Definitions
- the invention relates to a steam blower box for steaming a fibrous web, in particular a tissue web for the purpose of dry content increase and moisture cross profile ization in their manufacture, comprising a housing which is assigned at a distance and extending in the machine direction length of the fibrous web to be steamed and wherein the housing a Steam chamber encloses, which is provided with steam outlet openings and thus forms one of the steamed web to be vaporized steaming.
- Such a web treatment device in the range of calenders for smoothing the fibrous web is known from DE A1 102 55716 and in the region of a press for dewatering the fibrous web, for example from DE-A1 103 57 288.
- This contamination can sometimes be so severe that it must be cleaned between regular stoppages of the machine to avoid disturbances of operation by the steam box itself. If you were to swivel the steam box for cleaning purposes during operation, this would change the once set operating parameters and in turn lead to disturbances. These disturbances can be web breaks or poor moisture cross sections.
- the Bedampfungsumble is formed over a wide range or in zones.
- the existing openings can clog up or block. It comes thereby to the restriction or even to the failure of the function of the steam blow box.
- released fibers can be literally shot at the web by the steam jets from downstream steam vents, resulting in quality degradation of the manufactured web. It is therefore an object of the invention to provide such a steam blower box, in which the disadvantages of the prior art no longer occur.
- the steam outlet openings having steaming section is assigned to a arranged next to the steam chamber main steam chamber, wherein the Bedampfungsumble in the machine direction only about 10 to 50%, preferably 10 to 30% of the also extending in the machine direction total length of the housing and only at one Body of the housing is concentrated.
- the advantage of the solution according to the invention is that the steam delivered by the steam blower box is concentrated only for a short distance in the machine direction. As a result, released fibers from the fibrous web can not cause or only slight contamination.
- the Bedampfungs a Length in the machine direction, which is about 20 to 200mnn, preferably 20 to l OOmm and the length of the housing about 200 to 600mnn, preferably 200 to 400mnn. It is very expedient that the Bedampfungsumble is only at the end of the housing.
- tissue has a very open structure and that it does not even require a long steaming section or long effective path of the steam, as is customary in the prior art. It is therefore possible to make the production of tissue more effective by increasing the dry content of the web with the inventive short steaming section and concentration of the steaming section at only one point of the housing of the steam blow box and undertaking a moisture cross-profiling where the tissue web is passed over a pressure roller and pressed against a creping cylinder.
- a further advantageous embodiment of the steam blow box is that in the end region of the housing, the end of the Bedampfungsumble to the edge of the housing has a machine direction extending distance, which is about 20 to 200mm, preferably 50 to 150mm. This means that only the rear steam outlet openings are arranged at said distance.
- the steam outlet openings of the Bedampfungsumble are arranged in rows, with a plurality of rows is advantageous.
- one to six, preferably one to four rows may be provided.
- the individual outlet nozzles are preferably evenly spaced from one another.
- the steam outlet openings of the Bedampfungsumble each have the same diameter. Their size is about 3 to 6mm, preferably 3.5 to 4.5mm. These nozzles are acted upon in such a way that the speed at which the steam exits the steam outlet openings is about 10 to 60 m / s, preferably 10 to 40 m / s.
- a very effective heating and moistening of the fibrous web, in particular tissue web can be ensured.
- a leaching of fibers from the web is avoided, but at least reduced.
- the outer surface of the housing but at least the surface facing the fibrous web to be steamed, has a roughness of less than 10 ⁇ m.
- the outer surface of the housing, or at least the surface facing the fibrous web to be coated is polished or provided with a dirt-repellent coating, for example tetrafluoroethylene (PTFE).
- PTFE tetrafluoroethylene
- An advantageous embodiment of the steam blower box is that the surface of the housing, which faces the fibrous web to be coated and extends over the inner gas chamber and the main gas chamber with the Bedampfungsumble, in a uniform distance of about 5 to 30mm, preferably 15 to 25mm, is arranged to be steamed fibrous web.
- An alternative embodiment of the steam blow box is that the Bedampfungsumble or the surface of the housing of the main steam chamber, which faces the steamed fibrous web is disposed at a smaller distance from the moving fibrous web, as the surface of the remaining housing in which the inner Gas chamber is located.
- the Bedampfungs sumble or the surface of the housing of the main steam chamber of the remaining surface in front of a certain distance.
- a further alternative embodiment in contrast to the previous embodiment is that the Bedampfungsumble or the surface of the housing of the main steam chamber is set back from the other surface at a certain distance. This means that the steaming section in a larger Distance from the moving fibrous web is arranged.
- the steam blower box according to the invention is, as already mentioned, preferably usable for tissue webs. It is particularly suitable for use in the production of tissue webs with high air permeability and with a basis weight of equal to / less than 30 g / m 2 .
- the steam blower box according to the invention an increase in the dry content and a regulation of the moisture cross profile can be achieved very efficiently without the environment and the steam blower itself being excessively contaminated by fibers liberated during vapor deposition.
- the web production process can thus be carried out continuously.
- the quality of the produced web, in particular tissue web can be increased thereby.
- no cleaning in addition to planned cleaning intervals must be carried out, which among other things, the runnability (web run property) is significantly improved.
- the invention will be explained in more detail with reference to an embodiment. In a rough schematic representation:
