pollution control device for casting units.
Air Pollution : The present air in atmosphere mainly
consists of gases like O2 and N2 along with other gases in
small proportions. During the manufacturing process
pollutants are generated in the form of solid particles,
liquid droplets or gases. The volume of pollutants after
discharging from production unit, mix with the air and
increase their heavy presence in the atmosphere than legally
required, is termed as air pollution. A substance in the
polluted air can cause harm to human beings and environment.
Following are the two types of sources for generation of
1. Primary Pollutants
2. Secondary Pollutants
Primary Pollutants : Primary Pollutants are directly emitted
from the process such as Ash or sulphur dioxide released
Secondary Pollutants : Secondary Pollutants are not emitted
directly. Rather, they are formed in the air when Primary
Pollutants react or inreact.
Mainly man made Primary Pollutants are as under:-
Sulphur Oxides (SOx) - Sulphur oxide is a chemical compound
with a formula S02 is produced in various industrial
processes where coal and petroleum is used.
Nitrogen Oxides (NOx) - Nitrogen Oxide is a chemical
compound with a formula NO2 is emitted during a high
temperature combustion in an industry.
Carbon Monoxide - It is a product by incomplete combustion
of fuel such as natural gas, coal or wood.
Carbon Dioxide (CO2) - Carbon Dioxide is associated with
oceanic acidification, emitted from sources such as
combustion, cement production and respiration.
Volatile Organic Compounds (VOCs) - Volatile Organic
Compounds are important outdoor air pollutants and are
another dangerous compound which is often associated with
Particulate Matter (PM) - Particulate Matter are tiny
particles of solid or liquid suspended in gas. Sources of
Particulate matter can be manmade or natural. Particulate
Matter generated by human activities such as burning of
fossil fuels in vehicles, power plants and various
Toxic Metals - Toxic metals are lead cadmium and copper.
Particulate matter formed from gaseous primary pollutants
and compounds in photochemical smog. Smog is a kind of air
pollution, a mixer of smoke and fog. Smog results from large
amount of coal burning in an area caused by a mixer of smoke
and sulphur dioxide .
For the control of Air Pollution, industry uses mainly the
following devices. They can either destroy contaminants or
remove them from an exhaust stream before it is emitted into
Mechanical collectors i.e. Dust cyclones, Multi cyclones
Electrostatic precipitators. An electrostatic precipitator
(ESP), or electrostatic air cleaner is a particulate
collection device that removes particles from a flowing gas
(such as air) using the force of an induced electrostatic
charge. Electrostatic precipitators are highly efficient
filtration devices that minimally impede the flow of gases
through the device, and can easily remove fine particulate
matter such as dust and smoke from the air stream.
Baghouses Designed to handle heavy dust loads, a dust
collector consists of a blower, dust filter, a filter-
cleaning system and a dust receptacle or dust removal system
(distinguished from air cleaners which utilize disposable
filters to remove the dust).
