Take dry exhaust -gas treatment's of carbon black carbon black tail gas incineration boiler, including carbon black tail gas incineration boiler main part and flue gas emission pipe way, still includea dry waste gas branch road and flue gas, waste gas constant temperature mixing arrangement, the flue gas, one of them entry of waste gas constant temperature mixing arrangement passes through the pipe connection with the exhanst gas outlet of carbon black tail gas incineration boiler main part, another entry is connected with the exhaust outlet of dry waste gas branch road, the flue gas, the entry linkage on SCR denitrification facility and flue gas emission pipe way is passed through in waste gas constant temperature mixing arrangement's export. This take dry exhaust -gas treatment's of carbon black carbon black tail gas incineration boiler reasonable in design, investment and running cost synthesize and reduce carbon black production exhaust emission environmental protection pressure with low, have carried forward vigorously the processing technique and the energy saving and emission reduction technology's of carbon black waste gas synchronous development.
