Plastic Liquid-surface Covering Ball for Water Treatment

It is a earliest development of random packing, which its height is equal to outside diameter. Raschig Ring was invented by German Chemist Friedrich Raschig in 1914, it also marks that the development of fills hds entered a scientific track. However, in the actual application, Such as ” Wall flow, Channel flow and so on” often happened in Packed bed.  

Plastic snowflake ring is a high-effciency tower packing which was named byb its shape.lt has a low specifc gravity, high flooding point, large porosity, high mass transfer unit height.Besides, this random packing has lower pressure drop, which reduces the back-pressure phenomenon and minimizes the energy consumption of the stripping process.Plastic snowflake ring is very economical.it can be applied in the chlorine and bromine production,air separation and water cooing process.  

Flat ring is also called SMR(Super Mini Ring), It s an advanced random packing in the column tower packing. It has similar structure with cascade mini ring, There is not flanging structure at the top and bottom. It can improve the packing strength through adjust the arc of internal blade. It has reasonable flow structure, low pressure drop and high mass transfer performance. Super mini ring has two main types, which names as QH-1 and QH-2.  

It was one improved ring based on Intalox ring’ s structure. The biggest improvement is that Intalox saddle’ s arc profile will be change wavy or jagged profile. meanwhile, increase some pores in the arc liquid channel’ s middle position. This structure’ s change not only increase packing’ s contacting gap, but also improve gas & liquid’ s movement and distribution in packing layer

This is an improved pall ring. The main improvement is to increase the turning over and wall thickness at both ends. Without changing the separation efficiency, the bed height can be reduced. So as to reduce the pressure drop..

It was developed by British company MTL Ltd, which also called CMR. Metal Cascade Ring is a new type of bulk packaging with the advantages of high capacity,good stain resistance and low pressure drop.Its sides have one or two beveled edges, which have hhigher mechanical strength and better gas passage than pall rings.Metal cascade rings feature a rectangular opening,curved leaves,tapered edges, and reduced height

It also called Heilex ring, crown-type raschig ring and so on. It is a new type of Perforated Packing. Wavy gas-liquid interface enlarges liquid’ s contacting area and also improve gas-liquid flow efficiency. In addition, interlacing cone type vertical structure can largely reduce towers’ packing nesting, wall flow and unevenly distribution.  

Hiflow Ring is a 3rd generation high performance tower packing which provides an optimal design of high mechanical stability, void fraction and superior mass transfer performance.
