Dust Collecting Principle |
 |
Once the
large dust particles are eliminated by the pre-filter,
small dust particles that reach ionizing sector are positively
charged and magnetized to the negatively charged part
of the electrostatic dust-collecting panel. Resistance
formed between accumulating dust particles of the panel
and the airflow increases until dust particles detach from the panel in lumps. |
|
| These dust lumps piled up at the final
filter.Roll, Pocket or Panel Type filters are used as the final
filter. |

Structure
● Ionizing Dust-Collector
Sector
- Ionizing dust-collector sector consists of the 1st collecting
stage and the 2nd collecting stage.
- The first collecting stage is made up of the collecting
panel (ground connection) and a discharging line (ionizing
line) of DC 8-12 KV.
|
 |
|
An ionizing field
is formed between the discharging line and the collecting panel.
Passing dust particles are positively charged and at least 70%
of the initial dust particles are rapidly attached to the collecting
panel.
- The second collecting stage is an alternative setup of the
collecting panel (ground connection) and the resistance panel
with the DC 4-6 KV. It collects about 70% of the remaining 30%
dust particles that escaped the first collecting stage, collecting
at least 91% of total dust particles.
-In contrast to the other standard electrostatic dust collectors
only having the first collecting stage, FIGARO is a highly effective
two-stage dust collector with an outstanding collecting efficiency
and capacity owing to its recollecting second stage.
● Final Filter
- As the accumulating dust particles at the collecting panel
increases, the resistance to the air flow also increases.
When this resistance to the airflow becomes stronger than
the cohesion of dust particles to the panel, dust particles
eventually detach and fall from the panel in lump forms.
- Dust particles falling off the collecting panel are in large
lumps (at least 0.5 mm in diameter) making it possible for
filters of large disposal airflow and loose net can be collected
efficiently.
- Roll Type, Pocket Type, Cell Type and Panel Type filters
are usually used as the final filter.
● High Voltage Power
- High voltage power equipment supplies high voltage electricity
of DC 4 KV to DC 12 KV to the ionizing sector and the dust
collecting sector.
- Current Limit Transformer(CLT), Multiplex and Electric Power Transformer
are the 3 forms of high power equipment that is used for FIGARO
series. Also, the availability of various models from 4mA-level
(50W level) to 40mA-level (500W level) for different electric
loads allow the best selection of power pack depending on
the amount of electricity and the place being used. (AC 220V,
380V)
- A built-in (residue electric charge) discharge current circuit
devises safety by rupturing the supply of electricity as soon
as the access door is opened.

PointⅠ |
| Bosoung's FIGARO
electrostatic dust collector includes a deflecting panel, which
prevents efficiency of dust collecting caused by accumulation
of dust particles from decreasing. |
 |
| □
PointⅡ |
- There is a
small amount (5-10% NBS) of dust particles that pass through
the collecting mechanism and the final filter even after being
positively (or negatively) charged, due to the distinctive character
of the electrostatic dust collector. This small amount of remaining
dust particles is not a problem on its own but because they
are already charged with a high voltage they effectively adhere
to the duct, the coils of air conditioner and heater causing
heat-efficiency and hygiene problems over a time period.
- Bosoung's FIGARO electrostatic dust collector contains a corpuscular
neutralizer, which maintains the duct, the coils of air conditioner
and heater like the new for a long time. |
