[0014] See Figure 1An embodiment of the present invention provides a support device for a radioactive waste liquid treatment system, comprising: a support device body 100, the support device body 100 being divided into a first region 110, a second region 120, and a third region 130; the first region 110 being used for equipment with high radioactivity intensity in the radioactive waste liquid treatment system, the second region 120 being used for equipment with low radioactivity intensity in the radioactive waste liquid treatment system, and the third region 130 being used for equipment without radioactivity in the radioactive waste liquid treatment system; a first spacer 11 being disposed between the first region 110 and the second region 120; and a second spacer 12 being disposed between the second region 120 and the third region 130; wherein the first spacer 11 includes a stainless steel cladding layer and a lead shielding layer, the lead shielding layer being disposed between the stainless steel cladding layers; and the second spacer 12 includes a stainless steel cladding layer and an antistatic and fire-resistant layer, the stainless steel cladding layer being disposed on one side of the second region 120, and the antistatic and fire-resistant layer being disposed on one side of the third region 130. The radioactive waste liquid treatment system in this embodiment of the invention can be a mobile radioactive waste liquid treatment system. The radioactive waste liquid treatment system is installed in a carrier device, which can be moved by a vehicle. Since the radioactive waste liquid treatment system will generate radioactive waste liquid during operation, in order to prevent the radioactive waste liquid from entering the environment, the carrier device body 100 can form a closed space. The radioactive waste liquid treatment system is set in the closed space formed by the carrier device body 100 to achieve isolation from the external environment.

[0015] The radioactive waste liquid treatment system includes various devices, such as evaporators, compressors, preheaters, coolers, condensate tanks, raw liquid tanks, residual liquid tanks, etc. Different devices have different radioactivity of fluids during operation. Therefore, in this embodiment, the enclosed space inside the carrier body 100 is isolated into a first region 110, a second region 120, and a third region 130 by the first spacer 11 and the second spacer 12. According to the different radioactivity of each device, devices with different radioactivity are set in different regions.

[0016] In this embodiment, the first spacer 11 and the second spacer 12 are configured with different structures according to the nature of the equipment contained in each region. Specifically, since the first region 110 contains equipment with high radioactivity, a lead shielding layer is provided inside the first spacer 11 that isolates the first region 110 to shield radiation from the first region 110. The lead shielding layer can be placed between the two stainless steel cladding layers forming the first spacer 11. Since the third region 130 contains non-radioactive equipment, for a mobile radioactive waste liquid treatment system, the non-radioactive equipment can be electrical equipment such as power supply systems and control systems. Therefore, an anti-static and fire-resistant layer is provided on the side of the second spacer 12 located in the third region 130 to prevent accidents such as leakage or fire. Both the first spacer 11 and the second spacer 12 are provided with stainless steel cladding layers on the side of the first region 110 or the second region 120. The stainless steel cladding layers have a certain shielding effect and supporting strength, and have good waterproof performance, which can make the first region 110 and the second region 120 have good containment and prevent radioactive waste liquid from leaking into the environment.

[0017] Meanwhile, since the first area 110, which contains highly radioactive equipment, and the third area 130, which contains the control system, are far apart, when operators are in the third area 130 to control the equipment, the probability of them being exposed to radioactive hazards can be reduced, thus improving the safety of operators when operating the equipment.

[0018] As can be seen, the carrier device of the radioactive waste liquid treatment system provided in the embodiments of the present invention has a reasonable regional division in the carrier device body 100, so that the carrier device can better meet the working requirements of the radioactive waste liquid treatment system.

[0019] See Figure 2 ,exist Figure 2 The diagram shows a schematic of some of the equipment installed inside the carrier device, omitting some of the external structure of the carrier device. In some embodiments, an exhaust filtration system 20 is provided in the first region 110, and one-way pressure valves are provided in the second region 120 and the third region 130; airflow enters the third region 130 from the outside, enters the second region 120 through the one-way pressure valve, and then enters the first region 110 through the one-way pressure valve. The exhaust gas generated by the radioactive waste liquid treatment system enters the exhaust filtration system 20 for treatment.

[0020] Radioactive waste treatment systems generate waste gas during the treatment of radioactive waste. With proper arrangement, this waste gas may be radioactive. Figure 2 . Figure 2The diagram shows the pipe 22 through which the airflow passes from the second region 120 into the first region 110. By setting a one-way air pressure valve and sequentially introducing external airflow into the third region 130, then from the third region 130 into the second region 120, and then from the second region 120 into the first region 110, gas flow in all regions within the carrier body 100 can be ensured, while also preventing exhaust gas in the first region 110 from polluting the second region 120 and the third region 130. Furthermore, compared to directly introducing external airflow into the first region 110, it prevents exhaust gas in the first region 110 from entering the external environment and causing pollution.

[0021] In some embodiments, an air supply duct 21 is provided in the first region 110. The air supply duct 21 is provided with multiple gas inlets 211. The airflow in the first region 110 enters the multiple gas inlets 211 and enters the exhaust filtration system 20 through the air supply duct 21. The exhaust filtration system 20 is configured to process the incoming gas and then discharge it to the outside.

