摘要： The invention concerns a method for the impregnation of chips during the manufacture of chemical pulp, where the chips are continuously fed without preceding steam treatment to the top of an impregnation vessel (101) that maintains atmospheric pressure. Impregnation fluid (BL) us added to the impregnation vessel (101) and establishes a fluid level LIQ_LEV. The chips that have been added establish a chips level CH_LEV that lies at least 3-5 meters over the fluid level and where the temperature at the top (109) of the vessel essentially corresponds to ambient temperature. The invention is characterised in that impregnation fluid BL is fed in to the impregnation vessel in such an amount and at such a temperature that the temperature that is established at the fluid level LIQ_LEV is established within the interval 90-115 °C, preferably within the interval 95-105 °C.

摘要： The invention concerns a system for the steam pre-treatment of chips in association with the production of chemical cellulose pulp. The vessel (1) in which the chips are pre-treated with steam (ST) is provided with a ventilation channel (2A-2B) 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 comprises a control unit (CPU) that detects a process parameter that is indicative of the fraction of moisture in the gases, preferably the temperature detected by a sensor (3), at the top of the chip bin, preferably in the withdrawn weak gases, and opens dilution lines (5a-5d) that supply air for the dilution of the weak gases in the ventilation channel.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： The invention concerns a method and an arrangement for improved impregnation of chips in association with the manufacture of chemical cellulose pulp. Unsteamed 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 counterflow zone (Z1) in the uppermost part of the impregnation vessel. The requirement for steaming can in this way be dramatically reduced while at the same time the amount of expelled waste gases can be minimised. A major part of the volatile compounds present in the wood are bound to the impregnation fluid (REC) that is withdrawn.

摘要： The invention concerns a method and an arrangement 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, where the vessel (101) has an inlet (107) for the input of chips and an outlet (201 ) for the output of a chips suspension. The chips suspension in the vessel (101) has a first fluid/wood ratio established above a second fluid/wood ratio, where the second fluid/wood ratio 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. The invention is characterised in that after the output of the chips suspension from the vessel (101) and before the chips suspension is placed under pressure for onwards transport to a subsequent digester, a frac¬ tion (Q2) of fluid is withdrawn from the chips suspension, whereby a third fluid/wood ratio is established in the chips suspension, which third fluid/wood ratio is lower than the second fluid/wood ratio.

摘要： The invention relates to a method for supplying washing liquid to a digester (1) for cellulose pulp and a subsequent diffuser washing device (2a, 2b). A high, disturbance-free production capacity can be obtained by using a common feed pump (P1) which, via a main feed line (10), supplies both the diffuser washing device and the digester with washing liquid in parallel. The first pump (P1) establishes a pressure on the washing liquid which is in the interval 2-6 bar, and is preferably 4 bar, while the second pressure level, which is established by the diffuser pump device (P2a, P2b), is in the interval 6-12 bar, but is at least 2 bar higher than the first pressure level, and the third pressure level, which is established by the digester pump (P3), is in the interval 12-25 bar. The system becomes self-regulating in the event of any operational disturbances in the flow of washing liquid and, if the pumps are appropriate, a countercurrent flow of washing liquid through the system is essentially maintained.

摘要： The invention relates to a method for the improved oxygen delignification of cellulose pulp with a medium consistency of 8-16 %. The fraction of dissolved oxygen can be maintained at a high level throughout the process by the use of high pressure, greater than 15.0 bar, and by repeated agitative mixing while maintaining the high pressure, such that as large a fraction as just over 20% of the total oxygen added is dissolved in the fluid phase, and such that the amount of oxygen in the fluid phase is maintained at a high level throughout the complete high pressure section. This means that the amount of oxygen that is dissolved in the fluid phase and that penetrates the cellulose fibres can be maintained at an optimal high level throughout the process for improved delignification of the cellulose.

摘要： A method and an arrangement for the impregnation of untreated chips during the manufacture of chemical pulp. The untreated chips are fed without preceding steam treatment into an impregnation vessel (10) that comprises an upper part (11) with a first area A1 and a lower part (13) with a second area A2 that is larger than the first area A1 by a factor of at least r2-. The chips establish in the upper part (11) a level (14) of chips that is located at a level (h) above a level (18) of fluid consisting of liquor. The chips after passage of the upper part (11) pass through a transitional part (12), where an increase in area from the first area (A1 ) to the second area (A2) takes place, and it is here that the angle of repose of the chips is reduced.

摘要： The invention concerns a method and a device for the dilution of dewatered cellulose pulp that maintains a consistency of 20-30% of 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 the granulate at a position at which the granulate is in the free fall in a stand pipe (22, 40) and above a level LiqLEV of diluted pulp in the stand pipe. A number of nozzles are arranged around the periphery of the stand pipe, directed in towards the centre 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 fibres can be avoided.
摘要翻译：本发明涉及一种用于稀释脱水纤维素纸浆的方法和装置，其维持20-30％以上的稠度。通过将纸浆粉碎成细碎的干燥颗粒，在中等浓度范围内稀释至均匀的稠度可以通过加入稀释液体的流体动力学效应进行。将稀释液加入到颗粒在立管（22,40）中自由落体的位置上，并在立管上稀释的纸浆的LiqLEV之上。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。
