Graphite purification equipment and process gas shunt device and method

Abstract

The invention discloses a process gas shunt device. The process gas shunt device comprises a muffle (22), a shunt disc (24) and shunt pipes (23), wherein the shunt disc (24) is arranged at the bottom of the muffle (22), and the shunt pipes (23) are mounted on the shunt disc (24) and are located at the upper part of the shunt disc (24); an air inlet cavity (25) is defined by the shunt disc (24) and the bottom region of the muffle (22); an air inlet (26) is formed in the air inlet cavity (25); the air inlet cavity (25) is communicated with the shunt pipes (23); air holes (21) are formed in the shunt pipes (23). The invention further discloses a process gas shunt method. According to the process gas shunt device and the process gas shunt method, the problem that process gas is not uniformly distributed in a reaction region in a graphite purification process is effectively solved. The invention further discloses graphite purification equipment comprising the process gas shunt device.

Description

technical field [0001] The invention relates to the technical field of graphite purification equipment, in particular to a process gas splitting device and method. In addition, the present invention also relates to a graphite purification equipment comprising the above process gas distribution device. Background technique [0002] Graphite materials are widely used in energy, environmental protection, information, transportation, national defense and other new technology fields, which put forward higher requirements for the purity of graphite materials. At present, graphite purification is carried out through the reaction of graphite and process gas. For example, chlorine gas is used as the process gas, and the chemical reaction between chlorine gas and high-boiling-point metal impurities in the material occurs at a set temperature to generate low-boiling-point chlorides, so that impurities are eliminated. Gasified and discharged to achieve the purpose of graphite purificat...
