Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to a novel liquid collection tray. Background Technology

[0002] Mixed fatty acids refer to fatty acids composed of various fatty acid monomers, including hexadecimal saturated fatty acids with a freezing point of 63°C, octadecanoic saturated fatty acids with a freezing point of 72°C, and low-carbon fatty acids with freezing points between 20°C and 63°C. The raw materials for the production of mixed fatty acids are mainly derived from natural oils, such as palm oil, which, after refining, yields edible oil with a freezing point of 24°C and a mixture of fatty acids containing impurities. Therefore, it is necessary to fractionate the mixed fatty acids using fatty acid production equipment.

[0003] The applicant designed a fatty acid production device, including a distillation kettle containing a fatty acid mixing zone and a distillation column located above the distillation kettle. The distillation column has packing material, and a vertical shell-and-tube condenser is located above the packing material. The shell-and-tube condenser includes a shell and condensing tubes inside the shell. Coolant is installed between the condensing tubes and the shell. A collection tray is placed below the condensing tubes. The collection tray is connected to an external collector. The fatty acid mixture in the distillation kettle is heated to form high-temperature vapor, which rises through the packing material and enters the condensing tubes in the condenser for condensation. The condensed fatty acid, which is then liquid, falls and flows into the collection tray, and is then collected in the collector.

[0004] like Figure 10 As shown, the liquid collecting tray is installed inside the distillation column, and an annular plate is installed inside the distillation column, which overlaps the liquid collecting tray. The liquid collecting tray includes a tray body and conduits. The tray body has through holes running vertically through it. Each conduit is inserted into the corresponding through hole and forms an interference fit with the through hole. The conduits extend upward beyond the upper end face of the liquid collecting tray to form a liquid collecting section. High-temperature vapor can pass upward through the conduits and enter the shell and tube condenser. The condensed liquid fatty acids will fall into the various liquid collecting sections in the tray body. However, this type of liquid collecting tray has shortcomings.

[0005] The catheter is inserted into the through hole on the disc to form an interference fit, which makes the assembly process relatively complicated and it is prone to loosening after long-term use.

[0006] To maintain gas flow, the upper end of the conduit is open. However, after the liquid fatty acids fall, a small portion of the liquid fat can easily fall back into the distillation vessel through the opening of the conduit.

[0007] To facilitate the disassembly and assembly of the collection tray, there is a gap between the inner wall of the distillation column and the collection tray, and there is a height difference between the lower end of the condenser tube and the tray body. The liquid fatty acids have a high gravitational potential energy when falling, and the impact force on the tray body after falling into the tray body is large. This makes it easy for the liquid fatty acids to spread in all directions and splash onto the inner wall of the distillation column, and then flow downward into the gap between the inner wall of the distillation column and the collection tray, affecting the collection efficiency. Summary of the Invention

[0008] This invention provides a novel liquid collection tray. The upper end of the tray is integrally formed with a gas guide pipe corresponding to multiple through holes, preventing the gas guide pipe from loosening after long-term use. Furthermore, a support part and a cone with multiple ribs are provided at the upper opening of the gas guide pipe. This liquid collection tray allows gas to pass upward through the through groove between two adjacent support parts, ensuring that after the liquid fatty acid falls, it can fall onto the ribs of the cone and be divided into multiple liquid streams, reducing the potential energy of the liquid fatty acid when falling and improving the collection efficiency of fatty acid.

[0009] The technical solution of this utility model is implemented as follows:

[0010] A novel liquid collection tray includes a tray body for installation below multiple condenser tubes. The tray body has multiple through holes that are vertically continuous and correspond one-to-one with the positions of the condenser tubes. Multiple gas guide tubes, each corresponding to one-to-one with the positions of the through holes, are integrally formed at the upper end of the tray body. The inner diameter of the gas guide tubes is greater than or equal to the inner diameter of the through holes. A liquid collection area for receiving liquid fatty acids is formed between the multiple gas guide tubes. Multiple circumferentially spaced support portions are provided at the upper openings of the gas guide tubes. A through groove is formed between every two adjacent support portions to allow gas to pass upwards. A conical body for receiving liquid fatty acids is connected to the upper end of the support portion. The conical body has a conical liquid guiding surface. Multiple ribs are evenly distributed circumferentially on the conical liquid guiding surface. Each rib extends obliquely in the longitudinal direction, and a flow guide groove is formed between every two adjacent ribs. The multiple ribs can buffer the falling liquid fatty acids and divide the falling liquid fatty acids into multiple streams that flow downwards into the liquid collection area along the flow guide groove.

