产品介绍

结构特点:鲍尔环填料是在拉西环基础上改进的高效散装填料,环壁均匀开设了多个长方形窗孔,窗孔的叶片向内弯曲并与环壁相连,既保留了环形结构的稳定性,又打破了环壁的封闭性,使气液两相可通过窗孔自由流动,大幅提升了传质效率。常见材料包括金属、塑料和陶瓷,不同材料的鲍尔环在保持核心结构一致的前提下,适配不同工况需求。

  • 性能优势
    • 金属鲍尔环:采用碳钢、不锈钢(304、316 等)制成,机械强度高、耐高压、耐高温,能适应高负荷、高温度波动的工业环境,传质效率稳定,适用于高压蒸馏、加氢反应等严苛工况。
    • 塑料鲍尔环:以聚丙烯(PP)、聚乙烯(PE)、聚氯乙烯(PVC)等为原料,重量轻、耐腐蚀性能优异(尤其耐酸碱),成本较低,安装便捷,适用于中低压、腐蚀性介质的吸收、洗涤等操作。
    • 陶瓷鲍尔环:由氧化铝陶瓷等材料制成,具有极佳的耐高温性、耐化学腐蚀性和耐磨性,不与酸碱等强腐蚀性介质发生反应,适用于高温、强腐蚀环境下的干燥、吸收等过程。
    • 共性优势:窗孔结构减少了气液流动阻力,增加了气液接触面积和扰动程度,传质效率较拉西环提升 30% 以上;空隙率高,操作弹性大,不易发生堵塞,使用寿命长。
  • 应用领域
    • 金属鲍尔环:广泛应用于石油化工、煤化工的高压蒸馏塔、加氢裂化塔、催化重整塔等。
    • 塑料鲍尔环:适用于环保、制药、食品行业的酸碱吸收塔、废气净化塔、水处理塔等。
    • 陶瓷鲍尔环:常用于硫酸、硝酸等化工行业的干燥塔、吸收塔,以及高温烟气处理塔等。
