Description

Technical Field

[0001] This utility model relates to the field of reboiling system technology, and in particular to a tower and a reboiling system. Background Technology

[0002] In the distillation process in the chemical and petroleum refining industries, the reboiler is a key piece of equipment. Its function is to provide a continuous upward flow of steam to the distillation column in order to maintain the mass and heat transfer required for the distillation process.

[0003] However, in existing technologies, the steam generated by the reboiler is typically introduced directly to the bottom of the tower. Due to fluctuations in operating conditions, the steam generation efficiency is unstable, resulting in uneven airflow distribution when it enters the tower. This uneven distribution can lead to problems such as decreased tray efficiency and insufficient mass and heat transfer. Especially when the steam flow rate is excessively high instantaneously, the high-speed airflow can directly impact the trays, internal components, and even the tower body, potentially causing equipment vibration and, over time, even damage to the tower structure.

[0004] Therefore, there is an urgent need for a tower and reboiling system that can allow steam to flow evenly into the tower. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low mass and heat transfer efficiency inside towers caused by uneven steam flow distribution in the prior art.

[0006] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a tower device, comprising:

[0007] The shell extends along the height direction and has a top end and a bottom end, and has an internal cavity;

[0008] An air outlet is located at the top.

[0009] The liquid outlet is located at the bottom end;

[0010] An air inlet is located on the side wall of the housing, between the air outlet and the liquid outlet;

[0011] A buffer component, disposed in the cavity, has a guide tube and a buffer plate. The guide tube extends along the length direction, with one end facing the air inlet and connected to the inner wall of the housing. The buffer plate extends along the height direction and is connected to the other end of the guide tube. Along the length direction, the buffer plate is spaced apart from the inner wall of the housing.

[0012] The guide tube is provided with multiple first through holes, and the buffer plate is provided with multiple second through holes.

[0013] By adopting the above technical solution, the air inlet is located in the middle of the tower, which effectively extends the gas-liquid contact path, avoids steam "short circuit", and makes mass and heat transfer more complete. Compared with traditional towers where steam enters from the bottom, it can also balance the fluid load distribution in the tower and reduce the pressure drop at the bottom.

[0014] By incorporating a buffer component, the airflow entering from the inlet can be initially buffered, effectively reducing its direct impact on the inner wall of the tower. Furthermore, by setting multiple first and second through holes on the buffer component, the concentrated large airflow can be dispersed into multiple uniform small airflows, thereby achieving a uniform distribution of airflow on the inner wall of the tower.

[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower device in which a plurality of first through holes are uniformly and spaced apart, and a plurality of second through holes are uniformly and spaced apart.

[0016] By adopting the above technical solution, the first and second through holes are set to be uniformly and spaced apart, forming an optimized airflow distribution network, which ensures that the airflow flows out uniformly and stably on the cross-section of the tower, effectively avoiding local eddies or impacts.

[0017] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower device, wherein the guide tube, the buffer plate, and the shell together form a buffer chamber, and the buffer chamber is used to accommodate and buffer the steam flow entering from the air inlet.

[0018] By adopting the above technical solution, a buffer chamber formed by the guide tube, buffer plate, and shell provides a dedicated expansion and pressure stabilization space for the airflow entering the tower. This not only effectively consumes the initial kinetic energy of the airflow and reduces its direct impact on the inner wall of the tower, but also initially homogenizes the airflow distribution, thereby ensuring the stable operation of the tower and extending its service life.

[0019] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower device, which further includes:

[0020] Multiple trays are disposed in the cavity, and each tray is connected to the inner wall of the shell; along the height direction, the multiple trays are respectively disposed between the gas outlet and the buffer, and between the buffer and the liquid outlet, and the multiple trays are spaced apart;

[0021] Each of the trays is provided with a plurality of third through holes, and each of the third through holes penetrates the tray along the height direction.