[0011] Preferably, the lower end of the cone has a bottom surface, and an inverted cone is connected to the bottom surface. The inverted cone has an inverted conical air guiding surface, which can guide the rising gas outward through the channel, allowing the high-temperature mixed vapor to quickly rise and pass through the liquid collecting plate.

[0012] Preferably, the top of the inverted cone has a top surface that connects with the bottom surface of the cone, and the top surface is surrounded by the bottom surface; thereby preventing the falling liquid fatty acids from contacting the inverted cone air guide surface, allowing the liquid fatty acids to fall smoothly into the collection tray.

[0013] Preferably, the conical and inverted conical shapes are closed hollow structures; this ensures the collection tray is lightweight and low-cost.

[0014] Preferably, both the cone-shaped body and the inverted cone-shaped body are conical or pyramidal structures.

[0015] Preferably, the disc body includes a base and an integrally formed retaining portion at the bottom edge, the retaining portion extending upward beyond the top of the disc body to prevent liquid fatty acids falling into the collection area from overflowing.

[0016] Preferably, the upper opening of the gas duct extends upward beyond the enclosure to prevent liquid fatty acids from the collection area from flowing back into the gas duct.

[0017] Preferably, the support is a rod-shaped structure, and the number of supports is one.

[0018] Preferably, the prism is triangular or trapezoidal, and the cross-sectional area of ​​the prism gradually decreases from top to bottom. This ensures that when a small portion of the liquid fatty acids flows downwards under gravity, the contact area with the prism becomes smaller and smaller, and they gradually enter the guide channel, improving the collection efficiency of the liquid collection tray.

[0019] The beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0020] Multiple air guide tubes are integrally formed with the upper part of the disc body, eliminating the need for inserting the air guide tubes into the through holes and ensuring the durability of the disc body.

[0021] The conical liquid guiding surface on the cone-shaped body can prevent liquid fatty acids from falling into the upper opening of the gas guide tube and prevent liquid fatty acids from flowing back into the distillation vessel; at the same time, the ridge plate on the conical liquid guiding surface can cut the falling liquid fatty acids into multiple liquid streams, which is equivalent to buffering the falling liquid fatty acids, reducing the potential energy of the falling liquid fatty acids, and preventing the liquid fatty acids from splashing out of the plate after falling; thus ensuring the collection efficiency of fatty acids.

[0022] Because the contact area between the cut liquid stream and the conical liquid guiding surface is small, multiple liquid streams can flow smoothly downward into the liquid collection area without sticking to the conical liquid guiding surface. Attached Figure Description

Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] This utility model has multiple embodiments, and the specific implementation methods are as follows:

[0037] Example 1: As Figure 1-8 As shown, this embodiment provides a fatty acid production device, in which a novel liquid collection tray is used. The device includes:

[0038] The distillation assembly includes a distillation vessel 1, and a distillation column 2 pre-filled with packing 3 installed at the upper end of the distillation vessel 1. The distillation column 2 is connected to the distillation vessel 1. The high-temperature mixed vapor containing mixed fatty acids generated by heating the fatty acid mixture rises and passes through the packing 3. The packing 3 consists of multiple corrugated plates tightly arranged and clamped by a ring. The ring is fixedly installed inside the distillation column 2. The packing 3 can make the flow of the rising high-temperature mixed vapor more uniform.

