Description

Technical Field

[0001] The present application relates to the field of distillation equipment, and in particular to a distillation tower with an anti-clogging structure. Background Art

[0002] As an important chemical equipment, distillation tower is widely used in the fields of petroleum, chemical industry, etc. Traditional distillation tower mainly adopts floating valve tray structure, and the material separation is achieved by opening and closing the floating valve on the tray. This structure is simple and reliable, easy to operate and maintain, and can effectively improve separation efficiency and reduce energy consumption.

[0003] However, with the continuous expansion of industrial production scale and the continuous improvement of technical requirements, the existing floating valve tray distillation tower faces many challenges. The most common one is that the floating valve tray distillation tower may have the problem of floating valve tray blockage during use. For example, when certain components in the material crystallize or coke on the surface of the floating valve, scaling will occur, affecting the movement of the floating valve, causing the movement of the floating valve to be blocked, or even completely fail.

[0004] To solve this problem, common solutions include cleaning the tray regularly to remove accumulated impurities and using more corrosion-resistant materials to make the float valve to extend its service life. Although these methods have alleviated the clogging problem of the float valve tray to a certain extent, they still have certain limitations and shortcomings. Therefore, how to design an effective anti-clogging structure to ensure that the tray always maintains a good working condition during long-term use has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to solve the problems in the background technology and reduce the probability of tower plate blockage, the present application provides a distillation tower with an anti-blocking structure.

[0006] The present application provides a distillation tower with an anti-clogging structure adopts the following technical solution: A distillation tower with an anti-clogging structure, comprising: A tower plate, wherein a sieve hole is formed on the tower plate; A float is arranged on the upper side of the sieve hole, the diameter of the float is larger than the diameter of the sieve hole, and a plurality of concave patterns are formed on the peripheral wall of the float; A plurality of elastic arc plates are fixed on the upper side of the sieve hole in a centrally symmetrical manner. The upper ends of the plurality of elastic arc plates form an open end with a diameter smaller than the diameter of the float. A spacing is formed between adjacent elastic arc plates, and a gap is formed between the inner wall of the elastic arc plate and the peripheral wall of the float.

[0007] By adopting the above technical scheme, the float is placed on the upper side of the sieve hole and its diameter is larger than the diameter of the sieve hole. The float can fall on the upper side of the sieve hole under normal conditions, thereby closing the sieve hole and preventing the liquid on the tower plate from flowing directly from the sieve hole. When the gas phase flow rate is large during operation, the float is lifted higher, so that the gas phase can pass smoothly and can fully contact with the liquid phase on the tower plate. In addition, due to the concave grooves on the peripheral wall of the float, the float can automatically promote the floating rolling when the material flows, thereby reducing the accumulation of crystallization or coking of the material on the surface of the float. The multiple elastic arc plates are fixed on the upper side of the sieve hole in a centrally symmetrical manner, and the diameter of the open end formed at the upper end is smaller than the diameter of the float, which does not hinder the normal up and down floating of the float to realize the function similar to the float valve for material separation, and can also play a certain diversion and buffering role on the material during the material flow process, avoiding the accumulation of impurities in one place. In addition, due to the cooperation between the float and the elastic arc plate, the elastic arc plate can continuously vibrate during the rolling of the float, thereby effectively reducing the probability of tower plate blockage and ensuring that the tower plate can maintain a good working condition during long-term use.

[0008] Optionally, a floating bead is embedded on one side of the elastic arc plate that is capable of contacting the floating ball.

[0009] By adopting the above technical solution, a floating bead is embedded on one side of the elastic arc plate that can resist the float. The floating bead can reduce the friction between the float and the elastic arc plate when they are in contact, so that the float can roll more smoothly when the gas phase flow rate changes, thereby further reducing the accumulation and crystallization of materials on the surface of the float and enhancing the anti-blocking effect. In addition, due to the concave patterns on the surface of the float, the airflow can push the float to roll, and the cooperation of the floating bead and the concave patterns can drive the continuous vibration of each elastic arc plate, further reducing the possibility of impurities adhering to and accumulating on the surface of the float or the elastic arc plate due to factors such as friction, thereby better reducing the probability of tower plate blockage and ensuring the stable operation of the distillation tower.

[0010] Optionally, also include: The shaping ring is fixed to the open ends of the plurality of elastic arc plates.

