Description

Technical Field

[0001] The present invention relates to the field of radioactive waste treatment, and more particularly to a waste filter element integrated volume reduction device and process. Background Art

[0002] Waste filter cartridges generated by nuclear facilities typically consist of a frame, filter media, and seals, leaving numerous voids within the filter cartridges. High-dose waste filter cartridges generated by nuclear facilities are typically disposed of using cement curing or polyethylene HIC (cross-linked high-density polyethylene high-integrity containers). Neither of these methods reduces the volume of high-dose rate waste filters, resulting in increased waste volume. Currently, no volume reduction measures are in place for high-dose rate waste filter cartridges generated by domestic nuclear facilities.

[0003] The cement solidification disposal solution involves using a filter element replacement device with a shielding function to remove the filter element from the filter. The replacement device is then lifted by a crane and the individual filter elements are released remotely into a steel drum. Depending on the size of the filter element, a filter element holder is pre-installed in the steel drum to position the filter element. After the steel drum receives the spent filter element, it is transported to a specific location via a conveyor system (such as a roller conveyor) for remote cement grouting to seal the spent filter element in the container. Because the volume of the steel drum is usually larger than the size of the spent filter element, directly cementing a single high-dose rate spent filter element in the steel drum increases the volume of the spent filter element, failing to reduce its volume.

[0004] The polyethylene HIC disposal solution involves using a shielded filter element replacement device to remove the filter element from the filter. The replacement device is then lifted by a crane and remotely released into a polyethylene HIC (with an external shielded container). The polyethylene HIC container can hold multiple spent filter elements. Once full, the container's contents undergo multiple dehydration cycles to ensure that the free water content is less than 1%. After dehydration, the container is capped, completing the disposal of spent filter elements. Although the polyethylene HIC packs multiple filter elements to a certain extent, it still increases the volume of spent filter elements. Summary of the Invention

[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0035] like Figures 1 to 10 As shown, the integrated waste filter element volume reduction device in some embodiments of the present invention can be used to compact and reduce the volume of waste filter elements generated during the operation of a nuclear power plant. The integrated waste filter element volume reduction device includes a lifting mechanism 1, a transfer mechanism 2, and a compression mechanism 3. The transfer mechanism 2 includes a compaction barrel 21 and a shielding chamber 22.

[0036] The compacting barrel 21 consists of a barrel cover 211 and a barrel body 212. The barrel cover 211 is installed on the barrel body 212. The compacting barrel 21 is used to load waste filter elements to prevent pollution to other equipment during the process of reducing the volume of the waste filter elements. "Volume reduction" means reducing the volume of the waste filter elements. The lifting mechanism 1 is used to transport the compacting barrel 21 containing the waste filter elements into the shielding cavity 22. The compression mechanism 3 is used to compress the compacting barrel 21 in the shielding cavity 22. During this process, the compacting barrel 21 containing the waste filter elements is compressed into a barrel cake to reduce the volume of the waste filter elements.

[0037] This volume reduction device can compact and reduce the volume of waste filter elements, compressing the volume of the waste filter elements, fully implementing the principle of waste minimization, and being more conducive to environmental protection. At the same time, this volume reduction device is provided with a shielding structure to achieve radiation protection for personnel and the environment, reducing the radioactive hazards of waste filter elements to personnel and the environment during transportation and volume reduction, and is suitable for various types of nuclear facilities.

[0038] like Figures 1 to 4 As shown, in some embodiments, the lifting mechanism 1 includes a shielding container 11 and a lifting piece 12, and the shielding container 11 is movably connected to the lifting piece 12. The shielding container 11 is used to load and transport the compacted barrel 21 containing the waste filter element, and at the same time shield the radioactivity of the waste filter element to achieve the safe transportation of the compacted barrel 21 containing the waste filter element. The shielding container 11 includes a shielding body 111, and the top of the shielding body 111 includes an openable shielding cover 113. The shielding cover 113 is provided with a grabbing mechanism 1131 that can grab and release the barrel cover 211, which is used to separate the barrel cover 211 from the barrel body 212 to place the waste filter element into the barrel body 212.

[0039] Two or more shielding bottom plates 112 are provided at the bottom of the shielding body 111 for loading and releasing waste filter elements. The shielding bottom plates 112 can be close to or away from each other. When the shielding bottom plates 112 are away from each other, the bottom of the shielding body 111 is opened and the shielding container 11 is released into the shielding cavity 22. When the shielding bottom plates 112 are close to each other, the bottom of the shielding body 111 is closed. At this time, the shielding body 111 can load and transport the shielding container 11.

