[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0057] Example 1:
[0058] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a process optimization and matching system for radioactive waste treatment provided by an embodiment of the present invention.
[0059] like Figure 1 As shown, a process optimization and matching system for radioactive waste treatment includes: a data acquisition module 10, wherein the data acquisition module 10 is configured to collect waste characteristic information of different types of radioactive waste and establish a matching database storing the waste characteristic information corresponding to each type of radioactive waste; a matching module 20, wherein the matching module 20 is configured to generate a waste incineration matching plan for each incinerator based on the matching database and matching requirement standards; a process optimization module 30, wherein the process optimization module 30 is configured to construct an optimization objective function with the goal of maximizing the weight of radioactive waste incinerated per second, and use an improved constrained particle swarm optimization algorithm to solve most of the optimization objective functions to obtain an optimal waste incineration matching plan for each incinerator; and a process control module 40, wherein the process control module 40 is configured to execute the radioactive waste incineration task of each incinerator according to the optimal waste incineration matching plan.
[0060] It should be noted that existing methods for compatibility of radioactive waste typically rely on manual screening and calculation, which lacks intelligence and automation, and results in low compatibility efficiency. To address this issue, this embodiment generates multiple compatibility schemes by collecting relevant properties of radioactive waste. With the goal of maximizing the weight incinerated per second, an optimization function is constructed. This optimization function is solved using an improved constrained particle swarm optimization algorithm, generating the optimal compatibility scheme for each incinerator. Finally, waste sorting, transportation, and incineration are completed based on the optimal compatibility scheme, significantly improving incineration efficiency.
[0061] In a preferred embodiment, the waste characteristic information includes: the composition, physical properties, chemical properties and radioactivity of the radioactive waste; wherein, the data acquisition module specifically includes: a composition query unit, which is configured to identify the identification information of the radioactive waste and match the composition of the radioactive waste in the procurement list according to the identification information; a property determination unit, which is configured to determine the physical and chemical properties of the radioactive waste based on the composition of the radioactive waste; wherein, the physical properties include mass, volume, density, melting point, boiling point and magnetism, and the chemical properties include thermal stability, oxidizability, reducibility and acidity and alkalinity; a radioactivity measurement unit, which is configured to call the manual sampling and measurement results of the radioactive waste to obtain the radioactivity of the radioactive waste; wherein, the radioactivity includes the type and content of nuclides and the radioactivity grade of nuclides.
[0062] The property determination unit specifically includes: a physical property retrieval subunit, which is configured to search for the fixed physical properties of radioactive waste on the Internet based on the components of the radioactive waste; a physical property measurement subunit, which is configured to call the manual measurement results of the non-fixed physical properties of the radioactive waste to obtain the non-fixed physical properties of the radioactive waste; a chemical property retrieval subunit, which is configured to search for some chemical properties of the radioactive waste on the Internet based on the components of the radioactive waste; and a chemical property extraction subunit, which is configured to generate a retrieval log based on the remaining chemical properties that have not been retrieved on the Internet, send the retrieval log to the manufacturer of the radioactive waste, and extract the remaining chemical properties of the radioactive waste from the chemical property report fed back by the manufacturer.
[0063] In this embodiment, for the analysis of radioactive waste components, the data acquisition module reads the identification information (production number, brand, and category) of the target waste. Since the target waste is usually purchased with a complete purchase list, which indicates the components of the target waste, the purchase list database is searched using the production number, brand, and category to obtain the corresponding component list. For the analysis of the physical properties of radioactive waste, the melting point, boiling point, and magnetic properties are obtained based on the components through internet searches. The volume can be measured using the displacement method, the mass can be measured using a gravimeter, and the density can be obtained by converting weight to volume. For the analysis of the chemical properties of radioactive waste, the chemical properties of the relevant components are searched via the internet. Because some chemical properties of some components are difficult to retrieve via the internet, the unretrieved chemical properties are fed back to the relevant staff in the form of a search log. The staff can obtain the information by consulting the target waste manufacturer. For the analysis of the radioactivity of radioactive waste, manual sampling is used. Therefore, this embodiment queries the composition of radioactive waste and, based on the obtained composition, obtains the incineration-related properties of each type of radioactive waste through Internet search, manual measurement, consultation with manufacturers, and manual sampling and analysis. The above-mentioned incineration-related properties are structured and stored in the compatibility database, providing attribute data support for subsequent radioactive waste compatibility for each incinerator. This ensures that the radioactive waste incineration of each incinerator meets the incineration standards while improving the efficiency of radioactive waste incineration and preventing unscientific compatibility during incineration from damaging the incinerator and shortening the incinerator's life.
