Description

Technical Field

[0001] The invention relates to the technical field of radioactive waste treatment, in particular to a glass bead substrate blanking system suitable for radioactive waste liquid vitrification. Background Art

[0002] The glass solidification process is one of the main methods for treating radioactive waste liquid. The process principle is to inject radioactive waste liquid and glass bead substrate into the furnace respectively to melt each other to form new glass liquid, and then flow into the container to form a glass solid body, finally realizing the "liquid to solid" process.

[0003] The core equipment of glass solidification technology is the furnace, which usually uses electrode heating. Due to the limited space of the furnace, each batch of waste liquid and glass bead substrate must be accurately measured to the weight / volume required by the formula and added at a certain rate to achieve normal operation of glass solidification. The glass solidification process has high operating costs and limited production capacity, so the smoothness and timeliness of material feeding must be guaranteed; in addition, since the life of the furnace is generally short, the normal operation of the furnace must be guaranteed to the greatest extent within the limited service life. This puts higher requirements on the addition of materials (especially glass bead substrate): once the glass bead substrate is added abnormally, it will directly lead to a formula imbalance in the furnace, which will not only affect the production capacity of the entire process line, but in severe cases it will also increase the difficulty of subsequent processes and maintenance (such as excessive radioactive nuclides in the exhaust gas, accelerated corrosion of furnace refractory bricks, etc.). Therefore, whether the glass bead unloading process is normal or not has a key impact on the overall operation of the glass solidification process.

[0004] However, the current glass bead feeding process has many design risks in maintaining smooth and timely feeding: (1) There is little consideration of the process for removing impurities in glass beads. Since glass beads often introduce impurities such as iron filings, irregular particles, thread ends, and binding tape during the production stage (especially in the production process and packaging process after melting), if these impurities are not completely removed during the production stage and flow into the glass solidification stage, they will have an impact on the entire system. For example, iron filings will increase the current density between the electrodes in the furnace (in severe cases, it will accelerate the corrosion of the electrodes). Irregular particles will block the feeding pipe, causing the glass bead feeding speed to decrease. When the number is large, the pipe will be blocked, causing the feeding to stagnate. (2) The current process controls the feeding speed through a butterfly valve. When there are woven impurities in the glass beads, they are very likely to hang on the butterfly valve. When it reaches a certain level, it will also cause the feeding to be blocked and the furnace to burn out. (3) The current feeding system is a single-line pipeline. When the valve is blocked, the supply of glass bead substrate can only be guaranteed by dismantling the valve, cleaning it, and then reinstalling it to continue feeding. The phenomenon of furnace burning out often occurs.

[0005] Therefore, reasonable processes must be adopted to ensure that the glass curing and unloading system can effectively remove impurities from the glass bead substrate, and to ensure that the material can be unloaded smoothly through the emergency pipeline even after the pipeline is blocked.

[0027] 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.

[0028] The purpose of the present invention is to provide a glass bead substrate unloading system suitable for the glass solidification of radioactive waste liquid, so as to solve the problems existing in the above-mentioned prior art, enhance the removal effect of impurities in the glass bead substrate, and provide a guarantee for the subsequent glass solidification of radioactive waste liquid.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The present invention provides a glass bead substrate unloading system suitable for radioactive waste liquid vitrification, comprising a sorting unit, an impurity removal unit and a discharging unit, wherein the sorting unit is capable of sorting glass beads to screen glass beads within a certain particle size range and remove some impurities; the sorting unit is connected to the impurity removal unit, and the impurity removal unit comprises a conveying and adsorption component 1, which comprises a belt conveyor mechanism 2 and an electromagnet mechanism 3 arranged in the belt conveyor mechanism 2, and the electromagnet mechanism 3 is capable of adsorbing ferromagnetic impurities in the glass beads; the impurity removal unit is connected to the discharging unit, and the glass beads after impurity removal are discharged from the discharging unit.

[0031] The glass bead substrate unloading system suitable for the glass solidification of radioactive liquid waste of the present invention has a sorting unit capable of screening glass beads within a certain particle size range and removing some impurities. The screened glass beads enter the conveying and adsorption assembly 1 of the impurity removal unit. During the process of conveying the glass beads by the belt conveyor mechanism 2, the built-in electromagnet mechanism 3 is capable of adsorbing and removing ferromagnetic impurities in the glass beads. The ferromagnetic impurities in the glass beads are removed during the glass bead conveying process, simplifying the device structure and improving the impurity removal efficiency while ensuring the unloading process. The glass beads after further impurity removal enter the discharging unit and are discharged to the subsequent production process. The glass bead substrate unloading system suitable for the glass solidification of radioactive liquid waste of the present invention has enhanced the impurity removal effect of the glass beads after multiple impurity removal processes, providing convenience and guarantee for the subsequent radioactive liquid waste glass solidification, and ensuring the smooth progress of the radioactive waste glass solidification process.

