The lime kiln dust collector mainly sucks in suspended particles in the atmosphere and uses principles such as attachment, capture, and impact to form a layer on the surface of the filter bag, thereby achieving the goal of purifying the air. The lime kiln dust collector uses a high-pressure fan to send the smoke discharged from the factory into the inlet, where an inlet cover (or pipe cover) is installed to prevent high-temperature and high-pressure smoke from directly entering the dust collector. After entering the dust collector, the flue gas first passes through the wet dehumidification device to remove the fine humidity in it, in order to prevent the subsequent pulse bag dust collector from getting damp.