[0022] By employing the above technical solution, a gas-liquid contact interface is constructed within the cavity by setting multiple third through holes at intervals along the height direction of the tower plate. This provides a sufficient and continuous mass and heat transfer channel for the rising vapor and the falling liquid, thereby ensuring high separation efficiency.

[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower device, wherein one end of each tower plate is connected to the inner wall of the shell, the other end of the tower plate is spaced apart from the inner wall of the shell, and multiple tower plates are spaced apart and staggered.

[0024] The tray also includes:

[0025] An overflow plate extends along the height direction, is located at the other end of the tower plate, and is spaced apart from the inner wall of the shell.

[0026] By adopting the above technical solution, the transverse flow path of liquid on the tray and the vertical upward path of vapor are forcibly defined by the staggered arrangement of the trays and the configuration of overflow plates, forming an efficient cross-flow contact, thereby significantly extending the contact time and path of the gas and liquid phases and improving the mass transfer efficiency.

[0027] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower device, which further includes:

[0028] Multiple blister packs correspond one-to-one with the third through hole. Each blister pack includes a baffle and multiple support columns. The baffle faces the third through hole, is located above the tray, and is spaced apart from the tray. The multiple support columns are evenly spaced along the outer periphery of the baffle. One end of each support column is connected to the baffle, and the other end is connected to the tray.

[0029] By adopting the above technical solution, by setting a bubble cap consisting of a baffle and a support column for each third through hole, the rising steam is forced to pass through the liquid layer on the tower plate and dispersed into fine bubbles, thereby greatly increasing the contact area between the gas and liquid phases and realizing efficient mass and heat transfer.

[0030] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower device, which further includes:

[0031] The manifold, along the height direction, is located between the bottommost tray and the bottom end, and is connected to the inner wall of the shell;

[0032] The busbar is provided with a fourth through hole, which penetrates the busbar along the height direction and is directly opposite to the plurality of third through holes.

[0033] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tower, wherein the liquid outlet includes a first liquid outlet and a second liquid outlet, and the first liquid outlet and the second liquid outlet are symmetrically arranged along the length direction.

[0034] The tower also includes:

[0035] The diverter plate extends along the height direction, with one end connected to the bottom end and the other end spaced apart from the manifold plate; along the length direction, the diverter plate is located between the first liquid outlet and the second liquid outlet, and is located directly below the fourth through hole.

[0036] By adopting the above technical solution, a high-efficiency fluid collection and distribution system is formed by setting a manifold plate directly opposite the tray at the bottom of the tower and a diverter plate located between the two liquid outlets. This ensures that the liquid falling from the tray is smoothly collected and evenly distributed to each liquid outlet, thus guaranteeing stable discharge and tower pressure balance.

[0037] This utility model also discloses a reboiling system, comprising:

[0038] The tower as described in any of the above embodiments;

[0073] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0074] refer to Figure 1 , Figure 2This application provides a tower 100, including: a shell 110, an air outlet 120, a liquid outlet 130, an air inlet 140, a buffer 150, a tower plate 160, a bubble cap 170, a manifold 180, and a diverter 190. The shell 110 extends along the height direction and has a top end 111 and a bottom end 112, and has an internal cavity 113.

[0075] refer to Figure 1 , Figure 2 In this embodiment, the gas outlet 120 is located at the top end 111 and is used to output gas; the liquid outlet 130 includes a first liquid outlet 131 and a second liquid outlet 132, which are symmetrically arranged along the length direction and located at the bottom end 112, and are used to discharge liquid; the air inlet 140 is located on the side wall of the housing 110, between the gas outlet 120 and the liquid outlet 130, and is used to receive steam flow.

[0076] In some possible implementations, only one liquid outlet 130 may be provided at the bottom end 112, which is sufficient to discharge liquid. This application does not limit this implementation.

[0077] By placing the air inlet 140 in the middle of the tower 100, the gas-liquid contact path is effectively extended, avoiding steam "short circuit" and making mass and heat transfer more complete. Compared with traditional towers where steam enters from the bottom, it can also balance the fluid load distribution in the tower 100 and reduce the pressure drop at the bottom 112.

