Description

Technical Field

[0001] The present application relates to the technical field of radioactive waste gas treatment, and in particular to a radioactive waste gas purification device. Background Art

[0002] With the rapid development of nuclear medicine, radioactive drugs are also widely used in clinical practice. Due to the particularity of radioactive drugs, radioactivity and radioactive waste will be generated. In particular, the radioactive drug 131I used to treat hyperthyroidism, thyroid cancer and other diseases is not only radioactive but also volatile, which produces aerosols in the air and adsorbs on objects, which is easy to cause radioactive pollution and radioactive hazards to personnel and the environment. In order to avoid radioactive hazards in non-confined places, reduce the spread of pollution in non-confined radioactive operation sites, make the on-site environment meet the relevant national standards, and make the treated waste gas meet the relevant national emission standards, it is necessary to filter the discharged waste gas to avoid the ecological environment from being polluted by the use of nuclear medicine.

[0003] In the related art, it is difficult for the radioactive waste gas filtering device to continue filtering the waste gas when a failure occurs, and when the filter element in the filtering device is replaced, there is no way to filter the waste gas, that is, the waste gas cannot be filtered continuously. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the related art. To this end, the present application proposes a radioactive waste gas purification device, which realizes that by setting at least two filter chambers, they can be used alternately. When one of the filter chambers fails or the filter element needs to be replaced, the other filter chamber can be used to filter the waste gas, ensuring that the waste gas can be continuously filtered to avoid pollution to the environment.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0049] Combine the following Figures 1 to 6 The radioactive waste gas purification device of the present application is described.

[0050] According to the embodiments of the present application, Figure 1 As shown, the radioactive waste gas purification device includes an air source inlet 1, a first filter box chamber 2, a fan assembly 3, an exhaust pipe 4 and at least one second filter box chamber 5; one end of the first filter box chamber 2 is connected to the air source inlet 1, and the other end of the first filter box chamber 2 is connected to the fan assembly 3; one end of the second filter box chamber 5 is connected to the air source inlet 1, and the other end of the second filter box chamber 5 is connected to the fan assembly 3 through a four-way 255, and replaceable filter elements 6 can be placed in the first filter box chamber 2 and the second filter box chamber 5; the exhaust pipe 4 is connected to the fan assembly 3; the fan assembly 3 is used to transport the gas of at least one of the first filter box chamber 2 and the second filter box chamber 5 to the exhaust pipe 4.

[0051] When in use, the exhaust gas is transported to the first filter box chamber 2 and the second filter box chamber 5 through the gas source inlet 1, and the fan assembly 3 transports the gas in the first filter box chamber 2 to the discharge pipe 4, and discharges it to the outside through the discharge pipe 4. When the exhaust gas passes through the first filter box chamber 2, the filter element 6 in the first filter box chamber 2 filters the exhaust gas, so that the gas transported to the outside through the discharge pipe 4 meets the requirements. At this time, the fan assembly 3 only transports the gas in the first filter box chamber 2 to the discharge pipe 4, and the gas in the second filter box chamber 5 remains unchanged, that is, the exhaust gas at the gas source inlet 1 can only be discharged to the outside through the first filter box chamber 2. When the filter element 6 in the first filter box chamber 2 needs to be replaced or the first filter box chamber 2 fails, the fan assembly 3 stops transporting the gas in the first filter box chamber 2 to the discharge pipe 4, and instead transports the gas in the second filter box chamber 5 to the discharge pipe 4, and filters the exhaust gas through the filter element 6 in the second filter box chamber 5. Furthermore, by setting up at least two filter chambers, they can be used alternately. When one of the filter chambers fails or the filter element 6 needs to be replaced, the other filter chamber can be used to filter the exhaust gas, ensuring that the exhaust gas can be continuously filtered to avoid pollution to the environment.

[0052] It should be noted that the fan assembly 3 can also simultaneously transport the gas in the first filter box chamber 2 and the second filter box chamber 5 to the exhaust pipe 4, so that the first filter box chamber 2 and the second filter box chamber 5 can filter the exhaust gas at the same time, thereby improving the exhaust gas processing capacity and efficiency.

