Description

Technical Field

[0001] This utility model relates to the field of glycerol ester preparation technology, and in particular to a condensation device in the glycerol ester preparation process. Background Technology

[0002] Glycerides are ester compounds formed by the esterification reaction of glycerol and fatty acids. Triacetylglycerol is a typical example of glycerides. It is a liquid at room temperature and is used in the chemical and pharmaceutical fields as a solvent and plasticizer. The core of the preparation of triacetylglycerol is the esterification reaction of glycerol and acetic acid. The reaction needs to be carried out at high temperature. In the preparation of triacetylglycerol, the boiling point of water is much lower than the required reaction temperature. Water will continue to evaporate in the form of vapor. The esterification reaction is a reversible reaction. The generated water will inhibit the forward reaction. The condensation equipment can stabilize the reaction temperature within a reasonable range, cool the evaporated water vapor into liquid and discharge it, thereby improving the yield of triacetylglycerol.

[0003] Early glycerol ester condensation equipment mainly consisted of a single straight condenser tube and an outer cooling jacket. The condenser tube, as the core heat exchange component, carried the gaseous substance to be condensed inside, while the outer jacket was circulated with cooling water to achieve heat exchange. Due to the limited heat exchange area of ​​a single tube, the high-boiling-point glycerol ester vapor was not fully condensed, resulting in high raw material volatilization losses. To solve these problems, existing equipment has been gradually optimized into a shell-and-tube heat exchange structure, which increases the heat exchange area and improves condensation efficiency through multiple tube bundles. However, in actual use, since the condensed liquid is a mixture of water and glycerol ester, and the mixture is not treated for stratification, it is directly discharged, resulting in waste of raw materials and failing to meet the needs of users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a condensation device in the preparation process of glycerides, which aims to improve the problem of raw material loss caused by the direct discharge of the condensed mixture without stratification treatment in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a condensation device in the preparation process of glycerides, comprising a cooling tank, a separation mechanism at the bottom of the cooling tank, a connecting mechanism on the upper and lower sides of the outer wall of the cooling tank, and an air inlet hood at the top of the cooling tank; The separation mechanism includes a separation tank, a flow guide shroud fixedly connected to the top of the inner wall of the separation tank, a liquid collection pipe connected to the bottom of the separation tank, a conical top cover fixedly connected to the top of the liquid collection pipe penetrating the bottom of the separation tank, an inlet groove opened on the front side of the outer wall of the liquid collection pipe, a spiral guide plate fixedly connected to the inner wall of the cooling tank, and a return pipe connected to the front side of the bottom of the cooling tank.

[0006] As a further description of the above technical solution: The connecting mechanism includes two fixing rings. The inner walls of the two fixing rings are fixedly connected to the upper and lower sides of the outer wall of the cooling tank, respectively. A rotating ring is rotatably connected to the opposite side of the two fixing rings. Multiple slots are provided on the inner walls of the two fixing rings and the rotating rings. Multiple locking blocks are fixedly connected to one side of the outer wall of the separator and the air inlet shroud. Connecting pieces are fixedly connected to the front side of the outer walls of the two fixing rings and the rotating rings. Bolts are provided on the front side of the outer walls of the two rotating rings. The outer walls of the two bolts are threadedly connected to the inner walls of the corresponding connecting pieces. A heat exchange assembly is provided inside the cooling tank.

[0007] As a further description of the above technical solution: The heat exchange assembly includes multiple heat exchange tubes, the bottom of which penetrates the top of the cooling tank. A water inlet pipe is connected to the bottom left side of the outer wall of the cooling tank, and a water outlet pipe is connected to the top right side of the outer wall of the cooling tank.

[0008] As a further description of the above technical solution: The upper and lower ends of the cooling tank are fixedly connected with sealing rings, and the adjacent side of the separation tank and the air inlet shroud are provided with grooves.

[0009] As a further description of the above technical solution: A fixing ring is fixedly connected to the middle of the inner wall of the air intake shroud, and a guide fan is fixedly connected to the inner wall of the fixing ring.

