Abstract
The invention discloses a production process for ultrasonic dissolved copper in electrolytic copper foil production. A copper raw material is placed in a dissolved copper tank filled with sulfuric acid solution. The process is characterized by comprising the following steps of: providing oxygen for the dissolved copper tank through an air delivery pipe, and simultaneously starting an ultrasonic generator on the dissolved copper tank, wherein the ultrasonic waves generated by the ultrasonic generator enables the solution in the dissolved copper tank to vibrate and provides heat for the dissolved copper tank when the solution vibrates, so that the copper sulfate generated by reaction of the copper raw material and the sulfuric acid solution is quickly peeled from the surface of the copper raw material and dissolution of the copper raw material is achieved. The energy consumption is low, the energy is saved, the production cost is reduced, and the copper dissolution rate can be greatly improved.
Description
Technical field
The present invention relates to the production technique of molten copper, the production technique of the molten copper of ultrasonic wave during especially a kind of electrolytic copper foil is produced.
Background technology
Molten copper process is also referred to as the electrolytic solution preparation, is first procedure that electrolytic copper foil is produced, and purpose is that the copper material is dissolved into sulfate liquor, to supply with former paper tinsel production process.The chemical equation of molten copper process is as follows: Cu+1/2 O
2+ H
2SO
4=Cu
2++ SO
4 2-+ H
2O+221KJ
In the molten process for copper of current electrolysis Copper Foil, generally be to utilize steam to carry out molten copper for copper dissolving tank provides heat under the normal pressure, molten copper mode has these two kinds of the molten copper of high temperature (molten copper temperature is more than 75 ℃) and the molten copper of low temperature (molten copper temperature is below 65 ℃).The molten copper speed of the molten copper method of high temperature is fast, but energy consumption is big, and the molten copper method of low temperature energy consumption is little, but molten copper speed is low.
Summary of the invention
Technical problem to be solved by this invention is to provide the production technique of the molten copper of ultrasonic wave in a kind of electrolytic copper foil production.The present invention not only energy consumption is low, and can increase substantially molten copper speed.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows: the production technique of the molten copper of ultrasonic wave during a kind of electrolytic copper foil is produced, raw copper is placed the copper dissolving tank that sulphuric acid soln is housed, it is characterized in that: provide oxygen for copper dissolving tank by air delivery pipe, open the ultrasonic generator on the copper dissolving tank simultaneously, the ultrasonic wave that ultrasonic generator sends makes the solution vibration in the copper dissolving tank, and when making the solution vibration, ultrasonic wave provides heat for copper dissolving tank, thereby the copper sulfate that the reaction of raw copper and sulphuric acid soln is produced is peeled off rapidly from the raw copper surface, reaches the dissolving of raw copper.
In the production technique of the molten copper of ultrasonic wave, the ultrasonic power that described ultrasonic generator sends was controlled at 1000～1500w during aforesaid electrolytic copper foil was produced.
In the production technique of the molten copper of ultrasonic wave, the ultrasonic frequency that described ultrasonic generator sends was controlled at 20～100khz during aforesaid electrolytic copper foil was produced.
In the production technique of the molten copper of ultrasonic wave, the working temperature of described copper dissolving tank was 45～65 ℃ during aforesaid electrolytic copper foil was produced.
During producing, aforesaid electrolytic copper foil in the production technique of the molten copper of ultrasonic wave, adopts the thermopair control working temperature in the copper dissolving tank, in case too high water vapour and the acid gas of causing of solution temperature volatilizees too fast.
In the production technique of the molten copper of ultrasonic wave, adopt the liquid level of the liquidometer control solution in the copper dissolving tank during aforesaid electrolytic copper foil is produced, the assurance ultrasonic wave is handled copper-bath below liquid level.
In the production technique of the molten copper of ultrasonic wave, described ultrasonic generator was 2 ultrasonic generators that are symmetricly set on the copper dissolving tank during aforesaid electrolytic copper foil was produced.
Beneficial effect of the present invention: compared with prior art, the invention provides the molten process for copper of a kind of ultrasonic low temperature, it has utilized hyperacoustic mechanical effect and cavatition.Hyperacoustic mechanical effect role in molten copper is: the liquid particle high vibration that makes copper-bath, mass transfer, the diffusion of copper-bath have been quickened, thereby solution is played good stirring action, copper sulfate is peeled off rapidly from the copper surface, quickened the dissolving of raw copper; Cavitation effect of ultrasonic waves role in molten copper is: make that micro-bubble shakes in the copper-bath, enlarge, shrink and even collapse a series of dynamic processes, thereby the partial state of liquid changes a lot, produce high temperature, help improving the dissolution rate of raw copper.In addition, utilize hyperacoustic resonance energy further to improve molten copper speed.Simultaneously, adopt working temperature to be 45～65 ℃ and carry out molten copper, cause water vapour and acid gas volatilization too fast, also reduced energy consumption in case solution temperature is too high.Therefore, the present invention not only energy consumption is low, has saved the energy, has reduced production cost, and can increase substantially molten copper speed.
The present invention draws through experiment: energy consumption of the present invention is 50%～60% of the molten copper of common low temperature, 33%～36% of the molten copper of high temperature; Molten copper speed is 4～6 times of the molten copper of common low temperature, 2～3 times of the molten copper of high temperature.It is 0.1～0.12 ton that but the present invention is scaled standard coal with respect to 1 ton of save energy of the every molten copper of the molten copper of common low temperature; But being scaled standard coal with respect to 1 ton of save energy of the every molten copper of the molten copper of high temperature is 0.15～0.2 ton.
The present invention is further illustrated below in conjunction with embodiment, and embodiments of the present invention are not limited to following embodiment, and the various variations of making under the prerequisite that does not break away from aim of the present invention all belong within protection scope of the present invention.
