But the present invention has the normal pressure operation also can be with pressure operation, device structure flexible (placement can be stood and can be crouched), minimizing to add advantages such as dose, operating cost is low, floor space is little, also solved the problem of the easy fouling of pole plate, can be widely used in oil field, oil, petrochemical industry oily waste water treatment, the tertiary oil recovery sewage disposal of oilfield exploitation later stage, also can be applicable to simultaneously salinity height such as leather, pesticide wastewater, Industrial Wastewater Treatment that electrical conductivity is bigger, also be suitable for handling salinity height such as polluted water of leather production and part pesticide producing sewage, the sewage that conductance is bigger.
For concentrating oil gas, lateral partitions of the present invention is the taper that the middle part is higher than periphery.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
As shown in Figure 1, lower bottom part at casing 13 is provided with water inlet 1, the lateral partitions 5 that casing 13 inner chambers is divided into upper and lower two chambeies (cavity of resorption is that the electric floating chamber of one-level, epicoele are the electric floating chamber of secondary) is set in casing 13, and lateral partitions 5 is higher than the taper of periphery for the middle part.The top of lateral partitions 5 be provided with casing 13 outside the oil extraction exhaust outlet A6 that is communicated with.
Below the lateral partitions 5 of casing 13 inner chambers, be provided with uprightly, uprightly be connected casing 13 lower bottom parts, between upper end and the lateral partitions 5 gap is set to the lower end of baffle plate A4 to baffle plate A4.Upright side to baffle plate A4 at casing 13 inner chambers is arranged electrode A 3, and water inlet 1 is arranged with electrode A 3 homonymies.Arrange one-level liquid outlet 14 at upright opposite side to baffle plate A4.
Below the electrode A 3,, between transverse baffle A2 and casing 13 sidewalls gap is set in the upright transverse baffle A2 that on baffle plate A4, connects.
Above the lateral partitions 5 of casing 13 inner chambers, be provided with uprightly, uprightly be connected with lateral partitions 5, between upper end and casing 13 tops gap is set to the lower end of baffle plate B10 to baffle plate B10.At the upright transverse baffle B12 that on baffle plate B10, connects, between transverse baffle B12 and casing 13 sidewalls gap is set.
At upright casing 13 sidewalls below baffle plate B10 one side, transverse baffle 12B secondary inlet 15 is set, in the upright electrode B 11 of above baffle plate B10 homonymy, transverse baffle 12B, arranging.Arrange upright at upright opposite side to plate washer C7 to baffle plate B10, stand and be connected with casing 13 tops to the upper end of plate washer C7, between lower end and the lateral partitions 5 gap is set, laying out the mouth of a river 8 away from a upright upright side, oil extraction exhaust outlet B9 is being set at casing 13 tops of upright opposite side to plate washer C7 to plate washer C7 to plate washer B10.
The present invention can look the sewage quality situation and select for use single-stage or two kinds of structures of two-stage to handle.
With the electric floating example that is treated to of two-stage, oil-contaminated water of oil field is entered the buffering area I of horizontal plate washer A2 below by water inlet 1, enter the electric floating region II of one-level that electroplax A3 is installed after the buffering, led to liquid generation cell reaction in the zone between galvanic electrode A 3 pole plates this moment, produce hydrogen at negative electrode, anode produces chlorine and oxygen, discharges through oil extraction exhaust outlet A6 to the separation chamber of baffle plate A4 opposite side III rear section suspension and elaioleucite by standing to enter to stand on baffle plate A4.
Water through the electric floating processing of one-level is gone out by one-level liquid outlet 14, after the dosing, enter medicament reaction zone IV between lateral partitions 5 and the transverse baffle B12 by secondary inlet 15, mixed oil-polluted water enters the electric floating region V of the secondary that electrode B 11 is set, air supporting is handled the back and is entered Disengagement zone VI by upright to baffle plate B10 upper end, oil and suspension are discharged through oil extraction exhaust outlet B9, and the final water after the processing enters water chamber VII and discharges through delivery port 8.
One-level handle to be removed big elaioleucite and suspension, and water outlet is flowed out through the electric emersion of the one-level mouth of a river, is connected with dosing pipe this moment and flows into the electric floating chamber of secondary;
Sewage after the dosing enters the mixing buffering area of the electric floating chamber of secondary, enters electric floating treatment region after the buffering and enter the Disengagement zone to separate, and oil gas flows out through the oil extraction exhaust outlet, finally handles qualified water and flows out from delivery port.
Owing to also contain metal ions such as a large amount of calcium, iron in the output water of oil field, and the hydroxide ion of generation produces for example calcium hydroxide (Ca (OH) when react with catholyte
2) wait material, wherein calcium hydroxide (Ca (OH)
2) again can with carbon dioxide (CO in the water
2) reaction generates the GaCO of indissoluble
3Attached on the cathode plate, form dirty matter Deng material.The method that the present invention adopts anodic-cathodic regularly to exchange automatically realizes the electrode automatic desludging, because the chlorine that anode produces can be with dirty matter dissolving with the hydrochloric acid materials such as (HCl) that the reaction back produces.
Advantage of the present invention:
1, utilize the low characteristics of hydrogen solubility, but realize first not only normal pressure operation but also can with pressurely move of air-floating apparatus, can pressurize through elevator pump during operation with pressure to enter down technology one, has saved equipment investment and energy consumption.
2, adopt twice electro-flotation, dosing after the one-level air supporting has reduced chemical feeding quantity, has saved cost.
3, the various advantages that have electro-flotation: energy consumption is low, bubble is little, the time of staying is short, powerful bactericidal action is also arranged in the oil removing oil removal, need not to add other bactericide, reduces operating cost.
4, machinery-free moving component in the container has also just avoided occurring mechanical breakdown in the container, has reduced maintenance load.
5, structure is flexible, places according to operating mode equipment and can stand and can crouch, and can make floor space only be 1/4 of the electric floating device of other secondarys when selecting vertical the placement for use.
6, because bubbles volume depends primarily on size of current, and electric current is adjustable, can feed back to control system according to the flow size that the inlet flow rate meter reads like this, thereby control system is regulated the electric current bubbles volume automatically, the realization closed loop is controlled automatically, guarantees stable effluent quality; Simultaneously can realize that pole plate does not have fouling by the regular exchange of automatic control pole plate.
7, equipment adopts the totally-enclosed design, to the environment non-secondary pollution.
