DUST SUPPRESSION

.hmc. Dry Fog TRUCK UNLOADING HOPPER DS system Operates with compressed air & water synchronized through a twin port nozzle atomizing water into a mist of microscopic particles as small as one micron.

PRINCIPLE OF OPERATION

The pump & compressor is to be activated manually (optional auto system if required) spray will activate automatically once the unloading of truck starts in the hopper.

The TUH DFDS Spraying actuation shall be controlled from operators cabin by pushing the LPBS switch to energize the normally closed Air & Water solenoid valve (Automation through sensor – optional).

The Spraying will be started / stopped through Solenoid Valve mounted on the Solenoid Boxes for each header.

Specific solenoid valves will get energized based on the truck movement and will get de‐energized through a pre‐set timer (adjustable).

The system shall be suitably interlocked by solenoid box with the truck unloading mechanism so that the spraying time should be throughout the complete operation of unloading. Total suppression system shall act in such a way that the water curtain shall cover the entire periphery of the hopper.

The Twin port Fogging type DFDS spray nozzle fitted on the entrance of the receiving pit area will spray to moisten the top layer of the trucks.

Further in order to form a water curtain around the entire periphery specially designed twin port atomizing nozzle shall be installed & activated at the same time with an air compressor & water pump (Nozzle discharge Air ‐3.5 CFM at 5 Bar, & Water‐0.3 lpm at 1 bar pressure).

Dust generating points will be properly placed with twin spray headers and DFDS nozzles which produce Fine Fog. The Air borne dust oncoming in contact with the fine fog type water particle, which becomes heavy and settle down with the original material flow.
