Description
Technical Field
The utility model relates to the field of glass production and manufacturing, in particular to an oxygen supply stabilizing device for a total oxygen glass kiln. On the basis, the utility model also relates to a glass kiln system comprising the oxygen supply stabilizing device.
Background
Glass melting is one of the main processes in glass manufacturing, and is a process of transferring heat to batch materials through combustion of fuel, thereby achieving the purpose of melting. The traditional glass melting adopts a glass kiln with a regenerator, the oxygen of the combustion improver is derived from air, the oxygen content of the air is only 21%, and the rest of the oxygen is nitrogen which is not beneficial to combustion. During the combustion process, nitrogen is heated, and on one hand, a large amount of heat is taken away; on the other hand, under high temperature, the nitrogen and the oxygen react chemically to generate NO and N 2 O and NO 2 And nitrogen oxides, causing air pollution. In the traditional glass kiln, the heat loss of the flue gas accounts for 25-35% of the total energy consumption, and the nitrogen in the flue gas accounts for about 75% and 18.75-25.25% of the heat loss of the flue gas. The large amount of flue gas not only can carry more dust to discharge to the atmosphere, seriously pollutes the environment, but also can cause the damage of waste heat recovery equipment such as regenerator and chimney more easily.
In the prior art, aiming at the technical problems of the traditional glass kiln, the glass kiln adopting the total oxygen combustion technology is characterized in that industrial oxygen is used for replacing air to form an oxygen+fuel combustion system, and compared with the traditional air-assisted combustion technology, the combustion mode of oxygen+fuel is adopted, combustion-supporting medium is changed into oxygen from air, the introduction and removal of about 78% of nitrogen are reduced, the flame temperature and heating efficiency can be improved, the smoke quantity is greatly reduced, the smoke exhaust heat loss is reduced, and the like. However, to stably melt high quality glass liquid, a reasonable stable temperature and temperature distribution must be provided in the oxy-fuel glass furnace, while the stability of the flame combustion atmosphere is ensured, which requires that the combustion control system be capable of precisely controlling the flow rates of the effective fuel gas (according to the calorific value and the oxygen gas (according to the content) required in real time for each burning gun of the properly arranged glass furnace, so as to ensure that the heat generated by combustion meets the requirements of the temperature and the temperature distribution, and simultaneously ensure that the oxygen concentration in the flue gas after the fuel combustion is stable (when the melting process requires an oxidizing atmosphere), or the concentration of the reducing component is stable (when the melting process requires a reducing atmosphere), and the stability of the combustion atmosphere reaches the furnace.
However, the oxygen content of pressure swing adsorption production used in the total oxygen glass kiln can fluctuate within a certain range, and is influenced by certain factors (such as voltage fluctuation, cooling water temperature change, equipment failure, improper operation and the like), and sometimes the fluctuation range is larger and exceeds the design application range requirement; the oxygen content produced by the oxygenerator in the later use period of the oxygen-producing molecular sieve can be lower than the combustion requirement of the kiln; during heavy faults of the oxygenerator and periodic maintenance of the oxygenerator every year, liquid oxygen is needed to temporarily replace oxygen produced by pressure swing adsorption, and the oxygen content supplied in the cases can be greatly changed. Because the combustion control system in the prior art only carries out standard state conversion on real-time temperature and real-time pressure in the process of controlling the oxygen flow rate, but does not carry out standard conversion on fluctuation of the oxygen content, when the oxygen content is changed, the flow rate of effective oxygen (measured according to the oxygen content) entering the kiln can be changed along with the change, thus the change of the temperature and temperature distribution in the kiln and the combustion atmosphere can be caused, and the adverse effect on melting high-quality glass liquid is generated, thereby influencing the production. And even if the standard state conversion is carried out on the oxygen content to carry out the flow rate control, the mode of increasing the oxygen supply quantity is adopted, the state in the kiln can be greatly or slightly influenced, and thus the problem of unstable state in the total oxygen glass kiln is caused.
