DESCRIPTION AND OPERATION
ATC-Series cyclones are high-efficiency dust collectors designed to eliminate airborne dust as it is generated. Contaminants are captured at the source(s), and then conveyed through ductwork to the collector where the dust is separated from the air stream and collected. The primary mode of operation is the air cleaning operation. The separated dust is discharged into a collection container. The cleaned air is then exhausted into the atmosphere or further filtered through afterfilters.
2.3
AIR FILTERING OPERATION
Normal operation consists of the air filtering operation and the resulting cleaned air discharge.
During the air filtering operation, contaminated air is drawn into the Clean Air Industries Amtech ATC Cyclone Dust Collector through the air inlet located on the upper barrel above the internal helix (see Figure 1). The contaminated air spirals down and accelerates as the cone narrows whereby higher centrifugal forces are exerted on dust particles in the air stream. As the contaminated air travels down the cone, it accelerates and the particles are thrown to the periphery of the air stream. Aided by gravity, the heavy particles are discharged into a dust-tight container (i.e. drum or hopper). As the particles drop out, the exhaust air stream spirals upward inside the downward stream of contaminated air into the fan housing and is then exhausted into the atmosphere.
NOTE: For fine dust and dust with low densities, the cyclone should be considered only as a pre-cleaner. Secondary filtration may be required.
