What are the various types of scrubbers that are available in the market?
by Clear Ion Clear Ion Experts Pvt LtdThe topic
of discussion that is given here already suggests that the people reading it
would have almost all the basic knowledge that is usually associated with the
scrubbers, such as that the scrubbers are majorly used in the industries as air
pollution controlling tool. The scrubbers are the most effective source of
controlling the pollution that is there in the air.
So, here
let us move to the main topic of discussion that is the various types of
scrubbers that are available to handle all the different types of pollutions
present in the air.
There are
basically three main types of scrubbers that are available in the market for
the purpose of air pollution control:
·
Wet scrubbers.
·
Electrostatic precipitators.
But
keeping it all just limited to the basic introduction will not be of benefit to
anyone obviously if one would plan to have a scrubber installed at a commercial
setup then that person would be interested in the deeper details regarding each
type of scrubber so that it would be easy to choose the right and the
appropriate type of scrubber.
So, now
we will be focusing on the detailed discussion regarding all the three types of
scrubbers that have been listed above.
In order
to start with, we will take our first move towards the Wet scrubbers reason
they being the most popular type of scrubbers that are taken into use by the people
for controlling the air pollution at the industries. Basically, as the
name suggests the wet scrubbers work towards the control of air pollution
through water or through other types of liquid agents. Talking regarding the
working procedure of the wet scrubber we can say that the liquid is generally
enclosed in a metal or composite type of container. The dirty air or the gas
passes through the liquid and the liquid absorbs all the pollutants. As a
result, this whole process the gas or the air that comes out of the scrubber is
generally cleaner and fit to be released in the environment. The wet scrubber
is also different from other types of scrubbers because the merging of liquid
with the gas gets the moisture level increased in the gas that is put to treatment
and thus as the gas is cleaned a visible cloud comes out of the scrubber.
Now
the wet scrubbers have been discussed well in detail and there
is no stone left unturned for them so we shall now further move to the
discussion related to the dry scrubbers talking regarding the dry scrubbers one
can say that the dry scrubbers are not seen using any sort of liquid for the
absorbing the contaminants. In order to make the dry scrubber work, generally,
a dry reaction material for absorbing the contaminants is mixed with the
polluted gas. The dry scrubbers are mainly used for the efficient removal of
acids from the gases.
The agent
that is used for the removal of acid from the gas is mostly made of alkaline
slurry; the slurry is used for the purpose of neutralizing the acid present in
the gas. The acid-neutralizing agent can be merged with the acid gas in two different
ways one is through the dry sorbent injection the other is through the spray
dry sorbent. In the first method, the gas is mixed directly into the alkaline
sorbent whereas in the other method the contaminated gas goes through the mist
of the sorbent.
Now, that
all the information regarding the dry scrubbers has been collected, so we can
now further move to the discussion related to the electrostatic precipitators.
Talking regarding them one can say that they are the most unique type of
scrubbers that are known for using charged energy for the removal of dust and
other contaminants from the gas. Taking as an example of these types of
scrubbers we can count on the plate precipitator. The plate is actually a metal
sheet that is charged. The plates usually run parallel along with the
piping and the gas passes through the plates in order to remove the dust.
So, this
is all the information that is associated with the different types of industrial
scrubbers that are available in the market.
