Truck and Train Dumpers

Train and truck unloaders create a great deal of dust due to the large mass of product that is disturbed at one time and the effect of impact on the receiving hopper. A large area such as this is difficult and costly to implement dust control on with methods of dust collection, such as baghouses and wet scrubbers, and also costly. Dry fog can be applied in manifold arrangements for belly dump, rollover and tipping unloaders, preventing escape of fugitive dust without the need for collection and disposal.



Larger DSN-12 nozzles are used to give a longer projection from the nozzle as well as a greater volume of fog, allowing the receiving bin to be filled with fog which prevents the escape of dust at both the tip and subsequent uprush of displaced air which carries fugitive dust. Fog nozzles are mounted in manifolds to be mounted along the top edge of the hopper, providing a blanket of fog which keeps the dust from escaping.



Traditional dust control in trainloaders uses scrubbers or baghouses. Due to the large volume of air needed to be extracted from the local area around the recieval bin, these dust collectors tend to be large in size, require high power motors, and need a lot of infrastructure and real estate for ducting, fans and stacks, and the collector itself. Fog systems only require an air and water supply at low pressure and relatively low volume, do not have to collect and dispose of the dust, and can easily be retrofitted to existing systems if required.
