[0016] Beneficial effects:

[0017] The utility model provides an extraction separator, comprising a separation core tube; the separation core tube has a separation spinal canal, a liquid inlet component and a liquid outlet pipe; the separation spinal canal is a conical structure extending in a vertical direction, and the separation spinal canal has a first end and a second end, and the separation spinal canal gradually becomes thinner from the first end to the second end; the liquid inlet component is arranged on one side of the separation spinal canal and is connected to the separation spinal canal, and the liquid inlet component discharges liquid into the separation spinal canal in a horizontal direction and in a direction tangent to the inner wall of the separation spinal canal; the liquid outlet pipe comprises a light liquid pipe and a heavy liquid pipe, the light liquid pipe is arranged at the first end, and the heavy liquid pipe is arranged at the second end, and both the light liquid pipe and the heavy liquid pipe are connected to the separation spinal canal.

Since the angle of the mixed liquid when it is discharged into the separation vertebral canal is tangent to the inner wall of the separation vertebral canal and is discharged in a horizontal direction, after the mixed liquid enters the separation vertebral canal, it rotates and flows around the axial direction of the separation vertebral canal along the inner wall of the separation vertebral canal, so that the mixed liquid forms a vortex in the separation vertebral canal.

[0031] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] See Figures 1 to 3 The extraction separator provided in this embodiment includes a separation core tube 100.

[0033] The separation core tube 100 includes a separation spinal canal 110, a liquid inlet assembly 200, and a liquid outlet pipe 300. The separation spinal canal 110 is a conical structure extending in a vertical direction, and the separation spinal canal 110 has a first end and a second end, and the separation spinal canal 110 gradually tapers from the first end to the second end. The liquid inlet assembly 200 is arranged on one side of the separation spinal canal 110 and is connected to the separation spinal canal 110. The liquid inlet assembly 200 discharges liquid into the separation spinal canal 110 in a horizontal direction and tangential to the inner wall of the separation spinal canal 110. The liquid outlet pipe 300 includes a light liquid pipe 310 and a heavy liquid pipe 320. The light liquid pipe 310 is arranged at the first end, and the heavy liquid pipe 320 is arranged at the second end. Both the light liquid pipe 310 and the heavy liquid pipe 320 are connected to the separation spinal canal 110.

[0034] Specifically, the liquid inlet assembly 200 in this embodiment discharges the mixed liquid into the separation canal 110 along the inner wall of the separation canal 110. Since the mixed liquid is discharged into the separation canal 110 at an angle tangential to the inner wall of the separation canal 110 and is discharged horizontally, after entering the separation canal 110, the mixed liquid rotates along the inner wall of the separation canal 110 and around the axial direction of the separation canal 110, forming a vortex in the separation canal 110. This vortex effect helps to separate components of different densities under the action of centrifugal force.

[0035] Furthermore, in this embodiment, the extractor separator is positioned with the first end at the top and the second end at the bottom. Centrifugal force accelerates the flow of the lighter liquid, which has a lower density, and moves upward through the spinal canal, ultimately exiting from the lighter liquid pipe 310. The heavier liquid, which has a higher density, flows downward and ultimately exits from the heavier liquid pipe 320, thereby achieving effective material separation. The extractor separator provided in this embodiment has a simple structure, requires relatively low operating conditions, and does not require excessive energy consumption.

[0036] In this embodiment, the liquid inlet assembly 200 includes a spiral channel 210. The spiral channel 210 is located within the separation spinal canal 110, surrounds the axis of the separation spinal canal 110, and extends along the axial direction of the conical structure. A liquid inlet 211 is provided at one end of the spiral channel 210, and the other end is located within the separation spinal canal 110, with the liquid outlet direction tangent to the inner wall of the spiral channel 210. The liquid inlet direction of the liquid inlet 211 is tangent to the side wall of the spiral channel 210.

[0037] Specifically, the spiral channel 210 can increase the flow rate of the vortex formed by the mixed liquid, thereby increasing the rotation speed of the mixed liquid in the separation spinal canal 110, strengthening the centrifugal force of the mixed liquid, and facilitating the subsequent separation of light liquid and heavy liquid.

