Description

Technical Field

[0001] This application relates to the technical field of gluconate production equipment, and more specifically, to a co-catalytic production equipment and method for calcium gluconate. Background Technology

[0002] Calcium gluconate, as an organic calcium salt, has a wide range of applications, especially in the medical field. It can be used to prevent and treat calcium deficiency diseases such as osteoporosis, tetany, osteomalacia, rickets, and for calcium supplementation in children, pregnant and lactating women, postmenopausal women, and the elderly. Currently, calcium gluconate is mainly produced through oxidation processes, including catalytic air oxidation, electrochemical oxidation, metal catalytic oxidation, chemical oxidation, bio-fermentation, and enzymatic methods. Most calcium gluconate manufacturers currently use bio-fermentation and enzymatic methods. Among these, the enzymatic process is currently the best method for calcium gluconate production due to its stable production process and relatively low production cost. For equipment using the enzymatic process to produce calcium gluconate, a circulating reaction method is often used to improve the efficiency of the catalytic oxidation reaction and ensure sufficient contact between the gluconate solution and air.

[0003] Current circulating reaction methods all aim to maximize the dispersion of the circulating liquid through spraying, allowing the solution to come into maximum contact with oxygen in the air and thus undergo catalytic oxidation, thereby improving the efficiency of the entire circulating reaction. However, they do not adequately consider how to efficiently utilize the oxygen in the air and how to reuse the oxygen generated during the reaction. As a result, current equipment relies on a strong air system to continuously refresh the air. Although this can continuously introduce air to maintain the reaction, it has little effect on increasing the oxygen content for catalytic oxidation, and it also fails to fully utilize the oxygen generated in the later stages of the reaction.

[0004] Therefore, designing a co-catalytic production equipment and method for calcium gluconate that can efficiently improve the contact effect between oxygen and solution while effectively utilizing the oxygen generated by the reaction itself for catalytic oxidation to improve oxygen utilization is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this application is to provide a co-catalytic production device for calcium gluconate. By installing a vacuum pump at the top of the reaction chamber, a partial low pressure is created at the top of the rotating reaction cylinder. This pressure causes air in the reaction chamber and newly generated oxygen from the lower part of the rotating cylinder to flow upwards from the bottom of the cylinder. This effectively replenishes the oxygen consumed in the catalytic oxidation reaction at the top of the cylinder, maintaining a stable oxygen supply. Furthermore, it introduces newly generated oxygen, increasing the oxygen concentration in the air and the probability of contact between oxygen and the solution, thus improving the contact effect and further increasing oxygen utilization and enhancing the catalytic oxidation effect. Additionally, since the air flow direction is opposite to the solution flow direction, the contact between air and solution is more direct and comprehensive, improving the contact effect between oxygen and solution and enhancing the catalytic oxidation effect. Simultaneously, the negative pressure at the top of the rotating reaction cylinder can slow down the solution flow rate and increase the gas flow rate, increasing the contact time between the solution and air and further enhancing the catalytic oxidation effect.

[0006] The purpose of this application is also to provide a method for the co-catalytic production of calcium gluconate. This method determines the flow rate of the calcium gluconate solution used for circulation in the co-catalytic equipment by using information on the desired calcium gluconate production yield. This allows for the determination of the ejector velocity and the rotational speed of the co-catalytic reaction. The determination of these two parameters directly affects the effective surface area and effective time for the gluconate solution to contact oxygen in the initial stage of circulation, providing an important foundation for sufficient contact between the calcium gluconate solution and oxygen during the circulation process to undergo a co-catalytic reaction. Simultaneously, based on the co-catalytic circulation flow rate information of calcium gluconate, the required amount of oxygen can be accurately determined, thereby precisely controlling the operation of the vacuum pump. This achieves efficient replenishment of the oxygen required for the co-catalytic reaction while fully and efficiently utilizing energy, further improving oxygen utilization efficiency.

