Description
Technical field
The utility model relates to enamel-covered wire and covers and be coated with paint film and cure dry equipment, particularly the discharging waste gas behind the catalytic combustion is reduced to the minimum equipment of discharging again, relates in particular to many online equipment that focus on tail gas of enamelling machine.
Background technology
At present, annual solvent (cresols and the dimethylbenzene) 150,000 tons that consumes of enamel-covered wire industry, energy consumption 12.24 hundred million kilowatt hours (amounting to 49.5 ten thousand tons in mark coal) are discharged 300 ℃ organic exhaust gas 15.3 billion cubic meters.
The comprehensive programme of work of State Council's energy-saving and emission-reduction: 2010, ten thousand yuan of GDP energy consumptions of China will drop to 1 ton below the standard coal by 1.22 tons of standard coals in 2005, reduce about 20%; Unit industrial added value water consumption reduces by 30%.The Eleventh Five-Year Plan period, Chinese total emissions of major pollutants reduces 10%.
By 2010, SO2 emissions reduced to 2,295 ten thousand tons by 2,549 ten thousand tons in 2005, and COD (COD) reduces to 1,273 ten thousand tons by 1,414 ten thousand tons; The whole nation is established city's treatment rate of domestic sewage and is not less than 70%, and percentage of industrial solid waste that is comprehensively utilized reaches more than 60%.
In the Production of Enamel Wires industry of prior art, aspect reducing cost, many producers undergo technological transformation to existing equipment successively, and have applied for some patents.
The applicant also just makes full use of catalytic heat energy, and saves energy is produced the problem of enamel-covered wire and made a series of technological transformation, and has applied for some patents, as:
200910105133.4, a kind of method and apparatus of enamelling machine reasonable catalytic combustion thermal energy distribution;
200910106213.1, a kind of enamelling machine hot air mixing chamber and hot air mixing method;
