Nanoscale silver difluoride preparation device and process

The invention discloses a nanoscale silver difluoride preparation device and process, and belongs to the technical field of fluorine-containing industrial catalyst preparation. The preparation device comprises a fluorination reaction cavity part, a silver steam generator part and a gas source and pressure control part. According to the device, the temperature of the silver wire is increased through microsecond intense pulse to be vaporized, then silver steam is generated, the silver steam reacts with fluorine gas to prepare nano-scale silver difluoride particles, and the silver difluoride particles are filtered and collected through a microfiltration membrane. According to the process, high-purity silver wires and fluorine gas are adopted as reaction raw materials, the particle size distribution range of silver difluoride particles is small, the preparation efficiency is high, and no side reaction exists. And the output of the nano silver difluoride can be controlled by adjusting the conveying speed of the si
