[0002] Esterification is a type of organic chemical reaction, mainly the reaction between alcohol and carboxylic acid or inorganic oxygen-containing acid to produce ester and water. It is divided into three categories: the reaction between carboxylic acid and alcohol, the reaction between inorganic oxygen-containing acid and alcohol, and the reaction between inorganic strong acid and alcohol. Concentrated sulfuric acid is often used as a catalyst. The reaction between polycarboxylic acid and alcohol can produce a variety of esters. The reaction between inorganic strong acid and alcohol is generally faster and will produce a large amount of water vapor and heat. Usually, the reaction uses a reactor as the reaction vessel.

After entering the circulating cooling chamber, the cold water will continuously accumulate and overflow in the space formed by the staggered arrangement of a plurality of first baffles and a plurality of second baffles, so that the cold water is always in the state of flowing water, so as to achieve the cooling and condensation measures for the high-temperature steam in the circulating cooling chamber.

[0019] Embodiment 1 This embodiment is intended to promote the solution of the problem that a large amount of heat and hot water vapor will be generated during the esterification process. These water vapors contain a certain amount of esterification products. If these products are directly discharged to the outside, they will cause certain health hazards to the surrounding workers and cause waste of esterification products, which does not meet the actual production safety needs.

A condensate delivery pipe 304 is fixedly connected to the inner wall of the condensate delivery pipe 304. A condensate collection bottle 305 is fixedly connected to the other end of the condensate delivery pipe 304. A plurality of heat conducting pipes 8 are provided, a circulating cooling chamber 301 is formed between the first sealing baffle plate 9 and the inner wall of the fixed frame 3, and a plurality of first baffle plates 6 and a plurality of second baffle plates 7 are fixedly connected to the inner wall of the circulating cooling chamber 301; The inner wall of the circulating cooling chamber 301 is fixedly connected with a water outlet pipe 5 , which is communicated with the interior of the circulating cooling chamber 301 . A plurality of first baffles 6 and a plurality of second baffles 7 are evenly and staggeredly arranged.

[0020] In this embodiment: first, the alcohol and inorganic strong acid required for the reaction are added into the esterification reactor body 1 through the feed pipe 102 connected to the outer wall of the reactor sealing upper cover plate 101 fixed to the outer wall of the esterification reactor body 1 to react. The high-temperature water vapor generated in the reaction process will be transported to the condensation chamber 302 in the fixed frame 3 through the first air outlet pipe inlet 103 connected to the outer wall of the reactor sealing upper cover plate 101. At this time, cold water is introduced into the circulating cooling chamber 301 in the fixed frame 3 through the cold water delivery pipe 4 connected to the outer wall of the fixed frame 3. After entering the circulating cooling chamber 301, the cold water will be arranged in a staggered manner between a plurality of first baffles 6 and a plurality of second baffles 7. The space formed is continuously filled and overflowed, so that the cold water is always in the state of flowing water, and one side of several heat pipes 8 is in the condensation chamber 302 and in contact with high-temperature water vapor, while the other end of the heat pipe 8 is subjected to heat conduction by the flowing water in the circulating cooling chamber 301, and the heat on one side in the condensation chamber 302 is conducted to the circulating cooling chamber 301 and part of it is conducted away by the flowing water for cooling, thereby achieving the cooling and condensation measures for the high-temperature steam in the circulating cooling chamber 301, and the condensed cold water and esterification products are transported to the condensate delivery pipe 304 with the air flow, and are transported to the condensate collection bottle 305 with the condensate delivery pipe 304 for storage.

[0021] Embodiment 2 This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 7 The outer wall of the condensate collecting bottle 305 is fixedly connected with a reaction delivery tube 11 , and the other end of the reaction delivery tube 11 is connected to the inside of the condensation chamber 302 .

[0022] In this embodiment: the cold water in the condensate collection bottle 305 will pass through the filter 306 into the reaction delivery pipe 11 and be transported to the condensation chamber 302, and will be recycled to cool the hot steam transported in the condensation chamber 302, thereby increasing the condensation efficiency in the condensation chamber 302, and the esterification product will be filtered by the filter 306 and retained in the condensate collection bottle 305 for easy unified collection and removal.

