Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to a novel liquid separation device. 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, octadecane 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. For example, after refining palm oil, one can obtain edible oil with a freezing point of 24°C and a mixture of fatty acids containing impurities. Therefore, it is necessary to separate the mixed fatty acids through fractional distillation.

[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 contains packing material, and above the packing material is a liquid collection tray that allows gas to pass through, and multiple vertical shell-and-tube condensers. Each shell-and-tube condenser includes a shell and condensing tubes inside the shell. Coolant is added between the condensing tubes and the shell. The condensing tubes between any two adjacent condensers are interconnected and correspond one-to-one. From bottom to top, the cooling temperature of the coolant in each condenser decreases progressively. The mixture in the distillation kettle is heated to form high-temperature vapor containing fatty acids. The high-temperature vapor rises and passes through the condensing tubes of each condenser in sequence, fractionating fatty acid monomers with different freezing points. The individual fatty acid monomers, condensed into liquid, flow downwards through their respective condensing tubes and into the liquid collection tray.

[0004] In the actual production process, after the high-temperature steam enters the condenser at the bottom, most of the gaseous fatty acids with the corresponding condensation point condense into liquid and flow downwards. However, the high-temperature steam flowing upwards will still carry a small portion of the liquid fatty acids that have already condensed and have a higher condensation point into the condenser at the top with a lower condensation temperature. This will cause the fatty acids that do not have time to condense and have a higher condensation point to be condensed together and condensed on the pipe wall of the upper condensation pipe, causing blockage of the condensation pipe and affecting the efficiency of fatty acid production.

[0005] Therefore, a liquid separator needs to be installed between the two shell-and-tube condensers. While ensuring that the gas passes upward and enters the condenser tube, it is necessary to block the small amount of condensed fatty acid droplets to prevent them from entering the upper condenser tube. Summary of the Invention

[0006] This invention provides a novel liquid-separating device. By setting multiple corrugated baffles in the annular sleeve, high-temperature steam passes upward through the corrugated groove between two corrugated baffles, while fatty acid droplets are blocked to the maximum extent in the multiple liquid-separating holes on the corrugated baffles. This prevents the liquid fatty acid droplets from condensing and clogging the condenser tube, thus ensuring the efficiency of fatty acid production.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A novel liquid-separating device includes an annular clamp with multiple liquid-separating components arranged vertically within it. Each liquid-separating component comprises multiple vertically and closely arranged corrugated liquid-separating elements, each corrugated liquid-separating element having multiple liquid-separating through holes for blocking liquid. A corrugated groove is formed between every two adjacent corrugated liquid-separating elements, allowing gas to rise and pass through. The multiple corrugated grooves form a corrugated groove group, and the corrugated groove groups in every two adjacent liquid-separating components are staggered to form multiple barriers to the liquid in the rising gas.

[0009] Preferably, the annular clamp includes multiple interlocking annular sub-clamps, each annular sub-clamp having a corresponding liquid-separating component installed inside. Each annular sub-clamp can rotate along the vertical axis and stop at a corresponding position to adjust the staggered angle of the two wave-shaped groove groups in the two adjacent liquid-separating components, thereby forming a corresponding liquid-separating effect for high-temperature mixed gases with different flow rates.

[0010] Preferably, one end of the annular ferrule is provided with a flange ring, and multiple positioning holes are evenly distributed along the circumference of the flange ring. The flange rings of every two adjacent annular ferrules are connected to each other. After the corresponding annular ferrule is rotated to the predetermined position, the positioning holes of the two adjacent flange rings correspond one-to-one and are locked with screws.

[0011] Preferably, the corrugated liquid separator includes multiple equally spaced bent sections, with a vertical unit orifice plate formed between every two adjacent bent sections, and the included angle between every two unit orifice plates is 60°.

[0012] Preferably, the mesh size of the liquid-blocking through-holes on the corrugated liquid-blocking component is in the range of 110-125; a reasonable mesh size ensures the liquid-blocking effect of the through-holes on the liquid droplets.

[0013] Preferably, the corrugated liquid barrier is formed by multiple stainless steel wires interlacing with each other.

[0014] Preferably, the stainless steel wire diameter ranges from 1.2 mm to 1.8 mm; a finer wire diameter can better form fine liquid-blocking pores.

[0015] As a preferred option, the annular clamp has two liquid-separating components arranged vertically; this ensures the liquid-separating effect while saving space as much as possible.

[0016] Preferably, the corrugated liquid separator is a corrugated plate with a plurality of liquid-separating through holes.

