Description

Technical Field

[0001] The present invention relates to the technical field of radioactive pollutant removal, and particularly relates to a movable surface Po-210 pollution treatment device and a test method thereof. Background Art

[0002] During the operation of the fourth-generation advanced fast reactor, the lead-bismuth coolant will generate the extremely toxic radionuclide Po-210 under neutron irradiation conditions. The half-life of Po-210 is 138.4 days, and the specific activity is 1.66×10 14 Bq / g, which decays by emitting 5.30 MeV α particles and also emits 0.001% of 0.803 MeV γ rays. According to the toxicity grouping content of radionuclides in Appendix D of GB18871-2002 "Basic Standards for Ionizing Radiation Protection and Radiation Source Safety", under the condition of equal amounts of various chemical poisons, Po-210 is ranked second in the extremely toxic group.

[0003] At the same time, Po-210 has extremely strong volatility. Once it comes into contact with air, it will form radioactive aerosols, and diffuse and migrate with the random movement of the aerosol suspension particle carriers, attaching and settling on the walls, floors and metal equipment surfaces of the structures in the space of the fourth-generation advanced fast reactor system, ultimately forming radioactive contamination, and it is necessary to reasonably and effectively treat the reactor structure walls, floors and metal equipment.

[0004] Currently, the common radioactive pollution treatment method is that operators enter the decontamination site and use certain physical or chemical decontamination methods to treat the pollution on the surface of the object to be decontaminated, or operators carry pollution treatment devices and mechanical decontamination tools to treat the pollutants on the surface of the object to be decontaminated, which increases the construction risk of the operators and also brings radiation safety risks to the operators, having certain limitations and risks. Summary of the Invention

[0005] Aiming at the technical problem that when using the currently common radioactive pollution treatment method to treat Po-210 and other volatile radionuclides generated by the fourth-generation advanced fast reactor system, there is a risk of introducing radiation toxicity and chemical toxicity to the operators, the present invention provides a movable surface Po-210 pollution treatment device and a test method thereof, which can automatically identify and mark the polluted parts of the nuclear reactor system and its supporting facilities, and can remove radioactive pollution in a typical radioactive pollution system, which can not only prevent and reduce the internal irradiation risk of personnel, but also protect the radiation safety of the reactor system environment and the stable operation of the equipment.

[0065] Combined with Figure 2 , it can be understood that the mobile vehicle body 100 is responsible for loading other functional components and moving within the process site, and only needs to be able to move by itself, which can be a remotely controlled wheeled vehicle body or a tracked vehicle body. In this embodiment, the mobile vehicle body 100 includes a vehicle body frame 101, a shield plate 102, a driving wheel 103, a driven wheel 104, a power supply 105 and an inverter 106, and the overall dimensions are approximately 1619.5mm×1119mm×338mm. That is, the mobile vehicle body 100 includes: a vehicle body frame 101; a shield plate 102, which is arranged at the front end of the vehicle body frame 101; a driving wheel 103, which is arranged in the middle of the lower side of the vehicle body frame 101; a driven wheel 104, which is arranged at both ends of the lower side of the vehicle body frame 101; a power supply 105, which is installed on the vehicle body frame 101, and the power supply 105 is electrically connected to the driver of the driven wheel 104; an inverter 106, which is electrically connected to the driver of the driven wheel 104.

The overall surface is strong and durable, and it is equipped with an emergency stop switch and an audible and visual alarm, which can realize the early warning and alarm of the operating state (when encountering an emergency, it is convenient for personnel to stop urgently through the emergency stop switch to avoid the occurrence of safety accidents), and is designed with a lifting ring, which is convenient for lifting the pollution treatment test device to high-rise spaces and workplaces.

[0068] The driving wheels 103 are driven by high-load DC motors, with a single-wheel load ≥ 400 kg, and can effectively carry and move the various working modules on the upper part of the moving vehicle body 100 for processing operations. At the same time, the driving wheels 103 are symmetrically arranged in the middle, which can realize in-situ steering, facilitate processing operations in narrow spaces, can drive the moving vehicle body 100 to run on slopes with a maximum of 10°, and can be self-locked and fixed, and also has the function of not being self-locked when the power is off (when the test device needs to be transported or encounters a sudden situation resulting in power failure, the processing device can still be moved and transported through external intervention).

[0069] The driven wheels 104 are of a single-axis double-wheel structure with shock-absorbing springs, and have shock-absorbing passability themselves, and can smoothly pass through areas such as the factory floor rail doors and ramp doors.