[0023] Embodiment 3 This embodiment is intended to promote the solution of the problem that the intensity of the reaction in the esterification reactor body is determined by the amount of added alcohol and excess inorganic strong acid, and the intensity of the reaction directly affects the amount of high-temperature steam generated. When a small amount of alcohol is reacted in the esterification reactor body, the amount of steam generated will be small. At this time, when the steam is passed into the condensation chamber, the heat energy in the hot steam is not diffused in a concentrated manner due to the large space in the condensation chamber, which reduces the condensation rate and does not meet the actual processing needs. This embodiment is an improvement made on the basis of Example 2. For details, please refer to Figure 1-Figure 7, the outer walls of the plurality of heat conducting pipes 8 are embedded in the interior of the plurality of first baffles 6 and the plurality of second baffles 7, the outer wall of the first sealing baffle plate 9 is fixedly connected with a second return spring 901, and the other end of the second return spring 901 is fixedly connected with the outer wall of the first baffle 6; The outer wall of the second sealing baffle plate 10 is fixedly connected with a third return spring 1001, and the other end of the third return spring 1001 is fixedly connected with the inner wall of the fixed frame 3, and the inner wall of the fixed frame 3 is provided with a sliding guide groove 303; The outer walls of the first sealing baffle plate 9 and the second sealing baffle plate 10 are both sleeved and connected with a sealing block 902 , and the outer wall of the sealing block 902 is slidably connected to the inner wall of the sliding guide groove 303 .

[0024] In this embodiment: Since the intensity of the reaction in the esterification reaction kettle body 1 is determined by the amount of added alcohol and excess inorganic strong acid, the intensity of the reaction directly affects the amount of high-temperature steam generated. When a small amount of alcohol is reacted in the esterification reaction kettle body 1, the amount of steam generated will be small. At this time, when the steam is passed into the condensation chamber 302, the heat energy in the hot steam is not diffused in a concentrated manner due to the large space in the condensation chamber 302, which reduces the condensation rate and does not meet the actual processing needs; Therefore, when the reaction amount in the esterification reactor body 1 is small, the pressure of the steam transported to the condensation chamber 302 will also decrease accordingly. At this time, the pressure in the condensation chamber 302 is not enough to squeeze the first sealing baffle plate 9 and the second sealing baffle plate 10 to both sides to cause the corresponding second return spring 901 and the third return spring 1001 to be compressed and displaced. At this time, the first sealing baffle plate 9 and the second sealing baffle plate 10 will slide toward each other along the sliding guide groove 303 through the corresponding sealing block 902 under the rebound action of the corresponding second return spring 901 and the third return spring 1001. Since the condensation chamber 302 is formed by the spacing space between the first sealing baffle plate 9 and the second sealing baffle plate 10, this operation is equivalent to reducing the overall space size of the condensation chamber 302. Therefore, after the steam is introduced, the normal condensation rate can still be carried out in the small space condensation chamber 302. On the contrary, when the reaction amount in the esterification reactor body 1 is large, the pressure of the steam transported to the condensation chamber 302 will also increase accordingly. If the exposed part of the heat pipe 8 in the condensation chamber 302 is too short, the insufficient heat exchange area of ​​the heat conduction of the heat pipe 8 will also affect the condensation speed. Due to the introduction of a large amount of high-temperature steam, the pressure in the condensation chamber 302 is sufficient to squeeze the first sealing barrier plate 9 and the second sealing barrier plate 10 to both sides, causing the corresponding second return spring 901 and the third return spring 1001 to be compressed and displaced. At this time, as the sealing blocks 902 corresponding to the first sealing barrier plate 9 and the second sealing barrier plate 10 slide along the sliding guide groove 303, the area of ​​the heat pipe 8 exposed in the condensation chamber 302 increases, that is, the heat exchange area of ​​the heat pipe 8 increases, further increasing the condensation efficiency.

