Abstract
The invention discloses a secondary catalysis method of an enameled wire oven. The method comprises the following steps: a secondary catalytic combustion device is additionally arranged in an exhaust gas discharge channel of the enameled wire oven, secondary catalytic combustion is carried out on the exhaust gas for which primary catalytic combustion is carried out before being discharged by an exhaust fan by virtue of the secondary catalytic combustion device, therefore, the residual organic solvent and diluent in the exhaust gas after the primary catalytic combustion are completely oxidized into carbon dioxide and water vapor after the secondary catalytic combustion. The secondary catalysis method can completely decompose the organic solvent and the diluent with benzene volatilized by the enameled wire oven after baking varnish, thus minimizing the contents of hazardous substances discharged into the atmosphere, and effectively preventing pollution and damage to the atmospheric environment; the secondary catalysis method has significant social and economic benefits in solving pollution problems of enameled wire production enterprises, energy saving and environmental protection.
Description
Technical field
The present invention relates to the Catalytic processes of a kind of production technology of enamel-covered wire, particularly a kind of enamel-covered wire.
Background technology
In the production process of enamel-covered wire, need to use baker that insulated paint is plated on the copper cash, contain organic solvent (such as cresols, dimethylbenzene, toluene etc.) and diluent in the used enamelled wire insulated paint up to 60～70%, these organic solvents and diluent can vapor away in the baking finish process, if directly drain in the atmosphere, can cause certain pollution to atmospheric environment.
A cover catalytic combustion system (i.e. catalytic combustion system) is generally all only installed by present Production of Enamel Wires enterprise in oven, organic solvent and diluent pass through to generate carbon dioxide and water vapour behind a catalytic combustion.This method can reduce the organic solvent that directly drains in the atmosphere and the content of diluent, reduction is to the pollution of atmospheric environment, but fully the organic solvent and the diluent branch that volatilize after the baking finish are not taken off, still there are quite a few organic solvent and diluent directly to drain in the atmosphere, atmospheric environment is caused certain pollution and destruction because of can not get or have little time burning.
Summary of the invention
Technical problem to be solved by this invention is, a kind of quadric catalysis method of enamel wire drying oven is provided.Organic solvent and the abundant combustion decomposition of diluent through volatilizing after the baking finish in the enamel wire drying oven organic solvent and the amount of diluent that drains in the atmosphere be can be reduced to greatest extent by this method, pollution and destruction significantly reduced atmospheric environment.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the quadric catalysis method of enamel wire drying oven.This method is to add the quadric catalysis burner in the toxic emission passage of enamel wire drying oven, by this secondary device waste gas is carried out the quadric catalysis burning before draining into atmosphere by the waste discharge blower fan, make organic solvent remaining in the waste gas and diluent through being completely oxidized to carbon dioxide and water vapour behind the catalytic combustion once more.
The quadric catalysis method of above-mentioned enamel wire drying oven is said accurately, and the quadric catalysis burner is arranged in the toxic emission passage of enamel wire drying oven, and this quadric catalysis burner is the top that is positioned at a catalytic combustion system of enamel wire drying oven.
The quadric catalysis method of aforesaid enamel wire drying oven, quadric catalysis burner are to be made of catalytic combustor, cellular catalysis piece and electric heater; Electric heater is positioned at the top of a catalytic combustion system, and cellular catalysis piece is positioned at the top of electric heater, and catalytic combustor is positioned at the top of cellular catalysis piece.
Beneficial effect: the present invention adds the quadric catalysis burner in the toxic emission passage of enamel wire drying oven, by the quadric catalysis burner residual organic solvents that contains benzene behind catalytic combustion and diluent are carried out the quadric catalysis burning before draining into atmosphere by the waste discharge blower fan, make remaining organic solvent and diluent be completely oxidized to carbon dioxide and water vapour (water vapour can carry out the secondary utilization), thereby the organic solvent that contains benzene that volatilizees after the baking finish and diluent divided fully take off, reduce the content of harmful that drains in the atmosphere to greatest extent, effectively avoid organic solvent and diluent directly to drain into the pollution and the destruction of in the atmosphere atmospheric environment being caused because of can not get or have little time burning.The heat that quadric catalysis burning is discharged can be used to heat fresh air after heat exchanger carries out heat exchange, the hot-air that produces behind the heating fresh air can be back in the air intake passage of enamel wire drying oven recycling again; And carbon dioxide that quadric catalysis burning generates and steam are can be via the toxic emission passage of enamel wire drying oven up and enter in the steam generator, after process is shunted and is handled in steam generator, water vapour enters steam pipeline and is delivered to by steam pipeline and carries out the secondary utilization in the corresponding apparatus, and carbon dioxide then enters exhaust pipe and is disposed in the atmosphere by the waste discharge blower fan.The present invention can divide the organic solvent that contains harmful substances such as benzene that volatilizees after the baking finish in the Production of Enamel Wires and diluent fully and takes off, to reduce pollution and the destruction that atmospheric environment is caused, realized the secondary utilization of the energy and waste gas again, characteristics with energy-conservation, reduction of discharging, environmental protection, to the pollution problem of solution Production of Enamel Wires enterprise, and energy-saving and environmental protection have important social and economic benefit.
Description of drawings
Fig. 1 is the structural representation of quadric catalysis burner of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment.As shown in Figure 1, in the toxic emission passage 1 of enamel wire drying oven, be provided with catalytic combustor 2, cellular catalysis piece 3 and electric heater 4, electric heater 4 is positioned at the top of a catalytic combustion system 5, cellular catalysis piece 3 is positioned at the top of electric heater 4, and catalytic combustor 2 is positioned at the top of cellular catalysis piece 3; Wherein a catalytic combustion system 5 is a prior art.Cellular catalysis piece 3 can be provided with 1～5 layer according to the content of organic solvent in the waste gas and diluent, and (content of organic solvent and diluent is high more, the number of plies of cellular catalysis piece 3 is also many more), three layers of operated by rotary motion, it is to carry out the quadric catalysis burnt fuel, and the heat that cellular catalysis piece 3 burnings produce can be recycling; Electric heater 4 is used for when the firm blow-on of enamel wire drying oven cellular catalysis piece 3 being carried out preheating, makes cellular catalysis piece 3 can reach initiation temperature; Catalytic combustor 2 is used to burn.
During work, the waste gas that contains organic solvent and diluent that comes out from enamel wire drying oven enters the toxic emission passage 1, continue to move upward behind the catalytic combustion through a catalytic combustion system 5, and contact the back with the cellular catalysis piece 3 of burning and in catalytic combustor 2, carry out quadric catalysis and burn, organic solvent that contains benzene and diluent remaining in the waste gas are completely oxidized to carbon dioxide and water vapour (but the utilization of water vapour secondary) after the quadric catalysis burning, the waste gas that reaches national environmental standard after the burning drains in the atmosphere by the waste discharge blower fan.
