The invention provides an acetylene generator, and relates to the field of acetylene generation equipment. The acetylene generator comprises a generator cylinder body and is mainly composed of the generator cylinder, a connecting rack, a stirring driving device, a driving shaft, a first material guide disc, a second material guide disc, a third material guide disc, a fourth material guide disc anda fifth material guide disc, the first material guide disc, the second material guide disc, the third material guide disc, the fourth material guide disc and the fifth material guide disc are orderlyconnected to the generator cylinder body from top to bottom, the generator cylinder is vertically arranged, a sealing feeder is arranged on one side of the generator cylinder, a flaring feeding modeis adopted, and a nozzle device is arranged at the top of the generator cylinder and located above the first material guide disc. The acetylene generator has the advantages of being simple in structure, capable of achieving continuous feeding, small in water consumption, high in acetylene yield and the like, meanwhile, the six layers of guide arms are arranged, so that raw materials react sufficiently, and the utilization rate of the raw materials is high.
