DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment 1

[0033] As Figure 1 - Figure 10As shown, the present application discloses a kind of refining tower for octyl glycerin production, including fixed tower body 1, sliding tower body 2 is slidably arranged at the top of fixed tower body 1, sliding tower body 2 controls the vacuum degree inside fixed tower body 1 by controlling the distance between fixed tower body 1, it needs to be explained, when octyl glycerin raw material is carried out deodorization operation, the vacuum degree generally required is between 0.1 and 0.5 bar, so when using the deodorization kettle to carry out the deodorization treatment of octyl glycerin raw material, the vacuum degree inside fixed tower body 1 is controlled between 0.1 and 0.5 bar, since sliding tower body 2 is slidably arranged at the top of fixed tower body 1, when sliding tower body 2 is slid upward at the top of fixed tower body 1, the total space inside fixed tower body 1 and sliding tower body 2 will increase, so the vacuum degree inside fixed tower body 1 will decrease, when sliding tower body 2 is slid downward at the top of fixed tower body 1, the total space inside fixed tower body 1 and sliding tower body 2 will decrease, so the vacuum degree inside fixed tower body 1 will increase, therefore, the vacuum degree inside fixed tower body 1 can be controlled by controlling the distance between fixed tower body 1 and sliding tower body 2, top tower body 3 is arranged at the top of sliding tower body 2, bottom tower body 4 is arranged at the bottom of fixed tower body 1, feed mechanism 5 is arranged on the top surface of top tower body 3, feed mechanism 5 is used to inject octyl glycerin raw material into the inside of fixed tower body 1, steam inlet mechanism 6 is arranged on one side of fixed tower body 1, steam inlet mechanism 6 is used to pass steam into the inside of fixed tower body 1, vacuum pump 7 is arranged at the top of top tower body 3, vacuum pump 7 is used to suck the gas inside top tower body 3, so that negative pressure is formed in the inside of top tower body 3, discharge pipeline 8 is arranged at the bottom of bottom tower body 4.

[0034] It needs to be explained that fixed tower body 1, sliding tower body 2 and top tower body 3 together constitute a sealed deodorization kettle, when using, octyl glycerin raw material can be injected into the inside of fixed tower body 1 through feed mechanism 5, so that octyl glycerin raw material enters the inside of fixed tower body 1, the temperature of octyl glycerin raw material during deodorization is generally controlled between 150 degrees Celsius and 200 degrees Celsius, so it is necessary to install electric heater on the side wall of fixed tower body 1, sliding tower body 2 and top tower body 3, so that the temperature inside the sealed deodorization kettle can be between 150 degrees Celsius and 200 degrees Celsius, the specific temperature inside the deodorization kettle is adaptively selected by the person skilled in the art according to the specification of octyl glycerin raw material and the flow of octyl glycerin raw material during deodorization, to ensure that octyl glycerin raw material can complete deodorization treatment when passing through discharge pipeline 8.

[0035] In addition, it needs to be noted that a vacuum gauge is installed in fixed tower body 1, the vacuum gauge is used to collect the vacuum degree inside fixed tower body 1, the installation position and installation quantity of vacuum gauge can be adaptively selected by the person skilled in the art according to the specification of fixed tower body 1, to ensure that the vacuum degree collected by vacuum gauge inside fixed tower body 1 is accurate.

[0036] When the octyl decanoic acid glyceride raw material enters the inside of the fixed tower body 1 through the feeding mechanism 5, the octyl decanoic acid glyceride raw material will form multiple streams and droplets in the inside of the fixed tower body 1, which can not only ensure that the fixed tower body 1 can quickly heat the octyl decanoic acid glyceride raw material to 150-200 degrees Celsius, but also promote the volatilization of impurities in the octyl decanoic acid glyceride raw material, greatly improving the efficiency of the octyl decanoic acid glyceride raw material deodorization.

