适用于草类原料蒸煮的内循环逆流置换式连续蒸煮技术及装置——新一代连续蒸煮技术的开发设计

Internal Countercurrent Displacement Continuous Cooking Technology and Device Suitable for Straw Fiber Cooking:Development and Design of the New Continuous Cooking Technology——Development and Design of Continuous Cooking Process and Equipment

将DDS置换蒸煮与管式连续蒸煮技术相结合,充分利用这两种蒸煮技术的优点,形成适合植物纤维原料连续蒸煮的工艺新方法——内循环逆流置换式连续蒸煮技术。相比现有的DDS置换蒸煮和塔式连续蒸煮,该技术工艺装置结构紧凑,药液消耗低,纸浆得率高,纸浆质量好,有较高的推广应用价值。

Combining DDS displacement cooking with tubular continuous cooking technology,an internal countercurrent displacement continuous cooking technology,a new process suitable for continuous cooking of plant fibers,was developed.Compared with the traditional DDS displacement cooking and tower continuous cooking,the new process features a more compact device structure,lower chemical consumption,higher pulp yield,better pulp quality as well as higher application value.
