Description

Technical Field

[0001] The invention relates to the technical field of sampler cooling, in particular to a jacket cooling sampler. Background Art

[0002] MIBK, methyl isobutyl ketone, also known as 4-methyl-2-pentanone, is a vital organic compound. As a multifunctional organic solvent and chemical intermediate, it plays an indispensable role in many industrial fields such as coatings, inks, resins, adhesives, medicines, pesticides and dyes.

[0003] There are various production processes for MIBK, including the isopropanol method, the acetone method and the emerging biosynthesis method. Regardless of the production process, various impurities will inevitably be produced during the reaction. Therefore, in order to obtain high-purity MIBK products, it is usually necessary to use efficient separation technologies such as distillation for purification.

[0004] Specifically, in the production process, the MIBK discharged from the bottom of the MIBK dehydration tower is first sent to the distillation tower for further purification. The working principle of the distillation tower is to effectively separate MIBK from other high-boiling impurities by utilizing the difference in boiling points of different components. During the distillation process, a relatively pure MIBK product is collected at the top of the tower, while the residual liquid containing high-boiling impurities is discharged at the bottom of the tower.

[0005] In order to ensure product quality, samplers are usually installed at the top and bottom of the distillation tower to monitor the quality of the produced MIBK in real time. However, it is worth noting that since the residual liquid containing high-boiling impurities is discharged from the bottom of the tower, its temperature is relatively high, so there are certain safety risks in the sampling process, which may cause accidental injuries such as burns to the staff.

[0006] Based on this, it is urgent to develop a sampler structure to avoid possible sampling risks. Summary of the invention

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1

[0054] like Figure 1-Figure 3 As shown, this embodiment provides a jacket-cooled sampler, which includes a sampler body 1, an inlet and outlet system 2 and a cooling system 4, wherein the inlet and outlet system 2 is connected to the sampler body 1, and the inlet and outlet system 2 connects the sampler body 1 with the bottom of the distillation tower to complete the sampling and detection of the residual liquid at the bottom of the tower; and the cooling system 4 is arranged on the outside of the sampler body 1 to cool down the high-temperature residual liquid inside the sampler body 1 to avoid the safety risks brought by the residual liquid of high-boiling point impurities with relatively high temperature during the sampling process.

[0055] It should be noted that the specific shape of the sampler body 1 in this embodiment is not limited, and can be as follows: Figure 2 The cylindrical shape shown may also be a cylindrical shape. A sampling cavity 11 is provided inside the sampler body 1 for sampling and / or containing the high-temperature residual liquid at the bottom of the tower.

[0056] Furthermore, during the installation process, the sampler body 1 is vertically arranged along the length direction of the sampler body 1, so that the residual liquid at the bottom of the tower can flow out smoothly for sampling under the action of gravity.

[0057] like Figure 1 and Figure 2 As shown, the feed-in and feed-out system 2 comprises a feed pipe 21 and a feed pipe 22, wherein one end of the feed pipe 21 is connected to the bottom of the distillation tower, and the other end of the feed pipe 21 is connected to the end of the sampler body 1 in the vertical direction and communicated with the sampling cavity 11. The sampler body 1 is connected to the bottom of the distillation tower through the feed pipe 21, so that the high-temperature residual liquid after distillation can flow into the sampling cavity 11 of the sampler body 1.

[0058] Furthermore, one end of the discharge pipe 22 in the above-mentioned feed and discharge system 2 is connected to the other end of the sampler body 1 in the vertical direction, and is communicated with the sampling chamber 11, and the other end is connected to a discharge head (not shown in the figure). The cooled bottom residual liquid is discharged through the discharge pipe 22 for real-time quality monitoring.

[0059] Furthermore, control valves 3 are provided on both the feed pipe 21 and the discharge pipe 22 for controlling the sampling process. It should be noted that there is no restriction on the type of the control valve 3 in this embodiment, and it can be a solenoid valve or a manually controlled ball valve. By opening and closing the valve, the high-temperature residual liquid flowing out of the bottom of the distillation tower is controlled. The control system can also be connected to automatically control the sampling time, flow rate and other factors to achieve intelligent control of the sampling.

[0060] Furthermore, the above-mentioned cooling system 4 includes a water inlet pipe 41 and a water outlet pipe 42, a cooling cylinder 43 is arranged between the water inlet pipe 41 and the water outlet pipe 42, and the cooling cylinder 43 is sleeved on the outside of the sampler body 1, and a cooling cavity 45 is formed between the inner wall of the cooling cylinder 43 and the outer wall of the sampler body 1. Cooling water is introduced into the cooling cavity 45 to realize cooling of the high-temperature residual liquid inside the sampler body 1.

