A centrifugal separation type desalination system is provided to improve water treatment efficiency by primarily removing various alien substances contained in raw water, thereby preventing fouling from generating in a filtering membrane or a reverse osmosis membrane. In a desalination system for collecting raw water and filtering the raw water, a centrifugal separation type desalination system comprises: a pre-treatment part(10) for performing a pre-treatment process of filtering alien substances in the raw water collected from a drinking water source(21); and a fresh water treatment part(50) for treating the raw water that has been pre-treated in the pre-treatment part into fresh water by a reverse osmosis membrane module(53), wherein the pre-treatment part includes a centrifugal separation type filter(100) for generating a spiral flow in raw water supplied through a raw water line(37) to filter primarily alien substances from the raw water by a specific gravity difference, an automatic pressure type filter(31) for secondly filtering alien substances from the primarily filtered raw water by a filtering material, and a micro-filter(33) for thirdly filtering residual alien substances and microorganisms from the secondly filtered raw water by a filtering membrane, and wherein the centrifugal separation type filter includes a cylindrical body, an inflow pipe, a spiral guiding vane, a settling part, a sediment discharge pipe, a conical sediment flotation preventing partition, a blocking partition, a cylindrical filter mesh, a drain pipe, and a plurality of settling induction plates. |
