Title
(EN) BALLAST WATER TREATMENT SYSTEM BASED ON WHIRLING MOTION, HYDRODYNAMIC CAVITATION AND VACUUM EFFECT
(FR) SYSTÈME DE TRAITEMENT D'EAU DE BALLAST BASÉ SUR LE MOUVEMENT TOURBILLONNAIRE, LA CAVITATION HYDRODYNAMIQUE ET L'EFFET DE VIDE
Abstract
(EN)
The International Convention on Control and management of Ship's Ballast Water and Sediments stipulates conditions related to ballast water treatment systems which are high efficiency of the method at removing the targeted organisms, minimum damage to the environment, crew safety, economical and simple application. The invention relates to the ballast water treatment system based on whirling motion, hydrodynamic cavitation and vacuum effect. The system is embodied in the variants (I, II and III): Variant I - system with unit (U) for whirling, hydrodynamic cavitation and vacuum effect comprising cylindrical chamber (9), two vortex tubes (2) with a cylindrical nozzle (3) at the ends of each vortex tube; Variant II - system with unit (V) for whirling, hydrodynamic cavitation and vacuum effect comprising cylindrical chamber (9), two conical funnels (10), two vortex routers (14), two vortex tubes (2) and nozzle (11 ) with cavitation jet router (12) at the ends of each vortex tube; and Variant III - system with unit (Z) for whirling, hydrodynamic cavitation and vacuum effect comprising cylindrical chamber (9), two conical funnels (10), two vortex routers (14) and two vortex tubes (2) and nozzle (18) with several cavitation jet routers (12) in each vortex tube. In the units (U, V and Z) between vortex tubes and nozzles occur hydrodynamic cavitation and vacuum effect that destroy harmful marine organisms and disinfect sea water. The system working process does not include use of biocides or any other chemicals.

Selon l'invention, la convention internationale pour le contrôle et la gestion des eaux de ballast et sédiments des navires stipule des conditions se rapportant aux systèmes de traitement d'eau de ballast qui sont une efficacité élevée du procédé pour la suppression des organismes ciblés, un dommage minimal à l'environnement, la sécurité de l'équipage et une application économique et simple. L'invention se rapporte au système de traitement d'eau de ballast basé sur le mouvement tourbillonnaire, la cavitation hydrodynamique et l'effet de vide. Le système est réalisé dans les variantes (I, II et III) : variante I - un système comprenant une unité (U) pour le tourbillonnement, la cavitation hydrodynamique et l'effet de vide, comprenant une chambre cylindrique (9) et deux tubes vortex (2), une buse cylindrique (3) se trouvant aux extrémités de chaque tube vortex; variante II - un système comprenant une unité (V) pour le tourbillonnement, la cavitation hydrodynamique et l'effet de vide, comprenant une chambre cylindrique (9), deux entonnoirs coniques (10), deux répartiteurs à vortex (14), deux tubes vortex (2) et une buse (11), un répartiteur de jet de cavitation (12) se trouvant aux extrémités de chaque tube vortex; et variante III - un système comprenant une unité (Z) pour le tourbillonnement, la cavitation hydrodynamique et l'effet de vide, comprenant une chambre cylindrique (9), deux entonnoirs coniques (10), deux répartiteurs à vortex (14) et deux tubes vortex (2) et une buse (18), plusieurs répartiteurs (12) de jet de cavitation étant disposés dans chaque tube vortex. Dans les unités (U, V et Z), entre les tubes vortex et les buses il se produit une cavitation hydrodynamique et un effet de vide qui détruisent les organismes marins dangereux et désinfectent l'eau de mer. Le processus de fonctionnement du système ne comprend pas l'utilisation de biocides ou de quelconques autres produits chimiques.