[0064] In a preferred embodiment, the matching module specifically includes: an incineration environment acquisition unit, the incineration environment acquisition unit is configured to obtain the incineration temperature of each incinerator when performing the radioactive waste incineration action; an incineration requirement standard generation unit, the incineration requirement standard acquisition unit is configured to generate an incineration requirement standard according to the radioactive waste incineration specification; a radioactive waste matching unit, the radioactive waste matching unit is configured to query the waste characteristic information corresponding to each radioactive waste in the matching database, and perform exhaustive matching of the radioactive waste to be incinerated based on the waste characteristic information corresponding to the radioactive waste to be incinerated and the incineration temperature of each incinerator, under the restriction of the incineration requirement standard, so that the radioactive waste to be incinerated matched by each incinerator meets the incineration requirement standard, and obtain a waste incineration matching scheme S (s1, s2, ..., s n ), n represents the number of combination schemes.
[0065] Specifically, under the restriction of the incineration requirements, the exhaustive matching of radioactive wastes to be incinerated is performed so that the radioactive wastes to be incinerated matched with each incinerator meet the incineration requirements, including: (1) judging whether the radioactive wastes to be incinerated matched with the incinerator can be kept stable at the incineration temperature corresponding to the incinerator according to the thermal stability of the radioactive wastes to be incinerated. If so, the incineration requirements standard 1 is met; (2) judging whether the radioactive wastes to be incinerated in the incinerator can undergo chemical reactions to produce flammable gases and toxic gases at the corresponding incineration temperature according to the oxidizability, reducibility and acidity and alkalinity of the radioactive wastes to be incinerated. If not, the incineration requirements standard 2 is met; (3) judging whether the current matching scheme is different from the incineration scheme in the previous matching scheme according to the last matching scheme of the incinerator. Whether the Cl content of the radioactive waste to be incinerated in the incinerator is less than 1%, whether the F content is less than 0.5%, whether the P content is less than 0.5%, and whether the heavy metal and alkali metal content is less than 1%. If so, the incineration requirement standard three is met; (4) According to the type of nuclides of the radioactive waste to be incinerated in the incinerator, it is judged whether the content of volatile nuclides in the radioactive waste to be incinerated in the incinerator does not exceed the threshold value. If so, the incineration requirement standard four is met; (5) According to the radioactivity grade of the nuclides of the radioactive waste to be incinerated in the incinerator, it is judged whether there is reflective waste to be incinerated with a preset radioactivity grade of nuclides in the incinerator. If not, the incineration requirement condition five is met; if all the above incineration requirements are met, the radioactive waste to be incinerated in each incinerator meets the incineration requirement standard.
[0066] In this embodiment, the most basic requirements that the radioactive waste to be incinerated in each incinerator must meet are considered (including the requirements of complying with incineration regulations and the requirements of not damaging the incinerator). Specifically, to meet the requirements of the incineration regulations, it is necessary to ensure that the waste can be stable at the incineration temperature of the target incinerator; to ensure that the waste does not undergo chemical reactions at the target incinerator temperature to generate flammable and toxic gases; to ensure that the content of volatile nuclides does not exceed the threshold; and to ensure that there is no waste of a preset specific radioactive level. In other words, the requirements and standards for incineration emissions and incineration efficiency in the incineration regulations are met. Specifically, to meet the requirements of not damaging the incinerator, it is necessary to ensure that the Cl content of the waste in this combination is less than 1%, the F content is less than 0.5%, the P content is less than 0.5%, and the heavy metal and alkali metal content is less than 1% compared to the previous combination. In other words, by ensuring that the content of acidic substances entering the furnace does not corrode the incinerator during continuous incineration, the requirements of not damaging the incinerator are met. This improves the incineration efficiency and cleanliness of the incinerator and reduces incineration losses.
