Lesson: A Merry-Go-Round for Dirty Air
| Students observe and discuss a cup and pencil model of a cyclone to better understand how this pollutant recovery method functions in cleaning industrial air pollution.
|
|
As environmental engineers are faced with more types of industrial pollution, they must design even more innovative techniques to prevent it. In the cyclone method of pollution recovery, dust-laden gas is whirled very rapidly inside a collector shaped like a cylinder. The swirling motion creates centrifugal forces that cause the particles to be thrown against the walls of the cylinder and drop into a collection hopper. Cyclones can remove up to 95% of solid pollutants from cotton gins, rock crushers and many other industrial processes.
