Title
(EN) DEVICE FOR CONTINUOUSLY SAMPLING AND ANALYSING A LIQUID EFFLUENT
(FR) DISPOSITIF POUR LE PRELEVEMENT EN CONTINU ET L'ANALYSE D'UN EFFLUENT LIQUIDE
Abstract
(EN)
A device for continuously sampling and analysing a liquid effluent, e.g. from an industrial plant. A device enabling rapid detection of pollutants in waste is provided. The device comprises a unit (6) for constantly diverting a portion of the liquid effluent to be analysed towards a first distribution unit (12), at least two temporary storage vessels (10) connected to the inlet of a sampling cell (22), and a unit (28) for removing a sample from said sampling cell (22) and feeding it to at least one measuring apparatus (30). Said first distribution unit (12) is designed to fill the empty temporary storage vessels (10) one after the other, which vessels (10) are then emptied into the empty sampling cell (22) in the order in which they were filled.

L'invention concerne un dispositif conçu pour effectuer le prélèvement en continu et l'analyse d'un effluent liquide, issu, par exemple, d'une installation industrielle. Le but de l'invention est de réaliser un dispositif permettant de déceler rapidement une pollution dans un rejet. Ce but est atteint à l'aide d'un dispositif comprenant: des moyens (6) pour détourner en permanence une partie de l'effluent liquide à analyser en direction de premiers moyens de distribution (12); au moins deux récipients de stockage provisoire (10), reliés à l'entrée d'une cellule de prélèvement (22); des moyens (28) pour prélever un échantillon dans ladite cellule de prélèvement (22) et le diriger vers au moins un appareil de mesure (30), lesdits premiers moyens de distribution (12) étant conçus pour remplir successivement un récipient de stockage provisoire (10) vide, ces récipients (10) étant vidés dans l'ordre où ils ont été remplis, dans ladite cellule de prélèvement (22) lorsque celle-ci est vide.
