Embodiment Construction

[0026] In the following, the technical means adopted to realize the object of the present invention and its effects will be described by taking the preferred embodiment as an example in conjunction with the accompanying drawings.

[0027] The invention firstly discloses a waste heat recovery and utilization method in the production of enameled wire, the following is combined with the attached figure 1 The flow of waste heat recovery and utilization will be described in detail. During the baking process of the enameled wire in the oven, exhaust gas with high heat is generated. These exhaust gases are mainly formed by burning high-content solvents and thinners in the insulating varnish for enameled wire. These substances have high combustion values. Generally, It is 9-12kwh / kg, and its components are generally cresol, xylene, toluene and other aromatic hydrocarbons. Direct emission will lead to waste of heat energy and environmental pollution. Therefore, firstly, these exhaust g...

Abstract

The invention relates to afterheat recycling method and device thereof in enamelled wire production. The device comprises two heat collectors which are respectively a heat collecting pipe and a coil, and the heat collecting pipe and the coil finish twice afterheat collections and twice afterheat transmissions respectively through two heat transmission pipelines, wherein the quantities of heat transmitted each time are different and respectively applied to heating processes of different degrees of an annealing furnace so as to ensure that the use of electric energy of the annealing furnace originally required to be electrically heated is reduced, thereby greatly improving the utilization of the afterheat and reduce the emission of pollutions.

Description

technical field [0001] The invention relates to a method and a device for realizing energy saving and emission reduction in the production of enameled wires, in particular to a method and device for recycling waste heat in the production of enameled wires. Background technique [0002] Enameled wire is an important raw material in mechanical and electronic equipment. With the popularization of electronic equipment and instruments, on the one hand, it has greatly promoted the development of social productivity, and on the other hand, the demand for enameled wire has greatly increased. How to produce enameled wire? Achieving energy saving, waste heat utilization, emission reduction, and reducing the emission of polluting gases have become the key technology development direction of enameled wire production enterprises. Especially in the oven, the volatilized solvent vapor in the oven, on the one hand, has a lot of heat to use, on the other hand, it has a lot of pollution. When...
