Description

Raw material dehumidifying equipment for glass production
Technical Field
The utility model relates to the technical field of glass production equipment, in particular to raw material dehumidification equipment for glass production.
Background
The boron oxide (B 2O3) has the functions of increasing the low-temperature viscosity and reducing the high-temperature viscosity of glass, and has very high heat absorption coefficient and mass absorption coefficient, and the high-middle-low borosilicate glass can be produced by adding boron element (borax pentahydrate) in glass production, so that the glass has excellent chemical stability, lower heat expansion coefficient and good mechanical property, and has been widely applied to the fields of precision photoelectricity and medical glass tube control bottles.
However, the volatilization of B 2O3 and B 2O3 is easy to cause the volatilization of B 2O3 due to the high temperature in the glass melting furnace in the glass production, so that a large amount of raw materials are consumed, the quality of the glass is reduced, the furnace is greatly corroded, the service life of the furnace is shortened, boron oxide (boron oxide) is discharged into the environment along with flue gas, and boric acid generated by the reaction of boron oxide and water in the air causes acid rain, so that the environment is polluted. Secondly, due to the chemical characteristics of the boron oxide, a great amount of volatilized boron oxide and mixtures thereof are contained in the flue gas discharged by the kiln, and the problems of adhesion, blockage and the like are formed on a flue gas path due to the fact that the boron oxide can exist in solid, liquid and gas at different temperatures, so that the normal operation of flue gas treatment equipment is seriously influenced, and the stability of the kiln pressure is influenced to a certain extent. A large amount of B 2O3 contained in the flue gas can cause the flue gas dew point to be higher, the phenomenon of dew condensation is easy to generate, the conditions of residual adhesion of the inner wall of a flue, bag pasting of a dust collector bag and the like can be caused in the middle section and the tail section of the environment-friendly dust collection system, and finally the standard emission is influenced.
Boride in the glass melting furnace flue gas is derived from the added borax raw material, the content of B 2O3 in the medium-high boron glass batch is more than or equal to 47.50, the melting point of boron oxide is 450 ℃, the boron oxide is easy to volatilize at low temperature, and the conversion of boric acid into boride is a gradual dehydration process along with the temperature rise. Under the high temperature of 1500 ℃ of the glass melting furnace, the volatilization rate of B 2O3 in the glass batch is 8.9-12.78%, so B 2O3 becomes the source of boride in the flue gas of the glass melting furnace.
According to the research, water vapor in (Wenzel J T,Sanders D M.Sodium and boron vaporization from a boric oxide and a borosilicate glass melt【J】.Physics and chemistry of Glass,1982,23(2):47-53.), flue gas is easy to generate metaboric acid with liquid B 2O3, so that volatilization of boron is promoted, the volatilization amount of boron is proportional to the partial pressure of water vapor, so that the higher the water content of the batch is, the higher the partial pressure of water vapor in melting is, and the volatilization amount of B 2O3 is also higher, namely, the reduction of the water content in raw materials is an effective means for reducing the boron oxide content of the flue gas.
According to the important point, the dehumidification equipment provided by the invention pretreats raw materials (a plurality of process factors (J) influencing volatilization of boron oxide when glass such as Qiandaxing is melted; building materials journal, 1998,1 (2); 197-200), and reduces the volatilization amount (50% of the total amount of the existing boron oxide) of the glass melting furnace B 2O3 by reducing the water content of the raw materials, so that the concentration of boride in discharged flue gas is reduced from the source.
