Detailed implementation manners

[0041] To make the above objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0042] Refer to Figure 1 As shown, the present application provides a washing system 100 for radioactive protection products in a nuclear power plant, including a first pollution detection module 110, a washing module 120 and a controller (not shown). The first pollution detection module 110 is used to detect the first radiation dose of the protection products. The washing module 120 is used to wash the protection products.

[0043] The controller is electrically connected to the first pollution detection module 110 and the washing module 120. The controller is configured to control the switching of the washing module 120 between a first working state and a second working state according to the first radiation dose detected by the first pollution detection module 110. Wherein, the first working state includes a working state in which the washing module 120 can clean the protective articles, and the second working state includes a working state in which the protective articles are processed by the solid waste treatment system.

[0044] Wherein, the protective articles may refer to the articles worn in the working environment, such as clothes, trousers, shoes and other articles.

[0045] Specifically, as Figure 2 shown, the radioactive protective article washing system 100 of the nuclear power plant can be used to implement the radioactive protective article washing method of the nuclear power plant. The radioactive protective article washing method of the nuclear power plant includes:

[0046] S1. Obtain the first radiation dose of the protective article.

[0047] S2. Determine whether the first radiation dose is less than or equal to a first preset value.

[0048] When the first radiation dose is less than or equal to the first preset value, then: execute step S21, start the first working state to clean the protective article.

[0049] That is, when the first radiation dose is less than or equal to the first preset value, the washing module 120 is driven to clean the protective article. After the protective article is washed and dried, it can be recycled.

[0050] When the first radiation dose exceeds the first preset value, then: execute step S22, start the second working state to place the protective article into the solid waste system for treatment.

[0051] That is, when the first radiation dose exceeds the first preset value, the washing module 120 does not wash the protective article. In some example scenarios, the protective articles with the first radiation dose exceeding the first preset value can be placed in the fixed waste system for centralized treatment and no longer washed and reused. Wherein, the fixed waste system refers to a treatment system that can perform any one or a combination of chemical cleaning, incineration, landfill and other treatment methods on the protective articles.

[0052] It is understandable that for highly radioactive contaminated items, the radioactivity remains relatively strong after cleaning and is not suitable for recycling cleaning and continued use. Therefore, the second working state can be adopted to avoid unnecessary waste of cleaning resources and avoid increasing the amount of waste liquid to be treated. Correspondingly, for low-radioactivity contaminated items, the radioactivity concentration of the protective gear can be reduced through cleaning, so that the radioactivity of the cleaned protective gear will not cause excessive harm to the human body, and it is suitable for recycling cleaning and continued use, which is convenient for reducing production costs and resource waste.

[0053] It should be noted that the washing module 120 in the above embodiments can be, but is not limited to, a washing machine, a shoe washing machine, etc., and no further limitations are made here.

[0054] In some embodiments, see Figure 1 , the radioactive protective gear washing system 100 of the nuclear power plant further includes a sewage treatment module 130. The sewage treatment module 130 includes at least two filtering modules 131 and a pipeline assembly 132. The pipeline assembly 132 is connected between the filtering module 131 and the washing module 120. The filtering module 131 is used to filter the waste liquid discharged from the washing module 120.

[0055] In this way, the filtering module 131 can effectively remove impurities and harmful substances in the waste liquid, ensure that the discharged waste liquid meets the environmental protection standards, and reduce the impact on the environment.

[0056] Specifically, as Figure 3 shown, the radioactive protective gear washing method of the nuclear power plant may further include:

[0057] S3. When starting the first working state, filter the waste liquid generated by cleaning the protective gear;

[0058] Among them, step S3 further includes:

[0059] S31. Judge whether the first radiation dose is greater than the second preset value.

[0060] When the first radiation dose is greater than the second preset value, then execute step S311. Start the first filtering state to filter and process the waste liquid through a filtering module.

[0061] That is, when the first radiation dose of the protective gear is relatively high, the waste liquid can be filtered and processed through a filtering module.

[0062] When the first radiation dose is less than or equal to the second preset value, then execute step S312. Start the second filtering state to filter and process the waste liquid through another filtering module.

