Recycling system for chemical recycling method of waste PET materials

The present invention provides a recycling system for chemical recycling method of waste PET (polyethylene terephthalate) materials. An outlet of a degradation and filtration system is connected to an inlet of a degradation liquid cooling crystallization system through a pipeline; an outlet of the degradation liquid cooling crystallization system is connected to an inlet of an ethylene glycol and BHET separation circulatory system through a pipeline; an outlet of the ethylene glycol and BHET separation circulation system is connected to an inlet of a BHET quantitative feeding system through a pipeline; an outlet of the BHET quantitative feeding system is connected to an inlet of a hydrolysis and filtration system through a pipeline; the outlet of the hydrolysis and filtration system is connected to an inlet of an activated carbon filtration system through a pipeline; the outlet of the activated carbon filtration system is connected to an inlet of a hydrolysis liquid cooling crystallization system by a pipeline; an outlet of the hydrolysis liquid cooling crystallization system is connected with an inlet of the water and BHET separation circulatory system through a pipeline; and the outlet of the water and BHET separation circulatory system is connected to a BHET drying and packaging system through a pipeline. The system can effectively increase the cleanliness of the finished product, thereby improving the integral quality of the processed product.
