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： The method and an arrangement are for improved impregnation of chips in association with the manufacture of chemical cellulose pulp. Un-steamed chips are fed into an impregnation vessel (30) in which a fluid level (LIQ_LEV) is established under the highest level (CH_LEV) of the chips. An improved impregnation arrangement for the chips is obtained by the addition of impregnation fluids (BL1/BL2/BL3) with increasing temperatures at different heights (P1, P2, P3), and by the establishment of a counter-flow zone (Z1) in the uppermost part of the impregnation vessel. The requirement for steaming may in this way be dramatically reduced while at the same time the amount of expelled waste gases may be minimized. A major part of the volatile compounds present in the wood are bound to the impregnation fluid (REC) that is withdrawn.

摘要： A washer for washing a fiber suspension includes a porous surface traveling in a running direction and having a width in a direction transverse to the running direction. The porous surface is configured for carrying the fiber suspension thereon. A shower includes a pipe extending parallel to the width of the porous surface. The pipe has a sidewall with a longitudinally extending slot therein. The shower further includes a pair of lips connected to the pipe. The lips are positioned immediately adjacent to and on opposite sides of the slot, thereby defining a slot nozzle with a discharge gap. The lips are movable toward and away from each other to adjust the size of the discharge gap.

摘要： A method for refining lignocellulose-containing material into pulp in a disc refiner comprises preheating the material to a temperature greater than the glass transition temperature of lignin in the material, and holding this temperature for under one minute. The heated material is then subject to high speed refining in a disc refiner to produce pulp. The resulting pulp may then be subject to secondary refining steps to produce paper quality pulp. The preheat retention time is preferably in the range of 5-30 seconds, and can be controlled as a process variable to optimize energy savings, pulp strength, and optical qualities. High quality pulp can be obtained with preheat at high temperature and low retention time, followed by primary refining at disc speed of at least 2300 rpm.

摘要： Low temperature steaming and slurrying of wood chips results in significant improvement in treatment, the chips being maintained at a temperature below 110.degree. C. (more desirably at about 105.degree. C. or less, and most desirably at about 100.degree. C. or less) until actually heated to cooking temperature. Steaming may be accomplished utilizing a vertical chip bin with one dimensional convergence and side relief or a horizontal steaming vessel, the steaming device connected to a high pressure feeder. A pump having an NPSHR less than the NPSHA may be used for drawing slurry into the high pressure feeder from the steaming device, or a pump may be disposed between the steaming device and the high pressure feeder for forcing slurry into the high pressure feeder through a conduit including a radiused elbow. The steaming is practiced at a pressure of 5 psig or less, preferably substantially atmospheric steaming is practiced. The pulp produced typically has strength properties at least about 10% greater than the pulp produced from material where it is steamed and slurried at temperatures in excess of 110.degree. C.

摘要： A method for making lignocellulose fibers, which may be optionally coated with a suitable thermoplastic, wherein the starting materials may be chosen from a wide variety of generally non-recyclable contaminated wood, paper, and/or plastic products. A mixture of the preferred lignocellulose material characterized by a relatively low moisture content and the desired thermoplastics is refined and comminuted in a steam atmosphere which is at a temperature, pressure, and duration sufficient to soften both the lignin within the wood chips and the thermoplastic polymer. The temperature of the steam atmosphere is relatively high because of the use of dry wood chips which do not result in excessive vaporization during heating. The comminution of the mixture occurs by auguring the mixture between counter-revolving dual refining discs in the elevated temperature, pressurized steam atmosphere. Upon passing through the dual revolving refining discs, the wood chips are continually abraded so as to result in the formation of fine fibers of the lignocellulose material, while the softened thermoplastics are concurrently refined so as to adhere uniformly around each of the abraded lignocellulose fibers. After passing through the refining discs, the fibers are cooled resulting in the formation of uniformly coated lignocellulose fibers, which may be used to form a variety of consolidated fiberboard products, such as by hot pressing or cold pressing operations.
摘要翻译：制备木质纤维素纤维的方法，其可以任选地涂覆有合适的热塑性材料，其中起始材料可以选自多种通常不可回收的被污染的木材，纸和/或塑料制品。优选的具有相对较低水分含量的木素纤维素材料和所需热塑性塑料的混合物在蒸气气氛中被精炼和粉碎，所述蒸汽气氛处于温度，压力和持续时间以足以软化木屑和木质素中的木质素和热塑性聚合物。由于使用在加热时不会导致过度蒸发的干木屑，所以蒸汽气氛的温度相对较高。混合物的粉碎是通过在升温的加压蒸汽气氛中搅拌反旋转双精炼盘之间的混合物。当通过双旋转精炼盘时，木屑不断磨损，导致木质纤维素材料的细纤维的形成，同时软化的热塑性塑料同时精制，以便均匀地粘附在每一个磨损的木质纤维素纤维上。在通过精制圆盘之后，纤维被冷却，从而形成均匀涂覆的木质纤维素纤维，其可用于形成各种固化的纤维板产品，例如通过热压或冷压操作。

摘要： A method of digesting lignocellulose materials impregnated with solutions of hydroxides or salts of alkali or alkaline earth metals, the ratio by weight of the solution retained during the impregnation and the dry matter being less than 2, in a digester, characterized by subjecting the impregnated materials before the digestion to a treatment with live steam under a pressure equal to or greater than that present in the digester so that a part of the steam, by giving off its sensible heat to the impregnated material and condensing, assures the preheating and penetration of the impregnation liquor up to the center of the material. The time of digestion is shorter and the pulp obtained more homogeneous.