[0038] In this embodiment, there are two liquid inlets 211 , and the two liquid inlets 211 are staggered.

[0039] See Figure 2 In this embodiment, the two liquid inlets 211 have opposite liquid inlet directions and are mirror-imaged on either side of a diameter separating the spinal canal 110. With this structure, the liquid discharged from the two liquid inlets 211 into the spiral channel 210 flows in the same direction, further increasing the rotational speed of the mixed liquid in the spiral channel 210.

[0040] Moreover, when the two liquid inlets 211 are discharged separately, the light phase and the heavy phase in the mixed liquid have different flow rates after entering the spiral channel 210 due to the different densities. The different flow rates of each flow layer will inevitably produce strong turbulent vortices. The existence of vortices improves the internal circulation flow of the droplets, increases the mass transfer coefficient, and creates a good fluid mechanics environment for mass transfer separation.

[0041] It's important to note that the "turbulent mixing principle" in fluid dynamics refers to the mixing mechanism between different components of a fluid when the fluid is in a turbulent state. Turbulence is an irregular, chaotic flow state, as opposed to laminar flow (smooth, orderly flow). In turbulent flow, matter or energy within the fluid can rapidly exchange and mix between different regions, and this mixing process is much faster than mixing under laminar conditions.

[0042] In this embodiment, the turbulent mixing principle is combined with centrifugal separation. The spiral channel 210 increases the swirling flow rate of the mixed liquid and ensures the stability of the mixed liquid during rotation. At the same time, the increase in the swirling flow rate of the mixed liquid increases the centrifugal force, which ensures the mass transfer effect while also achieving the effect of efficient separation.

[0043] Because the centrifugal force within the separation cone is typically hundreds to thousands of times greater than gravity, the phase separation rate is greater than the gravitational settling rate. Upon entering the separation cone, the light phase is sheared into small droplets, which migrate toward the central axis due to the centrifugal force. The heavy phase, with its high density, migrates toward the inner wall of the cone under the influence of the centrifugal force. Furthermore, the separation cone is a dynamically balanced flow field. Due to the shear force, droplets continuously break and coalesce within the cone. This continuous breakage and coalescence increases the surface renewal rate, improves the mass transfer coefficient, and refines the droplet size. This droplet coalescence also enhances the phase separation process to a certain extent.

[0044] In addition, the extraction separator provided in this embodiment is a static device with no rotating parts inside, a simple structure, and a small size. It can be used alone or in series or parallel. It has low operating and maintenance costs, a small pressure drop, and does not require an additional power device for rotation or stirring. The equipment has a long service life cycle and is simple and convenient to install, operate, and maintain.

[0045] It should be noted that the spiral channel 210 in this embodiment includes a cylindrical space located at the top of the separation cone and a spiral blade 223. The outer diameter of the spiral blade 223 is the same as the sidewall of the cylindrical space, and the spiral blade 223 is arranged around the lightweight liquid tube 310. The inner ring of the spiral blade 223 is in contact with the outer wall of the lightweight liquid tube 310, and the outer ring is in contact with the sidewall of the cylindrical space, forming the spiral channel 210. Both liquid inlets 211 are located on the sidewall of the cylindrical space.

[0046] In this embodiment, the liquid inlet assembly 200 further includes an outer cylinder 220. The outer cylinder 220 is sleeved on the outside of the separation core tube 100, and the outer cylinder 220 is spaced apart from the separation core tube 100 and forms a liquid inlet channel 221 on the outside of the separation core tube 100. The liquid inlet channel 221 is connected to the liquid inlet 211 of the spiral channel 210.

[0047] Specifically, the inner wall of the outer cylinder 220 and the inner wall of the separation core tube 100 in this embodiment are combined to form a liquid inlet channel 221 . The mixed liquid is discharged into the spiral channel 210 through the liquid inlet 211 and discharged into the separation cone.

[0048] In this embodiment, the outer cylinder 220 has a liquid injection port. A diverter cone 114 is provided on the outer wall of the separation spinal canal 110. The diverter cone 114 is located in the liquid inlet channel 221 with the top of the cone facing the liquid injection port.

