Description

A kind of efficient air-floating apparatus
Technical field
The utility model relates to a kind of efficient air-floating apparatus.
Background technology
Petroleum and petrochemical sector can produce a large amount of oily(waste)waters in the production processes such as oil production, processing, crude oil refinement, and conventional oil-water separation method mainly contains: the methods such as gravity settling separation, air supporting choosing, hydrocyclone separation technology, filtering separation.These methods have relative merits and the scope of application separately, and wherein dissolved air flotation technology is due to technical maturity, applied widely, less investment, and the low grade of operation and maintenance cost has been widely used in oil, chemical industry oily water treatment.
Tradition dissolved air flotation technology, the residence time substantially between 15 minutes~30 minutes, due to overstand, causes that equipment volume is large, floor space is larger, limited its range of application, particularly facility compact type has been required more strictly to survey place (as FPSO, employing platform etc.).Next be traditional dissolved air flotation efficiency generally in 80% left and right, more and more cannot meet the requirement of high oil removal efficiency.
Hydrocyclone is that dependence oil droplet and sewage density difference are next separated, and when oil droplet density more and more approaches sewage density, droplet diameter has in less situation, and swirler deoiling effect can decline to a great extent, and cannot meet oily water treatment requirement; Hydrocyclone is had relatively high expectations, for low pressure operating mode, need be increased power-equipment inlet pressure simultaneously, and increase investment and use cost, be exactly that the anti-fluctuation of hydrocyclone is little again, adaptability is poor.
Utility model content
The purpose of this utility model is to provide a kind of structure compacter for the deficiencies in the prior art, when having reduced equipment volume and floor space, obtain better oil removing and except the cyclone gas flotation separator of suspended particulate effect, be applicable to the Application Areass such as various sump oil waters are separated, suspended substance is separated, be specially adapted to the processing of petroleum chemical industry oily(waste)water.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of efficient air-floating apparatus, the tank body that comprises sealing, described tank body top is provided with sump oil outlet, bottom is provided with processing water out, in described tank body, be provided with an inner core, described inner core top end opening, described inner tank theca is provided with an ejector nozzle in tangential direction, ejector nozzle is communicated with a sewage inlet pipe, and the other end of sewage inlet pipe is provided with topping-up pump.
Preferably, the water out top, bottom of described inner core is provided with a ring baffle, between described baffle plate and described inner tank wall, is provided with gap.
Preferably, described inner core comprises the top section of falling loudspeaker, middle column body segment and bottom cone section from top to bottom successively, and the lower end of described inner core is provided with sewage draining exit, and described sewage draining exit is in communication with the outside.
Preferably, described tank body inner side is provided with annular oil trap near the position of described inner core top end opening, and tank wall is provided with oil discharge outlet in the position of corresponding oil trap.
Preferably, sewage inlet pipe is provided with a mixing tank, and mixing tank is also communicated with a mixed solution sewage inlet pipe.
Owing to adopting said structure, this patent tool has the following advantages:
1, tank body is divided into an inner compartment and cylinder exterior domain by inner core, refinement swirler interior flow field, avoided oil droplet and the interference of processing between water, make more reasonable at this device interior flow field tissue of eddy flow, space availability ratio is higher, and structure of container is more compact, and oil removal efficiency is higher; Set up ejector nozzle and topping-up pump, strengthened the pressure of sewage water outlet, made the centrifugal force of eddy flow larger, separating effect is better.
2, the inwall of sewage inlet and described inner core is tangent, thereby can produce larger centrifugal force and more stable eddy flow, strengthen between bubble and oil droplet and acted on, accelerate the gathering of oil droplet and bubble, make separation efficiency higher, thereby can obtain better oil removing and desanding effect.
3, the bottom of inner core, processes water out top one ring baffle is installed, and plays mitigation current, makes water out current more evenly mild, prevents out that saliva carries silt, reduces and oleaginousness in saliva, improves separation efficiency.
4, inner core bottom is provided with sewage draining exit, and the silt depositing all the time in bottom rotation, forms fluidization eddy flow state in inner core, and silt is not easy in bottom deposition, is not easy to cause device bottom silt to harden and pipeline obstruction.
In sum, this device interior flow field is organized more rationally, the centrifugal intensity of generation is larger, structure is more compact, can obtain better oil removing and desanding effect.

Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As described in Figure 1, mainly by tank body 1, sewage inlet pipe 2, inner core 3, ring baffle 4, sump oil outlet 6, processing water out 7, sewage draining exit 5, gas-liquid mixed sewage inlet pipe 111, mixing tank 112, topping-up pump 114 etc., formed.Wherein tank body 1 is divided into an inner compartment 8 and cylinder exterior domain 9 by inner core 3.Described inner core 3 and tank body 1 concentric setting, inner core 3 is comprised of column body segment 31, the top section of falling loudspeaker 32 and bottom cone section 33 in the middle of inner core.
As described in Figure 2, as a kind of mode of the present utility model, described tank body inner side is provided with annular oil trap 11 near the position of described inner core upper end open, and the separated gas producing is discharged from sump oil outlet 6, the separated oil producing enters oil trap 11, from oil discharge outlet 10, discharges.
As described in Figure 3, as another kind of mode of the present utility model, described inner core 3 is round shape, and the bottom of the bottom of described inner core 3 and described tank body 1 is connected to an integral body.
As shown in Figure 4, inner core 3 outer walls are provided with an ejector nozzle 113 in tangential direction, and ejector nozzle is communicated with sewage inlet pipe, and ejector nozzle also can arrange a plurality of in tangential direction.
Principle of work: oily(waste)water is under the pump pressure of topping-up pump 114, after the gas and liquid mixture that carries a large amount of microbubbles entering with mixed solution sewage inlet pipe 111 through mixing tank 112 mixes, by sewage inlet pipe 2 and ejector nozzle 113, from the water inlet of inner core 3, enter into the inner core region 8 of inner core 3, the mode entering is for tangentially entering, thereby form eddy flow in inner core 3, microbubble carries oil droplet progressively to inner core region 8 intermediary movementses and rise to liquid-gas interface, Bubble, oil droplet forms scum silica frost and discharges through sump oil outlet 6.The hydraucone 32 that falls that meanwhile sewage after flotation covers inner core 3 moves downward cylinder exterior domain 9, walks around after baffle plate 4, and treated water out 7 is discharged.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in technical solutions of the utility model protection domain.
