How should we judge the quality of Marley cooling tower packing? To judge whether a product is good, what aspects do we usually start from? The first thing to look at is the parameter, yes, the parameter reflects a certain characteristic value of the product. We can understand the properties of fillers through parameters and get what we want. This is also our consistent selection criteria, and it is also skillful to look at the parameters. Let's take a look at it below.
There are several basic parameters in the cooling tower packing that can best reflect the advantages and disadvantages of the packing. The most important thing is the surface area of the packing, the porosity, and the cooling tower packing coefficient. We have repeatedly emphasized that many cooling tower fillers on the market are recycled materials. We should choose the packaging carefully.
(1) Specific surface area per unit volume The surface area of the filler is called the specific surface area, denoted by a, and the unit is m2/m3. If the specific surface area of the cooling tower packing is large, the gas-liquid mass transfer area provided by it will be relatively large. Therefore, the specific surface area is an important factor in evaluating the performance of the filler.
(2) Porosity The void volume per unit volume of the filler is called the porosity, expressed by e, and the unit is m3/m3, or expressed in %. The greater the porosity of the cooling tower packing, the greater the gas passing capacity and the lower the pressure. Therefore, porosity is another important indicator for evaluating the performance of cooling tower packing.
(3) Filler factor The ratio of the specific surface area of the filler to the cubic porosity, namely a/e 3, is called the filler factor, expressed as f, and its unit is 1/m. It represents the hydrodynamic properties of the filler. The smaller the f-value, the smaller the flow resistance.
