Description

Technical Field

[0001] This invention relates to the field of dust treatment technology, and in particular to a dust treatment system applied to laser decontamination. Background Technology

[0002] During the use of nuclear equipment, a large amount of radioactive contaminants are generated on the surface. In order to prevent the radioactive substances on the surface of nuclear equipment from affecting the health of workers, it is necessary to remove the radioactive substances from the surface of nuclear equipment. At present, high-energy laser decontamination technology, as a new generation of surface decontamination treatment technology, has broad application prospects in the fields of deep decontamination of metal surfaces and decontamination of radioactive hot spots due to its characteristics such as low secondary waste generation, ability to work in confined spaces, and ease of automation. It is widely used in the field of nuclear power equipment decontamination.

[0003] High-energy laser robots generate a large amount of radioactive dust and fumes during decontamination. Currently, existing technologies typically involve setting up adsorption tubes, using the negative pressure generated inside the tubes to draw in the dust and fumes mixture, and then using a collection device to filter and collect it. However, the problem with existing technologies is that adsorption tubes alone cannot effectively adsorb large amounts of radioactive dust and fumes. The radioactive dust and fumes are not separated, and the dust is easily discharged into the outside with the fumes, causing air pollution. At the same time, the nuclear radiation generated by the radioactive dust can also threaten the health of workers. Summary of the Invention

[0004] The purpose of this invention is to provide a dust treatment system for laser decontamination that addresses the shortcomings of existing technologies. Through the coordinated design of a dust adsorption device, a cyclone separator, an air supply device, and a filtration device, this invention effectively solves the problems in existing technologies, such as the inability of adsorption devices to effectively adsorb radioactive dust, the failure to separate radioactive dust and flue gas in advance, and poor filtration effects.

The top, front and bottom of the suction housing are respectively provided with an upper air inlet channel, a side air inlet channel and an exhaust pipe. The upper air inlet channel and the side air inlet channel are tangential to the air supply channel. The exhaust pipe passes through the partition and extends into the processing chamber and is connected to the central air inlet.

[0010] Furthermore, the air supply channel is cylindrical, and a rotating shaft is provided horizontally inside the air supply channel. The two ends of the rotating shaft are rotatably connected to the suction housing, and the two ends of the rotating shaft are provided with spiral brushes with opposite rotation directions.

[0011] Furthermore, the number of the smoke and dust adsorption devices is three, and the suction housings are all located at the bottom of the adsorption chamber, and are respectively located on the left side, right side and opposite side of the cabinet door, and are closely attached to the side wall of the cabinet.

[0012] Furthermore, the cyclone separator includes an air inlet housing, the upper part of which is cylindrical and the lower part is funnel-shaped. The top, upper outer wall and bottom of the air inlet housing are respectively provided with an air outlet channel, at least one feed inlet and a discharge outlet. Inside the air inlet housing, there are spiral guide plates that decrease in size from top to bottom around the air outlet channel. The air inlet housing is detachably connected to the collecting component, and the discharge outlet extends into the collecting component. The feed inlet is detachably connected to the dual-head amplifier.

[0013] Furthermore, the collecting component includes an outer cylinder made of radiation shielding material and an inner cylinder made of corrosion-resistant metal material. The tops of the outer cylinder and the inner cylinder are designed with an open structure. The bottom of the outer cylinder is provided with at least one protrusion, and the top of the protrusion is provided with an insulating and water-repellent layer. The inner cylinder can be inserted into the inner protrusion from the top opening of the outer cylinder. The outer cylinder is detachably connected to the air inlet housing. The discharge port extends into the interior of the inner cylinder and fits tightly against its top opening.

[0014] Furthermore, the guide plate is provided with a flow guide plate located at the feed inlet.

[0016] Furthermore, the air supply device includes an air compressor, the air compressor has an air supply pipe at its air outlet, and the air supply pipe has several branch pipes, which are respectively connected to the first side air inlet and the second side air inlet.

[0017] Furthermore, a pressure sensor is provided in the adsorption chamber, and a controller is provided in the processing chamber. The pressure sensor, the controller, and the air compressor are electrically connected.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention effectively solves the problems in existing technologies, such as the inability of adsorption devices to effectively adsorb radioactive dust, the failure to separate radioactive dust and flue gas in advance, and poor filtration effect, through the coordinated design of a dust adsorption device, a cyclone separator, an air supply device, and a filtration device.

