Description

Technical Field

[0001] This application relates to the technical field of gluconate production equipment, and more specifically, to a device and method for treating gluconate solution with activated carbon. Background Technology

[0002] Gluconate has a wide range of applications, being a polyhydroxy acid salt widely used in medicine, food, chemical industry, light industry, and agriculture. There are various types of gluconate, each with different physicochemical properties, and their selection and effects vary depending on the application. Currently, gluconate production is on a large scale, greatly meeting the needs of social life and production, and providing an important material foundation for social production and development. Gluconate is mainly produced by mixing glucose and calcium carbonate, adding glucose peroxidase and catalase, and then oxidizing at 37 degrees Celsius to directly obtain calcium gluconate. This traditional method suffers from low labor productivity, high energy consumption, and unstable product quality.

[0003] There are various methods for producing gluconate, mainly including catalytic air oxidation, electrochemical oxidation, metal catalysis, chemical oxidation, bio-fermentation, and enzymatic methods. The resulting gluconate stock solution after oxidation needs to undergo neutralization, decolorization, concentration, annealing, centrifugation, and drying to form pure gluconate for use. Decolorization is an indispensable step in gluconate production, primarily adsorbing pigments and small molecules present in the solution. Currently, activated carbon decolorization is the main method. During activated carbon decolorization, it is crucial to ensure that the activated carbon is sufficiently and uniformly dispersed in the solution to achieve efficient decolorization. Most current decolorization equipment simply calculates the required amount of activated carbon and then continuously feeds the solution and activated carbon into a mixer while maintaining the temperature. This method cannot completely guarantee the uniform and thorough mixing of activated carbon in the solution, especially during continuous production where the flow rate of the solution changes due to adjustments in output. Simply pouring the solution and activated carbon into the mixer cannot guarantee the activated carbon content per unit volume or the uniform distribution of activated carbon in the solution.

[0004] Therefore, designing an activated carbon treatment device and method for gluconate solution that can adjust the activated carbon mixing ratio in real time according to the gluconate flow rate to ensure uniform mixing of activated carbon in gluconate solution and improve decolorization effect is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this application embodiment is also to provide a method for treating gluconate solution with activated carbon. This method first determines the required amount of activated carbon based on production information, and then obtains the relationship between the addition pressure and the leakage value of activated carbon from the addition mechanism under pressure based on the equipment design data. Furthermore, it determines the actual amount of activated carbon to be added based on the real-time detected flow rate of the gluconate solution, and determines the gas pressure by referring to the relationship between the activated carbon leakage value and the addition gas pressure. This ensures accurate adjustment of the addition gas pressure, guaranteeing that the amount of activated carbon added meets the decolorization requirements of the gluconate solution in real time. Simultaneously, the determination of the activated carbon addition amount can be automatically adjusted in real time, achieving automated operation while ensuring the decolorization effect, greatly improving the efficiency of the decolorization process.

[0006] The purpose of this application is to provide an activated carbon treatment device for gluconate solution. By placing an activated carbon adding mechanism in the airflow chamber and adjusting the amount of activated carbon added per unit time based on real-time detection of the flow rate of the gluconate solution in the liquid flow chamber, this effectively avoids the uneven activated carbon content per unit volume caused by adding activated carbon at a constant flow rate without considering the flow rate of the gluconate solution. This, in turn, leads to insufficient decolorization and reduces the decolorization effect of the decolorization process. Furthermore, because the activated carbon addition amount can be adjusted in real time, it can achieve efficient and comprehensive utilization of activated carbon to a certain extent. In decolorization processes using large amounts of activated carbon, this effectively reduces waste and helps to reduce costs.

[0007] In a first aspect, embodiments of this application provide a method for treating gluconate solution with activated carbon, which employs the gluconate solution activated carbon treatment device described in the first aspect, comprising: acquiring activated carbon addition amount and initial flow rate data based on production information; adding activated carbon according to the activated carbon addition amount; determining the initial addition gas pressure based on the initial flow rate data; acquiring measured flow rate data, establishing a unit addition amount analysis model and determining the actual addition gas pressure; and adjusting the addition gas pressure based on the actual addition gas pressure.

