Treatment device and treatment method for double wastes in carbon fiber production

The invention provides a treatment device and a treatment method for double wastes in carbon fiber production, and relates to the technical field of carbon fiber production environmental protection. Specifically, the treatment device mainly comprises a reaction device, a lye tank, an exhaust device, a multi-effect evaporator and a crystallizer which are communicated in sequence, the reaction device is used for bearing the waste sizing liquid produced by the carbon fibers; and the exhaust device is used for exhausting waste gas generated in the carbon fiber production process. When the treatment device and the treatment method are used for treating the waste sizing agent and the waste gas in the carbon fiber production process, the technical problems that in the prior art, greenness and environmental protection cannot be considered at the same time, and the treatment cost is too high can be solved; rapid degradation and demulsification of the waste sizing agent are achieved, the treatment efficiency of the was