[0063] That is, when the first radiation dose of the protective gear is relatively low, the waste liquid can be filtered and processed through another filtering module.

[0064] In this way, according to the radiation level of the first radiation dose, different filtering modules 131 are selected, avoiding the contamination of protective articles caused during mixed processing.

[0065] Furthermore, in one embodiment, referring back Figure 1 , the filtering module 131 includes a first filter 1311 and a second filter 1312. The first filter 1311 is connected to the washing module 120 through a pipeline assembly 132, and the second filter 1312 is connected to the pipeline assembly 132 and the washing module 120 by being connected to the first filter 1311.

[0066] It should be noted that the first filter 1311 and the second filter 1312 can be implemented by physical filtering methods such as filtering through a filter mesh, or by chemical filtering methods such as using ion exchange resins to adsorb radioactive ions. Additionally, the filtering methods used by the first filter 1311 and the second filter 1312 can be the same or different.

[0067] Combined with any embodiment of the above first filter 1311 and second filter 1312, the filtering levels of the first filter 1311 and the second filter 1312 can be different, and the filtering level of the first filter 1311 is greater than that of the second filter 1312. At this time, according to the radiation level of the first radiation dose, different filtering modules 131 are selected, which is beneficial to avoiding phenomena such as reduced efficiency or waste of resources caused by using the first filter 1311 for a lower level of the first radiation dose.

[0068] In one implementation manner, the first filter 1311 includes a first filter mesh. The second filter 1312 includes a second filter mesh. Among them, the aperture of the first filter mesh is larger than that of the second filter mesh. In this way, when the waste liquid passes through the filtering module 131, coarse filtering can be achieved through the first filter mesh to filter out larger radioactive substances and avoid blocking the pipeline assembly 132. And finer radioactive substances can be filtered through the second filter mesh. The double filtering is beneficial to improving the treatment precision of the waste liquid.

[0069] In one example, the aperture of the first filter mesh is between 2.5 mm and 1.5 mm. The aperture of the second filter mesh is between 0.5 mm and 1 mm.

[0070] In this way, the aperture design of this size enables the first filter mesh to effectively block larger impurities and particles, while the second filter mesh can further filter out fine particles, ensuring that the waste liquid is fully purified when passing through the filtering module 131, improving the efficiency of waste liquid treatment and also avoiding blockage of the pipeline assembly 132 due to impurities.

[0071] In addition, in other implementation manners, referring back Figure 1, the radioactive protection article washing system 100 of the nuclear power plant further includes a switching valve assembly 133, and the switching valve assembly 133 includes a first switching valve 1331 and a second switching valve 1332. The pipeline assembly 132 includes a first pipeline assembly 1321 and a second pipeline assembly 1322. The filtering module 131 includes a first filtering module 131a and a second filtering module 131b. The first filtering module 131a is communicated with the washing module 120 through the first pipeline assembly 1321, and the first switching valve 1331 is communicatively arranged on the first pipeline assembly 1321. The second filtering module 131b is communicated with the washing module 120 through the second pipeline assembly 1322, and the second switching valve 1332 is communicatively arranged on the second pipeline assembly 1322. In some embodiments, the switching valve assembly 133 can be electrically connected to a controller to control the opening degrees of the first switching valve and the second switching valve according to the first radiation dose through the controller.

[0072] Specifically, as Figure 4 shown, in one embodiment, step S31 may further include:

[0073] S31. Determine whether the first radiation dose is greater than a second preset value.

[0074] When the first radiation dose is greater than the second preset value, then perform step S3111: open the first switching valve 1331 and close the second switching valve 1332, so that the waste liquid can be discharged to the first filtering module 131a through the first pipeline assembly 1321, and the first filtering module 131a filters the waste liquid.

[0075] That is, when the first radiation dose of the protection article is relatively high, the waste liquid can be filtered by the first filtering module 131a.

[0076] When the first radiation dose is less than or equal to the second preset value, then perform step S3112: open the second switching valve 1332 and close the first switching valve 1331, so that the waste liquid can be discharged to the second filtering module 131b through the second pipeline assembly 1322, and the second filtering module 131b filters the waste liquid.