[0007] In a first aspect, embodiments of this application provide a co-catalytic production apparatus for calcium gluconate, comprising a reaction chamber, a rotating reaction cylinder, a vacuum pump, a circulation guide pipe, an ejector pipe, a drive device, and a circulation pump; the rotating reaction cylinder is disposed in the reaction chamber, and one end of the rotating reaction cylinder near the bottom of the reaction chamber is rotatably connected to the drive device disposed at the bottom of the reaction chamber; the rotating reaction cylinder is rotatably connected to the top of the reaction chamber; a suction port is provided at the top of the reaction chamber, and the suction port communicates with the inner cavity of the rotating reaction cylinder; the vacuum pump is disposed on the reaction chamber, and the vacuum pump... It is connected to the air intake port; the flow inlet of the circulation guide pipe is located at the bottom of the reaction chamber and is connected to the reaction chamber; the flow outlet of the circulation guide pipe is connected to the inlet of the circulation pump; the ejector inlet of the ejector pipe is connected to the outlet of the circulation pump; the ejector outlet of the ejector pipe passes through the side wall of the reaction chamber and is set to correspond to the liquid inlet opened on the reaction rotating cylinder; the ejector outlet is close to the top of the reaction chamber; a gas guide port is opened on the side wall of the reaction chamber corresponding to the ejector outlet; a circulation reaction outlet is opened at one end of the reaction rotating cylinder near the bottom of the reaction chamber.

[0008] In this embodiment, the device uses a vacuum pump at the top of the reaction chamber to create a partial low pressure at the top of the rotating reaction cylinder. This pressure causes air in the reaction chamber and newly generated oxygen from the lower part of the rotating reaction cylinder to flow upwards from the bottom of the cylinder. This effectively replenishes the oxygen consumed in the catalytic oxidation reaction at the top of the cylinder, maintaining a stable oxygen supply. It also introduces newly generated oxygen, increasing the oxygen concentration in the air, increasing the probability of oxygen contact with the solution, improving the contact effect, and further increasing oxygen utilization, thus enhancing the catalytic oxidation effect. Furthermore, since the air flow direction is opposite to the solution flow direction, the contact between air and solution is more direct and comprehensive, improving the oxygen-solution contact effect and enhancing the catalytic oxidation effect. Simultaneously, the negative pressure at the top of the rotating reaction cylinder can slow down the solution flow rate and increase the gas flow rate, increasing the contact time between the solution and air, further enhancing the catalytic oxidation effect.

[0009] As one possible implementation, the rotating reaction cylinder includes an upper rotating cylinder, a transition rotating cylinder, a lower rotating cylinder, and a gas guiding assembly; the upper rotating cylinder is hollow to form an upper rotating reaction chamber; the transition rotating cylinder is hollow to form a transition rotating reaction chamber; the lower rotating cylinder is hollow to form a lower rotating reaction chamber; the upper rotating reaction chamber, the transition rotating reaction chamber, and the lower rotating reaction chamber are interconnected; the upper rotating reaction chamber is connected to an air intake port; the lower rotating reaction chamber is connected to a reaction chamber through a circulating reaction outlet; a rotating shaft is arranged along its axis in the lower rotating reaction chamber, and the rotating shaft is connected to the inner wall of the lower rotating cylinder through a guide plate arranged on the shaft wall; the rotating shaft extends to the bottom of the reaction chamber and is rotatably connected to a drive device; the gas guiding assembly is located in the transition rotating reaction chamber, and the support of the gas guiding assembly is connected to the inner wall of the transition rotating cylinder; liquid inlets are spaced apart on the side wall of the upper rotating cylinder near the top of the reaction chamber.

[0010] In this embodiment, if the reaction rotating cylinder is a simple cylindrical shape, the opposite flow directions of air and solution can improve the contact effect between the solution and oxygen in the air to some extent. To further improve the contact effect between oxygen in the air and the solution, a gas guiding component is provided in the transition rotating cylinder and a baffle is provided in the lower rotating cylinder to guide the airflow path, thereby further improving the contact effect between air and solution and increasing the efficiency of catalytic oxidation. At the same time, the baffle can also guide the solution to further mix and stir to some extent, improving the reaction effect of catalytic oxidation.

[0011] As one possible implementation, the diameter of the upper rotating reaction chamber is larger than the diameter of the lower rotating reaction chamber; the length of the upper rotating reaction chamber along its axis is greater than the length of the lower rotating reaction chamber along its axis.

[0012] In this embodiment, the upper rotating reaction chamber is understood to be the initial reaction chamber. On one hand, during the initial reaction, oxygen in the air is consumed and no new oxygen is generated for further catalytic oxidation. Therefore, a large amount of oxygen is needed to ensure the continuity of the reaction. The upper rotating reaction chamber has a larger radial dimension than the lower rotating reaction chamber, allowing it to hold more air and increase the oxygen content. Simultaneously, since the solution flows along the cylinder wall in the upper rotating reaction chamber, the larger cylinder wall area also increases, thereby increasing the effective contact area between the solution and oxygen and improving the efficiency of the catalytic oxidation reaction. On the other hand, the volume of the upper rotating reaction chamber is larger than that of the lower rotating reaction chamber, resulting in a relatively larger area of ​​negative pressure when the air pump draws air, thus enhancing the effect of the negative pressure. When air from the lower rotating reaction chamber rapidly enters the upper rotating reaction chamber due to air pressure, a certain pressure drop occurs due to the increased chamber volume. This pressure drop can reduce the air velocity to some extent, allowing the oxygen in the air to further and fully contact the solution, improving the catalytic oxidation effect. In addition, the length of the upper rotating reaction chamber is greater than that of the lower rotating reaction chamber, which increases the contact time between oxygen and solution in the upper rotating reaction chamber and improves the effect of catalytic oxidation reaction.

