Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a separation tank. Background Technology

[0002] In the chemical industry, petroleum refining, and environmental protection, the efficient separation of immiscible liquid mixtures is a crucial unit operation. Currently, liquid separation technologies are quite mature. Simple gravity settling tanks utilize density differences between liquids to achieve natural stratification, offering a simple structure and low cost. For emulsions or systems with minimal density differences, high-intensity equipment such as centrifuges can be used, resulting in fast separation speeds and high efficiency. In certain specific processes, the difference in boiling points between components is also utilized for separation through evaporation or distillation, yielding high-purity products. However, despite significant advancements in existing technologies, some aspects still require optimization in the pursuit of energy conservation, high efficiency, and stable production. Specifically, while traditional gravity settling tanks have low energy consumption, their simple internal flow field makes them highly susceptible to fluctuations in feed flow rate, causing the already stratified liquids to be re-turbid, making it difficult to guarantee separation efficiency and stability, and posing significant challenges for automated control. Separation methods relying on phase change, such as evaporation, while precise, consume large amounts of heat energy, leading to high production costs, which is inconsistent with the development trend of green chemistry.

[0003] Therefore, this application provides a separation tank to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a separation tank that aims to solve the problems of low separation efficiency, high energy consumption, and unstable operation of existing separation equipment.

[0005] To achieve the above objectives, this application provides the following technical solution: a separation tank, comprising a tank body, wherein the side wall of the tank body is provided with a mixed liquid inlet, a light phase outlet, and a heavy phase outlet; the mixed liquid inlet is located at the lower part of the tank body, the light phase outlet is located above the mixed liquid inlet, and the heavy phase outlet is located below the light phase outlet; The tank body is equipped with a flow stabilizer plate and a coalescing plate inside. Both the flow stabilizer plate and the coalescing plate are porous plates. The flow stabilizer plate is located inside the feed inlet of the mixed liquid, and the coalescing plate is located above the flow stabilizer plate. The tank is also equipped with an anti-vortex plate, which is located inside the light phase outlet. Through the cooperation of the above components, the efficiency and stability of liquid-liquid separation can be significantly improved.

[0006] Preferably, the light phase outlet includes a first light phase outlet and a second light phase outlet arranged vertically; the height of the top of the coalescing plate is between the first light phase outlet and the second light phase outlet, which improves the product purity.

[0007] Preferably, the side wall of the tank is provided with an upper liquid level gauge interface, and the top of the tank is provided with a top instrument interface for installing liquid level measuring instruments, providing a reliable structural foundation for realizing automated monitoring and control of the separation process.

[0008] Preferably, the side wall of the tank is also provided with a first field sight glass and a second field sight glass. The first field sight glass and the second field sight glass are used to observe the liquid level at different heights, which facilitates the operator to make intuitive on-site confirmation and enhances the safety and convenience of operation.

[0009] Preferably, the tank body is provided with a top manhole and a top gas phase port at the top, and a cleaning port at the bottom, which facilitates the daily inspection, maintenance and cleaning of the equipment.

[0010] In summary, the technical effects and advantages of this utility model are as follows: In this invention, by setting vertical flow stabilizing plates and coalescing plates inside the tank, the incoming mixed liquid flow is first stabilized and evenly distributed, and then the coalescing plates are used to promote the merging and growth of fine light phase droplets, which significantly enhances the stability of the separation process and improves the separation efficiency.

[0011] In this invention, by setting the light phase outlet in the middle of the tank and using an anti-vortex plate on its inner side, the lower heavy phase liquid is effectively prevented from being drawn in by vortices when the light phase liquid is discharged, thus ensuring the purity of the product.

[0012] This invention operates at normal temperature and pressure based on the principle of gravity settling, eliminating the need for external energy for heating. This fundamentally avoids the enormous energy consumption caused by the phase change process, significantly reducing the operating cost of the equipment and resulting in good economic benefits.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] refer to Figure 1-4 The separation tank shown addresses the problems of low efficiency, high energy consumption, and unstable operation in existing liquid-liquid separation technologies. By combining a unique flow stabilizing plate 30, a coalescing plate 40, a light phase discharge port 50 in the middle, and an anti-vortex plate 51 inside, it achieves efficient, stable, and easily automated separation of immiscible liquid mixtures, resulting in energy saving, reduced consumption, and improved product purity.

