[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This embodiment provides an automatic seasoning system, such as Figure 1As shown, the system includes: an acid storage tank, a material storage tank, a mixing tank, a processor, multiple level gauges, and multiple density meters. The acid storage tank stores an acid solution, the material storage tank stores an oxidizing agent or a reducing agent, and the mixing tank stores a liquid to be adjusted. The acid storage tank is used to inject the acid solution into the mixing tank, the material storage tank is used to inject the oxidizing agent or a reducing agent into the mixing tank, and the mixing tank is used to receive the acid solution and the oxidizing agent or reducing agent for acid adjustment, valence adjustment, and atmosphere adjustment. The multiple level gauges are used to monitor the liquid levels in the acid storage tank, the material storage tank, and the mixing tank during the mixing process, and the multiple density meters are used to obtain the densities in the acid storage tank, the material storage tank, and the mixing tank before mixing. The processor is used to determine the liquid level after mixing based on the liquid level, density, and concentration of the substance in each tank before mixing, and the density and target concentration of the substance in each tank after mixing, according to the conservation of substances before and after mixing, and to control the acid storage tank and the material storage tank to stop injecting into the mixing tank based on the liquid level after mixing.

[0024] Specifically, the post-nuclear treatment in this embodiment mainly involves a three-stage process of adjusting the acidity, valence, and atmosphere of the feed solution to purify or separate relevant substances. Acidity adjustment refers to adjusting the acidity of the feed solution to the level required for subsequent processes; valence adjustment refers to adjusting the valence state of the substances to be purified or separated in the feed solution to the valence state required for subsequent processes; and atmosphere adjustment refers to the addition of an appropriate amount of oxidant or reductant after the acidity and valence adjustment processes to ensure the stability of the valence state of the substances to be purified or separated in the feed solution and prevent oxidation or reduction, thereby adjusting the atmosphere in the treatment tank to an oxidizing or reducing atmosphere.

[0025] To achieve the aforementioned three-stage adjustment process, the liquid to be treated is stored in an adjustment tank. Simultaneously, an acid storage tank and a material storage tank are installed in the system. The acid storage tank contains an acid solution. The acid storage tank and the adjustment tank are connected by pipelines, and a valve is installed at the outlet of the acid storage tank. When adjusting the acid content of the liquid in the adjustment tank, the valve of the acid storage tank is opened, allowing the acid solution in the acid storage tank to enter the adjustment tank. The material storage tank contains an oxidizing agent or a reducing agent. The material storage tank is also connected to the adjustment tank by pipelines, and a valve is installed at the outlet of the material storage tank. When adjusting the acid content and atmosphere of the liquid in the adjustment tank, the valve of the material storage tank is opened, allowing the oxidizing agent or reducing agent in the storage tank to enter the adjustment tank. This causes the substance to be purified or separated in the adjustment tank to be oxidized or reduced, and the atmosphere in the adjustment tank becomes an oxidizing or reducing atmosphere. It should be noted that the storage tank can be used to store either an oxidant or a reducing agent, depending on the specific substance to be purified or separated in the seasoning tank. For example, if the substance needs to be purified or separated by oxidation, then an oxidant will be stored in the storage tank.

[0026] In this embodiment, to minimize the impact of unnecessary parameters on automatic mixing, the three-stage mixing process is simplified. This process ensures that no gas or precipitation is generated during the reaction, and the mixing tank always maintains a homogeneous and stable solution. Furthermore, before mixing, the substance to be purified or separated has only one valence state, and after mixing, it has only one valence state different from the one before mixing. Based on this, a level gauge and a density meter are installed in the system. By collecting the level and density data from the level and density meters, along with the concentrations of the relevant substances before mixing and the desired concentrations after mixing, and based on the conservation of mass during the mixing process, the target liquid level in each tank can be determined when the target concentration of the substance is reached. Therefore, the liquid level in each tank can be monitored in real time using the level gauges. When the target liquid level is reached, the valves at the outlets of the acid-adjusting tank and the storage tank can be closed, thus completing the automatic mixing process.