The light rays emitted by the plurality of laser emitters 210 can form a closed positioning light area at the front end in the moving direction of the moving vehicle body 100 to ensure that the positioning assembly 200 can automatically identify and mark the pollution area. Among them, the laser emitter 210 is usually a cross laser emitter 210. As the moving vehicle body 100 travels in the work area, it assists the cleaning mechanism to automatically identify and define the surface Po-210 pollutant objects that need to be processed in a special environment, and assists the operators to carry out the fixed-point cleaning task of the surface Po-210 pollutants.

[0076] The film-forming raw material spray head 410 is a high-pressure airless spray gun, which is connected to the film-forming raw material supply system. It should be noted that the spraying raw material supply system 600 generally includes two air compressors 601, two pneumatic spraying pumps (pneumatic high-pressure airless pumps), a gas-liquid treatment system, a cleaning pump (diaphragm pump for cleaning), and a spraying pipeline, etc. The screw air compressor 601 provides compressed air power. According to different on-site decontamination and protection treatment objectives, pneumatic spraying pumps with different compression ratios are required to switch and spray different coatings. Thus, the film-forming raw material spray head 410 and the cleaning and protection are matched to form two independent systems, so as to independently set the spraying systems for the anti-fouling photomask surface epoxy resin coating and the peelable film polyurethane coating for sealing, decontamination, and protection, thereby reducing the load pressure of cleaning and switching.

[0077] Combined with Figure 9 , the spraying raw material supply system 600 includes: an air compressor 601; a first pneumatic spraying pump 602, the first pneumatic spraying pump 602 is connected to the film-forming raw material spray head 410, and under the action of the air pressure output by the air compressor 601, the first pneumatic spraying pump 602 can spray the film-forming raw material from the film-forming raw material spray head 410; a second pneumatic spraying pump 603, the second pneumatic spraying pump 603 is connected to the coated film raw material spray head 440, and under the action of the air pressure output by the air compressor 601, the second pneumatic spraying pump 603 can spray the coated film raw material from the coated film raw material spray head 440; wherein, the compression ratios of the first pneumatic spraying pump 602 and the second pneumatic spraying pump 603 are different.

[0078] Combined with Figure 10 , it should be understood that the coatings for protecting the floors, walls, ceilings, etc. of the process plant have characteristics such as high viscosity and easy curing. A pneumatic high-pressure airless pump with a ratio of 20:1 is selected for spraying; the coatings for decontaminating, sealing, or protecting the surfaces of the floors, stainless steel equipment, valves, pipelines, instruments, etc. of the existing polluted plant have characteristics such as low viscosity and can form a coated film after curing. A pneumatic high-pressure airless pump with a ratio of 10:1 is selected for spraying. According to the working conditions, there may be a process requirement for spraying multiple coatings in the same workplace, and there is an intelligent control self-circulating gas-liquid treatment system, which can control and monitor the air power, spraying air pressure power, and coating flow required during the coating spraying process, as well as the cleaning function. When coating switching is required, the gas-liquid treatment system extracts the cleaning liquid from the cleaning tank through the diaphragm pump for cleaning and automatically discharges the waste liquid into the waste liquid tank, avoiding the solidification of multiple coatings in the liquid path system due to mixing.

[0079] The dirty film clamp 430 is usually a pneumatic clamp with hooks, and the clamp is made of hard polymer material to ensure that it will not cause damage to the equipment or the floor of the process plant. One side of the hook has a right-angle intrusion angle, which can be inserted obliquely into the edge of the film stripping grid. The opposite side of the hook has spikes to ensure that the film stripping grid will not slip after clamping.

[0080] On this basis, this embodiment also includes a negative pressure dust removal component 500, which is arranged on the mobile body 100. The negative pressure dust removal component 500 is used to absorb the atomized aerosol dispersed by the film-forming raw material nozzle 410 during operation to avoid introducing excess organic matter to cause pollution to the typical environmental space.

[0081] Recombination Figure 1 and Figure 2 The negative pressure dust removal component 500 includes: a dust removal baffle frame 510, which is slidably connected to the mobile body 100. When the dust removal baffle frame 510 slides out to the front end of the moving direction of the mobile body 100, the dust removal baffle frame 510 and the mobile body 100 can enclose a closed dust removal work area, and the dust removal work area can cover the spraying range of the film-forming raw material nozzle 410; a negative pressure adsorption port 520, which is used to connect to a negative pressure source. The negative pressure adsorption port 520 is arranged at the front end of the mobile body 100, and the negative pressure adsorption port 520 is located between the mobile vehicle and the dust removal baffle frame 510 to ensure that the negative pressure dust removal component 500 can absorb the atomized aerosol dispersed by the film-forming raw material nozzle 410 during operation.

