Description

Technical Field

[0001] This utility model belongs to the field of thorium tetrafluoride preparation, specifically a gas purification device for thorium tetrafluoride preparation. Background Technology

[0002] Thorium tetrafluoride, as an important inorganic compound, has shown broad application prospects in many fields such as nuclear industry, materials science, and chemical research due to its unique physicochemical properties. Its preparation process usually involves complex chemical reactions and has extremely high requirements for the purity of raw materials and reaction conditions.

[0003] In existing technologies, the preparation process of thorium tetrafluoride typically includes multiple steps such as raw material preparation, reaction control, product collection, and subsequent processing. First, high-purity fluorine gas or other fluorine-containing gases are required as the main raw material, along with other auxiliary raw materials and catalysts. In a specific reaction vessel, the raw material gases undergo a chemical reaction by precisely controlling reaction conditions such as temperature and pressure to generate thorium tetrafluoride. During this process, even slight fluctuations in reaction conditions can affect the purity and yield of the product. After the reaction is completed, the generated thorium tetrafluoride is separated from the reaction mixture using specific separation and purification techniques and undergoes preliminary purification. As needed, the preliminarily purified thorium tetrafluoride is further refined and processed to obtain a product that meets the requirements of a specific application.

[0004] However, the preparation of thorium tetrafluoride usually requires high-purity fluorine gas or other fluorine-containing gases as raw materials. However, in practical applications, the raw material gases often contain various impurities, such as moisture, dust and other harmful gases. The presence of these impurities will directly affect the preparation reaction of thorium tetrafluoride, which can easily lead to a decrease in reaction rate and yield, and may even trigger side reactions and generate unwanted byproducts.

[0005] In summary, this invention provides a gas purification device for the preparation of thorium tetrafluoride to solve the above problems. Utility Model Content

[0025] Example 1

[0026] like Figure 1-6 As shown, this is the first embodiment of the present invention, which provides a gas purification device for the preparation of thorium tetrafluoride, including...

[0027] The first processing unit 100 includes a housing 110, a connecting cylinder 120 fixedly connected to the bottom of the inner cavity of the housing 110, a connecting frame 130 disposed at the upper end of the inner cavity of the housing 110, an activated carbon adsorption mesh 140 disposed in the inner cavity of the connecting frame 130, and a HEPA filter 150 fixedly connected to the bottom of the connecting frame 130.

[0028] The second processing unit 200 includes a cover 210, a cap 220 movably connected to the top of the cover 210, a mesh frame 230 fixedly connected to the bottom of the cap 220, and a desiccant disposed in the inner cavity of the mesh frame 230.

[0029] like Figure 1-6As shown, the raw material gas enters the connecting cylinder 120 and then rises into the inner cavity of the housing 110. During the ascent, the raw material gas passes through the HEPA filter 150, which filters out fine particulate matter. The filtered raw material gas then enters the inner cavity of the housing 110, where the activated carbon adsorption mesh 140 adsorbs dust and some harmful gases, thus achieving primary purification of the raw material gas. The gas that has passed through the first stage of purification enters the second processing unit 200, where it passes through the mesh frame 230 and the desiccant inside. The desiccant removes moisture from the gas, thus achieving secondary purification of the raw material gas. This ensures efficient purification of the raw material gas, improves its quality, and effectively prevents the raw material gas from affecting the subsequent reaction of thorium tetrafluoride preparation.

[0030] Example 2

[0031] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] In this embodiment, a sealing gasket 213 is fixedly connected to the inner wall of the cover 210, the bottom of the cover 220 extends into the inner cavity of the cover 210, and the inner wall of the sealing gasket 213 contacts the cover 220. A handle is fixedly connected to the top of the cover 220.

[0033] The lower end of the inner cavity of the cover 210 is fixedly connected to the limiting strip 212. The cover 210 is fitted onto the upper end of the surface of the cover 110. The top of the cover 110 is in contact with the limiting strip 212, and the surface of the cover 110 is in contact with the sealing gasket 213.

[0034] like Figure 1-3 As shown, by fixing a sealing gasket 213 to the inner wall of the cover 210, when the cover 220 is closed, its surface is in close contact with the sealing gasket 213. The elastic deformation of the sealing gasket 213 fills any possible small gaps, thereby effectively preventing gas leakage and enhancing the sealing performance of the device. The movement of the housing 110 within the cover 210 ensures a stable connection and accurate positioning between the two, allowing the housing 110 to maintain a stable position within the cover 210. The contact between the surface of the housing 110 and the sealing gasket 213 further ensures the sealing performance of the connection between the housing 110 and the cover 210.

[0035] Example 3

[0036] Reference Figure 3-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] In this embodiment, the front of the cover 210 is connected to the gas outlet pipe 211, and one end of the gas outlet pipe 211 is connected to the reaction vessel. The front of the connecting cylinder 120 is connected to the gas inlet pipe 121, and the other end of the gas inlet pipe 121 is connected to the raw material gas storage tank.

[0038] A connecting rod 111 is fixedly connected to the bottom of the inner cavity of the cover 110, and a bolt sleeve 131 is movably connected to the top of the connecting frame 130 through a bearing. The connecting rod 111 passes through the inner cavity of the bolt sleeve 131 and is threadedly connected to the inner cavity of the bolt sleeve 131.

[0039] like Figure 3-6 As shown, the purified gas is directly delivered to the reaction vessel through the exhaust pipe 211 connected to the front of the cover 210, providing pure raw material gas for the subsequent preparation reaction and ensuring the continuity and efficiency of gas purification. The raw material gas to be purified can smoothly enter the purification process through the intake pipe 121 on the front of the connecting cylinder 120, providing a stable source of air for the purification process. The threaded connection between the connecting rod 111 and the bolt sleeve 131 allows the connecting frame 130 and the activated carbon adsorption net 140 and HEPA filter 150 on it to be easily disassembled and assembled, facilitating the regular replacement and cleaning of the filter and ensuring the purification effect.

[0040] In use, first pull the cap 220, which will detach from the inner cavity of the cover 210. Place an appropriate amount of desiccant into the inner cavity of the mesh frame 230, then close the cap 220, ensuring it is tightly secured to the cover 210, with the sealing gasket 213 ensuring a tight seal. Next, connect the inlet pipe 121 to the raw material gas source and the outlet pipe 211 to the subsequent reaction equipment. Then, turn on the raw material gas source, allowing the raw material gas to enter the connecting cylinder 120 through the inlet pipe 121, and then rise into the inner cavity of the cover 110. During this ascent, the raw material gas passes through the HEPA filter 150, filtering out fine particulate matter. The filtered raw material gas then enters the inner cavity of the cover 110. Inside the housing 110, the activated carbon adsorption mesh 140 adsorbs dust and some harmful gases from the gas, thus achieving primary purification of the raw material gas. The gas after primary purification enters the second processing unit 200, where it passes through the mesh frame 230 and the desiccant inside. The desiccant removes moisture from the gas, thus achieving secondary purification of the raw material gas. Finally, the gas after two stages of purification is discharged to the reaction vessel through the outlet pipe 211 for use in the subsequent thorium tetrafluoride preparation reaction. By ensuring efficient purification of the raw material gas, the quality of the raw material gas is improved, effectively preventing the raw material gas from affecting the subsequent thorium tetrafluoride preparation reaction.
