NOVELTY - The method involves connecting the upper and lower inflection points of the two broken-line support portions by the cylindrical rods. The cylindrical rods are parallel to each other and perpendicular to the support portions. The upper and lower rods (3,4) are connected to the upper and lower inflection points. The single-layer thermal fabric is tightly tightened on the support frame and is in close contact with the upper surface of the upper cylindrical rod, and is in close contact with the lower surface of the lower cylindrical rod. The plane formed by all the lower cylindrical rods of the support frame is immersed in the seawater parallel to the seawater surface, and the immersion depth is 1/8 of the vertical height between the upper cylindrical rod and the lower cylindrical rod. The photothermal fabric is a fabric woven from carbon fibers or a fabric deposited with graphene or carbon nanotubes. The fabric is a woven fabric, knitted fabric or non-woven fabric. USE - Method for generating solar steam. ADVANTAGE - All areas of the entire fabric surface is prevented from appearing during the evaporation process. The solution is saturated and salt is precipitated. The situation that the photothermal efficiency is reduced due to the precipitation of solid salt is effectively avoided. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the process for generating solar steam. Folding linear support portion (2) Upper rod (3) Lower rod (4)
