Description

Technical Field

[0001] This utility model relates to the field of iodine purification filter technology, specifically a high-efficiency iodine purification filter. Background Technology

[0002] Iodine purification filters are primarily used to remove harmful gases such as methyl iodine, elemental iodine, and particulate iodine from the air, controlling their concentration below the standard limits. They are core equipment for removing radioactive iodine pollutants from nuclear power plant process exhaust and ventilation. Iodine purification filters primarily filter air pollutants through internal filter materials, mainly coconut shell activated carbon. Coconut shell activated carbon is a porous carbonized material made from coconut shells through high-temperature calcination, carbonization, activation, crushing, and fine sieving. Its well-developed internal pore structure and strong adsorption capacity enable it to remove heavy metals and acid ions from water, increase water activation, protect human health, and promote metabolism.

[0003] However, existing iodine purification filters have the following problems during use: Air to be purified is introduced through pipes into the internal cavity of the filter box or cartridge within the iodine purification filter. The filter material then adsorbs and purifies the air. During use, the portion located inside the filter box or cartridge often has more comprehensive contact with the air, achieving the purpose of absorbing pollutants. The main pollutants also concentrate on the inner side of the filter box or cartridge, while the outer part has limited contact with the air, resulting in insufficient filtration and affecting the service life of the filter box or cartridge. Therefore, a corresponding technical solution needs to be designed to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency iodine purification filter, which solves the technical problem that the air to be purified is introduced into the internal cavity of the filter box or filter cartridge of the iodine purification filter through a pipe, and the air is purified by adsorption through the filter material. During use, the part located on the inside of the filter box or filter cartridge often has more comprehensive contact with the air, so as to achieve the purpose of absorbing pollutants. The main pollutants are also concentrated on the inside of the filter box or filter cartridge, while the part on the outside of the filter box or filter cartridge has limited contact with the air, so its filtration performance cannot be fully utilized, which affects the service life of the filter box or filter cartridge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency iodine purification filter, comprising a filter body and a diversion purification assembly installed on the filter body. The filter body includes a shell, an inlet pipe, an exhaust pipe, a sealing gasket, and a filter box. The inlet pipe and the exhaust pipe are respectively installed at the left and right ends of the shell, and both are equipped with valves. The sealing gasket is attached to the inner wall of the shell. The filter box is built into the shell and includes a filter cylinder and an air guide channel opened inside the filter cylinder. The left end of the air guide channel is connected to... The intake pipe is connected to the exhaust pipe, which is fixed to the right end of the filter cartridge. The diversion purification assembly includes a diversion pipe, an arc-shaped side plate, a guide pipe, and branch pipes. The diversion pipe is divided into two groups and connected to the intake pipe. The diversion pipe is also equipped with a valve. The end of the diversion pipe is connected to the arc-shaped side plate. The two groups of arc-shaped side plates are respectively attached to the outer surface of the filter cartridge. The guide pipe is built into the arc-shaped side plate. The branch pipe is divided into several groups and evenly installed on the guide pipe. Several groups of exhaust holes are evenly opened on the surface of the branch pipe.

[0006] In a preferred embodiment of this utility model, the surface of the exhaust pipe is symmetrically provided with air guide ports, which are located on the outside of the filter cylinder.

[0007] In a preferred embodiment of this utility model, the filter cartridge has a cylindrical structure and is made of activated carbon material, and the surface of the filter cartridge has a porous structure.

[0008] In a preferred embodiment of this utility model, the arc-shaped side plate has the same curvature as the outer surface of the filter cylinder and is attached to the surface of the filter cylinder.

[0009] In a preferred embodiment of this utility model, two sets of angle steels are symmetrically installed at the bottom of the outer shell, and the angle steels are in an L-shaped structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model optimizes the existing structure of iodine purification filters by equipping them with a diversion purification component. When the adsorption performance of the inner side of the filter material in contact with the air decreases due to prolonged use, the diversion purification component can guide the air to the outside of the filter box or filter cartridge. By diverting the air to the outside and filtering it through the outer surface of the filter material, the air can be filtered. This design can greatly improve the service life of the filter box or filter cartridge inside the iodine purification filter.

