Purification method for PAN-based carbon fiber production waste gas
PendingCN113813771AReduce concentrationGuaranteed uptimeDispersed particle filtrationIncinerator apparatusFiberParticulates
The invention discloses a purification method for PAN-based carbon fiber production waste gas. The method comprises the following steps: the PAN-based carbon fiber production waste gas is pretreated; the pretreated PAN-based carbon fiber production waste gas is introduced into a heat storage type thermal incineration system through a waste gas fan; the temperature of the waste gas is increased to 800 DEG C, so pollutants in the PAN-based carbon fiber production waste gas in the heat storage chamber are oxidized; and gas fully oxidized in the heat storage type thermal incineration system is induced by an induced draft fan and is exhausted through an exhaust funnel. According to the invention, a filter filled with a filtering material is used for filtering, so the concentration of particulate matters such as tar can be reduced, and normal operation of the heat storage type thermal incineration system is guaranteed; and the heat storage type thermal incineration system of a fixed three-chamber structure is utilized, main components in the waste gas are removed through thermal oxidation, generation of thermal nitric oxide is reduced, and a heat accumulator can recover heat generated by combustion to guarantee the temperature of the thermal oxidation chamber, thereby achieving energy-saving effect.