[0082] Furthermore, each side of the dust removal baffle frame 510 is provided with a ground pressure plate 511, and the ground pressure plate 511 can move vertically. The ground pressure plate 511 is used to block the gap between the storage baffle frame and the ground, further preventing the atomized aerosol from polluting the environmental space.

[0083] It can be understood that the negative pressure dust removal component 500 also includes: a first vacuum pump 531, the air inlet end of the first vacuum pump 531 is connected to the negative pressure adsorption port 520 on the dust removal baffle frame 510; a first multi-stage filter 532, the first multi-stage filter 532 is connected to the air outlet end of the first vacuum pump 531; a second vacuum pump 533, the air inlet end of the second vacuum pump 533 is connected to the negative pressure adsorption port 520 on the mobile body 100; a second multi-stage filter 534, the second multi-stage filter 534 is connected to the air outlet end of the second vacuum pump 534.

[0084] That is to say, the negative pressure dust removal assembly 500 further includes two vacuum pumps, an anti-diffusion telescopic plate, a vehicle-mounted positive dust suction port, a vehicle-mounted side dust suction port, a robotic arm dust suction port, two multi-stage filters, and a dust suction pipeline. When performing a spraying decontamination operation on the surface contaminants in the ground calibration area, the mobile vehicle body 100 automatically runs to the target area, unfolds the dust removal block, and lowers the ground pressing plate 511 (generally driven by a cylinder, and of course, other linear drivers or linear drive mechanisms can also be used to drive the ground pressing plate 511 to lift and lower), surrounding the target area to block the atomized aerosol of the sprayed paint from diffusing. When the robotic arm starts spraying, immediately open the vehicle-mounted positive dust suction port, the vehicle-mounted side dust suction port, and the robotic arm dust suction port. The vehicle-mounted dust suction port vacuum sucks the atomized aerosol diffusing in the near-space of the ground, and the robotic arm dust suction port vacuum sucks the diffusing aerosol of the dust. The aerosol sucked by the vacuum pump first enters the multi-stage filter. Using the cyclone separation principle, the large-density particles settle into the dust collection tank under the action of gravity, the medium-density particles are blocked by the isolation filter screen during the rising process, and the small-density particles are sucked by another vacuum pump into another multi-stage filter and adsorbed by the fiber filter screen. The purified gas passes through the filter element and is discharged to the atmospheric environment through the exhaust duct via the fan. When the adsorption operation runs for a specified time, the gas storage tank releases high-pressure gas to be filled into the filter for pulse backwashing and dust cleaning.

[0085] Combined with Figure 11 , to facilitate the supply of paint, this embodiment further includes a paint supply vehicle 700. The paint supply vehicle 700 is equipped with an electronic scale 701, a two-component paint tank, a stirring tank 703, a single-component paint tank, and a paint quick-loading tank 705. The paint quick-loading tank 705 is used to store the paint stirred by the stirring tank 703.

[0086] Combined again with Figure 10 , the paint supply vehicle 700 can be manually pushed to the outside of the operation site. After pre-treating the paint, the paint quick-loading tank 705 is quickly installed on the mobile vehicle body 100 to assist the decontamination operation. Specifically:

[0087] The paint supply vehicle 700 consists of a manual trolley, a control cabinet, an operation screen, an electronic scale 701, a two-component paint tank, a stirring tank 703, a single-component paint tank, a paint quick-loading tank 705, etc. When paint is needed for the operation, the paint quick-loading tank 705 is mounted on the manual trolley mounting rack, and the valves of the stirring tank 703 and the single-component paint tank are opened, and the paint in the tanks can be filled into the paint quick-loading tank 705. There is a switch valve and a quick-loading joint under the paint quick-loading tank 705, which can realize the paint switching and filling of the paint quick-loading tank 705 in this embodiment.