[0010] As a further description of the above technical solution: Limiting posts are fixedly connected to the bottom of the inner wall of the air intake hood, and the bottom of the multiple limiting posts are rotatably connected to limiting plates.

[0011] As a further description of the above technical solution: A support frame is fixedly connected to the bottom of the outer wall of the cooling tank, and a shock-absorbing pad is fixedly connected to the bottom of the support frame.

[0012] As a further description of the above technical solution: The inner dimensions of the spiral guide plate match the outer dimensions of the liquid collecting pipe, and the outer dimensions of the separation tank and the air inlet cover match the inner dimensions of the corresponding fixing rings. The multiple locking blocks engage with their respective locking slots.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after steam enters the cooling tank from the air inlet hood, it condenses into liquid. The liquid falls due to gravity. The denser triacetin falls along the spiral guide plate and flows to the outside of the spiral under the action of centrifugal force. It is then returned to the outside of the spiral for reuse through the return pipe. The less dense water gathers towards the center of the spiral. When it flows to the liquid inlet tank, it enters the liquid collection pipe through the tank opening and is finally discharged from the separation tank. The layered treatment reduces the loss of raw materials.

[0014] 2. In this utility model, by engaging the locking block of the separator tank and the outer wall of the air intake hood with the locking groove of the fixing ring, rotating the rotating ring causes the locking groove on the inner wall of the rotating ring to be misaligned with the locking block. Then, the bolt passes through the connecting piece between the fixing ring and the rotating ring and is tightened to complete the fixation. When disassembling, loosen the bolt and rotate the rotating ring in the opposite direction to disengage the locking block from the locking groove, thereby realizing the quick disassembly and installation of the separator tank, the air intake hood and the cooling tank, which is convenient for cleaning and maintenance.

[0017] 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.

[0018] Reference Figure 2 and Figure 3 An embodiment of this utility model is provided: a condensation device in the preparation process of glycerides, including a cooling tank 1, a separation mechanism 2 at the bottom of the cooling tank 1, a connecting mechanism 4 on the upper and lower sides of the outer wall of the cooling tank 1, and an air inlet hood 3 at the top of the cooling tank 1. The separation mechanism 2 includes a separation tank 201, which receives the condensate flowing from the cooling tank 1 and provides a closed space for liquid stratification. A guide shroud 202 is fixedly connected to the top of the inner wall of the separation tank 201. The guide shroud 202 collects and gathers the condensate falling from the cooling tank 1. A collection pipe 203 is connected to the bottom of the separation tank 201. The collection pipe 203 is a discharge channel for low-density water. The top of the collection pipe 203 penetrates the bottom of the separation tank 201 and is fixedly connected to a conical top cover 205. The conical top cover 205 evenly distributes the condensate collected by the guide shroud 202. The liquid is dispersed onto the surface of the spiral guide plate 206. An inlet groove 204 is provided on the front side of the outer wall of the liquid collecting pipe 203. Low-density water converges towards the center in the spiral flow and enters the liquid collecting pipe 203 through the inlet groove 204. The spiral guide plate 206 is fixedly connected to the inner wall of the cooling tank 1. The spiral guide plate 206 is used to extend the liquid flow path and use the centrifugal force generated by the spiral motion to separate liquids of different densities. A return pipe 207 is connected to the front side of the bottom of the cooling tank 1. The return pipe 207 is used to recover the separated triacetylglycerol to avoid residue waste and improve the utilization rate of raw materials. The inner dimensions of the spiral guide plate 206 match the outer dimensions of the liquid collection pipe 203. The outer dimensions of the separator 201 and the air inlet hood 3 match the inner dimensions of the corresponding fixing rings 401. Multiple locking blocks 404 engage with the corresponding locking slots 403. Specifically, after steam enters the cooling tank 1 through the air inlet hood 3, it is buffered and guided by the flow guide fan 8 to prevent the airflow from directly impacting the filter screen 11. The airflow then passes through the filter screen 11, where it intercepts large particulate impurities. The purified steam exchanges heat with the cooling medium in the cooling tank 1 and condenses into a liquid. The liquid falls to the flow guide hood 202 at the top of the separator 201 under the action of gravity. It is then evenly dispersed onto the spiral guide plate 206 by the conical top cover 205. The spiral guide plate 206 forms a spiral downward channel in the separator 201, extending the flow path of the liquid. The denser triacetin flows to the outside of the spiral under the action of centrifugal force and converges downward along the plate surface to the bottom of the separator 201. Finally, it is returned through the return pipe 207 and reused. The less dense water gathers towards the center of the spiral. When it flows to the position of the liquid inlet trough 204, it enters the liquid collection pipe 203 through the trough opening and is finally discharged from the separator 201.

