Description

Technical Field

[0001] The invention particularly relates to a glass solidification feeding device and a glass solidification melting furnace. Background Art

[0002] In recent years, the glass solidification process has been widely used to treat radioactive liquids. The glass solidification process first pre-treats the radioactive liquid through calcination to convert it into an oxide, and then mixes it with a glass substrate in a certain proportion in a calcination furnace, melts it, and pours it. After annealing, the radioactive nuclides are fixed in the glass network to form a stable glass solid body.

[0003] However, currently, when radioactive liquid and glass beads enter the furnace, they are mixed and flowed into the furnace through pipes such as feed pipes. The temperature inside the furnace is relatively high, causing the glass beads to melt earlier in the pipe. Premature melting will mainly lead to blockage of the feed pipe. The radioactive environment makes it difficult to replace the feed pipe. Therefore, the current glass solidification process feed pipe has problems such as liquid evaporation, softening of glass beads, and affecting the normal operation of the furnace.

[0009] Furthermore, the second feed pipe also includes a sealing plug, a ring groove is opened on the side of the sealing plug, and a buckle is provided at the second pipe mouth. The sealing plug is axially embedded in the second pipe mouth, and the buckle is radially penetrated into the second pipe mouth and clamped in the ring groove to fix the axial position of the sealing plug.

[0010] Furthermore, a sealing ring is provided on the portion of the sealing plug embedded in the second pipe opening, which is used to seal the gap between the sealing plug and the second pipe opening.

[0011] Furthermore, a handle is provided on the sealing plug, and the handle serves as a lifting ear on the second feeding pipe.

[0012] Furthermore, the jacket includes a cylinder, a liquid inlet pipe and a liquid return pipe. The cylinder is sleeved on the outside of the feed pipe and has a cavity inside. The liquid inlet pipe and the liquid return pipe are both connected to the liquid supply device and are both connected to the cavity in the cylinder.

[0025] Example 1

[0026] like Figure 1 As shown, the glass solidification feeding device of this embodiment is mainly used in nuclear industrial plants, and includes a feeding pipe 1 and a jacket 3. The feeding pipe 1 is installed on the feeding port of the furnace, runs through the furnace, and one end is connected to the feeding equipment, and the other end is connected to the inside of the furnace for feeding into the furnace. The jacket 3 is sleeved on the outside of the feeding pipe 1 and is located on the pipe section of the feeding pipe 1 inside the furnace. A cavity is provided inside the jacket 3 for circulating cooling liquid to liquid-cool the feeding pipe 1.

[0027] The glass solidification feeding device of this embodiment, by arranging a jacket 3 on the outside of the feed pipe 1, uses liquid cooling heat exchange to prevent the glass beads from melting inside the feed pipe 1 and prevent the glass beads from softening at high temperatures. At the same time, it can also prevent the high-temperature liquid from evaporating and evaporating and crystallizing at the feed pipe, thereby ensuring that the furnace can be fed smoothly and avoiding affecting the normal operation of the furnace.

[0028] And because the feed pipe 1 passes through the feed port of the furnace and connects the inside and outside of the furnace, the section of the feed pipe 1 inside the furnace is bound to be heated more severely. In this embodiment, the jacket 3 is arranged on the section of the feed pipe 1 inside the furnace, that is, the section of the feed pipe 1 that is most heated, so that liquid cooling can achieve the best effect.

[0029] In this embodiment, the feed pipe 1 includes a first feed pipe 11 and a second feed pipe 12, and the first feed pipe 11 and the second feed pipe 12 are used for feeding radioactive liquid and glass beads respectively, that is, the two materials are fed through different pipes respectively. Compared with the conventional mixed feeding method, this feeding method can realize feeding control separately, and the process control is more convenient. It can also ensure that the liquid and glass beads are fed at the same time to ensure a better melting state. Specifically, the diameter of the first feed pipe 11 is DN20~DN40, and the diameter of the second feed pipe 12 is DN20~DN40. The diameter range of the two can ensure that the feeding rate meets the requirements. The fixed flange 2, the pipe mouth flange of the first feed pipe 11 and the pipe mouth flange of the second feed pipe 12 (first pipe mouth 1221) are all truncated cone-shaped, which is convenient for docking with other equipment pipelines. A ball valve can also be set on the first feed pipe 11, and the ball valve has the conditions for opening and closing by remote operation of a power mechanical device.

