Description

Technical Field

[0001] This utility model belongs to the field of mixed solution stratification, and specifically relates to a mixed solution stratification device. Background Technology

[0002] In the field of chemical separation, the stratification treatment of dichloromethane and water mixtures in continuous production scenarios faces challenges due to the need for dynamic and continuous processing of the mixture, rather than batch-based static stratification. Liquid flows directly from the inlet to the outlet of the storage tank, resulting in rapid flow (insufficient residence time). Natural stratification (relying on gravity settling) caused by density differences is not yet complete. The short residence time of the mixed solution leads to insufficient stratification, incomplete dichloromethane recovery, and significant difficulties and costs in wastewater treatment. Furthermore, the poor flow of the mixed solution within the storage tank restricts the processing flow rate, easily causing localized pressure imbalances and interface disturbances, resulting in poor and unstable separation performance. Utility Model Content

Detailed Implementation

[0032] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0033] See Figures 1 to 11 A mixed solution stratification device, comprising a storage tank 1 and at least two partitions 2 vertically arranged within the storage tank 1, wherein:

[0034] The storage tank 1 is cuboid in shape and has opposite upper and lower sides, opposite front and rear sides, and opposite left and right sides. The upper side of the storage tank 1 is provided with an air outlet 104 and an observation port. The observation port is provided with a cover plate 107. Removing the cover plate makes it easy to observe the liquid state in the storage tank 1. One of the front and rear sides of the storage tank 1 is provided with an inlet 101 and the other is provided with a first outlet 102. The bottom side of the storage tank 1 is provided with a second outlet 103. The inlet 101 is for the mixed solution to enter. The mixed solution is a mixture of dichloromethane and water. Dichloromethane and water have a density difference (dichloromethane is denser than water), which can achieve stratification. Dichloromethane sinks to the bottom layer and water floats to the top layer. The first outlet 102 is for the water after stratification to flow out, and the second outlet 103 is for the dichloromethane after stratification to flow out. The first outlet 102 is used to connect with the aeration tank. The upper water overflows from the first outlet 102 into the aeration tank, and after further aeration to remove trace amounts of dichloromethane, it enters the wastewater system. The second outlet 103 is used to connect with the dichloromethane storage tank. The first outlet 102 is connected to the dichloromethane storage tank through a pipeline. A transfer pump is installed on the pipeline, and the dichloromethane in the lower layer is sent to the dichloromethane storage tank for recovery through the transfer pump.

[0035] At least two partitions 2 are distributed along the left and right directions, and at least two partitions 2 divide the liquid storage tank 1 into multiple chambers. The multiple chambers are distributed sequentially and connected along the left and right directions. The multiple chambers include a first chamber, an intermediate chamber (one or more), and a last chamber.

[0036] The partition 2 is a square plate with opposite upper and lower sides, opposite front and rear sides, and opposite left and right sides. The front and rear sides of the partition 2 extend vertically. The lower side of the partition 2 is connected to the bottom of the storage tank 1. The upper side of the partition 2 maintains a gap with the top of the storage tank 1 to form a first flow channel. One of the front and rear sides of the partition 2 is fixedly connected to the side wall corresponding to the storage tank 1, and the other side maintains a gap with the side wall corresponding to the storage tank 1 to form a second flow channel. The second flow channels formed by two adjacent partitions 2 and the storage tank 1 are staggered, that is, the second flow channels formed by two adjacent partitions 2 and the storage tank 1 are not located on the same side of the storage tank 1. This can extend the path of the mixed solution in the storage tank 1, prolong the residence time, and facilitate stratification.

[0037] The first partition 2 is adjacent to the liquid inlet 101, and the last partition 2 is adjacent to the first liquid outlet 102. The liquid inlet 101 is located on the side of the first partition 2 away from the last partition 2, and the first liquid outlet 102 is located on the side of the last partition 2 away from the first partition 2. The second flow channel formed by the first partition 2 and the liquid storage tank 1 has one inlet 101 located at the front of the liquid storage tank 1 and the other at the rear of the liquid storage tank 1, extending the path of the mixed solution in the liquid storage tank 1 and prolonging the residence time. The second flow channel formed by the last partition 2 and the liquid storage tank 1 has one inlet 102 located at the front of the liquid storage tank 1 and the other at the rear of the liquid storage tank 1. The second liquid outlet 103 is located in the last chamber where the last partition 2 is located. A feeding area is formed between the first partition 2 and the left side wall of the liquid storage tank 1, and a discharging area is formed between the last partition 2 and the right side wall of the liquid storage tank 1. By separating the feeding area and the discharging area, the impact of disturbance on stratification is reduced.

