Description

Technical Field

[0001] This utility model relates to the field of fluorine chemical purification technology, and in particular to a high-efficiency hydrogen fluoride purification device. Background Technology

[0002] Currently, hydrogen fluoride, as an important inorganic fluoride, has wide applications in various fields such as electronics, medicine, metallurgy, and chemicals. Especially in the preparation of high-purity electronic-grade hydrogen fluoride, the requirements for purity and impurity control are extremely high. Hydrogen fluoride reacts readily with moisture and oxidizing impurities, exhibiting high corrosiveness and volatility. Therefore, the purification process requires a high degree of technical coordination between temperature control, filtration, and condensation structures.

[0003] Regarding the aforementioned issues, traditional hydrogen fluoride purification devices mostly employ a method of heating and distilling the gas in a tank, then guiding the gas through a condensation system to recover the liquid product. Condensation largely relies on an external cooling water source or cooling pipelines. In most devices, the gas-liquid mixture directly enters a collector for settling. Common equipment includes simple piping connections and fixing mechanisms for connection to processing systems or transfer modules.

[0004] However, these existing devices have several problems in practical use. First, some devices are cumbersome in terms of connection and sealing operations, which is not conducive to efficient operation by workers, especially when frequently loading and unloading particulate materials, as the device is inconvenient to open and close and cannot be locked securely. Second, most filter modules are fixed structures, which limits the filtration accuracy and lacks coordination with the cooling structure, making it difficult to simultaneously achieve impurity isolation and temperature-controlled purification.

[0005] To address the above problems, a high-efficiency hydrogen fluoride purification device is proposed. Utility Model Content