[0020] 1. By setting up multiple dust adsorption devices, radioactive dust in different directions can be effectively adsorbed, increasing the adsorption range and effect. The design of the combination of dual amplifier and air compressor creates a negative pressure state inside the cabinet, which effectively enhances the output air volume, increases the adsorption force, improves the adsorption efficiency of dust and flue gas, and prevents dust and flue gas from leaking out.

[0021] 2. By using a cyclone separator, radioactive dust falls into the collection unit at the bottom under the action of the guide plate. The separated flue gas enters the filtration device through the exhaust channel, thereby improving the separation effect of radioactive dust and flue gas, extending the service life of the filter material, reducing the frequency of filter material replacement, reducing the amount of radioactive solid waste generated, and avoiding air pollution and threats to the health and safety of workers.

[0022] 3. The filtration device is equipped with a filter element layer and an activated carbon layer. The filter element layer can effectively filter and remove fine particulate matter remaining in the flue gas, while the activated carbon layer adsorbs radioactive substances and aerosols in the flue gas, effectively intercepting pollutants, enhancing the filtration effect, and preventing the flue gas from being directly discharged into the outside air, thus avoiding serious pollution to the surrounding environment.

[0023] 4. The collection component consists of an outer cylinder and an inner cylinder. The inner cylinder is placed on a protrusion at the bottom of the outer cylinder. The protrusion supports the inner cylinder and prevents internal moisture from condensing and soaking it. The outer cylinder is made of radiation shielding material, which can shield the nuclear radiation generated by the radioactive dust collected in the inner cylinder and prevent workers from being excessively exposed to the radioactive dust in the inner cylinder.

[0024] 5. A pressure sensor is installed inside the adsorption chamber to monitor the pressure of radioactive dust and flue gas in real time. When the pressure is high, the controller increases the air output of the air compressor to increase the negative pressure inside the cabinet, thereby enhancing the output of radioactive dust and flue gas and improving the adsorption capacity. Conversely, when the pressure is low, the controller reduces the air output of the air compressor to reduce the output of radioactive dust and flue gas, thus saving energy.

[0034] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0035] See Figures 1 to 8 This invention provides a dust treatment system for laser decontamination, including a cabinet 30 with a cabinet door 31. The cabinet door 31 is divided into a left cabinet door and a right cabinet door. In use, the left and right cabinet doors are pushed open to the sides to facilitate the placement of workpieces. The interior of the cabinet is divided into an adsorption chamber and a processing chamber by a partition 32. The adsorption chamber is located above the partition 32, and the processing chamber is located below the partition 32. The adsorption chamber is equipped with at least one dust adsorption device, and the processing chamber is equipped with a cyclone separator, an air supply device, and a filter device.

[0036] The dust adsorption device includes a suction housing 1. Since radioactive dust has a certain weight, the suction housing 1 is positioned at the bottom of the adsorption chamber to achieve a better adsorption effect. To prevent radioactive dust accumulation between the suction housing 1 and the cabinet 30, the side of the suction housing 1 is flush against the side wall of the cabinet 30. An air delivery channel 2 is provided inside the suction housing 1, running along its length. An upper air inlet channel 3, a side air inlet channel 4, and an exhaust pipe 5 are respectively located on the top, front, and bottom of the suction housing 1. The upper air inlet channel 3, side air inlet channel 4, and exhaust pipe 5 are all connected to the air delivery channel 2 and are tangentially positioned to it. This tangential air intake reduces the turning angle of the airflow entering the air delivery channel 2, decreasing the resistance to airflow and increasing the airflow velocity. To ensure effective air intake, the upper air intake channel 3 and the side air intake channel 4 are used to adsorb dust from different directions. The exhaust pipe 5 passes through the partition 32 and extends into the treatment chamber, connecting to the cyclone separator. Preferably, there are three dust adsorption devices. The three suction housings 1 are respectively set at the bottom of the adsorption chamber, located on the left, right and opposite sides of the cabinet 30 and close to the side wall of the cabinet 30. At this time, the radioactive dust floating at a high position in the adsorption chamber enters the suction housing 1 through the three upper air intake channels 3 in different directions along the airflow. The heavier radioactive dust at a low position in the adsorption chamber enters the suction housing 1 through the three side air intake channels 4 in different directions along the airflow. This can effectively adsorb radioactive dust in different directions in the adsorption chamber, effectively improve the adsorption range and adsorption effect, and prevent radioactive dust leakage.