[0088] In this embodiment, the paint supply vehicle 700 is loaded with five kinds of ingredients and paints, such as "composite epoxy resin", "amine curing agent", "decontamination paint", "sealing paint" and "protective paint", which are numbered A, B, C, D and E respectively. According to the process requirements, the A and B paints in the two-component paint tank 702 need to be mixed and configured in a mass ratio of 1:1. The proportioning system consists of an electronic scale 701 and a control cabinet. The operating screen of the control cabinet is used to set the proportion of the paint proportion and monitor the real-time change of the mass during the proportioning process. The weighed A and B paints are added to the stirring tank 703. The tank is equipped with an electric stirrer with an adjustable stirring speed. The A and B paints can be fully stirred and homogenized to prevent the paint from stratifying. The homogenization speed can be set by program on the operating screen of the control cabinet. The C, D and E paints of the single-component paint tank can be used directly. The tank bodies for temporary storage of various types of paints are made of stainless steel. The barrel cover and barrel body are equipped with sealing rings to prevent the paint from being exposed to the air for a long time and causing oxidation and coagulation. The tank body is provided with a cleaning port and a sewage outlet for easy cleaning.

[0089] In addition, the present embodiment is also provided with a power programmable control module, which can select various operating functions of the device with one key, and compile and store the process parameter operation.

[0090] In general:

[0091] The power programmable control module is composed of a control cabinet, buttons and an operable touch screen. The control cabinet plays the role of assembling and protecting the entire control system of this embodiment and is made of stainless steel; the buttons include a main power switch, a power indicator light, a start button, an emergency stop button, a reset button, a manual / automatic program switching button, an air machine manual start / stop button, a dust suction pump manual start / stop button, a spray pump manual start / stop button, a power switching button, and a standby button, etc., which serve the operating functions of this embodiment; the operable touch screen enters the user interface to modify, edit, and store the device operation mode and process parameters, and process the alarm information, for example: control the air supply pressure during the spraying process, monitor the spraying flow rate, clean and control the pipeline after spraying, compile and store the process parameters such as the spray target type, spray distance, spray travel speed, number of spray layers, film stripping method, and film stripping speed in the "mechanical assisted decontamination and film stripping module", and control the process parameters such as the dust removal power and recoil method in the "negative pressure dust removal module", etc., to achieve the automation and programmable control of this embodiment.

[0092] In summary, the movable surface Po-210 pollution treatment device provided in this embodiment includes a mobile body 100, a positioning component 200, a multi-axis robot arm 300, a decontamination component 400 and a spraying raw material supply system 600. The positioning component 200 and the multi-axis robot arm 300 are both installed on the mobile body 100, and the decontamination component 400 is installed on the mobile end of the multi-axis robot arm 300. The positioning component 200 can automatically identify and mark the contaminated object with surface Po-210 pollution that needs to be treated. The decontamination component 400 includes a film-forming raw material nozzle 410, a film-removing scraper 420, a dirty film clamp 430 and a coating film raw material nozzle 440. The spraying raw material supply system 600 is installed on the mobile body 100 and can provide corresponding raw materials to the film-forming raw material nozzle 410 and the coating film raw material nozzle 440 respectively. The film-removing scraper 420 can shovel up the dirty film under the drive of the multi-axis robot arm 300, and the dirty film clamp 430 can clamp the dirty film.

[0093] When in use, the remote-controlled mobile body 100 moves within the Po-210 cleaning operation range. When the mobile body 100 moves to the corresponding polluted object removal station, the polluted object is identified and marked by the positioning component 200 to mark the spraying area and serve as a warning. The multi-axis robotic arm 300 moves the film-forming raw material nozzle 410 and the coating film raw material nozzle 440 to the spraying station.

[0094] The film-forming raw material nozzle 410 is used to spray the film-forming raw material onto the surface of the contaminated object so that the film-forming raw material covers the contaminated area. After the film-forming raw material is solidified to form a dirty film, the film-peeling scraper 420 is moved to the film-peeling point by the multi-axis robot 300 to scoop up the dirty film, and then the dirty film scooped up by the film-peeling scraper 420 is clamped by the dirty film clamp 430. Finally, the multi-axis robot 300 drives the dirty film clamp 430 to move to peel off the dirty film from the contaminated object to automatically complete the film peeling and decontamination operation.

[0095] Alternatively, the film forming raw material nozzle 410 is sprayed onto the surface of the polluted object through the coating film raw material nozzle 440 to decontaminate, seal or protect the surface of the metal equipment serving in the process plant.

[0096] In summary, the movable surface Po-210 contamination treatment device provided in this embodiment can remove radioactive contamination under a typical radioactive contamination system, which can not only prevent and reduce the internal exposure risk of personnel, but also protect the radiation safety of the reactor system environment and the stable operation of the equipment.

