Background technology
Enamelled wire is a principal item of winding wire, is made up of conductor and two ones of insulating barriers, and bare wire forms through repeatedly painting, curing behind annealing softening again.But produce both conformance with standard requirements, satisfy the product of customer requirement again, must satisfy mechanical performance; Chemical property; Electrical property, the standard-required of hot property four big performances, these performances of enamelled wire receive the influence of factors such as raw material quality, technological parameter, production equipment, environment again; Therefore, improving production equipment improves production environment and helps improving quality of enamelled wire.Meanwhile, the Production of Enamel Wires process also is the energy consumption rich and influential family, if having an important economic implications through the optimization implementation of production technology is energy-conservation.
The insulating varnish that Production of Enamel Wires is used can produce a large amount of solvent vapours in high-temperature baking process baker; If directly discharging; Can cause serious pollution to environment, therefore catalytic combustion workshop section generally is set in baker at present, with discharging again behind the solvent vapour process catalytic combustion that produces.Through behind the catalytic combustion, though tail gas pollution is under control, great amount of heat had both been taken away in the direct discharging of the high-temperature flue gas that produces in the stove; Cause the waste of the energy; Cause simultaneously the workshop temperature to raise again, workman's operating environment worsens, equipment component; Especially the service behaviour variation of air draft blower fan influences ordinary production.
In order to solve the too high problem of workshop summer temp, the wall and the roof that generally are employed in the workshop increase a large amount of blower fans, and the mode for the workshop ventilation reduces the workshop temperature through bringing a large amount of fresh airs into.But the use of a large amount of blower fans had both increased energy consumption, had added wind and these two kinds of destabilizing factors of dust for the production of enamelled wire again.Wind can make enamelled wire produce dense particles from small to large; Dust can make enamelled wire play more foreign particle; All influence the viscosity of coating with lacquer with cold sky hot summer days; Can make enamelled wire play many lacquer particles, therefore, become an important step that improves the enamelled wire product quality for the Production of Enamel Wires workshop provides a constant temperature, cleaning, dustless production environment.
To characteristics such as Production of Enamel Wires process exhaust emissions temperature height, Workshop Production environment differences, need a waste heat recovery and utilize system and method, fully reclaim the energy of high-temp waste gas, improve operational environment and improve the quality of products.
