Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of separation, and in particular relates to a stratification device. Background Art
[0002] In the chemical industry, we often encounter the situation of liquid-liquid separation of two immiscible liquids with different specific gravities. The principle of the automatic overflow stratification tank for light and heavy phases is based on the density difference between the light and heavy phases. The height of the stratification interface satisfies ρheavy*h3=ρheavy*h2+ρlight*h1. When the density of the light and heavy phases changes during actual operation, it will also cause changes in h1 and h2. Therefore, the stratification interface is affected by the density of the light and heavy phases and the height of the overflow port of the light and heavy phases. Due to the deviation between the density at the time of design and the density during actual operation, the density of the light and heavy phases will change at different times, resulting in the actual stratification interface not being in the original design position. In severe cases, the light and heavy phases cannot be separated.
[0003] The traditional stratification trough has poor stratification effect, has a great impact on the stable operation of the system, and wastes a lot of manpower and material resources. Therefore, the development of a new stratification device is an urgent problem to be solved. Utility Model Content
[0004] In order to solve the problems existing in the existing stratification tank, the utility model proposes a new stratification device, including a tank body and a stratification controller, wherein the stratification controller is located outside the tank body, the tank body has a material inlet and a material outlet, and a partition is arranged in the tank body to divide the tank body into a buffer zone and a stratification zone; the material outlet includes: a light phase overflow port, a light phase outlet, a tank body bottom outlet, and a tank body top outlet;
[0005] The layered controller is respectively connected to the bottom outlet of the tank body and the top outlet of the tank body;
[0006] A lifting platform is arranged at the bottom of the layered controller.
[0007] Beneficial effect: The stratification device adopts an external stratification controller, which realizes light and heavy phase stratification by raising or lowering the lifting platform, solving the problem that the light and heavy phase stratification cannot be adjusted.
[0008] In an optional embodiment, the partition includes a first partition and a second partition, and the trough body is divided into a first buffer zone, a second buffer zone and a stratified zone in a direction from the first partition to the second partition.
[0009] Beneficial effect: The partition can prevent the mixed liquid from impacting the liquid surface when entering the stratification tank, reduce the vortex phenomenon of the mixed liquid in the stratification tank, and make the light and heavy phase liquids in the stratification zone overflow and stratify better.
[0010] In an optional embodiment, the stratification area of the trough body is provided with a first viewing mirror, a second viewing mirror, and a third viewing mirror, wherein the interface condition of the stratification interface can be observed in the first viewing mirror, the condition of the liquid level line can be observed in the second viewing mirror, and the condition of the heavy phase zone can be observed in the third viewing mirror.
[0011] Beneficial effect: The first sight glass, the second sight glass and the third sight glass are respectively arranged on the tank body of the stratification zone, so that the conditions at the stratification interface, the liquid level line and the heavy phase zone can be observed respectively, replacing the function of the glass plate level meter, thus avoiding the problem of disordered display of the level meter when an abnormality occurs in the stratification device, and making it possible to conveniently and accurately judge whether the stratification tank is operating normally.
[0012] In an optional implementation manner, the first partition plate and the second partition plate are both fixed to one side wall of the trough body, and a gap is provided between the first partition plate and the other side wall of the trough body.
[0013] Beneficial effects: The gap between the partition and the side wall of the tank body can buffer the flow of the mixed liquid and prevent the static stratification of the mixed liquid from being stirred. At the same time, it ensures that the liquid levels in the buffer zone and the stratification zone are flush, and replenishes the stratification zone.
[0014] In an optional implementation manner, the layered controller is provided with an external tube and an internal tube, the internal tube is sleeved inside the external tube, the top of the internal tube is a heavy phase overflow port, and the heavy phase overflow port is located inside the external tube.
[0015] Beneficial effect: The internal tube sleeve is arranged inside the external tube, which can ensure that the heavy phase overflowing from the heavy phase overflow port of the internal tube is discharged through the heavy phase outlet of the external tube, thereby realizing the unified discharge of the heavy phase.
[0016] In an optional implementation manner, the lifting platform adjusts the liquid level height of the heavy phase overflow port of the built-in tube.
[0017] Beneficial effect: When the density of the light and heavy phases changes, the height of the heavy phase overflow port can be adjusted to return the stratified interface to a normal state, thus avoiding the risk of reduced production capacity or even shutdown of the device due to the inability to separate phases.
[0018] In an optional implementation manner, the bottom outlet of the tank body is connected to the bottom inlet of the built-in tube.
[0019] Beneficial effect: After the light and heavy phases are separated in the tank, the heavy phase is at the lower end, and its connection with the bottom inlet of the built-in pipe is conducive to adjusting the liquid level height of the heavy phase overflow port.
