A waste heat recovery device in enameled wire production

Abstract

The invention discloses a waste heat recovery device in enameled wire production, The invention relates to the technical field of enameled wire production, comprising a recovering device body, whereinthe recovering device body comprises a drying oven, an exhaust gas discharge pipe, an air guide chamber, a first catalytic combustion chamber, a second catalytic combustion chamber, a suction fan, anannealing oven and an air outlet; and an upper side of one end of the drying oven is fixedly connected with one end of the exhaust gas discharge pipe. The waste heat recovery device in the enameled wire production, while the second catalytic combustor may reburn exhaust gases that are not burned clean inside the first catalytic combustor, On the other hand, the suction fan can suck the outside air into the inside of the first heat collecting pipe and the second heat collecting pipe respectively. After the outside air is heated in the inside of the first heat collecting pipe and the second heat collecting pipe, the outside air is finally returned to the oven for reuse.

Description

technical field [0001] The invention relates to the technical field of enameled wire production, in particular to a waste heat recovery device in enameled wire production. Background technique [0002] At present, during the production process of enameled wire, the solvent vapor and other exhaust gases volatilized in the oven are directly discharged into the air. On the one hand, it will cause a certain degree of pollution to the air; on the other hand, the discharged solvent vapor and other exhaust gases carry a lot of heat and are directly discharged, which wastes a lot of heat energy. At present, the annealing process in the production of enameled wire is to heat the advancing copper wire in the annealing furnace chamber. The air in the furnace chamber will accelerate the oxidation of the copper wire during heating. At the same time, more heat is required to heat the air from room temperature to the temperature in the furnace. [0003] The heat recovery device on the ena...