[0008] In this embodiment, the method first determines the required amount of activated carbon based on production information, and then obtains the relationship between the addition pressure and the leakage value of activated carbon from the addition mechanism under pressure based on the equipment design data. Next, it determines the actual amount of activated carbon to be added based on the real-time detected flow rate of the gluconate solution, and determines the gas pressure by referring to the relationship between the activated carbon leakage value and the addition gas pressure. This ensures accurate adjustment of the addition gas pressure, guaranteeing that the amount of activated carbon added meets the decolorization requirements of the gluconate solution in real time. Simultaneously, the determination of the activated carbon addition amount can be automatically adjusted in real time, achieving automated operation while ensuring the decolorization effect, greatly improving the efficiency of the decolorization process.

[0009] One possible approach involves acquiring measured flow rate data, establishing a unit addition analysis model, and determining the actual added gas pressure. This includes: obtaining a graph showing the relationship between added gas pressure and carbon discharge rate per unit time based on design data; obtaining the theoretical activated carbon decolorization amount U1 per unit volume of gluconate solution; acquiring measured flow rate data Q1 per unit time, and calculating the actual activated carbon decolorization amount Ux per unit time based on the theoretical activated carbon decolorization amount U1 per unit volume using the following formula: Ux = Q1 * U1; and determining the actual added gas pressure based on the actual activated carbon decolorization amount Ux per unit time, combined with the graph showing the relationship between added gas pressure and carbon discharge rate per unit time.

[0010] In the embodiments of this application, the determination of the actual added gas pressure mainly involves determining the amount of activated carbon added that needs to be adjusted according to the change in flow rate, and then determining the actual added gas pressure based on the established relationship between pressure and activated carbon addition amount.

[0011] As one possible implementation, obtaining the measured flow data Qa per unit time includes: collecting regional measured flow datasets {Q1,Q2,…,Qn} within each flow isolation zone; and determining the mean of the regional measured flow datasets as the measured flow data Qa.

[0012] In this embodiment, since the liquid flow chamber is isolated by multiple flow isolation walls, the flow rate in the flow isolation areas closer to the central axis gradually decreases due to pressure loss when the gluconate solution is injected into the liquid flow chamber. Therefore, in order to improve the overall flow rate measurement of the gluconate solution, combining the flow rate data measured in each flow isolation area can improve the accuracy of the activated carbon usage data.

[0013] Secondly, embodiments of this application provide an activated carbon treatment device for gluconate solution, including a mixing cylinder, a flow guide cover, a mixing and stirring chamber, and a mixing rotating body; the mixing cylinder is hollow to form a mixing chamber; a gas-liquid isolation cylinder wall is provided at one end of the mixing chamber near the top of the mixing cylinder; an airflow cavity is formed inside the gas-liquid isolation cylinder wall, and a liquid flow cavity is formed between the gas-liquid isolation cylinder wall and the cylinder wall of the mixing cylinder; flow isolation walls are spaced around the axis of the mixing cylinder in the liquid flow cavity, and the flow isolation walls are connected by a flow detection bracket; the flow guide cover is provided on the mixing cylinder; an activated carbon adding mechanism is formed on the flow guide cover at a position corresponding to the airflow cavity along the axis of the mixing cylinder; an airflow cavity is formed between the activated carbon adding mechanism and the gas-liquid isolation cylinder wall; the airflow cavity is connected to a first air filling pipe through the flow guide cover; the activated carbon adding mechanism is detachably connected to a second air filling pipe; the mixing and stirring chamber is provided at one end of the mixing cylinder away from the flow guide cover; the mixing rotating body is rotatably connected to the mixing and stirring chamber.

[0014] In this embodiment, the device places an activated carbon adding mechanism in the airflow chamber and adjusts the amount of activated carbon added per unit time based on real-time detection of the gluconate solution flow rate in the liquid flow chamber. This effectively avoids the uneven activated carbon content per unit volume caused by adding activated carbon at a constant flow rate without considering the gluconate solution flow rate, which would result in insufficient decolorization and reduced decolorization effect. Furthermore, the ability to adjust the activated carbon addition amount in real time allows for efficient and comprehensive utilization of activated carbon, effectively reducing waste in decolorization processes that use large amounts of activated carbon and thus reducing costs.