[0013] As one possible implementation, an ejector head is provided at one end of the ejector tube near the upper rotating cylinder, and the ejector outlet on the ejector head is adapted to the liquid inlet; the direction of the ejector outlet is tangent to the side wall of the upper rotating cylinder and inclined toward the transition rotating cylinder.

[0014] In this embodiment, if the solution is directly ejected from the ejector port along the axis of the upper rotating cylinder, the flow of the solution will be accelerated, thereby reducing the contact time between the solution and oxygen. The ejector port and inlet are tilted, allowing the solution to rotate and flow down the wall of the upper rotating cylinder. This increases the residence time of the solution in the upper rotating cylinder, improving the contact time between oxygen and the solution and enhancing the efficiency of the catalytic oxidation reaction. It also achieves a mixing and stirring effect for the liquid in the upper rotating reaction chamber.

[0015] As one possible implementation, the inlets are spaced apart around the axis of the upper rotating cylinder, and the spacing between adjacent inlets ensures that the fluid injected through the inlets does not cause interference in the radial direction of the upper rotating cylinder.

[0016] In this embodiment, the spacing between the inlets needs to ensure that the injected solutions do not interfere with each other in the radial direction, causing turbulence and disrupting the flow trajectory of the solution. This is to prevent the solution flow from being disturbed, which would prevent oxygen from fully contacting the solution for catalytic oxidation.

[0017] As one possible implementation, the gas guiding assembly includes a gas guiding baffle and a support body; the gas guiding baffle is located in the transition rotating reaction chamber; the support body is spaced apart around the axis of the transition rotating cylinder; one end of the support body is connected to the gas guiding baffle, and the other end is connected to the side wall of the transition rotating cylinder.

[0018] In this embodiment, the area in the upper rotating cylinder where the solution and oxygen are in full contact is mainly near the cavity wall of the upper rotating reaction chamber, while the middle area does not require excessive oxygen filling. The function of the gas guide baffle is to guide the oxygen introduced from the lower rotating cylinder along the cylinder wall of the upper rotating cylinder, increasing the contact effect between oxygen and the solution and improving oxygen utilization. Simultaneously, the presence of the gas guide baffle assists the vacuum pump in creating a vacuum above the baffle, achieving the effect of maintaining negative pressure.

[0019] As one possible implementation, the air guide baffle protrudes towards the side closer to the lower rotating cylinder to form a smooth air guide protrusion.

[0020] In this embodiment, the air guide baffle protrudes in a spherical shape, which improves the air guiding effect and does not reduce the kinetic energy of the air along the axis of the upper rotating cylinder due to the action of the air guide baffle, thus reducing the energy consumption of the air pump to a certain extent.

[0021] As one possible implementation, the guide plate extends in a bolt-like manner around the rotation axis from one end near the transitional rotating reaction chamber to one end of the circulating reaction outlet.

[0022] In this embodiment, the guide plate extends in a spiral shape, which guides the flow of the solution and increases the flow path, making the catalytic oxidation reaction more complete. It also guides the air, giving it rotational momentum after passing through the lower rotating cylinder, allowing it to adhere to the cylinder wall and thus improving the contact between oxygen and the solution.

[0023] As one possible implementation, the spiral direction of the guide plate is the same as the ejection direction of the ejector outlet.

[0024] In this embodiment, after the solution flows through the cylinder wall in the upper rotating cylinder, the solution surface has basically achieved effective contact with oxygen. The spiral direction of the guide plate is the same as the direction of the ejection outlet, which can ensure that the solution directly collides with the guide plate before entering the lower rotating cylinder to agitate the solution layer once. This allows the solution that was not in contact with oxygen before to complete contact with oxygen in the lower rotating cylinder, further improving the efficiency of the catalytic oxidation reaction.

