Abstract

The utility model relates to an oil-water separator for removing floating oil. The utility model belongs to the technical field of oil-water separation. The utility model is characterized in that utilizing the heights of layers from top and bottom, which is caused by different densities of the oil and the water, the utility model uses baffle plates to segment different regions and uses a flow guiding plate to force the floating oil to float upwards in a fixed direction to flow out from a collecting pipe. The oil-water separator can continuously work on line; after the oil and the water are separated, no floating oil phenomenon is visually inspected; since oil stain in a washing liquid is timely eliminated, the consumption of a cleaning agent is reduced, consequently, the discharge amount of waste water is reduced, and the oil-water separator causes the discharged waste water to be easier to approach to the requirement of environment protection. The oil-water separator for removing floating oil is a good design favorable for environment protection.

Description

A kind of oily-water seperating equipment of removing oil slick

Technical field: belonging to the oily water separation technique field, exactly is a kind of suction type oily water separation technique that relates to.

Background technology: clean the field at industrial part, organic solvent commonly used, aqueous cleaning agent clean greasy dirt.When using aqueous cleaning agent to clean greasy dirt, because the effect of clean-out system internal surfactants produces the emulsion, the thumping majority greasy dirt can swim in the scavenging solution surface except that a small amount of greasy dirt.The salver oil wiper and the belt-type oil skimmer that generally use the skim milk principle to make on the market, but the effect of oily water separation is undesirable, the one, do not have adsorptive power and can not carry out oily water separation fully; The 2nd, take too much tensio-active agent during skim milk out of, shorten clean-out system work-ing life, increase wastewater discharge.When these clean-out system dischargings, improved the wastewater treatment difficulty, also pollute the environment.

Summary of the invention: the utility model is that a kind of work automatically continuously in process of production will be provided, and strengthens cleaning performance, reduces a kind of oily-water seperating equipment of removing oil slick of discharge of wastewater.

The technical scheme that the utility model is taked:

In the casing, not contour by three, up and down at most, the plate washer separation casing that does not touch the end down is four zones, the area of slack water, nascent disengaging zone, disengaging zone, clean liquid zone, the top of the 1st plate washer is the highest, and a narrow and small plano-convex platform is arranged, a topped sealing sloping baffle between the lower edge of the overflow port that becomes with the bending dihedral on inferior high top, outside the overflow port place is provided with a net flow recovery tube and pass-out case, be a transparent panel on the boss face, it is provided with the vertical oil exit pipe of a band oil extraction regulating sleeve down, and passes the 3rd plate washer from level, pass clean liquid zone, pass the back by casing and vertically bend down; The slant block board that oriented wash water valve doorway, case bottom tilts, at the bottom of slant block board and the 2nd plate washer between the edge opening be clean liquid porthole; Liquid absorbing pump is placed on the case outer support, and the oil-water mixture liquid-inlet pipe that links to each other with liquid absorbing pump is by casing elbow above the area of slack water.

After implementing the utility model,, send into the area of slack water of this device by liquid absorbing pump with the oil-water mixture that produces, utilize oil different with the density of water, under our device condition, oil and water natural separation, oil gently floats, discharge from the pipeline of particular design, and water is separated from clean liquid zone, can work automatically continuously like this, separates fuel-displaced and water from the utility model device, reduce the wastewater treatment difficulty, also reduced environmental pollution.

Description of drawings:

Fig. 1 is the utility model structural principle synoptic diagram;

Fig. 2 is the utility model stereoscopic-state synoptic diagram.。

Embodiment:

Now the utility model is described in further detail in conjunction with the accompanying drawings.In the casing 3, by three not contour, on not at most, it is four zones that the plate washer 5,7,9 that does not touch down the end is separated casings, 4,6,8,10.The top of plate washer 5 is the highest, and a narrow and small plano-convex platform 22 is arranged, and a topped sealing sloping baffle 11 between the lower edge of the overflow port 6 that becomes with the bending dihedral on inferior high top 9 is outside overflow port (16) locates to be provided with a net flow recovery tube 17 and pass-out case.On 22 of the boss is a transparent panel 23, and it is provided with the vertical oil exit pipe 15 of a band oil extraction regulating sleeve 12 down, and passes plate washer 9 from level, passes clean liquid zone 10, and it is vertical curved down to pass the back by case 3; The slant block board 21 of 19 mouthfuls of inclinations of the case oriented sewage draining valve in bottom, opening is clean liquid porthole 20 between slant block board 21 and the edge, 7 ends of plate washer; Liquid absorbing pump 1 is placed on the case outer support 18, and the profit mixing liquid-inlet pipe 2 that links to each other with liquid absorbing pump is by casing 3 elbow above area of slack water 4.

Now in conjunction with the accompanying drawings the principle of work of this device is done an explanation:

The liquid absorbing pump 1 that is installed on the water pump support 18 extracts pending oil-water mixture from the outside, enter area of slack water 4 via liquid-inlet pipe 2; Oil-water mixture enters initial gross separation district 6 from area of slack water plate washer 5 belows; Oil-water mixture flows owing to mild in initial gross separation district 6, the oil come-up, heavy under water, the water that sinks enters clean liquid zone 10 through clean liquid passage 20 disengaging zone 8 of flowing through, and the clean liquid in the clean liquid zone 10 upwards flow to clean liquid recovery and export 17 and get back in the fluid storage tank through overflow port 16 flows to flow deflector 11 above and along flow deflector 11 inclined-planes.Oil slick enters disengaging zone 8 above disengaging zone plate washer 7, owing to density and height reason, the oil slick that enters in the disengaging zone 8 can not sink, and can only make progress to float below upper edge flow deflector 11, and oil slick arrival oil extraction regulating sleeve 12 upper edge holes that upwards float slip in the oil exit pipe 15 discharges.
