Description
Technical Field
[0001] The utility model relates to the technical field of phase separators for ethyl acetate synthesis, and particularly relates to a phase separator for ethyl acetate synthesis that reduces backmixing. Background Art
[0002] Ethyl acetate is a colorless transparent liquid with a fruity smell, slightly soluble in water, miscible with most organic solvents such as alcohols and benzene, and belongs to the low-toxicity category. It is used as an industrial solvent in varnishes, coatings, artificial leather, printing inks, etc. The processing of ethyl acetate usually requires the use of a phase separator.
[0003] In a common phase separator for ethyl acetate synthesis, when the mixture enters the phase separator, if the flow rate is too fast or there is no appropriate deceleration mechanism, turbulence may be formed, resulting in backmixing. And if the residence time of the mixture in the phase separator is too short, the two phases may not be fully stratified, leading to frequent backmixing phenomena. This not only reduces the concentration of the ester phase but also affects the phase separation efficiency.
[0004] Therefore, for the above-mentioned phase separator for ethyl acetate synthesis with frequent backmixing phenomena, which not only reduces the concentration of the ester phase but also affects the phase separation efficiency, a phase separator for ethyl acetate synthesis that reduces backmixing can be designed. By starting the refrigerator, the refrigerator transports air into the cooling cavity through the air exchange pipe, making the temperature of the cooling cylinder relatively low. Reducing the temperature can reduce the volatilization of ethyl acetate, not only reducing backmixing, effectively increasing the concentration of the ester phase, but also improving the phase separation efficiency. This structure further reduces the backmixing phenomenon and improves the phase separation efficiency through multi-stage deceleration to increase the residence time, and increases the concentration of the ester phase by reducing the volatilization of ethyl acetate through lowering the temperature to solve the above problems. Summary of the Utility Model
[0005] In order to overcome the problems of a common phase separator for ethyl acetate synthesis, such as frequent backmixing phenomena, which not only reduces the concentration of the ester phase but also affects the phase separation efficiency.
[0006] The technical solution of the present utility model is as follows: A phase separator for ethyl acetate synthesis that reduces backmixing, comprising a phase separator main body; further comprising a baffle cover, a first deceleration plate, a second deceleration plate, a spiral mixing mechanism, a cooling cylinder, a cooling cavity, a refrigerator, and an air exchange pipe. An inlet is provided on the left end face of the phase separator main body. At the position corresponding to the inlet on the inner left end face of the phase separator main body, a baffle cover is fixedly arranged. A plurality of openings are provided on the outer surface of the baffle cover. On the right side of the baffle cover inside the phase separator main body, a first deceleration plate is fixedly and sealingly arranged. On the side surface of the first deceleration plate close to the baffle cover, a plurality of first feed holes are annularly provided. At the center of the side surface of the first deceleration plate far from the baffle cover, one end of a fixed column is fixedly arranged. On the surface of the end of the fixed column far from the first deceleration plate, a second deceleration plate is fixedly arranged. The outer side of the second deceleration plate is sealingly connected to the inside of the phase separator main body. A spiral mixing mechanism is fixedly arranged on the outer surface of the fixed column. A cooling cylinder is fixedly connected between the first deceleration plate and the second deceleration plate. A cooling cavity is formed between the cooling cylinder and the phase separator main body. On the side surface of the second deceleration plate close to the cooling cylinder, a plurality of second feed holes are annularly provided. A refrigerator is fixedly arranged on the upper end face of the phase separator main body. One end of an air exchange pipe is fixedly connected to the left end face of the refrigerator. The end of the air exchange pipe far from the refrigerator penetrates through the upper end face of the phase separator main body and extends into the inside of the cooling cavity.
[0007] Preferably, the mixed phase of ethyl acetate and water enters the inside of the phase separator main body through the inlet, forms a turbulent flow through the baffle cover for preliminary deceleration, and then enters the inside of the spiral mixing mechanism through the first feed holes on the surface of the first deceleration plate. In the several semi-closed spaces formed by the spiral mixing mechanism, the mixed phase has a longer residence time, thereby providing sufficient time and space for the preliminary phase separation of the mixed phase, and the purpose of mixing and decelerating can be achieved. Then, it enters the next process through the first feed holes on the surface of the second deceleration plate. When the mixed phase is inside the spiral mixing mechanism, by starting the refrigerator, the refrigerator conveys air into the cooling cavity through the air exchange pipe, making the temperature of the cooling cylinder relatively low. Reducing the temperature can reduce the volatilization of ethyl acetate, not only reducing backmixing, effectively increasing the concentration of the ester phase, but also improving the phase separation efficiency. This structure increases the residence time through multi-stage deceleration, further reducing the backmixing phenomenon and improving the phase separation efficiency. By reducing the temperature to reduce the volatilization of ethyl acetate, the concentration of the ester phase is increased.
