[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-5 As shown, this utility model provides a medical radioactive gas filtration device, including a filter box 1. An observation window 2 is embedded on the left side of the front end of the filter box 1. An air inlet 3 is fixedly provided on the left end of the filter box 1. Supports 4 are symmetrically fixed on both sides of the lower end of the filter box 1. A spray mechanism 5 is provided on the left side inside the filter box 1. A filtration mechanism 6 is provided on the right side inside the filter box 1. A funnel 7 is fixedly provided on the lower left end of the filter box 1. A drain pipe 8 is fixedly provided at the bottom of the funnel 7. An exhaust port 9 is fixedly provided on the right end of the filter box 1.

[0025] A partition 10 is fixedly installed in the middle of the inner cavity of the filter box 1, and multiple sets of connecting holes 11 are opened through the surface of the partition 10.

[0026] A solenoid valve is fixedly installed on the drain pipe 8.

[0027] In this scheme, the opening and closing of the drain pipe 8 can be controlled by the solenoid valve installed on the drain pipe 8, thereby facilitating the discharge of waste liquid. The observation window 2 allows the operator to easily check the spraying situation, and the connecting hole 11 facilitates the smooth passage of the radioactive gas after spraying through the two sets of filter plates 63.

[0028] like Figures 3-4As shown in the figure, the spraying mechanism 5 includes a first mounting seat 51. The bottom end of the first mounting seat 51 is fixedly connected to the left side of the rear end of the filter box 1. The upper end of the first mounting seat 51 is fixedly connected to a liquid tank 52. Above the first mounting seat 51, a second mounting seat 53 is fixedly installed. Inside the second mounting seat 53, a liquid pump 54 is fixedly connected. The upper end of the liquid pump 54 is fixedly connected to a communicating conduit 55. On the inner wall of the upper left end of the filter box 1, multiple hanging plates 56 are fixedly connected. The lower end of the hanging plate 56 is fixedly connected to a flow splitting frame 57. The lower end of the flow splitting frame 57 is fixedly connected to multiple communicating nozzles 58.

[0029] The liquid tank 52 is connected to the liquid pump 54, and the top end of the conduit 55 extends into the filter box 1.

[0030] The top end of the conduit 55 is fixedly connected to the upper end of the flow splitting frame 57 and is in communication therewith. The nozzles 58 are equidistantly distributed at the lower end of the flow splitting frame 57, and the flow splitting frame 57 is arranged in a "king" shape.

[0031] In this solution, during the spraying process, the radioactive gas is in full contact with the spraying solution. Large particle impurities such as dust and particles carried in the gas can be captured and washed away by the spraying solution, which can prevent these large particles from entering the activated carbon filter plate 63 and avoid blocking the pores of the filter plate 63, thereby extending the service life of the activated carbon filter plate 63 and maintaining its good adsorption performance. At the same time, the spraying solution can select a targeted solvent according to the composition of the radioactive gas, which can initially remove some radioactive substances or other harmful gases in the gas and reduce the concentration of pollutants in the gas.

[0032] As Figure 5 As shown in the figure, the filtering mechanism 6 includes a through port 61. The through port 61 is connected through the right side of the front end of the filter box 1. On the upper and lower inner walls of the right end of the filter box 1, clamping rails 62 are symmetrically and fixedly installed. Inside the clamping rails 62, a filter plate 63 is slidably connected. The front end of the filter plate 63 is fixedly connected to a fixing block 64. An adhesive gasket 65 is bonded to the outside of the fixing block 64. The front end of the fixing block 64 is fixedly installed with an end plate 66. On both the upper and lower sides of the end plate 66, clamping columns 67 are symmetrically and fixedly installed. On the right side of the front end of the filter box 1, damping rotating shafts 68 are symmetrically and fixedly installed. Outside the damping rotating shafts 68, a clamping plate 69 is rotatably installed.

[0033] The through port 61 is movably connected to the fixing block 64, and the adhesive gasket 65 is in contact with the inner wall of the through port 61. The clamping rails 62 are arranged in a "C" shape.

[0034] A clamping opening is provided at the top end of the clamping plate 69, and the clamping opening is matched with the clamping column 67 and is movably installed.

[0035] In this solution, after the end plate 66 is installed in place, the clamping plate 69 can accurately limit the end plate 66 through the tight clamping connection with the clamping column 67, making it not easy to slide off during use and ensuring the overall stability and reliability.

[0036] The working principle of this medical radioactive gas filtration device will be explained in detail below.

[0037] like Figures 1-5 As shown, in use, the medical radioactive gas filtration device allows radioactive gas to enter the left side of the filter box 1 through the inlet 3. At this point, the liquid pump 54 is activated, drawing out the solution from the liquid tank 52 and pumping it through the conduit 55 to the distribution frame 57. Finally, the solution is sprayed out through multiple equally spaced nozzles 58, allowing it to contact the radioactive gas. This washes away large particles of impurities in the gas and adsorbs radioactive substances. The waste liquid from the wash falls into the funnel 7 below for storage, while the sprayed radioactive gas is then... The gas enters the right side of the filter box 1 through the connecting hole 11. The radioactive gas can be filtered by two sets of filter plates 63 in sequence and discharged through the exhaust port 9, so that the discharged gas can meet the emission standards. When the filter plate 63 needs to be replaced or cleaned, the clamping plate 69 can be rotated to separate the clamping plate 69 from the clamping post 67. At this time, the end plate 66 can be pulled outward to easily pull the filter plate 63 out of the filter box 1, so as to facilitate its replacement or cleaning. Conversely, the filter plate 63 can be inserted into the clamping rail 62 and the clamping plate 69 can be clamped onto the clamping post 67, so as to complete the installation of the filter plate 63. At the same time, the filter plate 63 is not easy to fall off.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
