Technical field
The present invention relates to glass furnace, especially relate to the toughened glass insulator glass furnace.
Background technology
As everyone knows since glass insulator to have self-cleaning good, be difficult for aging, insulating property are high, physical strength is high and null value from broken characteristics, thereby be widely used in power sector.At present; The manufacturer of glass insulator generally all adopts fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace that production glass insulator frit is carried out fusion formation glass metal and produces glass insulator; Fuel oil (combustion gas) is though heat accumulating type horse shoe flame glass furnace has the capable length of fireworks flame, burning is more complete; Less investment, energy consumption is lower and easy-operating advantage; But there is following point in fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace: the one, in combustion processes, can produce toxic and harmfuls such as a large amount of sulfurous gas and carbon monoxide, and bring severe contamination to atmosphere, the infringement health of human body and the eubiosis; The 2nd, because fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace inside needs to keep pressure-fired; Thereby a lot of in process of production foam glass raw materials can evaporate in company with flue gas and form dust pollution in the atmosphere; This dust is tiny generally with the naked eye can't be distinguished, is the direct generation reason of glass industry occupational illness, silicosis; The 3rd, the corrosion of the refractory materials experience high temp glass liquid in fuel oil (combustion gas) the heat accumulating type horse shoe flame glass furnace is washed away and can be made its upper layer come off erosion, damage seriously; Refractory materials that comes off and high temp glass liquid form calculus; Cause a large amount of waste products, the product loss ratio is up to 10-30%, and generation potential hidden danger of quality; Shorten the life cycle of glass furnace, improved the production run cost of glass furnace; Be that fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace is in operational process again; Reason such as change during because of flame trend and length; Temperature in the kiln exists inhomogeneous state; Thermal regulation is unstable all the time, and directly the capability and performance of aspects such as its insulating property of glass insulator of influence production and physical strength has fluctuation.
Summary of the invention
Problem to the existence of above-mentioned prior art intermediate fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace; The invention provides a kind of toxic and harmful and dust of not producing; Can improve glass insulator insulating property and physical strength, and can prolong life cycle, all electric melting insulator glass furnace that reduces production costs.
The technical scheme that the technical problem that the present invention will solve is taked is: said all electric melting insulator glass furnace comprises melting pool, distributing reservoir and feeder channel; Said melting pool is mainly formed by outer wall, thermal insulation layer, liner, furnace roof and furnace bottom; The melting pool below links to each other with distributing reservoir with last flow liquid passage through fluid port; Distributing reservoir links to each other with feeder channel, above melting pool, is provided with charging opening, melting pool, fluid port, on be arranged at intervals with electrode respectively in flow liquid passage and the distributing reservoir; Said melting pool vertically is provided with, and said melting pool inner chamber xsect is the limit number and is at least orthohexagonal ring texture.
In order to improve the abrasion resistance of all electric melting insulator glass furnace liner, said all electric melting insulator glass furnace liner all adopts the electric fused zirconium corundum brick of no shrinkage cavity cast to build by laying bricks or stones and forms.
The present invention has the following advantages:
1, all electric melting insulator glass furnace adopts electric smelting, and fireless burning in the production does not produce toxic and harmfuls such as sulfurous gas and carbon monoxide, can not cause topsoil, helps environment protection,
2, all electric melting insulator glass furnace adopts cold top closed to feed intake, and can not establish flue system in the kiln, can in atmosphere, not form dust pollution, smoke pollution, belongs to low-carbon emission,
3, all electric melting insulator glass furnace furnace wall refractory corrodes little; Because of refractory materials come off form calculus cause product loss in all electric melting insulator glass melting furnaces later stage ratio greatly about 0.3%; Its product loss ratio have only fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace later stage product loss ratio less than a thirtieth; And its life cycle is compared with fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace and has been improved more than the twice
4, all electric melting insulator glass furnace adopts the fusing mode of vertical stratification; Glass can all experience identical thermal history; Thereby the glass metal homogeneity is high, more helps the glass metal fusion, and it is inhomogeneous and cause toughened glass self-explosion to take place to have significantly reduced the glass metal internal structure; Improved the insulating property and the physical strength of glass insulator, and the glass melting rate of comparing fuel oil (combustion gas) heat accumulating type horse shoe flame glass furnace has improved about 78%.
5, all electric melting insulator glass furnace adopts full electrofusion, and temperature error is little between the set electrode points, and heating is evenly distributed, and the temperature of glass liquid good uniformity is convenient to temperature and is grasped and regulate, and operates also very convenient.
The present invention adopts the electric glass melting technical application to the glass insulator production industry, utilizes to be in the characteristic that molten state lower-glass liquid is the good conductor of electricity, with interelectrode high temperature glass is vertically melted; Reach fast, equal even free of contamination melted states, both improved the quality such as insulating property and physical strength of glass insulator, also improved the melting efficiency of electric smelting glass furnace; Reduced production cost; Increase economic benefit, and more helped environment guarantor stove, belonged to low-carbon emission.