[0039] The vertical condenser assembly 4 is connected to the packing 3. The vertical condenser assembly 4 includes multiple shell-and-tube condensers 41 arranged longitudinally. Each shell-and-tube condenser 41 includes a shell, within which one or more vertically extending condenser tubes 42 are located. Cooling channels 43, allowing coolant flow, are formed between the condenser tubes 42 and the shell, and are isolated from the condenser tubes 42. The condenser tubes 42 in every two adjacent shell-and-tube condensers 41 are interconnected and correspond one-to-one. Specifically, in this embodiment, interconnection means that the upper and lower shells are fixedly connected and the condenser tubes 42 correspond one-to-one, with space remaining between the upper and lower condenser tubes 42. From bottom to top, the condensation temperature of the multiple shell-and-tube condensers 41 decreases progressively, with the topmost shell-and-tube condenser 41 being the final stage. The condenser, specifically the condenser tube 42 of the final stage condenser, is connected to a vacuum pump 5. The vacuum pump 5 is connected to the condenser tube 42 of the final stage shell-and-tube condenser via a connecting pipe 51, providing a vacuum environment for the fatty acid production process to improve production efficiency. When the vacuum pump 5 is working, it can draw high-temperature mixed vapor through the packing 3 and gradually move it from bottom to top through multiple shell-and-tube condensers 41, causing the fatty acids at the corresponding condensation points to condense into liquid and then flow downwards out of the corresponding condenser tube 42 under gravity. This segmented condensation structure allows the gaseous fatty acids sufficient condensation time, and the condensed liquid fatty acids flow out of the condenser tube 43 quickly after condensation, preventing the liquid fatty acids from condensing inside the tube wall of the condenser tube 43, reducing the probability of blockage of the vacuum pump 5 or the connecting pipe 51, and improving production efficiency.

[0040] A collection device for collecting liquid fatty acids flowing out of condenser 42.

[0041] Furthermore, in this embodiment, the vertical condenser assembly 4 has three shell-and-tube condensers 41, forming three condensation zones with different condensation temperatures. To ensure that the condensed liquid fatty acids overcome atmospheric pressure and flow stably downwards, the longitudinal length of the condenser tubes 42 in the lowermost and middle shell-and-tube condensers 41 is 1500 mm, and the longitudinal length of the condenser tubes 42 in the uppermost shell-and-tube condenser 41 ranges from 1000 mm to 1500 mm. For example, in a practical application, the high-temperature mixed steam may contain octadecanoic saturated fatty acids with a condensation point of 72°C, hexadecanoic saturated fatty acids with a condensation point of 63°C, and low-carbon fatty acids with condensation points below 63°C. As the steam passes through the three shell-and-tube condensers 41 from bottom to top, the octadecanoic saturated fatty acids condense into liquid in the bottommost shell-and-tube condenser 41, the hexadecanoic saturated fatty acids condense into liquid in the middle shell-and-tube condenser 41, and the low-carbon fatty acids condense into liquid in the topmost shell-and-tube condenser 41. Since the condenser tubes 42 are interconnected and of sufficient length, these liquid fatty acids can all overcome the supporting force of atmospheric pressure and flow downwards under the action of gravity. In actual production, this method can greatly reduce the clogging frequency of the vacuum pump 5. The vacuum pump 5 and connecting pipe 51, which originally needed to be cleaned every 2-3 days, now only need to be cleaned once every 15 days or more, reducing the downtime frequency during fatty acid production and improving production efficiency.

[0042] Furthermore, each shell-and-tube condenser 41 is equipped with an inlet pipe 45 and an outlet pipe 46 that communicate with the cooling channel 43. In this embodiment, to achieve different condensation temperatures in the multiple shell-and-tube condensers 41 for condensing fatty acid monomers with different freezing points, in addition to supplying coolant of different temperatures to the cooling channels 43 of the shell-and-tube condensers 41 at different locations, this embodiment also provides a more ingenious structural design. Specifically, in every two adjacent shell-and-tube condensers 41, the outlet pipe 46 of the upper shell-and-tube condenser 41 is connected to the inlet pipe 45 of the lower shell-and-tube condenser 41. Specifically, the outlet pipe 46 of the upper shell-and-tube condenser 41 and the inlet pipe 45 of the lower shell-and-tube condenser 41 are sealed together by a connecting rigid pipe 421. The inlet pipe 45 of the final-stage shell-and-tube condenser is connected to a conveying device, which includes a storage tank 451 connected to the inlet pipe 45. To facilitate coolant delivery, a pressurizing component such as a gear pump (not shown) can be installed between the storage tank 451 and the inlet pipe 45. Coolant is introduced into the inlet pipe 45 of the final stage condenser. After heat exchange with the high-temperature mixed vapor in the corresponding condenser tube 42, the coolant temperature rises and flows downward into the cooling channel 43 of the next shell-and-tube condenser 41, circulating repeatedly until the coolant flows out from the outlet pipe 46 of the bottom shell-and-tube condenser 41, ensuring that the condensation temperature of the multiple shell-and-tube condensers 41 decreases step by step from bottom to top. By connecting the cooling channels of each shell-and-tube condenser to each other, the coolant flows from top to bottom through each shell-and-tube condenser, making each shell-and-tube condenser form different condensation temperatures, so as to condense fatty acid monomers with different condensation points into liquid. This design saves coolant costs and makes multiple condensation units form different condensation temperatures, which is ingenious and achieves two goals at once.

