How to calculate and select a foam-breaking net

The foam-breaking mesh is the most traditional and simply structured method for foam removal. Nowadays, efficient air-liquid foam and mist separation elements with vanes are widely used; these elements offer advantages such as no clogging, high separation efficiency, high operational stability, high operational flexibility, low operating pressure, and the need for no replacement or maintenance of the internal components. Although the foam breaker mesh is a very primitive and simple type of foam removal element, some domestic design firms still use it by following the blueprints from the 1970s and 1980s. However, the calculation and selection for foam-breaking screens also need to be based on the dynamic separation platform; parameters such as the density of the defoaming screen, the flow area, the maximum airflow velocity, the separation efficiency, and the operating pressure drop can only be provided in a systematic and accurate manner through specialized design and calculation systems. Furthermore, it is necessary to first understand and grasp parameters such as operating temperature, pressure, gas flow rate, gas composition, gas viscosity, foam flow rate, foam density, foam viscosity, and foam surface tension before proceeding with systematic calculation, design, and selection. It’s not something that can be determined just by looking at a few simple charts or doing a quick search, as some salespeople try to claim. The supplier must be required to provide a complete and accurate process calculation sheet.
