Thread: Wet Vacuum Conveying

  1. #1
    Lou Bruno Guest
    We have an application for reclaiming arsenic trioxide ESP dust stored in underground bunkers. The dust has been stored for up to 50 years and the total stored quantity is 260,000 short tons. The dust was stored in various underground stopes and chambers via pneumatic conveyor. We know that groundwater has seeped into the chambers and stopes over the years and the material may be wet or dry, compacted or fluffy. It is hazardous to humans.

    Our idea is to reclaim via a remote controlled reclaiming system similar to that used for unloading bulk powder from ships. However, rather than using high speed vertical or inclined screws or pneumatic conveyors, we believe that a wet vacuum conveying system may be the best way to reclaim the product. Dry pneumatic conveying or high speed screws would not work for the damp product.

    We would appreciate information from vendors selling this type of wet vacuum system.

    Looking at your application, it looks like the powder (arsenic trioxide) will not have a consistent physical state. In some instances it could be compact, wet or just like dust. In my opinion, without knowing the requirements in terms of throughput and other reclaiming process parameters, you need to condition the material to one state.
    If a slurry is created, than wet vacuum can be used. Without some sort of operation of this kind, the delivery arrangement will be complex and probably difficult to maintain.

    We, specialize in the development of customized manufacturing equipment systems. Powder handling and conditioning is an area within our expertise.