[0037] During the deodorization of the octyl decanoic acid glyceride raw material, the vacuum degree inside the fixed tower body 1 is collected in real time by the vacuum gauge. A person skilled in the art can select a preset value between 0.1 bar and 0.5 bar, for example, 0.3 bar. When the vacuum degree inside the fixed tower body 1 collected in real time by the vacuum gauge is greater than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too large. At this time, the sliding tower body 2 can be controlled to slide upward at the top of the fixed tower body 1, and the total space inside the fixed tower body 1 and the sliding tower body 2 will increase, so that the vacuum degree inside the fixed tower body 1 will decrease, and the vacuum degree inside the fixed tower body 1 will drop to 0.3 bar. When the vacuum degree inside the fixed tower body 1 collected in real time by the vacuum gauge is less than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too small. At this time, the sliding tower body 2 can be controlled to slide downward at the top of the fixed tower body 1, and the total space inside the fixed tower body 1 and the sliding tower body 2 will decrease, so that the vacuum degree inside the fixed tower body 1 will increase, and the vacuum degree inside the fixed tower body 1 will rise to 0.3 bar. The vacuum degree inside the fixed tower body 1 is always within a stable range, ensuring the stability of the deodorization of the octyl decanoic acid glyceride raw material.

[0038] In addition, the vacuum degree inside the fixed tower body 1 is adjusted by the distance between the fixed tower body 1 and the sliding tower body 2, without controlling the power of the vacuum pump 7. In this way, the vacuum pump 7 can always be at a constant working frequency, ensuring the stability of the vacuum pump 7. At the same time, the vacuum degree inside the fixed tower body 1 is adjusted by the fixed tower body 1 and the sliding tower body 2, which is fast, efficient, and will not affect the efficiency of the vacuum pump 7 in discharging volatile impurities, greatly improving the effect of the deodorization of the octyl decanoic acid glyceride raw material. Moreover, the deodorization kettle can continuously process the octyl decanoic acid glyceride raw material, that is, the octyl decanoic acid glyceride raw material can be continuously added to the deodorization kettle through the feeding mechanism 5, and the deodorization kettle can continuously and efficiently deodorize the incoming octyl decanoic acid glyceride raw material, simplifying the deodorization operation of the octyl decanoic acid glyceride raw material.

[0042] In use, when the vacuum gauge collects the vacuum degree inside the fixed tower body 1 in real time greater than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too large, at this time the microprocessor can open the hydraulic cylinders 12, so that the hydraulic cylinders 12 drive the sliding tower body 2 upward through the hydraulic rods 22, control the sliding tower body 2 to slide upward on the top of the fixed tower body 1, the total space inside the fixed tower body 1 and the sliding tower body 2 will increase, so that the vacuum degree inside the fixed tower body 1 will decrease, so that the vacuum degree inside the fixed tower body 1 decreases to 0.3 bar, when the vacuum gauge collects the vacuum degree inside the fixed tower body 1 in real time less than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too small, at this time the microprocessor can open the hydraulic cylinders 12, so that the hydraulic cylinders 12 drive the sliding tower body 2 downward through the hydraulic rods 22, control the sliding tower body 2 to slide downward on the top of the fixed tower body 1, the total space inside the fixed tower body 1 and the sliding tower body 2 will decrease, so that the vacuum degree inside the fixed tower body 1 will increase, so that the vacuum degree inside the fixed tower body 1 rises to 0.3 bar, so that the vacuum degree inside the fixed tower body 1 is always in a stable range, ensuring the stability of the capric caprylic acid glyceride raw material deodorization.

