Treatment of dispersed iron-bearing raw materials and modeling of the protection systems against air-pollution
Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that occur in the accident, as well as the modeling of the system of protection agains...

| description | Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that occur in the accident, as well as the modeling of the system of protection against air-pollution due to the cancellation of work the bag filter was carried out. Applying the model (Aloha software package) provides an overview of possible developments of events and zones of propagation of the precipitated particulate matter through the share of cadmium (Cd) in them. In the case of malfunction of filter system, emissions of particulate matter enormously exceed the permitted values. In the conditions of the simulated accident, particle velocity of flue gases was amounted E≈738mg/s or 2657g/h of dust. The propagation of the precipitated particulate matter in the lower layer of the atmosphere, downwind, given trough the share of Cd in them, is 100m from the source of pollution for the characteristic density of 5mg/m2×day and 140m for the characteristic density of 2mg/m2×day, in the stable state of the atmosphere, i.e. 870m and 1100m, respectively, in the neutral state of the atmosphere. |