[0027] In one alternative implementation, such as Figure 1 As shown, when the system requires steam or when steam is generated in the seasoning tank due to heating by other heat sources or electricity, a condenser and a filter can be installed in the system. Both the condenser and the filter are connected to the seasoning tank. When steam is generated in the seasoning tank, the steam is condensed by the condenser and filtered by the filter before being returned to the seasoning tank. Simultaneously, after installing the condenser and filter, non-condensable gases may be directly output from the system through the condenser and filter. The mass of this non-condensable gas is negligible relative to the mass of the acid storage tank, the material storage tank, and the solution in the seasoning tank; that is, the mass of this non-condensable gas is not considered in the mass conservation calculations.

[0028] In this invention, by setting up an acid storage tank, a material storage tank, a seasoning tank, a level gauge, and a density gauge in the system, the seasoning endpoint can be automatically calculated and determined based on the relevant parameters obtained from the level gauge and density gauge, and the principle of mass conservation during the seasoning process. Compared with the seasoning operation in related technologies, the seasoning time can be shortened, the manual operation steps can be reduced, the seasoning efficiency can be improved, and the entire nuclear post-processing process can be accelerated.

[0029] According to an embodiment of the present invention, an automatic seasoning method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] This embodiment provides an automatic seasoning method that can be used in electronic devices such as computers, mobile phones, and tablets. Figure 2 This is a flowchart of an automated feeding method for a nuclear reprocessing plant according to an embodiment of the present invention, such as... Figure 2As shown, the process includes the following steps:

[0031] Step S101: Obtain the liquid level, density, and substance concentration of each tank before seasoning, and the density and target substance concentration of each tank after seasoning. Specifically, the liquid level of each tank before seasoning can be collected using a level gauge corresponding to each tank. This level gauge can also monitor the liquid level of each tank in real time during the seasoning process. Furthermore, since each tank stores liquid, the density of each tank before seasoning can be obtained using a density gauge corresponding to each tank. Moreover, the density of the storage tank and acid storage tank does not change during seasoning; therefore, only the density of the seasoning tank during the seasoning process needs to be monitored.

[0032] Regarding the concentration of substances, the acid storage tank contains an acid solution, and the material storage tank contains an oxidizing agent or reducing agent. During the conditioning process, the concentration of acid in the acid solution and the concentration of oxidizing or reducing agent in the material storage tank remain unchanged. Therefore, the concentration of substances in the acid storage tank and the material storage tank can be obtained only before conditioning. For the conditioning tank, the concentrations of acid, oxidizing or reducing agent, and the concentration of the substance to be purified or separated in its solution continuously change during conditioning, allowing for real-time monitoring of the concentrations of relevant substances. Furthermore, the target concentrations of relevant substances can be determined based on the requirements of this three-stage conditioning process, namely, the specific requirements for acid conditioning, conditions, and atmosphere conditioning.

[0033] Step S102: Determine the volume of each tank based on the liquid level and the volumetric level function of each tank. Specifically, to facilitate the calculation of the conservation process, this embodiment converts the acquired liquid level into volume using the volumetric level function, thereby enabling the calculation of mass based on volume and density. The volumetric level function can be determined through pre-calibration. Furthermore, since the solutions in each tank are different, their volumetric level functions are also different, therefore, each tank needs to be calibrated separately. During calibration, the volume corresponding to the liquid level change when each tank holds the corresponding solution can be obtained. Then, the correspondence between the acquired liquid level and volume is fitted to obtain the volume-level function of the acid storage tank, material storage tank, and seasoning tank. The independent variable of this function is the liquid level, and the dependent variable is the volume.