[0030] Among them, a first pipe opening 1221 and a lifting lug are provided on the pipe section of the second feed pipe 12 outside the furnace. The first pipe opening 1221 is connected to the glass bead feeding equipment, and the lifting lug is used to connect with an external lifting device. Through remote control, the glass solidification feeding device can be lifted and moved to a location such as an operating table for remote operation.

[0031] In this embodiment, the second pipe opening 1211 is also provided on the pipe section of the second feed pipe 12 outside the furnace. The second pipe opening 1211 is a normally closed openable pipe opening. Since the environment is a radioactive environment, it cannot be disassembled during normal operation to prevent the radioactive gas from overflowing. The pipe section of the second feed pipe 12 inside the furnace is provided with a third pipe opening 1212 connected to the inside of the furnace. The second pipe opening 1211 and the third pipe opening 1212 are respectively arranged at the top and bottom ends of a vertical pipe section 121. The first pipe opening 1221 is arranged at the top of a branch pipe 122 extending from the vertical pipe section 121. The bending position between the branch pipe 122 and the vertical pipe section 121 is located on the pipe section of the vertical pipe section 121 outside the furnace. According to the following content, the second pipe opening 1211 is blocked with a lifting ear and a sealing plug. The lifting ear can be disassembled to facilitate the adaptation of different remote operation lifting tools, including power hand tools and manipulator tools, and remote operation can be performed in multiple environments.

[0032] At present, conventional feed pipes are all provided with only one inlet and one outlet, the inlet is connected to the feeding equipment, and the outlet is connected to the furnace. After the second feed pipe 12 adopts the pipe mouth structure of the present embodiment, in this setting structure, the pipe section of the second feed pipe 12 located in the furnace that is most seriously heated is a straight pipe, thereby avoiding the bending structure from affecting the feeding speed of the glass beads, thereby reducing the probability of the glass beads melting in this section; and the second pipe mouth 1211 and the third pipe mouth 1212 are respectively located at the two ends of the vertical pipe section 121, and the lines along the two are vertical straight lines, and the ear is set At the second pipe opening 1211, the lifting line of the lifting ear is also in a vertical state, and the lifting is more stable and reliable; and the feed pipeline is set as a bending line, that is, from the first pipe opening 1221 to the third pipe opening 1212, it is necessary to pass through the branch pipe 122, the bending position and the vertical pipe section 121 in sequence. This layout can avoid interference between the feeding equipment and the lifting equipment. At the same time, since the bending position is located on the pipe section outside the furnace, the bending position is located in a pipe section with better heating conditions, thereby avoiding further heating and melting of the glass beads when they are decelerated after the bend.

[0033] In this embodiment, Figure 2As shown, the second feed pipe 12 also includes a sealing plug 123, a circular groove 1231 is provided on the side of the sealing plug 123, a buckle 124 is provided at the second pipe opening 1211, the sealing plug 123 is axially embedded in the second pipe opening 1211, and the buckle 124 is radially penetrated into the second pipe opening 1211 and clamped in the circular groove 1231 to fix the axial position of the sealing plug 123. Under normal conditions, the second pipe opening 1211 is normally blocked by the sealing plug, and the second pipe opening 1211 is opened after the sealing plug is pulled out from the second pipe opening 1211. In other implementations, a cover-like structure with electrically controlled opening and closing can also be used to achieve normal blocking. However, the mechanical blocking structure in this embodiment is more suitable for the field of radioactive liquid glass solidification in a radioactive environment.

