One end of the air suction pipe 25 is connected to one end of the top pipe 7. An activated carbon adsorption filter element 24 is installed inside the air inlet pipe 23.

[0020] In this embodiment, the high-copper-content acidic etching mother liquor discharged after etching is stored inside the etching solution storage tank 2. The acidic etching solution inside the etching solution storage tank 2 can be pumped into the electrolytic cell 3 through the first conveying mechanism 9. Excess copper in the acidic etching mother liquor is extracted by electrolysis. Then, the electrolyzed etching solution is transported into the mixing tank 4 through the second conveying mechanism 10. Acidic etching regenerator is added into the mixing tank 4 through the acidic etching regenerator hopper 11. After mixing evenly, the regenerated acidic etching solution is returned to the etching production line for reuse.

[0022] In this embodiment, when the solution is conveyed through the first conveying mechanism 9 and the second conveying mechanism 10, the acid-base magnetic pump 19 works to absorb the solution through the feed pipe 20 and discharge the solution through the discharge pipe 21.

During the absorption process, the gas will be adsorbed and purified by the activated carbon adsorption filter 24 inside the air inlet pipe 23.

[0025] In practical use, this utility model provides an acidic etching solution regeneration and reuse device with a protective structure. It recovers the high-copper-content acidic etching mother liquor discharged after etching and stores it inside the etching solution storage tank 2. The acidic etching solution inside the storage tank 2 is pumped to the electrolytic cell 3 via the first conveying mechanism 9. Excess copper in the acidic etching mother liquor is extracted through electrolysis. Then, the electrolyzed etching solution is transported to the stirring tank 4 via the second conveying mechanism 10. Acidic etching regenerator is added to the stirring tank 4 through the acidic etching regenerator hopper 11. The addition of the acidic etching regenerator to the acidic etching mother liquor activates the motor 15, which drives the rotating rod 16 and the stirring mechanism. Leaf 17 rotates to mix the solution evenly. The resulting regenerated acidic etching solution can be returned to the etching production line for reuse. The entire recycling device is protected inside the protective cover 5 during use to prevent some gases from spreading to the outside environment. The induced draft fan 22 inside the top box 8 can absorb the air above the inner side of the protective cover 5 through the suction pipe 25, the top pipe 7, and several air inlet pipes 26, which can absorb some of the gases generated during the recycling process. During the absorption process, the gas will be adsorbed and purified by the activated carbon adsorption filter element 24 inside the air inlet pipe 23, thereby reducing environmental pollution and providing good protection.
