Tips to Tackle Industrial Air Pollution

Air pollution is the alteration of air quality that can be characterized by measurements of chemical, biological or physical pollutants in the air. Emissions from industries and factories, releasing a large amount of carbon monoxide, hydrocarbon, chemicals and organic compounds into the air are a major cause of the increasing air pollution.

However, there are numerous Air pollution control devices like compact dust collectors are available these days that quite effectively prevent various pollutants from entering the atmosphere. These control devices can be further divided into two categories - devices controlling the amount of particulate matter that escapes into the environment and devices controlling acidic gas emissions. Although complex, these devices are quite effective and have decreased the overall levels of emissions for many pollutants with their implementation.

Particulate Control - This method requires specific machinery to remove particulate matter from flue gases. Major part of this process uses physical means of separation and not chemical separation techniques. Below are some of the basic ways that particulate matter can be extracted.

Electrostatic Precipitators – This is a type of filter that uses static electricity to remove soot and ash from exhaust fumes before they exit the smokestacks. The use of static electricity removes the unburned carbon particles in smoke in the precipitators, leaving clean, and hot air to escape the smokestacks. It is essential to remove this unreacted carbon from the smoke as it can damage buildings and harm human health.

Cyclone Separators – This separation device uses the principle of inertia to remove particulate matter from flue gases. In these separators, dirty flue gas enters a chamber containing a vortex, and the difference in inertia causes the gas particles to move up the cylinder while larger particles hit the inside wall and drop down. This results in the separation of the particulate matter from the flue gas, resulting in cleaned flue gas.

Fabric Filters - These are simple filters that can be used to remove dust from flue gases. They can also be used to remove acidic gases if they utilize basic compounds. In this method some sort of fabric is placed in such a way that flue gasses must pass through it before exiting the smokestacks. This procedure causes the dust particles to be trapped in the cloth.

Scrubbers - Scrubbers are used to remove harmful gaseous pollutants from industrial exhaust gases before being released into the environment. The two main types of scrubbers are - wet scrubbers and dry scrubbers. The main difference is in the type of material used to remove the gases.

Incineration – This process is used to convert VOC emissions into carbon dioxide and water through combustion. An afterburner is used for incineration, which is built to create the conditions necessary for complete combustion (such as sufficient burn time and high temperature).

Carbon Capture - Carbon capture and storage refers to the process of capturing the carbon dioxide and storing it below ground, pumping it into geologic layers. This process is rarely being used but is talked about extensively as a way to limit greenhouse gas emissions leading to climate change.

Besides these, there are many axial flow fan dealers you can contact to get premium quality air pollution control devices installed at your facility and contribute towards a pollution-free environment.
