Title
(EN) AIR TREATMENT DEVICE
(FR) DISPOSITIF DE TRAITEMENT D'AIR
Abstract
(EN) The present invention relates to an air treatment device (1 ) for treatment of air onboard a ship. The air treatment device (1) comprises an air exchange device (2), an exhaust air conduit (3) with an inlet part (6) and an outlet part (7), and with a first air flow direction (8) from the inlet part to the outlet part, a supply air conduit (4) with an inlet part (9) and an outlet part (10), and with a second air flow direction (11 ) from the inlet part to the outlet part, wherein the first air flow direction is opposite the second air flow direction. The air treatment device (1) comprises an enthalpy exchanger (5) comprising a plurality of ducts and arranged between the inlet part and the outlet part of the exhaust air conduit and between the inlet part and the outlet part of the supply air conduit. The enthalpy exchanger is rotatably supported by a rotation shaft. The air exchange device (2) is limited in height, comprises a purification device and is arranged for partial purification of exhaust air. The air exchange device (2) is arranged in connection to the enthalpy exchanger (5) between the rotation shaft of the enthalpy exchanger (5) and a distance above it in the air exhaust air conduit across the inlet part (6) of the exhaust air conduit.
(FR) La présente invention concerne un dispositif de traitement d'air (1) pour le traitement de l'air à bord d'un navire. Le dispositif de traitement d'air (1) comprend un dispositif d'échange d'air (2), un conduit d'air d'échappement (3) doté d'une partie d'entrée (6) et une partie de sortie (7), et présentant un premier sens d'écoulement d'air (8) de la partie d'entrée à la partie de sortie, un conduit d'air d'alimentation (4) doté d'une partie d'entrée (9) et d'une partie de sortie (10), et présentant un second sens d'écoulement d'air (11) de la partie d'entrée à la partie de sortie, le premier sens d'écoulement d'air étant opposé au second sens d'écoulement d'air. Le dispositif de traitement d'air (1) comprend un échangeur enthalpique (5) comprenant une pluralité de conduits et disposé entre la partie d'entrée et la partie de sortie du conduit d'air d'échappement et entre la partie d'entrée et la partie de sortie du conduit d'air d'alimentation. L'échangeur enthalpique est supporté en rotation par un arbre de rotation. Le dispositif d'échange d'air (2) est limité en hauteur, comprend un dispositif de purification et est agencé pour la purification partielle de l'air d'échappement. Le dispositif d'échange d'air (2) est disposé en liaison avec l'échangeur enthalpique (5) entre l'arbre de rotation de l'échangeur enthalpique (5) et à une distance au-dessus de celui-ci dans le conduit d'air d'échappement d'air à travers la partie d'entrée (6) du conduit d'air d'échappement.
