Title:
EXHAUST COOLING DEVICE, DEVICE FOR PRODUCING FULLERENE AND METHOD FOR PRODUCING FULLERENE
Document Type and Number:
Japanese Patent JP2021107311
Kind Code:
A
Abstract:
To provide an exhaust cooling device that can improve the yield of fullerene, and a method for producing fullerene.SOLUTION: A cooling device 31 cools exhaust discharged from a reactor 11 used for production of fullerene by a combustion method. The cooling device 31 has a cooling device main body 34, and inert gas inflow means that allows inflow of inert gas. The cooling device main body 34 has an exhaust inflow port 32, an exhaust outflow port 33, and a side wall 37 provided between the exhaust inflow port 32 and the exhaust outflow port 33. The side wall 37 is provided with an inert gas inflow port 36. The inert gas inflow means flows inert gas from the inert gas inflow port 36 toward the center of flow of the exhaust discharged from the reactor 11.SELECTED DRAWING: Figure 1
