[0002] Electrolytic copper foil is a kind of electronic functional material with specific performance prepared by electrochemical deposition, and is usually produced by roll type continuous electrolysis method, which is to install back-shaped cathode roller and insoluble anode in electrolytic cell, the bottom of roller is immersed in electrolyte, after electrification, copper ions in solution are deposited on the surface of roller to form copper foil, then the copper foil is stripped, washed, dried and coiled, and the copper foil prepared in this process is called green foil.

[0003] A large amount of acid mist containing sulfuric acid-copper sulfate is generated in the process of green foil, most of which is from the precipitation of electrode surface bubbles in the process of electrodeposition, and part of which is from the volatilization of electrolytic production liquid itself.If the acid mist is not discharged in time and effectively, it will have many adverse effects, such as falling into the surface of copper foil to form black oxidation points, corroding production equipment, endangering personal health, polluting the environment, etc.Copper foil production enterprises usually use air extraction system to extract and discharge acid mist, but because the acid mist contains copper sulfate component, it will gather in the air extraction pipeline to form copper sulfate crystals, and after a long time of operation, the crystals in the air extraction pipeline will accumulate more and more thick until the pipeline is blocked, which seriously affects the rate of acid mist extraction.

[0004] Therefore, it is necessary to develop an electrolytic copper foil green foil machine acid mist absorption treatment device to solve the above problems. UTILITY MODEL CONTENT

[0043] Embodiment 2

[0044] Referring to Figures 2-3 , the acid mist absorption treatment device of the electrolytic copper foil precursor machine comprises an acid mist absorption tank 2, a water collecting tank 3 and a circulating pump 4. The acid mist absorption tank 2 is arranged above the electrolytic cell 1. The acid mist absorption tank 2 comprises first, second, third and fourth acid mist absorption pipelines which are in communication with each other. The first, second, third and fourth acid mist absorption pipelines are arranged on the side walls of the electrolytic cell 1 respectively. The first, second, third and fourth acid mist absorption pipelines are provided with air inlets 21 near the side walls of the electrolytic cell 1, for absorbing the acid mist escaping from the electrolytic cell 1. The acid mist absorption tank 2 is further provided with a plurality of water inlets 22 and air inlets 23. The air inlets 23 are arranged on the side walls away from the opening of the electrolytic cell 1. One end of each air inlet 23 is in communication with the acid mist absorption tank 2, and the other end is in communication with the water collecting tank 3. The acid mist absorption tank 2 is provided with an air outlet 26 which is in communication with the air inlets 23. One end of each water inlet 22 is in communication with the acid mist absorption tank 2, and the other end is in communication with the water collecting tank 3 through a first pipeline. The first pipeline is provided with the circulating pump 4 and a filter 5 which is arranged between the circulating pump 4 and the water inlets 22. The acid mist absorption tank 2 is in communication with a negative pressure suction mechanism through a pipeline, so as to maintain a negative pressure state in the acid mist absorption tank 2, and the acid mist escaping from the electrolytic cell 1 can be sucked into the acid mist absorption tank 2 in time. A spray pipe 24 is arranged in the acid mist absorption tank 2. The spray pipe 24 is in communication with the water inlets 22 and is arranged near the upper part of the acid mist absorption tank 2. A plurality of water mist nozzles 25 are arranged on the side wall of the spray pipe 24. The water collecting tank 3 is provided with a water supplementing pipe 31 for supplementing water into the water collecting tank 3. A drain pipe 32 is arranged on the lower end of the side wall of the water collecting tank 3. The drain pipe 32 is provided with a drain valve 33. The water collecting tank 3 is provided with an air inlet pipe 34 which is in communication with the air inlets 23 through a second pipeline. The lower end of the side wall of the water collecting tank 3 is provided with a water outlet pipe 35 which is in communication with the first pipeline. The upper end of the water collecting tank 3 is provided with an air outlet pipe 36 which is in communication with the inside of the water collecting tank 3 at one end and is in communication with an acid mist purification device at the other end.

[0045] When the acid mist absorption treatment device of the electrolytic copper foil born machine of the embodiment is used to absorb acid mist, the acid mist absorption tank 2 is kept in a negative pressure state, and the acid mist is sucked into the acid mist absorption tank 2. The water flows into the spray pipe 24 through the water inlet pipe 22 and is sprayed out through the water mist nozzle 25. The sprayed water mist absorbs the acid mist, and the water mist then enters the air duct 23, enters the air inlet pipe 34 through the second pipeline, and then enters the water collecting tank 3. Then, under the action of the circulating pump 4, the water enters the spray pipe 24 through the water outlet pipe 35, the first pipeline and the water inlet pipe 22, and is sprayed out through the water mist nozzle 25, so that the acid mist absorption work is continuously carried out.

In addition to the water flow or water mist, gas or air flow also enters the air inlet pipe. The gas or air flow entering the water collecting tank 3 through the air inlet pipe 34 contains acid mist that has not been absorbed by the water mist. The part of the gas or air flow containing acid mist is discharged through the air outlet pipe 36 and enters the subsequent acid mist purification device for further treatment.

[0046] After the water mist absorbs the acid mist, it plays a role in diluting the acid mist and reducing the concentration of copper sulfate, so that the copper sulfate crystals are not easy to precipitate. At the same time, the water mist gathers on the inner wall of the acid mist absorption tank 2 and the air duct 23 to keep the inner wall wet, so that it is difficult for copper sulfate crystals to form. In addition, the water mist gathers and condenses on the inner wall of the acid mist absorption tank 2 and the air duct 23 to form a water flow. The water flow flows down along the inner wall of the acid mist absorption tank 2 and the air duct 23 to timely take away the acid mist and the unprecipitated copper sulfate that falls on the inner wall, preventing them from precipitating and forming crystals on the inner wall. For the precipitated crystals, the water or water flow condensed on the inner wall of the pipe can dissolve them, and the dissolved copper sulfate is taken away by the water flow, thereby achieving cleaning of the acid mist absorption tank 2 and the air duct 23.

[0047] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
