Abstract
(EN)
Provided are a scrubber, an exhaust gas treatment device, and a ship, wherein a scrubber main body (33) which has a hollow shape, a venturi part (34) into which an exhaust gas is introduced, a first water injection part (36) which injects water towards the exhaust gas introduced into the venturi part (34) to remove harmful substances included in the exhaust gas, and a second water injection part (38) which injects water towards the wall surface of the venturi part (34) to remove adhered harmful substances are provided. As a result, adhesion of the harmful substances to the venturi part is inhibited.
(FR)
La présente invention concerne un épurateur, un dispositif de traitement de gaz d'échappement, et un navire, dans lesquels un corps principal d'épurateur (33) qui a une forme creuse, une partie venturi (34) dans laquelle un gaz d'échappement est introduit, une première partie d'injection d'eau (36) qui injecte de l'eau vers le gaz d'échappement introduit dans la partie venturi (34) pour éliminer les substances nocives contenues dans le gaz d'échappement, et une deuxième partie d'injection d'eau (38) qui injecte de l'eau vers la surface de paroi de la partie venturi (34) pour éliminer les substances nocives adhérant à celle-ci. En conséquence, l'adhésion des substances nocives est inhibée.
