2.3 Cyclone Dust Collectors
Cyclone dust collectors use centrifugal force to separate dust particles from the air stream. As the dusty air enters the cyclone, it is forced to move in a spiral motion, causing the heavier particles to be flung to the sides and deposited into a collection bin. The cleaner air is then drawn out from the center of the cyclone and released back into the workshop or directed through a filter for further purification. Cyclone dust collectors are highly efficient and effective in capturing large and heavy particles, making them suitable for industries that generate coarse or heavy dust.
2.4 Wet Dust Collectors
Wet dust collectors utilize water as the primary filtration medium to capture and remove dust particles from the air. The incoming dusty air is drawn into the collector, where it passes through a water curtain or is sprayed with water to capture the dust. The dust settles at the bottom of the collector, while the clean air is released back into the workshop or directed through additional filters. Wet dust collectors are particularly useful in industries where the dust particles are sticky, abrasive, or combustible, as the water helps to suppress potential fire hazards and traps the dust effectively.
