物等の形態で存在する水銀やカドミウム。Figure 1 is a flow sheet diagram showing the flow of dust generated from dust control equipment such as an air dust collector. The ash is first melted in an electric melting furnace 1, and heavy metals such as chromium and copper contained in the ash are fixed in the slag, and dioxins are melted at high temperatures and decomposed. On the other hand, the exhaust gas discharged from the electric melting furnace 1 is sent to a dry or wet exhaust gas treatment device 2, where mercury and cadmium, which are partially transferred into the exhaust gas by volatilization or scattering and exist in the form of soluble chlorides, etc. are removed.
鉛、亜鉛などの低沸点重金属類の有害物質がこの排ガス
処理装置２により効率よ（高ｍ度に回収される。したが
って、排ガス処理装置２からは無害な処理ガスだけが排
出される。Harmful substances such as low-boiling heavy metals such as lead and zinc are efficiently recovered by the exhaust gas treatment device 2. Therefore, only harmless treated gas is discharged from the exhaust gas treatment device 2.
