Industrial Ventilation & General Principles
In a factory working area, ventilation
i.e. ventilation fans are basically used to control exposure to airborne
contaminants. It is majorly or commonly used to remove contaminants such as
fumes, dusts, and vapours, in order to provide a healthy and safe working surrounding
atmosphere or environment. Ventilation Manufacturing
Services can be accomplished by natural means such as opening a window
and mechanical means i.e. fans or blowers
Industrial systems or any factory are
designed to move out or a remove (exhaust) and bring in (intake) a specific
amount of air at a specific speed i.e. velocity, which results in the removal
of undesirable contaminants. Whereas all ventilation in every factory systems
follow the same basic principles, each and every system is designed
specifically to match to the type of work and the rate of contaminant release
at that workplace.
Industry facilities are often used in
places that produce toxic or unhealthy airborne particles, dangerous and
hazardous chemical fumes, dust, and other harmful vapours. To decrease the
effect of these floating dangers, proper industrial ventilation needs to be
installed. Take simply, industrial ventilation gets rid of the toxic and
unhealthy air and replaces it with fresh air from outside.
Ventilation or a ventilation fans used for
decrease the air pollution in factory environment is a necessary part of any
industrial facility that will produce harmful air pollutants in a confined
space where employees work. It not only cleans the air employees will breathe a
fresh and healthy air as compare to previous, it also allows for better
temperature control and reduces the risk of fire in the facility.
By the two main methods of industrial ventilation
used to keep employees safe – dilution and local exhaust.
Local Exhaust
When dirt levels are high, local exhaust
is used. It works by removing the contaminated air close to the source, and
then sending that air through a series of filters on its way out of the
facility. This system wants some upfront costs to set up the ducting, but it
can handle large amounts of contaminates in multiple forms.
Dilution
Ideal for situations that involve low
levels of air pollution and toxicity, dilution mixes contaminated air with
clean air from outside of the facility. Typically, big fans are mounted on the
walls and ceilings to push in the fresh air. This method doesn’t need a lot of
maintenance, which makes it a great option for mobile and dispersed sources of
contamination.
General Principles of Industrial Ventilation are given below
Lets see Environmental engineers view:
· The
design and application of equipment for providing the necessary conditions for
maintaining the efficiency, health and safety of the workers.
Industrial hygienists view:
· The
control of emissions and the control of exposures.
Mechanical engineers view:
· The
control of the environment with air flow. It can be completed by replacement of
contaminated or bad air with clean air.