[0022] The air supply duct 21 can extend within the first area 110, and multiple gas inlets 211 can be set along the extension direction of the air supply duct 21. By setting multiple gas inlets 211 on the air supply duct 21, the airflow at different locations in the first area 110 can be processed by the exhaust filtration system 20, thereby increasing the waste gas treatment efficiency.

[0023] See Figure 3 ,exist Figure 3 The diagram shows a schematic of some of the equipment installed inside the carrier device, omitting some of the external structure of the carrier device. In some embodiments, the carrier device also includes a power distribution device 30, which extends through the first region 110, the second region 120 and the third region 130. The power distribution device 30 is configured to be electrically connected to the third region 130, so as to supply power from the third region 130 to the equipment of the radioactive waste liquid treatment system in the second region 120 and the first region 110. The power distribution device 30 passes through the first spacer 11 and is sealed to the first spacer 11.

[0024] The power distribution device 30 distributes power from the power supply system in the third zone 130 to the first zone 110 and the second zone 120, providing power to the equipment in the first zone 110 and the second zone 120. When the power distribution device 30 extends from the second zone 120 to the first zone 110, it needs to pass through the first spacer 11. Since there is exhaust gas in the first zone 110, in order to prevent exhaust gas from polluting the second zone 120 and the third zone 130, the position where the power distribution device 30 passes through the first spacer 11 can be sealed, that is, the power distribution device 30 is sealed to the first spacer 11.

[0025] See Figure 4In some embodiments, the first region 110 and the second region 120 are respectively provided with waste liquid collection ports, which are used to collect waste liquid from the first region 110 and the second region 120.

[0026] Radioactive waste liquid treatment systems may experience leaks during operation. To collect leaked waste liquid, waste liquid collection ports are installed in both Zone 110 and Zone 120. For example... Figure 4 As shown, a first waste liquid collection port 41 can be provided in the first region 110, and a second waste liquid collection port 42 can be provided in the second region 120. The first waste liquid collection port 41 and the second waste liquid collection port 42 can both be provided close to the first spacer 11. This allows the first waste liquid collection port 41 and the second waste liquid collection port 42 to be connected to an external waste liquid collection device at the same time. The waste liquid in the first region 110 and the second region 120 can be conveniently collected by the external waste liquid collection device, avoiding the accumulation of waste liquid in the first region 110 or the second region 120.

[0027] In some embodiments, different radioactive monitoring devices are installed in the first area 110 and the second area 120. These different devices monitor the radioactivity levels in both areas and issue warnings based on the varying monitoring levels. Since the first area 110 and the second area 120 contain equipment with different radioactivity levels and have different requirements for radioactivity levels, the required radioactivity levels for warning in both areas are also different. Therefore, by installing different radioactive monitoring devices in the first area 110 and the second area 120 respectively, and detecting the radioactivity levels in both areas, warnings are issued when radioactivity levels are abnormal to prevent accidents.

[0028] In some embodiments, a smoke monitoring device is installed in the third zone 130. As described above, electrical equipment such as power supply systems and control systems are installed in the third zone 130, which is prone to fire accidents. Therefore, a smoke monitoring device is installed in the third zone 130 to prevent fire accidents from occurring.

[0029] In some embodiments, two inlets / outlets are provided in the first region 110 and the second region 120, and one inlet / outlet is provided in the third region 130. Understandably, the first region 110 and the second region 120 are used to install the process equipment of the radioactive waste liquid treatment system. Due to the large number and size of the installed equipment, two inlets / outlets are provided in the first region 110 and the second region 120 to facilitate the disassembly and installation of the equipment; the third region 130 is used to accommodate smaller electrical equipment, therefore only one inlet / outlet is provided.

[0030] In some embodiments, waste liquid blocking sections are provided at the inlet and outlet of the first region 110 and the second region 120. The first region 110 and the second region 120 may contain leaked radioactive waste liquid. Since the inlet and outlet are not sealed, radioactive waste liquid may flow into the external environment from the inlet and outlet. Therefore, by providing waste liquid blocking sections at the inlet and outlet of the first region 110 and the second region 120, when the liquid level of the radioactive waste liquid in the first region 110 and the second region 120 is lower than the height of the waste liquid blocking section, the flow of radioactive waste liquid into the external environment can be prevented.

[0031] In some embodiments, a raw liquid inlet, a treated liquid outlet, a raw liquid sampling port, and a treated liquid sampling port are provided in the first region 110. A raw liquid tank is located in the first region 110. Radioactive waste liquid enters the raw liquid tank of the first region 110 through the raw liquid inlet. The treated liquid is recycled through the treated liquid outlet. The raw liquid sampling port and the treated liquid sampling port are used to monitor the radioactivity of the raw liquid and the treated liquid, respectively.

[0032] In some embodiments, a condensate outlet and a cooling water inlet / outlet are provided in the second region 120. The second region 120 is equipped with structures such as a cooler and a condensate tank, so setting the condensate outlet and the cooling water inlet / outlet in the second region 120 facilitates connection with the aforementioned equipment.

[0033] In some embodiments, an operating device access port and an external power input port are provided in the third region 130. Electrical equipment is provided in the third region 130, and can be easily connected to the electrical equipment in the third region 130 through the operating device access port and the external power input port.

[0034] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0035] The above are merely embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
