SDS SERIES™ DUST SUPPRESSION SYSTEM
Sun Combustion, Inc. has designed and manufactured liquid atomizing systems to resolve many of industry's production and pollution control problems since the company was started in 1988. Whether
the application is combustion, dust suppression, evaporative cooling or
conditioning of hot gases, re-moisturizing
of paper, humidification of production areas, quenching of steel from
roller mills, or the injection of chemicals and liquids, Sun
Combustion, Inc.’s liquid atomizing systems are in
continuous 24-hour day operation
in
numerous plants
worldwide. Sun Combustion, Inc.’s SDS Series™ Dust Suppression Systems control virtually all types of less than 5- micron (as small as 0.1-3 microns) breathable dust particles as well as larger size, up to 600 microns, fugitive dust particles. Control is accomplished through agglomeration of produced liquid droplets equal to or close to the size of the dust particles. These dust particles may include silica sand, dried clay, dry sand, limestone, aggregate, road stone, phosphate, coal, quartz, fiberglass, processed powders and many others. The SDS Series™ Dust Suppression System suppresses visible emissions from primary and secondary crushing, screening, transfer and loading-unloading facilities such as hoppers, feeders, bins, docks, silos, terminals and vehicles.
THEORY
AND APPLICATION
Basic research in the development of the SDS Series™ Dust Suppression System showed that if a sufficient number of liquid droplets of approximately the same size as the dust particles could be produced, in other words a fine dense fog, the probability of collision between the two would be extremely high. It was also determined that if the droplet size exceeded the size of the dust particle, there was little possibility of impact between the two and that the desired precipitation effect would not be realized because the dust particle would move around the liquid droplet. A device for generating such a dense fog of extremely fine droplets to envelop and bring down the dust particles at their source is the Sun Combustion, Inc. liquid atomizing nozzle working in a dust suppression system. By controlling atomizing air pressure, liquid atomization quality can be varied from a coarse 200 to 600 microns to an ultra-fine fog of 1-10 microns.
LIQUID
ATOMIZING NOZZLE The Sun Combustion, Inc.’s liquid atomizing nozzle is an air driven acoustic oscillator for atomizing liquids. By passing the liquid to be atomized through a field of high frequency sound waves it is vigorously shattered into very fine droplets. Air is accelerated beyond the speed of sound through a convergent / divergent orifice and then reflected back by a resonator cavity to complement and amplify the primary shock wave. Any liquid capable of being delivered to the high frequency sound wave zone will be atomized. Air, bypassing the resonator cavity, carries the atomized liquid droplets downstream in a soft, low velocity spray. Large orifices and low pressure virtually eliminate wear and prevent deterioration of the quality of atomization while greatly extending useful nozzle life. The greatest advantage of Sun Combustion, Inc.’s liquid atomizing nozzle is its ability to provide various size liquid droplets with consistent atomization quality over a wide liquid flow range.
Although
the SDS Series™ Dust Suppression System usually relies on water for the agglomeration
of dust particles, it is not limited in its functions by freezing
weather. There is a critical freezing mass for water droplets
below which the water will not freeze and above which
it will. That critical mass is approximately the equivalent
of a 20-micron diameter droplet. Sun Combustion, Inc.’s liquid atomizing
nozzles can produce droplets in the 1 to 20 micron range so
that the SDS Series™ Dust Suppression System continues to operate normally even
in sub-freezing temperatures. A special type of thermal insulation and / or heat
tracing, combined
with a post liquid purge system for the removal of all water
from the water supply lines and headers on shutdown, helps to alleviate the
problem of water transport to the liquid atomizing nozzles.
If water droplets, produced by the liquid atomizing nozzles, are allowed to
agglomerate on surfaces, freezing will take place but if the system
is properly installed and maintained there will be no interruption
in the operation of the SDS Series™ Dust Suppression System. ADVANTAGES The initial cost, operation and maintenance cost of a SDS Series™ Dust Suppression System are much lower than a ventilation type control system. In contrast to the use of large ducts and related equipment, the SDS Series™ Dust Suppression System operates with small diameter pipe and tubing, operates on as little as (5) percent of the total energy of conventional systems and can be installed for as little as 40% of the installation cost of a conventional ventilation / bag filter type system. The SDS Series™ Dust Suppression System offers these benefits and advantages:
