Description
Technical Field
The application relates to a device for improving raw material melting efficiency in float glass production, and belongs to the field of float glass production.
Background
Float glass production is carried out by flowing molten glass continuously from a tank furnace and floating on the surface of molten tin with high relative density while introducing protective gas (N) into the tin bath2And H2) Under the action of gravity and surface tension, the molten glass is spread on the tin liquid surface, flattened, cooled and hardened to form glass with flat upper and lower surfaces. The obtained glass has good flatness, no water ripple on the surface of the glass, compact structure, smooth hand feeling, larger specific gravity per square meter than a flat plate with the same thickness, good cutting performance and difficult damage. The float glass is made of ore quartz sand, and the produced glass is pure, has good transparency, has no obvious defects such as glass furuncle, bubbles and the like, and can be widely used for manufacturing mirrors and automobile glass.
According to the statistics of the glass society of China, the total amount of 298 glass production lines in the national float glass production line is up to 2019, 12 and 31 days, and the daily melting amount is 160185 tons in 241 glass production lines. At present, China becomes the first world for manufacturing glass, and products produced by China are sold to the world and account for more than 50% of the global glass market share. But the glass manufacturing industry in China has weak whole innovation capability, high energy consumption and large resource consumption in the manufacturing process, and has a great gap compared with the advanced level in foreign countries.
In recent years, the combination of Chinese building materials and organizations such as the China building glass and industrial glass Association develop the innovation technology of the second generation float glass in China, the fuel cost accounts for more than 30% of the glass cost, the glass melting efficiency is improved, the fuel cost is reduced, and the improvement of the quality development is especially important for enterprise structure adjustment and realization of high quality development.
The fuel used in the glass production process is mainly used for melting the glass raw material, and in the glass melting process, mainly comprises a silicate forming stage and a molten glass forming stage, the whole process from mixing to molten glass forming is the most important and complicated stage in glass melting, at this stage, different batch ingredients, different feeding modes, different flame coverage areas and different convection modes all affect the melting efficiency, and unstable melting efficiency can cause deviation of glass components, inconsistent gas amount in the glass, even cause the prepared glass to contain stones formed by unmelted objects, and cause the quality of the glass to be reduced, therefore, the improvement of the melting efficiency and the reduction of the energy consumption in the glass melting process are of great importance to the cost reduction and the efficiency improvement of enterprises and the structure adjustment, meanwhile, the quality of the prepared glass is improved, and infusible calculus is prevented from being left in the glass.
In the prior art, the whole melting section of the glass raw material is heated at a higher temperature, especially the higher temperature is kept in the clarifying section, so that the raw material which is not melted in the glass raw material is melted, and the forming of furuncle (glass state inclusion) in the molten glass is avoided. However, the method does not increase energy consumption and production cost, and simultaneously increases the requirement on the accuracy of monitoring the temperature of the melting section of the kiln, once the temperature of the clarification section is reduced, the whole batch of glass is scrapped and the difficulty in controlling the production process is increased because fuel supplement is not found in time.
