Plain Water Dust Suppression System

The  dust suppression system in the coal handling plant is a wet dust suppression system. Wetting Agents are chemicals that are added to water to improve the rate at which spray droplets wet dust particles.

This system consists of three main parts.

Water Pump, Water Tank, etc  

 Spray headers with pipe lines & pumping system.

Control units with electrical systems.

 Spray header with pipe lines pumping system includes solution pumps, isolating valves, spray nozzles, and pipe lines. The solution pumps are used to supply pressurized water to spray headers. The required quantities of nozzles are used to spray water. 

 CONTROL UNITS WITH ELECTRICAL SYSTEMS consists of sensing units, control panels. Coal flow is sense by sensor. The control panels are consisting of various relays and transformer.

Operation of DS System

Auto control or manual control governs the system. It has to be insured that main tank is filled with water. The water is pumped by feed water pump from main tank to feed water tank.   the system in recalculation.  The sensing system for controlling spray at proper header ensures spraying solution if conveyor is running with coal. And will not allow spraying solution if conveyors are running empty, the solenoid valve headers are energized if conveyor is running with coal. If all or some of the solenoid valves are not energized the system will realize pressure through pressure relief valve, which protects the system. A solenoid valve is provided with bypass line, which operates when none of the spray header solenoid valves are operative.

Stock Pile Sprinklers

Uses: stockpiles and haulways

Sprinkling system is used for dust suppression of stockpile.  Water is sprayed on the stockpiles to keep the coal damped and prevent dust to flying around . Sprinklers Irrigation systems is used to control dust on outdoor stockpiles, but when the stockpiles are excavated, dust will arise as the drier material in the pile is exposed and moved around.   An sprinkler  system uses a lot more water than a fogging system – almost 10 times , sprinkling system is chosen after a lot of considerable planning and forethought.

One Sprinkler  can move around its axis and can throw the water even up 20-40 m away.

FOG CANON 

Fog canon for Dust Suppresion

We in association with our team of engineers and designers developed a cutting age technology for Fog Canon and offers different types of Fog Canon. Fog cannon can operates with different principles and mechanisms.  One of types  is purely mechanically driven system with electrical motor inputs, here in also we can offer different  type  of system with different basic principles for operation of the fog canon. while, mechanical one can be prone to maintenance during it life time, we also offer other cutting age technology, which is trouble free system, with bare occasional maintenance.

Fog canon is widely used in India and overseas for   suppression of flying dust on various application, It is a rugged and very efficient system.  Unlike other types of dust suppression, it efficiency is very high. In some of applications only and only Fog canon is very successful, particularly when it is an open area.

Fog canon is normally mounted  on a trolley and it can be  moved from one location to other location as it is on wheels.  It is namely used for suppression of the flying dust very efficiently from a distance and also covers a very wide area. It throws the mist at a distance  It is widely used in  irrigation and industrial purpose.  

In industrial application, most widely used application is Stock yard Area, Dirty mines,  Tripper/Truck unloading in mines and ground hopper, wagon trippers, Reclaimer hoppers,waste   water evaporation, any locations where dust is flying and open too. In open area, only and only Fog canon is used widely, as other methods of catching dust  fails poorly on this fronts.

In industrial applications, where overuse of water can be issue, at such locations, Fog canon will be more useful and are more suitable for dust suppression than sprinklers in general.

In agriculture, normally it is used for irrigation purpose. Even during building breakings, ship breakings etc it is also used widely.

We offer various type of Fog canon, and  every Fog canon is individually designed and manufactured as per client requirement and applications,

Fog canon can be fixed type and rotating type.

In fixed type, Fog canon will suppress the dust in single direction, while in Rotating type, it can rotate and suppress the dust in different directions. Fog canon rotate around on its axis by 90 deg, 180 deg or up to 330 Deg. as per client requirement,  we   individually design and manufacture the fog canon.

Rotation of Fog canon helps in suppression of  dust in almost all the direction around its axis inside the diametrical circle falling in its range.

We  supply Fog canon for a throw away range up to, 35m, 50m, 60m, 70m, and 100m.150m,200m

Dry Fog  System 

We supply dry fog type dust suppression system for all the application. Dry Fog Dust control Systems have been in operation worldwide. It  make dual fluid (air and water) atomizing nozzles control virtually all breathable and fugitive dust  

THEORY AND APPLICATION :: 

     The "Dry Fog" Dust Control System works on the principle of agglomeration. The Dust particles released from a Material Handling/Processing Plant which become air borne are made to pass through a blanket of extremely fine Fog. The dust particles and the Micronics size Fog droplets collide and adhere to each other, thus increasing their mass. After a series of such collisions, even the breathable and fugitive dust ranging from 1 to 800 microns mass agglomerates to become heavier enough to settle. The lower capital, operating and maintenance cost compared to De-dusting Bag House System made it popular in the industries. Easy installation in existing plants. In most cases, the system can be installed while the plant operates at full capacity. No major plant modifications are required for installation of the system. Water addition to the process is as low as 0.1% of the weight of the material being handled. No requirement of Chemical.

Dry fog for type dust suppression system is widely used at ground hopper, transfer towers, coal handling plants etc.