[0015] As one possible implementation, the activated carbon adding mechanism includes an activated carbon storage tube, an activated carbon adding head, a adding amount adjustment disc, and an elastomer; one end of the activated carbon storage tube is mounted on the guide cover and is detachably connected to the second air inlet tube; the other end of the activated carbon storage tube is connected to the activated carbon adding head; the activated carbon adding head has a hollow interior forming an adding cavity, and activated carbon discharge holes communicating with the adding cavity are spaced apart on the side wall of the activated carbon adding head; the adding amount adjustment disc is slidably mounted in the adding cavity; one end of the elastomer is connected to the activated carbon adding head, and the other end abuts against the adding amount adjustment disc.

[0016] In this embodiment, activated carbon is added by applying pressure to the activated carbon stored in the activated carbon storage tube and the adding chamber, forcing the activated carbon out through the activated carbon vent hole and being carried away by the airflow on the surface of the activated carbon adding head. It is understood that to ensure the activated carbon is carried away by the airflow after extrusion, the pressure applied in the activated carbon storage tube is greater than the gas pressure in the airflow chamber. Thus, the pressure difference between the inside and outside of the activated carbon vent hole generates an extrusion force, ensuring the activated carbon is smoothly extruded and carried away. The addition amount adjustment disc moves along the axis of the activated carbon storage tube according to the flow rate and the added pressure, opening and closing the vent hole, thereby adjusting the amount of activated carbon discharged in real time.

[0017] As one possible implementation, the cross-sectional diameter of the activated carbon feeding head in a direction perpendicular to the axis of the activated carbon storage tube gradually increases along the axis of the activated carbon storage tube.

[0018] In this embodiment, the amount of activated carbon added increases with the increase of flow rate. Considering that the activated carbon can be replenished in a timely manner, and that the activated carbon can be quickly mixed into the gluconate solution after being taken away from the activated carbon adding head, the activated carbon adding head is set into a cone-shaped structure. This ensures that the activated carbon generates a radial velocity when moving along the cone surface, and thus quickly mixes with the flowing gluconate solution to begin the decolorization process.

[0019] As one possible implementation, activated carbon vent holes are evenly spaced around the axis of the activated carbon storage tube, and the number of activated carbon vent holes in the direction around the axis of the activated carbon storage tube increases regularly along the axis of the activated carbon storage tube.

[0020] In the embodiments of this application, it can be understood that as the flow rate increases, the amount of activated carbon added will also increase, and the addition pressure will increase accordingly. In order to ensure that a wide range of activated carbon addition adjustments can be met on the relatively small structure of the activated carbon addition head, the number of activated carbon discharge holes is increased regularly along the axis of the activated carbon storage tube. This can increase the amount of activated carbon discharged and also determine the pattern of the discharge, ensuring that the accurate determination of the amount of activated carbon discharged can be completed smoothly.

[0021] As one possible implementation, an inclined surface adapted to the surface of the activated carbon adding head is formed on the end of the gas-liquid isolation cylinder wall near the activated carbon adding head, so that an activated carbon adding gap is formed between the gas-liquid isolation cylinder wall and the activated carbon adding head.

[0022] In this embodiment, a small gap is formed between the gas-liquid isolation cylinder wall and the activated carbon addition head. On the one hand, this ensures that the activated carbon flows out of the gap in a consistent direction, which facilitates the structural design of the mixing cylinder to ensure uniform mixing of the activated carbon and gluconate solution. On the other hand, due to the formation of the gap, the gas velocity in the gas flow chamber increases when passing through the gap, which enables the activated carbon to generate a greater radial velocity and mix quickly with the gluconate solution to carry out the decolorization effect as early as possible.

[0023] As one possible implementation, the side opening of the flow guide cover forms a liquid inlet; a spiral baffle is formed inside the flow guide cover, and the gap between the spiral baffles corresponds to the gap defined by each flow isolation wall in the liquid flow chamber.

