The present invention discloses a device for inductively suppressing acid mist from electrowinning. The device comprises a polar plate. A first isolation net and a second isolation net are respectively provided at two sides of the polar plate. Gaps are left between the first and second isolation nets and the two sides of the polar plate respectively. A first isolation piece and a second isolation piece are respectively provided to two sides of a top of the polar plate and are respectively located above the first and second isolation nets. The present invention also discloses a process for inductively suppressing acid mist from electrowinning by using the above device. The acid mist suppressing device and process of the present invention can prevent formation of acid mist during an electrowinning process so that pollution of acid mist can be eliminated and clean production can be realized.
