaches high sorting standard, centre does not have loop gravity treatment, there is no the selected cyclone of multistage layout, this substantially reduces sorting flow process, improve the efficiency of separation.Three-phase Gravity Separation machine 4 is prior art, utilize the triangular gravity of gas, oil, water different with density and occur layering, be separated three-phase, the gas that charger 2 is filled with is discharged from exhaust outlet after upwards being floated from aqueous phase by oil in three-phase Gravity Separation machine.
Second cyclone 5 is also the cyclone designed based on the purity of overfall oil, the underflow of rough segmentation cyclone 1 and the first cyclone 3 enters the second cyclone 5, through being separated, second cyclone 5 overflow is that high-purity oil enters three-phase Gravity Separation machine 4, underflow is the water, heavily assorted of sub-fraction oil and the overwhelming majority, and underflow enters three cuff technique 6.Three cuff technique 6 is designed to ensure not occur oil in underflow, for this reason, relax the requirement of the overflow of three cuff technique 6 as far as possible, more water can be there is and turn back to the arrival end of the second cyclone 5 in the overflow of three cuff technique 6, underflow due to three cuff technique 6 is the three groove trash separators that directly will enter water treatment stage, therefore requirement that will be stricter for the underflow of three cuff technique 6, detecting devices is all established at the overfall of three cuff technique 6 and underflow opening, two detecting devices are connected with detector 7, the overfall of three cuff technique 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 three cuff technique 6 into, also there is the entrance that water is guided into rough segmentation cyclone 1 by second servo loop.
When the underflow of three cuff technique 6 be detected Equipment Inspection go out to have oil to run out of time, second control valve 9 pairs underflow current limliting, water is forced to overfall, 3rd control valve 10 in the first loop is opened simultaneously, to the entrance moisturizing of three cuff technique 6, also be the process of supercharging, the oil in three cuff technique 6 moves to overfall more fully simultaneously.If when there is too many water in the overfall of three cuff technique 6, the problem not existing and run oil is described in underflow, the operating pressure that in overflow, water increases the second cyclone 5 too much on the contrary, overall sorting capability declines, at this moment the first control valve 8 current limliting, water is forced out underflow opening, ensures 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, treat that the component ratio of point mixed flow is stable, therefore for detector 7, also can artificial sampling detect, this can't pay the artificial of larger amount.
Rough segmentation cyclone 1 and the first cyclone 3 underflow form through the 2nd three cuff technique select the high-precision You Heshui that has been separated of structure for closed circuit time, and introduce detector 7, more ensure that the reliability of water-oil separating.All in all water-oil separating part, overflow for rough segmentation cyclone 1 adopts high efficiency water-oil separating, and the cyclone that be mixed by the underflow of rough segmentation cyclone 1 underflow and the first cyclone feeding second and three cuff technique form selects structure for closed circuit time, by the sorting across branch road, form the sorting focused on efficiency and focus on separation accuracy mixed principle.In the water-oil separating of reality, the production capacity of what we paid close attention to is valuable oil, oil yield is substantially constant for oil well, we reduce the layout to the complexity of light item branch road for this reason, all sorting errors are all concentrated on heavy item branch road, can increase or reduce the group number of the closed circuit Hui Xuan of cyclone according to the actual needs, also second can be adjusted according to production capacity, three cuff technique number separately, focus for whole production just concentrates on heavy item branch road, and this branch road also introduces the detector 7 automatically controlled, reduce further the difficulty of control, for the closed-loop path of the 2nd three cuff technique composition, just the overfall of the second cyclone and the underflow of three cuff technique are paid close attention to, overflow for three cuff technique is general concern, it is only the auxiliary detection for underflow discharge.System is selected again in the cyclone composition loop that closed-loop path does not have employing more than three grades or three grades, this is because as previously described, cyclone is a kind of screening installation of adjustability difference, cyclone level can affect what sharpness of separation last too much, sometimes needs to use pump class to ensure selected pressure.So the closed circuit Hui Xuan that the application only adopts the cyclone of two-stage to form, and be furnished with detector 7, can also adjust the quantity of the cyclone of any one-level, thus be suitable for the sorting of the oil water mixture of different moisture content.
Continuous seepage due to water-oil separating portion causes an important technical problem, namely create a large amount of containing heavily assorted middle water, according to the standard of China's mining industry draining, this kind of water cannot directly discharge, therefore need one can continuous seepage, water treatment system that disposal ability is large support water-oil separating portion, otherwise whole oil-water separation system just cannot run normally.For this reason, inventor proposes three groove trash separators 11, effectively solves this technical problem.
Three groove trash separators 11 are made up of the first to three groove, the aqueous phase of three-phase Gravity Separation machine 4 mixes the first-stage tank together being entered three groove trash separators 11 by first-stage tank entrance 12 with the underflow of three cuff technique, the exit normal of first-stage tank entrance 12 is downward, the port of export has water flow speed reduction device, water flow speed reduction 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 first-stage tank again by the slow of curved grooves.First-stage tank is subsider, the heavily assorted bottom being deposited in first-stage tank as much as possible, and being preferably first-stage tank has the higher degree of depth, and bottom first-stage tank during impurities removal, first-stage tank water level decreasing also goes out impurity discharging port by heavily assorted.Be connected by one-way pump 14 between first-stage tank with second-level groove, one-way pump 14, from first-stage tank outlet 13 to second-level groove entrance 15 pumping clarified solution, it should be noted that first-stage tank outlet 13 should away from first-stage tank entrance 12, prevent current short circuit from crossing first-stage tank and directly enter second-level groove, thus first-stage tank was lost efficacy.The second-level groove entrance 15 of second-level groove and second-level groove are tiltedly installed with sieve structure between exporting 16, sieve structure is for removing the granule easily suspended, but sieve structure has a shortcoming to need periodic cleaning exactly, the short grained compass screen surface of sorting is different from other compass screen surface, granule is very easy to block discharges in sieve aperture instead of along compass screen surface downslide, 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 to have in the prior art and granule do 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, be a two-way pump structure 17 between second-level groove and three grades of grooves in the present embodiment, when water treatment, water after filtration is exported 16 pumps to three grades of groove entrances 18 by second-level groove by two-way pump structure 17, when compass screen surface blocks, compass screen surface can increase due to the effect deflection of hydraulic pressure, the water-head of compass screen surface both sides also can become large, what those skilled in the art can know is, can utilize including but not limited to deflection and water level difference to judge whether compass screen surface blocks, when 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 second-level groove, by discharging to the effect of compass screen surface reverse cleaning the granule blocked at compass screen surface, granule glides and discharges with the impurity discharging port 20 of current from second-level groove, preferably export 16 places in second-level groove and be provided with impeller, when second-level groove exports 16 reverse drainage, waterborne raising is 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 that second-level groove entrance 15 sprays and second-level groove export 16 water sprayed and form combined-flow, and combined-flow disturbance is comparatively strong, better discharges granule.Therefore, no matter be water treatment or impurities removal stage, whole three groove trash separators are operating always, and for the continual process of middle water in water-oil separating stage, the needing of solution shuts down clear assorted or change the technical barrier of compass screen surface.
Although carried out special description with reference to embodiment to the disclosed oil-water separation method related to; embodiment described above is illustrative and not restrictive; without departing from the present invention, all changes and amendment are all within protection scope of the present invention.
