Description

Technical Field

[0001] This application relates to the field of extraction technology, and in particular to a high-efficiency tank extraction device. Background Technology

[0002] Extraction is an important separation and purification method with wide applications in chemical, pharmaceutical, food, and environmental protection fields. Extraction is based on the partitioning behavior of substances between two phases (usually a liquid phase). By selecting appropriate solvents and operating conditions, the target substance can be separated and purified. Common extraction methods include liquid-liquid extraction, solid-phase extraction, and supercritical fluid extraction. Among these, liquid-liquid extraction is the most commonly used method, achieving separation and purification through the difference in interaction forces between the solvent and the extracted substance.

[0003] Tank extraction is a type of step-by-step contact extraction equipment that can be used to achieve two-phase separation. However, tank extraction devices in related technologies are not only inefficient and occupy a large area, but also require a high amount of extractant, resulting in high initial investment and subsequent operating costs. Utility Model Content

[0004] To address the problems of existing technologies, this application provides a high-efficiency tank extraction device, which at least solves the problems of low efficiency, large footprint, and high extractant consumption in related technologies, resulting in high initial investment and subsequent operating costs.

[0005] A high-efficiency tank-type extraction device is provided, comprising: a mixing chamber and a clarification chamber, wherein a first vertical partition is provided in the clarification chamber, the first vertical partition dividing the clarification chamber into a liquid distribution zone and a phase separation zone, and the liquid distribution zone is connected to the mixed phase outlet of the mixing chamber;

[0006] Multiple liquid distribution pipes are arranged horizontally at the bottom of the phase separation zone. One end of each liquid distribution pipe is connected to the liquid distribution zone through the first vertical partition, and the other end is blocked and extends away from the first vertical partition.

[0007] A phase separation inclined plate and an oil phase overflow weir are provided in the phase separation zone. The phase separation inclined plate is located above the plurality of liquid distribution pipes, and the oil phase overflow weir is provided on the phase separation inclined plate.

[0010] In some exemplary embodiments, the angle between the phase-splitting ramp and the horizontal direction is 20° to 80°.

[0011] In some exemplary embodiments, the number of phase-splitting ramps is multiple, and the multiple phase-splitting ramps are spaced apart.

[0012] In some exemplary embodiments, the cross-sectional form of the plurality of phase-separating inclined plates is one or a combination of honeycomb, tubular or plate-shaped.

[0013] In some exemplary embodiments, the mixing chamber includes a mixing tank and a stirring assembly, with the mixed phase outlet located near the top of the mixing tank, and the stirring assembly located inside the mixing tank.

[0014] In some exemplary embodiments, the phase separation zone is provided with an oil phase outlet, a water phase outlet and a water phase reflux outlet at one end away from the liquid distribution zone, and a reflux inlet is provided on the mixing tank, and the water phase reflux outlet is connected to the reflux inlet through a reflux pipe;

[0015] A horizontal partition is provided between the bottom of the stirring assembly and the bottom wall of the mixing tank. A reflux suction hole is provided on the horizontal partition, and the reflux inlet is located between the horizontal partition and the bottom wall of the mixing tank.

[0016] In some exemplary embodiments, the phase separation zone is provided with a second vertical partition at one end away from the liquid distribution zone. The second vertical partition has a gap between itself and the bottom wall of the phase separation zone for forming a water passage hole. The second vertical partition is used to form a water outlet channel communicating with the water passage hole at the end of the phase separation zone. The water phase outlet and the water phase return outlet are located on the water outlet channel.

[0017] In some exemplary embodiments, a perforated plate is horizontally arranged in the water outlet channel, and the water phase outlet pipe and the water phase return pipe are respectively threaded through the perforated plate and connected to the water phase outlet and the water phase return outlet.

[0018] The high-efficiency tank-type extraction device of this application embodiment includes a mixing chamber and a clarification chamber. The clarification chamber is provided with a first vertical partition, which divides the clarification chamber into a liquid distribution zone and a phase separation zone.

One end of each liquid distribution pipe is connected to the liquid distribution zone through the first vertical partition, and the other end is sealed and extends away from the first vertical partition. A phase separation inclined plate and an oil phase overflow weir are provided in the phase separation zone. The phase separation inclined plate is located above the multiple liquid distribution pipes, and the oil phase overflow weir is located on the phase separation inclined plate. Because the above extraction device, through the cooperation of the liquid distribution zone and the liquid distribution pipes, allows the mixed phase to be more evenly distributed to the phase separation zone, the phase separation inclined plate in the phase separation zone is fully utilized to achieve more efficient oil-water separation. This ensures efficient phase separation while achieving a smaller surface area and volume clarification tank, thereby reducing the footprint of the extraction device and the amount of extractant used, significantly reducing both the initial investment and subsequent operating costs of the extraction device.

