Abstract

The invention provides an on-line pelletizing device and method for precipitator dust. Before being collected through a cloth bag, the precipitator dust is subjected to pelletizing processing, so that the service life of the cloth bag and the service life of a keel are prolonged advantageously, secondary environment pollution in the precipitator dust transportation process is avoided, and the precipitator dust recovery utilization rate is increased. The on-line pelletizing device is characterized by comprising a blender; a feeding inlet of the blender is connected with a dust bin; the dust bin is provided with an on-line connecting interface connected with a steel smelting dust remover; and a discharging outlet of the blender is connected with a pelletizer.

Description

technical field [0001] The invention relates to the dust removal ash treatment technology in the iron and steel smelting dust removal system, in particular to an online pelletizing device and method for the dust removal ash. By pelletizing the dust removal ash before the bag is collected, it is beneficial to prolong the service life of the bag and the keel , to avoid the secondary pollution of the environment during the transportation of dust removal dust, and to improve the recycling rate of dust removal dust. Background technique [0002] Many links in the iron and steel smelting process, such as sintering, ironmaking, and steelmaking, will produce a large amount of dust. Because it contains a variety of valuable metal elements, such as stainless steel smelting dust containing iron, chromium, nickel, molybdenum and other elements, electric furnace dust contains a large amount of elements such as lead, zinc, potassium, sodium, etc., if the dust removal dust can be directly ...
