供应供应阶梯环

阶梯环分为塑料阶梯环，陶瓷阶梯环，金属阶梯环。

阶梯环填料的侧端增加了翻边，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

阶梯环一般由塑料、陶瓷、金属做成。材质不同，结构也有所不同。金属阶梯环内筋结构同鲍尔环，舌片弯向呈叶片状；塑料及瓷质阶梯环的内筋结构与塑料鲍尔环相似，也有米字形和井字形之分。

Yuanying 阶梯环填料广泛用于石油、化工、氯碱、煤气、环保等行业的填料塔器中。

Cascade Mini Ring

Metal cascade mini ring is made of materials such as carbon steel, stainless steel or Aluminum alloy, 304, 304L, 410, 316, 316L, etc. Plastic cascade mini ring available materials include PVC, CPVC, PP, PE, PVDF. Ceramic cascade mini ring is made of alumina.

Cascade mini ring has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency and so on. It is especially suitable for rectification towers under vacuum to treat thermo sensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.

Cascade mini ring advantage

1) Reduced pressure drop

Reduced Pressure drop occurs because Cascade Mini Ring has its largest opening predominantly in the direction of the vapor/liquid flow which allows for easy passage, this reduces the pressure drop significantly.

2) Increased plant capacity

Increased plant capacity is the direct result of the result of the reduction in pressure drop that Cascade Mini Rings provide, as this moves the operating point further away from the “critical pressure drop point” at which flooding occurs. This is typically 1-2 in., wc/ft or 10-20 mbar/in). This effect allows additional vapor/liquid handling and therefore increases plant capability

3) Improved resistance to "fouling"

Improved resistance to fouling results from the directional positioning of cascade mini rings, (largest opening in direction of flow ) as any solids entering the packed bed are more easily flushed through the packing matrix.

4) Higher operational efficiency

Higher operational efficiency occurs because of the preferential orientation which ensures that in most of the ring surface are positioned vertically rather than horizontally, and this is also advantageous for mass transfer. High efficiency is dependent on as much of the available surface area as possible being effectively wetted. The underside of any horizontal surface in a packed bed or tower is naturally shielded from the liquid trickling down and is therefore not fully wetted, such dry surfaces play little or no part in the mass transfer process. Yuanying Cascade Mini Ring significantly reduces this effect, and therefore gives much higher plant operational efficiency.