[0025] Secondly, embodiments of this application provide a method for the co-catalytic production of calcium gluconate using the co-catalytic production equipment for calcium gluconate described in the first aspect, comprising: acquiring the yield information of calcium gluconate solution and determining the co-catalytic circulation flow rate data; determining the ejector speed and co-catalytic rotation speed based on the co-catalytic circulation flow rate data; determining the pumping parameters based on the co-catalytic circulation flow rate data; acquiring the ejector speed, co-catalytic rotation speed, and pumping parameters, and performing co-catalytic production.

[0026] In this embodiment, the method determines the flow rate of the calcium gluconate solution used for circulation in the co-catalytic device based on the production yield information of the calcium gluconate to be produced. This allows for the determination of the ejector rate and the rotational speed of the co-catalytic reaction. The determination of these two parameters directly affects the effective surface area and effective time for the gluconate solution to contact oxygen in the initial stage of circulation, providing an important foundation for sufficient contact between the calcium gluconate solution and oxygen during the circulation process to undergo a co-catalytic reaction. Simultaneously, based on the co-catalytic circulation flow rate information of calcium gluconate, the required amount of oxygen can be accurately determined, thereby precisely controlling the operation of the vacuum pump. This achieves effective replenishment of the oxygen required for the co-catalytic reaction while fully and efficiently utilizing energy, further improving the efficiency of oxygen utilization.

[0027] The beneficial effects of the calcium gluconate co-catalytic production equipment and method provided in this embodiment are as follows:

[0028] This device creates a partial low pressure at the top of the rotating reaction cylinder by installing a vacuum pump at the top of the reaction chamber. This pressure causes air in the reaction chamber, as well as newly generated oxygen from the lower part of the rotating cylinder, to flow upwards from the bottom of the cylinder. This effectively replenishes the oxygen consumed in the catalytic oxidation reaction at the top of the cylinder, maintaining a stable oxygen supply. It also introduces newly generated oxygen, increasing the oxygen concentration in the air, increasing the probability of oxygen contact with the solution, improving the contact effect, and further enhancing oxygen utilization and the catalytic oxidation effect. Furthermore, because the air flow direction is opposite to the solution flow direction, the contact between air and solution is more direct and comprehensive, improving the oxygen-solution contact effect and enhancing the catalytic oxidation reaction. Simultaneously, the negative pressure at the top of the rotating reaction cylinder can slow down the solution flow rate and increase the gas flow rate, increasing the contact time between the solution and air, further enhancing the catalytic oxidation effect.

[0029] This method determines the flow rate of the calcium gluconate solution used for circulation in the co-catalytic unit by using the production yield information of the calcium gluconate to be produced. This information is then used to determine the ejector rate and the rotation speed of the co-catalytic reaction. The determination of these two parameters directly affects the effective surface area and effective time for the gluconate solution to contact oxygen in the initial stage of circulation, providing an important foundation for sufficient contact between the calcium gluconate solution and oxygen during the circulation process to carry out the co-catalytic reaction. Simultaneously, based on the co-catalytic circulation flow rate information of calcium gluconate, the required amount of oxygen can be accurately determined, thereby precisely controlling the operation of the vacuum pump. This achieves efficient replenishment of the oxygen required for the co-catalytic reaction while fully and efficiently utilizing energy, further improving oxygen utilization efficiency.

Detailed Implementation

[0035] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0036] Calcium gluconate, as an organic calcium salt, has a wide range of applications, especially in the medical field. It can be used to prevent and treat calcium deficiency diseases such as osteoporosis, tetany, osteomalacia, rickets, and for calcium supplementation in children, pregnant and lactating women, postmenopausal women, and the elderly. Currently, calcium gluconate is mainly produced through oxidation processes, including catalytic air oxidation, electrochemical oxidation, metal catalysis, chemical oxidation, bio-fermentation, and enzymatic methods. Most calcium gluconate manufacturers currently use bio-fermentation and enzymatic methods. Among these, the enzymatic process is currently the best method for calcium gluconate production due to its stable production process and relatively low production cost. For equipment using the enzymatic process to produce calcium gluconate, a circulating reaction method is often used to improve the efficiency of the catalytic oxidation reaction and ensure sufficient contact between the gluconate solution and air.

[0037] Current circulating reaction methods all aim to maximize the dispersion of the circulating liquid through spraying, allowing the solution to come into maximum contact with oxygen in the air and thus undergo catalytic oxidation, thereby improving the efficiency of the entire circulating reaction. However, they do not adequately consider how to efficiently utilize the oxygen in the air and how to reuse the oxygen generated during the reaction. As a result, current equipment relies on a strong air system to continuously refresh the air. Although this can continuously introduce air to maintain the reaction, it has little effect on increasing the oxygen content for catalytic oxidation, and it also fails to fully utilize the oxygen generated in the later stages of the reaction.

