Dry fog dust suppression systems are ideal for providing safe, clean air in facilities that handle hydrophobic materials like coal, and moisture-sensitive materials like clay, limestone, concrete, or nitrates. Because dry fog dust suppression doesn’t use surfactants, binders, or other chemicals to remove dust from the air, materials remain free of unwanted additives and operators save money by removing the need to buy these chemicals.
How Does Dry Fog Dust Suppression Work?
There are variations in dry fog dust suppression system designs, depending on the specific application. In general, these systems use water and compressed air to generate water droplets measuring between one and ten microns: about the size range of the dust particles to be removed. When the water droplets impact dust particles in the air, they stick together and fall from the air. This efficient process adds as little moisture to the air as possible, while effectively removing the dust, which results in an average moisture addition of only 0.05% of the material weight. That’s a significant improvement over plain water spray at 5% moisture addition!
Comprehensive System Design Is Key
While dry fog dust suppression is extremely efficient and effective in the correct application, its best performance comes from comprehensive system design that accounts for all of the conditions, demand, and equipment in the specific facility. For example, a dry fog dust suppression system would typically serve as a replacement to a dust collection system, but in applications where both might be needed, the system has to be engineered to prevent the collection system from sucking up the fog and lowering the total system effectiveness. Another example is the need to design the system to prevent agglomerated particles from affecting the performance of equipment like conveyors.
