Which is better for air dust removal, solid nozzles or hollow nozzles?
Could you be more specific? What kind of dust removal conditions? Solid nozzles are usually used; hollow nozzles are rare, and the best-performing ones are dual-fluid nozzles
Thank you. It’s about flue gas dust removal. I checked the design manual, and it states that for this purpose tangential hollow cone or spiral solid cone nozzles can be used; however, under the same conditions, spiral solid cone nozzles produce smaller droplets, resulting in a better absorption effect. But I’m worried that the droplets are too small, causing mist film entrainment
The spiral solid cone is quite commonly used; the droplet size is around 500–700 microns, and its atomization performance is indeed better than that of the tangential hollow cone
We also use solid spiral nozzles