[0012] 2. The iodine purification filter designed in this utility model can effectively improve the service life and performance of the filter box or filter cartridge inside the iodine purification filter. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 This utility model provides a technical solution: a high-efficiency iodine purification filter, comprising a filter body and a diversion purification assembly installed on the filter body. The filter body includes a housing 1, an inlet pipe 2, an exhaust pipe 3, a sealing gasket 4, and a filter box 5. The inlet pipe 2 and the exhaust pipe 3 are respectively installed at the left and right ends of the housing 1, and both are equipped with valves 6. The sealing gasket 4 is attached to the inner wall of the housing 1. The filter box 5 is built into the housing 1 and includes a filter cylinder 7 and an air guide channel 8 opened inside the filter cylinder 7. The left end of the air guide channel 8 is connected to the inlet pipe 2. The exhaust pipe 3 is fixed to the right end of the filter cylinder 7. The diversion purification assembly includes a diversion pipe 9, an arc-shaped side plate 10, a diversion pipe 11, and a branch pipe 12. The diversion pipe 9 is divided into two groups and connected to the air inlet pipe 2. The diversion pipe 9 is also equipped with a valve 6. The end of the diversion pipe 9 is connected to the arc-shaped side plate 10. The two groups of arc-shaped side plates 10 are respectively attached to the outer surface of the filter cylinder 7. The diversion pipe 11 is built into the arc-shaped side plate 10. The branch pipe 12 is divided into several groups and evenly installed on the diversion pipe 11. Several groups of exhaust holes 13 are evenly opened on the surface of the branch pipe 12.

[0018] Further improvements, such as Figure 2 As shown, the surface of the exhaust pipe 3 is symmetrically provided with air guide ports 14. The air guide ports 14 are located on the outside of the filter cartridge 7. The air purified by the filter cartridge 7 is introduced through the air guide ports 14 and discharged outward along the exhaust pipe 3.

[0019] Further improvements, such as Figure 2As shown, the filter cartridge 7 has a cylindrical structure and is made of activated carbon material. The surface of the filter cartridge 7 has a porous structure, and the activated carbon used is coconut shell activated carbon, which has better adsorption and purification functions.

[0020] Further improvements, such as Figure 2 As shown, the arc-shaped side plate 10 has the same curvature as the outer surface of the filter cylinder 7 and is attached to the surface of the filter cylinder 7. The air to be filtered is guided through the exhaust hole 13 of the branch pipe 12 on the arc-shaped side plate 10 and first filtered through the outer surface of the filter cylinder 7.

[0021] Specifically, two sets of angle steels 15 are symmetrically installed at the bottom of the outer casing 1. The angle steels 15 have an L-shaped structure, which facilitates the installation and fixing of the filter.

[0022] In use: When air filtration and purification are required, first adjust valve 6 on the diverter pipe 9 to the closed state. Then, the air to be purified is introduced into the air guide cavity 8 inside the filter cartridge 7 through the air inlet pipe 2. The air passes through the filter cartridge 7 to achieve the purpose of air purification. The purified air is introduced into the exhaust pipe 3 through the air guide port 14 on the surface of the exhaust pipe 3 and discharged externally. During long-term use, a large amount of dirt will accumulate on the inside of the filter cartridge 7, resulting in a decrease in filtration effect. Smaller pollutants are often retained on the outside of the filter cartridge. At this time, the operator closes the valve at the inside of the air inlet pipe 2 and opens valve 6 on the diverter pipe 9. The air is introduced into the branch pipe 12 along the diverter pipe 9 and the guide pipe 11. The air is introduced from the outer surface of the filter cartridge 7 through the exhaust port 13 on the branch pipe 12 to achieve the purpose of air purification. By adjusting the air introduction direction as described above, the overall filtration capacity of the filter cartridge 7 can be fully utilized, effectively improving the service life and effect of the filter box or filter cartridge inside the iodine purification filter.
