Method and device for locating accumulations of pollutants

Abstract

A method for locating an accumulation of pollutants includes continuously guiding a conveying medium in mutually opposite directions through two legs of a pollutant-permeable collecting line, the legs being placed closely adjacent and mutually parallel as forward and return lines. A detection is performed as to whether or not the conveying medium contains a pollutant at an outlet of the collecting line. A location of an accumulation of pollutants at the collecting line is determined from a difference in time between two successive pollution detections at the outlet of the collecting line. A device for locating accumulations of pollutants includes a collecting line being permeable to a pollutant and having two legs being closely adjacent, mutually parallel and switched as forward and return lines. A continuously operating pump is connected to the collecting line for conveying a conveying medium through the collecting line. A sensor is connected to the collecting line for detecting a pollutant. An evaluation unit is connected to the sensor.