[0078] refer to Figure 1 , Figure 2 In this embodiment, the buffer 150 is disposed in the cavity 113. The buffer 150 has a guide tube 151 and a buffer plate 152. The guide tube 151 extends along the length direction ( Figure 1 Extending in the X direction, one end faces the air inlet 140 and is welded to the inner wall 114 of the housing 110; the buffer plate 152 extends along the height direction ( Figure 1 Extending in the Z-direction, it connects to the other end of the guide tube 151. Along its length, the buffer plate 152 is spaced apart from the inner wall 114. The guide tube 151 is a cylindrical structure, and the buffer plate 152 is a circular plate structure. The cylindrical structure has circumferential symmetry, which enables the steam flow to achieve a preliminary uniform distribution inside the guide tube 151.

[0079] In some possible implementations, the shape of the guide tube 151 includes, but is not limited to, a cylinder, and can be a rectangular, conical, arc-shaped, or other cylindrical structure. The shape of the buffer plate 152 includes, but is not limited to, a circle, and can be adapted to the shape of the end of the guide tube 151.

[0080] In some possible implementations, the connection between the guide tube 151 and the inner wall 114 may include, but are not limited to, welding, and may be a fixed connection such as bonding, threaded connection, or interference fit. The embodiments of this application do not limit this.

[0081] refer to Figure 2 , Figure 3 , Figure 4 In this embodiment, the guide tube 151 is provided with a plurality of first through holes 1511, and the buffer plate 152 is provided with a plurality of second through holes 1521. The plurality of first through holes 1511 are evenly and spaced apart, and the plurality of second through holes 1521 are evenly and spaced apart.

[0082] By setting the first through hole 1511 and the second through hole 1521 to be uniformly and spaced apart, they together form an optimized airflow distribution network, ensuring that the airflow flows out uniformly and stably on the cross-section of the tower 100, effectively avoiding local eddies or impacts.

[0083] In some possible implementations, the multiple first through holes 1511 and second through holes 1521 can be arranged non-uniformly as long as they can allow airflow to be discharged. This application does not limit this.

[0084] By providing a buffer 150, the airflow entering from the air inlet 140 can be initially buffered, effectively reducing its direct impact on the inner wall 114 of the tower 100. Furthermore, by providing multiple first through holes 1511 and second through holes 1521 on the buffer 150, the concentrated large airflow can be dispersed into multiple uniform small airflows, thereby achieving a uniform distribution of airflow on the inner wall 114 of the tower 100.

[0085] refer to Figure 2 , Figure 3 , Figure 4 In this embodiment, the guide tube 151 and the buffer plate 152 are integrated into one structure, which enhances the overall structural strength and stability, avoids the risk of leakage at the connection, simplifies the manufacturing and installation process, and improves the reliability of the equipment.

[0086] In some possible implementations, the guide tube 151 and the buffer plate 152 may also be separate structures, which may be fixedly connected by welding, bonding or other methods. This application does not limit this aspect.

[0087] refer to Figure 2 , Figure 3 , Figure 4 In this embodiment, the guide tube 151, the buffer plate 152, and the shell 110 together form a buffer chamber 153, which is used to contain and buffer the steam flow entering from the air inlet 140.

[0088] The buffer chamber 153, formed by the guide tube 151, the buffer plate 152, and the shell 110, provides a dedicated expansion and pressure stabilization space for the airflow entering the tower 100. This not only effectively consumes the initial kinetic energy of the airflow and reduces its direct impact on the inner wall 114 of the tower 100, but also initially homogenizes the airflow distribution, thereby ensuring the stable operation of the tower 100 and extending its service life.

[0089] refer to Figure 2 , Figure 3 In this embodiment, 10 trays 160 are disposed in the cavity 113, and the outer periphery of each tray 160 is welded to the inner wall 114 of the shell 110. Along the height direction, 6 trays 160 are disposed between the gas outlet 120 and the buffer 150, and 4 trays 160 are disposed between the buffer 150 and the liquid outlet 130. The multiple trays 160 are spaced apart. The shape of the trays 160 is adapted to the cross-section of the cavity 113 along the length direction.

