摘要： A new and improved way of continuously cooking fiber material, wherein temperatures and alkaline levels are controlled to be maintained within specific levels in different zones of the digesting process in order to optimize chemical consumption and heat-economy and at the same time achieve very good pulp properties. The digesting process includes a top separator that separates the transport liquid from the fiber material and permits the fiber material to be exposed to the cooking liquid.

摘要： The method is for retrieving heat from black liquor wherein the black liquor is withdrawn from a digester in association with the production of cellulose pulp. The black liquor at the withdrawal stage maintains a first withdrawal temperature. At least a part of the black liquor is led to a heat exchanger. An exchange of heat takes place in the heat exchanger between the black liquor and a bleaching filtrate that has been obtained from the bleaching plant. The exchange of heat results in the bleaching filtrate experiencing a raise in temperature of at least 5° C., after which the heated bleaching filtrate is used in the bleaching plant.

摘要： The method increases the yield and improves the beatability of kraft pulp. During the progression of the cooking process, more than one cooking liquor with a dissolved content of hemicellulose is drawn off and then reintroduced to the last phases of the cooking process, to re-precipitate the hemicellulose on the fibers. The hemicellulose rich cooking liquors are adjusted so that they, upon being added to the last phase of the cooking process are optimized. Early dissolved hemicellulose has a longer chain length than the hemicellulose that dissolves in the cooking liquor in the later phases of the cooking process, and they also have different tendencies to precipitate on the wood chips softened in the cooking process.
摘要翻译：该方法提高了产量，提高了牛皮纸浆的打浆能力。在烹饪过程的进行期间，抽出多于一种具有溶解的半纤维素含量的蒸煮液，然后重新引入烹饪过程的最后阶段，以将半纤维素再次沉淀在纤维上。调节富含半纤维素的烹饪液体，使其在加入烹饪过程的最后阶段时被优化。早期溶解的半纤维素的长度长于在烹饪过程的后期溶解于蒸煮液中的半纤维素，并且它们也具有不同的倾向，以便在烹饪过程中软化的木片上沉淀。

摘要： The device is for the dilution of dewatered cellulose pulp that maintains a consistency of 20-30% or greater. By shredding of the pulp to a finely divided dry-granulate, dilution to a homogeneous consistency in the medium consistency range can take place exclusively through hydrodynamic effects from the addition of dilution fluid. The dilution fluid is added to granulate at a position at which granulate is in free fall in a standpipe and above a level Liqlev of diluted pulp in the standpipe. A number of nozzles are arranged around the periphery of the stand pipe, directed in towards the center of the stand pipe, obliquely downwards in the direction of fall of the granulate. It is possible through this simplified procedure to avoid completely the conventional dilution screws, and this reduces the investment costs and operating costs, while at the same time unnecessary mechanical influence of the pulp fibers can be avoided.
摘要翻译：该设备用于稀释维持20-30％或更大稠度的脱水纤维素纸浆。通过将纸浆切碎成细碎的干颗粒，在中等稠度范围内稀释至均匀的稠度可以通过添加稀释液体的流体动力学效应进行。将稀释液加入到颗粒在自由落体的立场上，并在立管中稀释的浆液的Liqlev级上方。多个喷嘴围绕立管的周边布置成朝着立管的中心朝向颗粒的坠落方向倾斜向下倾斜。通过这种简化的程序，可以完全避免常规的稀释螺钉，这样可以降低投资成本和操作成本，同时可以避免纸浆纤维的不必要的机械影响。

摘要： The method and arrangement is for the feed of a chips suspension from one vessel to a subsequent digester in a continuous cooking process for the production of chemical cellulose pulp. The vessel has an inlet defined therein for the input of chips and an outlet defined therein for the output of a chips suspension. The chips suspension in the vessel has a first fluid/wood ratio established above a second fluid/wood ratio that is established at the bottom of the vessel. The second fluid/wood ratio is at least as great as, preferably greater than, the first fluid/wood ratio. After the output of the chips suspension from the vessel and before the chips suspension is placed under pressure for onwards transport to a subsequent digester, a fraction of fluid is withdrawn from the chips suspension, whereby a third fluid/wood ratio is established in the chips suspension.