[0049] The diversion cone 114 can divert the mixed liquid injected into the liquid injection port, so that the mixed liquid entering the liquid inlet channel 221 can be smoothly diverted and move toward the spiral channel 210, avoiding the mixed liquid being blocked by a plane when flowing into the liquid inlet channel 221 and reducing the flow rate.

[0050] In this embodiment, the liquid injection port is provided at the bottom of the outer cylinder 220. The diverter vertebral body 114 is provided at the outer bottom wall of the separated spinal canal 110.

[0051] Specifically, the liquid injection port in this embodiment is at the bottom of the outer cylinder 220, the diverter cone 114 is inside the outer cylinder 220, and the cone tip of the diverter cone 114 faces the liquid injection port. After the mixed liquid is injected from the liquid injection port, the diverter cone 114 diverts the liquid, and the liquid flows toward the liquid inlet channel 221 above.

[0052] In this embodiment, the cone angle of the diverter cone 114 is greater than or equal to 125° and less than or equal to 135°.

[0053] Specifically, the cone angle of the diverter cone 114 in this embodiment is 125°. It can be seen that if the cone angle is too small, too much space will be occupied, and if the angle is too large, the diverter effect will be poor. When the cone angle is greater than or equal to 125° and less than or equal to 135°, smooth diversion can be achieved and less space is occupied.

[0054] In this embodiment, a first through-hole is provided at the top of the outer cylinder 220, and a second through-hole is provided on the bottom sidewall of the outer cylinder 220. The light liquid pipe 310 is disposed within the first through-hole, with the outer wall of the light liquid pipe 310 abutting and sealing against the first through-hole. The heavy liquid pipe 320 extends horizontally and is disposed within the second through-hole, with the outer wall of the heavy liquid pipe 320 abutting and sealing against the second through-hole.

[0055] For details, please refer again to Figure 1 In this embodiment, the outer cylinder 220 and the separation core tube 100 form a sleeve structure. The light liquid pipe 310 extends from the outer cylinder 220 through the first through-hole to discharge the light liquid. Correspondingly, the heavy liquid pipe 320 extends from the outer cylinder 220 through the second through-hole to discharge the heavy liquid. Sealing is performed between the first through-hole and the light liquid pipe 310, and between the second through-hole and the heavy liquid pipe 320 to ensure the tightness of the liquid inlet channel 221.

[0056] In this embodiment, the separation core tube 100 comprises a large conical section 111, a small conical section 112, and a tail section 113, which are connected in a vertical sequence. The angle of the large conical section 111 is greater than that of the small conical section 112. The liquid inlet assembly 200 is connected to the top of the large conical section 111. The tail section 113 is a circular tube, and the heavy liquid pipe 320 is located on one side of the tail section 113 and is connected to the tail section 113.

[0057] Specifically, the length of the large conical section 111 is 2 to 2.8 times the length of the cylindrical space (the vertical linear distance of the spiral channel 210). This large conical section can significantly increase the rotational speed of the fluid. Furthermore, the angle of the small conical section 112 is determined by the values ​​of the core tube large conical section and the tail tube section 113. The length of the small conical section 112 is equal to that of the core tube large conical section. The small conical section 112 can promote the separation of the two phases of the fluid. Specifically, the gradually decreasing taper allows liquids of different densities to further separate under the action of centrifugal force.

[0058] The inner diameter of tail pipe section 113 is 0.3 to 0.35 times the maximum diameter of large conical section 111. The length of tail pipe section 113 should be designed based on the actual requirements for cyclonic separation efficiency. The size of tail pipe section 113 has a significant impact on separation performance. Furthermore, the length of tail pipe section 113 should be optimized based on the actual separation efficiency requirements.

[0059] The cone angle of the great vertebral segment 111 is greater than or equal to 6° and less than or equal to 8°.

[0060] Specifically, the cone angle of the large cone section 111 in this embodiment is 8°. Changing the large cone angle will affect the rotation speed of the fluid, thereby affecting the separation effect. Correspondingly, the larger the cone angle, the faster the rotation speed of the mixed liquid.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