[0040] In other embodiments, a shielding bottom plate 112 is further provided at the bottom of the shielding container 11 for loading and releasing waste filter elements. The shielding bottom plate 112 moves laterally along the shielding body 111 to control the opening or closing of the bottom of the shielding container 11. When the bottom of the shielding body 111 is opened, the shielding container 11 is released into the shielding cavity 22, and the bottom of the shielding body 111 is closed. At this time, the shielding body 111 can load and transport the shielding container 11.

[0041] Furthermore, the shielding container 11 is made of steel plates or other materials with shielding effects, and is used to shield the radioactivity of the waste filter element and prevent the radioactivity of the waste filter element from spreading to the outside during transportation.

[0042] The lifting component 12 includes a cantilever crane 121, which includes a rotating support column 1211, a beam 1212 and a lifting component 1213. The rotating support column 1211 is connected to the beam 1212 so that the beam 1212 can rotate. The lifting component 1213 is movably connected to the beam 1212 so that the lifting component 1213 can move freely on the beam 1212 to realize the lifting and translation of the shielding container 11. When the lifting structure transports the shielding container 11, the lifting component 1213 lifts the shielding container 11 and lifts the shielding container 11 onto the shielding cavity 22.

[0043] In some embodiments, the transfer mechanism 2 also includes a transfer component 23 arranged in the shielding cavity 22. The upper side of the shielding cavity 22 is provided with a first opening 221 for the compaction barrel 21 to pass through and enter the shielding cavity 22. The compaction barrel 21 in the shielding container 11 is received by the transfer component 23 after the shielding bottom plate 112 is opened. The transfer component 23 receives the compaction barrel 21 and then transfers it.

[0044] The transfer component 23 includes a lifting plate 231 and a clamp 232. The lifting plate 231 and the clamp 232 are arranged in the shielding cavity. The lifting plate 231 is a lifting electric drive design for receiving the compacting barrel 21 released from the shielding container 11. At this time, the longitudinal section length of the compacting barrel 21 is greater than the longitudinal section length of the lifting plate 231, but the longitudinal section length of the compacting barrel 21 is less than the longitudinal section length of the first opening 221, so that the compacting barrel 21 and the lifting plate 231 can both pass through the first opening 221, and the shielding bottom plate 112 can be partially opened to prevent the compacting barrel 21 from falling from the shielding container 11 while allowing the lifting plate 231 to rise, so that the lifting plate 231 contacts the bottom of the compacting barrel 21, receives the compacting barrel 21, and then fully opens the shielding bottom plate 112 to allow the compacting barrel 21 to rise together with the lifting plate 231.

[0045] When transferring the compacting barrel 21 into the shielding chamber 22, the shielding bottom plate 112 is first partially opened to prevent the compacting barrel 21 from falling, while allowing the lifting plate 231 to pass through the opening formed after the shielding bottom plate 112 is opened. Then the lifting plate 231 rises and contacts the bottom of the compacting barrel 21. At this time, the shielding bottom plate 112 is fully opened to allow the compacting barrel 21 to descend along with the lifting plate 231. A detection device is provided on the lifting plate 231 to determine whether the compacting barrel 21 has taken over the compacting barrel 21. After the detection device detects the compacting barrel 21, the lifting plate 231 descends together with the compacting barrel 21 to a specific position in the shielding chamber 22, so that the compacting barrel 21 completely enters the shielding chamber 22, waiting to be grasped and transferred by the clamp 232.

[0046] The clamp 232 is a mobile electric drive design with clamping, releasing and moving transmission functions. It can clamp the compacting barrel 21 while transmitting the compacting barrel 21 inside the shielding cavity 22, and release the compacting barrel 21 after reaching the designated position.

[0047] In some embodiments, a second opening 222 is further provided on the upper side of the shielding cavity 22, and the compression mechanism 3 includes a compactor 31 arranged above the second opening 222. When the clamp 232 moves the compacting barrel 21 to the bottom of the second opening 222, the compactor 31 compresses the compacting barrel 21, and the compacting barrel 21 is compressed into a barrel cake, thereby compacting the waste filter element in the barrel 21 to reduce its volume.

[0048] Furthermore, the compactor 31 is provided with a sleeve 311, which is used to position the compacting barrel 21 and limit the size of the barrel cake during the compaction process. Sleeve 311 has sufficient strength to prevent the barrel from expanding and damaging it during the compaction process. The inner wall of sleeve 311 is smooth to prevent the waste filter element from remaining in sleeve 311 after volume reduction. The internal dimensions of sleeve 311 are set within a reasonable range to limit the outer diameter of the barrel cake and prevent the size of the barrel cake from exceeding the requirements for subsequent processing. The pressure head of the compactor 31 cooperates with sleeve 311 to squeeze the barrel cake out of sleeve 311, making it easier for the barrel cake to escape from sleeve 311. At the same time, the pressure head effectively compacts the compacting barrel 21 to prevent the barrel cake from rebounding.

