| 摘要 |
The present invention relates to a fluidized bed reactor and, more specifically to a discharging pipe for the fluidized bed reactor which can reduce a size deviation of produced silicon particles by returning small sized silicon particles which are not fully grown to the inside of the fluidized bed reactor through a gas injection into the silicon particles being discharged through a discharging hole. The discharging pipe discharging grown silicon particles by being connected to the fluidized bed reactor comprises: a main body which is a hollow type having a fixed height and whose one end is connected to the discharging hole of the fluidized bed reactor; a hollow type gas accommodating pipe in which a fixed amount of gas supplied by a gas supply source by being arranged to surround the outer circumference of the main body; and at least one connection pipe transferring the gas from the gas accommodating pipe to the inside of the main body by connecting the gas accommodating pipe to the main body, wherein the size of the silicon particles being discharged outward with buoyancy generated by the gas being discharged from the connection pipe is limited. |
