扰流棒位于纸机烘缸内部,用来提高热传导,提高干燥均匀度.当扰流棒配置正确,冷凝水达到最佳深度时,采用扰流棒不仅能提高传热速度,还能取得良好的干燥均匀度.本文主要介绍在JOCO 4000试验烘缸内安装扰流棒,从而得出达到最佳性能需要考虑的各种因素. 相似文献

带挠流棒的固定虹吸管改善烘缸的运行性能 总被引:1,自引:0,他引:1
高速纸机已成功地从旋转虹吸管转而采用带挠流棒的固定虹吸管。 许多现有的烘缸,其虹吸管是典型的旋转式的,随着纸机速度的增加,需要一定的压差来排空积累的冷凝水,若增加压差,排除率也随之增加,则需要更大的蒸汽管,更新或重新设计热泵,尺寸过小的管道容易造成管道严重的磨损、蒸汽泄漏、能量浪费、资本投资浪费、冷凝水排除不稳定以致纸页质量波动。当运行速度超过 762 m/min(2500 ft/min)时,旋转虹吸系统会不必要地浪费大量的能量,同时也影响纸机的运行性。 目前,在全球范围内,已在 200多台高速纸机上安装了固定虹吸… 相似文献

福建省南纸股份有限公司二抄车间PM3、PM4纸机为3150纸机,在1991年进行第一次改造,主要是压榨部的改造,将原来的双压区压榨改为四辊三压区压榨.2001年又引进国外新技术,对PM3、PM4纸机进行第二次改造,网部改为叠网,压光由七辊可控中高压光改为双压区软压光.随着印刷机的进步及客户对纸张质量要求的提高,及二抄车间纸机存在烘缸表面温度不均,造成纸页横幅水分不均匀,两侧水分小,吸水后纸页起皱的现象,严重影响了产品的质量,因此公司决定对PM3、PM4纸机烘缸部进行扰流棒改造. 相似文献