[0031] The following combination Figures 1-4This application introduces a high-efficiency tank extraction device according to embodiments of the present application. It is understood that the high-efficiency tank extraction device shown in the accompanying drawings is merely one specific embodiment of the technical solution in this application, and the high-efficiency tank extraction device in this application may include fewer or more structural features, and is not limited to the device structure described in the accompanying drawings.

[0032] See Figures 1-4 The high-efficiency tank extraction device 100 of this application embodiment includes a mixing chamber 1 and a clarification chamber 2. The mixing chamber 1 is used for the mixing and mass transfer reaction of the feed liquid and the extractant. The mixing and mass transfer reaction can be any one of the extraction reaction occurring in the extraction section, the back-extraction and displacement reaction occurring in the washing section, and the back-extraction reaction occurring in the back-extraction section. Subsequently, the mixed phase in the mixing chamber 1 enters the clarification chamber 2, and the oil phase and water phase are naturally separated under the action of gravity. Finally, they enter different outlets to complete the extraction process.

[0033] The mixing chamber 1 has an oil phase inlet 1a, a feed inlet 1b, and a mixed phase outlet 11. The oil phase inlet 1a is used to input the organic solution, and the feed inlet 1b is used to input the feed liquid. The feed liquid can be different at different stages of extraction and can be an extract, a back-extraction liquid, or a washing liquid. The mixed phase outlet 11 is used to output the mixed liquid after mass transfer. In a specific implementation, the oil phase inlet 1a can be located near the bottom of the mixing chamber 1, and the feed inlet 1b and the mixed phase outlet 11 can be located near the top of the mixing chamber 1, so that the organic solution and the feed liquid form counter-current flow during the mixing and mass transfer process, thereby improving the mixing and mass transfer effect.

[0034] In some exemplary implementations, such as Figures 1-4 As shown, the mixing chamber 1 may include a mixing tank 12 and a stirring assembly 13. The mixed phase outlet 11 is located near the top of the mixing tank 12, and the stirring assembly 13 is located inside the mixing tank 12. The raw material inlet 1b is located near the top of the mixing tank 12, and the oil phase inlet 1a is located near the bottom of the mixing tank 12. For example, the stirring assembly 13 is a stirring blade mounted on one end of a drive shaft. The other end of the drive shaft is connected to a motor M located outside the mixing tank 12, through which power is provided.

[0035] In this embodiment, a first vertical partition 3 is provided in the clarification chamber 2, which divides the clarification chamber 2 into a liquid distribution zone 21 and a phase separation zone 22. The liquid distribution zone 21 is connected to the mixed phase outlet 11 of the mixing chamber 1. A plurality of liquid distribution pipes 4 are arranged horizontally at the bottom of the phase separation zone 22. One end of the plurality of liquid distribution pipes 4 is connected to the liquid distribution zone 21 through the first vertical partition 3, and the other end is blocked and extends away from the first vertical partition 3. Thus, the mixed liquid output from the mixed phase outlet 11 first enters the liquid distribution zone 21 of the clarification chamber 2, and is distributed to the phase separation zone 22 for oil-water separation through the plurality of liquid distribution pipes 4 connected to the liquid distribution zone 21. This allows each liquid distribution pipe 4 to have a uniform amount of liquid, and the mixed liquid can be more evenly distributed to the phase separation zone 22, which is beneficial to improving the oil-water separation effect.

[0036] In specific implementation, the first vertical baffle 3 can be set close to the beginning of the clarifier 1, so that the space of the liquid distribution zone 21 is smaller than the space of the phase separation zone 22, so as to achieve more uniform distribution of the mixture while ensuring the oil-water separation effect. The beginning of the clarifier 1 refers to the end where the mixture enters the clarifier 1. Figures 1-4 The left end of the central clarification chamber 1 is the head end.

[0037] Multiple liquid distribution pipes 4 are arranged horizontally at intervals, and the intervals between adjacent liquid distribution pipes 4 can be the same or different. The extension lengths of the multiple liquid distribution pipes 4 can be the same or different. Mounting holes (not shown in the figure) that mate with the multiple liquid distribution pipes 4 can be opened on the first vertical partition 3, and each liquid distribution pipe 4 passes through the mating mounting holes on the first vertical partition 3.