[0038] In one embodiment, see Figure 3 If the first outlet 102 is located on the front side of the storage tank 1, and the inlet 101 is located on the rear side of the storage tank 1, with the inlet 101 near the left end of the rear side of the storage tank 1 and the first outlet 102 near the right end of the front side of the storage tank 1, that is, the distance between the inlet 101 and the first outlet 102 is large, the residence time of the mixed solution is long. Two partitions 2 can be provided, one partition 2 near the inlet 101 and the other partition 2 near the first outlet 102, that is, the inlet 101 and the first outlet 102 are located on the side of the two partitions 2 furthest from each other; the two partitions 2 divide the storage tank 1 into three chambers, namely chambers A, B, and C. The inlet 101 is opened on chamber A, the first outlet 102 is opened on chamber C, and the second outlet 103 is opened at the bottom of chamber C. A gap is maintained between the front side of the partition 2 on the left and the front side of the storage tank 1 to form a second flow channel (e.g., Figure 3 (as indicated by a in the middle), a gap is maintained between the rear side of the partition 2 on the right side and the rear side of the liquid storage tank 1 to form a second flow channel (as shown in the middle a). Figure 3 (as indicated by b in the middle).

[0039] In one specific embodiment, the liquid storage tank 1 has a length of 1900mm, a width of 900mm, a height of 1250mm, a plate thickness of 3mm, an inner length of 1894mm, and an inner width of 894mm. The partition 2 has a length of 889mm, a height of 1206mm, and a thickness of 3mm. One of the front and rear sides of the partition 2 is welded and fixed to the inner wall of the liquid storage tank 1, while the other side maintains a 5mm gap with the inner wall of the liquid storage tank 1.

[0040] The process of flow and stratification of the mixed solution is as follows: Taking a mixed solution of dichloromethane and water (approximately 4 tons of water and approximately 2 tons of dichloromethane) as an example, the mixed solution is fed into the inlet 101, first entering the lower left corner of chamber A of storage tank 1, and then flowing to the gap between the first baffle 2 and the inner wall of storage tank 1 (e.g., Figure 3 At point a (indicated by a), the flow path is approximately 889 mm, then it flows through the gap at point a into chamber B. During the flow and settling process, stratification occurs due to the density difference between dichloromethane and water (dichloromethane is denser than water), with dichloromethane settling in the lower layer and water floating in the upper layer. Next, it flows from chamber B into the gap between the second partition 2 and the inner wall of the storage tank 1 (as shown by a line in the image). Figure 3 At point (b), the flow path is approximately 889 mm. After passing through the gap at point b, the water flows into chamber C. The upper layer of water is then discharged from the first outlet 102 on chamber C, with a flow path of approximately 889 mm. Dichloromethane at the bottom is discharged from the second outlet 103.

[0041] The partition 2 is designed with a vertical side gap (not for top or bottom overflow) and a small gap width, allowing the mixed solution to pass smoothly in a laminar flow state (low Reynolds number, no turbulent disturbance). As the liquid flows around, the upper water and lower dichloromethane have already undergone preliminary stratification. The flow direction at the gap is parallel to the stratification interface (rather than perpendicularly penetrating the interface). When flowing through the gap, the two preliminarily stratified liquids flow along their respective phase layers, thus not disrupting the existing stratification, but rather "carrying the stratified liquids in an orderly manner." At least two partitions 2 are used to disperse the impact force of the liquid flow, making the mixed solution more evenly distributed within the storage tank 1. The presence of each gap allows for adjustment of the liquid flow velocity and direction, avoiding localized turbulence or "short-circuiting" (i.e., liquid flowing out before sufficient stratification), maintaining the stability of each stratification interface, and reducing the remixing of the upper water and lower dichloromethane.

