The present disclosure relates to a fine dust removal system including a conductive filter module, and more particularly, to a fine dust removal system having a conductive filter module which includes a cylindrical conductive filter to thereby implement high fine dust removal efficiency with low pressure loss and which can be easily, generally applied to and used in an air cleaner to be installed in windows or in an independent indoor air cleaner.

The following is an apparatus and a method that enables the automated collection and identification of airborne particulate matter comprising dust, pollen grains, mold spores, bacterial cells, and soot from a gaseous medium comprising the ambient air. Once ambient air is inducted into the apparatus, aerosol particulates are acquired and imaged under a novel lighting environment that is used to highlight diagnostic features of the acquired airborne particulate matter. Identity determinations of acquired airborne particulate matter are made based on captured images. Abundance quantifications can be made using identity classifications. Raw and summary information are communicated across a data network for review or further analysis by a user. Other than routine maintenance or subsequent analyses, the basic operations of the apparatus may use, but do not require the active participation of a human operator.

An electrostatic precipitator may have different collecting and repelling electrodes surfaces. For example, a collecting electrode may have an internal conductive portion. A non-conductive or less conductive open cell foam covering may be applied to the conductive core of the collecting electrode. The foam may have cell sizes that vary within the volume of the foam or along the length of the foam. Accordingly the cell size of the foam near the leading, with respect to the direction of airflow, portion of the collector may be larger than the cell size of the foam nearer the trailing end of the collector and/or the cell size of the foam near the exterior of the collector may be larger than the cell size of the foam nearer to the interior of the collector.

An electrostatic precipitator is constructed with collecting and repelling electrodes. The collecting electrode is partially shielded from gas shear forces by a shielding structure. The shielding structure is mounted to reduce gas flow along a surface of the collector and includes passages for charged particles to travel to be captured by the collector.

Improvements in active field polarized media air cleaner include an aerodynamic front cowling to reduce static air resistance, a rear double hinge to reduce blow by, a resistive center screen permitting the sharing of high voltage power supplies while reducing the tendency to arc and allowing for a higher operational voltage, a dielectric media support frame to produce a more uniform electrostatic field and reduce blow by, while at the same time reducing the tendency to spray corona and/or arc at the edges of the center screen, a substantially flat conductive outer screen to produce a more uniform electrostatic field throughout the filter media and a high-voltage shield to reduce high-voltage arcing and the spraying of corona where the high-voltage probe contacts the center screen.
