Description
Technical field
The utility model technology relates to a kind of galvanized steel strip annealing furnace power-saving technology, is related specifically to a kind of galvanized steel strip annealing furnace energy-saving structure.
Background technology
For improving the production efficiency of galvanized steel strip annealing furnace, usually adopting and lengthening furnace binding.Make heating tape have longer length by lengthening body of heater, galvanized steel strip also can fully be heated when speed is run faster.Usually, galvanized steel strip annealing furnace is provided with preheating section, naked light section and waste heat section; Preheating section carries out preheating to galvanized wire, and naked light section heats galvanized steel strip, and waste heat section ensures the cooling rate of galvanized steel strip.Not oxidized when naked light section heats for ensureing galvanized steel strip, usually need to control the atmosphere of naked light section fuel gas buring, namely adjust the ratio of combustion gas and air, make combustion gas burn incompletely, make combustion gas superfluous, make the furnace atmosphere of naked light section for reduction atmosphere.But, if do not reclaimed the residual air that naked light section is sent, then may cause that namely combustion gas is imperfect combustion is excluded, cause the wasting of resources.Obviously, prior art galvanized steel strip annealing furnace also exists not to be recycled the residual air of reducing atmosphere, causes the problems such as the wasting of resources.
Summary of the invention
For solving not recycling the residual air of reducing atmosphere of prior art galvanized steel strip annealing furnace existence, causing the problems such as the wasting of resources, the utility model proposes a kind of galvanized steel strip annealing furnace energy-saving structure.The utility model galvanized steel strip annealing furnace energy-saving structure, comprise and lengthen body of heater, smoke discharging pipe and smoke exhaust fan, it is characterized in that, in the waste heat section lengthening body of heater, burner kept burning day and night and combustion-aid air pipe are set, at smoke discharging pipe, the junction lengthening body of heater waste heat section is provided with gas flow and controls air lock, controlling the smoke discharging pipe on rear side of air lock is provided with air-cooler, on rear side of air-cooler, smoke discharging pipe is disposed with heat exchanger I, heat exchanger II and heat exchanger III; Described heat exchanger I is connected with combustion air heater, and described heat exchanger II is connected with air heater, and described heat exchanger III is connected with water for cleaning heater.
Further, the smoke discharging pipe of heat exchanger I front end is provided with temperature sensor.
The Advantageous Effects of the utility model galvanized steel strip annealing furnace energy-saving structure both effectively can improve the production capacity of galvanized steel strip annealing furnace, again can Appropriate application waste heat, reached energy-saving and cost-reducing object.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model galvanized steel strip annealing furnace energy-saving structure.
Below in conjunction with the drawings and specific embodiments, this utility model galvanized steel strip annealing furnace energy-saving structure is further described.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the utility model galvanized steel strip annealing furnace energy-saving structure, and in figure, 1 for lengthening body of heater, and 2 is smoke discharging pipe, and 3 is smoke exhaust fan, and 4 is burner kept burning day and night, and 5 for controlling air lock, and 6 is air-cooler.As seen from the figure, the utility model galvanized steel strip annealing furnace energy-saving structure, comprise and lengthen body of heater 1, smoke discharging pipe 2 and smoke exhaust fan 3, it is characterized in that, in the waste heat section lengthening body of heater 1, burner 4 kept burning day and night and combustion-aid air pipe are set, at smoke discharging pipe 2, the junction lengthening body of heater waste heat section being provided with gas flow and controlling air lock 5, controlling the smoke discharging pipe 2 on rear side of air lock 5 is provided with air-cooler 6, on rear side of air-cooler 6, smoke discharging pipe being disposed with heat exchanger I, heat exchanger II and heat exchanger III; Described heat exchanger I is connected with combustion air heater, and described heat exchanger II is connected with air heater, and described heat exchanger III is connected with water for cleaning heater.Further, the smoke discharging pipe of heat exchanger I front end is provided with temperature sensor.The utility model galvanized steel strip annealing furnace energy-saving structure, lengthen the waste heat section of body of heater by being arranged on burner kept burning day and night is set and combustion-aid air pipe makes the sufficient residual air of unburned burn completely in waste heat section, and control smoke evacuation flow and furnace inner gas pressure by controlling air lock, make residual air Thorough combustion in stove and galvanized steel strip is heated.For ensureing that the hot gas entering heat exchanger I has applicable temperature, the smoke discharging pipe of heat exchanger I front end is provided with temperature sensor, by detecting ducted hot gas temperature, thus determine the air output of air-cooler, keep the temperature be applicable to after the cold wind of hot gas and the air-cooler of discharging from body of heater is mixed.The utility model heat exchanger I is connected with combustion air heater, for heating the air needed for body of heater burning, thus improves the efficiency of combustion of body of heater; Heat exchanger II is connected with air heater, and for heating air, the hot-air after heating can be used for drying plant and the warming-up device of galvanized steel strip by pipeline; Heat exchanger III is connected with water for cleaning heater, can be used for the alkali lye to pre-treatment, cleaning fluid, water etc. and heats; After three heat exchangers, body of heater residual air finally enters chimney and is discharged.
Obviously, the Advantageous Effects of the utility model galvanized steel strip annealing furnace energy-saving structure both effectively can improve the production capacity of galvanized steel strip annealing furnace, again can Appropriate application waste heat, reached energy-saving and cost-reducing object.
