Description

Technical Field

[0001] This utility model relates to the field of fluorine purification technology, specifically a fluorine purification device. Background Technology

[0002] Fluorine (chemical formula: F₂F₂) is a colorless gas with a pungent odor and is highly reactive. It is a diatomic molecule of element fluorine, belonging to the halogen group of elements, and has extremely high electronegativity and reactivity. Fluorine purification is a crucial step to ensure that the fluorine gas has high purity to meet the needs of industry and scientific research. The purification process mainly includes removing impurities such as moisture, oxygen, carbon dioxide, and heteroatoms to prevent the reaction from corroding equipment or affecting its use. Fluorine purification equipment is mainly used to remove impurities (such as moisture, heteroatoms, and other residual gases) from fluorine gas to ensure that the purity of fluorine gas meets industrial or scientific research requirements.

[0003] Traditional fluorine purification devices have poor adsorption and filtration functions during purification, and unreasonable filter layer design leads to the residue of solid impurities and particles. They cannot completely remove pollutants and are not easy to completely intercept fine particles and solid impurities. As a result, pollutants remain in the fluorine gas, and solid impurities and particles cannot be completely removed, affecting the purity of the fluorine gas and its safety in use.

[0004] Therefore, this invention provides a device for fluorine purification to solve the above-mentioned problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This invention features a simple structure and convenient operation. When purifying fluorine gas, the spiral outer shell allows the fluorine gas to flow slowly.

[0023] 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.

[0024] This invention provides a device for purifying fluorine gas, such as... Figures 1-5 As shown, this fluorine purification device includes a tank 1, a processing mechanism fixedly installed inside the tank 1, a groove on the outer surface of the tank 1, a noise-reducing plate 2 fixedly connected inside the groove, a transmission mechanism fixedly connected to the bottom of the outer surface of the tank 1, and a slot for fixing the feed pipe 3 on the upper surface of the tank 1. The noise-reducing plate 2 can reduce the noise transmitted from inside the tank 1, thus playing a noise reduction role. Fluorine gas is poured into the tank 1 from the feed pipe 3, and the fluorine gas is purified by the processing mechanism. The multi-layer filter screen 7, combined with the spiral flow, can effectively intercept impurities of different particle sizes in multiple stages to obtain higher purity fluorine gas. Subsequently, the fluorine gas is filtered and circulated again by the transmission mechanism, and the fluorine gas flows into the purification tank 14 and flows out from the outlet pipe 15.

[0025] The processing mechanism includes a spiral shell 4, one end of which is fixedly connected to the inside of the tank 1. The inside of the spiral shell 4 is a layered groove, and heating tubes 5 are fixedly connected to the top, middle and bottom of the layered groove. When purifying fluorine gas, the fluorine gas can flow slowly through the spiral shell 4. The spiral flow increases the residence time of the gas in the filter layer, improves the contact efficiency between impurities and filter materials, and improves the purification effect. The multi-layer filter screen 7, in conjunction with the spiral flow, can effectively intercept impurities of different particle sizes in multiple stages to obtain higher purity fluorine gas.

[0026] A heat insulation tube 6 is fixedly connected to one end of the heating tube 5, and a filter screen 7 is fixedly connected to the outer surface of the spiral shell 4. The filter screen 7 is divided into three groups. Multiple groups of filter screens 7 can improve the filtration effect and enhance the purity of fluorine gas.

[0027] The transmission mechanism includes a transmission pipe 8, one end of which is fixedly connected to the bottom of the outer surface of the tank 1. A control valve 9 is fixedly connected to the outer surface of the transmission pipe 8. An A filter screen 10 is fixedly connected inside the transmission pipe 8. A spiral tube 11 is fixedly connected to one side of the A filter screen 10. A B filter screen 12 is fixedly connected to one end of the spiral tube 11. The purified fluorine gas flows inside the transmission pipe 8. When the control valve 9 is opened, the fluorine gas flows from the transmission pipe 8 into the purification tank 14. When passing through the transmission pipe 8, it is filtered again by the A filter screen 10 and the B filter screen 12. During filtration, it flows slowly in a spiral manner through the spiral tube 11 again, which improves the purification effect.

[0028] An insulation layer 13 is fixedly connected to the interlayer of the tank body 1. The outer surface of the insulation layer 13 is coated with a waterproof layer. The insulation layer 13 has the effect of heat preservation, keeping the temperature inside the tank body 1 uniform and stable, and improving the fluorine purification effect.

[0029] The other end of the transmission pipe 8 is fixedly connected to a purification tank 14. An outlet pipe 15 is fixedly connected to the bottom of the outer surface of the purification tank 14. A temperature sensor 16 is fixedly connected to the middle of the outer surface of the purification tank 14. The purified fluorine gas enters the purification tank 14. The temperature inside the purification tank 14 is monitored by the temperature sensor 16. After reaching a suitable temperature, the fluorine gas inside the purification tank 14 is released from the outlet pipe 15.

[0030] Specifically, fluorine gas is poured into tank 1 through feed pipe 3. After the fluorine gas enters tank 1, heating pipe 5 is activated. Heating pipe 5 is kept warm through insulation pipe 6, and the heat is transferred to the spiral outer shell 4 to increase the temperature inside tank 1. The fluorine gas flows slowly in a spiral pattern along the spiral outer shell 4, and then flows onto the filter screen 7. The filter screen 7 is divided into three groups to achieve a multi-layer filtration effect. Subsequently, the multi-layer filter screen 7, in conjunction with the spiral flow, can effectively intercept impurities of different particle sizes at multiple stages, obtaining higher purity fluorine gas. The purified fluorine gas flows in the transfer pipe 8. The control valve 9 is opened to allow the fluorine gas to flow from the transfer pipe 8 into the purification tank 14. As it passes through the transfer pipe 8, it is filtered again by filter screen A 10 and filter screen B 12. During filtration, it flows slowly in a spiral manner through the spiral tube 11 to improve the purification effect. Subsequently, the purified fluorine gas enters the purification tank 14. The temperature inside the purification tank 14 is monitored by the temperature sensor 16. Once the appropriate temperature is reached, the fluorine gas in the purification tank 14 is released from the outlet pipe 15.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