[0034] In this embodiment, the volume-level function f1 of the acid storage tank is expressed as:

[0035] V = f1(h)

[0036] The volume-level function f2 of the storage tank is expressed as:

[0037] V = f2(h)

[0038] The volume-level function f3 of the seasoning tank is expressed as:

[0039] V = f3(h)

[0040] In the formula, V represents the volume and h represents the liquid level.

[0041] Step S103: Based on density, substance concentration, target substance concentration, and volume, the liquid level after seasoning is determined according to the conservation of mass before and after seasoning, and the seasoning endpoint is determined based on the liquid level after seasoning. Specifically, based on the relevant parameters obtained before and during seasoning, such as density, substance concentration, target substance concentration, and volume, the target liquid level of each tank when the target substance concentration is reached can be calculated through the conservation of mass during seasoning. Therefore, the liquid level of each tank can be monitored in real time using a level gauge. When the target liquid level is reached, it indicates that the seasoning endpoint has been reached, and the valves at the outlets of the acid-adjusting tank and the storage tank can be closed, thus completing the automatic seasoning process.

[0042] This embodiment provides an automated material preparation method for a nuclear reprocessing plant, the method comprising the following steps:

[0043] Step S201: Obtain the liquid level, density, and substance concentration of each tank before seasoning, and the density and target substance concentration of each tank after seasoning; for details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0044] Step S202: Determine the volume of each tank based on the liquid level and the volume-level function of each tank; for details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0045] Step S203: Based on density, substance concentration, target substance concentration, and volume, determine the liquid level after seasoning according to the conservation of substances before and after seasoning, and determine the seasoning endpoint based on the liquid level after seasoning. Specifically, the acidic substances in both the seasoning tank and the storage tank are the first substance A, and the storage tank contains the second substance B in the first valence state. p+ As an oxidizing or reducing agent, the seasoning tank before seasoning contains a second substance B in its first valence state. p+ And the third substance C in the first valence state m+ The third substance is the substance to be purified or separated. The seasoning tank after seasoning includes the first substance A and the second substance B in the first valence state. p+ The second substance B in the second valence state q+ The third substance C in the second valence state n+ The target concentration of the substances includes the first concentration C of the first substance A in the seasoning tank after seasoning. 312 And the second substance B in the first valence state p+ The second concentration of C 322 The seasoning process requires the third substance C in its first valence state to be...m+ All are converted into the third substance C in the second valence state. n+ Therefore, the third substance C in the first valence state in the seasoning tank after seasoning... m+ The concentration should be 0. Meanwhile, during the price adjustment process, B... p+ It has two uses, one part is for use with C m+ A chemical reaction occurs until C m+ The remaining portion is used to adjust the atmosphere within the seasoning tank. Therefore, after reaching the adjustment endpoint, the amount of B in the seasoning tank after seasoning can be determined according to the atmosphere adjustment requirements. p+ The second concentration of C 322 .

[0046] The law of conservation of matter includes the conservation of mass, the conservation of hydrogen ions, the conservation of electrons during the reaction, and the conservation of a second substance. The conservation of matter before and after seasoning is determined using the following steps:

[0047] Step S2031: Determine mass conservation based on the fact that the sum of the products of the volumes and densities of each tank before seasoning is equal to the sum of the products of the volumes and densities of each tank after seasoning; specifically, this mass conservation is expressed as:

[0048] f1(h 11 )ρ 11 +f2(h 21 )ρ 21 +f3(h 31 )ρ 31 =f1(h 12 )ρ 12 +f2(h 22 )ρ 22 +f3(h 32 )ρ 32