[0037] The cyclone separator includes a cyclone separator 6, a collection component 7, and a dual-head amplifier 8. The cyclone separator 6 includes an inlet housing 9, which is cylindrical at the top and funnel-shaped at the bottom. The upper outer wall of the inlet housing 9 is lined with a lead shielding layer to shield radioactive dust entering the cyclone separator 6. The top of the inlet housing 9 is provided with an exhaust channel 10 to facilitate the discharge of flue gas into a filtration device. The upper outer wall of the inlet housing 9 is provided with at least one feed inlet 11, preferably three feed inlets 11. The air inlet housing 9 is provided with spiral guide plates 13 arranged at equal intervals along its outer wall, or staggered vertically at equal intervals. These guide plates 13, arranged in a descending spiral pattern around the outlet channel 10, cause the radioactive dust entering the cyclone separator 6 to rotate at high speed, promoting the particles and dust to fall into the collection component 7 at the bottom for easy collection. The guide plates 13 are equipped with guide plates 24 located at the feed inlet 11. Preferably, there are three guide plates 24, corresponding to the number of feed inlets 11. The guide plates 24 guide the incoming air... Radioactive dust moves downwards along the guide plate 13. The bottom of the air inlet housing 9 has an outlet 12. The air inlet housing 9 is detachably connected to the collection component 7. This detachable connection facilitates timely handling of radioactive dust within the collection component 7, and the outlet 12 extends into the collection component 7. The dual-head amplifier 8 is detachably connected to the inlet 11, and can be connected using threaded, flanged, insert, locking, or press-locking methods. The dual-head amplifier 8 is designed as a pipe, with each inlet 11 connected to one dual-head amplifier 8. There are 3 units of 8. The dual-head amplifier 8 is equipped with a first side air inlet 14 and a central air inlet 15. The first side air inlet 14 is connected to the air supply device. The input air force accelerates the radioactive dust to rotate at high speed in the cyclone separator 6, thereby improving the separation efficiency. The central air inlet 15 is connected to the exhaust pipe 5, which facilitates the collection and treatment of radioactive dust and flue gas adsorbed in the dust adsorption device. By utilizing the amplification effect of the dual-head amplifier 8, its output air volume is amplified, increasing the negative pressure in the suction housing 1, thereby improving the dust removal efficiency and dust removal effect.

[0038] The filtration device includes a filter cartridge 25 and an adsorption cartridge 26. Both the filter cartridge 25 and the adsorption cartridge 26 are made of lead, which serves as a shielding material to effectively prevent radioactive materials from directly penetrating the cartridge and being released into the outside air, polluting the environment and threatening the safety of workers. The filter cartridge 25 contains a filter element, and the adsorption cartridge 26 is filled with activated carbon. The air inlet of the filter cartridge 25 is connected to the air outlet channel 10, and the air outlet of the filter cartridge 25 is connected to the air inlet of the adsorption cartridge 26. The flue gas after cyclone separation passes through the air outlet channel 10. Entering the filtration device, the filter element in the filter cartridge 25 can effectively filter and remove the fine particulate matter remaining in the flue gas. The activated carbon in the adsorption cartridge 26 can adsorb radioactive substances and aerosols in the flue gas, effectively intercepting pollutants and enhancing the filtration effect. The air amplifier 16 is installed on the air outlet of the adsorption cartridge 26. The air amplifier 16 is provided with a second side air inlet 17 and an air outlet 18. The second side air inlet 17 is connected to the air supply device. The air amplifier 16 effectively increases the airflow velocity and improves the air output efficiency.

[0039] Specifically, the air supply channel 2 is cylindrical, and a rotating shaft 19 is horizontally arranged inside the air supply channel 2. The two ends of the rotating shaft 19 are rotatably connected to the suction housing 1. A bearing is provided at the connection between the rotating shaft 19 and the suction housing 1. The rotating shaft 19 is connected to the suction housing 1 through the bearing. The two ends of the rotating shaft 19 are provided with spiral brushes 20 with opposite rotation directions. The spiral brushes 20 are adapted to the upper air inlet channel 3 and the side air inlet channel 4. During their rotation, the dust and airflow on both sides of the air supply channel 2 are transported to the exhaust pipe 5, which facilitates the discharge of radioactive dust and smoke.

