The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe.

The utility model provides a kind of device for water-oil separating, and as shown in Figure 1 to Figure 3, the device is by gravitational method It is combined with coalescence technology, improves hydraulics, enhances the state of the water-oil separating of oil emulsion.

The device for water-oil separating as shown in Figure 1 to Figure 3, including cylinder 11, in cylinder 11 by front baffle 12 and after Partition plate 13 is divided into intake chamber 22, separation chamber 23 and goes out grease chamber 24, the double M types coalescing-plate groups fixed in separation chamber 23 equipped with spacing 10, double tops of M types coalescing-plate group 10 are fixed in front baffle 12 and rear bulkhead 13 by fixed plate 7, and bottom is fixed by foundation 8 In on cylinder 11, side is fixed in front baffle 12 and rear bulkhead 13 by tabletting 9.

The barrel top of intake chamber 22 is equipped with L-type inlet tube 19, and bottom is equipped with the silt discharge pipe 26 that can be periodically turned on, into Tilted upward in liquid chamber 22 on the inner wall of the lower section of silt discharge pipe 26 equipped with every husky plate 17, cylinder 11 is welded in every husky plate 17 On, and horizontal by 45° angle.

The position away from inlet tube 19, which is equipped with, in front baffle 12 can make the passage 27 that intake chamber 22 communicates with separation chamber 23； The position away from passage 27 is equipped with the secondary separation room 25 that is made of secondary separation plate 14 and barrel in separation chamber 23, secondary point Overflow pipe 28 setting up and down is equipped with from 14 bottom of plate, the cylinder of 25 lower part of secondary separation room is secondary equipped with that can periodically turn on Outlet pipe 21.

The cylinder lower part of separation chamber 23 is equipped with water outlet 18, and front and rear the two of double M type coalescing-plates groups 10 are located in separation chamber 23 Side is respectively equipped with opening up oil exit pipe 1 and oil exit pipe 2 16, and oil exit pipe 1 and oil exit pipe 2 16 are L-type, L-type Outlet be welded on rear bulkhead 13；The spout tops position of oil exit pipe 1 and oil exit pipe 2 16 is less than double M type coalescing-plate groups 10 apical position.The cylinder for going out grease chamber 24 is equipped with flowline 20.

Double M types coalescing-plate groups 10 include the coalescing-plate 60 stacked on top together, as shown in Fig. 4 to Fig. 8, coalescing-plate bag The coalescing-plate body 1 that cross section is M types is included, coalescing-plate body 1 is in wavy, edge on the M types top of coalescing-plate body 1 along longitudinal direction Longitudinal direction is equipped with oil slick hole 2 on wavy wave crest, and trough is equipped with sedimentation hole 1, is set at the node between wave crest and trough There is the fore-set 3 of protrusion.The M type bottom centers of coalescing-plate body 1 distribute sedimentation hole 26, the back side of coalescing-plate body 1 along the longitudinal Groove 5 is equipped with positioned at the lower position of fore-set 3,3 front end of fore-set of lower floor's coalescing-plate is inserted into the groove 5 of upper strata coalescing-plate.

As shown in figure 5, oil slick hole 2 is uniformly arranged on the wave crest of coalescing-plate body 1, sedimentation hole 1 is uniformly arranged on poly- On the trough of knot tying body 1, fore-set 3 is uniformly arranged at the node between wave crest and trough, and sedimentation hole 26 is uniformly arranged on poly- On the M type bottom center lines of knot tying body 1.

The board selection polypropylene of coalescing-plate, adds bone meal, to polypropylene board in polypropylene board manufacturing process Tow sides are modified processing.Modified mechanism is hydroxyl in the positive and negative grafting of basic unit, makes it have strong oleophilic drainage Characteristic, so as to realize emulsified oil droplet be demulsified after grease rapid coalescence.

Specific separation process is as follows：

Oil emulsion is inputted in the intake chamber 22 of cylinder 11 with suitable flow by inlet tube 19；Into the emulsification of cylinder 11 Oil is encountered every husky plate 17 during flowing downward, and under the action of husky plate 17, along every husky 17 direction of plate to the left Top is flowed, so that avoiding oil emulsion from directly flowing to the particulate matters such as 11 bottom of cylinder, silt can sink under the action of husky plate Product arrives cylinder body bottom, can periodically open silt discharge pipe 26 and discharge cylinder 11.

Passage 27 of the oil emulsion Jing Guo front baffle 12 into intake chamber 22 enters in separation chamber 23, oil emulsion lateral flow Into M type coalescing-plates group 10, the surface of coalescing-plate is waveform, its tortuous passageway provided and very big coalescence surface, production The current similar to sine wave have been given birth to, has made surface collision during tiny oil droplets bottom horizontal flow sheet in coalescing-plate, coalescence, works as oil droplet When diameter coalescence is to certain particle diameter, oil droplet starts to float by the oil slick hole on 10 top of M type coalescing-plates group, and oil content is relatively low to be mixed Liquid is closed to start to sink by the sedimentation hole 1 and sedimentation hole 26 of 10 bottom of M type coalescing-plates group.Oil droplet by coalescing-plate layer by layer by The top of cylinder 11 is gradually floated up to, the relatively low mixed liquor of oil content sinks down into 11 bottom of cylinder by coalescing-plate layer by layer, from water outlet 18 discharges, floating up to the oil droplet at the top of cylinder 11 can enter grease chamber 24 by oil exit pipe 1 and oil exit pipe 2 16, then from Flowline 20 is discharged outside cylinder 11, carries out the first time recycling of oil droplet.

The relatively low mixed liquor of 11 bottom oil content of cylinder is secondary into being formed by secondary separation plate 14 via overflow pipe 28 Separation chamber 25, under the effect of gravity, mixed liquor form layering, and the of a relatively high mixed liquor of oil content is located at top, and oil content Relatively lower mixed liquor is located at lower part, periodically opens secondary outlet pipe 21, and the low water of oil content is discharged, and forms the of grease Secondary separation.

The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The most wide scope consistent with features of novelty.
