▎ 摘　　要

NOVELTY - The device has a water injection cavity (10) whose lower portion is provided with a water collecting chamber (11). A conical filter (12) is provided on the cavity. A pressure pipe (14) is connected with the collecting chamber. A filtering ball cavity (15) is formed by the wall filter (18). A conical graphene sieve (23) is provided on the filtering ball cavity provided with salt water cavity (17). The salt water cavity (24) is connected with a brine tank (21). The aperture size of the graphene sieve unit is equal to the diameter of the conical screen vertical column. USE - Graphene sieve desalting unit for steamship. ADVANTAGE - The manufacturing process of the graphene sieve desalting device is simplified. The operability of the device is strong. The cost of the device is low. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene sieve desalting unit.
