Acid mist recovery system device

The utility model relates to accessory equipment of electrolytic deposition equipment in the field of a chemical technology, in particular to an acid mist recovery system device. The acid mist recovery system device comprises a cathode frame and an anode frame which are arranged in an electrodeposition cell, and also comprises an acid mist absorbing tower and a circulating groove, wherein an osmotic membrane is arranged between the cathode frame and the anode frame; the cathode frame and the anode frame are fixedly connected through a threaded rod; an acid mist discharge opening is formed in the anode frame; ventilation channels are formed on the electrodeposition cell; each ventilation channel is provided with a small hole corresponding to the acid mist discharge opening in the anode frame; a draft fan is connected with the ventilation channels through pipelines; the acid mist absorbing tower is connected with the air draft fan and the circulating groove respectively. The acid mist recovery system device changes the severe environment caused by the situation that acid mist generated during an electrodeposition process in an old electrodeposition device is discharged directly and unsystematically. Ventilation equipment adopts negative-pressure type air drafting, so that resources are saved. The phenomenon that liquid formed on a gas-collecting hood drips on a copper row or a copper rod and corrodes the copper to affect the quality of the product nickel, which is caused by adopting the gas-collecting hood is avoided.
