Device for continuously producing hydrogen from polyester plastics by photocatalytic degradation

A device for continuously producing hydrogen from polyester plastics by photocatalytic degradation, comprising:

• a machine housing;
• a feeding mechanism provided at one side of the machine housing, wherein a bottom of the feeding mechanism is in communication with a dissolving mechanism for transporting waste plastics to the dissolving mechanism;
• the dissolving mechanism provided inside the machine housing, wherein the dissolving mechanism is configured for hydrolyzing the waste plastics into a solution containing small molecule monomers by means of a dissolving solution, and the dissolving mechanism transports the solution containing the small molecular monomers to a photocatalytic reactor through a solution circulation pipeline;
• the solution circulation pipeline arranged at another side of the machine housing, wherein two ends of the solution circulation pipeline are respectively connected to the dissolving mechanism and the photocatalytic reactor;
• and
• the photocatalytic reactor arranged above the dissolving mechanism, wherein the photocatalytic reactor is configured for degrading plastics in the solution containing the small molecular monomers to obtain a reaction solution and hydrogen.