摘要： The vessel in which the chips are pre-treated with steam (ST) is provided with a ventilation channel at the top of the vessel for the leading away of weak gases to a weak gas system (NCG). A simple safety system has been installed with the aim of guaranteeing that these weak gases do not reach a level of concentration at which these weak gases become explosive. The safety system has a control unit (CPU) that detects a process parameter that is indicative of the fraction of moisture in the weak gases and opens dilution lines that supply air for the dilution of the weak gases in the ventilation channel. It is appropriate that the dilution take place in stages, where the dilution lines are opened in stages with successively increasing temperature of the weak gases.

摘要： A method for impregnating chips in a continuous digestion system with an impregnation vessel and a digester. The digestion system has a heat exchanger arranged between a first return line and a black liquor line. The heat exchanger allows a transfer of heat between the two lines. A principal part of the fluid contents of the impregnation vessel is constituted by chips moisture, steam condensate, added white liquor, and the fluid withdrawn from the top separator at the first return line, whereby the impregnation fluid in the impregnation vessel does not contain any substantial amount of black liquor from the digester. An impregnation vessel is established that is hydraulically isolated, in which the flow of fluid and the establishment of its alkali content take place without any influence from the fluid flow in the digester process.

摘要： The arrangement concerns an improved design for at least one of the cooling, dilution and washing at the bottom of a continuous digester for the production of cellulose pulp. By arranging at least one extra strainer section above the lowermost strainer section, with the addition of washing fluid or dilution fluid between the extra strainer section and the lowermost strainer section, more washing fluid can be added at the bottom of the digester without counteracting the flow of the column of chips. This provides space for the increase of production, for improvement of the flow of the column of chips, or for combinations of these effects while retaining good cooling, washing and dilution at the bottom of the digester.

摘要： Chips are sluiced from a low-pressure section to a high-pressure section with a sluice feeder. The fluid that is used to expel the chips from the sluice feeder principally includes pressurized fluid withdrawn from the treatment vessel. This pressurized fluid is normally withdrawn from the treatment vessel for recovery (REC). By using this pressurized fluid instead for expelling the chips from the sluice feeder and subsequently sending the previously pressurized fluid to the recovery system (REC), the requirement for high pressure pumps that consume large quantities of electrical energy can be considerably reduced.

摘要： The invention relates to a feed arrangement for feeding chips to chip bins (1) in the production of cellulose pulp in continuous digesters (16), in which the chip bin is constituted by a treatment vessel having a top and a bottom, in which the chips are fed into the top (13) of the treatment vessel and fed out via the bottom of the treatment vessel using suitable lock members (10, 11). Distribution devices (4a, 4b) for the addition of steam are disposed in the treatment vessel so as to heat the chips to a level above 80° C., preferably around 100° C., when the chips are fed out via the bottom of the treatment vessel. By virtue of the fact that the chips are fed into the treatment vessel via at least one liquid lock (30) and the treatment vessel is otherwise sealed off, the quantity of driven-off gases from the chip bin is reduced to a minimum, at the same time as an effective utilization of available energy is obtained.
摘要翻译：本发明涉及一种用于在连续消化器（16）中生产纤维素纸浆中的芯片仓（1）中供给碎屑的进料装置，其中切屑仓由具有顶部和底部的处理容器构成，其中碎片进料到处理容器的顶部（13）中，并使用适当的锁定构件（10,11）经由处理容器的底部送出。在处理容器中设置用于添加蒸汽的分配装置（4a，4b），以便当芯片通过以下方式送出时将芯片加热至高于80℃，优选约100℃的水平处理容器底部。由于芯片经由至少一个液体锁（30）进料到处理容器中，并且处理容器被另外密封，所以来自切屑仓的排出气体的量减少到最小，在同时获得有效利用可用能量的同时。