[0011] By adopting the above technical solution, a shaping ring is set to be fixed on the open end of multiple elastic arc plates, which can stabilize the upper end of the elastic arc plate, so that the elastic arc plate can still maintain a relatively stable shape and position under the impact of materials and the action of the floating ball for a long time, and prevent the elastic arc plate from deformation, displacement and the like, which affects the coordination with the floating ball and the diversion of materials, etc., which helps to maintain the effectiveness of the entire anti-blocking structure and reduce the occurrence of tower plate blockage. At the same time, the presence of the shaping ring can also effectively guide the uniform distribution of the gas phase and the liquid phase, avoid the occurrence of local overload, thereby better ensuring the stability and efficiency of the distillation process.

[0012] Optionally, also include: The clamping ring is connected to the roots of the plurality of elastic arc plates, and the clamping ring is clamped and fixed in the sieve hole.

[0013] By adopting the above technical solution, the clamping ring is connected to the roots of multiple elastic arc plates and is clamped and fixed in the sieve hole. The clamping method of the clamping ring is convenient for subsequent disassembly and maintenance, reducing maintenance costs and time, and facilitating timely replacement of the elastic arc plates and floats after they are damaged.

[0014] Optionally, also include: A horizontal ring, with an outer diameter larger than the diameter of the sieve hole, is fixed to the root of a plurality of elastic arc plates; The insert ring has an outer diameter the same as the diameter of the sieve hole, is integrally formed on the lower side of the horizontal ring, and is used to insert into the sieve hole; A plurality of elastic clamping plates are formed on the lower side of the inserting ring in a centrally symmetrical manner, and the outer end of each of the elastic clamping plates tends to extend away from the axis direction of the inserting ring.

[0015] By adopting the above technical scheme, the clamping ring includes a horizontal ring, an insert ring and multiple elastic clamping plates. The horizontal ring is fixed at the root of the elastic arc plate to play a connecting and supporting role. The insert ring can be inserted into the sieve hole for preliminary positioning, and the outer ends of the multiple elastic clamping plates tend to extend away from the axis direction of the insert ring. After the insert ring is inserted into the sieve hole, the clamping ring and the sieve plate are fixed, the elastic arc plate is fixed reliably, and the stability of the entire anti-blocking structure is maintained.

[0016] Optionally, the elastic card plate is a unidirectional thermal expansion plate; After the insert ring is inserted into the sieve hole, the outer end of the elastic clamping plate expands due to heat and can bend upward to press against the lower side of the tower plate.

[0017] By adopting the above technical solution, the elastic clamping plate is a one-way thermal expansion plate. After the insert ring is inserted into the sieve hole, as the temperature rises, the outer end of the elastic clamping plate can bend upward and press against the lower side of the tower plate, thereby ensuring that the clamping ring is firmly fixed in the sieve hole to prevent loosening due to vibration or other external factors. This not only improves the overall stability of the device, but also enhances the reliability of the anti-blocking structure, further reducing the probability of tower plate blockage.

[0018] Optionally, a connecting ring is fixed at the root of the plurality of elastic arc plates; The connecting ring is coaxially rotatably connected to the clamping ring.

[0019] By adopting the above technical solution, connecting rings are fixed at the roots of multiple elastic arc plates and the connecting rings are coaxially rotatably connected to the clamping rings, so that the elastic arc plates can rotate flexibly relative to the clamping rings. When the float generates forces in different directions acting on the elastic arc plates under conditions such as material impact, the elastic arc plates can adaptively rotate and adjust the angles to better buffer and disperse these forces, thereby avoiding damage to the elastic arc plates or other components and abnormal material accumulation due to uneven force, thereby reducing the probability of tower plate blockage and ensuring the normal operation of the distillation tower.

[0020] Optionally, the elastic arc plates are arranged obliquely to the axis of the sieve holes, and inclined flow channels are formed between adjacent elastic arc plates.

[0021] By adopting the above technical solution, the elastic arc plate is arranged obliquely to the axis of the sieve hole, and an inclined flow channel is formed between adjacent elastic arc plates. This design helps to guide the gas phase and liquid phase to be more evenly distributed on the entire tower plate, reduce overload in local areas, and further improve the material separation effect. At the same time, it effectively prevents impurities from accumulating in large quantities at a specific location, reduces the risk of blockage, and maintains the distillation tower in good working condition.

