Description
Technical Field
The invention relates to the technical field of degreasing by using electroplating degreasing water, in particular to electroplating degreasing water degreasing equipment and a process flow.
Background
Electroplating cleaning waste water, it is the piece of plating waste water of discharging in the washing tank cleaning process, do not include and wash terrace and container and run, emit, drip, waste water and waste liquid such as hourglass, it is decorated metal and non-metallic surface to electroplate to utilize the method of electrochemistry, the protection reaches a process that obtains some new properties, for guaranteeing the quality of electroplating product, make metal coating have level and smooth good outward appearance and firmly combine with the base member, must plate a thorough sanitization of dirt on the surface before plating, and plate a surface attachment liquid sanitization after plating, therefore, a large amount of waste water must be discharged to general electroplating production process, electroplating waste water has some differences according to electroplating process's difference, wherein main pollutant has: various heavy metal ions: chromium, copper, nickel, lead, aluminum, gold, etc. are common; acid and alkali substances: such as sulfuric acid, hydrochloric acid, sodium hydroxide, sodium carbonate, nitric acid, etc.; toxic substances: cyanide various organics: the main components of the electroplating solution are metal salts and complexing agents, including sulfates, chlorides, fluoborates and the like of various metals, as well as cyanides, ammonium chloride, nitrilotriacetic acid, pyrophosphates, organic phosphonic acids and the like, and in addition, certain organic compounds, such as coumarin, butynediol, organic phosphonic acid and the like, which are used as leveling agents, are often added into the plating solution to improve the plating layer property, Thiourea, saccharin, vanillin, benzalacetone, p-toluenesulfonamide, benzenesulfonic acid and the like are used as brightening agents, so the rinsing wastewater of the plated part contains a small amount of organic matters besides heavy metal ions, the discharge amount of the rinsing wastewater and the type and concentration of the heavy metal ions are changed along with various factors such as the physical shape of the plated part, the formula of electroplating solution, the rinsing method, the electroplating operation management level and the like, particularly, the rinsing process has great influence on the concentration of the heavy metal in the wastewater, and the recovery of resources and the treatment effect of the wastewater are directly influenced.
When a workpiece is cleaned by a degreasing process before coating, a large amount of oil stains can be cleaned, the oil stains are from front-stage processes such as storage, transportation and rust prevention, and emulsified oil such as machining stamping and the like, the oil stains can be timely removed from a cleaning solution, so that the cleaning quality can be improved, the stock solution is prevented from deteriorating, the replacement period of the stock solution is prolonged, the cost is reduced, the oil stains are collected, the burden of subsequent wastewater treatment is relieved, if the fine oil stains suspended in the liquid medicine are not removed in time, the stability and the cleanness of the tank solution can be influenced, the qualification rate of products is directly influenced, therefore, an oil-water separator needs to be configured in the degreasing process of a coating production line, most of the prior art is manual oil skimming or a high-temperature emulsion breaking type, the cleanliness of a degreasing tank during continuous production cannot be guaranteed by the manual oil skimming, and the skimming is not clean, so that energy is wasted.
Therefore, it is necessary to provide an apparatus and a process for degreasing electroplating degreasing water to solve the above-mentioned problems.
Disclosure of Invention
In order to solve the technical problems, the invention provides electroplating degreasing water degreasing equipment and a process flow, wherein floating oil in degreasing water can be effectively removed.