[0097] Example 2

[0098] This embodiment provides a method for testing a movable surface Po-210 contamination treatment device, which is used to test the movable surface Po-210 contamination treatment device described in Example 1, and includes the following steps:

[0099] Inverter power supply capacity test: by detecting the voltage at the output end of the inverter 106, a discharge test of the inverter power supply is performed using a resistor with a fixed resistance value, and the inverter power supply capacity is calculated based on the discharge time.

[0100] Driving performance test of mobile body 100: the mobile body 100 is driven to a test section, which includes a ramp greater than or equal to 10°, a deep ditch with a width ≥50mm and a depth ≥50mm, and a shallow ditch with a width ≥100mm and a depth ≤10mm. The mobile body 100 is tested for moving forward, backward, turning on the spot, climbing and descending reciprocating driving in each test section. The device shall not get stuck or slip during the test.

[0101] Feed test of the raw material supply system: Use colored solvents to fill them into each paint tank of the paint supply vehicle 700, and fill the cleaning tank with clean water, switch the spray pipeline for paint spraying, and clean the pipeline to test the spray raw material supply system 600.

[0102] Combination Figure 10 Specifically, use a colored solvent with a viscosity similar to that of the actual paint and fill it into the corresponding tube body A / B respectively, fill the cleaning tank C with clean water, and replace the spray pipeline with a transparent hose to facilitate observation by personnel. During the test, first use the first pneumatic spray pump 602 to spray the paint. After the first pneumatic spray pump 602 completes the spraying, the clean water in tank C is introduced into the spray pipeline through the switching system, and the waste liquid is discharged into the waste liquid tank to complete the pipeline cleaning. After the cleaning is completed, the solvent in tank B is introduced into the spray pipeline through the switching system to complete the paint switching process. During the test, the flow phenomenon of liquids of different colors in the pipeline should be able to be intuitively observed to determine the operability and stability of the switching system.

[0103] Among them, in this embodiment, an AC-driven air compressor 601 is used as a power source to drive the air compressor 601, and the compressed air is correspondingly distributed to the spray pump (30:1), the spray pump (20:1) and the diaphragm pump through the air source processing system. The spray pump (30:1) extracts the light finish paint in the paint tank and sprays it through an airless spray gun. After the spraying of the light finish paint is completed, the paint switching system will stop the spraying operation of the airless pump A, control the air source processor to drive the diaphragm pump to extract the cleaning liquid in the cleaning tank, and introduce the cleaning liquid into the spraying circuit. The cleaning liquid is introduced into the waste liquid tank of the device through the quick exhaust valve. The whole process can be completed in the system pipeline, without the spraying treatment of waste paint, which can effectively meet the zero generation of pollutants in the process plant. The test data is shown in Table 1.

[0104] Table 1

[0105]

[0106] Therefore, through the parameter measurement of the screw air compressor and the pneumatic high-pressure airless sprayer, it was confirmed that the use of the screw air compressor under the working conditions of 0.8MPa, 250L / min can efficiently and stably drive the pneumatic high-pressure airless sprayer with a compression ratio of 46:1 of the Po-210 pollution protection and treatment device to carry out the spraying process; through the parameter measurement of the screw air compressor and the pneumatic diaphragm pump, it was confirmed that the use of the screw air compressor under the working conditions of 0.8MPa, 250L / min can stably drive the pneumatic diaphragm pump with a compression ratio of 1:1 of the Po-210 pollution protection and treatment device to carry out the cleaning process of the spray pipeline.

[0107] Paint spraying test: A set experimental area is demarcated on the horizontal ground, and a paint spraying test is performed on the ground through the film forming raw material nozzle 410 or the coating film raw material nozzle 440.

[0108] Specifically, a 1000mm×1000mm area is demarcated on the horizontal ground, the decontamination mode is set to "plane", the system is started, and the multi-axis robot 300 drives the corresponding nozzle to spray paint on the horizontal ground; then a 1000mm×1000mm area is demarcated on the vertical wall, the decontamination mode is set to "wall", the system is started, and the multi-axis robot 300 drives the corresponding nozzle to spray paint on the vertical wall; select a three-dimensional object with a volume size of ≤400mm×400mm×500mm, set the decontamination mode to "three-dimensional", start the system, and the multi-axis robot 300 drives the corresponding nozzle to spray paint on each side of the three-dimensional object. In this example, the entire spraying process is smooth and smooth, the spraying pressure value is adjustable, the spraying height distance is adjustable, the spraying action speed is adjustable, and the spraying flow rate can be monitored.

