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 for type dust suppression sysytem is widely used at ground hopper, trasfer towers, coalhandling plants etc.
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.