[0024] In this embodiment, the main function of the flow guide cover is to adjust the flow rate of the gluconate solution. Without the flow guide cover, the gluconate solution, after entering the liquid flow chamber, will not flow in the predetermined order from the space isolated by the outer flow isolation wall to the space isolated by the innermost flow isolation wall. Instead, it will flow randomly through arbitrary flow gaps. This will make it impossible to accurately measure the flow rate of the gluconate solution. Furthermore, due to the random flow of the solution, it is impossible to achieve uniform mixing between the activated carbon and the solution to achieve a good decolorization effect.

[0025] As one possible implementation, the diameter of the mixing cylinder is larger than the diameter of the mixing chamber; one end of the mixing cylinder near the mixing chamber is connected to the mixing chamber via an inclined mixing wall.

[0026] In the embodiments of this application, it can be understood that the inclined mixing wall actually provides a platform for mixing gluconate solution and activated carbon. After the activated carbon and gluconate reach the inclined mixing wall, they will undergo an effective collision mixing, avoiding the situation where the activated carbon only contacts the surface of the solution, thus providing favorable conditions for uniform mixing. Therefore, the position of the inclined mixing wall also needs to be considered as the position where the activated carbon falls, and it is necessary to prevent the activated carbon from falling directly into the mixing chamber.

[0027] The beneficial effects of the gluconate solution activated carbon treatment device and method provided in this embodiment are as follows:

[0028] The activated carbon treatment device for gluconate solution utilizes an activated carbon addition mechanism placed in the airflow chamber. By adjusting the amount of activated carbon added per unit time based on real-time detection of the gluconate solution flow rate in the liquid flow chamber, it effectively avoids the uneven activated carbon content per unit volume caused by adding activated carbon at a constant flow rate without considering the gluconate solution flow rate. This prevents insufficient decolorization and reduces the decolorization effect. Furthermore, the ability to adjust the activated carbon addition amount in real-time allows for efficient and comprehensive utilization of activated carbon, effectively reducing waste in decolorization processes that use large amounts of activated carbon and thus mitigating costs.

[0029] The activated carbon treatment method for gluconate solution first determines the required amount of activated carbon based on production information. Then, based on equipment design data, it obtains the relationship between the addition pressure and the leakage value of activated carbon from the addition mechanism under pressure. Next, it determines the actual amount of activated carbon to be added based on the real-time detected flow rate of the gluconate solution. The gas pressure is then determined by referring to the relationship between the activated carbon leakage value and the addition pressure, ensuring accurate adjustment of the addition pressure and guaranteeing that the amount of activated carbon added meets the decolorization requirements of the gluconate solution in real time. Simultaneously, the determination of the activated carbon addition amount can be automatically adjusted in real time, achieving automated operation while ensuring decolorization effect, greatly improving the efficiency of the decolorization process.

[0036] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0037] Gluconate has a wide range of applications, being a polyhydroxy acid salt widely used in medicine, food, chemical industry, light industry, and agriculture. There are various types of gluconate, each with different physicochemical properties, and their selection and effects vary depending on the application. Currently, gluconate production is on a large scale, greatly meeting the needs of social life and production, and providing an important material foundation for social production and development. Gluconate is mainly produced by mixing glucose and calcium carbonate, adding glucose peroxidase and catalase, and then oxidizing at 37 degrees Celsius to directly obtain calcium gluconate. This traditional method suffers from low labor productivity, high energy consumption, and unstable product quality.

[0038] There are various methods for producing gluconate, mainly including catalytic air oxidation, electrochemical oxidation, metal catalysis, chemical oxidation, bio-fermentation, and enzymatic methods. The resulting gluconate stock solution after oxidation needs to undergo neutralization, decolorization, concentration, annealing, centrifugation, and drying to form pure gluconate for use. Decolorization is an indispensable step in gluconate production, primarily adsorbing pigments and small molecules present in the solution.

Simply pouring the solution and activated carbon into the mixer cannot guarantee the activated carbon content per unit volume or the uniform distribution of activated carbon in the solution.