[0090] In some possible implementations, the number of trays 160 includes, but is not limited to, 10, but can be 2, 8, 15, or more, etc., and the embodiments of this application do not limit this. The distribution of the multiple trays 160 can be selected according to actual needs, and the embodiments of this application do not limit this.

[0091] In some possible implementations, the connection between the tray 160 and the inner wall 114 may include, but is not limited to, welding, and may be a fixed connection such as bonding, threaded connection, or interference fit. The embodiments of this application do not limit this.

[0092] By setting multiple trays 160 at intervals along the height direction, a gas-liquid contact interface is constructed in the cavity 113, providing a sufficient and continuous mass and heat transfer channel for the rising vapor and the falling liquid, thereby ensuring high separation efficiency.

[0093] refer to Figure 2 , Figure 3 In this embodiment, along the length direction, one end of each tray 160 is connected to the inner wall 114 of the shell 110, and the other end of the tray 160 is spaced apart from the inner wall 114 of the shell 110. Multiple trays 160 are spaced apart and staggered. At this time, there is a gap between the tray 160 and the inner wall 114, forming a steam channel.

[0094] refer to Figure 2 , Figure 3 In this embodiment, the tray 160 further includes an overflow plate 162, which extends along the height direction, is disposed at the other end of the tray 160, and is spaced apart from the inner wall 114 of the shell 110.

[0095] In some possible implementations, tray 160 may not include overflow tray 162, and this application does not limit this implementation.

[0096] By staggering the trays 160 and configuring the overflow plates 162, the lateral flow path of the liquid on the trays 160 and the vertical upward path of the vapor are forcibly defined, forming an efficient cross-flow contact, thereby significantly extending the contact time and path between the gas and liquid phases and improving the mass transfer efficiency.

[0097] refer to Figure 2 , Figure 3 and combined Figure 5 , Figure 6 In this embodiment, each tray 160 is provided with multiple third through holes 161, each third through hole 161 penetrating the tray 160 along the height direction. Multiple bubble caps 170 correspond one-to-one with the multiple third through holes 161. Each bubble cap 170 includes a baffle 171 and three support columns 172. The baffle 171 faces the third through hole 161, is located above the tray 160, and is spaced apart from the tray 160. The three support columns 172 are evenly and spaced apart along the outer periphery of the baffle 171. One end of each support column 172 is connected to the baffle 171, and the other end is connected to the tray 160.

[0098] In some possible implementations, the number of support columns 172 may include, but is not limited to, three, but may be two, four, five, or more, capable of supporting the baffle 171, and the gaps between the support columns 172 may allow gas or liquid to pass through.

[0099] By providing a bubble cap 170 consisting of a baffle 171 and a support column 172 for each third through hole 161, the rising steam is forced to pass through the liquid layer on the tray 160 and dispersed into fine bubbles, thereby greatly increasing the contact area between the gas and liquid phases and achieving efficient mass and heat transfer.

[0100] refer to Figure 2 , Figure 3 In this embodiment, the manifold 180 extends along the length direction and is located between the bottom tray 160 and the bottom end 112 along the height direction. The outer periphery of the manifold 180 is connected to the inner wall 114 of the shell 110. The manifold 180 is provided with a fourth through hole 181, which penetrates the manifold 180 along the height direction and is directly opposite to a plurality of third through holes 161.

[0101] refer to Figure 2 , Figure 3In this embodiment, the diverter plate 190 extends along the height direction, with one end connected to the bottom end 112 and the other end spaced apart from the manifold plate 180; along the length direction, the diverter plate 190 is located between the first liquid outlet 131 and the second liquid outlet 132, and is located directly below the fourth through hole 181. The diverter plate 190 is used to evenly distribute the liquid at the bottom end 112 to the first liquid outlet 131 and the second liquid outlet 132.

