摘要： 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.
摘要翻译：本发明涉及一种用于在造纸环境中收集和处理粉尘的粉尘处理装置（1），其中粉尘处理装置（1）包括负压源（2）和细长收集器（3），其沿着纵向轴线延伸。细长收集器（3）连接到负压源（2），使得可以在细长收集器（3）内产生负压，并且细长收集器（3）具有入口（5），含尘空气可以通过入口细长收集器（3）和出口开口（6），含尘空气可通过该出口从细长收集器排出。细长收集器（3）的入口（5）相对于细长收集器（3）的纵向轴线设置成使得在将含有灰尘的空气吸入细长收集器（3）时，空气涡流是（5）和收集器出口（6）之间流动的引入的空气涡流引入含尘空气中。水源（7）连接到细长收集器，使得水能够被引入到细长收集器（3）中，使得含尘空气的灰尘可以暴露于并且与引入到细长收集器（3）中的水混合）。根据本发明，除尘装置（8,10）安装在细长收集器上，并设置成抵靠入口（5）以除去堵塞入口（5）的灰尘。本发明还涉及去除堵塞入口（5）的灰尘。

摘要： The invention relates to a Yankee drying hood arrangement (1) which is shaped to be fitted over a Yankee drying cylinder (2) such that the drying hood arrangement (1) can cover a part (4) of the circular cylindrical surface (3) of a Yankee drying cylinder (2). The Yankee drying hood arrangement (1) comprises a plurality of nozzle boxes (5) distributed equidistantly around an imaginary axis (X) such that, when the Yankee drying hood arrangement (1) is fitted over a Yankee drying cylinder (2), the nozzle boxes (5) are spaced from the circular cylindrical surface (3) of the Yankee drying cylinder (2) but form a curved structure (6) that follows the outer contour of the circular cylindrical surface (3) of the Yankee drying cylinder (2). Each nozzle box (5) has a longitudinal extension in a direction parallel to the axial extension of the Yankee drying cylinder (2) and each nozzle box (5) has openings (7) distributed along the longitudinal extension of the nozzle box (5) through which openings (7) a fluid such as hot air can exit the nozzle boxes (5) and stream towards the circular cylindrical surface (3) of the Yankee drying cylinder (2) at different points at different points along the axial extension of the Yankee drying cylinder (2). The Yankee drying arrangement further comprises a plurality of distributor conduits (8) for a fluid such as hot air and the distributor conduits (8) extend in the circumferential direction around the curved structure (6) formed by the nozzle boxes (5). Each distributor conduit (8) is in communication with several nozzle boxes (5) such that a fluid such as hot air can stream from each distributor conduit (8) to several different nozzle boxes (5). At least one main supply conduit (9, 10) for a fluid such as hot air is in communication with the distributor conduits (8) such that a fluid such as hot air can stream to the distributor conduits (8). The distributor conduits (8) are oriented around the curved structure (6) of the nozzle boxes (5) in such a pattern that, when one and the same distributor conduit (8) communicates with different nozzle boxes (5), it does so at different points along the longitudinal extension of the different nozzle boxes (5). The invention also relates to a Yankee drying cylinder fitted with the inventive Yankee drying hood arrangement and to a method of drying a fibrous web.