[0039] refer to Figures 1-3 This application provides an activated carbon treatment device for gluconate solution. The device includes a mixing cylinder 01, a guide cover 02, a mixing and stirring chamber 03, and a mixing rotating body 04. The mixing cylinder 01 is hollow, forming a mixing chamber. A gas-liquid isolation wall 11 is provided at one end of the mixing chamber near the top of the mixing cylinder 01. An airflow chamber is formed inside the gas-liquid isolation wall 11, and a liquid flow chamber is formed between the gas-liquid isolation wall 11 and the wall of the mixing cylinder 01. Flow isolation walls 12 are spaced apart around the axis of the mixing cylinder 01 in the liquid flow chamber, and the flow isolation walls 12 are connected by a flow detection bracket. A flow cover 02 is disposed on the mixing cylinder 01; an activated carbon adding mechanism 24 is formed on the flow cover 02 at a position corresponding to the airflow cavity along the axis of the mixing cylinder 01; an airflow cavity is formed between the activated carbon adding mechanism 24 and the gas-liquid isolation cylinder wall 11; the airflow cavity is connected to the first air filling pipe 21 through the flow cover 02; the activated carbon adding mechanism 24 is detachably connected to the second air filling pipe 22; a mixing and stirring chamber 03 is disposed on the mixing cylinder 01 at one end away from the flow cover 02; a mixing rotating body 04 is rotatably connected to the mixing and stirring chamber 03.

[0040] This device, by placing an activated carbon adding mechanism 24 in the airflow chamber and adjusting the amount of activated carbon added per unit time based on real-time detection of the gluconate solution flow rate in the liquid flow chamber, effectively avoids the uneven activated carbon content per unit volume caused by adding activated carbon at a constant flow rate without considering the gluconate solution flow rate. This prevents insufficient decolorization and reduces the decolorization effect of the process. Furthermore, the ability to adjust the activated carbon addition amount in real-time allows for efficient and comprehensive utilization of activated carbon, effectively reducing waste in decolorization processes that use large amounts of activated carbon and thus helping to reduce costs.

[0041] The detailed structure of the device will be described below.

[0042] The activated carbon adding mechanism 24 includes an activated carbon storage tube 241, an activated carbon adding head 242, an adding amount adjustment disc 243, and an elastic body 244. One end of the activated carbon storage tube 241 is disposed on the guide cover 02 and is detachably connected to the second air inlet tube 22. The other end of the activated carbon storage tube 241 is connected to the activated carbon adding head 242. The activated carbon adding head 242 is hollow inside to form an adding cavity, and activated carbon discharge holes 2421 communicating with the adding cavity are spaced apart on the side wall of the activated carbon adding head 242. The adding amount adjustment disc 243 is slidably disposed in the adding cavity. One end of the elastic body 244 is connected to the activated carbon adding head 242, and the other end abuts against the adding amount adjustment disc 243.

[0043] Activated carbon is added by applying pressure to the activated carbon stored in the activated carbon storage tube 241 and the adding chamber, forcing the activated carbon out through the activated carbon vent hole 2421 and carried away by the airflow on the surface of the activated carbon adding head 242. It can be understood that to ensure the activated carbon is carried away by the airflow after extrusion, the pressure applied in the activated carbon storage tube 241 is greater than the gas pressure in the airflow chamber. Thus, the pressure difference between the inside and outside of the activated carbon vent hole 2421 generates an extrusion force, ensuring the activated carbon is smoothly extruded and carried away. The addition amount adjustment disc 243, acting on the addition pressure according to the flow rate, moves along the axis of the activated carbon storage tube 241, opening and closing the vent hole, thereby adjusting the amount of activated carbon discharged in real time.

[0044] Preferably, the cross-sectional diameter of the activated carbon addition head 242 in the direction perpendicular to the axis of the activated carbon storage tube 241 gradually increases along the axis of the activated carbon storage tube 241. The amount of activated carbon added will increase with the increase of the flow rate. Considering that the activated carbon can be replenished in a timely manner, and that the activated carbon can be quickly mixed into the gluconate solution after being taken off the activated carbon addition head 242, the activated carbon addition head 242 is set into a cone-shaped structure. This ensures that the activated carbon generates radial velocity when moving along the cone surface, and thus quickly mixes with the flowing gluconate solution to begin the decolorization process.

