Description
Technical Field
The invention relates to the technical field of glass production, in particular to a method for improving the performance of a glass flame melting furnace by using a multifunctional material.
Background
China is the country with the largest global glass yield, the plate glass yield in 2021 years is 102360 ten thousand weight boxes, the year-on-year increase is 8.23%, and the stable increase is kept. The plate glass is mainly used for doors and windows, show windows, mirrors and the like of civil buildings and commercial buildings, and can also be used for processing and manufacturing safety glass such as toughened glass, interlayer glass and the like.
Glass is an amorphous solid material prepared by high-temperature melting and reaction, the raw material for preparing the glass can be melted when the temperature in a melting furnace for preparing the glass reaches more than 1500 ℃, but a large part of heat in the furnace is radiated through the glass melting furnace and is lost by tail gas emission, and meanwhile, a refractory material in the melting furnace is corroded in harsh environments such as high temperature, gas released by the raw material and the like, so that the service life of the glass melting furnace is shortened.
The glass melting furnace is a heating device for melting glass raw materials in glass manufacturing, and the glass melting furnace has great difference in structural form due to different adopted heat sources, such as a flame melting furnace, an electric melting furnace and a flame-electric melting furnace. The raw materials distributed according to the glass composition are melted and reacted at high temperature in a kiln, and are clarified to form molten glass meeting the forming requirement. The glass melting furnace has two types of intermittent type and continuous type, the intermittent type melting furnace is generally smaller and is suitable for producing special glass, a continuous type coal-fired melting furnace is built in 1867 German Siemens brother, the continuous type glass melting furnace is rapidly developed after 1945, at present, most of melting furnaces belong to the continuous type, raw materials are subjected to the advancing processes of melting, clarifying and homogenizing molten glass, the raw materials are transferred to a cooling part for further homogenizing and cooling, then the raw materials enter a forming area for finally homogenizing and stabilizing the feeding temperature.
At present, the glass melting kiln at home and abroad not only has requirements on daily output, but also has limitation on the minimum service life of the kiln, so that stricter performance indexes are provided for refractory materials of the glass melting kiln, however, conventional silica bricks are easily corroded in a harsh environment with high temperature and high alkaline gas, in addition, the radiation heat transfer of the silica bricks is reduced along with the temperature rise, the infrared radiance of the silica bricks is less than 0.5 at the working temperature of the glass melting kiln, the surfaces of the silica bricks are continuously corroded, and the radiance is continuously reduced. The heat is mainly transferred through radiation in the glass melting and reaction processes, the radiation transfer heat of the inner wall of the glass melting furnace occupies 60%, the heat absorbed by the refractory material of the inner wall of the melting furnace is transferred through three forms, firstly, the heat is transferred to the outside of the furnace through the refractory material, secondly, the glass raw material is heated by radiation infrared rays, thirdly, the reflected heat is absorbed by smoke and discharged out of the furnace, the higher the reflectivity is, the greater the heat loss is, the radiation emissivity of the inner wall of the glass melting furnace is obviously improved, and the energy lost by heat conduction and reflection is obviously reduced. At high temperature, infrared waves with certain penetrating power are radiated from the inner wall, so that the glass raw material generates molecular oscillation, energy level transition is generated, infrared rays with certain wave bands are radiated, heat is generated, the glass raw material is uniformly heated and is heated from inside to outside, the heating time of the raw material is shortened, and the energy utilization rate is improved. For example, CN 100381516C, CN 106587892B, CN 106084908B and other patents all adopt high-radiation materials such as nitrides, borides, carbides and silicides, which are very easy to decompose at high temperature, and although protected by a binder, the infrared radiation rate of the inner wall gradually decreases within 1 year of the operation of the glass melting furnace; in addition, compounds such as zircon sand, alumina, kaolin, rare earth oxide and the like are subjected to chemical reaction among the radiation materials at high temperature, and the coating has cracking and even falling-off phenomena and also has a phenomenon of reducing the radiation rate.