[0040] Specifically, the collecting component 7 includes an outer cylinder 21 made of radiation shielding material and an inner cylinder 22 made of corrosion-resistant metal. The radiation shielding material is preferably lead or its alloy, and the corrosion-resistant metal is stainless steel. The tops of the outer cylinder 21 and the inner cylinder 22 are designed with an open structure. The bottom of the outer cylinder 21 is provided with at least one protrusion 23, preferably one protrusion 23. The top of the protrusion 23 is provided with an insulating and hydrophobic layer. The insulating and hydrophobic layer can block the electron flow between the outer cylinder 21 and the metal inner cylinder 22, preventing the formation of galvanic corrosion. The inner cylinder 22 can be inserted into the inner protrusion 23 through the top opening of the outer cylinder 21. The protrusion 23 supports the inserted inner cylinder 22, preventing the inner cylinder 22 from being soaked after the internal moisture condenses and accumulates. The outer cylinder 21 is detachably connected to the air inlet shell 9, making it easy to take out the inner cylinder 22 inside the outer cylinder 21 and to facilitate timely treatment of the radioactive dust collected inside the inner cylinder 22. The discharge port 12 extends into the inner cylinder 22 and fits tightly with its top opening to prevent the leakage of radioactive dust.

[0041] Specifically, the air supply device includes an air compressor 27. The air compressor 27 has an air supply pipe 28 at its outlet end. The air supply pipe 28 has several branch pipes 29. There are four branch pipes 29, which are connected to three first lateral air inlets 14 and one second lateral air inlet 17, respectively. The air compressor 27 outputs airflow. The airflow passes through the air supply pipe 28 and the branch pipes 29 and enters the interior of the dual-head amplifier 8 from the first lateral air inlet 14 and the second lateral air inlet 17 of the air amplifier 16, so that a high-speed, high-capacity airflow is formed inside the dual-head amplifier 8 and the air amplifier 16, forming a negative pressure to accelerate the discharge of flue gas.

[0042] Specifically, a pressure sensor is installed inside the adsorption chamber, and a controller is installed inside the processing chamber. The pressure sensor, controller, and air compressor 27 are electrically connected. The pressure sensor can monitor the pressure of radioactive dust and flue gas inside the adsorption chamber in real time. When the pressure is high, the controller increases the airflow of air compressor 27 to enhance the negative pressure inside the adsorption chamber, increase the output volume of radioactive dust and flue gas, and enhance the adsorption capacity. Conversely, when the pressure is low, the controller reduces the airflow of air compressor 27 to reduce the output volume of radioactive dust and flue gas, thereby achieving the purpose of saving energy.

[0043] The working principle of this invention is as follows:

[0044] During operation, the air compressor 27 is started, and the air compressor 27 outputs airflow from its outlet. The airflow enters the dual-head amplifier 8 from the first side towards the air inlet 14, creating a high-speed, high-capacity airflow within the dual-head amplifier 8. The dual-head amplifier 8 draws air from the suction housing 1 through the exhaust pipe 5, creating a negative pressure within the suction housing 1. This causes the radioactive dust and flue gas in the adsorption chamber to enter the suction housing 1 through the upper air inlet channel 3 and the side air inlet channel 4, and then enter the cyclone separator 6 through the exhaust pipe 5. The guide plate 13 and the diversion plate 24 cause the radioactive dust entering the cyclone separator 6 to rotate downwards at high speed. The particles and dust fall into the inner cylinder 22 at the bottom through the discharge port 12. The flue gas enters the filter device through the exhaust channel 10. The filter element in the filter cylinder 25 effectively filters and removes the fine particulate matter remaining in the flue gas. The activated carbon in the adsorption cylinder 26 can... The adsorbed flue gas contains radioactive and aerosol substances. The filtered flue gas is discharged from the outlet of the adsorption cylinder 26. An air amplifier 16 is installed at the outlet of the adsorption cylinder 26. The airflow output by the air compressor 27 enters the air amplifier 16 from the second side through the air inlet 17, forming a high-speed, high-capacity airflow inside the air amplifier 16. This accelerates the discharge of the filtered flue gas and improves the efficiency of flue gas treatment. At the same time, a pressure sensor monitors the pressure of radioactive dust and flue gas in the adsorption chamber in real time. When the pressure is high, the controller increases the airflow of the air compressor 27 to enhance the negative pressure in the adsorption chamber, increase the output volume of radioactive dust and flue gas, and enhance the adsorption capacity. Conversely, when the pressure is low, the controller reduces the airflow of the air compressor 27 to reduce the output volume of radioactive dust and flue gas, thereby saving energy.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