[0061] Furthermore, the water inlet pipe 41 is arranged on one side of the cooling cylinder 43, and the water outlet pipe 42 is arranged on the other side of the cooling cylinder 43, and both the water inlet pipe 41 and the water outlet pipe 42 are connected to the inner cavity of the cooling cylinder 43, and the water inlet pipe 41 and the water outlet pipe 42 are staggered in the vertical direction at the connection position of the cooling cylinder 43. The water inlet pipe 41 can be arranged on the top and the water outlet pipe 42 can be arranged on the bottom; or the water outlet pipe 42 can be arranged on the top and the water inlet pipe 41 can be arranged on the bottom.

[0062] In this embodiment, the water outlet pipe 42 is preferably at the top and the water inlet pipe 41 is at the bottom, which forms a countercurrent cooling path and enables a more complete heat exchange between the cooling water and the sampler body 1 .

[0063] It should be noted in this embodiment that control valves 3 may also be provided on the water inlet pipe 41 and the water outlet pipe 42 to control the inflow and outflow of cooling water by the control valves 3 so as to accurately control the cooling process.

[0064] It should be noted in this embodiment that the high-temperature residual liquid in the sampler body 1 can be cooled during the flow process, or can be cooled after passing through the water inlet pipe 41 and the water outlet pipe 42 of the pipe wall of the control valve 3.

[0065] And if Figure 1 As shown, the water inlet pipe 41 and the water outlet pipe 42 in this embodiment are both connected to the external cold source, so that the cooling system 4 can be operated in a circulation manner, saving cooling water resources and thus saving costs.

[0066] It should be noted that the cold source in this embodiment is not specifically limited and can be an existing device such as a mold temperature controller.

[0067] Further, the cooling cylinder 43 comprises a cooling cylinder body and a sealing cover 44, wherein the cooling cylinder body is U-shaped, a mounting hole is provided at the bottom of the U-shaped cooling cylinder body, the discharge pipe 22 is arranged through the mounting hole, and the discharge pipe 22 is connected to the cooling cylinder body by welding, and a sealing cover 44 is welded on the top of the cooling cylinder body, the sealing cover 44 is in an inverted U shape, and a mounting hole is also provided on the top, the feed pipe 21 is arranged through the mounting hole, and the feed pipe 21 is welded to the sealing cover 44;

[0068] In this embodiment, the cooling cylinder body and the sealing cover 44 are sleeved on the outside of the sampler body 1, and a cooling cavity 45 is formed between the sampler body 1. In this embodiment, the cooling water flow path in the cooling cavity 45 is as follows: Figure 3 As shown, after water enters the water inlet pipe 41, the cooling water diffuses to the surroundings along the outer wall of the sampler body 1 (including the arc-shaped portion at the bottom of the cooling cavity 45), and continues to rise after the bottom is filled, and flows out from the water outlet pipe 42, wherein the cooling water flowing out of the water outlet pipe 42 is composed of the water entering from the bottom and the water entering from the arc-shaped portion at the top of the cooling cavity 45.

[0069] It should be noted in this embodiment that, since the cooling water may produce impurities that affect the circulation process, a filtering device may be provided on the water inlet pipe 41 in this embodiment. The filtering device is a prior art and will not be described in detail here. The arc-shaped portion at the bottom of the cooling channel 45 may also be used to precipitate and collect impurities during the cooling water circulation process to avoid blockage caused by impurities that affect the cooling process.

[0070] It should be noted that in the present embodiment, during the cooling process, in order to further improve the cooling efficiency, the cooling of the high-temperature residual liquid inside the sampler body 1 is accelerated by increasing the cooling water flow rate, and the high-speed flowing cooling water will fill the entire cooling cavity 45 for heat exchange.

[0071] Embodiment 2

[0072] In order to simplify the installation structure of the jacket cooling sampler in the first embodiment and reduce the pipeline setting, on the one hand, the cold source is set close to the jacket cooling sampler, shortening the cooling water walking path and improving the circulation efficiency of the cooling water. On the other hand, this embodiment sets the water inlet pipe 41 and the water outlet pipe 42 on the same side of the cooling cylinder 43, reducing the pipelines connecting the water inlet pipe 41 and the water outlet pipe 42 with the cold source, avoiding a large loss of cooling water head caused by pipeline bending, thereby improving the cooling efficiency from the side. In addition, the reduction of pipeline settings can also reduce the expenditure of equipment costs, further saving costs.