[0049] It can be understood that after the compacting barrel 21 is compressed into a barrel cake by the compression mechanism 3, the clamp 232 can move the barrel cake from the compression position and move it to a position for subsequent processing. At the same time, the clamp 232 can be manually set as needed. In the event of a system failure, the compacting barrel 21 and the barrel cake can be transferred by manual control.

[0050] In some embodiments, the lower side of the shielding cavity 22 is also provided with a third opening 223 for the compressed compacting barrel 21 to pass through and leave the shielding cavity 22. A storage mechanism 4 for storing the compressed compacting barrel 21 is provided below the third opening 223. The clamp 232 moves the barrel cake to above the third opening 223, and then the clamp 232 is released, and the barrel cake passes through the third opening 223 and is released into the storage mechanism 4. The storage mechanism 4 is a barrel-shaped structure, and the outer shell of the storage mechanism 4 is made of steel or other materials with shielding effect, which is used to shield the radioactivity of the waste filter element and prevent the waste filter element from radiating to the outside world.

[0051] In other embodiments, the storage mechanism 4 is a concrete container. After the waste filter elements fill the storage mechanism 4, cement grouting is performed into the storage mechanism 4 to seal the waste filter elements in the container, shielding the radioactivity of the waste filter elements and preventing the waste filter elements from radiating to the outside.

[0052] Preferably, in some embodiments, an entrance shielding plate 24 is provided on the upper side of the first opening 221. The entrance shielding plate 24 is two or more movable plates that can move closer to or away from each other, and is used to control the opening and closing of the first opening 221. The entrance shielding plate 24 is driven by a motor. When the crane lifts the shielding container 11 onto the entrance shielding plate 24, the two movable plates of the entrance shielding plate 24 are movably connected to the two shielding bottom plates 112 respectively, so that the entrance shielding plate 24 can drive the shielding bottom plates 112 to move. The motor drives the entrance shielding plates 24 away from each other, the first opening 221 opens, and at the same time drives the shielding bottom plates 112 away from each other, and the bottom of the shielding container 11 opens.

[0053] When the compacting barrel 21 needs to be transferred to the shielding chamber 22, first the first opening 221 and the shielding bottom plate 112 are partially opened to ensure that the compacting barrel 21 will not fall from the shielding container 11, and then the lifting plate 231 rises and contacts the bottom of the compacting barrel 21 through the first opening 221. At this time, the detection device detects that the lifting plate 231 has taken over the compacting barrel 21, and then the lifting plate 231 and the compacting barrel 21 descend together, so that the lifting plate 231 can transfer the compacting barrel 21 to the shielding chamber 22. When the compacting barrel 21 and the lifting plate 231 are both located in the shielding chamber 22, the motor drives the inlet shielding plate 24 to approach each other, the first opening 221 is closed, and at the same time drives the shielding bottom plate 112 to approach each other, and the bottom plate of the shielding container 11 is closed.

[0054] In other embodiments, the inlet shielding plate 24 is a movable plate that moves laterally along the first opening 221 to control the opening and closing of the first opening 221. The inlet shielding plate 24 is driven by a motor. When the crane lifts the shielding container 11 onto the inlet shielding plate 24, the movable plate of the inlet shielding plate 24 is movably connected to the shielding bottom plate 112 so that the inlet shielding plate 24 can drive the shielding bottom plate 112 to move. The motor drives the inlet shielding plate 24 to move out of the upper side of the first opening 221, and the first opening 221 opens, while driving the shielding bottom plate 112 to move, and the bottom of the shielding container 11 opens.

[0055] When the compacting barrel 21 needs to be transferred to the shielding chamber 22, first the first opening 221 and the shielding bottom plate 112 are moved sideways along the first opening 211 to ensure that the compacting barrel 21 will not fall out of the shielding container 11, and then the lifting plate 231 rises and contacts the bottom of the compacting barrel 21 through the first opening 221. At this time, the detection device detects that the lifting plate 231 has taken over the compacting barrel 21, and then the lifting plate 231 and the compacting barrel 21 descend together, so that the lifting plate 231 can transfer the compacting barrel 21 to the shielding chamber 22. When the compacting barrel 21 and the lifting plate 231 are both located in the shielding chamber 22, the motor drives the inlet shielding plate 24 to move to the upper side of the first opening 221, and the first opening 221 is closed, driving the shielding bottom plate 112 to move, and the bottom plate of the shielding container 11 is closed.