[0109] Dirt film stripping test: After the paint spraying operation is completed, the film stripping scraper 420 is moved to the film stripping point by the multi-axis robot arm 300 to scrape up the dirty film, and the dirty film scraped up by the film stripping scraper 420 is clamped by the dirty film clamp 430, and the dirty film clamp 430 is driven to move by the multi-axis robot arm 300 to perform the dirty film stripping test.

[0110] Specifically, an area of ​​1000mm×1000mm is demarcated on the horizontal ground. After the paint spraying operation is completed, the multi-axis robot arm 300 drives the pneumatic clamp to hook a corner of the film stripping net with the clamp under manual assistance, and starts the switch to clamp the film stripping net with the clamp. According to the set program, the film stripping net and the solidified coating film are peeled off from the sprayed target. In this example, the film stripping process is smooth and the film stripping speed and height are adjustable.

[0111] Smoke removal test of negative pressure dust removal assembly 500: a smoke generating device is placed in the experimental area, and the negative pressure dust removal assembly 500 is turned on to perform a smoke removal test of the negative pressure dust removal assembly 500.

[0112] Specifically, within the negative pressure dust removal area with a defined size of 1000mm × 1000mm, a smoke-generating device is manually placed, and the negative pressure system is turned on. There should be no visible smoke and dust overflowing outside the dust removal hood.

[0113] Negative pressure dust removal assembly 500 aerosol dispersion prevention test: Conduct on-site spraying in the experimental area, and turn on the negative pressure dust removal assembly 500 to conduct the negative pressure dust removal assembly 500 aerosol dispersion prevention test.

[0114] Specifically, conduct on-site spraying within the ground spraying area with a defined size of 1000mm × 1000mm. During the construction process under simulated working conditions, it should be observed that there is no splashing and dispersed aerosol flying outside the negative pressure dust removal hood.

[0115] Among them, in this embodiment, the dust removal hood of the negative pressure dust removal module is designed integrally with the vehicle-mounted module and is in a retractable state. Under normal conditions, the dust removal hood is retracted into the vehicle body and does not occupy too much space. When spraying-dust removal work needs to be carried out, the system will control the dust removal hood to extend from both sides and the front of the vehicle body. The sliding plate under the dust removal hood descends under the action of the cylinder to fit the ground, and the baffle above is driven by the cylinder to form a semi-closed cover with an opening. The size of the opening can allow the robotic arm to enter and carry out spraying operations. There is a small air curtain nozzle installed at the opening above the dust removal hood, which can introduce air flow from the outside to the inside. The side plate under the dust removal hood is installed with a negative pressure dust removal adsorption port, which can adsorb paint particles and aerosols into the filter barrel. The dust removal device introduces an active air flow unidirectional working mode to adaptively enclose the spraying work area, so that the internal aerosol cannot disperse outward, reducing the pollution degree of the entire working environment and ensuring personnel safety. The performance test data of the negative pressure dust removal assembly is shown in Table 2.

[0116] Table 2

[0117]

[0118] By measuring the negative pressure parameters of the ring vacuum pump, it can be confirmed that using a 0.85kw ring vacuum pump to discharge / absorb dispersed aerosols can meet the dust removal process requirements of the Po-210 pollution protection and treatment device.

[0119] In addition, it also includes the paint supply vehicle test: Conduct mass ratio according to the required proportion of paint. The paint in paint tanks A / B is pumped into the mixing tank through a feeding pump, and the paint is stirred and homogenized in the mixing tank, and the stirring speed is adjustable. During the paint extraction process, the electronic scales equipped on tanks A / B monitor the extracted paint quality.

[0120] In summary, for the test method of the movable surface Po-210 pollution treatment device provided in this embodiment, the capacitance test of the inverter power supply, the driving performance test of the mobile vehicle body, the feeding test of the raw material supply system, the coating spraying test, the contaminated film stripping test, the smoke removal test of the negative pressure dust removal component, the anti-aerosol dispersion test of the negative pressure dust removal component, and the coating supply vehicle test are respectively carried out, which meet the requirements of the six properties of the device, namely reliability, maintainability, supportability, testability, safety, and environmental adaptability, as specified in GJB9001C-2017 "Quality Management System Requirements", so as to ensure that the movable surface Po-210 pollution treatment device can not only prevent and reduce the internal irradiation risk of personnel, but also protect the radiation safety of the reactor system environment and the stable operation of the equipment.

[0121] It should be understood that the above description is only a specific embodiment of the present invention and is not used to limit the protection scope of the present invention.
