The reactor comprises a reaction chamber, wherein the lower end of the reaction chamber is connected with a pipeline for outputting pyrolysis gas and carbon black water. The reaction chamber is characterized in that the reactor is internally provided with quenching nozzles connected through a quenching connecting pipe which extends out of the reaction chamber. The quenching connecting pipe is hermetically connected with the reactor. The height of the quenching nozzles in the reaction chamber can be adjusted by moving the quenching connecting pipe up and down. A nonmetal material layer is arranged on the inner wall of the reaction chamber. According to the reactor provided by the utility model, the optimal height for the maximum acetylene yield is obtained by adjusting the height of the quenching nozzles. A water jacket is replaced by a nonmetal material and an insulating material on the upper part of the reaction chamber, so that the temperature gradient is reduced, and negative effect to partial oxidation reaction of hydrocarbon by cold water effect is reduced.
