Description

Technical Field

[0001] This utility model relates to the field of purification technology, specifically a high-efficiency radioactive particulate matter filtration and purification device. Background Technology

[0002] The core objective of radioactive particle filtration and purification devices is to efficiently capture, isolate, and safely dispose of radioactive aerosol particles in the air, preventing their release into the environment or work area and protecting personnel and the environment from radiation and pollution.

[0003] A search revealed a radioactive tail gas dust removal device and method with publication number CN115921113B, relating to the field of radioactive waste volume reduction treatment technology. The dust removal device includes: a baghouse dust collector with an exhaust chamber at its upper end; filter bags installed within the baghouse dust collector for filtering particulate matter from the tail gas; a plasma electrostatic dust removal assembly including a cathode plate and an anode plate, respectively disposed on opposite sides of the filter bags; and a dust hopper connected at its upper end to the baghouse dust collector for collecting the particulate matter filtered by the filter bags and the anode plates. High-voltage electrostatic enhancement improves the filtration effect, reduces the load on the filter bags, extends their service life, improves filtration efficiency and effectiveness, and reduces secondary waste generated from bag replacement. The dust removal method, based on the aforementioned dust removal device, can reduce the load on the filter bags and the generation of secondary waste, extend the service life of the filter bags, and improve filtration efficiency and effectiveness.

[0004] The radioactive exhaust gas dust removal device and method in the above technical solution can reduce the load on the filter bag and reduce the generation of secondary waste, extend the service life of the filter bag, and improve the filtration efficiency and filtration effect. However, the treatment of radioactive particles adsorbed on the surface of the electrode plate is not perfect. It only makes them fall off by vibration without detailed treatment. Therefore, we provide a high-efficiency radioactive particle filtration and purification device. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem of not being able to properly handle the radioactive particles adsorbed on the surface of the electrode plate, it simply uses vibration to make them fall off without any detailed treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency radioactive particulate matter filtration and purification device includes: a working platform, a filter shell, a lead plate, and a working housing; the filter shell is fixedly installed on the top of the working platform, the lead plate is fixedly installed inside the filter shell, and the working housing is fixedly installed inside the lead plate; the device further includes: The system includes a cleaning assembly, an electrostatic dust removal assembly, a vibration assembly, a filter assembly, and a conveying assembly.

[0009] As a further embodiment of this utility model: the water pump is fixedly installed at the top of the filter housing, the sprayer is fixedly installed at the top of the working housing, and the spray pipe is fixedly installed at the bottom of the sprayer.

[0010] As a further embodiment of this utility model: the electrostatic dust removal assembly includes an anode plate and a cathode plate, the anode plate being fixedly installed on the inner wall of the working shell, and the cathode plate being fixedly installed on the inner wall of the working shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0021] Example 1

[0022] Please see Figure 1 - Figure 4 This is the first embodiment of the present invention. This embodiment provides a high-efficiency radioactive particulate matter filtration and purification device, including: a working platform 1, a filter shell 2, a lead plate 3, and a working housing 4; the filter shell 2 is fixedly installed on the top of the working platform 1, the lead plate 3 is fixedly installed inside the filter shell 2, and the working housing 4 is fixedly installed inside the lead plate 3, and also includes: The cleaning assembly 5, the electrostatic dust removal assembly 6, the vibration assembly 7, the filter assembly 8, and the conveying assembly 9 are provided. The cleaning assembly 5 is installed on the surface of the filter housing 2 and inside the working housing 4. The electrostatic dust removal assembly 6 is installed on the inner wall of the working housing 4. The vibration assembly 7 is installed on the surface of the filter housing 2 and inside the working housing 4. The filter assembly 8 is installed inside the working housing 4. The conveying assembly 9 is installed on the surface of the working housing 4.

[0023] Specifically, the cleaning assembly 5 includes a circulation pipe 51, a filter box 52, a water pump 53, a sprayer 54, and a spray pipe 55. The circulation pipe 51 is fixedly installed on the surface of the working housing 4, and the filter box 52 is fixedly installed on the top of the working platform 1, located outside the circulation pipe 51. The water pump 53 is fixedly installed on the top of the filter housing 2, the sprayer 54 is fixedly installed on the top of the working housing 4, and the spray pipe 55 is fixedly installed on the bottom of the sprayer 54.

[0024] Furthermore, an alkaline solution is sprayed into the working shell 4 through the spray pipe 55 below the sprayer 54 to clean the various parts inside the working shell 4. This washes the radioactive particles on the surface of the parts to the bottom of the working shell 4, where they are fixed in the filter box 52 for collection. The recovered alkaline solution can then be sprayed again by the water pump 53.

[0025] Specifically, the electrostatic dust removal assembly 6 includes an anode plate 61 and a cathode plate 62. The anode plate 61 is fixedly installed on the inner wall of the working shell 4, and the cathode plate 62 is fixedly installed on the inner wall of the working shell 4.

