Chemical Packing  >>> Ceramic Random Packing >>> Cascade Ring
 
Series of ceramic random packing have been developed since 1972, applying in various industries, e.g. chemical, petrochemical, fertilizer, fine chemicals and environmental protection industries. Several patents of our products or production were granted by national authorities.


Ceramic Cascade Ring

Ceramic Cascade Ring is a kind of random packing further developed on the basis of Pall Ring and Raschig Ring. The ratio of ring height to its diameter is ½ and a conical rolled edge is added to the ring’s end.

The ring’s height is decreased and tube wall is thinned. Due to the additional conical rolled edge, the mechanical strength of the ring is improved and the ring’s symmetry is destroyed. Therefore, accumulation voidage is increased significantly. The resistance to vapor is decreased and flux is increased a lot when vapor-liquid flows through the packing bed. Distribution of vapor-liquid is distributed more evenly and the interface between vapor and liquid is increased so as to improve the mass transfer efficiency.

With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, Cascade Ring can resist high temperature, acid (except HF), alkali, salt and various organic solvents. It's widely applied in various packing towers of desiccation, absorption, cooling, washing, and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation.

陶瓷阶梯环吸收了陶瓷拉西环的特点,而对鲍尔环的改进,环的高径比为1:2,并在一端增加了锥形翻边,减少了气体通过床层的阻力,并增大了通量,填料强度较高,由于其结构特点,使气液分布均匀,增加了气液接触面积而提高了传质效率。陶瓷阶梯环也改变了拉西环填料的环高与直径相等的习惯,降低了环的高度,减薄了材质的厚度,并在阶梯环的一侧端增加了翻边。由于阶梯环填料的一侧端增加了翻边,不但可以增加填料环的机械强度,而且由于破坏了填料结构的对称性,因而增加了填料投放时的定向几率。又由于翻边的影响,使得填料在堆积时填料环隙之间的接触由此线性接触为主变为以点接触为主。这样,不但增加了填料颗粒之间的空隙,减少了气体穿过填料层的阻力,而且这些接触点还可以为液体沿填料表面流动的汇聚分散点,从而促进了液膜的表面更新,有利于填料传质效率的提高。因此,陶瓷阶梯环填料的性能较陶瓷鲍尔环又有了进一步的提高
