FOAM RECOVERY APPARATUS AND FOAM RECOVERY SYSTEM

摘要

This invention provides a foam recovery apparatus constructed so that foams, which float on the surface of a used sea water after desulfurization, are recovered and only the used sea water, from which foams have been removed, can be discharged into a surrounding ocean area. The foam recovery apparatus is a foam recovery apparatus (20), which is installed within a water passage (1) through which a used sea water discharged from a desulfurization column in an exhaust gas desulfurizer using sea water as an absorbing agent is allowed to flow and is discharged to remove and recover foams (4) floated on the surface of the used sea water. A foam gathering float body (50) is provided which is connected to a foam recovery pit part (40) through an overflow weir (30) provided on the side face of the water passage (1) and is held in a floated state so as to go across the water passage (1), whereby foams (4) floated on a water surface (WL) and a surface sea water stream are separated from a main stream of the used sea water and are led to the foam recovery pit part (40).