[0008] Preferably, a phase separation plate is fixedly connected inside the phase separator body. On one side surface of the phase separation plate close to the second deceleration plate, a lower material passing port and an upper material passing port are respectively penetrated. The lower material passing port is located below the upper material passing port. The phase separation plate is fixedly connected inside the phase separator body, behind the second deceleration plate. The setting of the phase separation plate is to further refine the separation process of the mixed phase, reduce the backmixing phenomenon, and improve the phase separation efficiency. The lower material passing port is located below one side of the phase separation plate close to the second deceleration plate, and is used to allow the heavier aqueous phase to pass through. The aqueous phase is located at the lower part of the mixture due to its larger density. The upper material passing port is located above one side of the phase separation plate close to the second deceleration plate, and its position is higher than that of the lower material passing port, and is used to allow the lighter ethyl acetate phase to pass through. The ethyl acetate phase is located at the upper part of the mixture due to its smaller density.
[0009] Preferably, a control panel is installed on the front side surface of the phase separator body, and an observation window is opened on the front side surface of the phase separator body. The operator can start or stop the operation of the refrigerator, adjust the working mode of the refrigerator or set the target temperature through the control panel, and can display real-time information such as temperature and pressure, so as to enable the operator to monitor the state of the phase separation process. The observation window is a transparent window, usually made of chemically resistant materials such as polycarbonate or tempered glass, and is used to observe the situation inside the phase separator, such as the state of the mixture and the phase separation progress.
[0010] Preferably, four support legs are fixedly arranged on the lower end surface of the phase separator body, and a rubber sleeve is respectively fixedly arranged on the lower end surface of the four support legs. The support legs provide stable support for the phase separator body to ensure that it will not move or tilt easily during the operation. The rubber sleeve increases the friction between the support legs and the ground, preventing the phase separator from sliding during the operation. At the same time, the rubber sleeve can adapt to different types of ground and can provide good support on both hard and soft ground.
[0011] Preferably, a drain pipe is installed on the lower end surface of the phase separator body, and a liquid level gauge port is opened on the right side surface of the phase separator body. The drain pipe is used to drain the aqueous phase liquid at the bottom of the phase separator body. The liquid level gauge port is connected to a transparent liquid level gauge, which is used to display the horizontal height of the liquid inside the phase separator body. Through the liquid level gauge, the layering situation of the two phases and their respective heights can be observed, providing the operator with the ability to monitor the change of the liquid level inside the phase separator in real time, which helps to better control the phase separation process.
[0012] Preferably, an ester phase outlet pipe is installed on the upper end surface of the phase separator body, and a thermometer installation port is opened on the upper end surface of the phase separator body. The ester phase outlet pipe is used to discharge the separated ethyl acetate phase from the phase separator body. The ethyl acetate phase is located at the upper end of the phase separator body. Because the density of ethyl acetate is less than that of water, it will float on the aqueous phase. The thermometer installation port cooperates with a thermometer to provide the operator with the ability to monitor the change of the temperature inside the phase separator in real time, which helps to better control the phase separation process.
[0013] Preferably, an electronic liquid level gauge installation port is provided on the upper end surface of the phase separator body. The ester phase outlet pipe is located between the electronic liquid level gauge installation port and the thermometer installation port, and the electronic liquid level gauge installation port is located beside the rear side of the thermometer installation port. The electronic liquid level gauge installation port is used to install an electronic liquid level gauge, which is a sensor that can accurately measure the liquid level height inside the phase separator body. Through the electronic liquid level gauge, the stratification situation of the two phases and their respective liquid level heights can be monitored in real time.
