Three kinds of commonly used fillers for environmental protection, do you only know the saddle ring packing? Look slowly, look more useful and harmless!
1. Step ring packing
The step ring packing is an improvement to the Pall ring. Compared to the Pall ring, the step ring height is halved and a tapered flange is added at one end.
As the aspect ratio decreases, the average path of gas around the outer wall of the packing is greatly reduced, thereby reducing the resistance of the gas through the packing layer. The tapered flange not only increases the mechanical strength of the packing, but also causes the main contact between the packing and the point contact, which not only increases the gap between the packings, but also becomes the collection and dispersion point of the liquid flow. Filler surface. It can promote the surface renewal of the liquid film and help to improve the mass transfer efficiency.
The overall performance of the step ring is better than the Pall ring. But no saddle ring packing is easy to use.
2, the saddle ring packing
The saddle ring packing changes the curved surface at both ends of the arc saddle packing into a rectangular surface, and the sizes of the two sides are different, that is, the saddle ring packing.
The saddle ring packing does not stack when stacked, and the liquid distribution is relatively uniform. The saddle ring packing is generally made of porcelain material and its performance is better than that of the Raschig ring. It is an excellent one of the annular fillers used.
3, metal ring moment saddle filler
The annular saddle filler (known locally as Intalox) is a new type of filler with annular and saddle structure features. The filler is usually made of metal, so it is also called metal ring saddle filler.
The annular saddle packing combines the advantages of an annular packing and a saddle packing. Its overall performance is superior to the Pall ring and step ring, which is widely used in bulk packaging. But no saddle ring packing is easy to use.