[0038] refer to Figures 1-2This application provides a co-catalytic production apparatus for calcium gluconate. The apparatus includes a reaction chamber 01, a rotating reaction cylinder 02, a vacuum pump 03, a circulation guide pipe 04, an ejector pipe 05, a drive device 06, and a circulation pump 07. The rotating reaction cylinder 02 is disposed within the reaction chamber 01, and one end of the rotating reaction cylinder 02 near the bottom of the reaction chamber 01 is rotatably connected to the drive device 06 disposed at the bottom of the reaction chamber 01. The rotating reaction cylinder 02 is rotatably connected to the top of the reaction chamber 01. A suction port 12 is provided at the top of the reaction chamber 01, and the suction port 12 communicates with the inner cavity of the rotating reaction cylinder 02. The vacuum pump 03 is disposed on the reaction chamber 01, and the vacuum pump 03 is connected to the suction port 12. The inlet of the circulation guide pipe 04 is located at the bottom of the reaction chamber 01 and is connected to the reaction chamber 01; the outlet of the circulation guide pipe 04 is connected to the inlet of the circulation pump 07; the inlet of the ejector pipe 05 is connected to the outlet of the circulation pump 07; the outlet of the ejector pipe 05 passes through the side wall of the reaction chamber 01 and is set to correspond to the liquid inlet 212 opened on the reaction rotating cylinder 02; the outlet is close to the top of the reaction chamber 01; a gas guide port 11 is opened on the side wall of the reaction chamber 01 corresponding to the outlet; a circulation reaction outlet is opened at one end of the reaction rotating cylinder 02 near the bottom of the reaction chamber 01.

[0039] This device creates a partial low pressure at the top of the rotating reaction cylinder 02 by installing a vacuum pump 03 at the top of the reaction chamber 01. This pressure causes air in the reaction chamber 01 and newly generated oxygen from the lower part of the rotating reaction cylinder 02 to flow upwards from the bottom of the rotating reaction cylinder 02. This effectively replenishes the oxygen consumed in the catalytic oxidation reaction at the top of the rotating reaction cylinder 02, maintaining a stable oxygen supply. It also introduces newly generated oxygen, increasing the oxygen concentration in the air, increasing the probability of oxygen contact with the solution, improving the contact effect, and further increasing oxygen utilization, thus enhancing the catalytic oxidation effect. Furthermore, since the air flow direction is opposite to the solution flow direction, the contact between air and solution is in an opposing state, making the contact more direct and comprehensive, improving the oxygen-solution contact effect, and enhancing the catalytic oxidation effect. Simultaneously, the negative pressure at the top of the rotating reaction cylinder 02 can slow down the solution flow rate and increase the gas flow rate, increasing the contact time between the solution and air, further enhancing the catalytic oxidation effect.

[0040] Specifically, the rotating reaction cylinder 02 includes an upper rotating cylinder 21, a transition rotating cylinder 22, a lower rotating cylinder 23, and a gas guiding assembly 24; the upper rotating cylinder 21 is hollow to form an upper rotating reaction chamber 211; the transition rotating cylinder 22 is hollow to form a transition rotating reaction chamber 221; the lower rotating cylinder 23 is hollow to form a lower rotating reaction chamber 233; the upper rotating reaction chamber 211, the transition rotating reaction chamber 221, and the lower rotating reaction chamber 233 are interconnected; the upper rotating reaction chamber 211 is connected to the air intake 12; the lower rotating reaction chamber 233 undergoes a cyclic reaction. The outlet is connected to the reaction chamber 01; a rotating shaft 231 is arranged along its axis in the lower rotating reaction chamber 233, and the rotating shaft 231 is connected to the inner wall of the lower rotating cylinder 23 through a guide plate 232 arranged on the shaft wall; the rotating shaft 231 extends to the bottom of the reaction chamber 01 and is rotatably connected to the drive device 06; the gas guiding assembly 24 is located in the transition rotating reaction chamber 221, and the support body 241 of the gas guiding assembly 24 is connected to the inner wall of the transition rotating cylinder 22; liquid inlets 212 are spaced apart on the side wall of the upper rotating cylinder 21 near the top of the reaction chamber 01.

