▎ 摘　　要

NOVELTY - Solar photo-thermal evaporation steam collecting device comprises a transparent top cover (1) and a collecting device (2) connected with the transparent top cover in sealing manner and provided with an interface evaporation unit (3). The interface evaporation unit comprising a water storage tank (6) filled with seawater. The opening of the water storage tank is provided with a heat insulating plate (4) stacked with multiple fibre cloth, two sides of the fibre cloth drop into the sea water of the water storage tank, the portion of the fibre cloth located on the heat insulating plate is loaded with photo-thermal material, the side wall (10) of the collecting device is equipped with several air flow perturbators capable of blowing the steam generated by heating and evaporating the sea water to the inner wall of the collecting device to collect or extract and collect the steam. USE - Solar photo-thermal evaporation steam collecting device used in a seawater desalination system i.e. reverse osmosis membrane (RO) system. ADVANTAGE - The device has high evaporation efficiency, high condensing water collecting efficiency, high purity of collecting water quality, low cost and wide application characteristics. DESCRIPTION OF DRAWING(S) - The drawing shows an integral schematic view of a device. 1Transparent top cover 2Collecting device 3Interface evaporation unit 4Heat insulating plate 6Water storage tank 10Side wall
