1、 Product introduction:
Metal step ring filler It is a new type of packing and an improvement on the Bauer ring. Compared with the Bauer ring, the height of the metal stepped ring is reduced by half and a conical flanging is added at one side. As the height diameter ratio decreases, the average path of the gas around the outer wall of the packing is greatly reduced, reducing the resistance of the gas through the packing layer. Conical flanging not only increases the mechanical strength of the packing, but also makes the line contact between the packing become the point contact. This not only increases the gap between the packing, but also becomes the collection and dispersion point of liquid flowing along the packing surface, which can promote the surface renewal of the liquid film and improve the mass transfer efficiency.
2、 Product features:
Metal step ring The packing reduces the height of the ring, and adds conical flanging at the two side ends of the ring, making its performance better than that of Ball ring packing. Under the same liquid spray density, the flooding point gas velocity is 10-20% higher than that of the Bauer ring; At the same gas speed, the pressure drop is 30-40% lower than that of the Bauer ring.
3、 Scope of application:
Metal step ring Especially suitable for vacuum distillation Pagoda It can deal with materials that are heat sensitive, easy to decompose, easy to polymerize and easy to form carbon.
