METHOD AND SYSTEM FOR DETERMINING THE HYDRAULIC/MECHANICAL LOADING OF CELLULOSE WEBS
The invention relates to a method for assessing the hydraulic/mechanical loading of a cellulose web during production. The method is primarily characterized in that, by means of an optical system, a measured variable is formed which describes the level of unevenness or the depths of the furrows in the cellulose web. The invention further relates to a system for carrying out the method, in which an optical system comprising an illumination device (19), a camera (17), and a control system is provided. By using such a method and such a system, the causes of breaks and delaminations of cellulose webs can be detected at an early time and can be counteracted accordingly in order to prevent breaks or delaminations.
The invention relates to a method for producing a fibrous material web (9), particularly for producing a tissue or hygienic paper web, in which a fibrous material suspension is dewatered in a twin wire former (18) to obtain a fibrous material web (9), and said fibrous material web (9) is dried with the aid of a TAD dryer (19). After the twin wire former (18) and before the TAD dryer (19), a pre-dewatering device (20) is provided which comprises a hood (17) and a suction roller (16), a hot fluid flow passing through the fibrous material web (9) that is embedded between one covering (3, 4, 5) on each side. The covering (5) between the suction roller (16) and the fibrous material web (9) is a felt (5), and the covering (3, 4) between the fibrous material web (9) and the hood (17) is a screen (3, 4). In said pre-dewatering device (20), a specific volumetric fluid flow greater than 100 m3/ (m2.min), particularly greater than 200 m3/ (m2.min), and preferably greater than 250m3/ (m2.min) is sucked through the fibrous material web (9).
The invention relates to a method for producing a fibrous material web (9), particularly for producing a tissue or hygienic paper web, in which a fibrous suspension is dewatered in a crescent former (10) to obtain a fibrous material web (9), and dried on a Yankee (6). After the crescent former (10), the fibrous material web (9) is guided along with the forming screen (3) and felt (4) over a suction roller (11) downstream of the forming roller (2). The invention also relates to a device for carrying out the claimed method.
The subject of the present invention is a method for processing metallized packaging materials, especially beverage cartons, or blister packaging.
According to the invention, the aluminum is dissolved with the aid of acid and separated from the plastic. The metal-containing acid solution then undergoes pyrohydrolytic treatment and the acid is thus recovered. The aluminum can be recovered as valuable aluminum oxide.
A hydrocyclone with an inflow region providing tangential inflow for a feed slurry and with a separation region following the inflow region with an underflow discharge pipe to carry off heavy materials and with an overflow nozzle in the form of an immersion tube projecting axially into the interior of the hydrocyclone. Another inflow is provided in the area of the tangential inflow to supply the barrier fluid, where the barrier fluid and the feed slurry are separated from one another by a lamella in the hydrocyclone before they are brought together. The separation region includes a conical section and a subsequent cylindrical section above the underflow discharge pipe.
The invention relates to a method for the dewatering of sludge on a screen, wherein a flocculant is admixed with sludge, whereafter the sludge is at least partially dewatered, the flow behavior of the sludge on the screen being optically detected and the amount of flocculant to be admixed being set according to the free screen surface in a control region. The invention is primarily characterized in that the control region is arranged at a point of the cleaned screen in the inlet area of the sludge, for example at the edge. The invention also relates to a device for the dewatering of sludge, comprising a flocculant feed device and a screen downstream of the flocculant feed device, wherein a device, in particular a camera, is provided for optically detecting the flow behavior of the sludge and is connected via a control system to the flocculant feed device for regulating the amount of flocculant, said device being characterized in that the device (11), in particular the camera, is designed such that it detects a control region in the inlet area (10) of the cleaned screen. In this way, regulation can be achieved for an optimal feed amount of flocculant in a straightforward manner regardless of the material feed and the sludge type.
The invention relates to a device (1) for producing a galvanized, thin strip-cast steel strip (12), comprising a pickling section (5), a re-rolling stand (6) and a galvanizing line (9). According to the invention, the galvanizing line (9) is an electrolytic galvanizing line (9), and the pickling section (5), the re-rolling stand (6) and the electrolytic galvanizing line (9) are mounted one after the other without a treatment station for thermally treating the steel strip (2) being interposed. The invention also relates to a method for producing a galvanized, thin strip-cast steel strip.
