Electrostatic Dust Collector

The working principle of the electrostatic dust collector is to use the high
voltage electric field to ionize the flue gas. The dust charge in the air flow
is separated from the air flow under the action of the electric field. The
negative electrode is made of metal wires with different cross-sectional shapes
and is called a discharge electrode.

The positive electrode is made of metal plates of different geometries and is
called a collecting electrode. The performance of an electrostatic precipitator
is affected by three factors, the nature of the dust, the configuration of the
equipment, and the flow rate of the flue gas. The specific resistance of dust
is an index for evaluating conductivity, and it has a direct effect on the dust
removal efficiency. The specific resistance is too low, dust particles are
difficult to maintain on the dust collecting electrode, causing it to return to
the air flow. The specific resistance is too high, and the dust particles that
reach the dust collection electrode are not easily released. A voltage gradient
between the dust layers can cause partial breakdown and discharge. These
conditions will result in a drop in dust removal efficiency. The basic
principle of electrostatic precipitators is to use electric power to trap dust
from the fumes, which mainly includes the following four interrelated physical
processes:
(1) The ionization of gas.
(2) The charge of dust.
(3) Charged dust moves to the electrode.
(4) Charged dust collection.
Charged dust trapping process: on the metal anodes and cathodes with large
differences in radius of curvature, an electric field sufficient to ionize the
gas is maintained by high-voltage direct current, and the electrons generated
after gas ionization: anions and cations are adsorbed on the Through the dust
on the electric field, the dust gets its charge. Electrodes with different
polarity are moved to electrodes of different polarities and deposited on the
electrodes under the action of electric field force to achieve separation of
dust and gas.
