Title
(EN) DEVICE FOR PROTECTING FUME INTAKE INTO A SCRUBBER, AS WELL AS CLEANING FACILITY COMPRISING SUCH A DEVICE
(FR) DISPOSITIF DE PROTECTION D'ENTRÉE DE FUMÉES DANS UN ÉPURATEUR, AINSI QU'UNE INSTALLATION DE NETTOYAGE COMPRENANT UN TEL DISPOSITIF
Abstract
(EN)
This protection device (10) is suitable for being arranged inside a scrubber and including an apical body (11) which, when the protection device is installed in the scrubber, is placed above the downstream mouth of a vertical duct for admitting fumes into the scrubber, so as to protect the duct against the introduction of water while allowing the fumes leaving the duct to pass. In order for this protection device to perform particularly well, an upper face (12) of the apical body is provided with water collection channels (14), which each extend lengthwise from a central region (11 A) of the apical body, around which the channels are distributed, to a periphery (11 B) of the apical body, which is completely occupied by the channels. Each channel has, over its entire length, a cross-section that is substantially triangular and whereof the lower apex defines a bottom edge (15) along the channel. The respective bottom edges of the channels rest on a conical surface that converges upwards and the apical angle of which is between 90 and 170°.
(FR)
Ce dispositif de protection (10) est approprié pour être disposé à l'intérieur d'un épurateur et comprend un corps apical (11) qui, lorsque le dispositif de protection est installé dans l'épurateur, est placé au-dessus de l'embouchure aval d'un conduit vertical d'admission des fumées dans l'épurateur, de manière à protéger le conduit contre l'introduction d'eau tout en laissant passer les fumées sortant du conduit. Afin que ce dispositif de protection fonctionne particulièrement bien, une face supérieure (12) du corps apical est pourvue de canaux de collecte d'eau (14) qui s'étendent chacun dans le sens de la longueur à partir d'une région centrale (11 A) du corps apical, autour duquel les canaux sont répartis, à une périphérie (11 B) du corps apical, qui est complètement occupée par les canaux. Chaque canal a sur toute sa longueur une section sensiblement triangulaire et dont le sommet inférieur définit un bord inférieur (15) le long du canal. Les bords inférieurs respectifs des canaux reposent sur une surface conique qui converge vers le haut et dont l'angle apical est compris entre 90 et 170°.