[0038] For example, there is a gap between the outer wall of the multiple liquid distribution pipes 4 and the bottom wall of the phase separation zone 22. Each liquid distribution pipe has multiple liquid distribution holes (not shown in the figure) on the side facing the bottom wall, so that the mixture entering the liquid distribution pipe 22 from the liquid distribution zone 21 flows out through the multiple liquid distribution holes on each liquid distribution pipe 22, which helps to distribute the mixture more evenly in the space of the phase separation zone 22. In specific implementations, the size of the multiple liquid distribution holes on each liquid distribution pipe can be the same or different. For example, each liquid distribution pipe 4 can have two rows of liquid distribution holes horizontally distributed. The diameter of the liquid distribution holes can be 50-100 nm, and the spacing between adjacent liquid distribution holes in the same row can be 200-500 nm.

[0039] The high-efficiency tank extraction device of this application embodiment also includes a phase-separating inclined plate 5 and an oil phase overflow weir 6 disposed in the phase-separating zone 22. The phase-separating inclined plate 5 is located above the plurality of liquid distribution pipes 4, and the oil phase overflow weir 6 is disposed above the phase-separating inclined plate 5. The oil phase overflow weir 6 can be used to collect the oil phase. When the mixture comes out from the liquid distribution pipes 4, most of the aqueous phase no longer rises. Individual water droplets rise into the phase-separating inclined plate 5, separate from the oil phase, and gradually sink to the bottom surface of the phase-separating inclined plate 5 before flowing down the inclined surface of the phase-separating inclined plate 5, thus achieving oil-water separation.

[0040] The high-efficiency tank-type extraction device of this application divides the clarification chamber into a liquid distribution zone and a phase separation zone through a first vertical partition. The combination of the liquid distribution zone and the water distribution pipe allows the mixed phase to be more evenly distributed to the phase separation zone. This fully utilizes the phase separation inclined plate in the phase separation zone to reduce the movement path of the water and oil phases, achieving more efficient oil-water separation and increasing the surface load of the clarification chamber. As a result, while ensuring efficient phase separation, a clarification chamber with a smaller surface area and volume can be achieved. Compared with the prior art, the surface area and volume of the clarification chamber can be reduced by half, thereby reducing the footprint of the extraction device and the amount of extractant used, which greatly reduces the initial investment and subsequent operating costs of the extraction device.

[0041] In some exemplary embodiments, the extraction apparatus 100 may further include a mixed phase discharge channel 7, and the liquid distribution area 21 is provided with a mixed phase inlet 21a on the side near the mixed phase outlet 11. The first end of the mixed phase discharge channel 7 is connected to the mixed phase outlet 11, and the second end is connected to the mixed phase inlet 21a. The flow space within the mixed phase discharge channel 7 gradually expands from its first end to its second end. Figure 1 As shown, this allows the mixture entering the distribution zone 21 to be more uniform in the horizontal direction, which helps to improve the uniformity of the mixture distribution to each distribution pipe 4, thereby improving the uniformity of the mixture distribution in the phase separation zone 22 and improving the oil-water separation effect.

[0042] In some exemplary embodiments, the angle between the phase-separating inclined plate 5 and the horizontal direction is 20° to 80°, preferably 60°. There are multiple phase-separating inclined plates 5, which are arranged sequentially at intervals along the liquid flow direction.

[0043] In specific implementation, the phase-separating inclined plate 5 can be tilted towards the first vertical partition plate 3 so that the tilting direction of the phase-separating inclined plate 5 is opposite to the liquid flow direction. This allows the aqueous phase sliding down the phase-separating inclined plate 5 to flow in the direction of water phase discharge, which is beneficial for improving the oil-water separation effect. For example, the spacing between adjacent phase-separating inclined plates 5 can be the same or different, and the angle between adjacent phase-separating inclined plates 5 and the horizontal direction can be the same or different. Preferably, the spacing between adjacent phase-separating inclined plates 5 is the same, and the angle between adjacent phase-separating inclined plates 5 and the horizontal direction is the same.

[0044] In practical applications, the phase separation zone 22 can also be provided with an inclined plate support (not shown in the figure) for fixing the phase separation inclined plate 5 to the phase separation zone 22. The inclined plate support can be a pipe or a steel section.

[0045] For example, the cross-sectional shape of the multiple phase-separating inclined plates 5 can be honeycomb, tubular, or plate-shaped, or a combination of these. The tubular phase-separating inclined plates can be composed of multiple arranged tubes, which can be fixed together by welding, with the interior of each tube serving as a liquid flow channel. The plate-shaped phase-separating inclined plates can be composed of two spaced-apart solid plates, with the space between the two solid plates serving as a liquid flow channel.