[0073] like Figure 4-Figure 7As shown, in this embodiment, based on the first embodiment, the water inlet pipe 41 and the water outlet pipe 42 are arranged on the same side, and the water inlet pipe 41 is further preferably located at the bottom and the water outlet pipe 42 is located at the top, wherein the water inlet pipe 41 and the water outlet pipe 42 are not only located on the same side, but also located in the same plane in the vertical direction, thereby shortening the length of the pipeline connected to the cold source.

[0074] Furthermore, since the water inlet pipe 41 and the water outlet pipe 42 are arranged on the same side, the flow rate of the cooling water on both sides of the cooling cavity 45 (the side close to the water inlet pipe 41 and the side away from the water inlet pipe 41) is uneven, which easily causes a temperature difference of the cooling water on both sides, affecting the cooling effect. Therefore, in this embodiment, a flow-blocking reversing plate 46 is further arranged in the cooling cavity 45. The flow-blocking reversing plate 46 is as shown in FIG. Figure 4 and Figure 5 As shown, it is arranged close to one side of the water inlet pipe 41 or the water outlet pipe 42.

[0075] The cooling cavity 45 near the water inlet pipe 41 or the water outlet pipe 42 is blocked and drained by the flow-blocking reversing plate 46 to make it flow in the reverse direction, thereby stirring the cooling water flow in the cooling cavity 45 area on both sides, making the cooling water temperature on both sides more uniform, thereby making the high-temperature residual liquid inside the sampler body 1 cool more evenly.

[0076] It should be noted that in this embodiment, Figure 6 As shown, the above-mentioned flow-blocking reversing plate 46 is symmetrically arranged along the plane formed by the axis of the water inlet pipe 41 and the water outlet pipe 42, and the cooling water flowing vertically upward from the water inlet pipe 41 is diverted to both sides, so as to fully stir the cooling water flow in each part.

[0077] And if Figure 7 As shown, the bottom surface of the flow-blocking reversing plate 46 in this embodiment is provided with a guide surface 1 461 and a guide surface 2 462, wherein the guide surface 1 461 and the guide surface 2 462 are symmetrically distributed about the horizontal center line of the flow-blocking reversing plate 46, and the guide surface 1 461 and the guide surface 2 462 are both inclined upward from the middle, and on one side of the horizontal aspect, they are inclined from the inner wall side of the cooling cylinder 43 to the outer wall side of the sampler body 1, wherein the height of the end close to the sampler body 1 is higher than that of the end close to the cooling cylinder 43. Through the provision of the guide surface 1 461 and the guide surface 2 462, the cooling water flow is smoother, the head loss caused by the impact with the flow-blocking reversing plate 46 is reduced, and the cooling water is further fully contacted with the sampler body 1, the probability of direct contact between the outer cooling water and the sampler body 1 is increased, and the cooling efficiency is thereby improved.

[0078] Furthermore, it should be noted that in this embodiment, the baffle plate 46 is semicircular, blocking half of the cooling cavity 45 of the radial cross section of the sampler body 1, and the baffle plate 46 is preferably installed on the inner wall of the cooling tube 43 to facilitate the socket installation of the cooling tube 43, and the baffle plate 46 is preferably made of copper. By matching the copper baffle plate 46 with the sampler body 1, the outer surface of the sampler body 1 (steel) is not easily damaged during installation, thereby improving the service life of the sampler body 1, and the copper baffle plate 46 has higher thermal conductivity, which accelerates the heat transfer from the sampler body 1 to the cooling tube 43, thereby indirectly improving the heat dissipation efficiency.

[0079] In this embodiment, the flow path of the cooling water is as follows: Figure 5 As shown, the cooling water entering from the water inlet pipe 41 diffuses around along the outer wall of the sampler body 1, and continues to rise after the bottom is filled. The cooling water flow near the side of the water outlet pipe 42 is blocked by the flow-blocking reversing plate 46 and flows to the opposite side. The cooling water gathered on the opposite side is pressed upward, and after passing the flow-blocking reversing plate 46, it flows to the side near the water outlet pipe 42, thereby improving the degree of mixing and exchange of water flows on both sides. The cooling water flowing out of the water outlet pipe 42 is composed of the water inlet at the bottom and the water inlet at the arc-shaped part of the top of the cooling cavity 45.