[0034] In this embodiment, a handle 1233 is provided on the sealing plug 123, and the handle 1233 is used as a lifting ear on the second feed pipe 12, and is used for remote lifting operation by a lifting device. The radioactive liquid glass solidification process environment has a certain radioactivity. Since this embodiment can use a lifting device for remote operation, it can be applicable to the radioactive liquid glass solidification process. When the lifting ear interface of the device needs to be replaced, the buckle 124 is first pulled out radially of the second pipe mouth 1211, and then the sealing plug 123 can be pulled out axially of the second pipe mouth 1211 by the lifting device, and then replaced. (Plugging and unplugging are not allowed during normal process operation to prevent the overflow of radioactive gas, and it only plays a role of remote lifting and sealing).

[0035] In this embodiment, the portion of the sealing plug 123 embedded in the second pipe opening 1211 is provided with a sealing ring 1232 for sealing the gap between the sealing plug 123 and the second pipe opening 1211, thereby preventing external impurities from entering the furnace or radioactive gases generated by the furnace from overflowing.

[0036] In this embodiment, the jacket 3 includes a barrel 31, a liquid inlet pipe 32 and a liquid return pipe 33. The barrel 31 is sleeved on the outside of the feed pipe 1 and has a cavity inside. The liquid inlet pipe 32 and the liquid return pipe 33 are both connected to the liquid supply device, and the pipe mouth of the liquid inlet pipe 32 is located at one end of the barrel 31 facing the inside of the furnace, and the pipe mouth of the liquid return pipe 33 is located at one end of the barrel 31 away from the inside of the furnace, ensuring that the colder cooling liquid first enters the higher temperature position through the liquid inlet pipe 32, and continuously exchanges heat and gradually heats up in the process of flowing to the lower temperature position, and finally flows out of the barrel 31 through the liquid return pipe 33. The cooling liquid used in this embodiment is water.

[0037] In this embodiment, a fixing plate 311 is provided inside the cylinder 31, and the fixing plate 311 is connected between the inner wall of the cylinder 31 and the outer wall of the feed pipe 1, and is used to fix the relative positions of the feed pipe 1 and the cylinder 31, so that the pipe section of the feed pipe 1 located in the cylinder 31 is always kept in a vertical state, thereby forming a one-way flow channel for cooling water, ensuring that the material falls into the furnace smoothly.

[0038] In this embodiment, the area above the fixed plate 311 in the cylinder 31 is specifically called the water inlet pipe water cooling zone, and the area below the fixed plate 311 is called the main water cooling zone. Electron beam welding can be used between the two water cooling zones in the cylinder 31, with a small heat affected zone and small welding deformation.

[0039] A through hole connecting the two areas is provided on the fixed plate 311, and the liquid inlet pipe 32 is connected to the main water cooling zone. This arrangement further ensures that the cooling water enters from the bottom and exits from the top, avoiding the mixing of higher temperature cooling water with the lower temperature cooling water that has just entered the main water cooling zone, and is used to form a one-way flow channel for cooling water, which has a better cooling effect.

[0040] In this embodiment, the device further includes a fixed flange 2, and the feed pipe 1 is installed on the feed port of the furnace through the fixed flange 2. The fixed flange 2 includes a flange 21 and a fastener 22. The flange 21 is arranged in the middle of the feed pipe 1, and the fastener 22 is movably arranged on the flange 21, and is used to connect the flange 21 and the feed port of the furnace. In this embodiment, the fastener 22 can be a guide pin and a bolt, which are used for guiding and fixing when the feed device is installed remotely, and the bolt is a structure that can be replaced remotely.

[0041] The liquid inlet pipe 32 and the liquid return pipe 33 are both connected to the cavity in the cylinder 31 after passing through the flange sheet 21 of the fixed flange 2. A through hole connected to the cavity in the cylinder 31 is provided on the fixed flange 2 to facilitate the penetration and fixation of the liquid inlet pipe 32 and the liquid return pipe 33. The pipe opening of the liquid return pipe 33 is only arranged in the middle part of the fixed flange 2 in the thickness direction, and is connected to the cavity in the cylinder 31 through the through hole on the fixed flange 2.