[0043] Furthermore, if the coolant directly flows through the cooling channels 43 of each shell-and-tube condenser 41 sequentially, insufficient heat exchange may occur due to excessive flow rate, causing the condensation temperatures of each shell-and-tube condenser 41 to tend to be the same, making it difficult to form condensation zones with different condensation temperatures. Therefore, the cooling channels 43 of the shell-and-tube condenser 41 have multiple baffles 44. The baffles 44 can be welded and fixed to the outer wall of the condenser tube 42 or to the inner wall of the shell. The baffles 44 reduce the downward flow speed of the coolant, allowing the coolant to fully exchange heat with the high-temperature mixed vapor in the corresponding shell-and-tube condenser 41 before flowing downward into the next cooling channel 43. This prevents the coolant from flowing too quickly into the cooling channels 43 of the next shell-and-tube condenser 41, ensuring the efficiency of fatty acid production.

[0044] Furthermore, after condensation, most of the liquid fatty acids will flow downwards out of the condenser tube 43, but some liquid fatty acids may still remain on the inner wall of the condenser tube 43. Therefore, in this embodiment, at least one shell-and-tube condenser 41 is equipped with a heating tube that communicates with the cooling channel 43. High-temperature heating steam can be introduced into the heating tube to make the liquid fatty acids condensed on the condenser tube 42 flow downwards out of the corresponding shell-and-tube condenser 41's condenser tube 42; thus avoiding some liquid fatty acids remaining on the inner wall of the condenser tube and further improving the production efficiency.

[0045] Furthermore, such as Figure 3-4 As shown, the collection device in this embodiment includes a collection tray located between the vertical condenser assembly 4 and the packing 3 for collecting liquid fatty acids. The collection tray is connected to an external collector 78a. Specifically, an overlapping ring (not shown) is fixedly connected to the inner wall of the distillation column 2, and the collection tray overlaps and is fixed to the upper end of the overlapping ring. A collection pipe 79a is connected to the collection tray, and the collection pipe 79a is connected to an external collector 78a. To allow the liquid fatty acids to overcome atmospheric pressure and flow downwards into the collector 78a, the longitudinal length of the collection pipe 79a is not less than 13m. To facilitate the collection of liquid fatty acids, also... A gear pump can be installed between the collecting pipe 79a and the collector 78a for evacuation; the liquid collecting tray includes a tray body 7, on which multiple through holes 71 are provided at intervals; a gas guide pipe 73 corresponding to the position of the through holes 71 is installed at the upper end of the liquid collecting tray 7, and the gas guide pipe 73 allows high-temperature mixed vapor to pass upward; a liquid collecting area 72 is formed between the multiple gas guide pipes 73, and the liquid fatty acids in each shell-and-tube condenser 41 reach the liquid collecting area 72 under the action of gravity, and then enter the collector 78a; so that the various fatty acid monomers are condensed into liquid and then flow into the collector, preventing the liquid fatty acids from flowing back to the distillation kettle 1.

