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 oily water separating equipment, structure as depicted in figs. 1 and 2, the equipment gravitational method with Coalescence technology is combined, and improves hydraulics, enhances the state of the water-oil separating of oil emulsion.

Oily-water seperating equipment as depicted in figs. 1 and 2, including babinet 11,11 top of babinet are equipped with inlet tube 16 and oil extraction Pipe 15, lower part are equipped with discharge outlet 18, and middle part is equipped with the secondary drainage mouth 12 that can be periodically turned on；It is located on babinet 11 under inlet tube 16 Side is welded with the flow-stopping plate 17 set horizontal by 45° angle, and secondary drainage mouth 12 is located at by babinet 11 and secondary oil dividing plate 14 The secondary separation room lower part of composition, secondary oil dividing plate 14 are L-type, are welded on the upper left of babinet 11, second for grease Secondary separation；Overflow pipe 13 is setting up and down in the bottom of L-type, and the spout tops position of overflow pipe 13 is less than the mouth of pipe top of oil exit pipe 15 End position.

Inlet tube 16 and oil exit pipe 15 are L-type, and the outlet of inlet tube 16 is positioned at the top of flow-stopping plate 17；Oil exit pipe 15 is logical The oil discharge outlet for crossing babinet 11 is installed on babinet 11, and the apical position of the mouth of pipe is less than the apical position of double M type coalescing-plates groups 10.

The double M types coalescing-plate groups 10 fixed in babinet 11 equipped with spacing, double tops of M types coalescing-plate group 10 pass through fixed press strip 7 are fixed on cabinet wall, and cabinet wall is fixed in side by tabletting 21.As shown in figure 8, fixed press strip 7 is equipped with handle, it is double The lower section of M type coalescing-plates group 10 is equipped with bottom plate, and string column 9 is equipped between fixed press strip 7 and bottom plate 8, and string column 9 passes through double M type coalescing-plates Group 10.String column 9 passes through oil slick hole 2, and the top of string column 9 is installed on fixed press strip 7 by locking cap 20, and the bottom of string column 9 is consolidated Due on bottom plate 8.

As shown in Fig. 3 to Fig. 7, coalescing-plate includes the coalescing-plate body 1 that cross section is double M types, and coalescing-plate body 1 is along longitudinal direction In wavy, oil slick hole 2 is equipped with wavy wave crest along longitudinal direction on double M types tops of coalescing-plate body 1, trough is equipped with Sedimentation hole 1, raised fore-set 3 is equipped with the node between wave crest and trough.Double M types bottom center edges of coalescing-plate body 1 Genesis analysis has a sedimentation hole 26, and the lower position that the back side of coalescing-plate body 1 is located at fore-set 3 is equipped with groove 5, lower floor's coalescence In the groove 5 of 3 front end of the fore-set insertion upper strata coalescing-plate of plate.

As shown in figure 4, 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 double M types 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 babinet 11 with suitable flow by inlet tube 16；Into babinet 11 oil emulsion to flow down In dynamic process, flow-stopping plate 17 is encountered, and under the action of flow-stopping plate 17, is flowed along 17 direction of flow-stopping plate to upper left side, So as to avoid oil emulsion from directly flowing to 11 bottom of babinet.

Oil emulsion lateral flow enters double M type coalescing-plates groups 10, and the surface of coalescing-plate is waveform, its complications provided is led to Road and very big coalescence surface, generate the current similar to sine wave, make coalescing during tiny oil droplets bottom horizontal flow sheet The surface collision of plate, coalescence, when droplet diameter is coalesced to certain particle diameter, oil droplet passes through the floating of double 10 tops of M types coalescing-plate group Oilhole starts to float, the sedimentation hole 1 and sedimentation hole 26 that the relatively low mixed liquor of oil content passes through double 10 bottoms of M types coalescing-plate group Start to sink.Oil droplet gradually floats up to the top of babinet 11 by coalescing-plate layer by layer, and the relatively low mixed liquor of oil content by gathering layer by layer Knot tying sinks down into 11 bottom of babinet, is discharged from discharge outlet 18, floats up to the oil droplet at the top of babinet 11 and can be exported by oil exit pipe Outside babinet 11, the first time recycling of oil droplet is carried out.

The relatively low mixed liquor of 11 bottom oil content of babinet is secondary into being formed by secondary oil dividing plate 14 via overflow pipe 13 Separation chamber, 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 phase Lower part is located to lower mixed liquor, periodically opens secondary drainage mouth 12, the low water of oil content is discharged into outdoor, forms grease Second of 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.
