Zusammenfassung:The invention relates to a system (1) and a method for collecting and handling dust in a paper-making environment. The system (1) comprises a source of underpressure (2) and an elongated collector (4) that extends along a longitudinal axis and which elongated collector (4) is connected to the source of underpressure (2) through at least one suction duct (7) such that underpressure can be generated inside the elongated collector (4). The elongated collector (4) has an inlet (5) through which dust-laden air can enter the elongated collector (4) and an exit opening (6) leading to the suction duct (7) through which exit opening (6) dust-laden air can be evacuated from the elongated collector (4). A source of water (8) is connected by at least one water supply duct (10) to the elongated collector (4) such that water from the source of water (8) can be introduced into the elongated collector so that dust in the dust-laden air can be exposed to and mix with the water introduced into the elongated collector (4). A flow meter (12) is functionally connected to the system (1) to measure at least one of a flow of water from the source of water (8) to the elongated collector (4) or a flow of water exiting from the elongated collector (4) through the exit opening (6) of the elongated collector (4) and arranged to send a signal indicating a numerical value for a flow of water that reaches or leaves the elongated collector (4) such that this value can be compared to a predetermined minimum value. The system is used to carry out the inventive method. L'invention concerne un système (1) et un procédé de collecte et de manipulation de poussière dans un environnement de fabrication de papier. Le système (1) comprend une source de dépression (2) et un collecteur allongé (4) qui s'étend le long d'un axe longitudinal, le collecteur allongé (4) étant relié à la source de dépression (2) par l'intermédiaire d'au moins un conduit d'aspiration (7) de sorte qu'une dépression puisse être générée à l'intérieur du collecteur allongé (4). Le collecteur allongé (4) a une entrée (5) à travers laquelle de l'air chargé de poussière peut entrer dans ledit collecteur allongé (4) et une ouverture de sortie (6) menant au conduit d'aspiration (7), l'air chargé de poussière pouvant être évacué du collecteur allongé (4) à travers ladite ouverture de sortie (6). Une source d'eau (8) est reliée par au moins un conduit d'alimentation en eau (10) au collecteur allongé (4) de sorte que l'eau provenant de