[0046] Furthermore, after the liquid fatty acids fall, a small portion of the liquid fat easily falls back into the distillation vessel through the opening of the conduit. Additionally, to facilitate the assembly and disassembly of the collection tray, there is a gap between the inner wall of the distillation column 2 and the collection tray. There is also a height difference between the lower end of the condenser tube 42 of the lowest shell-and-tube condenser 41 and the collection tray. The liquid fatty acids have a high gravitational potential energy when falling, resulting in a large impact force on the tray body 7 after falling into it. This easily causes the liquid fatty acids to spread in all directions and splash onto the inner wall of the distillation column before flowing downwards into the gap between the inner wall and the collection tray. To avoid this phenomenon, in this embodiment, the positions of the gas guide pipe 73 of the collection tray 7 correspond one-to-one with the upper condenser tube 42, and the upper opening of the gas guide pipe 73 is provided with multiple circumferentially spaced supports. The support 74 has a channel 77 between each two adjacent support 74 that allows gas to pass upward. The upper end of the support 74 is connected to a cone-shaped body for receiving liquid fatty acids. The cone-shaped body is provided with a cone-shaped liquid guiding surface 76. Multiple ribs 78 are evenly distributed along the circumference of the cone-shaped liquid guiding surface 76. Each rib 78 extends obliquely along the longitudinal direction. A guide channel 79 is formed between each two adjacent ribs 78. The multiple ribs 78 can buffer the falling liquid fatty acids and divide the falling liquid fatty acids into multiple streams that flow downward along the guide channel 79 into the liquid collection area 72. This not only slows down the falling speed of the liquid fatty acids but also prevents the liquid fatty acids from hanging on the cone-shaped liquid guiding surface 761, so that the falling liquid fatty acids can flow smoothly into the liquid collection area 72.

[0047] Furthermore, when the high-temperature mixed steam rises to the upper opening of the gas guide pipe 73, the cone-shaped body easily obstructs the steam. Therefore, in this embodiment, the lower end of the cone-shaped body has a bottom surface 761, and an inverted cone-shaped body is connected to the bottom surface 761. The inverted cone-shaped body has an inverted cone-shaped gas guide surface 77. The cross-sectional area of ​​the inverted cone-shaped gas guide surface 77 gradually increases from bottom to top. Therefore, the inverted cone-shaped gas guide surface 77 causes the rising gas to diffuse outward and exit through the channel 77, allowing the high-temperature mixed steam to quickly pass upward through the disc body 7.

[0048] Furthermore, to prevent the liquid fatty acids falling into the collection pan from flowing back into the distillation vessel 1 along the inverted conical air guide surface 77, the top of the inverted conical body has a top surface 771 that is connected to the bottom surface 761 of the conical body. The top surface 771 is surrounded by the bottom surface 761, thereby preventing the falling liquid fatty acids from contacting the inverted conical air guide surface 77 and allowing the liquid fatty acids to fall smoothly into the collection pan 1.

[0049] Furthermore, the cone-shaped and inverted cone-shaped bodies can be either conical or pyramidal structures. And to ensure the liquid collection tray is lightweight and low-cost, the cone-shaped and inverted cone-shaped bodies are closed hollow structures.

[0050] Furthermore, to ensure the receiving effect of the liquid collection tray, the tray body 7 includes a base and an integrally formed retaining part 7a at the bottom edge. The retaining part 7a extends upward beyond the upper end of the liquid collection tray 7 to prevent the liquid fatty acids falling into the liquid collection area 72 from overflowing. The upper opening of the air guide pipe 73 extends upward beyond the retaining part 7a to prevent the liquid fatty acids in the liquid collection area 72 from flowing back into the air guide pipe 73.

[0051] Furthermore, in this embodiment, the support portion 74 is a rod-shaped structure that occupies less space and facilitates the upward flow of gas. In addition, the number of support portions 74 should be within a reasonable range. If there are too many support portions 74, the width of the through groove 75 will become smaller, resulting in poor gas flow. If there are too few support portions 74, it will be difficult to provide stable support for the cone. Therefore, in this embodiment, the number of support portions 74 is in the range of 2-6, which takes into account both the structural stability of the cone and the smooth flow of gas.

[0052] Furthermore, when the falling liquid fatty acids come into contact with the prism plate 78, most of the liquid fatty acids will be broken down and enter the guide channel 79. However, a small portion of the liquid fatty acids will still remain on the prism plate 78. To avoid this phenomenon, in this embodiment, the prism plate 78 is triangular or trapezoidal, and the cross-sectional area of ​​the prism plate 78 gradually decreases from top to bottom. This makes the contact area between the small portion of liquid fatty acids and the prism plate 78 smaller and smaller as the liquid fatty acids flow downward under the action of gravity, and gradually enter the guide channel 79, thereby improving the collection efficiency of the liquid collection tray.