[0045] Furthermore, the activated carbon discharge holes 2421 are evenly spaced around the axis of the activated carbon storage tube 241, and the number of activated carbon discharge holes 2421 increases regularly along the axis of the activated carbon storage tube 241. It is understood that as the flow rate increases, the amount of activated carbon added also increases, and consequently, the addition pressure increases. To ensure a wide range of activated carbon addition adjustments within the relatively small structure of the activated carbon addition head 242, regularly increasing the number of activated carbon discharge holes 2421 along the axis of the activated carbon storage tube 241 improves the activated carbon discharge rate and also establishes a consistent discharge rate, ensuring accurate determination of the activated carbon discharge amount.

[0046] An inclined surface adapted to the surface of the activated carbon addition head 242 is formed at one end of the gas-liquid isolation cylinder wall 11 near the activated carbon addition head 242, creating an activated carbon addition gap between the gas-liquid isolation cylinder wall 11 and the activated carbon addition head 242. This small gap ensures that the activated carbon flows out in a consistent direction, facilitating the structural design of the mixing cylinder 01 to guarantee uniform mixing of the activated carbon and gluconate solution. Furthermore, the gap increases the gas velocity in the gas flow chamber as it passes through it, allowing the activated carbon to generate a greater radial velocity and mix rapidly with the gluconate solution for earlier decolorization.

[0047] The side opening of the flow guide cover 02 forms a liquid inlet; a spiral baffle 23 is formed inside the flow guide cover 02, and the gap between the spiral baffles 23 corresponds to the gap defined by each flow isolation wall 12 in the liquid flow chamber. The main function of the flow guide cover 02 is to adjust the flow rate of the gluconate solution. Without the guiding effect of the flow guide cover 02, the gluconate solution will not flow in the predetermined order from the space isolated by the outer flow isolation wall 12 to the space isolated by the innermost flow isolation wall 12 after entering the liquid flow chamber. Instead, it will flow randomly through arbitrary flow gaps. This will make it impossible to accurately measure the flow rate of the gluconate solution. At the same time, due to the random flow of the solution, it is impossible to achieve uniform mixing of activated carbon and solution to achieve a good decolorization effect.

[0048] The diameter of the mixing cylinder 01 is larger than the diameter of the mixing chamber 03. One end of the mixing cylinder 01, near the mixing chamber 03, is connected to the mixing chamber 03 via an inclined mixing wall. The inclined mixing wall provides a platform for mixing the gluconate solution and activated carbon. Upon reaching the inclined mixing wall, the activated carbon and gluconate undergo effective collision mixing, preventing the activated carbon from only contacting the surface of the solution and providing favorable conditions for uniform mixing. Therefore, the position of the inclined mixing wall also needs to be considered in relation to where the activated carbon falls, preventing it from falling directly into the mixing chamber 03.

[0049] In addition, the mixing chamber 03 is hollow, forming a stirring chamber; bolted stirring blades are installed in the stirring chamber and fixed to the inner wall of the mixing chamber 03. The activated carbon and gluconate solution are further mixed by swirling flow.

[0050] It should be noted that the decolorization effect of activated carbon has certain temperature requirements. The gas blown out of the first gas filling tube 21 can be heated to adjust the temperature when the activated carbon is mixed with the gluconate solution.

[0051] It is understandable that the number of flow isolation walls can be determined according to actual needs. Of course, the diameter of each flow isolation wall can also be determined based on actual conditions. Considering that the gluconate solution flows from the outside in, the flow velocity gradually decreases from the outside in within each flow isolation zone, thus causing changes in flow rate and requiring an adjustment in the amount of activated carbon. It can be appreciated that, compared to each flow isolation wall having a uniform height near the bottom of the mixing cylinder, designing the flow isolation walls to have different heights relative to the bottom of the mixing cylinder, gradually increasing from the center outwards, facilitates the guidance of solution flow. Furthermore, it allows the gluconate solution in the flow isolation zone near the center to first fall and then be carried away by the gluconate solution flowing out of the outermost flow isolation zone, forming a comprehensive flow parameter that provides more accurate flow parameter data.

[0052] This embodiment also provides a method for treating gluconate solution with activated carbon, which uses the gluconate solution activated carbon treatment device described in this embodiment, including: obtaining activated carbon addition amount and initial flow rate data based on production information; adding activated carbon according to the activated carbon addition amount; determining the initial addition gas pressure based on the initial flow rate data; obtaining measured flow rate data, establishing a unit addition amount analysis model and determining the actual addition gas pressure; and adjusting the addition gas pressure based on the actual addition gas pressure.

