The application discloses a preparation method of a 3D-printed biomimetic self-suspending solar evaporator. The application takes acrylonitrile-butadiene-styrene copolymer (ABS) and thermoplastic polyurethane elastomer (TPU) as raw materials, and prepares ABS-TPU wires through a double-screw extruder and a single-screw extruder. Photothermal materials, carbon black (CB) or carbon nanotube (CNT), can be added to the ABS-TPU wires through blending. A multi-channel biomimetic self-suspending ACy and ACy / CB (CNT) solar evaporator is constructed by using a 3D printing technology. General immersion treatment is combined with spraying technology to coat and load polydopamine (PDA) and a photocatalyst on the 3D-printed biomimetic self-suspending solar evaporator, thereby obtaining a biomimetic self-suspending solar evaporator (ACy / PDA / photocatalyst or ACy / CB (CNT) / PDA / photocatalyst) solar evaporator which is excellent in hydrophilic performance, photothermal conversion performance and photocatalytic performance, and which can realize water purification while evaporating water.

The utility model relates to oxidation equipment technical field, the utility model provides a double -effect catalytic oxidation device, it includes the material pipeline, injects the pipe for injecting the reagent to the material pipeline, mixes the axle one end rotation setting on the lateral wall of material pipeline, can mix reagent and water through rotation, the box has the processing cavity with the material pipeline intercommunication, the board piece sets up on the lateral wall of box, and the board piece surface has titanium dioxide coating, the sleeve sets up on the lateral wall of box, the ultraviolet lamp tube sets up in the pipe cavity, is used for the illumination titanium dioxide coating on the board piece surface and mixed reagent and water. The titanium dioxide coating on the board piece surface is excited to produce electron -hole pair under the ultraviolet lamp tube illumination, and electron is captured to generate super oxygen free radical by O2, and the hole can directly oxidize organic matter or react with water to generate hydroxyl radical, simultaneously, titanium dioxide can also be used as catalyst to realize the efficient activation of H2O2, and continuously generate free radical. The problem that traditional catalyst is easy to pollute, deactivation has been solved.