[0017] Preferably, the corrugated plate has multiple rows of liquid-blocking through holes spaced apart; from bottom to top, the diameter of the multiple liquid-blocking through holes gradually decreases, and the distance between two adjacent liquid-blocking through holes in the same row also gradually decreases; as the gas carrying fatty acid droplets flows upward, the corrugated liquid-blocking component has a better effect on blocking the droplets.

[0018] The beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0019] The annular sleeve of this invention comprises multiple vertically arranged liquid-separating components, each consisting of multiple corrugated baffles. These baffles have multiple spaced liquid-separating through-holes, and each pair of adjacent baffles has a corrugated groove. When the mixed gas rises, high-temperature steam can pass through the corrugated grooves. When fatty acid droplets in the high-temperature steam come into contact with the baffles, the droplets remain in the liquid-separating through-holes. Furthermore, the adjacent corrugated grooves are staggered, ensuring that even if a small number of fatty acid droplets pass through the lowest liquid-separating component without affecting the rise of the high-temperature steam, the upper liquid-separating component can again separate the droplets. This maximizes the protection against the fatty acid droplets rising with the high-temperature steam into the lower-temperature condenser tube, preventing the liquid fatty acid droplets from condensing and clogging the condenser tube, thus ensuring the efficiency of fatty acid production.

Detailed Implementation

[0029] 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.

[0030] 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.

[0031] This utility model has multiple embodiments, and the specific implementation methods are as follows:

[0032] Example 1: As Figure 1-5 , Figure 7-8 As shown, this embodiment provides a fatty acid production device, in which a liquid separator is applied. The device includes:

[0033] 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.

[0034] 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.

[0035] A collection device for collecting liquid fatty acids flowing out of condenser 42.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Furthermore, such as Figure 3-4 As shown, the collection device in this embodiment includes a collection tray 7 located between the vertical condenser assembly 4 and the packing 3 for collecting liquid fatty acids. The collection tray 7 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 7 overlaps and is fixed to the upper end of the overlapping ring. A collection pipe 79a is connected to the collection tray 7, 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... Liquid fatty acids can also be drawn from the collection tube 79a and the collector 78a by a gear pump. The collection plate 7 is provided with multiple through holes 71 that run vertically through it. A gas guide pipe 73 corresponding to the position of the through hole 71 is installed at the upper end of the collection plate 7. The gas guide pipe 73 allows high-temperature mixed vapor to pass upward. A collection area 72 is formed between the multiple gas guide pipes 73. Liquid fatty acids in each shell-and-tube condenser 41 reach the collection area 72 under the action of gravity, and then enter the collector 78a. This allows the various fatty acid monomers to be condensed into liquid and then flow into the collector, preventing the liquid fatty acids from flowing back to the distillation kettle 1.

[0041] 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 7. 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 7. The liquid fatty acids have a high gravitational potential energy when falling, resulting in a large impact force on the collection tray 7. This easily causes the liquid fatty acids to scatter 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 and the upper condenser tube 42 correspond one-to-one, and the upper opening of the gas guide pipe 73 is provided with multiple circumferentially spaced... 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.

[0042] 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, so that the high-temperature mixed steam can quickly rise and pass through the liquid collection plate 7.

[0043] Furthermore, to prevent the liquid fatty acids falling into the collection pan 7 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.

[0044] Furthermore, the cone-shaped and inverted cone-shaped bodies can be either conical or pyramidal structures. And to ensure the lightweight and low-cost operation of the liquid collection tray 7, the cone-shaped and inverted cone-shaped bodies are closed hollow structures.

[0045] Furthermore, to ensure the receiving effect of the liquid collection tray 7, the liquid collection tray 7 includes a base and a retaining part 7a integrally formed 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.

[0046] 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.

[0047] 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 be stuck 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 7.

[0048] 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 5-8 As shown, a 500mm high installation space is left between every two adjacent vertically aligned condenser tubes 42. A liquid-separating device for blocking liquid is installed within this space. This liquid-separating device is equivalent to a liquid-separating module 6. The liquid-separating module 6 includes an annular clamp and multiple vertically arranged, closely spaced corrugated liquid-separating elements 61 within the annular clamp. Between two adjacent corrugated liquid-separating elements 61, there is a corrugated groove 63 extending in a wavy shape. These multiple corrugated grooves 63 form a group of corrugated grooves that allow high-temperature mixed vapor to pass upwards. The corrugated liquid-separating elements 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 entrained liquid fatty acids into the condenser tube of the upper shell-and-tube condenser after rising, and avoids the condensation of fatty acid monomers with higher condensation temperatures in the condenser tube of the previous shell-and-tube condenser with a lower condensation temperature, ensuring the smooth progress of the fatty acid production process.