[0053] Furthermore, after the high-temperature mixed vapor passes through the condenser tube 42 of the lowest shell-and-tube condenser 41, the fatty acid monomers at the corresponding condensation point condense into a liquid state. However, the rising vapor easily carries a small amount of liquid droplets into the upper shell-and-tube condenser 41, where the condensation temperature is lower. At the lower condensation temperature, these droplets easily condense on the tube wall of the condenser tube 42, causing blockage. To isolate the droplets and ensure the smooth progress of the condensation process, such as... Figure 5-8As shown, a 500mm high installation space is left between every two adjacent vertical condenser tubes 42. A liquid-blocking assembly 6 is installed within this space to prevent liquid from condensing. The liquid-blocking assembly 6 includes an annular clamp and multiple vertically arranged, closely spaced corrugated wire meshes 61 within the clamp. Between two adjacent corrugated wire meshes 61, there are corrugated grooves 63 extending in a wavy shape. These grooves form a group that allows high-temperature mixed vapor to pass upwards. The corrugated wire meshes 61 have multiple mesh openings that can block the mixed liquid carried by the high-temperature mixed vapor below the corresponding condenser tube 42. This prevents the mixed vapor from carrying some liquid fatty acids into the condenser tubes of the upper shell-and-tube condenser after rising, thus avoiding the condensation of fatty acid monomers with higher condensation temperatures in the condenser tubes of the previous shell-and-tube condenser with lower condensation temperatures, ensuring the smooth progress of the fatty acid production process.

[0054] Furthermore, multiple wave-shaped wire meshes 61 constitute a wave-shaped wire mesh group, and multiple wave-shaped wire mesh groups arranged vertically are provided inside the annular clamp. To ensure the liquid-blocking effect, two layers of wave-shaped wire mesh groups are provided inside the annular clamp in this embodiment. If two adjacent wave-shaped groove groups are aligned with each other, the multiple wave-shaped wire meshes 61 can only form a single barrier for the liquid droplets in the high-temperature steam. Therefore, to provide a barriering effect, in this embodiment, every two adjacent wave-shaped groove groups are staggered to form multiple barriers for the mixed liquid carried by the rising high-temperature mixed steam, so as to block part of the liquid fatty acids in the mixed steam as much as possible.

[0055] Furthermore, to facilitate the installation of multiple corrugated wire meshes 61, the annular clamp includes multiple interlocking annular sub-clamps 62. Each annular sub-clamp 62 has a corresponding liquid-separating component 6 installed inside. Each annular sub-clamp 62 can rotate along the vertical axis and stop at a corresponding position to adjust the staggered angle of the two corrugated groove groups in two adjacent liquid-separating components 6. Specifically, one end of the annular sub-clamp 62 is provided with a flange ring 621. Multiple positioning holes 622 are evenly distributed circumferentially on the flange ring 621. The flange rings 621 of every two adjacent annular sub-clamps 62 are interlocked. After the corresponding annular sub-clamp 62 rotates to the predetermined position, the positioning holes 622 of the two adjacent flange rings 621 correspond one-to-one and are locked with screws. To facilitate installation, an overlapping ring plate is installed on the inner wall of the distillation column 2. The locked flange ring 621 can also be placed on the overlapping ring plate on the inner wall of the distillation column 2 for fixation.

[0056] Furthermore, the corrugated liquid barrier 61 is a corrugated wire mesh formed by multiple interlaced stainless steel wires, with the wire diameter ranging from 1.2mm to 1.8mm, to form fine liquid-blocking holes. The corrugated liquid barrier 61 includes multiple equally spaced bent sections, with a vertical unit perforated plate 611 formed between every two adjacent bent sections. To facilitate installation and ensure the liquid-blocking effect, the included angle between every two unit perforated plates 611 is 60°, and the vertical height of the unit perforated plate 611 ranges from 45mm to 60mm. In order to ensure that high-temperature steam can pass through while effectively blocking liquid droplets, in this embodiment, the mesh count of the liquid-blocking holes on the corrugated liquid barrier 61 ranges from 110 to 125, where mesh count refers to the number of liquid-blocking holes per square centimeter.

