Detailed Description

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.