[0042] In general, the feeding device of this embodiment belongs to the technical field of supplying radioactive liquid and glass beads into a furnace, and specifically relates to a device for supplying radioactive liquid and glass beads into a furnace.

[0043] The device sets a jacket 3 on the outside of the feed pipe 1 (including the first feed pipe 11 of the radioactive liquid and the second feed pipe 12 of the glass beads) to cool the feed pipe 1, which can prevent the high-temperature liquid from evaporating and crystallizing, and prevent the glass from softening. The second pipe opening 1211 set on the second feed pipe 12 is sealed with a sealing plug 123. The sealing plug 123 is also provided with a handle 1233 for plugging and unplugging operations. The fixed flange 2 is provided with fasteners, so that the sealing plug 123 and the fixed flange 2 can be used for remote disassembly and assembly. The jacket 2 can prevent the glass beads from clogging the feed pipe 1, so a corrosion-resistant alloy is selected, which has excellent high-temperature corrosion resistance. At the same time, the jacket 2 adopts the electron beam welding method, and the welding deformation is small.

[0044] In this embodiment, each component of the device can be made of corrosion-resistant alloy to ensure excellent high-temperature corrosion resistance, and the specific material can be nickel-based alloy, inconel 690. The device has a simple structure, can meet the requirements of long-distance disassembly and assembly in the hot chamber, and is suitable for feeding radioactive waste liquid.

[0045] In the existing conventional scheme, when the radioactive liquid and glass beads are transported to the furnace through the feed pipe 1, the temperature of the furnace air chamber is too high, which can easily lead to the softening of the glass beads and the evaporation and crystallization of the liquid, affecting the normal operation of the furnace. However, the feed device of this embodiment can pass cooling water through the jacket 3 to reduce the temperature of the feed pipe 1 and prevent blockage. This embodiment specifically uses 20°C cooling water, which enters the jacket 3 through the cooling water inlet pipe 32. When the cooling water is 20°C, after heat exchange calculation, the temperature of the feed pipe 1 can ensure that the glass beads are not softened. If the cooling water temperature is too high or too low, it will affect the design parameters of the jacket 3, thereby affecting the normal operation of the equipment.

[0046] The device of this embodiment can also be installed and disassembled remotely. After the device is retired, the feeding device can be disassembled and assembled remotely by a power mechanical device such as a lifting tool because it is also provided with a sealing plug 123. The guide pins provided on the fixed flange 2 can provide guidance during remote disassembly and assembly, and then the fixed connection of the fixed flange 3 can be achieved by bolts.

[0047] In addition, in this embodiment, a first quick connector 321 and a second quick connector 331 may be provided on the cooling water inlet pipe 32 and the cooling water return pipe 33, respectively. During remote disassembly and assembly, the first quick connector 321 and the second quick connector 331 may be removed by a power mechanical device to complete remote disassembly and assembly of the feeding device.

The glass solidification feeding device is installed at the feeding port of the furnace body so as to connect the feeding equipment through the glass solidification feeding device to realize feeding.

[0050] During the feeding process, liquid cooling is achieved through the jacket 3 of the feeding device to prevent the glass beads from melting in the feeding pipe 1 and to prevent the high-temperature liquid from evaporating, thereby affecting the normal operation of the process.

[0051] The feeding device of the furnace of this embodiment can also be installed and disassembled remotely. The feeding device is also provided with a sealing plug 123, which can be disassembled and assembled remotely by a power mechanical device such as a lifting tool. The power mechanical tool cooperates with the handle to complete the lifting and transportation of the feeding pipe. The cooling water inlet pipe 32 and the cooling water return pipe 33 are respectively provided with a first quick connector 321 and a second quick connector 331. When disassembling and assembling remotely, the first quick connector 321 and the second quick connector 331 are removed by a power mechanical device to complete the disassembly and assembly of the feeding device remotely. The guide pin provided on the fixed flange 2 can be used for guidance during remote disassembly and assembly, and then the fixed connection of the fixed flange 3 is achieved by bolts.
