The invention discloses a carbon black tail gas incineration boiler with a carbon black dry waste gas treatment function. The carbon black tail gas incineration boiler comprises a carbon black tail gas incineration boiler body and a smoke exhaust pipeline and further comprises a dry waste gas branch way and a smoke and waste gas constant-temperature mixing device. One inlet of the smoke and wastegas constant-temperature mixing device is connected with a smoke outlet of the carbon black tail gas incineration boiler body through a pipeline, and the other inlet of the smoke and waste gas constant-temperature mixing device is connected with a waste gas outlet of the dry waste gas branch way. An outlet of the smoke and waste gas constant-temperature mixing device is connected with an inlet ofthe smoke exhaust pipeline. The carbon black tail gas incineration boiler with the carbon black dry waste gas treatment function is reasonable in design, low in investment and running cost and capableof comprehensively reducing the carbon black production waste gas exhaust environment protection pressure and greatly promoting synchronous development of the treatment technology and the energy-saving and emission-reducing technology of carbon black waste gas.
