Detailed description of the invention
Fig. 1 is the structural schematic diagram of the water-oil phase flow pattern conversion equipment of one embodiment of the present invention；
Fig. 2 is the structural schematic diagram of diffusion sheet in Fig. 1.
Specific embodiment
As shown in Figure 1, the water-oil phase flow pattern conversion equipment of one embodiment of the present invention generally includes successively phase
Inlet tube 10, crossover connection 20 and outlet 30 even.
The inlet tube 10 is vertically installed with the drug-feeding tube 11 communicated with inside on tube wall, in the inside in 11 downstream of drug-feeding tube
It is provided with the diffusion sheet 12 for strengthening medicament diffusion effect.The crossover connection 20 gathers for realizing little particulate oil in grease and at biggish
Particle, inside are disposed with inclined commutator segment 21 and horizontal poly- and piece 22.The outlet 30 will be for after gathering and handling
Fluid be expelled to subsequent oil-water separation system.
At work, to it is poly- and oil water mixture entered by inlet tube 10, while by drug-feeding tube 11 by chemical demulsification medicine
Agent is discharged into inlet tube 10 and mixes with oil water mixture therein, and the chemical demulsification medicament being discharged into can under the action of diffusion sheet 12
It is distributed in the space of entire inlet tube 10 as far as possible, to be sufficiently mixed with oil water mixture.It is mixed with chemical demulsification medicament
After oil water mixture enters crossover connection 20, it can be divided into the entire space of crossover connection 20 under the action of commutator segment 21
Multilayer, and the flowing angle of each layer is to flow downwards, the oil in oil water mixture are mutually interpolymerized in flow process and simultaneously gradually
It settles, the oil droplet of final settlement realizes absorption on poly- and piece 22, and the oil of molecule gathers and at bulky grain in oil water mixture
Oil water mixture after oil is entered in the oil-water separation system of next step by flowing out in outlet 30, realizes the separation of grease.
In the present embodiment, the oil water mixture oil content of processing can be within 50%, for convenience of chemical demulsification medicine
Agent is sufficiently mixed with oil water mixture, and drug-feeding tube 11 is located at the elbow structure that one end in inlet tube 10 can be 90 degree, bending
Direction it is identical as the flow direction of oil water mixture, which can reduce influence of the oil water mixture to drug row mouth.Diffusion
Piece 12 can be the plate structure of lattices, using corresponding blocking make by chemical demulsification medicament be dispersed into it is more tiny
Particle, to sufficiently be reacted with oil water mixture.
Present embodiment is small in size, occupied area is small, simple without moving component, maintenance, which can be improved traditional oils
Laden water separation process efficiency simultaneously simplifies its process.The device mating can be used for ocean platform, onshore oil field, or even can be used for non-water
Lower oil-water separation system.
As shown in Fig. 2, in an embodiment of the invention, specific 12 structure of diffusion sheet can be two crosses and hand over
The straight panel for pitching the half-oval shaped of setting, is provided with multiple circular holes 121 in straight panel.Two straight panels are mutually perpendicular to connect by straight flange
Touching, and elliptical side is then contacted with the side wall of inlet tube 10 respectively.Circular hole 121 can use regularly arranged, 121 diameter of circular hole
It is subject to the flowing for not influencing oil water mixture.
It in an embodiment of the invention, is the mobility for making full use of oil water mixture, inlet tube 10 is being converted
The link position of 20 entrance of pipe is located at the lower part of 20 axial line of crossover connection, and outlet 30 is in the connection in 20 exit of crossover connection
Position is located at the top of 20 axial line of crossover connection.The structure can make oil water mixture in inlet tube 10, crossover connection 20 and outlet
The flow tendency being gradually increasing is formed in pipe 30, so that the oil of convenient wherein lightweight floats and gathers simultaneously, and after heavy water then declines
Layering.
In an embodiment of the invention, which has multi-disc and is spaced apart from each other in the diameter of crossover connection 20
Ground is uniformly laterally arranged, and the side of each commutator segment 21 can be with the contact aside of crossover connection 20, so that the oil water mixture entered
It can only be flowed along the channel between commutator segment 21.The inclined direction of commutator segment 21 is oblique lower section, is existed with the angle a of horizontal plane
Between 5 ° -15 °.The structure can reduce the flow velocity of oil water mixture, facilitate oil poly- simultaneously.Poly- and piece 22 be again provided with multi-disc and
It is spaced apart from each other horizontally disposed, and every poly- and piece 22 is corresponding with 21 position of a diffusion sheet respectively, which can be to avoid corresponding
Oil water mixture in channel mutually mixes, and improves the continuity during oil gathers simultaneously.In the present embodiment, 21 He of commutator segment
Poly- and piece 22 length can be identical.
Further, in an embodiment of the invention, commutator segment 21 and poly- and piece 22 between each other and with it is mutual
It changes there are certain gap between the both ends of pipe 20, specific gap size may is that commutator segment 21 and 20 import of crossover connection
Distance and poly- and piece 22 are equidistant with what crossover connection 20 exported, and the distance between commutator segment 21 and poly- and piece 22 can be it
With the half of inlet and outlet both ends distance.
In one embodiment of the present invention, the structure explanation of a specific two-phase stream conversion device is provided；
Wherein, the diameter that the diameter of inlet tube 10 is less than outlet 30 is less than the diameter of crossover connection 20, and the ratio of three can
Think 1:2:6 or so.The diameter of drug-feeding tube 11 can be the 1/3 of 10 diameter of inlet tube.Commutator segment 21 and 20 import of crossover connection it
Between distance and poly- and piece 22 and crossover connection 20 export at a distance from can be respectively the 1/18 of 20 length of crossover connection.And commutator segment 21
The distance between poly- and piece 22 is then the 1/35 of 20 length of crossover connection.
Such as: the diameter of inlet tube is 50mm；The diameter of crossover connection is 300mm；The diameter 80mm of outlet；Drug-feeding tube it is straight
Diameter is 15mm；The diameter of circular hole is 5mm on diffusion sheet；The tilted rectification leaf length of crossover connection is 300mm, totally 5 and inclination
10°；The length of gathering board is that 300mm is uniformly distributed for 5 totally；Commutator segment and poly- piece interval 20mm, at rectification apart from crossover connection into
