What is the packing factor of 50mm diameter ceramic pall ring?
φ 50 mm dry fill factor is 252/m,
φ 25 mm dry fill factor is 565/m,
φ 38mm dry packing factor is 365/m,
φ 80mm dry filler factor is 146/m.
The filler factor refers to the ratio of the specific surface area of the filler to the third power of the porosity, that is, a/e3, which is called the filler factor. The ceramic Raschig ring packing factor is divided into dry packing factor and wet packing factor. When the ceramic Raschig ring packing is not wetted by liquid, a/e3 is called the dry packing factor, which reflects the geometric characteristics of the packing. On the contrary, when the surface of ceramic Raschig ring packing is wetted by liquid, its surface will be covered with liquid film; At this time α And e will change accordingly α/ e ³ It is called wet packing factor, which means that the smaller the hydrodynamic property f value of ceramic Raschig ring packing is, the smaller the flow resistance is.
The ceramic pall ring is made of ceramic material, so we can also call it porcelain pall ring. Its raw materials are mainly Pingxiang and other local mud ores, which are processed through raw material screening, ball mill grinding, mud filter pressing into mud lumps, vacuum mud refining equipment, molding, entering the drying room, high-temperature sintering, and other production processes.
Ceramic pall ring packing is a kind of tower filling material, which has acid and heat resistance, high and low temperature resistance, anti-aging characteristics, and can resist the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid (HF). It can be used in various high and low temperature occasions.
Scope and characteristics
Because the ceramic pall ring is sintered into ceramics, it has acid resistance and heat resistance. It is widely used in washing tower, cooling tower, acid recovery tower, desulfurization tower, drying tower and absorption tower, regeneration tower, strip washing tower, absorption tower, cooling tower and drying tower in metallurgy, chemical industry, fertilizer, acid production, gas, oxygen production, pharmacy and other industries
Function of Pall Ring Packing
What is the role of the Pall ring? Pall rings are used in various types of packed towers. The types of pall ring packings will vary according to the material and the corresponding performance. No matter what kind of material is used, Pall ring has the characteristics of high specific surface area utilization, small air flow resistance, uniform liquid distribution, high mass transfer efficiency, and different materials have slightly different performance. For example, ceramic pall rings have good corrosion resistance, plastic has good temperature resistance, large operating flexibility, and metal pall rings have good antifouling effect.