[0018] As one embodiment of this invention, it includes a tank 10, which is cylindrical in shape and sealed at the top and bottom with end caps. To enable material input and output, multiple sets of interfaces are provided on the side wall of the tank 10. The mixed liquid inlet 20 is located at the lower part of the tank 10. The light phase outlet 50 includes two interfaces arranged vertically and is higher than the mixed liquid inlet 20. The heavy phase outlet 60 is located at the lower part of the tank 10 and below the light phase outlet 50. This layered interface design provides a structural basis for subsequent continuous and stable separation operations.

[0019] As one embodiment of this invention, the tank 10 is equipped with two porous plate structures: a flow stabilizing plate 30 and a coalescing plate 40. The flow stabilizing plate 30 is vertically arranged inside the tank 10, directly opposite the inner side of the mixed liquid inlet 20. Its main function is to buffer and dissipate energy from the high-speed incoming mixed liquid flow, and to distribute the liquid flow evenly across the entire cross-section of the tank through its multiple holes, creating a stable fluid environment for subsequent gravity sedimentation separation. The coalescing plate 40 is also a porous plate, vertically arranged inside the tank 10, and located above the flow stabilizing plate 30. Its function is to allow dispersed, fine light phase droplets to collide and merge with each other as they float upwards, coalescing into larger droplets, thereby accelerating the floating and stratification speed and significantly improving separation efficiency. The vertical height of the coalescing plate 40 is located between the upper and lower light phase outlets 50, forming a cooperative structural relationship.

[0020] As one embodiment of this example, an anti-vortex plate 51 is also provided inside the tank 10 on the inner side of the light phase outlet 50. When the tank 10 discharges light phase liquid, the anti-vortex plate 51 prevents the formation of vortices at the outlet due to the high flow rate, and avoids the vortex from entraining and carrying out the lower heavy phase liquid, thereby effectively ensuring the purity of the discharged light phase liquid.

[0021] As one implementation method in this embodiment, in order to achieve precise monitoring of the separation process, the tank 10 is also equipped with instruments and observation interfaces. The side wall of the tank 10 is equipped with an upper liquid level gauge interface 80 for installing a remote liquid level gauge sensor; the top end cap is equipped with a top instrument interface 72 for installing a liquid level measuring instrument, for connecting the sensor and the display instrument. The side wall of the tank 10 is also equipped with two first field sight glasses 81 and second field sight glasses 82 at different heights, so that the on-site operators can directly observe the interface position and separation status of the light and heavy phases in the tank.

[0022] As one embodiment of this invention, in order to facilitate the daily maintenance and repair of the equipment, the top end cap of the tank 10 is also provided with a top manhole 70 and a top gas phase port 71, and a cleaning port 90 is provided at the bottom. The top manhole 70 is used for personnel to enter the tank for maintenance and cleaning, the top gas phase port 71 is used to discharge or collect the gas in the tank, and the bottom cleaning port 90 is used to drain the residual liquid and cleaning wastewater in the tank.

[0023] The working principle of this practical system is as follows: The mixed liquid to be separated enters from the mixed liquid inlet 20 at the bottom of the tank 10. It is first blocked and evenly distributed by the flow stabilizer 30, and the flow velocity is reduced before it flows smoothly upward. During the slow ascent, due to the density difference, the heavier liquid components sink, while the lighter liquid components float in the form of fine droplets. The floating light phase droplets are accelerated to stratification by the coalescence plate 40 above, and finally two clear layers are formed inside the tank 10. The separated light phase liquid is discharged from the light phase outlet 50 located in the middle, and the anti-vortex plate 51 ensures the smoothness of the discharge process. The separated heavy phase liquid is discharged from the heavy phase outlet 60 located at the bottom. The entire process can be monitored in real time by a level gauge and a field sight glass to achieve continuous, efficient and stable automated separation.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