[0014] Advantages of the present utility model:
[0015] 1. The mixed phase of ethyl acetate and water enters the inside of the phase separator body through the feed port, forms a turbulent flow through the baffle cover for preliminary deceleration, and then enters the spiral mixing mechanism through the feed hole 1 on the surface of the first deceleration plate. In the several semi-closed spaces formed by the spiral mixing mechanism, the mixed phase has a longer residence time, thus providing sufficient time and space for the preliminary phase separation of the mixed phase, and the purpose of mixing and decelerating can be achieved. When entering the next process through the feed hole 1 on the surface of the second deceleration plate, when the mixed phase is in the spiral mixing mechanism, by starting the refrigerating machine, the refrigerating machine transports air through the air exchange pipe into the cooling chamber, making the temperature of the cooling cylinder relatively low. Reducing the temperature can reduce the volatilization of ethyl acetate, not only reducing backmixing and effectively increasing the concentration of the ester phase, but also improving the phase separation efficiency. This structure increases the residence time through multi-stage deceleration, further reducing the backmixing phenomenon and improving the phase separation efficiency. By reducing the temperature to reduce the volatilization of ethyl acetate, the concentration of the ester phase is increased. BRIEF DESCRIPTION OF THE DRAWINGS

The lower material passing port 20 is located below one side of the phase separator plate 19 close to the second deceleration plate 17 and is used to allow the heavier water phase to pass through. The water phase is located at the lower part of the mixture due to its larger density.

Four support legs 2 are fixedly arranged on the lower end surface of the phase separator body 1, and a rubber sleeve 3 is respectively fixedly arranged on the lower end surface of the four support legs 2. The support legs 2 provide stable support for the phase separator body 1 to ensure that it will not move or tilt easily during operation. The rubber sleeve 3 increases the friction between the support legs 2 and the ground, prevents the phase separator from sliding during operation, and at the same time the rubber sleeve 3 can adapt to different types of ground and can provide good support whether it is a hard ground or a soft ground.
[0024] Please refer to Figures 1-3, in this embodiment, a drain pipe 22 is installed on the lower end surface of the phase separator body 1, and a liquid level gauge port 23 is provided on the right side surface of the phase separator body 1. The drain pipe 22 is used to discharge the aqueous liquid at the bottom of the phase separator body 1. The liquid level gauge port 23 is connected to a transparent liquid level gauge, which is used to display the horizontal height of the liquid inside the phase separator body 1. Through the liquid level gauge, the layering situation and respective heights of the two phases can be observed, providing the operator with the ability to monitor the change of the liquid level inside the phase separator in real time, which helps to better control the phase separation process. An ester phase outlet pipe 25 is installed on the upper end surface of the phase separator body 1, and a thermometer installation port 26 is provided on the upper end surface of the phase separator body 1. The ester phase outlet pipe 25 is used to discharge the separated ethyl acetate phase from the phase separator body 1. The ethyl acetate phase is located at the upper end of the phase separator body 1. Since the density of ethyl acetate is less than that of water, it will float on the aqueous phase. The thermometer installation port 26 cooperates with a thermometer to provide the operator with the ability to monitor the change of the temperature inside the phase separator in real time, which helps to better control the phase separation process. An electronic liquid level gauge installation port 24 is provided on the upper end surface of the phase separator body 1. The ester phase outlet pipe 25 is located between the electronic liquid level gauge installation port 24 and the thermometer installation port 26. The electronic liquid level gauge installation port 24 is located beside the rear side of the thermometer installation port 26. The electronic liquid level gauge installation port 24 is used to install an electronic liquid level gauge, which is a sensor that can accurately measure the liquid level height inside the phase separator body 1. Through the electronic liquid level gauge, the layering situation and respective liquid level heights of the two phases can be monitored in real time.
