[0002] A high-temperature purification furnace is a device used for the purification of carbon-based materials such as graphite and graphite felt. Because a certain degree of vacuum is required during the purification process, the insulation felt or materials within the furnace generate a large amount of dust, such as carbon fibers, when the vacuum system draws air from the insulation felt or materials. This dust is then adsorbed onto the inner wall of the exhaust pipe.