[0020] In an optional implementation manner, a gas phase balance port and a heavy phase outlet are provided on the external tube of the layered controller, and the gas phase balance port is located at a higher height than the heavy phase outlet;

[0023] In an optional implementation manner, the top outlet of the tank body is connected to the gas phase equilibrium port.
[0024] Beneficial effect: The two are connected to the stratification tank and the external stratification controller to balance the pressure between the two.

[0039] This embodiment provides a layered device, and its structural diagram is as follows Figure 1As shown, the tank body 1 includes a tank body 1 and an external stratification controller 7. The stratification controller 7 is located outside the tank body 1. The tank body 1 has a material inlet 11 and a material outlet. The material outlets include: a light phase overflow port 12, a light phase outlet 13, a tank body bottom outlet 14, and a tank body top outlet 15. The tank body 1 is provided with a first baffle 5 and a second baffle 6, which divide the tank body 1 into a first buffer zone, a second buffer zone and a stratification zone. The baffle partition can prevent the mixed liquid from impacting the liquid surface when entering the stratification tank, reduce the eddy current phenomenon of the mixed liquid in the stratification tank, and make the light and heavy phase liquids in the stratification zone overflow and separate better. Layer; one side of the partition is fixed to one side of the tank body 1, and a gap is formed between the other side of the tank body 1, and the gap spacing is 3-20mm. If the spacing is too small, the liquid passes too slowly. If the gap is too large, the liquid passing through will disturb the stratified liquid and remix it, resulting in incomplete stratification; the stratification area of the tank body 1 is provided with a first sight glass 2, a second sight glass 3, and a third sight glass 4. The interface of the stratification interface can be observed in the first sight glass 2, the liquid level line can be observed in the second sight glass 3, and the heavy phase area can be observed in the third sight glass 4. The sight glass is a circular sight glass. It can replace the function of the glass plate level meter, avoid the problem of the level meter display disorder when the stratification device is abnormal, and can conveniently and accurately judge whether the stratification tank is operating normally; the height of the light phase overflow port 12 is higher than the lower boundary of the second mirror 3 and lower than the upper boundary of the second mirror 3; the stratification controller 7 is respectively connected with the bottom outlet 14 of the tank body and the top outlet 15 of the tank body; the bottom of the stratification controller 7 is provided with a lifting platform 8, which can be used to adjust the liquid level height of the heavy phase overflow port 721 of the internal pipe 72; the external stratification controller 7 is provided with an external pipe 71 and an internal pipe 72 The internal tube 72 is sleeved on the inner side of the external tube 71, the top of the internal tube 72 is a heavy phase overflow port 721, and the heavy phase overflow port 721 is located inside the external tube 71; the bottom inlet 722 of the internal tube is connected with the bottom outlet 14 of the tank body through a hose, the top of the external tube 71 is provided with a layered controller viewing mirror 75, and the bottom of the external tube 71 is provided with a heavy phase outlet 74; the upper part of the external tube 71 is provided with a gas phase balance port 73, the position height of the gas phase balance port 73 is higher than the position height of the heavy phase outlet 74, and the gas phase balance port 73 is connected with the top outlet 15 of the tank body through a hose.
[0040] Working principle:
[0041] The mixed liquid enters the first buffer zone of the stratification device tank body 1, buffers the mixed liquid flow through the first partition plate 5, enters the second buffer zone to buffer the mixed liquid flow, and flows into the stratification zone through the gap between the first partition plate 5 and the second partition plate 6 and the side wall of the tank body 1. The mixed liquid is allowed to stand and stratify in the stratification zone. The light phase overflows from the light phase overflow port 12 and flows out of the stratification tank from the light phase outlet 13; the heavy phase enters the built-in pipe 72 of the external stratification controller from the tank body bottom outlet 14, overflows from the heavy phase overflow port 721 to the external pipe 71, and flows out from the heavy phase outlet 74. The top outlet 15 of the stratification device tank body and the gas phase balance port 73 of the external pipe of the stratification controller are connected through a hose to balance the pressure between the two.
[0042] According to ρheavy*h3=ρheavy*h2+ρlight*h1, we can know that h3=h2+ρlight / ρheavy*h1. When ρlight<ρheavy, h1 and h2 remain unchanged (the volume ratio of the light and heavy phases remains unchanged), if ρlight increases due to the addition of a small amount of impurities during actual operation, the value of h3 increases according to the formula, and the height of the heavy phase overflow port can be increased by adjusting the lifting platform; if ρheavy increases due to the addition of a small amount of impurities during actual operation, the value of h3 decreases according to the formula, and the height of the heavy phase overflow port can be lowered by adjusting the lifting platform.
[0043] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