[0053] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the first filter box chamber 2 is provided with an air outlet, and the air outlet is connected to the fan assembly 3 through the telescopic gas channel 21. A pressing assembly 22 is provided at the connection between the air outlet and the telescopic gas channel 21, and the pressing assembly 22 is used to make the connection between the air outlet and the telescopic gas channel 21 tighter. When in use, one end of the telescopic gas channel 21 is connected to the fan assembly 3, and the other end of the telescopic gas channel 21 is connected to the air outlet of the first filter box chamber 2, and at the same time, the connection between the other end of the telescopic gas channel 21 and the air outlet is made tighter through the pressing assembly 22, thereby improving the sealing performance of the connection between the telescopic gas channel 21 and the air outlet, and reducing the space between the telescopic gas channel 21 and the air outlet, thereby effectively reducing the residual exhaust gas in the first filter box chamber 2, and effectively guiding the wind direction, reducing the energy consumption caused by unnecessary wind resistance.

[0054] In the embodiments of the present application, Figure 1 and Figure 2As shown, the telescopic gas channel 21 includes a connecting pipe 211 and a sealing canvas 212, one end of the connecting pipe 211 is connected to the fan assembly 3, the other end of the connecting pipe 211 is connected to one end of the sealing canvas 212, and the other end of the sealing canvas 212 is connected to the air outlet of the first filter box chamber 2. The canvas has a certain flexibility, so that the other end of the sealing canvas 212 can move closer to or away from one end, thereby making the connecting pipe 211 have a telescopic property. However, it should be understood that the telescopic gas channel 21 can also be composed of any other suitable components with telescopic properties.

[0055] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the clamping assembly 22 includes a first driving member 221 and at least one rotating member 222. The first driving member 221 is installed on the side wall of the first filter box chamber 2. The first driving member 221 is connected to the rotating member 222. The first driving member 221 is used to drive the rotating member 222 to rotate. The rotating member 222 and the telescopic gas channel 21 are connected through a locking link 223. One end of the locking link 223 is connected to the rotating member 222, and the other end of the locking link 223 is connected to the end of the telescopic gas channel 21 close to the gas outlet. When in use, the first driving member 221 drives the rotating member 222 to rotate, so that the rotating member 222 drives the locking link 223 to move. When the locking link 223 moves, it drives the telescopic gas channel 21 close to or away from the gas outlet, so that when the exhaust gas is filtered through the first filter box chamber 2, the telescopic gas channel 21 can be opened to the gas outlet, reducing the residual exhaust gas between the telescopic gas channel 21 and the gas outlet.

[0056] In the embodiment of the present application, the first driving member 221 is, for example, a motor, and the motor drives the rotating member 222 to rotate, thereby automatically compressing the connection between the telescopic gas channel 21 and the gas outlet. However, it should be understood that the first driving member 221 can also be any other suitable driving element, such as a hand wheel, to manually compress the connection between the telescopic gas channel 21 and the gas outlet.

[0057] In the embodiment of the present application, the rotating member 222 is, for example, a gear, but it should be understood that the rotating member 222 may also be any other suitable rotatable element.

[0058] In one embodiment of the present application, Figure 1 and Figure 2As shown, the clamping assembly 22 includes two or more rotating members 222, the first driving member 221 is connected to one of the rotating members 222, and the clamping assembly 22 includes a synchronous belt 224, and each rotating member 222 is connected to the synchronous belt 224. When in use, different rotating members 222 are installed at different positions, and a locking link 223 is provided between the rotating member 222 and the telescopic gas channel 21, so that different rotating members 222 can press different positions of the telescopic gas channel 21. The first driving member 221 drives one of the rotating members 222 to rotate, and when one of the rotating members 222 rotates, it drives the synchronous belt 224 to rotate with it. The synchronous belt 224 can drive all the rotating members 222 to rotate with it, so that the rotating members 222 of all the rotating members 222 are kept synchronous, and different positions of the telescopic gas channel 21 can be pressed synchronously.

