    • The invention relates to a discharge screw arrangement (12) for discharging lignocellulosic material (7) from a lignocellulosic treatment reactor (1) and comprises a discharge screw (10), a feeder pipe (11) and a blow pipe (5), the discharge screw being accommodated in and rotatably arranged inside the feeder pipe and being configured to mechanically transport the lignocellulosic material in a longitudinal direction along a rotational axis of the discharge screw through the feeder pipe towards a downstream end (14) of the feeder pipe, which discharge screw arrangement is configured to allow steam to flow through the feeder pipe to help transporting the lignocellulosic material in the longitudinal direction along through the feeder pipe and out of the feeder pipe through an outlet nozzle (24) arranged in a side wall of the feeder pipe (11) at the downstream end of the feeder pipe and into the blow pipe), wherein the discharge screw arrangement further comprises a material spreader (20), which is rotatably arranged at the downstream end of the feeder pipe and is configured to transport the lignocellulosic material in a radial direction, perpendicular to a rotational axis of the material spreader, towards the outlet nozzle,which is arranged peripherally of the material spreader, and out of the feeder pipe through the outlet nozzle and into the blow pipe.

    • 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.
    • 本发明涉及一种在制造化学纸浆期间浸渍碎屑的方法,其中将碎片连续地进料而不进行先前的蒸汽处理,以保持大气压力的浸渍容器(101)的顶部。 将浸渍液(BL)加入到浸渍容器(101)中并建立液位LIQ_LEV。 已经添加的芯片建立在流体水平上至少3-5米的芯片级CH_LEV,并且容器顶部(109)处的温度基本上对应于环境温度。 本发明的特征在于,浸渍流体BL以这样一定量的温度进料到浸渍容器中,该温度使得建立在液位LIQ_LEV下的温度在90-115℃的范围内,优选在 间隔95-105°C。
