The present invention relates to a plasma ballast water treatment apparatus for a vessel provided with a module-type assembly, the plasma ballast water treatment apparatus being characterized by comprising: a housing provided with a first port and a second port and open at both ends; a plasma generation unit including a first electrode, which has both ends located at the center of the first port and the second port, respectively, a second electrode, which is formed along the inner circumferential surface of the housing, and a dielectric, which is formed between the first electrode and the second electrode and induces uniform plasma discharge between the first electrode and the second electrode; and a treatment means that includes a gas injection part for injecting a reaction gas from the outer circumferential surface on the first port side of the housing toward the inner space of the housing and a plasma discharge part communicating with the inner space of the housing along the outer circumferential surface of the housing and discharging, to the outside of the housing, plasma flame that has reacted with the reaction gas between the first electrode and the second electrode. The plasma ballast water treatment apparatus is a module type and makes it possible to treat ballast water of various capacities in both small and medium-sized vessels.

Abrégé

An embodiment of the present invention provides a swirl vane-type moisture separator, which is provided in a reactor steam generator, separates moisture from wet steam, and supplies dry steam to a turbine side, the swirl vane-type moisture separator comprising a riser and a swirl vane. The riser includes: an inner tube which has a steam flow path formed therein, through which wet steam flows from a lower portion and dry steam is discharged to an upper portion, and a liquid film passage hole which is formed on the circumference of the upper end and through which a liquid film formed by droplets separated from the wet steam passes; and an outer tube that is provided so as to surround at least the upper circumference of the inner tube and forms a downcomer through which the liquid film that has passed through the liquid film passage hole flows down and is discharged. The swirl vane is rotatably provided at a predetermined position in the steam flow path, and separates the droplets by means of centrifugal force from the wet steam moving along the steam flow path.
