Abstract
The invention provides a high-temperature gasification reaction pipe of a quartz sand purifying device. The high-temperature gasification reaction pipe is a horizontal reaction pipe. One end of the reaction pipe is provided with a shrinking gas inlet, the pipe wall of the reaction pipe, which is close to the gas inlet, is provided with at least one discharging hole, and the gas inlet is positioned in the center axial line of the reaction pipe. The other end of the reaction pipe is provided with a shrinking feeding hole, and the feeding hole is arranged in the center axial line of the reaction pipe. The horizontal reaction pipe is adopted without enabling the pipe body to reach an integrally filling state, thus the problem that the reaction pipe is broken due to phase change and volume expansion of quartz under a high temperature condition. The whole pipe body realizes that materials continuously overturn in a rotating process to ensure that the reaction is carried out more fully and the reaction efficiency is high as well as the problems of hardening, adhering and the like cannot be easily caused.
