In todays society, pollution is a major concern with adverse environmental effects. Asthma can be a serious issue, resulting in the narrowing of airways and can even cause excess mucus production. For many, these effects are often mild. However long exposure to particle dense environments, or untreated asthma has been known to cause serious respiratory issues that can result in death. To combat these issues and to improve atmospheric quality, various methods of particle collection can be employed with the use of dust extractors.
When we think about removing particulates, we typically think of vacuum cleaners. In principle, vacuum cleaners are basic dust extractors. Vacuum cleaners work with a suction system performing filtration. Oxygen is then filtered through the system collecting any sand or dirt in a bag, barrel or cannister. Simple filtration systems such as that of a vacuum, can be basic but effective, such as sifting gas through foam filters to collect particles.
In using this basic example, we can better understand the simple principles behind the mechanics of dust extractors. All dust extractors work with three primary steps: capture, convey and collect. Capture the particles, and then convey (transport) those particulates to a centralised collection point.
The capture and collection systems of dust extractor devices are carefully considered by manufactures in the design process, while maintaining consideration to the mechanical conveyance of these machines.
Being the most complex of the three steps to understand, the ‘conveyance’ required in these machines refers to the ducting system – their ability to maintain consistent air flow with steady velocity, enabling the dirt to be easily suspended and then filtered.
Whilst widely used, vacuums are used to collect low lying dirt and other small residue in carpets or other materials. In other cases, particles from the environment can cause significant problems, not just the low-lying matter vacuums filter. In these cases, air filtration units are used to remove dirt or sand, just like they would in a dust extractor.
As previously discussed, filtration is the simplest, most common purification method primarily used in dust extractors. Although with air purifiers, alternative methods can be implemented to eradicate germs and purify environments.
These include, but are not limited to, ultraviolet germ irradiation, activated carbon, immobilized cell technology or thermodynamic stabilization. In each of these methods, sterilization of smaller micro-particles is used in conjunction with filtration methods, found in dust extractors, to reduce particulate matter and other contaminants. Sophisticated filtration processes are continually being developed and improved upon. Some of these methods can even be used to absorb bad atmospheric chemicals.
In discussing all these methods of filtration, basic principles in improving air quality should not be forgotten. Firstly, keep your environment hygienic. Sand or dirt originates from messy environments, so start by keep your environment spotless and make cleaning a habit. Regularly vacuum or use a dust extractor and remove clutter which can trap and hold dirt.
Second, start changing filters on your cleaning devices. This removes particles that may be clogged in your machines. Another additional benefit in changing your filter, is that it reduces load on the machine during the filtration process. Likewise, with the disposal of collection cannister bins. If possible, introduce plants or other flora – plants naturally output oxygen. Finally, cycle fresh air.
The objective with dust extractors is to always remove the impurities. Cycling fresh air does this and can be as simple as opening a window. It also has the added benefit in removing mould and moisture by keeping areas well ventilated. With consideration of all these principles, and investment in a dust extractor to remove bad particles, harmful side effects from poor air quality can be removed.
