Disclosed is equipment for manufacturing furfural from corncobs. The equipment comprises an acid mixer and a plurality of reaction towers. The reaction towers and the acid mixer are connected through pipelines. Each reaction tower is connected with a heat exchanger. According to the equipment for manufacturing furfural from corncobs, the heat exchangers are arranged at the bottoms of the reaction towers, heat losses in the reaction towers are compensated for, condensation of water vapor inside the reaction towers is avoided, side reactions caused by liquid accumulation are reduced, and the xylose conversion rate is increased; meanwhile, the multi-stage reaction towers are arranged, so that gas phase furfural generated inside all the reaction towers is added, and therefore the furfural yield can be increased.
