1. Introduction
You are about to install and operate a SMOG-HOG® PSG
operating on the principle of electrostatic precipitation. PSG
removes submicron, airborne particulate with high efficiency and
at a uniquely low expenditure of energy. With proper handling
and installation, the PSG becomes a powerful tool in controlling
objectionable emissions from a wide range of processes.
The PSG can vary in options, consisting of working groups
of collection components which may, in turn, be preceded or
followed by complimentary conditioning equipment. The PSG
may take the form of a simple component cabinet for inclusion in
a large air handling system or may be a self-sufficient air pollution
control package. Since the PSG generally becomes an integral
part of a process exhaust network, installation should be carefully
planned, starting with mechanical layout drawings and electrical
wiring diagrams provided by Parker. Reading this manual is
important to the successful installation and operation. The PSG
Series has been built to rigid specifications. As with all precision
equipment, the system requires periodic care and maintenance.
This manual contains instructions for standard maintenance and
manual cleaning of components. If the system is equipped with In
Place Cleaning, there is a separate owner’s manual. If assistance
is required please contact Parker Industrial Gas Filtration and
Generation Customer Service, 4087 Walden Avenue, Lancaster,
NY 14086, 1-800-343-4048.
1.1 Description of Operation
PSG Series is a two-stage, Penney-type electrostatic precipitator
used for removal of submicronic hydrocarbon emissions of
smoke and other airborne contaminants. The two “stages”
consist of an ionizing section and a collecting section, combined
in one assembly as a unicell. Each ionizing section consists
of a series of (10 mil) wires charged to a high DC voltage and
centered between a like series of grounded plates. This high
voltage differential generates an intense electrostatic field where
airborne particles are “ionized,” i.e., positive polarity. Each
collecting section consists of a large number of parallel cell
plates, alternately charged at high DC voltage (the same polarity
as the ionizer but about half the voltage magnitude) and ground
potential, thus forming a magnetic field. Charged particles are
simultaneously repelled by the cell charged plates (smaller
dimensional plates) and attracted to cell ground plates (large
dimensional plates). The result being a highly efficient removal
of charged particulate from the airstream as it passes through
the electrostatic precipitator. The total current to both the ionizer
and collector cell circuits is below 5 milliamps which is non
lethal. Unicell components are usually preceded and/or followed
by mesh filters to assure even distribution of air, at low velocity.
Air movement is provided by a system blower located behind
the unicell components that exhausts cleaned air at a specified
cfm rate. More complex systems can include other conditioning
equipment.
1.2 System Definitions
PSG Series is designed for rigorous, often continuous, smoke
and particulate removal duty. The system includes mechanical pre
filters (as applicable), unicells (combination ionizer and collection
cell), power pack enclosures and pre/after filters. The PSG Series
has been tested to operate in accordance with national listing
standards of agencies such as Underwriters’ Laboratories (UL)
and ETL, with local approvals from selected cities as required.
PSG units are designed for installation in customer ducting where
other system components, including the blower, may be provided
by others. PSG systems can include blowers, skids and other
factory-assembled equipment, which arrives in the field ready for
installation.
1.3 Unit Nomenclature
PSG systems may include various combinations of features
connected in series in the direction of airflow. The PSG’s
configuration code is defined with a series of letters. Refer to
Figure 1. On “single-wide”, (the width of one module which is
one or two or three unicells placed in series) the access doors to
collecting components face the operator as air flows from left to
right. Opposite side access right to left is also available. “Double
wide” (the width of two modules placed side by side) have access
doors on both sides, each door accessing one module, left to
right, and right to left in one system. Air which flows through
one set of unicells will make a single cleaning “pass.” When an
application dictates, multiple passes can be placed in series in the
direction of airflow. A two-pass system is illustrated in Figure 2.

1.4 Description of Components
1.4.1 Power Packs
Each power pack converts 115 volt, single-phase AC power to
high voltage DC for one or two or three unicells (each with one ion-
izer and one collecting section). This combination of components
comprises a working “module.” Standard packs supply positive
DC voltage of 11.0 (nominal) KVDC to each ionizer and 5.5 KVDC
to each collection cell. Power packs with special ratings are sup-
plied on certain applications. Power packs are mounted in power
pack enclosures located on the module doors to the PSG.
