Description

A kind of gas stripping type oily-water seperating equipment
Technical field
The utility model relates to field of environment protection, relates in particular to a kind of gas stripping type oily-water seperating equipment.
Background technology
Along with the petrochemical complex industrial expansion, the quantity discharged of oily(waste)water grows with each passing day, and its pollution to environment is also serious day by day.After oily(waste)water enters water bodys such as rivers,lakes and seas, oil reservoir covers the water surface, stop the diffusion of airborne oxygen in water, in the water body since dissolved oxygen reduce, thereby being restricted, the photosynthesis that algae carries out influences hydrobiological normal growth, make aquatic animals and plants that oil flavor or toxicity be arranged, even water body is fouled, destroy the utilization of water resources.Therefore, the processing oily(waste)water is significant.
The device of handling oily(waste)water in the market is a lot, but most complex structure, operation easier is big, the energy consumption height, and treatment effect is undesirable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of gas stripping type oily-water seperating equipment is provided.
But the gas stripping type oily-water seperating equipment comprises gas stripping type oily-water seperating equipment, oil-water mixture inlet, baffle plate, U type pipe floating cover, blast main, oil slick, bubble, swash plate, wash water valve, effluent weir, effluent pipe mouth; Be provided with the baffle plate that leaves the slit with the bottom in the gas stripping type oily-water seperating equipment, the baffle plate right side is provided with swash plate, swash plate lower-left end is provided with wash water valve, the swash plate upper right side is provided with effluent weir, effluent pipe mouth, be provided with U type pipe in the baffle plate left side, but floating cover is established in U type pipe one side end ingress, pressurized air feeds U type pipe opposite side bottom by blast main, U type pipe end side is outlet, and gas stripping type oily-water seperating equipment left upper portion sidewall is provided with the oil-water mixture inlet.
The utility model is simple in structure, be not easy to break down, power consumption is few, need not safeguard, can work automatically continuously, can divide skimming and heavy oil in the waste water substantially, and waste water does not almost have oil slick after this device is handled, and is that subsequent disposal is created good condition.
Description of drawings
Fig. 1 is the sectional view of gas stripping type oily-water seperating equipment synoptic diagram;
Fig. 2 is the vertical view of gas stripping type oily-water seperating equipment synoptic diagram;
Among the figure: but gas stripping type oily-water seperating equipment 1, oil-water mixture inlet 2, baffle plate 3, U type pipe 4 floating covers 5, blast main 6, oil slick 7, bubble 8, swash plate 9, wash water valve 10, effluent weir 11, effluent pipe mouth 12.
Embodiment
Be further elaborated below in conjunction with accompanying drawing:
As shown in the figure, but the gas stripping type oily-water seperating equipment comprises gas stripping type oily-water seperating equipment 1, oil-water mixture inlet 2, baffle plate 3, U type pipe 4 floating covers 5, blast main 6, swash plate 9, wash water valve 10, effluent weir 11, effluent pipe mouth 12; Be provided with the baffle plate 3 that leaves the slit with the bottom in the gas stripping type oily-water seperating equipment 1, baffle plate 3 right sides, be provided with swash plate 9, swash plate 9 lower-left ends are provided with wash water valve 10, and swash plate 9 upper right sides are provided with effluent weir 11, effluent pipe mouth 12, are provided with U type pipe 4 in the baffle plate left side, but floating cover 5 is established in U type pipe one side end ingress, pressurized air feeds U type pipe opposite side bottom by blast main 6, and U type pipe end side is outlet, and gas stripping type oily-water seperating equipment 1 left upper portion sidewall is provided with oil-water mixture inlet 2.
Working process of the present utility model is as follows:
After implementing the utility model, the oil slick disengaging zone, left side that the oil-water mixture that produces is introduced this device, under our device condition, the light oil come-up also is collected to the baffle plate left field, and oil slick is discharged from the outlet of U type pipe with bubble through U type pipe under compressed-air actuated drive; Heavy oil is discharged in bottom of device and by wash water valve by sloping plate deposition; Removing the waste water of oil slick and heavy oil separates from the rising pipe of clean liquid zone.The utility model has been used difference of specific gravity and the fluidic motion characteristics that exists between oil and the water, adopts the air floating method to separate oil slick, realizes fast and effeciently separating and reclaim the oil slick in the waste water.In the device, with not touching the baffle plate at the end under one device is not divided into 2 zones, leading portion is the oil slick disengaging zone, and back segment is clean liquid zone.Baffle plate top exceeds the about 10cm of liquid level, and the baffle plate bottom is from the about 20cm of bottom half.Oil-water mixture is entered by casing leading portion top, and in the oil slick disengaging zone, mixed solution flows forward with lower flow velocity, oil slick is floated, waste water enters the heavy oil disengaging zone by the baffle plate bottom, and heavy oil is deposited in bottom of device by swash plate, and discharges by bottom valve.Remove of the effluent weir outflow of the waste water of oil slick and heavy oil through clean liquid zone.Waste water in the clean liquid zone is discharged by the overflow port on device top.In the oil slick disengaging zone, utilize oil different with the density of water, oil with the water nature, separate, oil gently floats, oil slick also compiles and flows into the U type pipeline of particular design on the left of baffle plate; The pipeline that passes on left DN25 at U type pipe feeds pressurized air, and the oil slick in the U type pipe is along with bubble floats together, and discharges native system by the mouth of pipe that exceeds the water surface; The distance that U type pipe left side mouth of pipe height of center goes out the water surface is about blast main and enters U type pipe place apart from 1/3 of water surface distance.Certain chemical enterprise oily(waste)water is after this device is handled, and the oleaginousness in the waste water is reduced to 64mg/L from 621mg/L, and the oleaginousness clearance is 89.7%, and removal effect is obvious.
