nullEmbodiment 1: in embodiment as shown in Figures 1 to 4，A kind of oil-contained waste water treatment device，Including cyclone separator、Stoste groove 1、Collecting tank 2，Described cyclone separator includes that profile is round table-like separation cone 3、Cone is coaxial to be connected and vertical tail pipe 4 with separating，Separate on cone、The equal opening in lower end，On tail pipe、The equal opening in lower end，Separate cone upper end open more than separating cone lower ending opening，Tail pipe upper end open connects with separating cone lower ending opening，Separate cone upper end open to be sealed by a vertex of a cone plectane 31，Separate the tangential direction pipe 32 that cone is provided with and separates the internal connection of cone，Collecting tank is in below tail pipe，Also include a stoste draw-off pump 11，Stoste draw-off pump be provided with stoste draw-off pump inlet communication enter stoste pipe 12、With stoste draw-off pump outlet go out stoste pipe 13，The entrance point entering stoste pipe stretches in stoste groove，The port of export going out stoste pipe connects with tangential direction pipe，The core pipe 5 coaxial with tail pipe it is provided with in cyclone separator，Core pipe upper end is through vertex of a cone plectane and stretches out outside cyclone separator，Core pipe upper end is connected to an accumulator tank 51 by oil-collecting pipeline，Core pipe is provided with some pipe fuel feed holes 52 of connecting internal with core pipe.Described tangential direction pipe axis is tangential parallel with separate cone one.Oil-polluted water (seawater) is stored in stoste groove, stoste draw-off pump extracts stoste (oil-polluted water) from stoste groove, oil-polluted water is through entering stoste pipe, stoste draw-off pump, going out stoste pipe and reach tangential direction pipe, and send in separation cone from tangential direction pipe with tangential (or approximation is tangential), up big and down small owing to separating cone, again due to the effect of gravity, oil-polluted water starts helical flow in separating cone, and overall trend is downward spiral flowing.Owing to having density contrast between profit, during oil-polluted water high-speed rotational, water can against separation conical inner surface relatively, and oil droplet (oily) can shift to center (near separating axis of cone line) relatively.And along with the entirety of fluid is downward, spiral moves, cross section constantly reduces, and oil continues move towards center and converges into wick (core pipe is in wick), and wick outer layer is then " water wall " (a large amount of water oil on a small quantity).Fluid then goes through mouth (tail pipe), and fluid can produce back pressure to epimere, make the upwards overflow of low pressure wick, enter into inside core pipe from pipe fuel feed hole, and be collected in entering accumulator tank by oil-collecting pipeline, as for outer layer " water wall ", then it is discharged in collecting tank down through tail pipe lower ending opening, thus efficiently separating of profit can be realized, and without by additional chemical agent, equipment also can reuse, and processing procedure is very continuous, and overall cost is relatively low.
Described separate cone in be provided with the equal opening of upper and lower end help rotation cylinder 33, described in help rotation cylinder with separate cone coaxial, help rotation cylinder upper end and vertex of a cone plectane between being tightly connected, help rotation cylinder height more than separation cone height 2/3rds.The described cylinder top side wall helping rotation cylinder is provided with some return ports 331.Help the existence of rotation cylinder, be equivalent to constitute one section of circular passage (help rotation cylinder and separate between cone), contribute to the formation of eddy flow, flow up (as previously mentioned on can also suppressing, owing to the formed wick of back pressure and a part against " the water wall " of wick) to excessive dissipate formed disturb stream in a large number, the stability of processing procedure can be promoted.But, rise and flow to local eddy currents that external diffusion formed and flow-disturbing still exists, and the setting of return port, up-flow can be allowed to rise to top after, a part flows out from return port, feed liquor is formed opposing back pressure, controls the balance of feed liquor on the whole, improve regularity and the stability separating cone interior fluid flowing the most further, can effectively promote the oil-water separation of entirety.
