Exhaust Emission and Pollution Control Systems
Technological requirements, legislative pressures, and last but not least a growing
environmental concern by the population at large have led to substantial improvements in
particle separation from gases during the past few years.
Correctly engineered and well-maintained emission control systems have a proven record of
performance for fine particle separation.
We at RAYGM offers customized emission control systems for our customer
needs, truly engineered to meet legislative requirements with lowest possible CAPEX + OPEX.
Our Customised Emission Control Products include
1. Cyclone Separators
2. Bag Filter (Bag House)
3. Wet and Dry Scrubbers.
1. High Efficiency Cyclones.
Cyclones provide a relatively low-cost method of removing particulate matter from exhaust
gas streams. Cyclones are somewhat more complicated in design than simple gravity settling
systems, and their removal efficiency is accordingly much better than that of settling
chambers. Cyclones are often installed as pre-cleaners before these more effective devices.
The range of particle sizes collected in a cyclone is dependent upon the overall
diameter and relative dimensions of the device. Various refinements such as the use of
skimmers, turning vanes, improve efficiency. Stacking cyclones in series or in parallel can
provide further alternatives for improving overall collection efficiency.

2. High Efficiency Bag Filter (Bag House)
Fibrous filter media have acquired a firm place in today’s separation technology. They are
the medium and technique of choice when efficient separation is required.
Dust laden air is drawn in the bag house and passed through filter media. The initial
filtering phase takes place within the interior of the medium and then relocated to the
surface. Thus, the filter cake deposited on the surface becomes the actual filter medium,
which can reach separation efficiencies of more than 99.9 %. As the layer of dust increases
the filter resistance rises. The Cleaned air exits through exhaust duct.
Dust collectors are supplied with compressed air headers, Solenoid valves and timers. With
the help of timers compressed air is blown in the bags which draws surrounding air with
Ventury effect in the bags giving reverse blow which disengages the dust on the filter media
and gets collected at the bottom of the Bag filter, regularly discharged through and Rotary
Valve or Screw conveyor.

3. SCRUBBERS
As the name scrubber implies, wet collectors or wet scrubbers are devices that use a liquid for removing particles or polluted gases from an exhaust gas stream. Water sprays can be injected into the gas stream; gas can be forced to pass through sheets or films of liquid; or, the gas can move through beds of plastic spheres covered with liquid. Each of these techniques can effectively remove particulate matter from process exhaust gases. They can also effectively remove gases such as particulate matters, HCl, SO2 etc.

- Dynamic Mechanically assisted scrubbers.
- High efficiency adjustable venturi scrubber
- Multi-venturi scrubber
- Packed towers for gas absorption, odour control.
- Self-Priming Venturi Scrubbers.
- Volatile Organics Condensing and Coalescing Scrubber.
- Aerodynamic Dry Scrubbers.
RAYGM CYCLO-VANE SPRAY SCRUBBER
Scrubbing liquid is introduced into the scrubber as a spray directed down over a circular
“SwirlScrub Section” arrangement. As the liquid drains through the vanes, it creates
curtains of scrubbing liquid. Dust laden gas enters the scrubber tangentially and collides
with the curtains initiating particle agglomeration. The coarser particles produced are
washed down to the slurry outlet.
Due to cyclonic action of the saturated gas stream as it spins upward forces the
agglomerated particles to fall out of suspension. The coarser droplets impinge on the mist
eliminator vanes and the finer droplets are forced to drop out of suspension by
gravitational and centrifugal forces acting on the gas stream as it exits through the top.
RAYGM DYNAMIC SPRAY SCRUBBER
This is combination of Cyclonic Scrubber and Centrifugal Fan. Dust laden gas enters
the
lower chamber of the Cyclonic Scrubber tangentially, imparting a cyclonic action to
the
stream. Coarse particles are removed by a combination of centrifugal and
gravitational
forces.
The gas stream containing the remaining fine dust is drawn into an adjacent chamber
containing a wet- ted fan. Atomized scrubbing liquid is sprayed into the eye of the
fan,
further reducing droplet size. These droplets encapsulate the fine dust particles,
thus
enhancing agglomeration.
The gas stream then flows into the upper chamber tangentially at high velocity. The
wet
agglomerated particles are forced by cyclonic action against the chamber walls and
drain
down to the internal discharge cone. The gas stream, free of liquid droplets, spins
out
through an outlet atop the scrubber.
RAYGM VENTURI SCRUBBER
Another popular design from CorroComp is the Venturi scrubber. Venturis are used to
collect both particulate and gaseous pollutants, but they are more effective in
removing particles than gaseous pollutants.
With Venturi scrubbers, the dirty gas entering a scrubber is forced at high velocity
through a Venturi where it collides with scrubbing water. The tiny water droplets
capture particles through impaction and diffusion. The mist eliminator for a Venturi
scrubber is often a separate device called a cyclonic separator or droplet
separator.
The dirty water is then removed in the cyclonic separator and discharged into a
recycle tank. Some of the liquid is continuously purged to limit the solids
concentration and allow recirculation back to the Venturi section.
RAYGM PACKED SCRUBBER /ABSORPTION TOWER
Whether horizontal or vertical, packed-bed wet Scrubbers provide a reliable and
practical means of removing acidic and caustic mists and gases from corrosive
exhaust streams, with maximum efficiency and minimum pressure loss.
Pollutant laden gases enter at the bottom of the packed tower and rise upward,
contacting the scrubbing liquid draining down through the packed column. Since the
pollutant concentration decreases as the gas rises, there is constantly fresher
solvent available for contact, resulting in an efficient removal of contaminants.
Finally, the fine moisture droplets, still suspended in the cleaned gas stream, are
removed by a mist eliminator.
Scrub liquid from the eliminator is collected in an integral reservoir and recycled
to the tower. Makeup liquid is constantly introduced, and reagent is added on demand
using a dosing pump controlled by a pH monitor.
SELF PRIMING SCRUBBERS
Self-Priming Ventury Scrubbers are designed to remove soluble gases and particulate by inducing a gas flow using high pressure liquid focused into a Ventury throat, which eliminates the need for a separate exhaust fan or blower to transport the contaminated gas stream to the Ventury scrubber. Design incorporates a high-pressure liquid spray for maximum entrainment and scrubbing efficiency, and is the optimal choice where heavy contaminant loads, and corrosive conditions are present with less air present. This provides excellent removal capacities for the reactor systems which needs continuous venting. Like Acid Hydrolysis etc.