[0019] Reference Figure 1 , Figure 3 and Figure 4 The connecting mechanism 4 includes two fixing rings 401, which provide positioning slots 403 for the locking block 404. The inner walls of the two fixing rings 401 are fixedly connected to the upper and lower sides of the outer wall of the cooling tank 1, respectively. A rotating ring 402 is rotatably connected to the opposite side of the two fixing rings 401. The rotating ring 402 rotates to misalign its own slot 403 with the slot 403 of the fixing ring 401, thereby firmly locking the locking block 404 of the separation tank 201 and the air intake shroud 3, achieving radial limiting. Multiple slots are provided on the inner walls of the two fixing rings 401 and the rotating ring 402. 403, multiple locking blocks 404 are fixedly connected to one side of the outer wall of the separator tank 201 and the air inlet hood 3. Connecting pieces 405 are fixedly connected to the front side of the outer wall of the two fixing rings 401 and the rotating ring 402. Bolts 406 are provided on the front side of the outer wall of the two rotating rings 402. The outer wall of the two bolts 406 is threaded to the inner wall of the corresponding connecting piece 405. By tightening the bolts 406, the rotating ring 402 and the fixing ring 401 are fixed to prevent the locking blocks 404 from falling off due to the loosening of the rotating ring 402. A heat exchange component 407 is provided inside the cooling tank 1. The heat exchange assembly 407 includes multiple heat exchange tubes 4071. Steam to be condensed flows inside the heat exchange tubes 4071, transferring the heat of the steam to the external cooling medium, causing the steam to condense into liquid. The bottom of the multiple heat exchange tubes 4071 all penetrate the top of the cooling tank 1. The bottom left side of the outer wall of the cooling tank 1 is connected to the water inlet pipe 4072, and the top right side of the outer wall of the cooling tank 1 is connected to the water outlet pipe 4073. The water inlet pipe 4072 and the water outlet pipe 4073 form a counter-current heat exchange path with the water inlet at the bottom and the water outlet at the top. Specifically, steam flows within the heat exchange tube 4071, while cooling water flows in through the inlet pipe 4072 at the bottom left side of the cooling tank 1 and flows out through the outlet pipe 4073 at the top right side of the cooling tank 1, forming counter-current heat exchange to ensure steam condensation. When glycerol ester residue or scale accumulates on the inner wall of the heat exchange tube 4071 due to prolonged use, affecting heat exchange efficiency and requiring cleaning and disassembly, during installation, the locking block 404 on the outer wall of the separator tank 201 and the air inlet hood 3 are aligned with the locking groove 403 of the fixing ring 401 and secured. Insert the ring 402 and then rotate it to offset the position of the slot 403 and the block 404 on the inner wall of the ring 402, thus creating a limit to prevent the separator 201 and the air intake hood 3 from falling off. The bolt 406 is passed through the connecting piece 405 between the fixing ring 401 and the rotating ring 402 and tightened to complete the fixation. When disassembling, loosen the bolt 406 and rotate the rotating ring 402 in the opposite direction to allow the block 404 to disengage from the slot 403, thereby achieving the quick separation of the separator 201, the air intake hood 3 and the cooling tank 1, which is convenient for cleaning and maintenance.

