Title (EN) DEVICE FOR COLLECTING AND DETECTING AEROSOLS
(FR) DISPOSITIF DE COLLECTE ET DE DETECTION D'AEROSOLS
Abstract:
(EN) The invention relates to a device (10, 11) for collecting and detecting aerosols, comprising a flow channel for the aerosol-containing air and an active portion (44) of an aerosol collection filter disposed across the flow channel and separating a gas supply line (40) from a gas discharge line. According to the invention, the air supply line includes a first air inlet (40a) and a second inlet (40b). In addition, the air supply line (40) is shaped such that at least one straight line can pass through the first air inlet and through the second air inlet while extending entirely inside the air supply line.
(FR) L'invention concerne un dispositif (10, 11) de collecte et de détection des aérosols comprenant un canal d'écoulement pour l'air chargé des aérosols, une partie active (44) d'un filtre de collecte des aérosols disposée en travers du canal d'écoulement et séparant un conduit d'amenée (40) du gaz d'un conduit d'évacuation du gaz. Selon l'invention, le conduit d'amenée d'air comprend une première entrée d'air (40a) et une seconde entrée (40b). Le conduit d'amenée d'air (40) est également conformé de manière à ce qu'au moins une droite puisse passer par la première entrée d'air et par la seconde entrée d'air tout en s'étendant intégralement à l'intérieur du conduit d'amenée d'air.
