The energy consumption of low viscous crude Produced Liquid dehydration.2, the swirl channel in the static mixing tube of the utility model is by being fixed on static state
It mixes on inside pipe wall and is constituted along multiple swirling flow unit pieces that its axis direction interval is laid, multiple swirling flow unit pieces are mixed in static state
It closes and is helically interspersed on the internal perisporium of pipe；Since the effect of swirling flow unit piece changes oil liquid flow direction constantly, can promote
The mixing of viscous crude and thin oil substantially reduces the viscosity of oil liquid, reduces the flow resistance of oil liquid and tube wall, and it is defeated to improve viscous crude Produced Liquid
Efficiency out.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the partial structural diagram of the thin oil blending section of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the utility model, which provides, a kind of mixes the defeated device of dilute collection, the device for viscous crude Produced Liquid
Including Produced Liquid inlet tube 1, the dilute supervisor of lifting thickened oil and thin oil injection pipe 7；Wherein, the dilute supervisor of lifting thickened oil is divided into from top to bottom
Eddy flow section 2, contraction section 3, tail bone section 4, endpiece 5, water-oil separating section 6, thin oil blending section 8 and outlet section 9；Produced Liquid inlet tube
1 vertically through the eddy flow section 2 in the dilute supervisor of lifting thickened oil side wall；Center oil flow tube 10 is coaxially equipped in water-oil separating section 6, oil
Annular space is formed between water segregation section 6 and center oil flow tube 10, thin oil injection pipe 7 passes through in 6 side wall of water-oil separating section and its
Center oil flow tube 10 vertically through；It is coaxially equipped with static mixing tube 11 in thin oil blending pipe 8, also forms ring between the two
Shape space, static mixing tube 11 is interior to be equipped with swirl channel, so that oil liquid is streamed movement as spiral in static mixing tube 11, promotes not
Oil liquid with consistency mixes.
In above-described embodiment, the swirl channel in static mixing tube 11 is by being fixed on 11 inner wall of static mixing tube and edge
Multiple swirling flow unit pieces 13 that its axis direction interval is laid are constituted, and multiple swirling flow unit pieces 13 are in static mixing tube 11
It is helically interspersed on peripheral wall.
In above-described embodiment, the dilute supervisor of lifting thickened oil is divided into coaxial circular cone pipeline section and cylinder pipeline section, wherein eddy flow section 2 is received
Contracting section 3 and tail bone section 4 constitute the circular cone pipeline section of the dilute supervisor of lifting thickened oil, and caliber is gradually reduced, cutting in Produced Liquid inlet tube 1
Carry out liquid to grease and enter circular cone pipeline section to make swirling motion, realizes water-oil separating flowing；Endpiece 5, water-oil separating section 6, thin oil blending
Section 8 and outlet section 9 constitute the cylinder pipeline section of the dilute supervisor of lifting thickened oil, and caliber is consistent.
The static mixing tube in center oil flow tube 10 and thin oil blending section 8 in above-described embodiment, in water-oil separating section 6
About 11 are interconnected, and are in separation flowing (i.e. in the grease of outer layer water ring internal layer wick to guarantee the grease in outlet section 9 also
SHUNT state).
In above-described embodiment, Produced Liquid inlet tube 1 connects viscous crude Produced Liquid oil pipe, and defeated pipe is adopted in the connection of outlet section 9.
The utility model use process is as follows: viscous crude Produced Liquid with certain speed by Produced Liquid inlet tube 1 tangentially into
The eddy flow section 2 for entering the dilute supervisor of lifting thickened oil is forced to do rotary motion after encountering the wall surface of eddy flow section 2, under certain pressure differential,
Screw is formed, after the two-stage of contraction section 3 and tail bone section 4 is shunk, Produced Liquid speedup and the formation one in circular cone pipeline section
Stable centrifugal force field, since the density of water is greater than oil, according to Stokes' law, the heavy phase water in Produced Liquid is in powerful centrifugation
The inner wall of eddy flow section 2 and contraction section 3 and tail bone section 4 is thrown under the action of power, is formed spiral state and is flowed water ring, light phase oil stream
Then assemble to form wick to tube hub, realizes water-oil separating flowing；Then, water ring and wick enter cylinder pipeline section, water ring and oil
Core is introduced into current stabilization in endpiece 5, and water ring enters in the annular space between water-oil separating pipeline section 6 and center oil flow tube 10 later,
Wick enters in center oil flow tube 10；Thin oil injection pipe 7 conveys thin oil into center oil flow tube 10, and thin oil and viscous crude wick are mixed
Close and enter static mixing tube 11, it is left-handed when fluid under the action of 11 inward eddy unit piece 13 of static mixing tube, when and it is right
Rotation, flow direction constantly changes, so that thin oil is sufficiently mixed with viscous crude, lifting thickened oil is dilute, and the viscosity and flow resistance of wick reduce；
Subsequently, mix it is dilute after oil liquid flowed out from static mixing tube 11, and the annular between section 8 and static mixing tube 11 is blended from thin oil
The water ring contact of space outflow, forms the grease SHUNT state of outer layer water ring internal layer wick in outlet section 9, substantially reduces wick
Flow resistance, Produced Liquid mix it is dilute after other than in water ring the form of wick convey outward, make in Produced Liquid transmission process with tube wall
The resistance of contact greatly reduces；
During flowing, due to the density variation of grease, water can sink because density is larger, and bias occurs for water ring,
So that the water ring on pipe top is less or even pipe top does not have water, the direct contacting pipe top of oil stream, but because viscous crude and thin oil blend, oil
The viscosity of stream reduces, and reduces the flow resistance that viscous crude is contacted with wall surface, even if bias occurs for water ring, entire Produced Liquid connects with tube wall
The resistance of touching is also to greatly reduce；
Whole device will be mixed dilute drag reduction and be combined with water ring drag reduction to reduce the flow resistance between viscous crude and tube wall, improve
The delivery efficiency of viscous crude Produced Liquid, and be not required to additionally inject water, the dosage of water during the output of viscous crude Produced Liquid is saved, is reduced thick
The energy consumption of oily Produced Liquid dehydration, whole device have biggish practicability and market prospects.
The utility model is only illustrated with above-described embodiment, and structure, setting position and its connection of each component are all can
With what is be varied.It is all that individual part is carried out according to the utility model principle on the basis of technical solutions of the utility model
Improvement or equivalents, should not exclude except the protection scope of the utility model.