[0053] This method first determines the required amount of activated carbon based on production information. Then, based on equipment design data, it obtains the relationship between the addition pressure and the leakage value of activated carbon from the addition mechanism under pressure. Next, it determines the actual amount of activated carbon to be added based on the real-time detected flow rate of the gluconate solution. Finally, it determines the appropriate gas pressure by referring to the relationship between the activated carbon leakage value and the addition pressure, ensuring accurate adjustment of the addition pressure and guaranteeing that the amount of activated carbon added meets the decolorization requirements of the gluconate solution in real time. Simultaneously, the determination of the activated carbon addition amount can be automatically adjusted in real time, achieving automated operation while ensuring decolorization effect, greatly improving the efficiency of the decolorization process.

[0054] The process of acquiring measured flow rate data, establishing a unit addition analysis model, and determining the actual added gas pressure includes: obtaining a graph showing the relationship between added gas pressure and carbon discharge rate per unit time based on design data; obtaining the theoretical activated carbon decolorization amount U1 per unit volume of gluconate solution; obtaining the measured flow rate data Q1 per unit time, and calculating the actual activated carbon decolorization amount Ux per unit time based on the theoretical activated carbon decolorization amount U1 per unit volume using the following formula: Ux = Q1 * U1; and determining the actual added gas pressure based on the actual activated carbon decolorization amount Ux per unit time, combined with the graph showing the relationship between added gas pressure and carbon discharge rate per unit time. Determining the actual added gas pressure mainly involves determining the amount of activated carbon added that needs to be adjusted according to changes in flow rate, and then determining the actual added gas pressure based on the established relationship between pressure and activated carbon addition amount.

[0055] Specifically, for measured traffic data, obtaining measured traffic data Qa per unit time includes: collecting regional measured traffic datasets {Q1,Q2,…,Qn} within each traffic isolation zone; and determining the mean of the regional measured traffic dataset as the measured traffic data Qa based on the regional measured traffic dataset.

[0056] Because the liquid flow chamber is isolated by multiple flow isolation walls, the flow rate in the flow isolation areas closer to the central axis gradually decreases due to pressure loss when the gluconate solution is injected into the liquid flow chamber. Therefore, to improve the overall flow rate measurement of the gluconate solution, combining the flow rate data measured in each flow isolation area can improve the accuracy of the activated carbon usage data.

[0057] Systematic processing of flow data measured in various flow isolation zones can yield highly accurate actual flow data. Various methods exist for processing regional measured flow datasets, with averaging being a relatively simple and effective approach. This method allows for rapid acquisition of measured flow data, exhibiting fast data processing response and demonstrating simple and efficient processing results for rapidly changing parameters such as solution flow rate. Of course, there are various methods and approaches to better process regional measured flow datasets to obtain more accurate data; any method that accurately acquires the measured flow data is acceptable.

[0058] In summary, the beneficial effects of the gluconate solution activated carbon treatment device and method provided in this application are as follows:

[0059] The activated carbon treatment device for gluconate solution effectively avoids uneven activated carbon content per unit volume caused by adding activated carbon at a constant flow rate without considering the gluconate solution flow rate. This prevents insufficient decolorization and reduced decolorization efficiency. Furthermore, the real-time adjustment of activated carbon addition allows for efficient utilization of activated carbon, effectively reducing waste in decolorization processes that use large amounts of activated carbon, thus mitigating cost savings.

[0060] The activated carbon treatment method for gluconate solution first determines the required amount of activated carbon based on production information. Then, based on equipment design data, it obtains the relationship between the addition pressure and the leakage value of activated carbon from the addition mechanism under pressure. Next, it determines the actual amount of activated carbon to be added based on the real-time detected flow rate of the gluconate solution. The gas pressure is then determined by referring to the relationship between the activated carbon leakage value and the addition pressure, ensuring accurate adjustment of the addition pressure and guaranteeing that the amount of activated carbon added meets the decolorization requirements of the gluconate solution in real time. Simultaneously, the determination of the activated carbon addition amount can be automatically adjusted in real time, achieving automated operation while ensuring decolorization effect, greatly improving the efficiency of the decolorization process.