[0041] Since the air and solution flow in opposite directions, the contact effect between the solution and oxygen in the air can be improved to some extent. To further improve the contact effect between oxygen in the air and the solution, a gas guiding component 24 is installed in the transition rotating cylinder 22 and a baffle plate 232 is installed in the lower rotating cylinder 23 to guide the air flow path, thereby further improving the contact effect between air and solution and increasing the efficiency of catalytic oxidation. At the same time, the baffle plate 232 can also guide the solution to further mix and stir to some extent, improving the reaction effect of catalytic oxidation. In addition, since the air is guided in the opposite direction to the solution flow, it can also carry the oxygen generated in the later stage of the catalytic oxidation reaction, increasing the oxygen content while avoiding the use of strong air intake equipment to increase the oxygen concentration, thus achieving energy-saving and high-efficiency effects to a certain extent.

[0042] For each rotating cylinder, the diameter of the upper rotating reaction chamber 211 is larger than the diameter of the lower rotating reaction chamber 233; the length of the upper rotating reaction chamber 211 along its axis is also greater than the length of the lower rotating reaction chamber 233 along its axis. It can be understood that the upper rotating reaction chamber 211 is the initial reaction chamber. On the one hand, during the initial reaction, oxygen in the air is consumed and no new oxygen is generated for further catalytic oxidation. Therefore, a large amount of oxygen is needed to ensure the continuity of the reaction. The upper rotating reaction chamber 211 has a larger radial dimension than the lower rotating reaction chamber 233, allowing it to hold more air and increase the oxygen content. Simultaneously, since the solution in the upper rotating reaction chamber 211 flows along the rotating cylinder wall, the larger cylinder wall area also increases accordingly, thereby increasing the effective contact area between the solution and oxygen and improving the efficiency of the catalytic oxidation reaction. On the other hand, the volume of the upper rotating reaction chamber 211 is larger than that of the lower rotating reaction chamber 233. This results in a relatively larger area of ​​negative pressure formation when the vacuum pump 03 draws air, thus enhancing the effect of the negative pressure. Furthermore, when air from the lower rotating reaction chamber 233 rapidly enters the upper rotating reaction chamber 211 due to pressure, the increased chamber volume causes a certain pressure drop. This pressure drop reduces the air velocity to some extent, allowing oxygen in the air to have more sufficient contact with the solution, thereby improving the catalytic oxidation effect. Additionally, the length of the upper rotating reaction chamber 211 is greater than that of the lower rotating reaction chamber 233, which increases the contact time between oxygen and the solution in the upper rotating reaction chamber 211, further improving the catalytic oxidation reaction.

[0043] An ejector head 51 is provided at one end of the ejector tube 05 near the upper rotating cylinder 21, and the ejector outlet on the ejector head 51 is adapted to the liquid inlet 212; the direction of the ejector outlet is tangential to the side wall of the upper rotating cylinder 21 and inclined towards the transition rotating cylinder 22. If the solution is directly ejected from the ejector outlet along the axis of the upper rotating cylinder 21, the flow of the solution will be accelerated, thereby reducing the contact time between the solution and oxygen. The inclined arrangement of the ejector outlet and the liquid inlet 212 allows the solution to rotate and flow down the cylinder wall of the upper rotating cylinder 21, which not only increases the residence time of the solution in the upper rotating cylinder 21, thereby increasing the contact time between oxygen and the solution and improving the efficiency of the catalytic oxidation reaction, but also achieves the effect of mixing and stirring the liquid in the upper rotating reaction chamber 211.

[0044] Furthermore, the inlets 212 are spaced apart around the axis of the upper rotating cylinder 21, and the spacing between adjacent inlets 212 ensures that the fluid injected through the inlets 212 does not cause interference in the radial direction of the upper rotating cylinder 21. The spacing between the inlets 212 needs to ensure that the injected solutions do not interfere with each other in the radial direction, causing turbulence and disrupting the flow trajectory of the solution, thus avoiding a situation where the solution flow is disturbed and oxygen cannot fully contact the solution to carry out the catalytic oxidation reaction.

[0045] The gas guiding assembly 24 includes a gas guiding baffle 242 and a support body 241. The gas guiding baffle 242 is located in the transition rotating reaction chamber 221. The support body 241 is spaced apart around the axis of the transition rotating cylinder 22. One end of the support body 241 is connected to the gas guiding baffle 242, and the other end is connected to the side wall of the transition rotating cylinder 22. The area in the upper rotating cylinder 21 where the solution and oxygen are in full contact is mainly near the cavity wall of the upper rotating reaction chamber 211, while the middle area does not require much oxygen to fill. The function of the gas guiding baffle 242 is to guide the oxygen introduced from the lower rotating cylinder 23 to flow along the cylinder wall of the upper rotating cylinder 21, increasing the contact effect between oxygen and solution and improving oxygen utilization. At the same time, due to the presence of the gas guiding baffle 242, the vacuum pump 03 can assist in forming a vacuum above the gas guiding baffle 242 to maintain negative pressure.

