A composite hydrogel sponge and its preparation method and application, and a solar desalination device are provided. The composite hydrogel sponge includes a water supply layer and an evaporation layer disposed on the water supply layer. A material of the water supply layer is polyacrylamide hydrogel, and a material of the evaporation layer is polyacrylamide/graphene composite hydrogel. The polyacrylamide/graphene composite hydrogel includes the polyacrylamide hydrogel and the graphene dispersed in the polyacrylamide hydrogel. The composite hydrogel sponge has a special porous structure of the sponge, which is beneficial to the rapid transmission and supply of water; meanwhile, the graphene on the surface of the evaporation layer can fully receive solar energy to achieve higher photo-thermal conversion efficiency.
