Abstract

The invention relates to a dust-handling device (1) for collecting and handling dust in a paper-making environment wherein the dust-handling device (1) comprises a source of underpressure (2) and an elongated collector (3) that extends along a longitudinal axis. The elongated collector (3) is connected to the source of underpressure (2) such that underpressure can be generated inside the elongated collector (3) and the elongated collector (3) has an inlet (5) through which dust-laden air can enter the elongated collector (3) and an exit opening (6) through which dust-laden air can be evacuated from the elongated collector. The inlet (5) of the elongated collector (3) is disposed in such a relation to the longitudinal axis of the elongated collector (3) so that upon drawing the dust-laden air into the elongated collector (3), an air vortex is induced with the dust-laden air wherein the induced air vortex flows between the collector inlet (5) and the collector exit opening (6). A source of water (7) is connected to the elongated collector such that water can be introduced into elongated collector (3) so that dust of the dust-laden air can be exposed to and mix with the water introduced into the elongated collector (3). According to the invention, a dust removal device (8, 10) is mounted on the elongated collector and arranged to act against the inlet (5) to remove dust that has clogged the inlet (5). The invention also relates to a method in which dust clogging the inlet (5) is removed.
