Pollution, particularly air pollution has been a bane to the world for many decades now. With rapid industrialisation that is underway in most countries right now, air pollution is at an all-time high with no sign of decreasing any time soon. Fortunately, there are certain devices that control air pollution and effectively ensure that it does not reach alarming proportions. Discussed below are the different types of devices for controlling air pollution about which you should know.
Here are the Types of Devices for Air Pollution Control
- Cyclone Separators
What a cyclone separator does is to basically use inertia to get rid of particulate matters from the gases that go out of the ducts, or flues. These devices work on the principle wherein the flue gases go into a chamber that houses a tornado-like vortex. Due to the difference in weight between the light gas particles and the larger particulates, the former goes up the cylindrical chamber and exit while the heavier and larger particulates impact with the walls of the chamber and fall down.
- Electrostatic Precipitators
This is considered by many to be the best device for controlling air pollution. An electrostatic precipitator or ESP works by using static electricity to separate ash and soot from the fumes, before letting it go out of the pipes and ducts. The particles of carbon that are left unburned are extracted out of the smoke with the help of the static electricity within the precipitators. With the help of electrostatic precipitators’ spare parts, one can ensure that they are never letting out polluting gases into the environment.
- Fabric Filters
One of the most basic forms of air pollution control devices, fabric filters, as their name suggests, uses some sort of fabric (usually felt) to trap the particles of dust before the gas goes out from the smokestacks. In comparison to the previous two methods, this technique may seem rudimentary, but it is quite effective nonetheless and does its job rather well.
Another device that is true to its name, incineration involves the conversion of VOCs, volatile organic compounds into CO2 and water through the means of combustion. This combustion occurs in specialised equipment known as ‘afterburner’. The afterburner is made in such a way that it can create the necessary conditions for combustion, including the high temperatures that are required.
- Carbon Capture
There is a theory that states that carbon dioxide can be captured and stored in geologic layers to prevent it from going out into the atmosphere. A carbon capture device puts this theory into practice. However, this is one of the more rarely used techniques but there are discussions about it constantly as a means to curb the emissions of greenhouse gases.
These are the types of air pollution control devices that are most extensively used. Their necessity in today’s world is unquestionable, and any way to limit air pollution should be considered and put into practice without too much thought.
