Abstract
The invention relates to a system () and a method for collecting and handling dust in a paper-making environment. The system () comprises a source of underpressure () and an elongated collector () that extends along a longitudinal axis and which elongated collector () is connected to the source of underpressure () through at least one suction duct () such that underpressure can be generated inside the elongated collector (). The elongated collector () has an inlet () through which dust-laden air can enter the elongated collector () and an exit opening () leading to the suction duct () through which exit opening () dust-laden air can be evacuated from the elongated collector (). A source of water () is connected by at least one water supply duct () to the elongated collector () such that water from the source of water () 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 (). A flow meter () is functionally connected to the system () to measure at least one of a flow of water from the source of water () to the elongated collector () or a flow of water exiting from the elongated collector () through the exit opening () of the elongated collector () and arranged to send a signal indicating a numerical value for a flow of water that reaches or leaves the elongated collector () such that this value can be compared to a predetermined minimum value. The system is used to carry out the inventive method.
