摘要

摘要: 一种新型连续式高温石墨提纯热工装备，通过高温传动装置驱动石墨粉在提纯过程中运动，实现工业化连续提纯。该设备的自动进出料技术保证石墨在提纯过程中不断供给与收集，且反应气体不泄露；炉膛采用多区控温，温度分布均匀性控制为±5℃；保温材料采用迷宫式错层搭接结构，防止热散失；尾气处理系统采用四级收集装置，对尾气、焦油、粉尘等进行分开收集处理。将该石墨提纯炉应用于高温反应法石墨提纯，石墨的纯度从初始的88.2%提高至99.5%，提纯速率为90 kg/h，达到了连续量产高纯石墨的要求，对开发下一代工业化石墨提纯装备和技术具有重要的实际意义。

Abstract: A new continuous high-temperature reactor for graphite purification using Freon-12 up to 2 600℃ was designed with a collection and disposal device for the exhaust such as off-gases, tar and dust. The reactor had an automatic graphite delivery system and amulti-zone temperature control system for feed-in, heating, reaction, cooling and feed-out regions that were controlled within ±5℃. The configuration of heat-insulating materials use da labyrinthine connection for irregularly-positioned multi-layer insulating pieces to isolate air and to prevent heat dissipation. Using this reactor the purity of the graphite can be increased from 88.2 to 99.5% with a production capacity of 90 kg/h.