[0022] Optionally, a plurality of convex points are formed on the peripheral surface of the float.

[0023] By adopting the above technical solution, a plurality of convex points are formed on the peripheral surface of the float. When the material flows through the float, the convex points can further disrupt the flow state of the material, preventing the material from being stably attached to the surface of the float to form crystals or coking. At the same time, it can also disperse the material to a certain extent, reducing the accumulation of impurities in the float and the surrounding area. In addition, the elastic arc plate in contact with the float has a greater vibration, which can further reduce the probability of tower plate blockage and ensure the separation effect and normal operation of the distillation tower.

[0024] Optionally, also include: The auxiliary ball is located between the elastic arc plate and the floating ball, and the diameter of the auxiliary ball is smaller than the gap between the elastic arc plate and the peripheral wall of the floating ball.

[0025] By adopting the above technical solution, when the gas phase velocity increases, the auxiliary ball will float up and down with the airflow, which helps to further disperse the material and reduce the local pressure concentration phenomenon, thereby avoiding excessive accumulation of materials in a specific area and causing blockage. At the same time, the auxiliary ball can also continuously collide with the floating ball when the floating ball rises, increasing the vibration of the floating ball, and increasing the surface friction between the floating ball and the auxiliary ball, reducing the precipitation and accumulation of impurities on the surrounding wall of the floating ball, thereby reducing the possibility of tower plate blockage.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The float is placed on the upper side of the sieve hole and its diameter is larger than the diameter of the sieve hole. Under normal circumstances, the float can fall on the upper side of the sieve hole, thereby closing the sieve hole and preventing the liquid on the tower plate from flowing directly from the sieve hole. When the gas phase flow rate is large during operation, the float is lifted higher, so that the gas phase can pass smoothly and fully contact with the liquid phase on the tower plate. In addition, due to the concave patterns on the wall of the float, the float can automatically push the float to roll when the material flows, reducing the accumulation of crystallization or coking of the material on the surface of the float. Multiple elastic arc plates are fixed on the upper side of the sieve hole in a central symmetrical manner, and the diameter of the open end formed at the upper end is smaller than the diameter of the float, which does not hinder the normal up and down floating of the float to achieve a function similar to a float valve for material separation, and can also play a certain diversion and buffering role on the material during the material flow process, avoiding the accumulation of impurities in one place. In addition, due to the cooperation between the float and the elastic arc plate, the elastic arc plate can vibrate continuously during the rolling of the float, thereby effectively reducing the probability of tower plate blockage and ensuring that the tower plate can maintain a good working condition during long-term use. 2. The elastic arc plate is embedded with a floating bead on one side that can resist the floating ball. The floating bead can reduce the friction between the floating ball and the elastic arc plate when they are in contact, so that the floating ball can roll more smoothly when the gas phase flow rate changes, thereby further reducing the accumulation and crystallization of materials on the surface of the floating ball and enhancing the anti-blocking effect. In addition, due to the concave patterns on the surface of the floating ball, the airflow can push the floating ball to roll. At the same time, the cooperation of the floating bead and the concave patterns can drive the continuous vibration of each elastic arc plate, further reducing the possibility of impurities adhering to and accumulating on the surface of the floating ball or the elastic arc plate due to factors such as friction, thereby better reducing the probability of tower plate blockage and ensuring the stable operation of the distillation tower. 3. Setting shaping rings fixed on the open ends of multiple elastic arc plates can stabilize the upper ends of the elastic arc plates, so that the elastic arc plates can maintain a relatively stable shape and position under the impact of materials and the action of the floating ball for a long time, and prevent the elastic arc plates from deformation, displacement and other situations that affect the coordination with the floating ball and the diversion of materials, which helps to maintain the effectiveness of the entire anti-blocking structure and reduce the occurrence of tower plate blockage. At the same time, the existence of the shaping ring can also effectively guide the uniform distribution of the gas phase and the liquid phase, avoid the occurrence of local overload, and thus better ensure the stability and efficiency of the distillation process.

[0029] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0030] The inventors of the present application have discovered that a plate-type distillation tower may have a problem of plate clogging during use. For this reason, the present application mainly adopts the following distillation tower with an anti-clogging structure, which achieves the purpose of reducing the probability of plate clogging and ensuring that the plates are always in good working condition during long-term use. The present application is further described in detail below.

