The carbonization waste gas in the carbon fiber production process was treated using a three zone direct combustion incinerator,and the effects of processes parameters such as reduction zone temperature,oxidation zone temperature,and furnace pressure on the treatment efficiency of hydrogen cyanide(HCN)were discussed.The results show that increasing the temperature of the reduction and oxidation zones and controlling the furnace pressure can help improve the HCN treatment efficiency,controlling a relatively low oxygen volume fraction can restrain the formation of NOx.After being treated by the three-zone direct burning incinerator,the mass concentration of HCN in carbonized waste gas is less than 1.9 mg/m3,meeting the requirements of the Comprehensive Emission Standard for Air Pollutants(DB 31/993-2015).