[0049] In the formula, h 11 and h 12 The h represents the liquid level of the solution in the acid storage tank before and after seasoning. 21 and h 22 The h represents the liquid level of the solution in the storage tank before and after seasoning. 31 and h 32 ρ represents the liquid level of the solution in the seasoning tank before and after seasoning. 11 and ρ 12 ρ represents the density of the solution in the acid storage tank before and after seasoning. 21 and ρ 22 ρ represents the density of the solution in the storage tank before and after seasoning. 31 and ρ 32 These represent the densities of the solution in the storage tank before and after seasoning, respectively. The liquid level before seasoning can be measured using a level gauge, i.e., h. 11 h 21 and h31 These can be measured using a level gauge. The density of the solution in the acid storage tank and the material storage tank does not change before and after preparation because ρ... 11 ρ 21 ρ 21 and ρ 22 The density of the solution in the acid storage tank and the material storage tank before seasoning can be determined by measuring the density of the solution in the seasoning tank before seasoning. Simultaneously, the density ρ of the solution in the seasoning tank before seasoning... 31 It can also be determined by measurement with a densitometer; therefore, in this formula, h 12 h 22 h 32 ρ 32 It is an unknown quantity.

[0050] Step S2032: The conservation of hydrogen ion quantity is determined by the fact that the sum of the products of the volume of the acid storage tank before and after seasoning and the concentration of the first substance, and the sum of the products of the volume of the seasoning tank and the concentration of the first substance, are equal. Since hydrogen ions exist in acid, the conservation of hydrogen ion quantity (i.e., amount of substance) can be determined by calculating the amount of acid. Specifically, the conservation of hydrogen ion quantity can be expressed by the following formula:

[0051] f1(h 11 C 11 +f3(h 31 C 311 =f1(h 12 C 12 +f3(h 32 C 312

[0052] In the formula, C 11 and C 12 The concentrations of acidic substances (substance A) in the acid storage tank before and after seasoning are respectively represented by C. 311 and C 312 These represent the concentrations of the acidic substance, i.e., substance A, in the seasoning tank before and after seasoning. The concentration of substance A in the seasoning tank remains unchanged before and after seasoning; therefore, C... 11 and C 12 The concentration of acid (A) in the acid storage tank before seasoning can be determined. Simultaneously, the concentration of acid (C) in the seasoning tank before seasoning can also be determined. 311 It can also be predetermined, and the concentration C of A in the seasoning tank after seasoning is determined. 312 It can be determined by the specific requirements of the acid adjustment process, that is, by the target concentration of the substance.

[0053] Step S2033: Determine the electron conservation during the reaction process based on the chemical reaction equations of the second and third substances and their valence states before and after seasoning; specifically, in this embodiment, in order to obtain the substance to be purified or separated, an oxidizing agent or a reducing agent (i.e., the second substance) is used to adjust its valence, that is, the third substance C in the first valence state is... m+ All are converted into the third substance C in the second valence state. n+ This transformation process is the redox process between the second and third substances, and the chemical reaction equation for this process is expressed by the following formula:

[0054] bB p+ +cC m+ =bB q+ +cC n+

[0055] In this reaction process, electrons are conserved, i.e., b(qp) = c(mn). Based on this electron conservation, the above chemical reaction equation can be further expressed as (mn) / (qp)B p+ +C m+ =(mn) / (qp)B q+ +C n+ .

[0056] Step S2034: The conservation of the second substance is determined by the fact that the difference in the amount of the second substance in its first valence state before and after seasoning is equal to the sum of the second substance in its first valence state reacting with the third substance in its first valence state in the seasoning tank and the remaining third substance in its first valence state in the seasoning tank after seasoning. Specifically, the conservation of the amount of the second substance is expressed by the following formula:

[0057] (mn) / (qp)f3(h 31 C 331 +f3(h 32 C 322 =f2(h 22 C 22 -f2(h 21 C 21

[0058] In the formula, C 21 and C 22 These represent the second substance B in its first valence state in the storage tank before and after seasoning. p+ The concentration of C 331 Indicates C in the seasoning tank before seasoning. m+ .

[0059] By applying the aforementioned law of conservation of mass and substituting the relevant data into the formula, we can obtain the liquid levels h of the acid storage tank, the material storage tank, and the seasoning tank when the substance in the seasoning tank reaches the target concentration. 12 h22 h 32 .

