Abstract
The invention relates to an on-line recycling method for steel strip continuous copper plating. The method is mainly used for recycling acid-base cleaning water, copper plating cleaning water and copper plating liquid during the process of steel strip continuous copper plating. A water collecting tank, a security filter, a fine filter and a RO (Reverse Osmosis) film treating system are utilized to treat the acid-base wastewater so as to turn the wastewater into pure water; the pure water is stored in a clean water tank; and then a pump is utilized to pump the pure water into a cleaning tank for recycling. An atomizing spraying device is utilized to scour the plating solution taken out of the tank by the steel strip; after being filtered, the plating solution is stored in a plating solution concentrating tank; and the pump is utilized to pump the plating solution into a plating tank for recycling. The water collecting tank, the security filter, the fine filter, an ultra-filtration system and the RO film treating system are utilized to treat copper plating cleaning water, thereby obtaining thick water and pure water. The pure water is stored in the clean water tank and then the pump is utilized to pump the pure water into the cleaning tank for recycling. After the thick water is concentrated, the thick water is reused in the plating tank. The solid impurities after being filtered are subjected to plate pressing forming and then are treated by a professional company. The acid-base cleaning water, the copper plating cleaning water and the copper plating liquid are recycled; the discharging of wastewater is reduced; the resource is saved; and the pollution is reduced.
Description
Technical field
The present invention relates to Industrial Wastewater Treatment and resource and reclaim field, specifically a kind of method of continuous copper-plating of steel strip online recycling.
Background technology
Along with China's industrial expansion, the especially develop rapidly of automobile and other industries, increases day by day to the demand of copper and brass work.But China is a poor copper country, and the main dependence on import of copper, adds copper price moving quickly upward in the world, bring larger cost pressure to the industries such as China's automobile.Through demonstration and facts have proved, at automobile, the industries such as household electrical appliances, it is feasible that steel copper facing goods replace brass work, performance even is in some aspects more better than copper on the contrary.Copper facing steel band is mainly used to produce side enlightening pipe, is generally applied in the aspects such as automobile oil pipe, floor heating pipe, air-conditioner pipe.The still economic problems that use iron instead of copper not, can also reduce carbon emission in a large number.Steel band copper facing has good Social benefit and economic benefit thus.Utilize cyanide electroplating, can obtain densification, the coating that smooth, bonding force is good, so continuous copper-plating of steel strip adopts cyanide copper plating process.
In continuous copper-plating of steel strip is produced, need to consume a large amount of pure water, and rinse water accounts for major portion.Waste water after cleaning is owing to containing a large amount of acid-base materials, heavy metal (Cu
2+) and toxic substance (CN
-), cause utilizing.Must focus on sewage works and process, discharge.Like this, in plating shop, will waste a large amount of water resourcess.Further, in electroplating process, have a certain amount of plating solution and take out of, discharge with waste water.Owing to containing plurality of heavy metal (Cu in plating solution
2+) and toxic substance (CN
-), will work the mischief to environment, and waste resource, this does not meet the cleaner production standard of electroplating industry.In recent years, in chemical industry, especially electroplating industry, country actively advocates online recycling, realizes " zero release ".So it is imperative taking measures to make waste water, the utilization of waste liquid online recycling.
Summary of the invention
For the problems referred to above, the invention provides kind of a method for continuous copper-plating of steel strip online recycling.
The method of a kind of continuous copper-plating of steel strip online recycling of the present invention, mainly utilize header tank, security personnel's filter, microfroc filter, RO film processing system, ultrafiltration system, atomizing sprayer, filtered water tank, pump etc., after soda acid rinse water, copper facing rinse water and copper plating bath are processed, recycle.
The processing of acidic and alkaline waste water and recycling.Soda acid Cleaning Wastewater focuses in header tank, carry out acid-base neutralisation processing, then utilize security personnel's filter to filter, filter out the particle that is greater than 5 microns, recycling microfroc filter filters, and the water conservancy after filtering is obtained to pure water with the processing of RO film, and pure water is focused in filtered water tank, finally utilize pump, the pure water pump in Rinsing Area is delivered to each and use water spot.
The recycling of plating solution.When steel band goes out groove, will take a certain amount of plating solution out of.Utilize the water smoke that atomizing sprayer mesohigh shower nozzle sprays that plating solution remaining on steel band is rinsed, and collect and concentrate in groove, owing to rinsing, the bath concentration getting off is higher, after filtering, removes impurity, can be in the recycling of arriving being pumped in coating bath.
The processing of copper facing rinse water and recycling.Copper facing Cleaning Wastewater focuses in header tank, filter with security personnel's filter, filter out the particle that is greater than 5 microns, recycling microfroc filter filters, and the water after filtering is processed by ultrafiltration system, and the most of colloid silicon containing in water is removed, can remove a large amount of organism etc. simultaneously, then utilize RO membrane technique to process, will obtain dense water and pure water, focus on respectively in dense water tank and filtered water tank.Finally utilize pump, the dense water in dense water tank is transported in coating bath and is recycled, the pure water pump in filtered water tank is delivered to each and use water spot.
The impurity filtering out in said process is collected, after plate is molded, transferred to specialized company to process.
The present invention makes waste water and the waste plating solution in electroplating process obtain recycling, has saved resource, and economic environmental protection meets national cleaner production standard.
