摘要： A drying system and method for removing volatile liquid from a liquid bearing web of material by evaporation includes means for moving the liquid bearing web (10) of material through a drying station (12) and heating means (14) position at the drying station, for applying evaporation energy to the liquid bearing web (10) of material to effect evaporation of the volatile liquid from the web. Electrostatic means (30) is provided for subjecting the web of material to a static electrical field at the drying station (12), whereby the evaporation of volatile liquid from the web is enhanced. Evaporation energy may be applied to the liquid bearing web (10) by bringing a heated surface (14) in contact with the web or by irradiating the web with infrared energy. Alternatively, evaporation energy may be applied to the liquid bearing web (10) by directing heated air against the web.

摘要： It is a known phenomenon that the web during the drying moment in a paper machine shrinks. The shrinkage in the machine direction can be controlled by arranging the different driving groups in the drying section to operate at different speeds. The shrinkage in cross direction, however, heretofore was not brought under control. The present invention has the object to solve thos problem. According to the invention, the problem of shrinkage is solved in that the web during a certain drying interval is subjected to outward directed forces, which are applied during a suitable drying interval and preferably at a low dry content, for example directly after the press section.

摘要： A seal arrangement in a fibre web drying apparatus, in which a fibre web (5) is dried between two tight bands (1, 2) that move in the same direction around turning rolls (6a, 6b, 7a, 7b). The first band (1) is heated by a pressure chamber (9), and the second band (2) is cooled by a water chamber (10). The fibre web (5), with at least one wire (3, 4), is led through a drying zone formed by the bands (1, 2) so that the fibre web is in contact with the surface of the first band (1), and the wire (3, 4) is between the fibre web (5) and the second band (2). The drying apparatus comprises side chambers (11) in which pressure medium dripping from the chambers (9, 10) collects. The ends of the side chambers (11) are sealed with an end seal (13), which comprises elongated sealing elements (15) attached at at least their one end and having a length that is greater than the height of the area to be sealed.

摘要： A steam box or hood (10) for controlling the moisture profile of a fibrous web such as paper during forming and pressing. The steam hood (10) includes a plenum (12) filled with nonturbulent, substantially atmospheric pressure steam which delivers the steam into a series of side-by-side compartments (17) which extend across the width of and adjacent to the web. Each compartment includes a damper (20), the position of which is individually controllable through a rod (22) adjustment from the operating side of the machine. The position of the damper (20) determines the amount of steam applied to the web from a compartment and hence the moisture content of the web adjacent to the particular compartment (17) being adjusted. Each compartment (17) is adjusted to achieve a desired uniform moisture content across the width of the web.

摘要： The invention relates to a method of and an apparatus for drying a fiber web, whereby the fiber web (5) is dried in a cylinder drying unit (12) and in a band drier unit (11). The cylinder drying unit (12) and the band drier unit (11) are arranged one above the other. A considerable space saving is then achieved and the building costs remain rather moderate. Simultaneously, a remarkable addition to the drying capacity is achievable by moderate investments by means of existing apparatuses, for instance.

摘要： Arrangement and method for controlling or regulating shrinkage and/or stretching of a paper web transversely to the transport direction thereof in a drying section of a paper machine, this drying section having the form of a cylinder dryer (6) and/or a fan dryer. At a point in the drying process at which the paper web exhibits a dry solids content of at most 75% the paper web (10) is subjected to an outwardly directed force which is forced to act in the edge portion (10a, 10b) of the web. The forces are caused to act adjacent parallel edge portions (10a, 10b) of the paper web and are directed away from each other. The magnitude of these forces is selected so that they fall beneath shrinkage forces occurring momentary on the paper web at the dry solids content in question by at most 50%.

摘要： A procedure for boosting the ventilation in drying sections of paper machines provided with a closed hood (1). In the procedure, air is blown on such surfaces which are susceptible to condensate precipitation. Air jets (F1, F2) are blown mainly obliquely downward through air ducts (11A, 11B) disposed adjacent to both side walls (7A, 7B) of the hood (1), above all towards the inner surfaces of the door, hatch and/or window structures (12A, 12B, 16, 17) in association with the lower part of the walls (7A, 7B) of the hood (1). The blowing air is taken to the air ducts (11A, 11B) from the air within the hood (1) or as a mixture of air within the hood (1) and of dry replacement air. For air ducts (11A, 11B) are used horizontal air ducts (11A, 11B) extending the length of the hood (1) and on which have been disposed blowing nozzles (8A, 8B), of which the blowing direction is obliquely towards the inner surfaces of doors (12A, 12B) or equivalent of the hood (1) adjacent to them or below them.

摘要： An apparatus for drying and smoothing a fibre web (5) between two tight bands (1, 2) that move in parallel and turn around turning rolls (6a, 6b, 7a, 7b), the first band (1) being heated with hot steam and the second band (2) being cooled with water, and the fibre web (5) being conducted through the drying zone that the bands (1, 2) define together with at least one felt or wire (3, 4) such that the fibre web (5) is in contact with the surface of the first, heated band (1) and that the felt or wire (3, 4) is between the fibre web (5) and the second, cooled band (2). In the invention, the fibre web (5) is smoothed such that the press means located in the vicinity of the first turning rolls (6a, 7a) in the travel direction of the fibre web (5) apply to it a pressure that is essentially higher than the pressure in the other parts of te drying zone. The pressure that the fibre web is subjected to in the drying zone is sufficiently high to prevent the fibre web from shrinking in the longitudinal and transverse directions, and yet sufficiently low to prevent the fibre web from becoming essentially thinner.