[0060] As a specific application embodiment of the present invention, such as Figure 3 As shown, this automatic seasoning method is implemented using the following process:

[0061] Step 1: Determine the specific process nodes of the seasoning method. In this embodiment, acid adjustment, valence adjustment, and atmosphere adjustment are the key nodes, while other process flow factors are downplayed. This baseline process flow minimizes the impact of unnecessary parameters on automatic seasoning while ensuring key parameters. In this process flow, no gas or precipitation is generated due to chemical reactions, and the seasoning tank always contains a homogeneous and stable solution. Although steam or other heat sources / electricity are used to heat the seasoning tank in this process, the steam generated in the seasoning tank will be completely condensed into liquid in the condenser and filter and returned to the seasoning tank along the pipeline. The non-condensable gases generated in this process are negligible relative to the mass of the acid storage tank, the storage tank, and the solution in the seasoning tank. Before valence adjustment, the substance to be purified or separated has only one valence state, and after valence adjustment, the substance to be purified or separated has only one valence state different from that before valence adjustment.

[0062] Step 2: Perform volume-level calibration on the acid storage tank, material storage tank, and seasoning tank. After calibration, obtain the volume-level function for each tank. The independent variable of this function is the liquid level, and the dependent variable is the volume.

[0063] Step 3: Activate the online instrumentation system (level gauge, density meter) and automatic sampling and analysis system to record parameters and analyze samples from the solutions in the acid storage tank, material storage tank, and mixing tank. In subsequent discussions, units of physical quantities will not be specified. In practical applications, the units of the same physical quantity must be consistent and identical to the units required by the function.

[0064] Before automatic feeding, the parameters of the acid storage tank include: liquid level h. 11 Density ρ 11 Acid concentration C 11 The acid storage tank does not contain the oxidizing or reducing agents found in the storage tank. The acid in the acid storage tank is represented by the symbol A.

[0065] Before automatic feeding, the parameters of the storage tank include: liquid level h. 21 Density ρ 21 Oxidizing or reducing agent B p+ Concentration C 21 The storage tank does not contain acid. The oxidizing or reducing agent in the storage tank is represented by the symbol B. Before the price adjustment, substance B has a oxidation state of +p, represented by B. p+ Indicates that after the price adjustment, the oxidation state of substance B is +q, expressed in B. q+ express;

[0066] Before automatic seasoning, the parameters of the seasoning tank include: liquid level h. 31 Density ρ 31 Acid concentration C 311 The concentration C of oxidant or reducing agent in the seasoning tank 321 Substance C to be purified or separated m+ Concentration C 331 The acid in the seasoning tank and the acid in the storage tank are the same acid, both being acid A. The oxidizing or reducing agent in the seasoning tank and the oxidizing or reducing agent in the storage tank are the same substance, both being material B. The substance to be purified or separated in the seasoning tank is represented by the symbol C. Before price adjustment, the oxidation state of substance C is +m, represented by C. m+ Represents; after the price adjustment, the valence state of substance C is +n, represented by C. n+ represent.

[0067] The target values ​​for the seasoning include: the concentration C of acid A in the seasoning tank. 312 Substance B in the seasoning tank p+ Concentration C 322 Substance C in the seasoning tank m+ The concentration is 0.

[0068] Before automatic mixing, the volumes of the acid storage tank, material storage tank, and mixing tank are calculated using a volumetric level function. The volume V of the acid storage tank is... 11 =f1(h 11 The volume V of the storage tank 21 =f2(h 21 The volume V of the seasoning tank 31 =f3(h 31 Therefore, we can obtain the mass m of the acid storage tank solution before automatic feeding. 11 =V 11 ρ 11 =f1(h 11 )ρ 11 Mass of solution in storage tank m 21 =V 21 ρ 21 =f2(h 21 )ρ 21 Mass of solution in the seasoning tank (m) 31 =V 31 ρ 31 =f3(h 31 )ρ 31 .

