With the advance of environmental protection ultra-low emission policy, the steel industry is required to expand from organized emission to unorganized emission when carrying out emission. The organized discharge means that dust is regularly and intensively discharged through fixed discharge ports, and the unorganized discharge means that dust is randomly discharged into the air through the discharge ports which are not regular. Since there is no fixed vent for the unstructured discharge, contaminants (e.g., particulate matter, dust, etc.) can diffuse directly into the ambient air.
