摘要： The invention relates to a method and a device for drying a pulp web, with dewatering of the pulp web by pressing and the pulp web being guided directly on the press belt to a first transfer area for transfer of the pulp web to a transfer clothing and transfer of the pulp web in a second transfer area to a dryer. It is characterized in that the pulp web undergoes thermal drying between the first transfer area and the second transfer area. This enables production of a pulp web with improved quality characteristics and low energy consumption at the same time.

摘要： A method for coiling a metal strip that is heat-treated in a furnace immediately before coiling and fed to a coiler at an outlet speed, and then coiled at the coiler at an elevated temperature. The future outlet speed of the metal strip and the heat losses from the metal strip between the furnace and the coiler are calculated via a predictive model and the furnace is controlled by the predictive model such that the metal strip is coiled at a pre-defined temperature within a maximum deviation of +/−5° C.

摘要： 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.

摘要： The invention relates to a filter for continuous filtration of a suspension under pressure, with a pressure vessel (1), rotating filter elements (2) disposed in the pressure vessel (1), where the filter element (2) passes through one filter cycle for each rotation, with filter zones in liquid and gaseous phase, also with filtrate channels (4′) that are connected between the filter elements (2) and separate filtrate outlets (14, 14′, 215) for each filter zone, as well as a device to control the individual filtrate zones by means of a control disc (44), where the control disc (44) has filtrate outlets (114, 115) for liquid and gaseous phase. It is primarily characterized in that a venting zone (46) is provided before the filtrate outlet of the liquid phase, viewed in the direction of the filter cycle. Thus, the compressed air in the filter elements (2) and filtrate channels (4′) can be carried off and pressure-relieved in a favorable manner.

摘要： A sealing arrangement for the sealed leadthrough of rotating shafts (2) through housing bores of housings (1) comprises at least one lip seal (3, 8, 14, 15) with a sealing lip that faces toward the area normally under higher pressure. In order to extend substantially the area of application of sealing arrangements with lip seals and by doing so, to make use of the sealing arrangement to achieve its advantages of being more economical, more durable also at pressure peaks, easier to install, and easier to maintain, also at higher pressures and pressure fluctuations, the lip seal (3, 8, 14, 15) on the side (5) facing the area with higher pressure is under a constant pressure that is higher than the highest pressure occurring inside the housing (1), and a gap (7, 10) that throttles the outflow is provided between this area and the inside of the housing.

摘要： A process and a device for utilization of waste heat from a high-temperature hood in the dryer section of a paper machine. The waste heat from the high-temperature hood is applied to the waste steam and the condensate, respectively, from a steam system by means of a heat exchanger, thus improving utilization of the energy contained in the exhaust air from a high temperature hood.

摘要： Screw press, preferably for removing liquid from a material to be conveyed, comprising a screw shaft (1) complete with a helical conveying flight (2) mounted on the screw shaft (1) and a housing shell (3) surrounding it, where a transport channel (4) is formed for the material to be conveyed between the screw shaft (1), the conveying flight (2), and the housing shell (3). In order to prevent conveyed material components from adhering to the screw shaft (1), and thus uneven filling of the transport channel (4), the invention provides for the screw shaft (1) to have a surface profile (5), at least in one section of the transport channel (4).

摘要： A process for the recovery of metal oxides from a solution containing metallic salts by spray roasting of these solutions. The process is particularly suitable for spray roasting spent pickling acids. The process feeds the solution to a reactor for spray roasting of the droplets in at least two stages, where at least one evaporation stage follows at least one conversion stage to convert the metal salts to metal oxides. The device for implementing the process includes a spray roasting reactor having a first heating zone to evaporate the water and a second heating zone to convert the metal salts to oxides.