[0025] When working, the mixed phase of ethyl acetate and water enters the interior of the phase separator main body 1 through the feed port 6, forms a turbulent flow through the baffle 7 for preliminary deceleration, and then enters the spiral mixing mechanism 14 through the feed hole 10 on the surface of the first deceleration plate 9. In the several semi-closed spaces formed by the spiral mixing mechanism 14, the mixed phase has a longer residence time, thus providing sufficient time and space for the preliminary phase separation of the mixed phase, and the purpose of mixing and deceleration can be achieved. When entering the next process through the feed hole 10 on the surface of the second deceleration plate 17, when the mixed phase is inside the spiral mixing mechanism 14, by starting the refrigerator 15, the refrigerator 15 conveys air into the cooling chamber 12 through the air exchange pipe 16, making the temperature of the cooling cylinder 11 relatively low. Lowering the temperature can reduce the volatilization of ethyl acetate, not only reducing backmixing, effectively increasing the concentration of the ester phase, but also improving the phase separation efficiency. This structure increases the residence time through multi-stage deceleration, further reducing the backmixing phenomenon and improving the phase separation efficiency. By reducing the temperature, the volatilization of ethyl acetate is reduced, and the concentration of the ester phase is increased. The phase separation plate 19 is fixedly connected inside the phase separator main body 1, behind the second deceleration plate 17. The setting of the phase separation plate 19 is to further refine the separation process of the mixed phase, reduce the backmixing phenomenon, and improve the phase separation efficiency. The lower material passing port 20 is located below the side of the phase separation plate 19 close to the second deceleration plate 17, and is used to allow the heavier aqueous phase to pass through. The aqueous phase is located at the lower part of the mixture due to its larger density. The upper material passing port 21 is located above the side of the phase separation plate 19 close to the second deceleration plate 17, and its position is higher than that of the lower material passing port 20, and is used to allow the lighter ethyl acetate phase to pass through. The ethyl acetate phase is located at the upper part of the mixture due to its smaller density. The operator can start or stop the operation of the refrigerator 15 through the control panel 5, adjust the working mode of the refrigerator 15 or set the target temperature, and can display real-time temperature, pressure and other information, so that the operator can monitor the state of the phase separation process. The observation window 4 is a transparent window, usually made of chemically resistant materials such as polycarbonate or toughened glass, and is used to observe the situation inside the phase separator, such as the state of the mixture and the progress of phase separation. The support legs 2 provide stable support for the phase separator main body 1 to ensure that it will not move or tilt easily during operation. The rubber sleeves 3 increase the friction between the support legs 2 and the ground to prevent the phase separator from sliding during operation.Meanwhile, the rubber sleeve 3 can adapt to different types of ground and provide good support on both hard and soft ground. The drain pipe 22 is used to discharge the aqueous liquid at the bottom of the phase separator main body 1. The liquid level gauge port 23 is connected to a transparent liquid level gauge, which is used to display the horizontal height of the liquid inside the phase separator main body 1. Through the liquid level gauge, the layering of the two phases and their respective heights can be observed, providing the operator with the ability to monitor the change of the liquid level inside the phase separator in real time, which helps to better control the phase separation process. The ester phase outlet pipe 25 is used to discharge the separated ethyl acetate phase from the phase separator main body 1. The ethyl acetate phase is located at the upper end of the phase separator main body 1. Since the density of ethyl acetate is less than that of water, it will float on the aqueous phase. The thermometer mounting port 26 is used in conjunction with a thermometer to provide the operator with the ability to monitor the change of the temperature inside the phase separator in real time, which helps to better control the phase separation process. The electronic liquid level gauge mounting port 24 is used to install an electronic liquid level gauge, which is a sensor that can accurately measure the liquid level height inside the phase separator main body 1. Through the electronic liquid level gauge, the layering of the two phases and their respective liquid level heights can be monitored in real time.,
[0026] Through the above steps, the mixed phase of ethyl acetate and water enters the interior of the phase separator main body 1 through the feed port 6, forms a turbulent flow through the baffle 7 for preliminary deceleration, and then enters the spiral mixing mechanism 14 through the feed hole 10 on the surface of the first deceleration plate 9. In the several semi-closed spaces formed by the spiral mixing mechanism 14, the mixed phase has a longer residence time, thus providing sufficient time and space for the preliminary phase separation of the mixed phase and achieving the purpose of mixed deceleration. Then it enters the next process through the feed hole 10 on the surface of the second deceleration plate 17. When the mixed phase is inside the spiral mixing mechanism 14, by starting the refrigerator 15, the refrigerator 15 transports air into the cooling chamber 12 through the air exchange pipe 16, making the temperature of the cooling cylinder 11 relatively low. Lowering the temperature can reduce the volatilization of ethyl acetate, not only reducing backmixing and effectively increasing the concentration of the ester phase, but also improving the phase separation efficiency. This structure increases the residence time through multi-stage deceleration, further reducing the backmixing phenomenon and improving the phase separation efficiency. By reducing the temperature to reduce the volatilization of ethyl acetate, the concentration of the ester phase is increased to solve the problems of the common phase separator for ethyl acetate synthesis. When the mixture enters the phase separator, if the flow rate is too fast or there is no appropriate deceleration mechanism, turbulence may be formed, resulting in backmixing. And if the residence time of the mixture in the phase separator is too short, the two phases may not be fully layered, leading to frequent backmixing phenomena, not only reducing the concentration of the ester phase, but also affecting the phase separation efficiency.,
