Description
Technical field
The invention belongs to the specific equipment in the glass manufacturing area, relate to the structure design of the glass melting furnace of fusing high-boron low-alkali or non-alkali glass specifically.
Background technology
When present glass melting furnace carried out melting to the high-boron low-alkali of infusibility, difficult homogenizing or non-alkali glass, efficient was low, the hear rate height, and the effect of clarification, homogenizing is also undesirable.Resulting glass qualification rate is low and quality is not high.If will improve fusing, homo-effect, conventional innovative approach is to improve the technic index temperature, will certainly accelerate the erosion of refractory materials like this, shorten the work-ing life of tank furnace, and erosion aggravation along with refractory materials, the branch that mixes in the glass metal increases thereupon, thereby causes more glass defect, has reduced the quality percentage of glasswork.
Summary of the invention
The objective of the invention is to overcome the defective in the present tank furnace existing structure design, provide a kind of glass metal fusion quality height, thermo-efficiency height, energy consumption is low and the environmentally friendly tank furnace that is used for melting high-boron low-alkali or non-alkali glass specially, what particularly consider is efficient, energy-conservation concrete technical measures.
Technical solution of the present invention provides a kind of structure design that is used to melt the glass melting furnace of high-boron low-alkali or non-alkali glass, comprise heating system in the structure with the supporting setting of glass melting furnace, key is to comprise in the glass melting furnace internal structure the pre-molten bath that has opening for feed, the cross flame melting pool that links to each other with pre-molten bath, lower channel by the current limliting partition wall be communicated with the cross flame melting pool the cross flame settling pond, by the cross flame work pool that pipeline is communicated with the cross flame settling pond, the shaping channel of transporting molten attitude glass is arranged on the cross flame work pool (7).
Key Design thought of the present invention is fritting, fusing, clarification, homogenizing four parts that reasonably traditional melting pond are decomposed into glass, carries out work at regional space separately respectively.And subregion, the section supporting relatively independent heating and the management system of being provided with.Make each zone more convenient to management, the adjusting of temperature; Make fusing, clarification, homogenizing more timely, abundant simultaneously, in reasonable energy utilization, improved the glass metal quality.To pre-molten bath, the temperature of charging opening is lower, thereby has reduced the volatilization of the boron oxide in the raw material and other volatile component, so not only save raw material but also helped the stable of glass ingredient, simultaneously, the minimizing of volatile matter has alleviated the erosion of volatilization dust to refractory materials.Burning is the rapid reaction of fuel and oxygen.In this course, air is used to provide oxygen, 21% of oxygen duty gas.Yet, wherein 79% be N
2, it does not provide effect to burning.The NO that burning produces
x, also can pollute atmosphere.The employing total oxygen is combustion-supporting, has improved peak flame temperature, improves thermo-efficiency, also helps environmental protection.Can the subregion specific aim utilize electricity fusing-aid, add strong convection, force fusing, improve refining quality; Reduced the top flame space intensity of combustion, protected refractory materials, prolonged furnace life.The utilization of pond pucking bubble technology makes bubbling in the melting pool, has accelerated the clarification and homogenization process of glass metal, has improved heat passage between the dark direction glass metal in pond simultaneously, reduces temperature head, has improved melting capacity.In the further dark fusing of cross flame settling pond, shallow clarification technology: strengthen the work reserves of glass metal, shallow clarification, the convenient temperature that improves glass metal reduces the static pressure of deep layer glass metal, impels the eliminating of bubble.Whole tank furnace adopts all risk insurance temperature technique, reduces thermosteresis, has further guaranteed raising tank furnace thermo-efficiency.

Below in conjunction with accompanying drawing the present invention is further described.
Embodiment
Can go out the objective of the invention is to design a kind of glass melting furnace that is used to melt high-boron low-alkali or non-alkali glass by silkworm in conjunction with the accompanying drawings, comprise heating system in the structure with the supporting setting of glass melting furnace.Key is to comprise in the glass melting furnace internal structure the pre-molten bath 2 that has opening for feed 1, the cross flame melting pool 3 that links to each other with pre-molten bath 2, lower channel 4-1 by current limliting partition wall 4 be communicated with cross flame melting pool 3 the cross flame work pool 7 that is communicated with cross flame settling pond 5 by pipeline 6 of cross flame settling pond 5, the shaping channel 8 of transporting molten attitude glass is arranged on the cross flame work pool 7.
In above tank furnace heating system, use a kind of in the combustion-supporting Sweet natural gas of total oxygen or liquefied petroleum gas (LPG) or the Trimethylmethane gas, or any two or three mixed firing mode provides heat.
The above-described pre-molten bath 2 of glass melting furnace, cross flame melting pool 3, cross flame settling pond 5, cross flame work pool 7 row's of the string connection successively that is used for melting high-boron low-alkali or non-alkali glass.。
The lower channel 4-1 that is communicated with between cross flame melting pool 3 and the cross flame settling pond 5, cross flame settling pond 5 connect the pipeline 6 of cross flame work pool 7, the shaping channel 8 set level heights of transporting molten attitude glass raise successively.
Be included in the said heating system to have increased in the cross flame melting pool 3 and be electricity fusing-aid device 9, bubbling device 10.
Supporting flue at cross flame melting pool 3, cross flame settling pond 5, cross flame work pool 7 is arranged on breastwork, arch top or the headwall.
Level height raises successively at the bottom of the pond of cross flame melting pool 3, cross flame settling pond 5, cross flame work pool 7, and level height differs 300～500mm at the bottom of the pond of cross flame melting pool 3 and cross flame work pool 7.
Cross flame melting pool 3 and cross flame settling pond 5 parallel disjunctors are arranged, and realize being communicated with by the lower channel 4-1 of cutting apart the wall lower end.
Cross flame settling pond 5 is discrete with cross flame work pool 7 main bodys, realizes being communicated with by means of pipeline 6.
1-3 road shaping channel 8 is set on the cylindric pool wall of cross flame work pool 7.
Charging machine drops into admixtion from the charging opening 1 that is arranged on pre-molten bath 2.Because high-boron low-alkali or non-alkali glass are difficult to fusing, through fritting, help glass and reach abundant fusing in the melting area, reduced the moving cross flame melting pool 3 that enters of the boron oxide in the raw material simultaneously, admixtion heats through the electricity fusing-aid in combustion-supporting flame heating of the total oxygen on top and the glass metal in this zone, make and strengthened heat exchange in glass metal surface and inner with glass metal.Set bubbling makes glass metal produce the intensive convection current, thereby reaches the purpose of abundant fusing.Lower channel 4-1 by current limliting partition wall 4 lower ends enters into cross flame settling pond 5, because the high-boron low-alkali or the non-alkali glass of the difficult homogenizing of infusibility are difficult to clarification, adopt more shallow settling pond 5, can conveniently improve the temperature of glass metal, reduce the static pressure of deep layer glass metal simultaneously, impel bubble to get rid of fast.Can enter into cross flame work pool 7 through piping 6 for abundant clarifying glass metal, after 7 pairs of glass metals of work pool carry out homogenizing, glass metal enters shaping channel 8 according to assignment of traffic, satisfied the needs of moulding through the glass metal quality of shaping channel 8.
