Abstract

L'invention concerne une installation pour l'aspiration d'air chargé de substances nocives. L'installation comporte des hottes dont les papillons il sont pontés chacun par un conduit de courant d'essai 13 constamment ouvert, muni d'un instrument à fonctionnement continu 16 qui mesure avec un faible retard la teneur en substances nocives de l'air aspiré et qui est relié à l'entraînement de réglage final 12 du papillon Il correspondant. En un point d'aspiration constamment ouvert 10, est prévu un instrument de mesure de pression d'aspiration 19 pour un régulateur 20 qui influence le dispositif de réglage final 7 du ventilateur 4. Application au dépoussiérage secondaire de halles d'aciérie, etc.The invention relates to an installation for the suction of air loaded with harmful substances. The installation comprises hoods, the butterflies of which are each bridged by a constantly open test current conduit 13, fitted with a continuously operating instrument 16 which measures with a low delay the content of harmful substances in the air drawn in. and which is connected to the final adjustment drive 12 of the corresponding throttle II. At a constantly open suction point 10, there is provided a suction pressure measuring instrument 19 for a regulator 20 which influences the final adjustment device 7 of the fan 4. Application to the secondary dedusting of steelworks, etc.
