| titleOfInvention | A kind of method and device for removing HF in fluorine gas |
| abstract | The invention provides a method and a device for removing HF from fluorine gas. The method comprises the following steps: passing the fluorine gas prepared from an electrolytic cell into a condenser body, and performing low-temperature primary condensation treatment to remove 90% of the fluorine gas contained in the fluorine gas. % HF, pass the condensed fluorine gas into the purifier group, and use the chemical adsorption of NaF adsorbent to HF to remove HF in the fluorine gas. When the adsorption capacity of the NaF adsorbent is saturated, the NaF adsorbent is subjected to high temperature Activation and regeneration treatment is used for tail gas treatment of fluorine gas and HF generated in the regeneration process of NaF adsorbent. The device includes electrolytic cell, condenser group, purifier group, F2 gas collecting cylinder, venting reactor, primary water washing tower, alkali washing tower, secondary water washing tower and exhaust device. The invention has reasonable process method, reasonable device structure, reliable control performance and safety performance, and can realize continuous production and interlocking automatic control. |