[0020] Reference Figure 1 , Figure 4 and Figure 5 The upper and lower ends of the cooling tank 1 are fixedly connected with sealing rings 5, which form a sealing strip to prevent steam from leaking from the connection gap. Grooves 6 are provided on the adjacent side of the separator 201 and the air intake hood 3. A fixing ring 7 is fixedly connected to the middle of the inner wall of the air intake hood 3. The fixing ring 7 is used to fix the guide fan 8. The guide fan 8 is fixedly connected to the inner wall of the fixing ring 7. The guide fan 8 converts the steam entering the air intake hood 3 into a spiral airflow, reducing the direct impact force on the filter screen 11. Four... A limiting post 9 is fixedly connected to the filter screen 11. The limiting post 9 provides vertical guidance for the filter screen 11. The bottom of the multiple limiting posts 9 is rotatably connected to a limiting plate 10. The limiting plate 10 supports the filter screen 11 from the bottom. The filter screen 11 is provided at the bottom of the inner wall of the air intake hood 3. The filter screen 11 intercepts large particulate impurities carried in the steam. The outer wall of the filter screen 11 is slidably connected to the corresponding limiting post 9 on all four sides. A support frame 12 is fixedly connected to the bottom of the outer wall of the cooling tank 1. A shock-absorbing pad 13 is fixedly connected to the bottom of the support frame 12. Specifically, the sealing rings 5 ​​at the upper and lower ends of the cooling tank 1 cooperate with the grooves 6 on the adjacent sides of the separator 201 and the air inlet hood 3 to form a seal, preventing steam from leaking from the connection gap. When steam enters the air inlet hood 3, it forms a spiral airflow through the blades of the guide fan 8, avoiding direct impact on the filter screen 11. The filter screen 11 is supported by the bottom limiting plate 10. When installing the filter screen 11, move the filter screen 11 upward along the limiting post 9, and then rotate the limiting plate 10 to form support at the bottom of the filter screen 11. When cleaning the filter screen 11, rotate the limiting plate 10 in the opposite direction to remove the filter screen 11. The support frame 12 at the bottom of the cooling tank 1 is used to distribute the weight of the equipment, and the bottom shock-absorbing pad 13 absorbs the vibration during operation to ensure the stability of long-term operation.

[0021] Working principle: After steam enters the cooling tank 1 from the air inlet hood 3, it is buffered and guided by the guide fan 8 to avoid direct airflow impact. Then the airflow passes through the filter screen 11 to intercept large particulate impurities. The purified steam exchanges heat with the cooling medium in the cooling tank 1 and condenses into a liquid mixture. The liquid falls to the guide hood 202 at the top of the separator 201 under gravity. It is evenly dispersed onto the spiral guide plate 206 through the conical top cover 205. The spiral guide plate 206 forms a spiral downward channel in the separator 201, extending the liquid flow path. The denser triacetin flows to the outside of the spiral under the action of centrifugal force and converges downward along the plate surface to the bottom of the separator 201. Finally, it is returned to the bottom through the return pipe 207 for reuse. The less dense water gathers towards the center of the spiral. When it flows to the liquid inlet trough 204, it enters the liquid collection pipe 203 through the trough opening and is finally discharged from the separator 201. Steam flows within heat exchange tube 4071, while cooling water flows in from the inlet pipe 4072 at the bottom left side of cooling tank 1 and flows out from the outlet pipe 4073 at the top right side of cooling tank 1, forming counter-current heat exchange to ensure steam condensation. When the inner wall of heat exchange tube 4071 accumulates glycerol residue or scale due to long-term use, affecting heat exchange efficiency and requiring cleaning and disassembly, during installation, align the locking block 404 on the outer wall of the separator tank 201 and the air inlet shroud 3 with the locking groove 403 of the fixing ring 401 and engage it, then rotate the rotating ring. 402, causing the slot 403 on the inner wall of the rotating ring 402 to misalign with the locking block 404, forming a limit to prevent the separator tank 201 and the air intake cover 3 from falling off. Finally, the bolt 406 passes through the connecting piece 405 between the fixing ring 401 and the rotating ring 402 and is tightened to complete the fixation. When disassembling, simply loosen the bolt 406 and rotate the rotating ring 402 in the opposite direction to allow the locking block 404 to disengage from the slot 403, realizing the quick separation of the separator tank 201, the air intake cover 3 and the cooling tank 1, which is convenient for cleaning and maintenance.