[0032] It should also be noted that the magnetic induction intensity of the electromagnet mechanism 3 is ≥ 1T to ensure that the electromagnet mechanism 3 can absorb ferromagnetic impurities in the glass beads. Furthermore, the magnetic induction intensity of the electromagnet mechanism 3 is adjustable. In practical applications, the magnetic induction intensity of the electromagnet mechanism 3 can be adjusted according to different working conditions to meet various specific adsorption and impurity removal requirements, thereby ensuring the operational reliability of the electromagnet mechanism 3 and improving the flexibility and adaptability of the conveying and adsorption assembly 1.

[0033] In order to ensure the magnetic induction intensity of the electromagnet mechanism 3, the electromagnet mechanism 3 is connected to a cooling mechanism 4, which is connected to an external cooling medium source to cool the electromagnet mechanism 3. The external cooling medium source delivers cooling medium to the cooling mechanism 4, and the cooling mechanism 4 exchanges heat with the electromagnet mechanism 3 to complete the cooling of the electromagnet mechanism 3, further improving the working reliability of the electromagnet mechanism 3, extending the service life of the electromagnet mechanism 3, and enhancing the impurity removal effect of the conveying adsorption component 1. The cooling medium can be water or other cooling medium, and the cooling mechanism 4 can be a cooling pipe or other cooling structure to accommodate electromagnet mechanisms 3 of various shapes and specifications.

[0034] Specifically, the belt conveyor mechanism 2 is a closed structure to prevent the glass beads from spilling during the conveyance process, which would otherwise waste the glass bead substrate. The belt conveyor mechanism 2 is tilted downward from the feed port to the discharge port. The feed port is connected to the sorting unit. Glass beads of suitable particle size obtained after sorting enter the belt conveyor mechanism 2 through the feed port and are discharged from the discharge port under the action of gravity and enter the subsequent production process. The belt conveyor mechanism 2 includes a conveyor belt. The conveyor belt can be made of an elastic material such as rubber to reduce collisions with the glass beads and effectively protect them. The conveying speed of the conveyor belt can be adjusted by frequency conversion, further improving the flexibility and reliability of material unloading. It should be emphasized that on the side of the conveyor belt close to the inlet and the outlet, the conveyor belt moves from the outlet to the inlet, that is, the conveyor belt adopts a reverse operation mode, and there are protrusions on the conveyor belt. During the reverse operation, some impurities (especially non-spherical granular impurities, such as sand, glass fragments, etc.) are blocked by the protrusions and cannot move toward the outlet, and are then transported by the conveyor belt in the direction away from the outlet, so as to achieve the purpose of blocking impurities. The impurities can be transported to the impurity collector 5 for centralized treatment.

[0035] In this embodiment, the protrusions are angled to better block non-spherical impurities. Furthermore, the angle of the protrusions is smaller than the inclination angle of the belt conveyor 2 to prevent excessive protrusion angles from interfering with the normal conveyance of the glass beads. In practical applications, the protrusions can be block-shaped, spherical, or irregularly shaped. When using spherical or irregularly shaped protrusions, care must be taken to avoid interfering with the falling conveyance of the glass beads.

[0036] More specifically, the number of conveying and adsorption components 1 is multiple groups, and all conveying and adsorption components 1 are arranged in series. In actual applications, multiple levels of conveying and adsorption components 1 can be set according to the impurity removal requirements, and all conveying and adsorption components 1 are arranged in series to further enhance the impurity removal effect. It should also be noted that when multiple groups of conveying and adsorption components 1 are set, the angles of the conveyor belts of all conveying and adsorption components 1 can be gradually changed. Similarly, the specifications of the protrusions can also be gradually changed to remove impurities of different specifications step by step, further enhancing the impurity removal effect of the system, and at the same time improving the flexibility and adaptability of the impurity removal unit.

[0037] At the same time, the impurity removal unit also has an impurity collector 5 for collecting impurities. Ferromagnetic impurities adsorbed by the conveyor adsorption component 1 and impurities blocked by the conveyor belt are all collected in the impurity collector 5 for easy disposal. In other specific embodiments of the present invention, the electromagnet mechanism 3 can be arranged in the sensing area of the belt conveyor mechanism 2. Accordingly, the belt conveyor mechanism 2 has a non-sensing area. When the conveyor belt runs into the sensing area, the electromagnet mechanism 3 adsorbs ferromagnetic impurities in the glass beads onto the conveyor belt. When the conveyor belt runs into the non-sensing area, the adsorbed impurities fall into the impurity collector 5.

