Dust Collectors and Clean Air: The Correlation
With all the carbon emitted into the atmosphere by vehicles, as well as the natural occurrence of dirt, dust is eventually accumulated on different areas of the home. This brings forth the importance of modern technology such as dust collectors. In layman’s terms, dust collectors are defined as devices that collect dust from visible surfaces to hard-to-reach areas. These can be in the form of miniature vacuums that can be held on one hand and is small enough to get into the tiny spaces between the furniture and the wall. These are also made of lightweight material so the corners of the ceiling can easily be reached without much pressure on the upper arms.
A more widespread purpose for dust collectors is the machinery that are designed to collect air impurities and harmful gas from the atmosphere. There 4 main components to this type of dust collecting system:
2. Dust Filter
3. A system that cleans the dust filter automatically
4. Dust receptacle
There are 5 types of dust collectors that are used for various industrial purposes:
- Inertial separators – a type of gas collector that separates gas streams from dust by combining centrifugal force with gravitational as well as inertial forces.
- Fabric filters – these dust collectors also separate gas from dust particles, but with the use of a filtration system that’s more commonly known as bag-houses.
- Wet scrubbers – a dust collection system that makes use of a scrubbing liquid that removes dust particles from gas streams.
- Electrostatic Precipitators or ESP – separates the dust particles clinging to exhaust gas with the help of electrostatic forces.
- Unit collectors – out of the various types of dust collectors, this is the only one that is portable enough to be transferred from one point to another. Unit collectors are more commonly used in bins and transfer points for belt-conveyors in remote areas.
The selection of a dust collector should always be in reference to the following factors:
1. The size of dust particles and its area of concentration.
2. The amount of dust that has to be collected. This depends mostly on the risk factor of the dust that needs to be collected and how it would possibly affect the health of the general public.
3. Airstream characteristics.
4. Dust characteristics. Note that silica and metal ore dust are abrasive so therefore not compatible with centrifugal dust collectors. Likewise, hygroscopic dust can damage bag-houses, and fabric collectors do not have the capacity to collect certain dust sizes and shapes.
5. Disposal methods. Note that there are two ways in which collectors unload their cargo: in a continuous stream or in separate batches.
No matter what type of collector is preferred, one very undeniable fact is that dust collectors play an important role in maintaining the cleanliness of the air that’s so vital for human survival.