[0077] That is, when the first radiation dose of the protection article is relatively low, the waste liquid can be filtered by the second filtering module 131b.

[0078] In this way, according to the radiation level of the first radiation dose, different filtering modules 131 are selected, avoiding the contamination of the protection articles caused by mixed treatment.

[0079] Combined with any one of the above embodiments of the radioactive protection article washing system 100 of the nuclear power plant, referring back to Figure 1 , the radioactive protection article washing system 100 of the nuclear power plant further includes a drying module 140, and the drying module 140 is used for drying the protection articles.

[0080] Further, in some embodiments, the radioactive protection article washing system 100 of the nuclear power plant further includes a second pollution detection module 150, and the second pollution detection module 150 is used to detect the second radiation dose of the protection articles after being dried by the drying module 140. The second pollution detection module 150 can be electrically connected to the controller, so that the controller can control the washing module 120 to switch between the first working state and the second working state according to the second radiation dose detected by the second pollution detection module 150.

[0081] Specifically, as Figure 5 shown, in step S21 of starting the first working state to clean the protection articles, the radioactive protection article washing method of the nuclear power plant further includes:

[0082] S4. Dry the protection articles.

[0083] S5. Obtain the second radiation dose of the protection articles.

[0084] S6. Determine whether the second radiation dose exceeds a third preset value. Among them, the third preset value is less than or equal to the first preset value.

[0085] When the second radiation dose exceeds the third preset value, then execute step S61 to determine that the protection articles are in an abnormal state.

[0086] When the second radiation dose is less than or equal to the third preset value, then execute step S62 to determine that the protection articles are in a normal state. Specifically, when the protection articles are in a normal state, the protection articles can be recycled.

[0087] It can be understood that when detecting the second radiation dose of the dried protection articles and judging whether the protection articles are normal through the second radiation dose, it avoids the recycling of the protection articles with strong radioactivity that are not cleaned properly, and improves the reliability of the protection article system.

[0088] As Figure 6 shown, the radioactive protection article washing method of the nuclear power plant further includes:

[0089] S7. Obtain the occurrence times N of the second radiation dose of the protection articles in an abnormal state.

[0090] S8. Determine whether the occurrence times are greater than or equal to two, that is, determine whether N ≥ 2 exists.

[0091] When the occurrence times are greater than or equal to two, then start the second working state to place the protection articles into the solid waste system for treatment.

[0092] When the occurrence count is one, the first working state is activated to clean the protective gear. That is, when the occurrence count is one, the protective gear is re-cleaned, and after drying, the second radiation dose is obtained again.

[0093] In this way, for the protective gear that shows abnormal radiation dose only in one detection, the nuclear power plant radioactive protective gear washing system 100 in this embodiment can re-clean the protective gear. If the protective gear still shows a relatively high radiation dose after drying and detection twice or more, this may mean that the radioactive substances on the protective gear are difficult to clean. At this time, the protective gear is transferred to the second working state for subsequent special treatment.

[0094] Based on this, judging whether to execute the first working state again by the occurrence count can ensure the accuracy of judging whether the protective gear is in a normal state, improve the reliability of the nuclear power plant radioactive protective gear washing system 100, and at the same time, the number of re-cleanings will not be excessive, avoiding unnecessary resource waste.

[0095] It should be noted that the first pollution detection module 110 and the second pollution detection module 150 in the above embodiments can include any one of a scintillation detector, a semiconductor detector, or a neutron detector, etc.

[0096] Combined with any one of the above filtering module 131 and drying module 140, the nuclear power plant radioactive protective gear washing system 100 further includes a noise detection component, and the noise detection component can be electrically connected to the controller. The noise detection component is used to detect the noise value of at least one of the filtering module 131 and the drying module 140. In one example, the noise detection component is used to detect the noise value of the filtering module 131. In another example, the noise detection component is used to detect the noise value of the drying module 140. The control component can issue a warning according to the noise value detected by the noise detection component, so that personnel can timely perform noise reduction processing on the nuclear power plant radioactive protective gear washing system 100 according to the warning. Among them, the warning method can be but is not limited to lighting, popping up windows on external devices, ringing bells, etc.