[0061] Activated carbon is added by applying pressure to the activated carbon stored in the activated carbon storage tube and the adding chamber, forcing the activated carbon out through the activated carbon vent hole and being carried away by the airflow on the surface of the activated carbon adding head. To ensure the activated carbon is carried away by the airflow after extrusion, the pressure applied in the activated carbon storage tube is greater than the gas pressure in the airflow chamber. This pressure difference between the inside and outside of the activated carbon vent hole generates an extrusion force, ensuring the activated carbon is successfully extruded and carried away. The addition amount adjustment disc moves along the axis of the activated carbon storage tube according to the flow rate and the added pressure, opening and closing the vent hole to adjust the amount of activated carbon discharged in real time.

[0062] The amount of activated carbon added will increase with the increase of flow rate. Considering that the activated carbon can be replenished in a timely manner, and that the activated carbon can be quickly mixed into the gluconate solution after being taken away from the activated carbon addition head, the activated carbon addition head is set into a cone-shaped structure. This can ensure that the activated carbon generates radial velocity when moving along the cone surface, and then quickly mixes with the flowing gluconate solution to start the decolorization effect.

[0063] As the amount of activated carbon added increases, the addition pressure will also increase. In order to ensure that a wide range of activated carbon addition adjustments can be achieved in the relatively small structure of the activated carbon addition head, the number of activated carbon discharge holes is increased regularly along the axis of the activated carbon storage tube. This can increase the discharge volume of activated carbon and also determine the pattern of discharge volume, ensuring that the accurate determination of the activated carbon discharge volume can be successfully completed.

[0064] A small gap is formed between the gas-liquid isolation cylinder wall and the activated carbon addition head. On the one hand, this ensures that the activated carbon flows out of the gap in a consistent direction, which facilitates the structural design of the mixing cylinder to ensure uniform mixing of activated carbon and gluconate solution. On the other hand, due to the formation of the gap, the gas velocity in the gas flow chamber increases when passing through the gap. This allows the activated carbon to generate a greater radial velocity and mix quickly with the gluconate solution to carry out the decolorization process as early as possible.

[0065] The main function of the flow guide cover is to adjust the flow rate of the gluconate solution. Without the flow guide cover, the gluconate solution, after entering the liquid flow chamber, will not flow in the predetermined order from the space isolated by the outer flow isolation wall to the space isolated by the innermost flow isolation wall. Instead, it will flow randomly through arbitrary flow gaps. This will make it impossible to accurately measure the flow rate of the gluconate solution. At the same time, due to the random flow of the solution, it is impossible to achieve uniform mixing between the activated carbon and the solution to achieve a good decolorization effect.

[0066] The inclined mixing wall provides a platform for mixing gluconate solution and activated carbon. Upon reaching the inclined mixing wall, the activated carbon and gluconate undergo effective collision mixing, preventing the activated carbon from only contacting the solution surface and providing favorable conditions for uniform mixing. Therefore, the position of the inclined mixing wall also needs to be considered in relation to where the activated carbon falls, preventing it from falling directly into the mixing chamber.

[0067] Considering the gluconate solution flows from the outside in, the flow velocity gradually decreases from the outside to the inside within each flow isolation zone, leading to changes in flow rate and requiring adjustments to the amount of activated carbon. It can be understood that, compared to each flow isolation wall having a uniform height near the bottom of the mixing cylinder, designing the flow isolation walls to have different heights relative to the bottom of the mixing cylinder, gradually increasing from the center outwards, facilitates the guidance of solution flow. Furthermore, it allows the gluconate solution in the flow isolation zone near the center to first fall and then be carried away by the gluconate solution flowing out of the outermost flow isolation zone, forming a comprehensive flow parameter that provides more accurate flow parameter data.

[0068] Because the liquid flow chamber is isolated by multiple flow isolation walls, the flow rate in the flow isolation areas closer to the central axis gradually decreases due to pressure loss when the gluconate solution is injected into the liquid flow chamber. Therefore, to improve the overall flow rate measurement of the gluconate solution, combining the flow rate data measured in each flow isolation area can improve the accuracy of the activated carbon usage data.
