In life, waste glass has become one of the most difficult substances to deal with in urban waste because it cannot be degraded, and if glass bottles are mixed with other garbage and disposed of in traditional landfills, it will not only waste energy, bring pollution, but also waste a lot of land resources.
According to the current needs of glass production, at least 17%-30% waste glass is added per ton of glass. According to statistics, the use of recycled glass to regenerate glass can save 10%-30% of coal and electricity energy, reduce air pollution by 20%, and reduce the exhaust gas of mining waste by 80%. Calculated by one ton, recycling one ton of waste glass can save 720 kg of quartz sand, 250 kg of less soda ash, 60 kg of feldspar powder, 10 tons of coal, and 400 kWh of electricity. One ton of waste glass can recycle 20,000 500g bottles after being recycled, which is 20% less cost than using new raw materials for production. As a result, the economic and environmental benefits of recycled glass are considerable.
At the same time, the quality of glass sorting has become a problem for recycling. In the process of recycling, waste glass will produce a large amount of CSPQ (insoluble matter), such as: discoloration, stones, various metals, plastics and other household waste. The presence of these malignant impurities results in materials that must be processed before they can be reused, as glass container manufacturers need to use high-purity raw materials.
In the traditional waste glass recycling process, after the raw materials are crushed, they enter the drum cleaning equipment, and after cleaning, they enter the manual selection platform to manually select malignant impurities such as heterochromatic impurities, light substances, and CSF that may interfere with the furnace operation.
Although manual selection is simple, it has the disadvantages of high labor cost, low sorting efficiency, and difficult to ensure sorting quality.
Through the identification of broken glass, Wenyao intelligent glass color sorter can be classified according to different colors, and at the same time remove stone, ceramic, metal and other insoluble impurities in the broken glass, so as to obtain the broken glass raw materials with uniform color and very low impurities.
At present, the average recycling rate of waste glass in the world is only close to 50%, and the market space of waste glass industry is huge. Wenyao tech will continue to improve waste glass with advanced intelligent sorting technology
Glass quality, promote the establishment and improvement of the recycling and processing system, so that more waste glass can be reborn.
