SEAWATER INTAKE PIPE ASSEMBLY

PURPOSE: A seawater intake pipe assembly is provided to intake seawater with a uniform suction force and to prevent suction blockage of filtered seawater by making discharge pressure uniform when reverse-washing and securing a seawater inflow space. CONSTITUTION: A seawater intake pipe assembly(120) includes a water intake inner pipe(122), a water intake outer pipe(124) and a spacer ring(126). The water intake inner pipe includes a plurality of seawater intake holes(122a) and a plurality of leachate suction holes(122b). The water intake outer pipe is arranged to cover the external periphery of the water intake inner pipe. The spacer ring is arranged between the water intake inner pipe and the water intake outer pipe and forms a pressure control and seawater inflow space(v).