[0031] Example 1 Reference Figure 1 and Figure 2 A distillation tower with an anti-clogging structure comprises a tower body 1, in which a plurality of tower plates 2 are arranged in a vertical direction. A liquid receiving tank 21 is formed on the upper part of one side of the tower plate 2, and a downcomer 22 is vertically formed on the lower part of the other side of the tower plate 2. A plurality of sieve holes 23 are vertically opened on the tower plate 2 corresponding to the position between the liquid receiving tank 21 and the downcomer 22, and an overflow weir 24 protruding from the upper side of the tower plate 2 is fixed between the sieve holes 23 of the tower plate 2 and the downcomer 22. When a plurality of tower plates 2 are arranged, the downcomer 22 of the upper tower plate 2 corresponds to the position of the liquid receiving tank 21 of the lower tower plate 2.

[0032] The design of the tray 2 allows the rising steam and the descending liquid to fully contact on the tray 2, promoting the mass transfer process between the gas phase and the liquid phase, that is, the lighter components are transferred from the liquid phase to the gas phase, and the heavier components are transferred from the gas phase back to the liquid phase. The overflow weir 24, the downcomer 22 and other components can be used to guide the direction of liquid flow, ensuring that the liquid can flow from one tray 2 to the next tray 2 without falling directly, ensuring that each tray 2 can participate in the effective separation process.

[0033] Reference Figure 3 , a hard float 3 is arranged on the upper side of the sieve hole 23 of the tower plate 2. The surface of the float 3 can be coated with a corrosion-resistant coating, an antistatic coating, etc., or can be directly made of a corrosion-resistant material. The diameter of the float 3 is larger than the diameter of the sieve hole 23, and the surrounding wall of the float 3 is also formed with a plurality of grooves 31. The shape of the grooves 31 is not limited. In this embodiment, the grooves 31 preferably adopt irregular patterns. A plurality of elastic arc plates 4 are fixed on the upper side of the sieve hole 23 corresponding to the tower plate 2. The elastic arc plates 4 are made of stainless steel plates. The plurality of elastic arc plates 4 are arranged around the sieve hole 23 in a centrally symmetrical manner and in an inverted bowl-shaped structure, and a spacing is formed between adjacent elastic arc plates 4. The float 3 is located between multiple elastic arc plates 4. The diameter of the open ends formed by the upper ends of the multiple elastic arc plates 4 is smaller than the diameter of the float 3, and gaps are formed between the inner walls of the elastic arc plates 4 and the float 3. A floating bead 41 is also embedded on the inner side of the upper end of the elastic arc plate 4. When the float 3 rises to open the sieve hole 23, the surrounding wall of the float 3 can contact the floating bead 41.

[0034] The float 3 is placed on the upper side of the sieve hole 23 and its diameter is larger than that of the sieve hole 23. Under normal circumstances, the float 3 can fall on the upper side of the sieve hole 23, thereby closing the sieve hole 23 and preventing the liquid on the tower plate 2 from directly flowing down from the sieve hole 23. When the gas phase flow rate is large during operation, the float 3 is lifted up higher, so that the gas phase can pass smoothly and can fully contact with the liquid phase on the tower plate 2. In addition, due to the multiple grooves 31 on the peripheral wall of the float 3, the float 3 can be automatically pushed to roll when the material flows, thereby reducing the accumulation, crystallization or coking of materials on the surface of the float 3.

[0035] The multiple elastic arc plates 4 are fixed on the upper side of the sieve hole 23 in a centrally symmetrical manner, and the diameter of the open end formed at the upper end is smaller than the diameter of the float 3. This does not hinder the normal up and down floating of the float 3 to achieve a function similar to a float valve to separate materials, but can also play a certain diversion and buffering role on the material during the flow of the material, avoiding the accumulation of impurities in one place. Moreover, due to the continuous contact between the float 3 and the elastic arc plate 4, the elastic arc plate 4 can continuously vibrate during the rolling process of the float 3, reducing the possibility of scaling of the elastic arc plate 4.

