Device and process for recycling dyeing liquid of acid dye for fur

The invention discloses a device and a process for recycling dyeing liquid of acid dye for fur. The device comprises a dyeing filter mechanism, a water storage pond, a water collecting cylinder and a decoloring and sterilizing air-floatation treatment device. The fur is dyed and treated at three stages, and the dyeing liquid is independently collected at each stage and can be recycled. The device and the process have the advantages that the dyeing liquid can be independently collected after the fur is dyed by means of water bath, and can be recycled after being treated in workshops, accordingly, the chemical material cost can be saved by 30% as compared with the traditional method, the sewage treatment cost can be saved by 70% as compared with the traditional method, the production cost and the water treatment cost can be reduced, influence on environments can be decreased, and the problem of difficulty in environmental protection and energy conservation in the fur dyeing and finishing industry can be solved.