[0059] In one embodiment of the present application, Figure 1 and Figure 3 As shown, the first filter box chamber 2 is provided with an air inlet, which is connected to the gas source inlet 1 through the second gas channel 23, and the telescopic gas channel 21 and the second gas channel 23 are both provided with an air volume detection member 24. When in use, under the action of the fan assembly 3, the exhaust gas at the gas source inlet 1 enters the second gas channel 23, and then the exhaust gas enters the first filter box chamber 2 through the air inlet. After the first filter box chamber 2 filters the exhaust gas, the gas in the first filter box chamber 2 is transported to the telescopic gas channel 21 through the air outlet. The air volume detection element 24 on the telescopic gas channel 21 and the second gas channel 23 detects the air volume of the gas passing through the telescopic gas channel 21 and the second gas channel 23 in real time, and transmits the detection data to the corresponding processor for processing and analysis, by comparing the air volume in the telescopic gas channel 21 and the air volume in the second gas channel 23. When the air volume in the telescopic gas channel 21 is greater than the air volume in the second gas channel 23, it means that the filter element 6 in the second filter box chamber 5 is still working normally. When the air volume in the telescopic gas channel 21 is the same as the air volume in the second gas channel 23, it means that the filter element 6 in the second filter box chamber 5 is full or blocked, so that the staff can quickly grasp the actual working conditions of the second filter box chamber 5.

[0060] In one embodiment of the present application, Figure 1 and Figure 3As shown, a first valve 25 is provided on the second gas channel 23, and the first valve 25 is used to control whether the first filter box chamber 2 is connected with the gas source inlet 1. When in use, the first valve 25 is opened, so that the first filter box chamber 2 is connected with the gas source inlet 1, and the first valve 25 is closed, then the first filter box chamber 2 and the gas source inlet 1 are not connected. When the first filter box chamber 2 is used to filter the exhaust gas, the first valve 25 is opened, and the exhaust gas at the gas source inlet 1 can flow into the first filter box chamber 2 through the first valve 25. When the filter element 6 in the first filter box chamber 2 is full and needs to be replaced or the first filter box chamber 2 fails, the first valve 25 is closed, so that the exhaust gas at the gas source inlet 1 cannot flow into the first filter box chamber 2, so that when the staff replaces or repairs the filter element 6 in the first filter box chamber 2, they will not be affected by the exhaust gas, thereby ensuring the health of the staff.

[0061] In the embodiment of the present application, the structure of the second filter chamber 5 is the same as that of the first filter chamber 2, and a repeated description thereof will not be given here.

[0062] In one embodiment of the present application, Figure 1 and Figure 3 As shown, the fan assembly 3 includes at least two fans 31, one of which is communicated with the first filter box chamber 2, and the other fan 31 is communicated with the second filter box chamber 5. However, it should be understood that the fan assembly 3 can also be composed of any other suitable components.

[0063] In one embodiment of the present application, Figure 1 and Figure 3 As shown, the side walls of the first filter chamber 2 and the second filter chamber 5 are both provided with a nuclide monitor 7. When in use, the radioactive content in the first filter chamber 2 and the second filter chamber 5 can be detected in real time by the nuclide monitor 7. When the nuclide monitor 7 detects that the radioactivity in the first filter chamber 2 and the second filter chamber 5 exceeds the standard, it indicates that it is not suitable for the staff to open the first filter chamber 2 and the second filter chamber 5 at this time, thereby realizing automatic detection of the situation in the first filter chamber 2 and avoiding manual judgment.

[0064] In one embodiment of the present application, Figure 1 and Figure 4As shown, the radioactive waste gas purification device includes a decay box 8, which is installed on the first filter box chamber 2. An isolation sealing component 9 is arranged between the first filter box chamber 2 and the decay box 8. The isolation sealing component 9 switches between an open state and a closed state, wherein in the open state, the first filter box chamber 2 and the decay box 8 are connected, and in the closed state, the first filter box chamber 2 and the decay box 8 are not connected to each other. When in use, when the first filter box chamber 2 filters the waste gas, the isolation sealing component 9 is in a closed state. When the filter element 6 in the first filter box chamber 2 is full, the isolation sealing component 9 switches to an open state, so that the first filter box chamber 2 and the decay box 8 are connected, and then the filter element 6 in the first filter box chamber 2 can be transferred to the decay box 8, and then the isolation sealing component 9 is converted to a closed state, so that the filter element 6 decays in the decay box 8. When the decay is completed, the staff will transfer the filter element 6 away, further ensuring the safety of the staff. And a new filter element 6 can be quickly installed in the first filter box chamber 2, so that the first filter box chamber 2 can filter the exhaust gas again.