nullThe self-regulated pipe joint 53 that can relatively slide up and down in core pipe it is provided with in described core pipe，On self-regulated pipe joint、The equal opening in lower end，Between self-regulated pipe joint lateral wall with core pipe madial wall, slipper seal coordinates，Self-regulated pipe joint lower end is stretched out outside core pipe，Self-regulated pipe joint lower end is provided with shrouding 531 under the pipe sealing self-regulated pipe joint lower ending opening，The lower shrouding of pipe is provided with buoyancy aid 532，Buoyancy aid is provided with floating foundation seat 533，Tail pipe is provided with the guiding montant 534 being connected with tail pipe，Guide montant cross section rectangular，Guide montant to be slidably connected with floating foundation seat，The slidably direction of floating foundation seat is above-below direction，Self-regulation tube side wall is provided with some pipe oil throughs 535 of connecting internal with self-regulated pipe joint，Pipe oil through and pipe fuel feed hole one_to_one corresponding，Corresponding pipe oil through with in pipe fuel feed hole: pipe oil through aperture is identical with pipe fuel feed hole aperture，Pipe oil through and pipe fuel feed hole dead in line.Described guiding montant is connected with tail pipe by support body, and described support body includes at least horizontal connecting rod 41, and horizontal connecting rod one end is fixed with tail pipe madial wall, guides montant lower end and is connected with horizontal connecting rod.Some brake pads 42 fixing with tail pipe it are provided with in tail pipe, brake pad contact self-regulated pipe joint lateral wall, at the beginning, owing to fluid oil content is bigger, now buoyancy aid part contact water, remaining part contact oil, now the buoyancy suffered by buoyancy aid is also not sufficient to exceed gravity (self-regulated pipe joint, the gravity of whole float structure etc.) and frictional force (the mainly frictional force between brake pad and self-regulated pipe joint, remaining fraction is the frictional force etc. between self-regulated pipe joint and core pipe) sum, so self-regulated pipe joint will not slide up and down, so crossing the total bore (aperture of pipe oil through pipe fuel feed hole in other words of oil, namely oil enters total bore of self-regulated pipe joint) constant, the most fuel-displaced.And when fluid oil content reduces (when original oil content is the highest in other words), wick can become very carefully, wick length also can reduce (wick hypomere part is replaced with water), " water wall " can become the thickest, owing to now water is too close to pipe fuel feed hole, if the oil-feed speed of self-regulated pipe joint, it is easily caused water and enters core pipe (self-regulated pipe joint), the oil-containing ratio of the oil that impact is collected.And in this programme, after fluid oil content is reduced to a certain degree, owing to wick shortens, so the part of buoyancy aid contact water becomes many, the part of contact oil tails off, the buoyancy that buoyancy aid is subject to increases, at a time, buoyancy has exceeded gravity (self-regulated pipe joint, the gravity of whole float structure etc.) and frictional force (the mainly frictional force between brake pad and self-regulated pipe joint, remaining fraction is the frictional force etc. between self-regulated pipe joint and core pipe) sum, buoyancy aid starts to drive shifting on self-regulated pipe joint, thus pipe oil through and pipe fuel feed hole start dislocation, cross the total bore of oil to diminish, thus, the oil-feed speed in self-regulated pipe joint can be reduced, such that it is able to ensure that still only oil enters self-regulated pipe joint, avoid a part of water entrance self-regulated pipe joint now caused because feed liquor speed is too fast.Accordingly, fluid oil content is the lowest, and it is the most that buoyancy aid drives self-regulated pipe joint to rise, and crosses the total bore of oil the least, it is achieved thereby that cross being automatically adjusted of the total bore of oil.And, after fluid oil content is reduced to a certain degree, (surrounded by water completely outside buoyancy aid owing to buoyancy aid drives the rising of self-regulated pipe joint to reach extreme position, the buoyancy that buoyancy aid is subject to is all from water), now pipe oil through and pipe fuel feed hole stagger completely, oil-collecting pipeline stops oil-collecting, has thoroughly blocked when fluid oil content is the lowest, and water enters the possibility of oil-collecting pipeline.
Described oil-collecting pipeline includes oil-collecting supervisor 54, transition connecting pipe 55, and oil-collecting is responsible for one end and is connected with accumulator tank, and oil-collecting supervisor's other end connects with transition connecting pipe one end, and the transition connecting pipe other end connects with core pipe upper end.Described oil-collecting supervisor is provided with collection oil pump 56, oil-collecting check valve 57, the drawing liquid direction of collection oil pump is to collecting oil pump by core pipe, the discharge opeing direction of collection oil pump is to accumulator tank by collection oil pump, Tong Guo the direction of oil-collecting check valve is to accumulator tank by collection oil pump, goes out and is provided with feed liquor on-off valve 131 between stoste pipe and tangential direction pipe.Controllability and the accuracy of processing procedure can be promoted by each pump, valve.
nullAlso include electricity flocculation post processing structure、Post processing pump 61，Electricity flocculation post processing structure includes processing container 62、Post processing feed tube 63、Post processing drain pipe 64，Post processing feed tube is provided with some liquid inlet head 631 connected with post processing feed tube，Post processing drain pipe is provided with some liqiud outlet heads 641 connected with post processing drain pipe，Process in container and be provided with row's arc-shaped electrode plate 65，Adjacent two blocks of arc-shaped electrode plates surround a process single-chamber in processing container，Process single-chamber and liquid inlet head one_to_one corresponding，Process single-chamber and liqiud outlet head one_to_one corresponding，Liquid inlet head、Liqiud outlet head is all in the process single-chamber of correspondence，Post processing pump be provided with post-process that pump inlet connects enter treatment fluid pipe 66、With post processing pump discharge connect go out treatment fluid pipe 67，The entrance point entering treatment fluid pipe stretches in collecting tank，The port of export going out treatment fluid pipe connects with post processing feed tube，Go out treatment fluid pipe and be provided with out treatment fluid on-off valve 671.After aforementioned separating treatment, the treatment fluid oil content of discharge is the lowest, and the most again by if physical method oil removing, effect is the most inconspicuous, so using electricity flocculence, can promote final treatment effect.The alfer plate that battery lead plate can use iron content to be 10%.Because simple aluminum electrode plate produces Al (OH)3Flocculant has preferable removal effect to oil emulsion most in oil-polluted water and suspended oil, poor to dissolved oil (COD) removal effect of oil-polluted water small portion.And alfer battery lead plate can produce and have certain oxidisability Fe3+, therefore the dissolved oil of oxidable small molecule structure.Battery lead plate can use semicircle perpendicular stream warp architecture form, flocculation efficiency is improved relative to the electrode plate structure of advection, and the battery lead plate bent can also increase oil-polluted water flow distance in the reactor, add the oil-polluted water reaction time, therefore can fully remove the oil in oil-polluted water and divide and pollutant.Battery lead plate can exchange a both positive and negative polarity every one end time, it is to avoid near battery lead plate, concentration polarization causes water electrolysis and the electric energy loss that produces.
