Abstract
The utility model relates to a tail gas absorbing and treating device used in the production process of carbon fiber. The tail gas absorbing and treating device comprises a spray tower and further comprises a tail gas heat exchanger, a tail gas condensate storage tank, a liquid adsorbing storage tank and an activated carbon absorbing tower. After tail gas is cooled by the tail gas heat exchanger, dimethyl sulfoxide and acrylonitrile gas in the tail gas are separated and recycled through the liquid adsorbing storage tank, the spray tower and the activated carbon absorbing tower, and finally a trace amount of residual gas is conveyed to an incinerator for incineration disposal. The tail gas absorbing and treating device can effectively absorb and treat gas produced during raw material purification and polymerization reactions in the production process of the carbon fiber, and can efficiently recycle dimethyl sulfoxide and the acrylonitrile gas in the tail gas. Therefore, while the environment is protected, the production cost of the carbon fiber is lowered.