[0065] In the embodiment of the present application, the isolation sealing assembly 9 includes, for example, at least one automatic shielding door, which is disposed at the connection between the first filter box chamber 2 and the decay box 8. However, it should be understood that the isolation sealing assembly 9 may also be composed of any other suitable structure.

[0066] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the radioactive waste gas purification device includes an automatic transfer component 10, which is installed on the top of the decay box 8. When in the open state, the automatic transfer component 10 is suitable for transferring the filter element 6 in the first filter box chamber 2 to the decay box 8. When in use, the filter element 6 in the first filter box chamber 2 can be automatically transferred to the decay box 8 by the automatic transfer component 10, without manual operation, thereby improving the degree of automation and preventing workers from being harmed by radiation.

[0067] In one embodiment of the present application, Figure 1 , Figure 4 and Figure 5 As shown, the automatic transfer component 10 includes a mounting plate 101, a second driving member 102, a suction cup 103, and a rotating member 104; a slide groove 107 matching the mounting plate 101 is provided in the decay box 8, and the mounting plate 101 is slidably connected to the slide groove 107; the second driving member 102 is installed on the mounting plate 101, and the suction cup 103 is connected to the second driving member 102, and the second driving member 102 is used to drive the suction cup 103 to move toward the first filter box chamber 2; the rotating member 104 is connected to the mounting plate 101, and the rotating member 104 is used to drive the mounting plate 101 to slide along the slide groove 107.

[0068] When in use, the second driving member 102 drives the suction cup 103 to move into the first filter box chamber 2, so that the suction cup 103 absorbs the filter element 6 in the first filter box chamber 2, and then the second driving member 102 drives the suction cup 103 to move into the decay box 8, thereby automatically transferring the filter element 6 in the first filter box chamber 2 to the decay box 8. The rotating member 104 drives the mounting plate 101 to slide along the slide groove 107, so that the mounting plate 101 can extend out of the decay box 8, and then the second driving member 102 and the suction cup 103 extend out of the decay box 8, thereby automatically transferring the filter element 6 to the outside of the decay box 8.

[0069] In the embodiment of the present application, the second driving member 102 is, for example, a motor. However, it should be understood that the second driving member 102 may also be any other suitable driving component.

[0070] In one embodiment of the present application, Figure 1 , Figure 4 and Figure 5 As shown, the rotating member 104 includes a rotating shaft 105 and a gear 106. The rotating shaft 105 is rotatably mounted on the decay box 8. One end of the rotating shaft 105 is located outside the decay box 8, and the other end of the rotating shaft 105 is located inside the decay box 8. The gear 106 is connected to the other end of the rotating shaft 105. A rack 107 is provided on the mounting plate 101, and the gear 106 is meshed and connected with the rack 107. When in use, the rotating shaft 105 is rotated by a motor or manually, so that the rotating shaft 105 rotates while driving the gear 106 to rotate, and the gear 106 meshes with the rack 107, so that the gear 106 can drive the mounting plate 101 to move, thereby controlling the mounting plate 101 to slide along the slide groove 107.

[0071] In one embodiment of the present application, Figure 1 and Figure 4 As shown, a monitoring sampling channel 41 is provided on the discharge pipeline 4, one end of the monitoring sampling channel 41 is connected to the discharge pipeline 4, and a second valve 42 is provided on the other end of the monitoring sampling channel 41. When in use, the second valve 42 is opened, and the gas discharged to the outside through the discharge pipeline 4 can be obtained and tested through the second valve 42 and the monitoring sampling channel 41, so as to know whether the gas discharged to the outside meets the requirements. After obtaining the gas in the discharge pipeline 4, the second valve 42 is closed to prevent gas leakage.

[0072] In one embodiment of the present application, Figure 1 and Figure 4 As shown, one end of the discharge pipe 4 is connected to the fan assembly 3, and the other end of the discharge pipe 4 is provided with a rain cap 43. When in use, by providing the rain cap 43 at the other end of the discharge pipe 4, rainwater can be prevented from entering the discharge pipe 4, thereby preventing rainwater from affecting the fan assembly 3 and other components.