[0080] Embodiment 3

[0081] like Figure 8 and Fig. 9 As shown, based on the second embodiment, in order to further reduce the head loss of cooling water, the second sealing cover 47 is used in this embodiment to replace the sealing cover 44 on the cooling tube 43. The second sealing cover 47 in this embodiment is arranged to fit the outer side surface of the top of the sampler body 1 to avoid forming an arc-shaped cooling cavity 45 at the bottom with the sampler body 1, thereby reducing the head loss caused by the mutual impact of the water inlet at the top arc-shaped part of the cooling cavity 45 on the water inlet at the bottom during the flow of cooling water, thereby reducing the flow rate of cooling water entering the outlet pipe 42, affecting the speed of the cooling cycle.

[0082] Embodiment 4

[0083] Since the present application adopts high-speed flowing cooling water for cooling, when the cooling water enters the cooling cavity 45 from the water inlet pipe 41, the high-speed flowing cooling water will impact the outer wall of the sampler body 1 at the water inlet (the position where the water inlet pipe 41 and the cooling cavity 45 are connected). After long-term operation, the sampler body 1 will be subjected to continuous impact and wear, which can easily affect the service life of the sampler body 1.

[0084] In order to further improve the service life of the sampler body 1, this embodiment is based on the third embodiment, and a diffusion component 48 is provided at the connection between the water inlet pipe 41 and the cooling cylinder 43. Fig.10 and Fig.11 As shown, the diffusion component 48 includes a water inlet box 481 welded to the cooling cylinder 43, and the water inlet box 481 is provided with a U-shaped chamber near the sampler body 1. The outer end of the water inlet box 481 is connected with a water inlet pipe 41, and the water inlet pipe 41 is connected to the chamber of the water inlet box 481. A diffusion table 482 is provided in the chamber, wherein the diffusion table 482 is conical, and the conical surface expands from the water inlet pipe 41 to the cooling cavity 45. The diffusion table 482 is welded in the chamber through a connecting rod, and the side edges of the chamber near the sampler body 1 are all provided with rounded corners to reduce obstruction to the water flow.

[0085] In this embodiment, a water inlet box 481 and a diffusion table 482 are provided so that the cooling water flowing out from the water inlet pipe 41 directly contacts the diffusion table 482, thereby reducing the impact of the cooling water on the sampler body 1. The conical surface of the diffusion table 482 cooperates with the inner wall of the chamber to form an inclined flow channel, thereby changing the flow direction of the cooling water, reducing the head loss caused by the cooling water directly impacting the outer wall of the sampler body 1 vertically, accelerating the flow speed of the cooling water from the bottom to the top, and improving the cooling efficiency.

[0086] like Fig.11 As shown, in this embodiment, the flow path of the cooling water entering from the water inlet pipe 41 is that the cooling water impacts the diffusion platform 482, diffuses to the surroundings of the diffusion platform 482, is redirected by the cone surface, and diffuses obliquely from the inner side of the water inlet box 481 to the surroundings.

[0087] Embodiment 5

[0088] Under the premise of ensuring that the high-speed cooling water flow does not directly impact the sampler body 1, the head loss of the water flow is further reduced, such as Figure 12-14 As shown, this embodiment is based on the fourth embodiment, and the diffusion component 48 is replaced by the diffusion component 2 49;

[0089] The above-mentioned diffusion component 49 includes a water inlet box 491 connected to the cooling cylinder 43, and a water inlet cavity is opened inside the water inlet box 491. The water inlet cavity is in the shape of a frustum, and the side wall of the water inlet cavity is a diffusion surface 492 that expands from the end of the water inlet pipe 41 to the end of the cooling cavity 45. A diffusion table 493 is connected to the bottom of the diffusion surface 492, and the outer side surface of the diffusion table 493 is a conical surface, which expands from the end of the water inlet pipe 41 to the end of the cooling cavity 45; wherein the conical surface and the frustum surface form an inclined and uniform water channel.

[0090] What should be noted in this embodiment is that the bottom surface of the diffusion table 493 is connected to the inner wall of the water inlet cavity, blocking the water from flowing to the arc-shaped part at the bottom of the cooling cavity 45, further reducing the downward diversion of the water flow, reducing the head loss, and evenly tilting the water channel to smoothly guide the water flow, change the direction of the cooling water, and flow it upward at an angle, reducing the head loss caused by the cooling water directly impacting the outer wall of the sampler body 1 vertically.

[0091] like Fig.14 As shown, in this embodiment, the flow path of the cooling water entering from the water inlet pipe 41 is that the cooling water impacts the diffusion table 493 and diffuses around the diffusion table 493. Due to the bottom blockage, it flows to the horizontal sides and the upward direction, and is redirected through a uniformly inclined water channel to diffuse outward from the inner side of the water inlet box 491.
