Abstract
The utility model provides an annular sectional plug-flow coalescence structure for a vertical tank. The coalescence structure comprises an arc coalescence tank fixed in the inner wall of the vertical tank and coalescence packing arranged in the coalescence tank, wherein one end of the coalescence tank is a water inlet end, while the other end of the coalescence tank is a water outlet end; a water distribution port is formed in the water inlet end, and a water distribution pipe is connected to the lower part of the water distribution port; a water outlet is formed in the water outlet end, and a water inlet pipe is connected to the lower part of the water outlet; an oil collection port is formed in the middle of the coalescence tank, and an oil collection pipe is connected to the lower part of the oil collection pipe; the water distribution pipe, the oil collection pipe and the water outlet pipe are vertically downward extend out of the bottom of the coalescence tank; the coalescence packing is arranged in a two or more sections plug flow manner in groups, so that sewage can be distributed once again in a larger space between every two groups. According to the annular sectional plug-flow coalescence structure, most dispersed oil and emulsified oil in water can be guaranteed to perform coalescence and form large oil beads, so that floating separation can be accelerated, the treatment efficiency and treatment effect of the vertical tank can be further improved, and the recycling rate of crude oil can be improved.
Description
Technical field
The utility model relates to the vertical tank internal structure for oil field produced water treatment, specifically a kind of vertical tank annular segments pulling flow type conglomerate structures.
Background technology
Vertical sewage treatment pot is the produced water disposal equipment that relies on gravity settling effect to carry out oily water separation, has the advantages such as simple in structure, easy to operate, stable, maintenance cost is low, has carried out widespread use in oil field.The shortcomings such as it is bulky that but general vertical sewage treatment pot has, and working efficiency is not high.Coalescent deoiling technology is also a kind of physical chemistry technology that separates oily(waste)water, and the object of coalescent processing is mainly dispersed oil and the stable oil in water emulsion of nonsurfactant in water.When oily(waste)water is by coalescence material, due to the affinity interaction of coalescence material to oil droplet in water, make it mutually coalescent, form the larger oil droplet of diameter, under the impulse action of buoyancy of water and current, come off, buoyance lift and reach the object of oil removing.Through coalescent sewage after treatment, its oleaginousness and oil property do not change, but more easily with gravitational separation process, oil are removed, and can improve oily water separation efficiency.Therefore, if coalescent deoiling technique is combined with gravity settling technique, in vertical tank, introduce coalescent pack, can further improve the separation efficiency of vertical tank, improve crude oil recovery rate.Meanwhile, the arrangement of coalescent pack in vertical tank also can affect the treatment effect of whole plant to a great extent.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical tank annular segments pulling flow type conglomerate structures, further improves processing efficiency and the treatment effect of vertical sewage treatment pot.
The purpose of this utility model can be achieved by the following technical measures:
This vertical tank annular segments pulling flow type conglomerate structures comprises the coalescent groove of the arc being fixed on vertical tank inwall and is arranged in the coalescent pack in coalescent groove, described coalescent groove wherein one end is feed-water end, the other end is water side, be provided with water-distributing gap at feed-water end, this water-distributing gap bottom connects water distributing pipe, sets out the mouth of a river in water side, and this water outlet bottom connects rising pipe, the middle part of described coalescent groove is provided with receiving port, and this receiving port bottom connects collection tube.
The arc angle of described coalescent groove is adjusted according to influent quality situation, and corresponding central angle is 45 °-135 °.
Described water distributing pipe, collection tube and rising pipe all stretch out outside coalescent groove bottom vertically downward.
Described receiving port is horn-like or groove shape structure.
Divide into groups two or more pulling flow types of described coalescent pack are arranged, make the larger space of sewage between every two groups re-start water distribution.
The utlity model has following beneficial effect:
Coalescent deoiling technique is combined with gravity settling technique, compared with the produced water disposal equipment that carries out oily water separation with traditional dependence gravity settling effect, can guarantee most dispersed oil and oil in water emulsion generation coalescence in water, form large oil droplet, thereby accelerating floating separates, thereby further improve processing efficiency and the treatment effect of vertical tank, improve crude oil recovery rate.

In figure: 1-vertical tank; The coalescent groove of 2-; 3-water-distributing gap; 4-water distributing pipe; 5-receiving port; 6-collection tube; 7-water outlet; 8-rising pipe.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
As shown in Figure 1-2, this vertical tank annular segments pulling flow type conglomerate structures comprises that the coalescent groove 2 of arc and the polycomponent section that are fixed on vertical tank 1 inside circumference tank skin are arranged in the coalescent pack composition in coalescent groove, it is characterized in that being provided with water-distributing gap 3 at the feed-water end of coalescent groove, water-distributing gap bottom connects water distributing pipe 4, middle part is provided with receiving port 5, receiving port bottom receives oil pipe 6, and water side is provided with water outlet 7, water outlet bottom connected water outlet pipe 8.The arc angle of described coalescent groove is adjusted according to influent quality situation, and corresponding central angle is 45 ° ~ 135 °.Described water distributing pipe, collection tube and rising pipe all stretch out outside coalescent groove bottom vertically downward.Described receiving port is horn-like or groove shape structure.
Oil field extracted water enters coalescent groove 2 by water distributing pipe 4 and water-distributing gap 3, by the coalescent pack of two or more pulling flow type packet layout, be convenient to fluidised form adjustment and oily water separation successively, make most dispersed oil and oil in water emulsion generation coalescence in water, form large oil droplet, separate thereby accelerate floating.Coalescent recovered water after treatment is discharged coalescent groove 2 by water outlet 7 and rising pipe 8.The oil slick of coalescent formation is discharged vertical tank 1 by receiving port 5 and collection tube 6.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
