The utility model discloses a recycling device for waste heat of tail gas of enameled wire drying furnace, which essentially comprises an enameled wire drying furnace. A hot air circulating device is positioned above the enameled wire drying furnace; a circulating blower, a heater used before catalysis and a catalytic burner are positioned on the hot air circulating device in sequence; the hot air circulating device is also provided with a recycling device for waste heat of tail gas. The recycling device for waste heat of tail gas is provided with a second catalytic burner, a heat exchanger, a waste discharging blower and a chimney. Part of hot air that is in the hot air circulating device and combusted through the catalytic burner returns to the enameled wire drying furnace while the other part enters into the recycling device for waste heat of tail gas; the hot air that is catalytically combusted is treated with secondary catalysis before waste discharge to ensure that the second combustion heat of the residual solvent after the first combustion is used in a steam generator of the heat exchanger and preheating of fresh air; the heat of waste gas is exhausted to atmosphere after being fully used. The utility model is applicable to the production of enameled wire.
Description
Technical field
The utility model relates to a kind of enamel wire drying oven using waste heat from tail gas recycle device.
Background technology
Solvent in the enamel-covered wire usefulness insulated paint, the content of diluent are up to 60-70%, the solvent that uses mostly is aromatic hydrocarbons such as cresols, dimethylbenzene, toluene, these organic substances not only have high fuel value, be generally 9-12kwh/kg, and in the baking finish process, atmosphere is caused certain pollution because of solvent evaporates, therefore, the development and use of this part energy, waste gas is passed through specific catalyst, making flammable pollutant be completely oxidized to CO2 and H2O, is enamel-covered wire enterprise one of the important channel of energy-saving and environmental protection aborning.
Present Production of Enamel Wires equipment is all only equipped a cover catalytic combustion hot air circulating system, organic solvent and diluent vapor are passed through catalyst converter, under the condition of constantly replenishing fresh air, fully burn, generate carbon dioxide and water, and produce a large amount of heats, these heats are sent back in the enamel wire drying oven as thermal source by the circulatory system, be used for evaporating the solvent of lead enamelled coating, diluent and cured paint film, substitute electrical heating, this method greatly reduces energy resource consumption, reduces environmental pollution.But still have some problems, promptly in the Production of Enamel Wires process, the EGT that enters at last in the atmosphere is still quite high, and also contains a certain amount of harmful substance in the waste gas.
Summary of the invention
The purpose of this utility model is the problem at enamel-cover roasting oven tail gas in the above-mentioned Production of Enamel Wires process, and a kind of enamel wire drying oven using waste heat from tail gas recycle device is provided.
In order to achieve the above object, the utility model has mainly adopted following technical scheme to realize.The utility model mainly is made up of enamel wire drying oven, above enamel wire drying oven, be provided with heated air circulation device, on heated air circulation device, be provided with heater and catalytic burner before circulating fan, the catalysis successively, on heated air circulation device, also be provided with the using waste heat from tail gas recycle device.Described using waste heat from tail gas recycle device is provided with quadric catalysis burner, heat exchanger, waste discharge blower fan and chimney.Enamel-cover roasting oven is gone in some time of hot blast through the catalytic burner burning on heated air circulation device; another part enters the using waste heat from tail gas recycle device; with the quadric catalysis before waste discharge of the hot blast behind the catalytic combustion; make after the primary combustion residual solvent once more calory burning be used for the preheating (the essential steam that uses of copper cash Annealing Protection is to avoid oxidation) of the steam generator and the fresh air of heat exchanger.Heat energy from waste gas makes full use of the back and is disposed in the atmosphere by the waste discharge blower fan.
The utility model compared with prior art has following tangible advantage and innovation.(1) reduces pollution.Present Production of Enamel Wires equipment is all only equipped a cover catalytic combustion hot air circulating system, still has some problems, and promptly in the Production of Enamel Wires process, the EGT that enters at last in the atmosphere is still quite high, and waste gas contains a certain amount of harmful substance.And the utility model is to adopt the using waste heat from tail gas recycle device, is about to the hot blast quadric catalysis before waste discharge behind the catalytic combustion, make after the primary combustion residual solvent once more calory burning be used for the pre-heat utilization of the steam generator and the fresh air of heat exchanger.Heat energy from waste gas makes full use of the back and is disposed in the atmosphere by the waste discharge blower fan.This technology has not only reduced content of harmful in the waste gas to greatest extent, the reduction 50% up to standard of toxic emission concentration ratio standard, and reduced power consumption widely.(2) make full use of heat energy.The utility model is in the quadric catalysis combustion process, heat exchange by waste gas and air, preheat fresh air, high-temp waste gas is emitted heat energy, this recirculated hot air passes through the heat exchange of an air and water again, so just, obtain high-temperature-hot-water, be directly used in the steam generator of Production of Enamel Wires equipment.(3) energy savings.The average energy power consumption 530kwh of present enamel-covered wire per ton, and after adopting the utility model, energy consumption per ton can be reduced in 280kwh, economize on electricity 50kwh/ ton, energy consumption reduces by 15.8%.(4) improved the quality of product.The utility model has not only reached energy-conservation good result, and makes the equipment operation more steady, has improved the quality of product, percent defective descends, prolong the service life of equipment simultaneously, significantly reduced the maintenance cost of equipment, therefore had good economic benefit and social benefit.
The utility model is applicable to Production of Enamel Wires.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