[0067] In a preferred embodiment, the process optimization module specifically includes: an optimization objective function construction unit; wherein the optimization objective function construction unit is configured to obtain the average processing time per unit weight of each processing line for different types of radioactive waste at each link And each incinerator can also add the waste weight W (w1, w2, ..., w p ), construct an optimization objective function with the goal of maximizing the weight of radioactive waste incinerated per second; where k represents the weight of radioactive waste, i represents the number of processing lines, m represents the number of processing links, and p represents the number of incinerators
[0068] On this basis, the expression of the optimization objective function is specifically:
[0069]
[0070] Where ξ represents the proportionality parameter, f(ξ·,·) represents the calculation of ξ so that the left side is less than or equal to the right side, and g(λ) represents the type λ of waste in s γ where τ is the unit weight and E is the total weight.
[0071] Specifically, the process optimization module includes: a particle swarm optimization solution unit; wherein the particle swarm optimization solution unit is configured to use the improved constrained particle swarm optimization algorithm to iteratively solve the majority optimization objective function MAX(E) to maximize E and obtain the optimal waste incineration combination plan S'(s'1,...,s' p ); where the numerator of the optimization objective function MAX(E) is the total weight of each combination scheme that meets the maximum waste addition condition, and the denominator is the total processing time of various types of waste in each combination scheme under all treatment lines.
[0072] Among them, the expression of the improved constrained particle swarm optimization algorithm is specifically:
[0073]
[0074] in, is the moving distance and direction of the particle in the next iteration, is the historical optimal position of particle a in the k-th step in dimension d, is the historical optimal position of the group. If different processing links are considered independent, this is inconsistent with the fact of the processing line. Some specific combinations of processing links are constrained to one processing line. Then the particle learning factor and the group learning factor theory should not exceed a certain threshold. h represents a specific threshold, b represents the inertia weight, c1 represents the learning factor, and r1 represents the scaling factor, which represents the weight and time ratio of each combination scheme under each processing line.
[0075] In this embodiment, the process optimization module is set up to combine the real-time link of waste treatment with the matching scheme generated by the matching module to optimize the treatment process. First, the average treatment time T of each treatment line at each link for different types of waste per unit weight is obtained by statistical means. i Then, the weight of waste that can be added to each incinerator is obtained, and the optimization objective function is constructed with the maximization of the weight of waste incinerated per second as the optimization goal. After that, the MAX(E) is iteratively solved by the improved constrained particle swarm optimization algorithm to maximize E. The solution is S'(s'1,…,s' p ); Therefore, by considering the specific conditions of different links in the incinerator during the radioactive waste incineration process, the total weight of waste incinerated per second by all incinerators on each processing line is calculated. The particle swarm optimization iterative solution is used to maximize the total weight as the optimization goal, thereby achieving more efficient, more economical and more environmentally friendly radioactive waste incineration control.
[0076] In a preferred embodiment, the process control module specifically includes: a compatibility and incineration execution unit; wherein the compatibility and incineration execution unit is configured to calculate the waste incineration compatibility according to the optimal waste incineration compatibility scheme S'(s'1,...,s' p ) for each incinerator's matching scheme, controls the robotic arm to complete the radioactive waste sorting and transportation actions corresponding to the matching scheme, and controls the incinerator to complete the incineration action. Specifically, after obtaining the optimal waste incineration matching scheme, the matching scheme corresponding to each incinerator can be sent to the robotic arm control terminal and the incinerator control terminal, thereby controlling the robotic arm to complete the radioactive waste sorting and transportation actions corresponding to the matching scheme, and controlling the incineration rate to complete the incineration action.
[0077] Therefore, this embodiment proposes a process optimization and matching scheme for radioactive waste treatment. By collecting relevant properties of the waste to generate multiple matching schemes, an optimization function is constructed with the goal of maximizing the incineration weight per second. The optimization function is solved by an improved constrained particle swarm optimization algorithm to generate the optimal matching scheme corresponding to each incinerator. Finally, the waste sorting, transportation, and incineration tasks are completed according to the optimal matching scheme, greatly improving the incineration efficiency.
