Definitions
- oxygen bubbles are generated on the surfaces of insoluble anodes that ascend towards the surface of the electrolyte. It is important to note that in this ascent the bubbles not only grow in size and increase their speed, but also capture water and sulfuric acid vapors from the electrolyte, which are incorporated into each bubble.
- the bubbles In the case of cells equipped with Electrolyte Aeration System, similar to that occurs with the air bubbles diffused from their bottoms, immediately before reaching the surface of the electrolyte, the bubbles contain a mixture of gases (oxygen and air) and vapors ( water and sulfuric acid).
- the Acid Mist constitutes a severe risk of occupational health and hygiene, because its limit concentration in the environment is regulated by the corresponding legislation; It also causes multiple well-known operational inconveniences, such as: corrosion of equipment and inlays of CuSO * crystals, current leaks and short circuits, among others. Therefore, it is mandatory to effectively control the Acid Mist.
- Nebiina Acida which for the purpose of this request we consider as formed by 2 phases, namely
- a gas phase consisting of a) permanent gases: oxygen from the electrolytic process and oxygen and nitrogen from the bubbling air and air infiltrated to the soil from the ship's environment.
- a liquid phase disperses in the gas phase as very small drops, due to the projection of electrolyte particles by collapse of the liquid film surrounding the surface of the bubbles when they reach the surface of the electrolyte.
- vapors are defined as any component of a gas phase that is condensed by simple cooling at temperatures slightly below ambient and atmospheric pressure; and by permanent gases, to any gaseous component that requires temperatures well below C * C and pressures above atmospheric to condense or liquefy them.
- Acid Mist as indicated above, that is, simply the mixture of contaminated permanent gases (oxygen and nitrogen) and water vapor, with electrolyte drops in suspension and sulfuric acid vapors, being The latter two hazardous pollutants in the work environment.
- the cells when the cells are uncovered, they discharge the confined volume of accumulated NebSna Acid directly to the work environment, and in addition, the electrolyte exposed with the energized cell continues to emit acid vapors and electrolyte drops without control to the work environment of the Ship. Due to the above, the work environment in the vicinity of the cells in harvest, exceeds punctually - and by far - the maximum regulated limits for the concentration of harmful substances to protect occupational health and hygiene, while the crops last.
- the abatement that is, the treatment of removal and fixation of the contaminants of the present invention, unlike the current art, is done with a minimum of dilution, that is, with minimal infiltration of air from the Ship to the cell, it reaiiza the closest to the electrolytic cells where they are generated, that is, without duel networks, and immediately recover the useful and valuable elements of the Acid Mist, namely water, acid and copper, You are immediately reused by recirculating them to the process.
- the covers described in the aforementioned Patent Application that is, non-porous, waterproof and thermal insulating covers, equipped with flexible seals allow an air infiltration flow of 10% and 100%, with respect to the flow of gases generated by e! process in each cell, which represents a maximum infiltration equivalent to once the flow of gases and vapors generated in each DCda by its operation, which is sufficient not only for the extraction of the Acid Mist of the cell without causing polluting emission to the work area, and due to the low flow, it also allows the efficient operation of the Pollutant Recipient Recovery System in the vicinity of the same cement in an efficient way and with very low energy requirement, such as It is proposed in the present invention.