[0069] Step 4: Open the outlet valve of the acid storage tank to begin injecting acid A into the seasoning tank; open the outlet valve of the storage tank to begin injecting substance B into the seasoning tank. When the automatic seasoning endpoint is determined by calculation, close the outlet valve of the acid storage tank to stop acid injection; close the outlet valve of the storage tank to stop injecting substance B.

[0070] Specifically, when the automatic feeding ends, the parameters of the acid storage tank include: liquid level h. 12 Density ρ 12 Acid concentration C 12 , where ρ 12 =ρ 11 C 12 =C 11 .

[0071] When the automatic mixing process ends, the storage tank parameters include: liquid level h. 22 Density ρ 22 Concentration C of substance B 22 Wherein, ρ 22 =ρ 21 C 22 =C 21 .

[0072] When the automatic seasoning process ends, the seasoning tank parameters include: liquid level h. 32 Density ρ 32 Concentration C of acid A 312 Substance B p+ Concentration C 322 Substance B q+ Concentration C 323 Substance C m+ Concentration 0, substance C n+ Concentration C 332 .

[0073] After automatic mixing, the volumes of the acid storage tank, material storage tank, and mixing tank are calculated using a volumetric level function. The volume V of the acid storage tank is... 12 =f1(h 12 The volume V of the storage tank 22 =f2(h 22 The volume V of the seasoning tank 32 =f3(h 32 Therefore, after the automatic feeding is completed, the mass m of the solution in the acid storage tank... 12 =V 12 ρ 12 =f1(h 12 )ρ 12 Mass of solution in storage tank m 22 =V 22 ρ 22 =f2(h 22 )ρ 22 Mass of solution in the seasoning tank (m) 32 =V 32 ρ 32 =f3(h 32 )ρ 32 Among them, h 12 h 22 h32 It is an unknown quantity.

[0074] The liquid level in each tank at the end of the seasoning process can be determined through the following mass conservation process. This mass conservation includes mass conservation, hydrogen ion quantity conservation, electron conservation during the reaction process, and secondary mass conservation.

[0075] The mass conservation of the solution within the system during automatic mixing is expressed by the following formula:

[0076] m 11 +m 21 +m 31 =m 12 +m 22 +m 32

[0077] Right now,

[0078] f1(h 11 )ρ 11 +f2(h 21 )ρ 21 +f3(h 31 )ρ 31 =f1(h 12 )ρ 12 +f2(h 22 )ρ 22 +f3(h 32 )ρ 32

[0079] H during automatic seasoning process + Quantity conservation:

[0080] f1(h 11 C 11 +f3(h 31 C 311 =f1(h 12 C 12 +f3(h 32 C 312

[0081] Chemical equation for the reaction between substance B and substance C during automatic seasoning process

[0082] bB p+ +cC m+ =bB q+ +cC n+ B p+ It has two uses, one part is for use with C m+ A chemical reaction occurs until C m+ No longer exists; the other part is used to adjust the atmosphere inside the seasoning tank.

[0083] Electron conservation in redox reactions:

[0084] b(qp)=c(mn)

[0085] Therefore, we can conclude that:

[0086] (mn) / (qp)B p+ +C m+ =(mn) / (qp)B q+ +C n+

[0087] The quantity of substance B is conserved during automatic seasoning:

[0088] (mn) / (qp)f3(h 31 C 331 +f3(h 32 C 322 =f2(h 22 C 22 -f2(h 21 C 21

[0089] The above formula can be used to solve for f1(h). 12 f2(h) 22 f3(h) 32 Therefore, h can be calculated using the inverse function. 12 =f1 -1 (V 12 ), h 22 =f1 -1 (V 22 ) and h 32 =f1 -1 (V 32 When the liquid levels in the acid storage tank, material storage tank, and seasoning tank reach h 12 h 22 h 32 Automatic seasoning has ended.
