Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of flocculent settling degreaser, it mainly comprises the oil eliminator housing, it is characterized in that: described oil eliminator housing one side is provided with inlet pipe 1, oil eliminator housing opposite side is provided with outlet pipe 9, inlet pipe 1 place is provided with perforated pipe flow distribution apparatus 8, perforated pipe flow distribution apparatus 8 tops are provided with line mixer 7, be provided with intersection fluid-type waved plate mechanism 2 in the oil eliminator housing, one side of intersection fluid-type waved plate mechanism 2 is a perforated pipe flow distribution apparatus 8, the opposite side of intersection fluid-type waved plate mechanism 2 is provided with oil trap 3, but oil trap 3 places are provided with regulating weir 4, and the oil eliminator housing bottom is provided with V-arrangement mud-collecting slot 5, and V-arrangement mud-collecting slot 5 places are provided with screw rod slurry conveying machine 6.
In the specific implementation, described intersection fluid-type waved plate mechanism 2 is by being parallel to each other and horizontally disposed waved plate constitutes, spacing between the waved plate is 10mm-20mm, decide as required, described waved plate is a polyvinyl chloride, hard chlorine polyethylene and polypropylene, stainless steel, described oil eliminator housing bottom is provided with water shoot 10, and described intersection fluid-type waved plate mechanism 2 tops are provided with baffle plate 11.
Water (flow) direction is normally along the waved plate percolation or to dirty.Recommend (API publishes 421 water-and-oil separator standard and operational standards) according to U.S. API standard, the typical distance between plates between the waved plate is between 0.75 to 1.5 inch.Yet the case of successfully using when reducing to 0.25 inch, distance between plates is arranged also.When waved plate uses the greasy filth that can cause when overstocked in the waved plate dirty stifled.Generally we just use high pressure water washing in order to address this problem.The waved plate of big quantity theoretically can more effective removals oil, and the while also needs more frequent maintenance.Generally between the 45-60 degree, angle is big more for the angle of waved plate, and the sedimentation congregational rate of mud is good more.
The accumulation type filler is made up of PVC or PP waved plate.Every waved plate is the 45-60 degree and combines, and relies on the hasp of ripple connecting portion to bond between the every waved plate.Therefore form the space of relative percolation, guaranteed the passage of current.The waved plate medium of percolation forces current chop and change direction, and this helps little elaioleucite to contact with the surface collision of waved plate.Advection separates very important for liquid liquid, small turbulent flow helps oil droplet to assemble separation in the waved plate.
The carbon steel system of being illustrated in figure 1 as ground type flocculent settling degreaser, the normal water inlet of design SS≤300mg/l, interior in short-term influent turbidity is not more than 400mg/l, and delivery turbidity is not more than 20mg/l, the oleaginousness≤500mg/L of normally intaking, water outlet oleaginousness≤2mg/L.The utility model can be realized automatic control, can move continuously, guarantees that effluent quality is even, but monitoring continuously.
Oily(waste)water enters flocculent settling degreaser by inlet pipe.Owing to be provided with the perforated pipe flow distribution apparatus in ingress, oily(waste)water produces laminar flow stably after changing flow direction, slowly enters intersection fluid-type waved plate, and this waved plate is called collector on chemical industry.This corrugated plate is a base mateiral with PVC, includes multiple additives, makes it have oleophylic and sticking oily, aging-resistant characteristics.Waved plate stacks up one by one, and distance between plates is 12.7mm.Usually the employing level is installed.When the liquid flow mistake, oil droplet is caught rapidly by waved plate, promptly can accumulate on the waved plate, and come with water sepn.Because the principle of collector, short grained oil droplet is easy to be caught by lipophilic waved plate, being caught the back by waved plate moves up and constantly is gathered into oarse-grained oil droplet along the hyperchannel of waved plate, the oil droplet of larger particles is according to the Stokes principle, float to the surface of water-and-oil separator rapidly, profit is thoroughly separated.
One oil trap is set in the flocculent settling degreaser, flows into when the sump oil of separating reaches certain thickness in the oil trap, but on float to the water surface the regulating weir 4 of sump oil by oil trap flow in the oil traps, flow into outside 1m by gravity again
3PP material fuel tank in, thereby finished the whole process of oily water separation.
The flocculent settling degreaser bottom of device is established V-arrangement mud-collecting slot 5, and the mud of collecting in the mud-collecting slot is discharged by the screw rod slurry conveying machine, and sludge discharging period is 6 hours.The flocculation agent that adds by volume pump in line mixer 7 with the waste water thorough mixing after, form oarse-grained alumen ustum, alumen ustum is settled down in the flyover waved plate in the V-arrangement mud groove.
Flocculent settling degreaser adopts the waved plate material of flyover formula--figure (3), this material had both had the characteristic of waved plate, the moulding (60 ° of swash plate angles) that has swash plate again, flyover formula waved plate adopts PVC (temperature can reach 60 ℃), HPVC (high-temperature PVC, temperature can reach 65 ℃) and three kinds of materials of PP (polypropylene, temperature can reach 85 ℃).But when medium temperature surpasses more than 85 ℃, can adopt stainless material, specification be high 1 foot, 2 feet, wide 1 foot, 2 feet, long 4,6,8,10 feet.For non-metallic material, base mateiral contains multiple additives, makes it have oleophylic performance (but sticking oil), anti-chemical, UV resistant and characteristics such as anti-aging.Spacing is 12.7mm (for the waste water of high suspended matter, can adopt spacing is the design of 19mm) between plate.Therefore, when current passed through filler, short grained oil droplet only needed rising 12.7mm under the effect of gravity, can touch and hit the collector plate, is promptly caught by waved plate.We claim that this phenomenon is that gravity quickens separation principle.Because the effect of collector, short grained oil droplet can be gathered into larger oil droplet, and oil droplet upwards flows along the plate structure of filler.According to the stocks law, the oil droplet of larger particles can climb up on top of the water rapidly, separates fully with water body.
According to Fig. 3 as can be seen, the waved plate of flyover formula is similar to the swash plate in the inclined-plate clarifying basin, and it is except the passage that water stream channel, oil come-up are provided, and is the same with inclined-plate clarifying basin, the passage that also provides suspended substance to sink, its slagging-off function is the same with inclined-plate clarifying basin.And its slagging-off effect is better than inclined-plate clarifying basin, the direction unanimity of the plate of inclined-plate clarifying basin, and the direction of the plate of the waved plate of three-dimensional staggered form is intersected, the contact area of particle and plate increases, easier precipitation.
