Environment-friendly and high-efficiency heat-exchanging glass melting furnace and production method

Abstract

The invention relates to an environment-friendly, highly-efficient and heat-exchangeable glass melting furnace and a production method. The glass melting furnace is divided into 3 areas in a lengthwise direction: a first feeding and premelting area has the following functions: adding raw materials from any part of the area, absorbing the heat of a combustion product flowing from a second melting, homogenizing and clarifying area, premelting the raw materials, allowing the premelted raw materials to flow into the second area for melting, homogenizing and clarifying, and discharging a cooled combustion product to a heat exchanger at the exterior of the furnace from the end head of the melting furnace; the second area has the following functions: spraying a fuel from any part of the area, allowing the fuel to perpendicularly intersect with air or oxygen from a third cooling area of the furnace and carrying out mixed combustion, heating a glass liquid flowing from the first area to a temperature needed for homogenizing and clarifying, allowing the heated glass liquid to flow into the third area, and allowing a generated high-temperature combustion product to enter the first area; and the third area has the following functions: cooling the glass liquid flowing from the second area to a temperature needed for shape formation, allowing the cooled glass liquid to flow out of the furnace, wherein the glass liquid is cooled mainly by spraying air or oxygen of the heat exchanger from the terminal end of the area besides heat dissipation of a melt, and allowing heated air or oxygen to enter the second area for combustion supporting. The environment-friendly, highly-efficient and heat-exchangeable glass melting furnace provided by the invention has the advantages of low tail gas emission temperature, insusceptibility to ablating a furnace-gas heat-exchange device, easy cooling of the cooling area and high production efficiency.

Description

technical field [0001] The invention relates to a glass melting furnace, in particular to an environment-friendly and high-efficiency heat-exchanging glass melting furnace and a production method. Background technique [0002] On the one hand, the existing glass melting furnace has the problems that the high temperature of the discharged furnace gas is easy to ablate the heat exchange chamber or the regenerator, wastes energy, and is not conducive to the environmental protection of the exhaust gas. In addition, it is difficult to cool down the cooling area and affects the production efficiency. . Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, and provide an environmentally friendly and high-efficiency heat exchange glass melting furnace with low exhaust gas discharge temperature, no ablation of furnace gas heat exchange equipment, easy cooling of the cooling zone, and high production effi...