[0043] Example 3

[0044] As Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the deodorization mechanism 21 comprises a bottom ring 211, the top surface of the bottom ring 211 is fixedly connected with a connecting rod 212, the top end of the connecting rod 212 is fixedly connected with a liquid collecting disc 213, the inside of the liquid collecting disc 213 is provided with a plurality of deodorization cylinders 215, and it should be noted that when the capric acid glyceride raw material is received by the liquid collecting disc 213, the capric acid glyceride raw material will be flat on the top surface of the liquid collecting disc 213 because the capric acid glyceride raw material will flow, and because the vacuum pump 7 sucks gas at the top of the top tower body 3, and the steam inlet mechanism 6 introduces steam from the bottom of the side of the fixed tower body 1, the steam will flow upwards at the deodorization cylinder 215, and the rapidly flowing steam will form an air wall, hindering the flow of the capric acid glyceride raw material, so that the capric acid glyceride raw material is just at the edge position of the deodorization cylinder 215.

[0045] As shown in Figure 6 and Figure 7 As shown, the deodorization cylinder 215 comprises a cylinder body 2151, the top end of the cylinder body 2151 is fixedly connected with a cylinder head 2152, the inside of the cylinder body 2151 is provided with a cylinder groove 2153, the side wall of the cylinder groove 2153 is provided with a plurality of parallelly arranged liquid flow grooves 2154, the bottom surface of the cylinder body 2151 is fixedly connected with a plurality of liquid drop heads 2155, the positions of the liquid drop heads 2155 correspond to the positions of the liquid flow grooves 2154 one by one, and it should be noted that the steam will flow upwards in the cylinder groove 2153, so that the capric acid glyceride raw material is just at the edge position of the cylinder groove 2153, and because the side wall of the cylinder groove 2153 is provided with a plurality of parallelly arranged liquid flow grooves 2154, the capric acid glyceride raw material at the edge position of the cylinder groove 2153 will flow downwards along the liquid flow grooves 2154 under the action of gravity, and in the process of flowing, the capric acid glyceride raw material will continuously volatilize impurities due to high temperature and negative pressure, and the volatilized impurities will also quickly separate from the capric acid glyceride raw material under the action of the rapidly flowing steam, thereby greatly improving the deodorization effect of the capric acid glyceride raw material, and those skilled in the art can set the length of the cylinder body 2151 according to the flowing speed of the capric acid glyceride raw material in the liquid flow grooves 2154, so that the capric acid glyceride raw material can achieve sufficient deodorization time.

[0046] The side surface of the bottom ring 211 is fixedly connected with a fixed block 214, the fixed block 214 is fixedly connected with the inner wall of the fixed tower body 1, and the diameter of the liquid collecting disc 213 is equal to the inner diameter of the sliding tower body 2, so that when the sliding tower body 2 slides up and down, the deodorization mechanism 21 is not affected, that is, the position of the deodorization mechanism 21 is always fixed, thereby ensuring the stability of the deodorization of the capric acid glyceride raw material.

[0047] In addition, it should be noted that due to the surface tension of capric caprylic acid glyceride raw material itself and the influence of the upward rapid flow of steam, the downward flow speed of capric caprylic acid glyceride raw material is also related to the size of the flow tank 2154, which is set by the person skilled in the art according to the overall specifications of the fixed tower body 1 to ensure that the capric caprylic acid glyceride raw material reaches sufficient deodorization time.

[0048] When the capric caprylic acid glyceride raw material flows to the bottom end in the flow tank 2154, it will form droplets along the droplet head 2155, and the capric caprylic acid glyceride raw material forming droplets will greatly increase the specific surface area, thereby greatly improving the volatilization efficiency of impurities in the capric caprylic acid glyceride raw material, and indirectly improving the deodorization efficiency of the capric caprylic acid glyceride raw material.

[0049] Example 4

[0050] As shown in Figure 8 The bottom tower body 4 includes a bottom body 41, and the inside of the bottom body 41 is provided with a collection cavity 43. The bottom surface center of the collection cavity 43 is provided with an external port 44. The top surface of the bottom body 41 is fixedly connected with a third flange 45. It should be noted that the inner side of the discharge pipeline 8 is connected with the external port 44. The third flange 45 is matched with the first flange 13, and the third flange 45 and the first flange 13 are sealingly connected by bolts. The bottom of the bottom body 41 is fixedly connected with a support leg 42, which supports the bottom body 41. In addition, it should be noted that the bottom of the collection cavity 43 is arc-shaped, so that the capric caprylic acid glyceride dropped on the bottom of the collection cavity 43 can enter the discharge pipeline 8 through the external port 44, realizing the collection of capric caprylic acid glyceride.

