Abstract
A kind of high-temperature gas submergence bubbling fusing production method of glass, it is characterized in that：It will burn, the high-temperature gas that electromagnetic heating or heating plasma produce, in a manner of small flow, large area bubbling, blast in glass metal, then while by glass liquid heating, enable glass metal clarification and homogenization.The bubbling device of high-temperature gas is the high temperature resistant tracheae for crossing glass melting pond；High-temperature gas is blasted into tracheae, and at least row's bubble holes by being opened up on tracheae side wall, bubble is blasted in glass metal.Making tracheae make tracheae constantly be able to update replacement, so as to ensure the permanently effective use of tracheae by way of glass melting pond side is continuously intermittently extracted out, opposite side is synchronously continuously intermittently pushed into.Parallel gather of large number of above-mentioned high temperature tracheae is arranged in glass melting bottom of pond portion, adjacent tracheae spacing is not more than 40 centimetres, to realize the small flow of high-temperature gas, large area bubbling.
Description
Technical field
A kind of high-temperature gas bubbling fusing production method of the melting method of glass, particularly glass.
Background technology
In the production of various glasswares, the fusing of glass is mostly important production link.But so far, by glass
Glass melting sources are available for molding grade glass liquid, are all that glass metal surface carries out radiant heating in molten bath using flame
Mode carry out.The drawback is that 1, energy waste is extremely serious；2nd, gas exhaust emission is serious；3rd, the melting rate of melting furnaces is low,
Huge structure is complicated, and construction cost is very high.The method that the fifties foreign countries proposed submerged combustion, i.e., spray into glass by high-temperature fuel gas
In glass liquid, glass metal is rolled, so that heat is transmitted to glass metal in a manner of three kinds of convection current, conduction and radiation, can greatly carry
High thermal efficiency, melting rate simultaneously reduce exhaust emission.Hereafter successively there are several countries, include the Qinhuangdao glass research and design in China
Substantial amounts of research work has been done before the eighties by institute.But all successively abandoned since several crucial technical bottlenecks can not be broken through
.The combustion gas specific discharge intensity that these technical bottlenecks are mainly 1, are sprayed into glass metal due to burning spray gun is big, causes glass
Glass liquid foamed, it is difficult to clarify；2nd, due to the change of viscosity of glass metal, cause fuel gas flow not stablize, often spray glass
Glass liquid level；3rd, scrapped from the burning spray gun of melting furnaces bottom insertion under the washing away of glass metal in the gas of high-temperature high-flow rate and quickly
But can not replace；4th, furnace refractory, the refractory material of especially melting furnaces bottom washes away erosion seriously, and greatly reduces molten
Kiln service life.
The content of the invention
To solve the above-mentioned problems, the high-temperature gas submergence bubbling the present invention provides a kind of glass melts production method,
It is characterized in that：The high-temperature gas that will be burnt, electromagnetic heating or heating plasma produce, in a manner of small flow, large area bubbling,
Blast in glass metal, then while by glass liquid heating, enable glass metal clarification and homogenization.
The invention has the beneficial effects that：Can effectively solve that lance ejection submerged combustion mode met with several big is difficult to gram
The technical bottleneck of clothes.Achieve the purpose that and the earth energy-saving and emission-reduction and reduce glass production cost, improve glass production quality.
Embodiment
The bubbling device of above-mentioned high-temperature gas is the high temperature resistant tracheae for crossing glass melting pond；Above-mentioned high-temperature gas is blasted
This high temperature resistant tracheae, and at least row's bubble holes by being opened up on tracheae side wall, high temperature bubble is blasted in glass metal；
This design, can be by making tracheae in glass melting pond side continuously intermittently extraction, opposite side synchronous continuous interval push-in
Mode, makes tracheae constantly be able to renewal and replaces.So as to ensure the permanently effective use of tracheae.
Parallel gather of large number of above-mentioned high temperature tracheae is arranged in glass melting bottom of pond portion, adjacent tracheae spacing is little
In 40 centimetres, to realize the small flow of high-temperature gas, large area bubbling.
