Description

Technical Field

[0001] The present invention relates to the technical field of radioactive material treatment, and in particular to an intelligent treatment system for radioactive waste liquid. Background Art

[0002] With the rapid development of nuclear medicine, radionuclides are widely used in disease diagnosis and treatment. For example, in the diagnosis and treatment of tumors, cardiovascular diseases and nervous system diseases, imaging technologies such as PET-CT and SPECT are indispensable. This growth in demand has led to an increase in the use of radionuclides year by year, and has also brought severe challenges to the management of radioactive waste liquid.

[0003] Radioactive liquid waste is a by-product of nuclear medicine activities. Its main sources include:

[0004] Residual liquid from radionuclide drugs for injection in hospitals.

[0005] Wastewater from cleaning of nuclear medicine imaging equipment.

[0006] Radioactive urine or excreta excreted by the patient.

[0007] These wastes are highly hazardous, long-lasting and complex:

[0008] High hazard: Untreated waste liquid may directly cause radiation pollution to the ecological environment and human health.

[0009] Long-term: Some radionuclides have a long half-life, and the radioactivity in the waste liquid needs to be monitored over a long period of time.

[0010] Complexity: The waste liquid may contain mixed radionuclides, and treatment requires targeted technology.

[0011] With the rapid development of the Internet of Things and artificial intelligence technologies, intelligent waste liquid management has gradually become a research hotspot. For example:

[0012] Automated drainage system: Some hospitals have introduced automated waste liquid collection equipment, but most of them remain at the basic automatic discharge level and fail to achieve in-depth treatment of waste liquid.

[0013] Radiation detection technology: There are online monitoring devices based on radioactive detectors, but most of them are separated from waste liquid treatment equipment and cannot form a unified closed-loop system.

[0014] Industrial waste liquid treatment system: In the chemical industry, intelligent waste liquid separation equipment has achieved a certain degree of automation, but it is not targeted enough and cannot be directly applied to radioactive waste liquid treatment.

[0015] Disadvantages of existing technology

[0016] At present, the treatment methods for radioactive waste liquid mainly include dilution discharge method, sedimentation method, adsorption method and solidification method, but there are still obvious defects:

[0017] Low efficiency: Traditional technologies mostly rely on manual operations or single chemical treatment methods, and cannot achieve efficient and automated waste liquid treatment.

[0018] Incomplete monitoring: In the existing system, radioactivity monitoring is disconnected from the treatment steps, making it difficult to track changes in waste liquid activity in real time.

[0019] High treatment cost: The treatment of some high-activity waste liquids requires special materials or equipment, which is expensive.

[0020] Insufficient environmental protection: Some treatment methods may cause secondary pollution. For example, the adsorption method will produce solid waste containing radioactive adsorption materials.

[0021] Therefore, the present invention provides an intelligent treatment system for radioactive liquid waste. Summary of the invention

[0124] The working principle and beneficial effects of the above technical solution are as follows: In order to collect waste liquid in an orderly manner and avoid leakage, it is necessary to establish a basic working model based on the basic working data of the radiology discipline before collection, locate the waste liquid generating equipment in the basic working model, and then identify the operating parameters of each waste liquid generating equipment, and at the same time identify the initial radioactive objects of the radiology discipline, analyze the estimated radioactive activity of the waste liquid generated this time according to the initial radioactivity of the initial radioactive objects combined with their corresponding activity dissipation characteristics, and estimate the estimated generation amount of the waste liquid generated this time according to the operating parameters of the waste liquid generating equipment, so as to select the container for collecting the waste liquid this time and the collection rate, and construct a feasible waste liquid collection measure, according to which waste liquid collection can be achieved synchronously, and by estimating the generation amount and activity of the waste liquid to configure the corresponding containers, resources can be reasonably allocated, and the service life of each container can be extended, thereby improving the availability and practicality of the system.

[0125] Example 4

[0126] Based on Example 1, the intelligent treatment system for radioactive waste liquid, the radiation detection module, such as Figure 2 As shown, including:

[0127] A mode configuration unit, used to determine an estimated activity range of the waste liquid based on the estimated radioactivity of the waste liquid, search for a basic detection mode corresponding to the estimated radioactivity of the waste liquid, adjust detection parameters of a preset radioactive detector according to the estimated activity range, determine a sampling number of the waste liquid according to the estimated waste liquid generation amount, and correct the basic detection mode based on the detection parameters and the sampling number to obtain a waste liquid detection mode;

[0131] A calibration unit is obtained, which is used to regard the sampling element bits and cross element bits in the sampling matrix as fixed element bits, determine a number of non-fixed element bits contained in the sampling matrix, numerically adjust the non-fixed element bits according to the fixed activity value corresponding to each of the fixed element bits to obtain the activity matrix of the waste liquid, and generate the nuclide activity value of the waste liquid according to the activity matrix.

[0135] In this example, the sampling frequency is related to the estimated waste liquid generation amount, and the sampling frequency increases by one for every 3L increase in the estimated waste liquid generation amount;

[0136] In this example, the waste liquid needs to be sampled uniformly during sampling;

[0137] In this example, the related element bit represents an element bit that a line passes through, and the related element bit represents a related element between the sampled element bits of any two detection results;

[0138] In this example, the cross element bit indicates the element bit corresponding to the intersection of two or more lines;

[0139] In this example, estimating the activity value means determining the value corresponding to the relevant element position by inference;

[0140] In this example, the target cross-element bit identifies the cross-element bit having two or more estimated activity values;

[0141] In this example, replacing the activity value means using the result of variance calculation of the target estimated activity value corresponding to a target cross element position to replace the data of the target estimated activity value at the target cross element position;

[0142] In this example, a fixed element position means that the data value corresponding to the element position is fixed;

[0143] In this example, a non-fixed element bit indicates that the data value at the element bit needs to be adjusted;

[0144] In this example, the process of adjusting the values ​​of non-fixed element positions using fixed activity values ​​is as follows: iteratively deriving the values ​​of non-fixed element positions, then re-determining the fixed element positions, and then cyclically deriving again.

