Quadric catalysis method of enamel wire drying oven

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 [0001] The invention relates to a production process of enameled wire, in particular to a catalytic process of enameled wire. Background technique [0002] In the production process of enameled wire, it is necessary to use an oven to plate insulating varnish on copper wires. The enameled wire insulating varnish used contains up to 60-70% organic solvents (such as cresol, xylene, toluene, etc.) and thinners. These organic solvents and thinners will volatilize during the baking process. If they are directly discharged into the atmosphere, they will cause certain pollution to the atmosphere. [0003] The current enameled wire production enterprises generally only install a set of catalytic combustion devices (that is, primary catalytic combustion devices) in the baking furnace. Organic solvents and diluents generate carbon dioxide gas and water vapor after primary catalytic combustion. This method can reduce the content of organic solvents and thinners directly...

AI Technical Summary

Problems solved by technology

This method can reduce the content of organic solvents and thinners directly discharged into the atmosphere, and reduce the pollution to the atmospheric environment, but it does not completely decompose the volatilized organic solvents and thinners after baking, and still has a considerable part of Solvents and diluents are directly discharged into the atmosphere because they cannot be obtained or burned in time, causing certain pollution and damage to the atmospheric environment