[0097] As Figure 7 shown, the nuclear power plant radioactive protective gear washing method further includes:

[0098] S01. Obtain the sound pressure level noise value at a preset test distance.

[0099] Optionally, the preset test distance can be but is not limited to 0.5 m, 1 m, 1.5 m, or 2 m, etc., and can be selected according to different requirements, and will not be limited too much here.

[0100] S02. Obtain the sound power level noise value according to the sound pressure level noise value and the preset test distance.

[0101] S03. Determine whether the sound power level noise value is greater than a preset noise value;

[0102] When the sound power level noise value is greater than the preset noise value, perform step S031: Perform noise reduction processing on at least one of the filtering module 131 and the drying module 140.

[0103] Among them, the methods of noise reduction processing can be, but are not limited to, the following noise reduction methods: (1) Add sound insulation materials such as sound insulation cotton or foam layer to the outer shell or inside of the washing module 120 such as a washing machine or a shoe washing machine to absorb noise. (2) Adjust the washing machine foot pads to ensure that the body is completely level and avoid vibration noise caused by tilting. (3) Place rubber pads, silica gel pads or professional shock-absorbing bases at the bottom of the washing module 120 to reduce the vibration transmission to the ground. There is no further limitation here.

[0104] When the sound power level noise value is less than the preset noise value, perform step S032: Maintain the operating conditions of at least one of the filtering module 131 and the drying module 140.

[0105] In this way, by measuring the noise situation of the nuclear power plant radioactive protection product washing system 100 during use to determine whether noise reduction processing is required, it is beneficial to improve the good use environment and avoid excessive noise pollution. Further, by detecting the sound pressure level noise value and then obtaining the sound power level noise value based on the sound pressure level noise value and the preset test distance, the influence of the test distance on the noise value detection can be avoided, enabling a more intuitive reflection of the noise value during the protection product washing process and reducing the detection error.

[0106] Specifically, in one embodiment, as Figure 8 shown, the above step S01 further includes:

[0107] S011. Select a test plane. Among them, the test plane can be a regular polygon or a circle.

[0108] S012. Obtain the sound pressure level noise value at a preset test distance.

[0109] In this way, measuring the sound pressure level noise value on a regular polygon or circular test plane, since the overall sound pressure distribution of the regular polygon or circle is relatively uniform, it is beneficial to improve the detection accuracy of the sound pressure level noise value, thereby improving the accuracy of the noise reduction operation.

[0110] Combined with any of the above embodiments of the pipeline component 132, refer back to Figure 1, the pipeline component 132 further includes a first recovery pipeline 1323 and a second recovery pipeline 1324, and the switch valve assembly 133 includes a third switch valve 1333 and a fourth switch valve 1334. The first recovery pipeline 1323 is communicatively connected to the first filter 1311 and is disposed near the bottom of the first filter 1311. The second recovery pipeline 1324 is communicatively connected to the second filter 1312 and is disposed near the bottom of the second filter 1312. The third switch valve 1333 is communicatively connected to the first recovery pipeline 1323, and the fourth switch valve 1334 is communicatively connected to the second recovery pipeline 1324.

[0111] It can be understood that when it is necessary to clean the first filter 1311 and the second filter 1312, the first switch valve 1331 and the second switch valve 1332 can be closed, and the third switch valve 1333 and the fourth switch valve 1334 can be opened, so that the cleaning liquid for cleaning the first filter 1311 and the second filter 1312 can be discharged through the first recovery pipeline 1323 and the second recovery pipeline 1324 respectively, thereby preventing the cleaning liquid from contaminating the first pipeline component 1321 and the second pipeline component 1322, and improving the reliability of the radioactive protection article washing system 100 of the nuclear power plant.

[0112] It should be noted that in the above embodiment, after it is determined that the washing module is in the second working state, the protective articles can be placed in the waste treatment system for waste treatment. In addition, the controller in the above embodiment can be, but is not limited to, a device such as a CPU or an MCU that can be electrically connected to the first pollution detection module and the washing module.

[0113] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0114] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "a plurality" appears, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0115] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0116] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath", and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal level than the second feature.

[0117] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.
