Environmental Engineering & Industrial Pollution Control system now has become an important role in the Industry. During past years, conventional spraying system used for dust suppression system in Industrial air pollution control system. We have observed a few problems raised during operation of the conventional spraying system to control the dust of various characters during the last years period. Industrial raw material contents certain percentage of dust particles. Basically the breathable and fugitive dust particle of sizes from 1 – 800 microns, creates air pollution. Basically, the water particles of conventional water spraying dust suppression system can not agglomerate with fugitive fine dust particles ranges from 10 – 40 microns, Hence, modern environmental technology fine dust particles to control industrial air pollution to meet the norms of Pollution Control Board.
The system utilizes a high pressure SS Nozzle9SS-316), which produces fog by creating ultra fine droplet particles. Only water passing through inner chamber of the Nozzleat about-180-110Kg/cm2 pressure, which generates fine water droplets like the fog particles. Moisture contents with the fog droplet particles are lesser than normal mist type water nozzle and with in 0.5%.
PRINCIPLE OF SYSTEM
Fine water particle agglomerates the air borne dust particles, generated during conveying of material through conveyers, dumper unloading, heavy air movement or any other reasons. The dust particle becomes heavy and fall down to the original stream of material flow.
To achieve better performance of dust controlling system, it requires
a) Better agglomeration and strong collision between dust and water particles. b)The respirable dust particles are very fine of dia 1 – 20 microns. The fine dust particle can also collide with approx. same sizes of water droplets, which can also be generated with this fogging system.
c) Generation of fine fog water particles should be more than that pf dust generation at the application zone.
d) Fog particles have to contain in the dust generation zone. Hence, to achieve
Best performance, we have to enclose the generated dust at the application point properly to make it able to agglomerate properly.
We describe here with how to achieve agglomeration. Consider a water droplet about to impinge on the dust particle or a dust particle about to impinge on the water droplet as shown in the drawing. If the droplet diameter is greater than the dust particle, it simply follows the air stream lines around a droplet, a little or no contact occurs. In fact, it is difficult to impact between a micron size dust particles with a comparatively bigger size water particle as because the dust particle is not able to penetrate the internal air stream separator, simply follows the air stream line. On the other hand contact occurs between comparatively same sizes of dust and Water particles.
DUST SOLLUTION SYSTEM has developed a team with the experienced engineers, who have been working in the field of industrial air pollution control system since last few years. They have succeeded and got the best performance with their design, engineering, equipments and execution of various type Dust Suppression System in various applications. Specially designed nozzles are used to produce different sizes of fog particles.
The fog creates an envelop around the dust generating source and prevents the dust particles to become airborne. The internal converge section of nozzle accelerates the water stream of high velocity which generates fine fog particles.
SALIENT FEATURES:
a) Dust generation prevented at source.
b) Moisture addition is lesser than normal mist spray system at the rang of approx. with in 0.3%.
c) Dust nuisance tendency becomes nominal at transfer points.
d) No such adverse effect like mist spray system on the material handled. Material handling equipments like conveyors, screen, crusher, chutes, hoppers, feeders have no jamming problems, hence they do not clog/chock.
e) Operation cost is very nominal.
f) Easy to install, coverage area is very negligible.
