摘要： A sand layer is fluidized by a gas stream or current in a fluidized bed dryer and indirectly heated by immersed stationary heat-exchanger tubes. The sludge to be dried is continuously fed under pressure in a pumpable conditon from above onto the fluidized sand layer. The sludge is coagulated in the fluidized sand layer to form sludge lumps. Here, the sludge lumps are successively dried from the surface down to the core thereof, and the already dried layers of the sludge lumps are successively abraded by the fluidized sand, whereby the sludge lumps are entirely comminuted and the dry matter thereof is pulverized to form dust. This product dust is continuously discharged together with the exhaust-gas stream from the fluidized bed dryer and continuously separated as a product from the exhaust-gas stream. The gas stream or current freed from dust is partially recycled in a closed circuit back to the fluidized bed dryer for fluidization of the sand layer.

摘要： The bleaching chemicals are added to the pulp immediately after heating of the raw pulp thickened to more than 20% by weight and immediately prior to a dispersing process. This is carried out in a high-speed, high-efficiency disperser, where the heated, thickened pulp is forced through a plurality of narrow slits in a disperser lining and is exposed to strong shearing, impact and kneading stresses. In this way, the dispersing process is reduced to a time period less than 3 seconds, preferably about 1 second or less. As a result, the total time required for reductive bleaching is reduced to less than 15 seconds and no further measures are required for displacing and excluding air from the system. The method can also be advantageously used with oxidative bleaching at reduced reaction time requirements. A high dispersing temperature in the region of 40.degree. C. to 110.degree. C., preferably about 95.degree. C. is possible and there are essentially simultaneously carried out the bleaching and dispersing actions without the need for separate dispersing stages and large reaction towers and pumps.
摘要翻译： 漂白化学品在加粗粗纸浆之后，立即在分散过程之前立即加入纸浆中，加浓至20重量％以上。 这是在高速，高效率的分散机中进行的，其中加热的加稠的纸浆被迫通过分散机衬里中的多个狭窄的狭缝，并暴露于强的剪切，冲击和捏合应力。 以这种方式，分散过程减少到小于3秒，优选约1秒或更短的时间段。 因此，还原漂白所需的总时间减少到少于15秒，并且不需要进一步的措施来排除和排除系统中的空气。 该方法还可有利地用于减少反应时间要求的氧化漂白。 在40℃至110℃，优选约95℃的区域中的高分散温度是可能的，并且基本上同时进行漂白和分散作用，而不需要分开的分散步骤和大的反应塔和 泵。

摘要： In a headbox system for a papermaking machine with an adjustable distribution of the fiber stock suspension or pulp over the web width, the flow in the delivery slice is controlled in such a way that, across the web width, also the distribution of the fibers in respect of fiber orientation and quantity has a desired profile. For this purpose, the flow of the fiber stock suspension is controlled such that in the event of a change in the distribution of the fiber stock suspension across the web width, the horizontal component of the flow direction in the delivery slice remains, at all locations, always in the predetermined machine direction and thus transverse flows are avoided and the flow rate in the delivery slice has a predeterminate profile.

摘要： Process and apparatus for the separation of solid matter via flotation. The flotation process for the separation of solid matter from a suspension takes place via the utilization of centrifugal forces wherein the suspension is brought into rotation in a separating zone so that the floated components are particularly effectively routed to and concentrated at the center of the separating space, whereby, when viewed axially, floated components and the remaining portion of the suspension is guided in the same direction and out of the separating zone, with the avoidance of vortexes in the flow stream achieving particularly favorable separation effects. In addition, several apparatuses, for carrying out the process, are also set forth.

摘要： The proposed multilayer head box for a paper machine or similar is constructed so that it can produce a wide jet consisting of at least three individual jets (5, 5', 5") The individual jets are fed through separate channels (3, 3", 3") and emitted out of the head box and subsequently combine to form a single wide jet. The individual channels are so constructed that further outer lying jets can be diverted sufficiently after having been emitted out of their respective channel, so that they meet the respective further inner lying partial stream at a very slight angle. The problem of separation when the partial streams are diverted as well as that of undesired lateral mixing when the partial streams are combined are thereby prevented.

摘要： A method of removing fine contaminants from waste paper fibrous material (S) is described with solution (1) and pre cleaning (2) whereupon the fibrous material is first subjected to a washing treatment (3) and then to a flotation treatment (5). The washing filtrate (12) from the washing treatment (3) is cleaned in a filtrate-flotation treatment (4) so that a cleaned fraction (14) can be returned into the useful material (13) of the washing treatment. The so cleaned waste paper fibrous material can be passed to further treatment steps such as flotation, bleaching and/or dispersion. The reject material from the filtrate-flotation (4) is, in one embodiment, again subjected to a flotation treatment.

摘要： A roll for the thermal treatment of a web of material (4) in which the web of material (4) is cooled to a defined predetermined temperature in a gap (5) between the roll (1) and a counter-roll (2) is formed as a deflection controlled roll with a rotationally fixed carrier (8) and a rotatable roll jacket (10) which is supported relative to the latter with support elements (11). The roll jacket consists of a plurality of concentric zones, an inner soft zone (16) and a thin outer zone (17) with good thermal conductivity, for example of metal. The roll surface (22) is for example cooled with cooling gas nozzles which are regulated by a temperature sensor (20) so that the roll temperature in the gap (5) adopts a defined temperature value. A roll of this kind is for example suitable for use in a calender for the smoothing of a paper web or also for the processing or manufacture of a plastic foil.

摘要： An apparatus is provided for mechanical thermal dewatering of a web of fibrous material (1). The object is to provide a dewatering apparatus which delivers better drying results while precluding delamination of the web (1) of fibrous material. This is achieved in an apparatus in which the web of fibrous material is passed through at least two press surfaces (2, 3) which form a press gap and which exert the dewatering pressure on the web of fibrous material by forming one press surface (2) as an impermeable band (4) which can be pressed towards the other press surface (3) via a hydraulic pressing element means (15). A support pocket (5) is located in the pressing element essentially in the region between the web inlet end and the center of the pressing element means (15) and is effective to generate a hydrodynamic pressure field at the pressing element means (15) by setting a lubricant into circulation. The hydrodynamic pressure field provides the desired pressure characteristic as the web of paper material passes through the press zone.
