Polypropylene thorn flower ring filling for exhaust defogging layer

Polypropylene thorn flower ring filling for exhaust defogging layerA filling material composed of multiple circular rings such as ellipsoids, with a reinforcing rib added in the middle to form an "a" shape, greatly improving the compressive strength of the flower wreath (Type A considers that the effective shadow area of the original flower wreath filling overlaps by 40%, so it is changed to Type A flower wreath filling to solve the problem of overlapping parts and strengthen the strength of the filling material with a "one" support). At the same time, this packing not only has the advantages of high flow rate and low pressure of general packing, but also has a high liquid holding capacity in the packing gap, which makes the liquid stay in the tower for a longer time, thereby increasing the contact time between gas-liquid phase and improving the mass transfer efficiency of the packing.

Polypropylene thorn flower ring filling for exhaust defogging layerDeveloped by Teller AJ in 1956, it is commonly referred to as the Teller Rosette. In addition to polypropylene material, plastic flower wreath fillers also include polypropylene (PP), polyethylene (PE), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), ETFE, polyvinylidene fluoride (PVDF) and other materials.

The concept of the dehazing layer flower wreath filling is to prevent any dead corners in the flowing liquid and maximize the effective area of the filling. Due to the presence of many curved branches and junctions, the liquid can be evenly distributed in the packing layer. Plastic flower garlands have the advantages of high porosity, low blockage, high flux, and low resistance. In addition, there is a large amount of stagnant liquid in the gaps, which results in a longer residence time of the liquid in the tower and increases the gas-liquid contact time, significantly improving efficiency. The structural characteristics of it make the pressure drop of the packing very small, which can achieve energy-saving goals.