[0036] In addition, when the float 3 rises to contact the floating bead 41, the floating bead 41 can reduce the friction between the two, so that the float 3 can roll more smoothly when the gas phase flow rate changes, and the cooperation between the floating bead 41 and the groove 31 can drive each elastic arc plate 4 to continuously strengthen the vibration of the rolling of the float 3, further reducing the possibility of impurities adhering to and accumulating on the surface of the float 3 or the elastic arc plate 4 due to factors such as friction, thereby better reducing the probability of blockage of the tower plate 2 and ensuring the stable operation of the distillation tower.

[0037] Furthermore, the circumferential surface of the float 3 is formed with a plurality of convex points (not shown in the figure). When the material flows through the float 3, the convex points can further disrupt the flow state of the material, preventing the material from stably adhering to the surface of the float 3 to form crystals or coking. At the same time, it can also disperse the material to a certain extent, reducing the accumulation of impurities in the float 3 and the surrounding area. In addition, the elastic arc plate 4 in contact with the float 3 has a greater vibration, which can further reduce the probability of blockage of the tower plate 2 and ensure the separation effect and normal operation of the distillation tower.

[0038] Reference Figure 4 Furthermore, in one implementation of the present embodiment, an auxiliary ball 5 may be provided between the elastic arc plate 4 and the float 3, and the diameter of the auxiliary ball 5 is smaller than the gap between the elastic arc plate 4 and the peripheral wall of the float 3. The auxiliary ball 5 may be made of the same material as the float 3, and the auxiliary ball 5 may be in the same shape as the float 3. When the gas phase velocity increases, the auxiliary ball 5 will float up and down with the airflow, which helps to further disperse the material and reduce the local pressure concentration phenomenon, thereby avoiding excessive accumulation of materials in a specific area and causing blockage. At the same time, the auxiliary ball 5 can also continuously collide with the float 3 when the float 3 rises, increase the vibration of the float 3, and increase the surface friction between the float 3 and the auxiliary ball 5, reduce the precipitation and accumulation of impurities on the peripheral wall of the float 3, and thus reduce the possibility of blockage of the tower plate 2.

[0039] Reference Figure 5 Furthermore, a shaping ring 42 is fixed to the open ends of the plurality of elastic arc plates 4. The shaping ring 42 is arranged to be fixed to the open ends of the plurality of elastic arc plates 4, so that the upper ends of the elastic arc plates 4 can be stabilized, so that the elastic arc plates 4 can still maintain a relatively stable shape and position under the impact of materials and the action of the floating ball 3 for a long time, and prevent the elastic arc plates 4 from being deformed, displaced, etc., which affect the coordination with the floating ball 3 and the diversion of materials, etc., and help maintain the effectiveness of the entire anti-blocking structure and reduce the occurrence of blockage of the tower plate 2. At the same time, the existence of the shaping ring 42 can also effectively guide the uniform distribution of the gas phase and the liquid phase, and avoid the occurrence of local overload, so as to better ensure the stability and efficiency of the distillation process.

[0040] The implementation principle of a distillation tower with an anti-clogging structure in the embodiment of the present application is: The float 3 is placed on the upper side of the sieve hole 23 and its diameter is larger than that of the sieve hole 23. The float 3 can fall on the upper side of the sieve hole 23 under normal conditions, thereby closing the sieve hole 23 and preventing the liquid on the tower plate 2 from flowing directly down from the sieve hole 23. When the gas phase flow rate is large during operation, the float 3 is lifted up higher, so that the gas phase can pass smoothly and fully contact with the liquid phase on the tower plate 2. In addition, due to the concave grooves 31 on the peripheral wall of the float 3, the float 3 can automatically promote the floating and rolling when the material flows, thereby reducing the accumulation, crystallization or coking of the material on the surface of the float 3. The elastic arc plate 4 is fixed on the upper side of the sieve hole 23 in a centrally symmetrical manner, and the diameter of the open end formed on the upper end is smaller than the diameter of the float 3. It does not hinder the normal up and down floating of the float 3 to realize the function similar to that of a float valve for material separation, and can also play a certain diversion and buffering role on the material during the flow of the material, thereby avoiding the accumulation of impurities in one place. Moreover, due to the cooperation between the float 3 and the elastic arc plate 4, the elastic arc plate 4 can continuously vibrate during the rolling process of the float 3, thereby effectively reducing the probability of blockage of the tower plate 2 and ensuring that the tower plate 2 can maintain a good working condition during long-term use.

