Description
Technical field
The utility model belongs to glass technology for making field, is specifically related to a kind of total oxygen spray gun of gas-firing.
Background technology
Glass smelting is a most important production link in the glass production process, and the fabrication cost of modern large glass melting furnaces is very expensive, and kiln generally has only 5-8 age, and in process of production, the maintenance cost of melting furnaces is also very huge.Along with the enhancing of people's environment protection, Sustainable development consciousness, the development utilization Sweet natural gas has the energy shortage of alleviation situation, control atmosphere pollution, the trend of the times of improving the quality of living.In addition, the competition of global glass industry constantly aggravates, and is more and more high to the requirement of melting furnaces economy, requires the use of melting furnaces the smaller the better to the influence of environment again simultaneously.Under this background, adopt the combustion of natural gas technology to seem extremely important.Sweet natural gas has calorific value height, steady quality, device simple, is convenient to control and advantages such as low price and minimizing pollution as geseous fuel.Therefore, glass industry changes gas-firing to existing glass melter into by fuel oil, not only reduces price of fuel, reduces environmental pollution during burning, and more helps the glass industry technical progress, adjusts the currently available products structure, the quality products that the production added value is higher.
Because air-breathing float glass smelting kiln technology exists problems, glass quality is not high, and greenhouse gases and dusty gas discharging are more serious, the glass yield rate is low etc., under this environment, pure oxygen combustion technology obtains favor as a kind of practical technology, and full-oxygen combustion has following characteristics:
1) reduces discharging the protection environment
Pure oxygen combustion technology reduces the NO in the waste gas
xContent is because N
2In firing system, do not exist substantially.It is glass industry control NO
xThe best-of-breed technology approach of discharging.Glass full-oxygen combustion per ton makes NO
xDischarging reduce to 0.25～0.7kg by 2.7～4.5kg, reduce more than 70%.The smoke discharge amount that melting furnaces produce is from 34356m
3/ h drops to 8056m
3/ h, waste gas reduces by 70%～80% than the smoke discharge amount of air-breathing system; Low 150～the 250mg/m that reaches of dust discharge amount
3, reduce by 70%～80% than air-breathing system.
2) glass quality and output
Because full-oxygen combustion flame heat-transfer capability significantly improves.Make the glass metal deep layer obtain heating, pond bottom glass liquid temp raises; Add glass fluid and a large amount of steam reaction, OH-increases, and viscosity reduces, and is easy to the eliminating of bubble in the glass metal, helps clarification and homogenization.Full-oxygen combustion has improved the temperature of metal level simultaneously, and the water yield also increases in the flue gas, can quicken melting process.Compare with the air aid burning, under the prerequisite of fusing same glass quality, glass metal can absorb more heat, and glass output is improved.
3) reduce the initial stage construction investment
The full-oxygen combustion melting furnace structure is also simpler than unit kiln, no metallic recuperator and port, regenerator.The kiln body is a melting end monomer structure, takes up an area of for a short time, and the investment cost of putting up a kiln is low.Maintenance cost is low, and full-oxygen combustion can be saved the investment of putting up a kiln and reach 40% more than.Even add the cost of oxygen generating plant, the initial stage construction investment also decreases.
Over nearly 20 years, full-oxygen combustion melting furnaces technology has substituted air heat accumulating type or heat exchange type melting furnaces gradually.The middle and later periods nineties, European and American countries constantly discloses fuel, electric power, oxygen demand and the cost of relevant full-oxygen combustion melting furnaces and the information of initial cost aspect.The subject matter that pure oxygen combustion technology exists in application: the spray gun of the blast tube of full-oxygen combustion melting furnaces is the introducing port of a circle, natural gas and oxygen mix enter the inside of glass melter together from introducing port, efficient and effect are not ideal, while construction operation cost height, the acquisition of full-oxygen combustion complete set technology and the scale of investment of engineering etc., simultaneously, worry the influence of refractory corrosion to melting furnace life-span or glass quality.