[0056] Preferably, in some embodiments, an outlet shielding plate 25 is provided on the lower side of the third opening 223 for controlling the opening and closing of the third opening 223. The outlet shielding plate 25 is two or more movable plates that can move closer to or away from each other. The outlet shielding plate 25 is driven by a motor. When the motor drives the outlet shielding plates 25 away from each other, the third opening 223 opens, the clamp 232 releases the barrel cake, and then the barrel cake falls into the storage device. The motor drives the outlet shielding plates 25 closer to each other, and the third opening 223 is closed.

[0057] In other embodiments, the outlet shielding plate 25 is a movable plate that moves laterally along the third opening 223. The outlet shielding plate 25 is driven by a motor. When the outlet shielding plate 25 moves out from the lower side of the third opening 223, the third opening 223 opens, and the clamp 232 releases the barrel cake, which then falls into the storage structure 4. Then, the outlet shielding plate 25 moves into the lower side of the third opening 223, and the third opening 223 is closed.

[0058] The present application also provides a process for integrated volume reduction of waste filter elements, comprising the following steps:

[0059] S1, loading the waste filter element into the compacting barrel 21;

[0060] S2, the lifting mechanism 1 and the transfer mechanism 2 transport the compacting barrel 21 into the shielding chamber 22;

[0061] S3 , the compression mechanism 3 compresses the compacting barrel 21 in the shielding chamber 22 to reduce the volume of the waste filter element in the compacting barrel 21 .

[0062] Specifically, if Figure 1 、 Figures 5 to 10 As shown, in step S2, the lifting mechanism 1 includes a cantilever crane 121 and a shielding container 11. First, the shielding container 11 is equipped with a compaction barrel 21, which is transported to the integrated volume reduction device by other equipment. The shielding container 11 is lifted by the cantilever crane 121, and then the shielding container 11 is lifted onto the inlet shielding plate 24 above the shielding cavity 22.

[0063] After the shielding container 11 is hoisted onto the inlet shielding plate 24, the inlet shielding plate 24 is docked and installed with the shielding bottom plate 112 of the shielding container 11, and then the motor drives the inlet shielding plate 24 to move, driving the shielding bottom plate 112 to move. When the compacting barrel 21 is transferred from the shielding container 11 to the shielding cavity 22, first, the first openings 221 at the bottom of the shielding container 11 and the upper side of the shielding cavity 22 are partially opened to ensure that the compacting barrel 21 will not fall from the shielding container 11. At the same time, the lifting plate 231 rises, passes through the first opening 221 and contacts the bottom of the compacting barrel 21, and then the first openings 221 at the bottom of the shielding container 11 and the upper side of the shielding cavity 22 are fully opened, the compacting barrel 21 leaves the shielding container 11, and passes through the first opening 221 together with the lifting plate 231. The compacting barrel 21 and the lifting plate 231 descend into the shielding cavity 22 together, and then the first openings 221 at the bottom of the shielding container 11 and the upper side of the shielding cavity 22 are closed.

[0064] The transfer mechanism 2 includes a lifting plate 231 and a clamp 232 arranged in the shielding cavity 22. The lifting plate 231 receives the compacting barrel 21, and then the lifting plate 231 and the compacting barrel 21 are lowered to the designated position in the shielding cavity 22. Then the clamp 232 clamps the compacting barrel 21 and moves it to the bottom of the compression mechanism 3 to carry out the next step of reducing the volume of the compacting barrel 21. The lifting plate 231 returns to its original position after the compacting barrel 21 is removed.

[0065] In step S3, the compression mechanism includes a compactor 31 arranged above the second opening 222 on the upper side of the shielding cavity 22. The compactor 31 is also provided with a liftable sleeve 311. After the compacting barrel 21 is moved to the bottom of the compactor 31 by the clamp 232, the clamp 232 releases the compacting barrel 21 and moves away to prevent the clamp 232 from being damaged by the compactor 31. At this time, the compacting barrel 21 is placed under the compactor 31, and then the sleeve 311 of the compactor 31 falls and sleeves the compacting barrel 21, thereby positioning the compacting barrel 21 and aligning the pressure head of the compactor 31 with the compacting barrel 21, so that the volume reduction process is faster.

[0066] When the sleeve 311 completely covers the compacting barrel 21 and completes the positioning of the compacting barrel 21, the pressure head of the compactor 31 drops, and the compacting barrel 21 is compressed by pressure. After the compression is completed, the compacting barrel 21 becomes a barrel cake, and the pressure head of the compactor 31 and the sleeve 311 of the compactor 31 return to their original positions. The clamp 232 moves to the position of the barrel cake, re-clamps the barrel cake and moves it to above the third opening 223 on the lower side of the shielding cavity 22. Finally, the outlet shielding plate 25 moves, and the third opening 223 is opened. Then the clamp 232 releases the barrel cake, and the barrel cake falls into the storage mechanism 4 through the third opening 223.

[0067] It can be understood that the above technical features can be used in any combination without limitation.

[0068] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
