Abstract: A scrubbing system for removing particulate from an air stream generated during a glass-wool insulation forming process includes a first separator system for removing at least a first portion of the particulate from the air stream, a second separator system, in the form of a single cloud generating vessel, for removing another portion of the particulate, and a third separator system for removing both moisture and a further portion of the particulate. The first separator system is designed to effectively provide a high residence or pre-treatment time for the air stream that enables fine particles to grow into larger particles which are easier to trap and collect, while also allowing the air stream ample time to cool to saturation temperatures. The first and third separator systems combine with the single cloud generating vessel to synergistically enhance the overall efficacy and efficiency of the scrubbing system.
