Plasma reactor for preparing carbon material by countercurrent cracking of gaseous hydrocarbon

The utility model discloses a plasma reactor for preparing a carbon material by countercurrent cracking of gaseous hydrocarbon. The plasma reactor is used for preparing carbon black by using equipmentconsisting of a cathode, an insulator, an anode, a reactor body, a raw material inlet pipe and ancillary facilities of the raw material inlet pipe. The plasma reaction system is provided with three paths of gas inlets, namely a raw material gas inlet, a carrier gas inlet and an auxiliary gas inlet, and each path of gas plays different roles in the reaction process, so that the temperature, atmosphere and retention time required by cracking of gaseous hydrocarbon raw materials can be accurately controlled, and the variety and quality of carbon black can be guaranteed. The torch route arrangement of a plasma generator arranged on the plasma reaction system is opposite to a gaseous hydrocarbon raw material injection route, a countercurrent trend is presented, gaseous hydrocarbon can be rapidly mixed with a high-temp
