Electrostatic Precipitator
(ESP) is the most efficient dust collecting
equipment among various types of Pollution
Control equipments. ESP can achieve high efficiency
against small pressure drop even for sub micron
particles. Efficiency in excess of 99.9% for
ultra fine dust is very common and can be
used over wide range of applications.
An ESP consists of high Voltage (HT) discharge
electrodes and adjacent dust collecting electrodes
plates. With increase of HT Voltage, negative
potential electrons will flow across the space
between collecting electrodes which are earthed
(positive) with sufficient intensity of electron
flow dust particles in gas passing between
the collecting plates are charged negatively
(-ve) and are attracted towards the earthed
collecting electrodes and give up the charge
to get collected on collecting Electrode plates.
Deposited dust is then dislodged by means
of rapping at preset intervals to hoppers
below CE plates for eventual disposal by dust
disposal system.
ESP is used extensively in Steel, Power, and
Metallurgical and Cement Industries due to
its very high efficiency at low running cost.
APC System & Products Pvt. Ltd. can provide
complete system with ESP with all electrical
fan and controls dust disposal systems, motorised
dampers etc. as per Clients requirement. Our
vastly experienced engineers can promptly
provide most economical solution and tailor
made design and size of ESP which will meet
the emission level of dust stipulated by the
Pollution Control Board.
