They are often used as an air pollution control device to maintain or improve air ...
For dust and particulates, instruments include aerosol photometers and condensation particle counters. [3] Handheld electronic monitors give instantaneous readouts, but can experience interference from similar compounds, and the user must be knowledgeable enough to calibrate the device, and interpret its results with the specific device's ...

Roughly speaking, the dust particles and other debris spiral outward to the wall of the vessel by centrifugal force , where they fall due to gravity into the bottom of the collection bin.
Materials can be added either manually or automatically to the top of a hopper. For dust collection, it enters the hopper from a collection device. For example, baghouses are shaken or blown with compressed air to release caked-on dust from the bag. Precipitators use a rapping system to release the dirt. The crumbling dust falls into the hopper.
