Description
Technical field
The present invention relates to recycling of recyclable waste and reutilization technology field, more particularly to a kind of continous way enamel-covered wire depainting
Method and system.
Background technology
China's copper ore resource lacks, and waste metal recovery mixed cropper regeneration utilization, which accounts for copper production proportion, increasingly to be increased, 2010
China's regeneration Copper making has occupied copper yield 30% or so then, and the data in 2014 rise to 40% or so, but and World Water
Larger gap also be present in flat compare.Enamel-covered wire is manufacture motor, electrical equipment, the critical material of telecommunication instrument electromagnetism winding, is composition brass
The main source of recovery.China is Production of Enamel Wires big country, and the import big country of waste enameled wire, greatly develops enamel-covered wire recovery
It is the most important approach for realizing Copper making industry energy-saving emission reduction to regenerate copper technology.
The depainting of enamel-covered wire is the key technology of enamel-covered wire recovery.The method of enamel-covered wire depainting is more, and the country has earlier
Manually scrape paint, machinery is scraped and painted and using paint stripper.It is artificial to scrape that paint speed is slow, the amount of labour is big；Machinery scrapes paint because insulated paint is rich
It is flexible and have resistance to scraping, tend to scrape disconnected, cause powder more, environmental pollution, copper loss lose it is serious, and scrape need after paint into
The separation of one step, recovery copper purity is not high.
The composition of wire enamel mainly includes polyester-imide, acetal, polyamidoimide, polyurethane, polyester etc..Paint stripper
Method is the side for aoxidizing insulated paint using the inorganic paint stripper such as strong acid or highly basic (such as concentrated sulfuric acid, nitre sulfuric acid, nitric acid), being removed
Method.Depainting agent method overcome it is artificial and it is mechanical scrape subproblem existing for paint method, but itself have that depainting speed is slow, recovery
Purity is low, paint stripper limitednumber, volatility are big, operates the limitations such as inconvenience to base material burn into.
Wire enamel more than 100 DEG C just start be pyrolyzed aging, to 600~750 DEG C pyrolysis complete, weight-loss ratio reach 90% with
On.Therefore, pyrolysis wire enamel turns into a kind of very effective enamel-covered wire recovery method, by domestic widely used.It is domestic at present
Enamel-covered wire centralized burning is mainly realized into production in enormous quantities in this way, however, copper loss is lost sternly in burning process
Weight, burns the grade of copper also less than 92%.At present it is proposed that the composition brass recovery work of smelting is burnt in a kind of circulation of high-temperature vacuum nitrogen charging
Skill, copper that obtained light, that purity is higher.However, the method for the pyrolysis recovery reported at present is intermittent method, often give birth to
Produce a batch of material and be required for experience once heating and temperature-fall period, do not only exist high energy consumption, the problem of production cycle is long, product
Yield and quality also need further to be improved.
The content of the invention
