Apparatus and method for gas flow carbonization of energetic materials

Abstract

An apparatus for gas flow carbonization of energetic materials, including a screw conveyor and a heater. The screw conveyor includes an outer cylinder and a screw shaft. The outer cylinder is provided with a feeding port, a discharge port, a gas inlet and a gas outlet. The gas inlet and the gas outlet are each provided with a valve. The heater is configured to heat and supply inert gas to the gas inlet. A gas-flow carbonization method is also provided. After heating the inert gas to a required temperature, the discharge port is closed and the feeding port is opened. The heated inert gas is transported into the outer cylinder to maintain an oxygen volume concentration below 2%. After the to-be-treated material is inputted into the outer cylinder, the valve of the feeding port is closed.
