The utility model content
At the problem that prior art exists, the utility model provides a kind of efficient energy-saving gas annealing furnace of effectively avoiding exhaust emission.
For achieving the above object, the provided upstream of combustion gas annealing furnace of the present utility model is equipped with preheating chamber, and wherein the preheating chamber high-temp waste gas of being discharged by the combustion gas annealing furnace is as thermal source, and glass heats by the combustion gas annealing furnace after preheating through preheating chamber again.
Further, between described combustion gas annealing furnace and the preheating chamber recovery channel is set, this recovery channel is provided with induced draft fan, enters preheating chamber by induced draft fan combustion gas high-temp waste gas that annealing furnace is arranged through recovery channel.
Further, described preheating chamber inwall is provided with thermal insulation layer.
Further, be provided with the filtrating smoke dust device in the described recovery channel, this filtrating smoke dust device is used for the flue dust contaminant filter of high-temp waste gas is fallen.
Further, described preheating chamber inside is provided with the airduct of walking that is connected with described recovery channel, walk to be placed with on the airduct tuyere or wind hole, high-temp waste gas imports away airduct and by the tuyere on it or wind hole high-temp waste gas is blown to glass surface through recovery channel glass is preheated.
Further, described preheating chamber inside is provided with the radiator tube that is connected with described recovery channel, and high-temp waste gas imports radiator tube through recovery channel and by thermal radiation glass preheated.
Further, described radiator tube is provided with radiator element.
Further, the described airduct of walking is arranged on the glass bottom or in the glass upper and lower part setting is arranged all.
Combustion gas annealing furnace of the present utility model has the following advantages:
1. with the energy of combustion gas annealing furnace institute waste discharge gas recycle, both effectively avoided high-temp waste gas to discharge the environmental pollution that produces, made full use of gas energy again, cut down the consumption of energy, and improved the heating efficiency of glass, and then increased the production capacity of glass as preheating chamber.
2. adopt two step heating, before entering the tempering process furnace, at first glass has been preheated, prevented problems such as the inhomogeneous glass strain that causes of surface layer of glass and glass core Heating temperature is inhomogeneous, improved the glass yield rate.