[0025] Embodiment 4 This embodiment is intended to promote the solution of the problem that the size of the condensation chamber 302 in the embodiment 3 changes with the amount of steam introduced. When the space in the condensation chamber 302 becomes smaller, the sealing obstruction of the first sealing baffle plate 9 and the second sealing baffle plate 10 will prevent the steam in the second outlet pipe access valve 2 from being transported into the condensation chamber 302, resulting in condensation failure. This embodiment is an improvement made on the basis of the embodiment 3. For details, please refer to Figure 1-Figure 7 The outer wall of the reactor sealing upper cover plate 101 is provided with a first gas outlet pipe access port 103, the inner wall of the first gas outlet pipe access port 103 is rotatably connected to the end of the gas outlet pipe 104, the other end of the gas outlet pipe 104 is fixedly connected to a limit block 105, a filter 306 is installed at the end of the condensate collection bottle 305, and the output end of the filter 306 is fixedly connected to the end of the reaction delivery pipe 11; There are two limit blocks 105, which are axially symmetrically arranged. There are a plurality of second air outlet pipe access valves 2, which are arranged in a circumferential direction. The outer walls of the plurality of second air outlet pipe access valves 2 are all provided with first card slots 201, the inner contour of the first card slots 201 matches the outer contour of the limit card block 105, and the inner wall of the first card slots 201 is provided with second card slots 202; The cross section of the second clamping groove 202 is set as an annular groove. The inner wall of the second clamping groove 202 is fixedly connected with the first return spring 203 . The other end of the first return spring 203 is tightly fitted with the outer wall of the limiting clamping block 105 .

[0026] In this embodiment: Therefore, it is necessary to adjust the outlet pipe 104 to be connected to the second outlet pipe access valve 2 at different positions according to the size of the reaction amount in the esterification reaction kettle main body 1. When the total amount of reaction in the esterification reaction kettle main body 1 is small, the outlet pipe 104 is rotated by rotating the end of the first outlet pipe access port 103 connected to make the end of the outlet pipe 104 connected to the rightmost second outlet pipe access valve 2 arranged in a circle. When the total amount of reaction in the esterification reaction kettle main body 1 is large, the outlet pipe 104 is passed into the leftmost second outlet pipe access valve 2 arranged in a circle. 2, the access method is to rotate the air outlet pipe 104 to the corresponding second air outlet pipe access valve 2, press the air outlet pipe 104 downward to make the end with the limiting block 105 enter the first slot 201 opened by the corresponding second air outlet pipe access valve 2, when the limiting block 105 fully enters the first slot 201, continue to press the air outlet pipe 104 downward to make the limiting block 105 squeeze the first return spring 203 and enter the second slot 202, then rotate the second air outlet pipe access valve 2 to make the position of the limiting block 105 engage with the second slot 202, so as to limit the position of the air outlet pipe 104.

[0027] Embodiment 5 This embodiment is intended to promote the solution of the problem that the water and esterification products generated during condensation in the condensation chamber 302 are easily attached to the surface of the heat pipe 8 in the condensation chamber 302 area, which affects the subsequent use in a timely manner. This embodiment is an improvement made on the basis of embodiments 1-4. For details, please refer to Figure 8-Figure 13 A plurality of first fixing plates 81 are fixed to the outer wall of the second sealing blocking plate 10, a fixing tube 82 is fixed to the outer wall of the first fixing plate 81, a first horizontal shaft 84 is rotatably provided on the inner wall of the fixing tube 82, a spring 83 is fixedly sleeved on the outer wall of the first horizontal shaft 84, a take-up drum 85 is fixed to the outer wall of the first horizontal shaft 84, a connecting steel rope 86 is sleeved on the outer wall of the take-up drum 85, one end of the connecting steel rope 86 is fixed to the outer wall of the first sealing blocking plate 9, a worm 87 is fixed to one end of the first horizontal shaft 84, a worm wheel 88 is meshed with the outer wall of the worm 87, and the worm wheel 88 is rotatably provided on the outer wall of the second sealing blocking plate 10; The worm gear 88 is sleeved on the outer wall of the heat conducting pipe 8, and a second fixing plate 90 is also fixed to the outer wall of the second sealing baffle plate 10. A second horizontal shaft 92 is rotatably provided on the outer wall of the second fixing plate 90. A torsion spring 91 is sleeved on the outer wall of the second horizontal shaft 92. One end of the torsion spring 91 is fixed to the outer wall of the second fixing plate 90, and a rotating wheel 93 is fixed to the other end of the torsion spring 91. One end of the second horizontal shaft 92 is fixed to the outer wall of the rotating wheel 93. A plurality of cleaning brushes 89 are fixed to the inner walls of the rotating wheel 93 and the worm wheel 88; A circular through groove 96 is formed on the second sealing baffle plate 10 , a first protrusion 94 is fixed to the outer wall of the worm wheel 88 , and a plurality of second protrusions 95 are fixed to the outer wall of the rotating wheel 93 . The ends of the first protrusion 94 and the second protrusion 95 are both configured as hemispherical surfaces.