[0051] Example 5

[0052] As shown in Figure 9As shown, the feeding mechanism 5 includes a feeding pipe 51, with a disc 52 fixedly connected to the bottom end of the feeding pipe 51. A drain pipe 53 is fixedly connected to the bottom surface of the disc 52. There is a gap between the disc 52 and the top tower 3. It should be noted that the feeding pipe 51 includes two sections, one of which is a retractable movable pipe. This movable pipe is fixedly connected to the top end of the disc 52 and slidably connected to the top surface of the top tower 3. When the top tower 3 moves up and down in the sliding tower 2, the top surface of the top tower 3 can slide on the side of the movable pipe to ensure that the up-and-down movement of the top tower 3 does not affect the position of the disc 52. A solenoid valve is installed inside the feeding pipe 51, which is controlled by the control panel on the fixed tower 1. The feeding pipe 51 and... The external caprylic / capric glyceride raw material tank is connected, and the caprylic / capric glyceride raw material tank can directly inject caprylic / capric glyceride raw material into the feed pipe 51. The flow rate of caprylic / capric glyceride raw material in the feed pipe 51 is controlled by the solenoid valve inside the feed pipe 51. Since the inside of the fixed tower body 1 is a negative pressure environment, the caprylic / capric glyceride raw material in the feed pipe 51 can automatically enter the disc body 52 under the external atmospheric pressure. The bottom surface of the disc body 52 is fixedly connected to multiple drain pipes 53, which are evenly distributed. The multiple drain pipes 53 are staggered from the deodorization cylinder 215 on the top surface of the liquid collection tray 213. In this way, when the drain pipes 53 deliver caprylic / capric glyceride raw material to the liquid collection tray 213, it can prevent the caprylic / capric glyceride raw material from directly entering the deodorization cylinder 215.

[0053] Example 6

[0054] like Figure 10 As shown, the vacuum pump 7 includes a pump body 71. One end of the pump body 71 is fixedly connected to an inlet pipe 73, and the other end is fixedly connected to a drive motor 72. A single screw 74 is installed inside the pump body 71. The output end of the drive motor 72 is connected to the single screw 74 via a coupling. An outlet pipe 75 is fixedly connected to the top of the pump body 71. It should be noted that the end of the inlet pipe 73 furthest from the pump body 71 is connected to the top surface of the top tower 3 via a telescopic pipe. During operation, when the drive motor 72 is turned on, the output shaft of the drive motor 72 drives the single screw 74 via the coupling. The high-speed rotating single screw 74 can displace the inlet pipe... The gas in 73 is transported to the outlet pipe 75 through the pump body 71 and finally output through the outlet pipe 75. Since there is a gap between the disc body 52 and the top tower body 3, the gas flow direction in the fixed tower body 1 is: steam is input into the interior of the fixed tower body 1 by the steam inlet mechanism 6. The steam inlet mechanism 6 is essentially an inlet pipe. The end of the inlet pipe away from the fixed tower body 1 is connected to the steam generator to ensure that the steam can be transported to the interior of the fixed tower body 1 through the inlet pipe. The steam inside the fixed tower body 1 is transported to the top tower body 3 by the deodorization cylinder 215 and finally output by the vacuum pump 7 to maintain the negative pressure environment inside the fixed tower body 1.

[0055] The above has been described in detail one embodiment of the present application, but the content is only the preferred embodiment of the present application, cannot be considered for limiting the scope of the present application. Any equivalent changes and improvements made in the scope of the present application, should still belong to the scope of the present application.
