Embodiment:
With reference to the accompanying drawings, the present invention further is described
The present invention 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 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, the oil eliminator housing bottom is provided with V-arrangement mud-collecting slot 5, 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 forms, spacing between waved plate is that the spacing between waved plate is 5mm-40mm, determine as required, described waved plate is polyvinyl chloride or polypropylene or stainless steel, the angle of cut that the waved plate place forms is 15 degree-85 degree, and 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 (the AP work is published 421 water-and-oil separator standard and operational standards) according to U.S. AP work standard, the typical distance between plates between 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 also arranged.When waved plate is used when overstocked the greasy filth that can cause in waved plate dirty stifled.In order to address this problem, generally we just use high pressure water washing.The waved plate of large quantity theoretically can more effective removals oil, and the while also needs to safeguard more frequently.Spacing between waved plate is 10mm-20mm, and the angle of waved plate is generally between the 45-60 degree, and angle is larger, and the sedimentation congregational rate of mud is better.
The accumulation type filler is comprised of PVC or PP waved plate.Every waved plate is the 45-60 degree and combines, and between every waved plate, relies on the hasp of ripple connecting portion to bond.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, in waved plate, small turbulent flow helps oil droplet to assemble separation.
Be illustrated in figure 1 carbon steel ground type flocculent settling degreaser processed, the normal water inlet of design SS<300mg/l, interior influent turbidity is not more than 400mg/l in short-term, delivery turbidity is not more than 20mg/l, normal water inlet oleaginousness 500mg/L, water outlet oleaginousness 2mg/Lo the present invention can realize automatic control, can move continuously, the assurance effluent quality is even, but monitoring continuously.
Oily(waste)water enters flocculent settling degreaser by inlet pipe.Owing to being provided with the perforated pipe flow distribution apparatus in ingress, oily(waste)water, after changing flow direction, produces laminar flow stably, slowly enters intersection fluid-type waved plate, and this waved plate is called collector on chemical industry.This corrugated plate be take PVC as base mateiral, includes multiple additives, makes it have oleophylic and non-viscous oil, aging-resistant characteristics.Waved plate stacks up one by one, and distance between plates is 12.7mm.Usually the employing level is installed.When liquid flows through, oil droplet is caught rapidly by waved plate, can be gathered on waved plate, and separate with water.Principle due to collector, short grained oil droplet is easy to be caught by the waved plate of oleophylic, hyperchannel along waved plate after being caught by waved plate moves up and constantly is gathered into oarse-grained oil droplet, the oil droplet of larger particles is according to the Stokes principle, float to rapidly the surface of water-and-oil separator, profit is thoroughly separated.One oil trap is set in the fool flocculent settling degreaser, flows in oil trap when the sump oil of separating reaches certain thickness, but float in the regulating weir 4 inflow oil traps of sump oil by oil trap of the water surface, then flow into outside 1m by gravity
3pP material fuel tank in, thereby completed the whole process of oily water separation.
The flocculent settling degreaser bottom of device is established v shape mud-collecting slot 5, and the mud of collecting in mud-collecting slot is discharged by the screw rod slurry conveying machine, and sludge discharging period is 6 hours.The flocculation agent added by volume pump with after waste water fully mixes, forms oarse-grained alumen ustum in line mixer 7, and alumen ustum is settled down in V-arrangement mud groove in the flyover waved plate.
Flocculent settling degreaser adopts waved plate material one figure (3) of flyover formula, this material had both had the characteristic of waved plate, the moulding (60 ° of swash plate angles) that there is again swash plate, 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 medium temperature surpasses 85 ' C when above, can adopt stainless material, specification be high 1 foot, 2 feet, wide 1 foot, 2 feet, grow 4,6,8,10 feet.For non-metallic material, base mateiral contains multiple additives, makes it have oleophylic performance (but not viscous oil), anti-chemical, UV resistant and the characteristics such as anti-aging.Between plate, spacing is 12.7mm (for the waste water of high suspended matter, can adopt the design that spacing is 19mm).Therefore, when current pass through filler, short grained oil droplet, under the effect of gravity, only needs rising 12.7mm, can touch and hit the collector plate, by waved plate, is caught.We claim that this phenomenon is that gravity accelerates separation principle.Due to 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, with water body, separates fully.
According to Fig. 3, can find out, the waved plate of flyover formula is similar to the swash plate in inclined-plate clarifying basin, and it is except the passage that water stream channel, oil floating are provided, the same with inclined-plate clarifying basin, the passage that also provides suspended substance to sink, its slag removing function is the same with inclined-plate clarifying basin.And its slagging-off effect is better than inclined-plate clarifying basin, the direction of the plate of inclined-plate clarifying basin is consistent, and the direction of the plate of the waved plate of three-dimensional staggered form is intersected, and the contact area of particle and plate increases, more easily precipitation.