[0028] In this embodiment, in order to avoid the above situation, during the process of transporting steam into the condensation chamber 302, when the air pressure in the condensation chamber 302 increases, the second sealing baffle plate 10 will slide along the inner wall of the sliding guide groove 303. The sliding of the second sealing baffle plate 10 will increase the space in the condensation chamber 302. During the sliding process of the second sealing baffle plate 10, the second sealing baffle plate 10 gradually moves away from the first sealing baffle plate 9. The connecting steel rope 86 connected to the outer wall of the first sealing baffle plate 9 is continuously pulled, causing the connecting steel rope 86 to be continuously pulled out from the winding reel 85. At this time, the winding reel 85 is pulled along with the connecting steel rope 86. The wire take-up drum 85 rotates synchronously with the first horizontal axis 84 when the first horizontal axis 84 rotates. When the first horizontal axis 84 rotates, the spring 83 on the outer wall is continuously twisted and stored in the fixed tube 82. The rotation of the wire take-up drum 85 also rotates synchronously with the worm 87. The rotation of the worm 87 rotates synchronously with the worm wheel 88 through the meshing relationship. When the worm wheel 88 rotates, the cleaning brush 89 on the inner wall rotates to clean the condensed water droplets and esterification products on the outer wall of the heat pipe 8, so that they are swept away by the cleaning brush 89. The movement of the second sealing baffle plate 10 also drives the worm wheel 88 and the cleaning brush 89 to continuously move along the outer wall of the heat pipe 8, further cleaning the heat pipe 8 evenly. When the worm gear 88 rotates, the first protrusion 94 on the outer wall of the worm gear 88 moves in a circle following the rotation of the worm gear 88, and the first protrusion 94 continuously contacts the second protrusion 95 through the circular through groove 96. Since the ends of the first protrusion 94 and the second protrusion 95 are both set to be hemispherical, the contact will cause the second protrusion 95 to bear force on the rotating wheel 93. After the rotating wheel 93 is subjected to force, the second horizontal axis 92 is caused to rotate. The second horizontal axis 92 rotates along the outer wall of the second fixed plate 90, and the torsion spring 91 is twisted during rotation to facilitate subsequent resetting. When the rotating wheel 93 follows the second horizontal axis 92 to tilt and rotate to a certain extent, the cleaning brush 89 on the inner wall of the rotating wheel 93 will follow the synchronous rotation and tilt, and the tilting will change the contact distance and pressing force of the cleaning brush 89 corresponding to the outer wall of the heat conducting pipe 8 that is in contact at this time, and as the worm gear 88 rotates, the cleaning brush 89 on the inner wall of the rotating wheel 93 will rotate to a certain extent. 8 continues to move in a circle with the first protrusion 94. When the first protrusion 94 is out of contact with the second protrusion 95, the torsion spring 91 is reset to torsionally drive the rotating wheel 93 to rotate and reset from the tilted state. At this time, the contact distance and pressure strength of the outer wall of the heat-conducting tube 8 that the cleaning brush 89 contacts at this time are changed. Therefore, during the cleaning process of the surface of the heat-conducting tube 8, the contact distance and pressure strength of the outer wall of the heat-conducting tube 8 that the cleaning brush 89 contacts at this time are constantly changed to achieve a better cleaning effect. The rotation of the rotating wheel 93 to a certain extent prompts the cleaning brush 89 on the inner wall of the rotating wheel 93 to sweep and clean the surface of the heat-conducting tube 8 at another angle, so as to clean the surface of the heat-conducting tube 8 more evenly, so that the condensed water mixed with the esterification product drips from the outer wall of the heat-conducting tube 8. When steam is no longer introduced into the condensation chamber 302, the air pressure in the condensation chamber 302 decreases, and the second reset spring 901 rebounds and slides the second sealing baffle plate 10 along the inner wall of the sliding guide groove 303 to reset. The twisted and tightened mainspring 83 is continuously twisted and restored as the second sealing baffle plate 10 resets. The twisting recovery of the mainspring 83 causes the first transverse axis 84 of the inner wall to rotate, and the rotation of the first transverse axis 84 causes the take-up drum 85 to rotate synchronously. The rotation of the take-up drum 85 will gradually reel the connecting steel rope 86 onto the outer wall, and the rotation of the take-up drum 85 will also cause the worm 87 to rotate. The worm 87 now reversely meshes with the worm wheel 88, and the worm wheel 88 reversely rotates to clean the surface of the heat pipe 8.