[0102] By setting a manifold 180 directly opposite the tray 160 at the bottom of the tower and a diverter 190 located between the two liquid outlets, a highly efficient fluid collection and distribution system is formed, ensuring that the liquid falling from the tray 160 is smoothly collected and evenly distributed to each liquid outlet, thus ensuring stable discharge and tower pressure balance.

[0103] refer to Figure 7 , Figure 8 This application also provides a reboiling system 200, comprising: a tower 100 as described in any of the above embodiments, a reboiler 210, an air inlet pipe 220, a first liquid outlet pipe 231, and a second liquid outlet pipe 232. The reboiler 210 extends along its length, with a first outlet 211 and a second outlet 212 at its top, and a first inlet 213 and a second inlet 214 at its bottom. One end of the air inlet pipe 220 is connected to the first outlet 211 and the second outlet 212, respectively, and the other end of the air inlet pipe 220 is connected to the air inlet 140 of the tower 100. One end of the first liquid outlet pipe 231 is connected to the first inlet 213, and the other end of the first liquid outlet pipe 231 is connected to the first liquid outlet 131 of the tower 100. One end of the second liquid outlet pipe 232 is connected to the second inlet 214, and the other end of the second liquid outlet pipe 232 is connected to the second liquid outlet 132 of the tower 100.

[0104] The reboiler 210 includes two aluminum plate-fin heat exchangers 240 and a connecting plate 250. Along the length direction, the two aluminum plate-fin heat exchangers 240 are arranged side by side inside the reboiler 210, and the connecting plate 250 is provided between the two aluminum plate-fin heat exchangers 240. The connecting plate 250 is used to prevent liquid from passing between the two aluminum plate-fin heat exchangers 240.

[0105] In some possible implementations, the number of aluminum plate-fin heat exchangers 240 includes, but is not limited to, two, and may be three, four, six, or more.

[0106] The working principle of this reboiling system 200:

[0107] The reboiler 210 heats the liquid inside it, and the resulting steam flow passes through the first outlet 211, the second outlet 212 and the inlet pipe 220 in sequence, and is introduced into the inlet 140 of the tower 100.

[0108] After the steam flow enters the tower 100, it first enters the buffer 150, where it undergoes initial distribution and buffering through the first through-hole 1511 and the second through-hole 1521. Subsequently, the airflow splits into two paths:

[0109] A portion of the steam flows upward, passing through the third through hole 161 and its corresponding bubble cap 170 on each tray 160 in sequence. After sufficient mass and heat transfer with the liquid layer on the tray 160, it is finally discharged from the outlet 120.

[0110] The other part of the steam flows downwards, specifically along two paths: one is along gas path a ( Figure 8 As shown in (a), it flows downward through the third through-hole 161 of the lower tray 160 and the bubble cap 170; the second is along the gas path b ( Figure 8 As shown in Figure b), the material flows downward through the gap between the tray 160 and the inner wall 114 of the shell 110.

[0111] The steam from gas path a and gas path b eventually converges at the fourth through hole 181 of the manifold 180 and is distributed by the flow guide of the distributor 190. At this time, the partially condensed fluid is discharged from the first liquid outlet 131 and the second liquid outlet 132 respectively, and returns to the reboiler 210 through the first liquid outlet pipe 231 and the second liquid outlet pipe 232, thus completing a complete working cycle.

[0112] The heating process described above is based on the principle of thermosiphon circulation. The density of the gas-liquid mixture generated in the reboiler 210 decreases, and driven by the density difference between it and the fluid in the tower 100, the gas-liquid mixture flows into the interior of the tower 100. Gas-liquid separation occurs within the tower: the gas rises and exits through the outlet 120, while the liquid collects at the bottom 112 of the tower 100 and re-enters the circulation. The entire process proceeds spontaneously based on thermodynamic equilibrium, requiring no external mechanical power input.

[0113] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