[0046] Preferably, the air guide baffle 242 protrudes towards the side near the lower rotating cylinder 23 to form a smooth air guide protrusion. The protrusion of the air guide baffle 242 is spherical, which improves the air guiding effect and does not reduce the kinetic energy of the air along the axis of the upper rotating cylinder 21 due to the action of the air guide baffle 242, thus reducing the energy consumption of the air pump 03 to a certain extent.

[0047] The guide plate 232 extends in a bolt-like manner around the rotating shaft 231 from one end near the transition rotating reaction chamber 221 to one end of the circulating reaction outlet. The spiral extension of the guide plate 232 guides the solution flow and increases the flow path, thus making the catalytic oxidation reaction more complete. It also guides the air, giving it rotational momentum after passing through the lower rotating cylinder 23, allowing it to adhere to the cylinder wall and improve the contact between oxygen and the solution.

[0048] It is worth noting that the spiral direction of the guide plate 232 is the same as the ejection direction of the ejector outlet. In this way, after the solution flows through the cylinder wall in the upper rotating cylinder 21, the solution surface has basically achieved effective contact with oxygen. The fact that the spiral direction of the guide plate 232 is the same as the ejection direction of the ejector outlet ensures that the solution directly collides with the guide plate 232 before entering the lower rotating cylinder 23, causing a stirring of the solution layer. This allows the solution that was not in contact with oxygen before to complete contact with oxygen in the lower rotating cylinder 23, further improving the efficiency of the catalytic oxidation reaction.

[0049] In addition, the device includes a stirring fan; the stirring fan is spaced apart around the axis of the rotating shaft 231 and is located between the lower rotating cylinder 23 and the bottom of the reaction chamber 01. The stirring fan can stir and mix the solution at the bottom of the reaction chamber 01, thereby achieving uniform mixing of the solution and releasing the generated oxygen from the solution, preparing for the cyclic catalytic oxidation reaction.

[0050] This application also provides a method for the co-catalytic production of calcium gluconate, the method comprising the following steps:

[0051] Obtain the production information of calcium gluconate solution and determine the co-catalytic circulation flow rate data;

[0052] Based on the co-catalytic circulation flow rate data, the ejector velocity and co-catalytic rotation speed are determined;

[0053] Determine the pumping parameters based on the co-catalytic circulation flow rate data;

[0054] The ejection velocity, co-catalytic rotation speed, and pumping parameters are obtained to carry out co-catalytic production.

[0055] This method determines the flow rate of the calcium gluconate solution used for circulation in the co-catalytic unit by using the production yield information of the calcium gluconate to be produced. This information is then used to determine the ejector rate and the rotation speed of the co-catalytic reaction. The determination of these two parameters directly affects the effective surface area and effective time for the gluconate solution to contact oxygen in the initial stage of circulation, providing an important foundation for sufficient contact between the calcium gluconate solution and oxygen during the circulation process to carry out the co-catalytic reaction. Simultaneously, based on the co-catalytic circulation flow rate information of calcium gluconate, the required amount of oxygen can be accurately determined, thereby precisely controlling the operation of the vacuum pump. This achieves efficient replenishment of the oxygen required for the co-catalytic reaction while fully and efficiently utilizing energy, further improving oxygen utilization efficiency.

[0056] In summary, the beneficial effects of the calcium gluconate co-catalytic production equipment and method provided in this application are as follows:

[0057] This device creates a partial low pressure at the top of the rotating reaction cylinder 02 by installing a vacuum pump 03 at the top of the reaction chamber 01. This pressure causes air in the reaction chamber 01 and newly generated oxygen from the lower part of the rotating reaction cylinder 02 to flow upwards from the bottom of the rotating reaction cylinder 02. This effectively replenishes the oxygen consumed in the catalytic oxidation reaction at the top of the rotating reaction cylinder 02, maintaining a stable oxygen supply. It also introduces newly generated oxygen, increasing the oxygen concentration in the air, increasing the probability of oxygen contact with the solution, improving the contact effect, and further increasing oxygen utilization, thus enhancing the catalytic oxidation effect. Furthermore, since the air flow direction is opposite to the solution flow direction, the contact between air and solution is in an opposing state, making the contact more direct and comprehensive, improving the oxygen-solution contact effect, and enhancing the catalytic oxidation effect. Simultaneously, the negative pressure at the top of the rotating reaction cylinder 02 can slow down the solution flow rate and increase the gas flow rate, increasing the contact time between the solution and air, further enhancing the catalytic oxidation effect.