[0026] Furthermore, by discharging through the cathode plate 62, smaller radioactive particles are adsorbed onto the anode plate 61, thereby enabling the adsorption treatment of radioactive particles.

[0027] In use, lead plate 3 provides protection against radioactive particles. Alkaline solution is sprayed into the working shell 4 through spray pipe 55 below sprayer 54 to clean the various parts inside the working shell 4. The cleaned solution falls to the bottom of the working shell 4 under gravity and is then recovered by water pump 53 through circulation pipe 51 from the bottom of the working shell 4 back to the sprayer 54 at the top of the working shell 4. During the recovery process, radioactive particles in the solution are blocked by the ion membrane inside the filter box 52 and remain inside the filter box 52 for collection. When radioactive particulate gas enters the device, the radioactive particulate gas first passes through the electric field of electrostatic dust removal component 6. In the electric field of electrostatic dust removal component 6, cathode plate 62 discharges, causing fine particles in the gas to become charged, which is conducive to particle aggregation. Under the action of electrostatic force, the particles are adsorbed onto anode plate 61, that is, anode plate 61 serves as a dust collection electrode.

[0028] In summary, by spraying an alkaline solution into the working shell 4 through the spray pipe 55 below the sprayer 54, the various parts inside the working shell 4 are cleaned. This washes the radioactive particles on the surface of the parts to the bottom of the working shell 4, where they are fixed in the filter box 52 for collection. The recovered alkaline solution can be sprayed again by the water pump 53 and discharged through the cathode plate 62, causing smaller radioactive particles to be adsorbed onto the anode plate 61, thus achieving adsorption treatment of radioactive particles.

[0029] Example 2

[0030] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0031] Specifically, the vibration assembly 7 includes a support plate 71, a vibration motor 72, a vibration shaft 73, a vibration support column 74, and a vibration plate 75. The support plate 71 is fixedly installed on the surface of the filter housing 2, and the vibration motor 72 is fixedly installed on the top of the support plate 71. The vibration shaft 73 is fixedly installed on the output end of the vibration motor 72, the vibration support column 74 is fixedly installed on the surface of the vibration shaft 73, and the vibration plate 75 is fixedly installed on the end of the vibration support column 74.

[0032] Furthermore, the vibration motor 72 drives the vibration shaft 73 to rotate, thereby causing the vibration plate 75 to continuously strike the anode plate 61 and the cathode plate 62, causing the radioactive particles on the surface of the anode plate 61 and the cathode plate 62 to fall into the solution at the bottom for subsequent collection.

[0033] Specifically, the filter assembly 8 includes a preliminary filter plate 81 and a ULPA filter plate 82. The preliminary filter plate 81 is fixedly installed on the inner wall of the working shell 4 on the surface of the anode plate 61, and the ULPA filter plate 82 is fixedly installed on the inner wall of the working shell 4 on the surface of the cathode plate 62.

[0034] Furthermore, the radioactive particulate matter is further processed by the preliminary filter plate 81 to remove larger particles from the air, preventing them from clogging or damaging the expensive ULPA filter plate 82 too quickly and extending its service life. The ULPA filter plate 82 captures particles through interception, inertial impaction, and diffusion effects, thus further filtering the radioactive particulate matter.

[0035] Specifically, the conveying assembly 9 includes an air inlet pipe 91 and an air outlet pipe 92. The air inlet pipe 91 is fixedly installed inside the working shell 4, and the air outlet pipe 92 is fixedly installed inside the working shell 4.

[0036] Furthermore, radioactive particulate gas is introduced into the device for processing through the inlet pipe 91, and the purified gas is discharged from the device through the outlet pipe 92.

[0037] In use, the vibration motor 72 on the support plate 71 on the surface of the filter housing 2 drives the vibration shaft 73 to rotate, causing the vibration support 74 and the vibration plate 75 to rotate. The vibration plate 75 strikes the anode plate 61 and the cathode plate 62. The particulate gas enters the working housing 4 through the air inlet pipe 91, is initially filtered by the preliminary filter plate 81, and then undergoes detailed filtration through the ULPA filter plate 82 after electrostatic dust removal. When the vibration plate 75 strikes the anode plate 61 and the cathode plate 62, the anode plate 61 and the cathode plate 62, as well as the preliminary filter plate 81 and the ULPA filter plate 82 fixedly installed on their surfaces, are struck, causing the radioactive particles remaining on the surface of the parts to be shaken off.

[0038] In summary, the initial filter plate 81 treats radioactive particulate matter, removing larger particles from the air to prevent them from clogging or damaging the expensive ULPA filter plate 82 too quickly, thus extending its service life. The ULPA filter plate 82 captures particles through interception, inertial impaction, and diffusion effects. Further filtration of the radioactive particulate matter involves introducing radioactive particulate gas into the device through the inlet pipe 91 for processing, and then discharging the purified gas from the device through the outlet pipe 92.
