Dust monitoring with ProSens on clean gas side - Case Study
An international mining company extracts minerals under ground for the fabrication of fertilizers. For the long term improvement and safety of the structure stability fi llings and binders (dry bulks) with defi ned recipes are injected locally into former mining cavities.
These materials are delivered above ground, stored in silos and afterwards transported in a closed-pipe pneumatic conveying system to storage silos below ground.
There the fillings and binders are mixed with a salt solution, pumped to the cavities and eventually harden. The silos used for the intermediate storage are under negative pressure for safety reasons. They are equipped with a silo vent fi lter (main fi lter) and a downstream security fi lter (secondary filter).
This assures the air purity according to legal regulations, which is measured constantly after the security fi lter. When a specifi ed limit value is reached, an alarm should be transmitted to the control room.
- Customer: Raw materials company (Germany)
- Product: Fillings and binders
- Material humidity: 2 mg/m3
- Installation place: Exhaust air pipe, clean gas side after security fi lter
- Function: Monitoring of exhaust air particulates
The ProSens was specially developed to carry out reliable dust measurement on clean sides after fi lters. The measuring device provides measurement values for dust concentration either as a trend signal or as absolute values (after calibration) for emission measurement. In the described application the ProSens measures exhaust air of underground storage silos on the clean side after safety fi lters.
This helps to comply with limit levels, given by law and to assure safe air quality underground.
- Dust measurement in large channel diameters
- Assurance of safe air quality below ground
- Compliance with legal requirements
