Our unit is aluminum smelting enterprise, mainly producing aluminum ingots. The unit adopts wet dedusting equipment, and the packing tower explodes!
Aluminum chemical nature is lively, is a kind of metal dust explosion, explosion limit concentration of 30g/m3 1.24Mpa, the maximum explosion pressure, the maximum pressure rise rate of 41.5Mpa/s, the explosion index 41.5Mpa.m/s, risk rating St1.
The molten aluminum fume reacts with water to produce a large amount of heat and H2. The explosion occurs because the process design does not take into account this aspect and is poor in liquid spraying. This is only preliminary estimate. Please provide the parameters of flue gas inlet tower temperature, tower temperature, spray water quantity and temperature of inlet and outlet water for further judgment.
In the process of heating aluminum, when the temperature rises, the molten aluminum will produce tiny particles of atomic aluminum.