[0057] Furthermore, if the temperature of the corresponding condenser is still too high and does not meet the requirements after the coolant in the last-stage shell-and-tube condenser flows downward into the next shell-and-tube condenser, it is necessary to increase the coolant flow rate. Specifically, the temperature sensing element 49 is installed at the outlet pipe 46 of the last-stage condenser. A condensing temperature regulating component is installed on the vertical condensing assembly 4. The condensing temperature regulating component includes a controller and a temperature sensing element 49. The temperature sensing element 49 is usually a thermometer electrically connected to the controller. The last-stage shell-and-tube condenser supplies coolant to the inlet pipe 45 through a conveying device. The conveying device includes a liquid storage tank 451 and a power transmission component. The power transmission component can be a motor (not shown) electrically connected to the controller. The motor is usually connected to a gear pump (not shown). (See diagram) The transmission connects and delivers coolant to the cooling channel 43 of the final shell-and-tube condenser; the controller is electrically connected to the temperature detection element 49 and the coolant delivery device; the temperature detection element 49 detects the cooling temperature and sends a detection signal back to the controller, which then determines whether to control the coolant delivery device to increase the coolant delivery rate based on the detection signal; for example, when the temperature detection element 49 detects that the condensation temperature in the corresponding shell-and-tube condenser 41 meets the standard, the temperature detection element 49 will not send a signal to the controller, allowing the coolant to enter the cooling channel of the final shell-and-tube condenser at a normal rate; when the temperature detection element 49 detects that the condensation temperature in the corresponding shell-and-tube condenser 41 does not meet the standard, it will send a signal to the delivery device to increase the coolant delivery rate, so that the condensation temperature in each shell-and-tube condenser is stable.

[0058] Furthermore, in addition to increasing the coolant flow rate to the final-stage shell-and-tube condenser, this embodiment can also control the condensing temperature through another design. Specifically, a condensing temperature regulating component is installed on the vertical condensing assembly 4. The condensing temperature regulating component includes a controller and a temperature sensing element 49. Except for the final-stage condenser, the temperature sensing element 49 is installed at the outlet pipe 46 position of each of the remaining shell-and-tube condensers 41. Each of the remaining shell-and-tube condensers 41 is also equipped with a replenishment pipe 48 connected to the corresponding cooling channel 43. A replenishment device 481 for replenishing coolant into the corresponding cooling channel 43 is connected to the replenishment pipe 48. The replenishment device 481 has a structure similar to the conveying device. The controller, temperature sensing element 49, and replenishment device 481 are also connected to the replenishment device. Device 481 is electrically connected; the temperature detection element 49 at the corresponding position detects the cooling temperature and feeds back the detection signal to the controller. The controller determines whether to control the corresponding liquid replenishment device 481 to replenish the corresponding cooling channel 43 based on the detection signal. For example, when the temperature detection element 49 detects that the condensing temperature in the corresponding shell-and-tube condenser 41 meets the standard, the temperature detection element 49 will not send a signal to the controller, and the liquid replenishment device will not work at this time. When the temperature detection element 49 detects that the condensing temperature in the corresponding shell-and-tube condenser 41 does not meet the standard, it will send a signal to the delivery device to make the liquid replenishment device work and pass the coolant into the corresponding shell-and-tube condenser 41, so that the condensing temperature in each shell-and-tube condenser 41 is in a stable state.

[0059] Example 2: This example differs from the previous examples in that the specific structure of the collection device is different. This collection device is suitable for collecting fatty acid monomers with high purity. Specifically, for example... Figure 9 As shown, the collection device includes multiple collection trays for collecting liquid fatty acids, each collection tray being located below a corresponding shell-and-tube condenser; each collection tray is connected to an external collector 78a; the liquid fatty acids in each shell-and-tube condenser 41 flow downwards from the corresponding condenser tube 42 under gravity and reach the corresponding collection area 72, and then flow into the corresponding collector 78a; this allows different monomeric fatty acids to flow into the corresponding collectors, thereby collecting the liquid fatty acids and also increasing the purity of each fatty acid monomer.

[0060] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