[0042] The layout of the mixed solution's feed and discharge points is such that the feed inlet is located on one side of the storage tank 1 because the feeding process disturbs the liquid, directly affecting the stratification effect. Without baffles 2, the flow path of the mixed solution within the tank is short, resulting in insufficient residence time and making it difficult to achieve sufficient stratification. With baffles 2, the disturbance on the feed side is confined to one side, and the mixed solution, having passed through the gaps between at least two baffles 2 and the sidewall of the storage tank, reaches the discharge side already in a stratified state. The second discharge port 103 is located at the bottom of the storage tank 1, collecting the lower layer of dichloromethane. The first discharge port 102 is positioned higher than the second discharge port 103 to avoid disturbing the already stratified liquid and ensure a smooth separation process. This design extends the residence time of the mixed solution within the tank, providing sufficient stratification time and improving the dichloromethane recovery rate and wastewater treatment quality. Furthermore, multiple baffles 2 are installed, with the second flow channel formed by two adjacent baffles 2 and the storage tank 1 staggered. The mixed solution sequentially passes through the gaps between each baffle 2 and the inner wall of the storage tank 1, forming a serpentine / zigzag flow path. This ensures that the mixed solution has sufficient residence time in the storage tank 1, while also guaranteeing smooth liquid flow and stability of the stratification interface. This optimizes the stratification process of the mixed solution and improves separation efficiency and quality. Compared to designs without baffles 2, or with only a single baffle 2, this effectively solves the problems of insufficient stratification and low separation efficiency.

[0043] Preferably, an extension plate 3 is provided on the upper side of the partition 2, the extension plate 3 extends towards the first liquid outlet 102, and the extension plate 3 extends along the flow direction of the mixed solution (e.g., Figure 6 , 8 (The middle extends to the right), and the extension plate 3 plays a role in strengthening and guiding. On the one hand, it increases the strength of the partition 2, and on the other hand, it guides the liquid to flow to the next partition 2.

[0044] In some embodiments, the extension plate 3 is perpendicular to the partition plate 2.

[0045] In some embodiments, the gap between the front and rear sidewalls of the partition 2 and the other sidewall corresponding to the liquid storage tank 1 is in the range of 2-10 mm, preferably 5 mm.

[0046] In some embodiments, the device further includes an inlet pipe 13 located in the liquid storage tank 1 and connected to the inlet port 101. The inlet pipe 13 includes a first pipe body 131 and a second pipe body 132. One end of the first pipe body 131 is connected to the inlet port 101, and the other end of the first pipe body 131 is connected to one end of the second pipe body 132. The other end of the first pipe body 131 extends toward the side of the liquid storage tank 1 opposite to the side where the inlet port 101 is located, and the other end of the second pipe body 132 extends toward the bottom of the liquid storage tank 1.

[0047] In this example, to ensure stable stratification, the device also includes a liquid guiding component 4, which is installed in the liquid storage tank 1. The liquid guiding component 4 has multiple flow channels and is located above the second liquid outlet 103, so that the lower layer liquid after stratification flows into the second liquid outlet 103 in multiple streams through multiple flow channels, reducing vortices and ensuring stable stratification.

[0048] In some embodiments, the liquid guiding member 4 includes a main body and a plurality of extension portions, the number of extension portions being two or more, the extension portions being connected to the outer periphery of the main body and distributed along the circumference of the main body, and a gap being maintained between two adjacent extension portions to form a flow channel; one end of the extension portion away from the main body extends a distance from the second liquid outlet 103.

[0049] See Figure 10-11 The liquid guiding component 4 is composed of two long strip plates connected in a cross shape. One of the long strip plates has a downward recessed groove, and the other long strip plate is inserted into the groove. The liquid guiding component 4 has four flow channels. The liquid guiding component 4 has a simple structure and is easy to process and operate.