[0049] Furthermore, multiple corrugated liquid-blocking components 61 constitute a corrugated liquid-blocking component group, and multiple corrugated liquid-blocking component groups arranged vertically are provided inside the annular clamp; to ensure the liquid-blocking effect, in this embodiment, two layers of corrugated liquid-blocking component groups are provided inside the annular clamp; as... Figure 8 As shown, if two adjacent wave groove groups are aligned with each other, the multiple wave liquid separators 61 can only form a single barrier for the droplets in the high-temperature steam. Therefore, in order to provide a barrier effect, in this embodiment, each pair of adjacent wave 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.

[0050] Furthermore, to facilitate the installation of multiple corrugated liquid-blocking components 61, the annular clamp includes multiple interlocking annular sub-clamps 62. Each annular sub-clamp 62 contains a corresponding liquid-blocking module 6. 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-blocking modules 6 to adapt to different processing conditions. For example, if the mixture in the distillation vessel contains a large amount of solids and the mixed gas needs to rise at a slower speed, the heating temperature of the distillation vessel 1 can be reduced to allow the mixed vapor to rise at a slower speed. Under these production conditions, the corresponding annular sub-clamp 62 can be rotated by a smaller angle to ensure the gas rising speed while blocking the liquid. If the mixture in the distillation vessel contains less solids and the mixed gas needs to rise at a faster speed... The heating temperature of the distillation vessel 1 can be increased by raising the temperature, causing the mixed vapor to rise at a slower rate. Under these production conditions, the corresponding annular clamp 62 can be rotated at a larger angle to prevent the rapidly rising gas from carrying droplets upward into the shell-and-tube condenser 42. Specifically, one end of the annular clamp 62 is provided with a flange ring 621, and multiple positioning holes 622 are evenly distributed along the circumference of the flange ring 621. The flange rings 621 of every two adjacent annular clamps 62 are connected to each other. After the corresponding annular clamp 62 is rotated to the predetermined position, the positioning holes 622 of the two adjacent flange rings 621 are aligned one by one and locked with screws. For easy 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.

[0051] Furthermore, the corrugated liquid-blocking component 61 includes multiple equally spaced bent sections, with a vertical unit perforated plate 611 formed between every two adjacent bent sections. The included angle between every two unit perforated plates 611 is 60°. To save installation space, the vertical height of the unit perforated plate 611 ranges from 45mm to 60mm. In this embodiment, the corrugated liquid-blocking component 61 is a corrugated wire mesh formed by multiple interlaced stainless steel wires. The diameter of the stainless steel wires ranges from 1.2mm to 1.8mm to form as fine a liquid-blocking perforation as possible, ensuring the liquid-blocking effect.

[0052] Furthermore, to ensure that high-temperature steam can pass through while effectively blocking liquid droplets, the mesh size of the liquid-blocking holes on the corrugated liquid-blocking component 61 in this embodiment is in the range of 110-125. The mesh size is the number of liquid-blocking holes per square centimeter in the corrugated liquid-blocking component 61. When gas carrying liquid droplets passes through the corrugated liquid-blocking component within this mesh size range, the sufficiently fine multiple liquid-blocking holes can form a sufficient contact area with the gas, achieving the best liquid-blocking effect.

[0053] 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.

[0054] 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.

[0055] Example 2: The difference between this example and the above examples is that the structure of the wave-shaped liquid barrier is different. In this example, the wave-shaped liquid barrier 61 is a wave plate with a plurality of liquid barrier through holes. The liquid barrier through holes can be pre-formed on the wave plate or drilled out from the whole wave plate. The liquid barrier through holes on the wave plate can also achieve the same liquid barrier effect as in the above examples.

[0056] Furthermore, the corrugated plate has multiple rows of spaced liquid-blocking through holes; due to the upward flow of the high-temperature mixed gas, in order to enhance the blocking effect on fatty acid droplets and prevent any leaked droplets from entering the upper condenser tube 42 under the action of vapor, the arrangement of the multiple liquid-blocking through holes in this embodiment is rather special. Specifically, as shown in... Figure 6 As shown, from bottom to top, the diameter of multiple liquid-blocking holes gradually decreases, and the distance between two adjacent liquid-blocking holes in the same row also gradually decreases; as the gas carrying fatty acid droplets flows upward, the wave-shaped liquid-blocking device has a better effect on blocking the droplets, preventing any leaked fatty acid droplets from entering the condenser tube at the top.

[0057] 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.
