Particulate
matter (PM) is the most spread pollutants in the air and it is one of the six
criteria air pollutants. So it is very important to remove them from exhaust
gases before prior to emission. Cyclone separators are mostly used as an
alternative method to remove PM from the exhaust gases. They can be the main
treatment system or appropriate to use as preliminary equipment as needed.
There is a most important parameter for a cyclone, named as pressure drop. This
parameter directly effects PM collection efficiency and maintenance costs. So,
this study focused on pressure drop parameter.
The geometry of
cyclone separator is one the most important parameter that has effect on
pressure drop. Especially, the inlet and outlet parts are the areas where the
pressure drops occurs most. In present study, the effects of inlet height and
outlet pipe length on pressure drop were investigated. The increasing particle
concentration in the waste gas has a decreasing effect on the pressure drop.
Therefore, the studies were carried out with clean pressure drop. The research was performed in Yıldız
Technical University, Environmental Engineering Laboratory. Experiments were
conducted in five flowrates to see effects of different flowrates.
As a result of
the experiments, it was determined that, independently of geometry, pressure
drop increased with increasing gas flowrate. The rising trend is similar for
all geometries. The inlet height is a factor that determines the gas inlet velocity.
Therefore, it has a clear effect on the pressure drop in the cyclone. The
effect of the outlet pipe length was found to be quite weak compared to the
inlet height.