[0041] Example 2 Reference Figure 6 , a distillation tower with an anti-clogging structure, compared with Example 1, the difference of this embodiment is: A clamping ring 6 is fixed at the root of the multiple elastic arc plates 4 on each sieve hole 23, and the clamping ring 6 includes a horizontal ring 61, an insert ring 62 and an elastic clamping plate 63. The outer diameter of the horizontal ring 61 is larger than the diameter of the sieve hole 23, and the roots of the multiple elastic arc plates 4 are fixed to the horizontal ring 61, the outer diameter of the insert ring 62 is the same as the diameter of the sieve hole 23, and the insert ring 62 is coaxially integrally formed on the lower side of the horizontal ring 61 for insertion into the sieve hole 23, and the multiple elastic clamping plates 63 are centrally symmetrically formed on the lower side of the insert ring 62, and the outer ends of each elastic clamping plate 63 tend to extend away from the axis direction of the insert ring 62 to form an outward expansion structure. After the clamping ring 6 is clamped in the sieve hole 23, the insert ring 62 is inserted in the sieve hole 23, the horizontal ring 61 abuts against the upper side of the tower plate 2, and the elastic clamping plate 63 abuts against the lower side of the tower plate 2, thereby limiting the clamping ring 6 from being separated from the sieve hole 23.

[0042] The clamping ring 6 is connected to the roots of multiple elastic arc plates 4 and is clamped and fixed in the sieve hole 23. The clamping method of the clamping ring 6 is convenient for subsequent disassembly and maintenance, reducing maintenance costs and time, and facilitating timely replacement of the elastic arc plates 4 and the float 3 after they are damaged.

[0043] Furthermore, the elastic card plate 63 is a unidirectional heat expansion plate, that is, the elastic card plate 63 is formed by laminating two metal plates with different thermal expansion coefficients, so that after the elastic card plate 63 expands due to heat, the outer end of the elastic card plate 63 can bend upward to press against the lower side of the tower plate 2.

[0044] In this way, the elastic clamp plate 63 is used as a unidirectional thermal expansion plate. During the operation of the distillation tower, as the temperature inside the tower body 1 increases, the outer end of the elastic clamp plate 63 can bend upward and press against the lower side of the tower plate 2, thereby ensuring that the clamp ring 6 is firmly fixed in the sieve hole 23 to prevent loosening due to vibration or other external factors. This not only improves the overall stability of the device, but also enhances the reliability of the anti-blocking structure, and further reduces the probability of blockage of the tower plate 2.

[0045] Compared with Example 1, the clamping ring 6 is connected to the roots of multiple elastic arc plates 4 and is clamped and fixed in the sieve hole 23. The clamping method of the clamping ring 6 facilitates subsequent disassembly and maintenance, reduces maintenance costs and time, and facilitates timely replacement of the elastic arc plates 4 and the float 3 after damage.

[0046] Example 3 Reference Figure 7 , a distillation tower with an anti-clogging structure, compared with Example 2, the difference of this embodiment is: A connecting ring 43 is fixed to the root of the plurality of elastic arc plates 4 , and the connecting ring 43 is coaxially rotatably connected to the clamping ring 6 .

[0047] Reference Figure 8 Each elastic arc plate 4 is also arranged to be inclined to the axis of the sieve hole 23, and an inclined flow channel is formed between adjacent elastic arc plates 4.

[0048] Compared with Example 2, the advantages of this embodiment are: a connecting ring 43 is fixed at the root of the multiple elastic arc plates 4 and the connecting ring 43 is coaxially rotatably connected to the clamping ring 6, so that the elastic arc plates 4 can flexibly rotate relative to the clamping ring 6. When the float 3 generates forces in different directions acting on the elastic arc plates 4 under conditions such as material impact, the elastic arc plates 4 can adaptively rotate to adjust the angle, better buffer and disperse these forces, and avoid damage to the elastic arc plates 4 or other components due to uneven force and abnormal material accumulation.

[0049] Reference Figure 8 The elastic arc plate 4 is inclined to the axis of the sieve hole 23, and an inclined flow channel is formed between adjacent elastic arc plates 4. This design helps to guide the gas phase and the liquid phase to be more evenly distributed on the entire tower plate 2, reduce the overload phenomenon in the local area, further improve the material separation effect, and effectively prevent impurities from accumulating in a large amount at a specific location, reduce the risk of blockage, and maintain the distillation tower in good working condition.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
