Problems solved by technology

Therefore, reducing the concentration of flying matter contained in the air discharged to the outside can reduce the flying matter discharged per unit time, but the total amount discharged continuously for a long time in the electroplating plant is still considerable

Embodiment 1

[0073] Such as figure 1 A schematic structural diagram of the electroplating equipment 100 in Embodiment 1 of the present invention is shown. The electroplating equipment 100 in this figure includes an electroplating tank 1 with an upper opening; an air curtain mechanism 2, which forces air circulation air to the upper opening 10 of the electroplating tank 1 in the horizontal direction, and substantially closes the electroplating tank 1 with the circulating air. The upper opening 10 is used to transport the scattered matter discharged from the upper opening 10 of the electroplating tank 1 with circulating air; The recovery liquid 31 absorbs the scattered substances contained in the circulating air into the recovery liquid 31 for recovery; the circulating air duct 4 connects the air curtain mechanism 2 and the spray tower 3, so that the circulating air flows between the air curtain mechanism 2 and the spray tower 3 circulation; the circulation fan 5 circulates the circulating ...

Embodiment 2

[0086] Figure 4In the electroplating equipment 200 shown, more than two air curtain mechanisms 2 arranged in parallel on each electroplating tank 1 are connected to the spray tower 3 . The electroplating equipment 200 (100 in the original) has the advantage of recovering flying substances from the circulating air circulated by two or more air curtain mechanisms 2 through one spray tower 3 , thereby reducing the cost of the spray tower 3 .

Embodiment 3

[0088] In the electroplating equipment 100, the spray tower 3 and the circulating air duct 4 may be integrally constructed. exist Figure 5 In the electroplating equipment 300 shown, the spray tower 3 and the circulating air duct 4 arranged along the electroplating tank 1 are integrated with each other. The circulation pipe 4 is shared with the spray tower 3 , the vertical part is arranged on both sides of the electroplating tank 1 , and the horizontal part is arranged under the electroplating tank 1 . The vertical part of the circulating air duct 4 sprays the recovery liquid 31 from the nozzle 32 to the inside, absorbs the scattered matter of the circulating air into the recovery liquid 31 and recovers it. The horizontal part of the circulating air duct 4 is provided with vertical walls 36 extending upwards and downwards, and the upper and lower ducts 35 that make the circulating air supply zigzag in the upward and downward directions are arranged between the adjacent vertic...

Abstract

The present invention relates to a treatment method for scattered substances in an electroplating factory and electroplating equipment for the treatment method, which can recover scattered substances of an electroplating solution contained in air without discharging the scattered substances of the electroplating solution outdoors, thereby preventing public hazards caused by the scattered substances. A method for treating scattered substances in an electroplate factory, which is a method for treating scattered substances in a plating solution (11) generated in a plating bath (1) in a building, in which an upper opening (10) of the plating bath (1) is closed by an air curtain (20) formed by circulating air blowing, the circulating air discharged after the air curtain (20) passes through the upper opening (10) is guided to a spray tower (3), a recovery liquid (31) is sprayed to the circulating air in the spray tower (3), scattered substances of the plating solution (11) are absorbed by the recovery liquid (31), the circulating air circulates between the spray tower (3) and the air curtain (20), and the scattered substances of the plating solution (11) are recovered by the recovery liquid (31) in the building.

Description

technical field [0001] The present invention relates to a treatment method and electroplating equipment for improving the environment by recovering scattered substances such as chromic acid generated in an electroplating bath without discharging them outdoors. Background technique [0002] In the electroplating process, harmful chromic acid flying substances are generated from the electroplating bath. In order to recover the scattered substances, a device has been developed that installs an air duct in the electroplating tank, sucks in the air containing the scattered substances at the opening, and sprays and separates the scattered substances with a spray tower (see Patent Document 1). [0003] Prior Art Documents, Patent Document 1 Japanese Utility Laid-Open No. Showa S52-132369. [0004] Patent Document 1 discloses an apparatus for recovering chromic acid spatter generated from an electroplating tank. This publication discloses that the chromic acid contained in the air...