[0038] In this specific embodiment, the sorting unit includes a screening machine 6 and an air separation bin 7. The screening machine 6 is used to screen glass beads within a certain particle size range, remove glass beads with too large or too small particle sizes, and obtain glass beads within a certain particle size range; the outlet of the screening machine 6 is connected to the inlet of the air separation bin 7, and an air separation fan 8 is provided in the air separation bin 7. The air outlet of the air separation fan 8 is set toward the impurity outlet of the air separation bin 7, and the screened glass beads enter the air separation bin 7. The air separation fan 8 is set between the inlet and outlet of the air separation bin 7. In the process of the glass beads flowing from the inlet to the outlet of the air separation bin 7, the air separation fan 8 supplies air to the glass beads for blowing, and blows light impurities such as the woven fabric in the glass beads into the impurity recovery bin. In actual application, the impurity outlet of the air separation bin 7 is set to a direction perpendicular to the line connecting the inlet and outlet of the air separation bin 7, so that the air outlet of the air separation fan 8 is directly opposite the impurity outlet, or is tilted toward the inlet direction of the air separation bin 7, so that the light impurities mixed in the glass beads can be blown into the impurity outlet smoothly; it needs to be explained here that the air outlet of the air separation fan 8 can be set to a direction-adjustable structure to adapt to various blowing requirements. Accordingly, the type and working parameters of the air separation fan 8 can be adjusted to enhance the impurity removal effect of the sorting unit and improve the flexibility and adaptability of the sorting unit.

[0039] In addition, the outlet of the air separation bin 7 is connected to the first storage bin 10 by means of a vibrating feeder 9, and the glass beads after air separation enter the first storage bin 10 for temporary storage. The first storage bin 10 is connected to the impurity removal unit by means of a star-shaped feeder 12, thereby ensuring the uniformity of the glass beads and their continuous entry into the impurity removal unit, thereby improving the reliability of the glass beads' transportation and providing a guarantee for the smooth impurity removal by the impurity removal unit. In actual applications, other types of feeders can also be selected according to specific conditions.

[0040] At the same time, the outlet of the impurity removal unit is connected to the second storage bin 11, and the glass beads after impurity removal enter the second storage bin 11 for temporary storage. The second storage bin 11 has a material height sensor to prevent excessive overflow of the glass beads in the second storage bin 11; in order to ensure the accuracy of the discharge, a weighing mechanism 13 is provided at the outlet of the second storage bin 11. The weighing mechanism 13 is used to weigh the discharged glass beads. The weighing mechanism 13 is connected to the discharge unit by a conveyor 14. The weighed glass beads enter the discharge unit, ensuring the accuracy of the discharge and providing convenience for the subsequent radioactive waste liquid glass solidification process.

[0041] In addition, the discharge unit includes a discharge pipe 15, and the impurity removal unit is connected to the furnace 20 via the discharge pipe 15. A butterfly valve 16 is provided on the discharge pipe 15. While discharging, the butterfly valve 16 has a better interception effect on light impurities such as woven fabrics, thereby removing impurities in the glass beads to the maximum extent. In order to avoid the problem that the butterfly valve 16 is blocked by light impurities and causes the glass beads to be discharged in a stagnant manner, thereby affecting the subsequent production process, the discharge pipe 15 is also connected to a branch pipe 17. Both ends of the branch pipe 17 are connected to the discharge pipe 15, and the connection points between the branch pipe 17 and the discharge pipe 15 are respectively located at both ends of the butterfly valve 16. A gate valve 18 is provided on the branch pipe 17. When the main line of the discharge pipe 15 where the butterfly valve 16 is located is blocked, the system will sound an alarm and open the branch pipe 17. The glass beads will enter the furnace 20 through the branch pipe 17 to complete the discharge and ensure the reliability of the glass beads discharge. In actual application, a three-way valve 19 is provided between the discharge pipe 15 and the impurity removal unit. The three-way valve 19 can be used to control the on-off state of the main line of the discharge pipe 15 and the branch pipe 17, thereby improving the working reliability and operation convenience of the discharge unit.

[0042] The glass bead substrate unloading system of the present invention is suitable for the glass solidification of radioactive waste liquid. The sorting unit uses a screening machine 6 to screen glass beads of a certain particle size range. The glass beads enter the air separation bin 7 to remove some light impurities. The screened and impurity-removed glass beads enter the conveying and adsorption component 1 of the impurity removal unit. During the process of conveying the glass beads by the belt conveyor 2, the built-in electromagnet mechanism 3 can adsorb and remove ferromagnetic impurities in the glass beads. The ferromagnetic impurities in the glass beads are removed during the conveying process of the glass beads. At the same time, the conveyor belt adopts a reverse operation mode and uses the protrusions of the conveyor belt to block non-spherical particle impurities. The glass beads are of high quality and have a high impurity removal effect, which improves the impurity removal efficiency while ensuring the unloading process. After further impurity removal, the glass beads are weighed and enter the discharge unit. They are then fed into the furnace 20 through the main line of the unloading pipe 15 where the butterfly valve 16 is located. The butterfly valve 16 can further intercept light impurities such as woven fabrics mixed in the glass beads, thereby removing impurities from the glass beads to the maximum extent. When the main line of the unloading pipe 15 where the butterfly valve 16 is located is blocked, a branch pipe 17 connected in parallel with the butterfly valve 16 can be used for unloading, ensuring that the glass beads can be smoothly fed into the furnace 20, thereby improving the working reliability of the unloading system. The glass bead substrate unloading system suitable for radioactive waste liquid glass solidification of the present invention provides convenience and guarantee for the subsequent radioactive waste liquid glass solidification after multiple impurity removal, ensuring the smooth progress of the radioactive waste liquid glass solidification process.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