[0058] To further improve the contact between oxygen in the air and the solution, a gas guiding component is installed in the transition rotating cylinder, and a baffle is installed in the lower rotating cylinder to guide the airflow path. This further enhances the contact between air and solution, thereby increasing the efficiency of catalytic oxidation. Simultaneously, the baffle also guides the solution to a certain extent for further mixing and stirring, improving the reaction effect of catalytic oxidation.

[0059] The upper rotating reaction chamber is the initial reaction chamber. In the initial reaction, oxygen in the air is consumed and no new oxygen is generated for further catalytic oxidation. Therefore, a large supply of oxygen is needed to ensure the continuity of the reaction. The upper rotating reaction chamber has a larger radial dimension than the lower rotating reaction chamber, allowing it to hold more air and increasing the oxygen content. Simultaneously, since the solution flows along the cylinder wall in the upper rotating reaction chamber, the larger chamber wall area also increases, further increasing the effective contact area between the solution and oxygen, thus improving the efficiency of the catalytic oxidation reaction. Furthermore, the larger volume of the upper rotating reaction chamber allows for a larger negative pressure area during air extraction, enhancing the negative pressure effect. When air from the lower rotating reaction chamber rapidly enters the upper rotating reaction chamber due to air pressure, the increased chamber volume creates a pressure drop, which reduces the air velocity to some extent, allowing the oxygen in the air to further and fully contact the solution, improving the catalytic oxidation effect. In addition, the length of the upper rotating reaction chamber is greater than that of the lower rotating reaction chamber, which increases the contact time between oxygen and solution in the upper rotating reaction chamber and improves the effect of catalytic oxidation reaction.

[0060] The inclined ejector outlet and liquid inlet allow the solution to rotate and flow down the wall of the upper rotating cylinder. This increases the residence time of the solution in the upper rotating cylinder, improves the contact time between oxygen and the solution, enhances the efficiency of the catalytic oxidation reaction, and also achieves the effect of mixing and stirring the liquid in the upper rotating reaction chamber.

[0061] The spacing between the inlets needs to ensure that the solutions injected do not interfere with each other in the radial direction, causing turbulence and disrupting the flow trajectory of the solution. This is to prevent the solution flow from being disturbed, which would prevent oxygen from fully contacting the solution for catalytic oxidation.

[0062] The area in the upper rotating cylinder where the solution and oxygen come into full contact is mainly near the wall of the upper rotating reaction chamber. The middle area does not require much oxygen. The function of the gas guide baffle is to guide the oxygen introduced from the lower rotating cylinder along the wall of the upper rotating cylinder, increasing the contact effect between oxygen and the solution and improving oxygen utilization. At the same time, the presence of the gas guide baffle helps the vacuum pump to create a vacuum above the gas guide baffle, achieving the effect of maintaining negative pressure.

[0063] The guide vanes extend in a spiral shape, guiding the solution flow and increasing its path, thus ensuring a more complete catalytic oxidation reaction. They also guide air, giving it rotational momentum as it passes through the rotating cylinder, allowing it to adhere to the cylinder wall and further enhancing the contact between oxygen and the solution.

[0064] In the upper rotating cylinder, after the solution flows through the cylinder wall, the solution surface has basically achieved effective contact with oxygen. The spiral direction of the guide plate is the same as the direction of the ejection outlet, which ensures that the solution directly collides with the guide plate before entering the lower rotating cylinder to agitate the solution layer. This allows the solution that was not in contact with oxygen before to complete contact with oxygen in the lower rotating cylinder, further improving the efficiency of the catalytic oxidation reaction.

[0065] This method determines the flow rate of the calcium gluconate solution used for circulation in the co-catalytic unit by using the production yield information of the calcium gluconate to be produced. This information is then used to determine the ejector rate and the rotation speed of the co-catalytic reaction. The determination of these two parameters directly affects the effective surface area and effective time for the gluconate solution to contact oxygen in the initial stage of circulation, providing an important foundation for sufficient contact between the calcium gluconate solution and oxygen during the circulation process to carry out the co-catalytic reaction. Simultaneously, based on the co-catalytic circulation flow rate information of calcium gluconate, the required amount of oxygen can be accurately determined, thereby precisely controlling the operation of the vacuum pump. This achieves efficient replenishment of the oxygen required for the co-catalytic reaction while fully and efficiently utilizing energy, further improving oxygen utilization efficiency.