[0050] In some embodiments, the device further includes a glass tube level gauge 5, a first connecting pipe 6, a second connecting pipe 7, and a support member 8. The glass tube level gauge 5 is vertically arranged and can visually display the layered interface for easy observation. The upper and lower ends of the glass tube level gauge 5 are connected to the first connecting pipe 6 and the second connecting pipe 7, respectively. Both the first connecting pipe 6 and the second connecting pipe 7 are connected to the storage tank 1 and are arranged parallel to each other, perpendicular to the storage tank 1. The support member 8 connects the first connecting pipe 6 and the second connecting pipe 7, extends vertically, and is parallel to the glass tube level gauge 5. The support member 8 better supports the first connecting pipe 6 and the second connecting pipe 7, thereby better protecting the glass tube level gauge 5. (See also...) Figure 1 The support member 8 is preferably a long strip plate.

[0051] In some embodiments, the device further includes a reinforcing member 11, which is arranged around the outer periphery of the liquid storage tank 1 to improve the strength of the liquid storage tank 1. The reinforcing member 11 is located in the middle part of the outer side of the liquid storage tank 1. The reinforcing member 11 is in the shape of a horizontal plate and includes four reinforcing plates, which are respectively arranged on the front, left, rear and right sides of the liquid storage tank 1.

[0052] In some embodiments, the device further includes a first reinforcing connecting plate 9 and a second reinforcing connecting plate 10. The first reinforcing connecting plate 9 is connected to the outer wall of the first connecting pipe 6 and the liquid storage tank 1. Multiple first reinforcing connecting plates 9 can be provided, such as three. The three first reinforcing connecting plates 9 are respectively located on the upper side, left side, and right side of the first connecting pipe 6. The first reinforcing connecting plates 9 on the left and right sides of the first connecting pipe 6 are located below the reinforcing member 11. The second reinforcing connecting plate 10 is connected to the outer wall of the second connecting pipe 7 and the liquid storage tank 1. Multiple second reinforcing connecting plates 10 can be provided, such as three. The three second reinforcing connecting plates 10 are respectively located on the lower side and left and right sides of the second connecting pipe 7. The first reinforcing connecting plate 9 on the upper side of the first connecting pipe 6 and the second reinforcing connecting plate 10 on the lower side of the second connecting pipe 7 are located on the same vertical line as the support member 8. The provision of the first reinforcing connecting plate 9 and the second reinforcing connecting plate 10 better supports and fixes the first connecting pipe 6 and the second connecting pipe 7, thereby ensuring the stable installation of the glass tube level gauge 5.

[0053] The device also includes a float level gauge, which is installed on the upper side of the storage tank 1. The float level gauge is remotely connected to the transfer pump to control the start and stop of the bottom transfer pump, thereby accurately controlling the liquid level in the storage tank 1.

[0054] In some embodiments, at least one of the front, rear, left, and right sides of the liquid storage tank 1 has a recess 105, which is recessed into the liquid storage tank 1. The recess 105 serves to provide a buffer for the mixed solution stored in the liquid storage tank 1. See also Figure 1 The concave section 105 has a V-shaped cross-section.

[0055] The advantages of the mixed solution stratification device in this example are as follows: By setting multiple baffles 2, the lower side of the baffle 2 is connected to the bottom of the storage tank 1, and the upper side of the baffle 2 is maintained with a gap to form a first flow channel with the top of the storage tank 1. One of the front and rear sides of the baffle 2 is fixedly connected to the side wall corresponding to the storage tank 1, and the other side is maintained with a gap to form a second flow channel with the side wall corresponding to the storage tank 1. The second flow channels formed by two adjacent baffles 2 and the storage tank 1 are staggered, forcing the mixed solution to flow along a specific path, forcibly extending the flow path, increasing the residence time of the mixed solution in the storage tank 1, ensuring more thorough stratification, and simultaneously making the liquid... Uniform flow of the liquid avoids disturbance to the stratification interface caused by top / bottom overflow, maintains the stability of the stratification interface, improves separation accuracy, and enhances separation efficiency and quality. It enables continuous operation of "feeding, stratification, and discharge simultaneously," maintaining the continuity of the production process. The optimized flow path and stratification environment of the mixed solution not only avoid stratification disorder caused by top and bottom overflow, but also reduce the impact of disturbance on stratification by separating the feed area and the discharge area. Sufficient residence time and a stable stratification environment enable more thorough separation of dichloromethane and water, improve the dichloromethane recovery rate, reduce the residual amount of dichloromethane in wastewater, and alleviate the pressure on subsequent treatment.

[0056] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