[0145] The working principle and beneficial effects of the above technical solution are as follows: In order to quickly determine the radionuclide activity value of the waste liquid and avoid the uneven distribution of radionuclides in the waste liquid affecting the detection results, before the detection, the evaluation activity range of the waste liquid is determined according to the estimated radioactivity of the waste liquid, the detection parameters of the radioactive detector are determined, and the sampling times are determined according to the amount of waste liquid generated, so as to adjust the basic detection method, adjust the detection parameters and the sampling times, and generate a waste liquid detection method suitable for this detection, so that the waste liquid is sampled under the guidance of the detection method, and the activity of each sample is detected. In order to more intuitively and conveniently derive the activity value of the remaining waste liquid, according to the waste liquid The sampling matrix is ​​established by the sampling arrangement of the samples, and the sampling test results are further input into the sampling matrix. The related element positions between any two sampling test results are determined by the connection method, so as to deduce the estimated activity value of each related element position, and further the numerical value of each cross element position containing multiple estimated activity values ​​is refined to a fixed value. Finally, the activity matrix of the waste liquid is obtained, so that the activity value of each part of the waste liquid can be determined, so as to deduce the accurate nuclide activity value of the waste liquid. In this way, the interference of uneven nuclide distribution on the test results can be effectively avoided, the management difficulty is reduced, and the downtime or delay caused by improper waste liquid treatment is reduced.

[0151] In this example, the activity attribute includes a high activity attribute and a low activity attribute;

[0152] In this example, the activity variation chart represents a chart showing the variation of the activity value composition of the waste liquid at different times.

[0153] The working principle and beneficial effects of the above technical solution are as follows: when treating waste liquid, waste liquids with different activities are treated to different degrees, which can reduce the cost of waste liquid treatment and improve the treatment efficiency, especially when the proportion of high-activity waste liquid is small.

[0159] In this example, the neutralizing liquid refers to a liquid used to neutralize the pH value of the waste liquid;

[0160] In this example, the specified criteria are: compliance with local regulations and social responsibility ordinances;

[0161] In this example, high-activity waste liquid is converted into stable solids through solidification technology, and low-activity waste liquid is diluted and discharged to an area that meets national standards.

[0162] The working principle and beneficial effects of the above technical solution are as follows: by treating waste liquids with different activities differently, the waste liquids can be quickly processed into qualified liquids, and the dependence on high-cost treatment technologies can be reduced through intelligent diversion, and targeted treatment strategies can be adopted to avoid waste of resources.

[0169] A tracking and analysis unit, used for obtaining the corresponding generated processed product after the waste liquid has completed the activity treatment, and determining the corresponding treatment activity value of the generated processed product at different times according to the nuclide activity value change information;

[0170] a depth analysis unit for establishing an activity variation time axis of the generated processed product and identifying a processing dissipation feature of the generated processed product in the activity variation time axis;

[0171] The storage execution unit is used to determine the hazardous radiation level of the generated processed object according to the processing dissipation characteristics, and transport the generated processed object to a radiation storage area of ​​the corresponding level for storage.

[0172] In this example, the process dissipation characteristic represents the dissipation of the activity of the process product generated during the active process.

[0173] The working principle and beneficial effects of the above technical solution: In order to further ensure the quality of system processing and reduce the risk of leakage, after completing the active treatment, the treatment dissipation characteristics of the generated processed material are analyzed according to the corresponding treatment activity values ​​of the generated processed material at different times, and the hazardous radiation level of the generated processed material is further determined based on the treatment dissipation characteristics, so that the generated processed material is transferred to the corresponding radiation storage area for storage. In this way, the risk of radiation leakage caused by human omissions or operational errors during the waste liquid treatment process can be avoided, greatly improving safety.

[0174] Example 9

[0175] Based on Example 1, the intelligent treatment system for radioactive liquid waste further includes:

[0176] A collection monitoring module, used to determine the minimum amount of waste liquid generated within the specified time period according to the waste liquid collection measures;

[0177] Counting the real-time cumulative amount of the waste liquid to determine the actual amount of waste liquid generated within the specified time period;

[0178] When the actual waste liquid generation amount is lower than the minimum waste liquid generation amount, it is determined that the waste liquid collection operation is abnormal, and an abnormality warning is issued.

[0179] In this example, the actual amount of waste liquid generated refers to the actual amount of waste liquid discharged by the radiology department.

[0180] The working principle and beneficial effects of the above technical solution: Since the waste liquid contains radioactive substances, it has certain hazards to the environment and human body. When collecting waste liquid, if the collected waste liquid is obviously less than the amount generated by the radiological discipline, then an early warning will be issued to remind relevant personnel to deal with it as soon as possible to avoid danger.

[0183] The processing control unit is used to determine the real-time processing activity of the waste liquid according to the monitoring data, and when the real-time processing activity meets the low activity attribute, control the processing execution unit to terminate the processing work.

[0184] The working principle and beneficial effects of the above technical solution: During the treatment of waste liquid, when the waste liquid meets the emission standards, the treatment work is stopped, which can effectively reduce irrelevant workload and improve the intelligence of the system.