[0046] Specifically, the forms of the different phase-separating ramps 5 can be the same or different. For example, the phase-separating ramps 5 near the end of the phase-separating region 22 can be in a plate-like form, while the remaining phase-separating ramps 5 can be in a honeycomb-like form. Alternatively, the remaining middle phase-separating ramps can be in a honeycomb-like form, while the phase-separating ramps 5 near the front of the phase-separating region 22 can still be in a plate-like form. The form of a single phase-separating ramp 5 can be any of the above forms, or a combination of two or three of the above forms.

[0047] For example, the phase separation zone 22 can be vertically arranged with two or more layers of the aforementioned multiple phase separation inclined plates 5, with intervals between adjacent layers. The inclination directions of adjacent phase separation inclined plates 5 can be opposite, which can increase the disturbance of rising droplets and improve the oil-water separation effect. Figure 5 As shown, it includes a first layer and a second layer, with a gap between the first layer and the second layer. The inclination direction of the multiple phase-separating plates 5 in the first layer is opposite to the liquid flow direction, while the inclination direction of the multiple phase-separating plates 5 in the second layer is the same as the liquid flow direction.

[0048] In some exemplary implementations, such as Figures 1-4As shown, the phase separation zone 22 is provided with an oil phase outlet 22a, a water phase outlet 22b and a water phase reflux outlet 22c at the end away from the liquid distribution zone 21. The mixing tank 12 is provided with a reflux inlet 12a. The oil phase outlet 22a is used to discharge the oil phase collected by the oil phase overflow weir 6. The oil phase can be transported to the next mixing chamber or the oil phase intermediate tank. Aqueous phase reflux outlet 22c is used for reflux of a portion of the aqueous phase, and aqueous phase outlet 22b is used to discharge the remaining aqueous phase. Aqueous phase reflux outlet 22c is connected to a reflux pipe 8, which communicates with reflux inlet 12a on the mixing tank 12. A horizontal baffle 9 is provided between the bottom of the stirring assembly 13 and the bottom wall of the mixing tank 12. A reflux suction hole 91 is provided on the horizontal baffle 9. The reflux inlet 12a on the mixing tank 12 is located between the horizontal baffle 9 and the bottom wall of the mixing tank 12. Thus, when the stirring assembly 13 generates suction, the refluxed aqueous phase in the reflux pipe 8 can be sucked into the horizontal baffle 9 through the reflux suction hole 91 and remixed, which helps to achieve liquid level balance between stages. In practical applications, there can be one or more aqueous phase outlets 22b, such as... Figure 1 Two are shown, which promptly remove the remaining aqueous phase from the clarification chamber, thereby improving the extraction efficiency.

[0049] In some exemplary implementations, such as Figure 3 and Figure 4 As shown, the phase separation zone 22 is provided with a second vertical baffle 221 at one end away from the liquid distribution zone 21. The second vertical baffle 221 and the bottom wall of the phase separation zone 22 have a water passage 225. The second vertical baffle 221 is used to form a water outlet channel communicating with the water passage at the end of the phase separation zone 22. The water phase outlet 22b and the water phase return outlet 22c are located on the water outlet channel, so that the separated water phase can enter the water outlet channel through the water passage 225 and then flow out from the water phase outlet 22b and the water phase return outlet 22c located in the water outlet channel.

[0050] In some exemplary embodiments, a perforated plate 222 is horizontally arranged in the water outlet channel. The first outlet pipe 223 and the second outlet pipe 224 pass through the perforated plate 222 and are connected to the water phase outlet 22b and the water phase return outlet 22c respectively via threads 226. It should be noted that the perforated plate 222 is not a solid plate, thus allowing liquid to pass through. Specifically, as shown... Figure 3 As shown, the first outlet pipe 223 passes through the perforated plate 222 and is threadedly connected to the water phase outlet 22b, so that the height of the first outlet pipe 223 can be adjusted by adjusting the depth of its threaded connection; as shown Figure 4As shown, the second outlet pipe 224 passes through the perforated plate 222 and is connected to the water phase return outlet 22c by a thread. The height of the second outlet pipe 223 can be adjusted by adjusting the depth of its thread connection, and the proportion of the return water phase can be adjusted by adjusting the height of the first outlet pipe 223 and the height of the second outlet pipe 223.

[0051] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0052] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
