No matter the glass is plate glass, bottle glass, glass or glass fiber, a certain amount of waste materials are generated in the production process, some waste materials have the same components with the original product, some waste materials have different components with the original product, such as glass fiber, and an impregnating compound needs to be coated in the production process, so the organic composition has the functions of reinforcement and protection, and the glass fiber waste materials cannot be directly buried in soil, otherwise the properties of the soil can be changed, and the direct discarding causes great harm to the environment.
If the waste materials can be partially doped into qualified production raw materials and re-melted to regenerate products, the problems can be solved to a certain extent. However, in the prior art, the waste is directly added, the production process does not conform to the original automatic powder conveying and feeding process, and the equipment is not completely applicable, so that the waste is ground into powder before feeding, and then the powder is added into the original mixed materials according to a certain proportion. Because the waste material contains a certain amount of impurities which are difficult to remove, the addition of the waste material into the original mixture can cause the yield of the product to be reduced to some extent, and the quality of the product is also influenced to a certain extent. In order to ensure the product quality and the yield, the addition amount of the waste raw materials can only be controlled at a lower proportion, so that the waste consumption rate is greatly reduced and even possibly lower than the yield of the waste, and further the environmental protection risk still exists.
How to treat the solid waste materials is always a great problem which troubles manufacturers of glass, glass products and glass fibers, especially the production of the glass fibers, because the waste materials contain higher organic matters, if the waste materials are directly put into a kiln, the oxidation-reduction atmosphere of the kiln can be changed, so that the production environment and the production process become very unstable, and the production process and the product quality are difficult to control.

Fig. 2 shows a schematic internal side view of an embodiment of the furnace 2, fig. 3 is a schematic top view of the furnace 2, and in combination with fig. 2 and 3, one end of the furnace 2 is provided with a flow channel 21 for outputting molten glass. The flow channel 21 and the batch feeder 1 are respectively located at different ends of the furnace 2, for example, when the batch feeder 1 is arranged at the end surface or the side surface of the first end of the furnace 2, the flow channel 21 is located at the second end of the furnace 2 opposite to the first end, and the glass liquid flows along the flow channel 21 towards the second end of the furnace 2. Illustratively, the inside of the kiln 2 can be divided into a feeding area and a melting area according to the material state, the feeding machine 1 is communicated with a feeding port on the side wall of the feeding area, and the materials in the feeding area mainly comprise glass and/or glass fiber waste and a part of molten glass; the material in the melting zone is molten glass, so the feeding zone and the flow channel 21 are respectively positioned on different sides of the melting zone.
In this embodiment, at least one burner 23 is disposed at the top of the furnace 2 for melting glass and glass fiber waste materials introduced into the furnace 2 to form molten glass. Since the burner 23 is located at the top of the furnace 2, the surface temperature of the molten glass in the furnace 2 is higher than the bottom temperature.
In an alternative embodiment, the inlet of the flow channel 21 is arranged higher than the inner bottom surface of the kiln 2 and is used for obtaining the high-temperature molten glass on the upper layer in the kiln 2, so that only the high-temperature molten glass on the upper layer flows, but the molten glass on the bottom of the kiln 2 does not flow basically, which is beneficial to slowing down the erosion of the refractory material on the bottom of the kiln, prolonging the service life of the kiln and reducing the heat consumption. Under the general condition, the depth of the glass liquid in the kiln 2 is less than or equal to 80cm, and the height difference between the inlet edge of the flow channel 21 and the inner bottom surface of the kiln 2 can be set to be 20-60 cm, so that only the glass liquid on the surface layer is ensured to be in a flowing state and flow into the flow channel 21 in real time, and the glass liquid lower than the inlet height of the flow channel 21 is in a basically static state, so that the corrosion to the bottom of the kiln 2 is effectively slowed down, and meanwhile, impurities in the raw glass and the glass fiber waste can be precipitated.
Further, the export of runner 21 is less than the entry setting of runner 21 to guarantee the smooth and easy nature of flow of top glass liquid, simultaneously, can deepen the glass liquid degree of depth in runner 21 exit, increase the pressure of glass liquid, promote the smooth and easy nature and the outflow efficiency that the glass liquid flows out.
In an alternative embodiment, the inclination angle γ of the flow channel 21 is smaller than 30 °, for example, the inclination angle γ of the flow channel 21 can be set to 7 °, 8 °, 13 °, or the like.
In an optional embodiment, the outlet of the flow channel 21 is provided with a discharging hole 24, and the molten glass is discharged through the discharging hole 24 and then water quenched to generate round and smooth glass slag, so that resource recycling of glass and glass fiber waste is realized, and harm to the environment is reduced. The proper aperture of the discharging hole 24 is beneficial to smooth outflow of glass liquid, ensures the size of generated glass slag, and facilitates subsequent drying, transportation and the like. Illustratively, the diameter of the discharge hole 24 is generally 20-200 mm, for example, it may be 56mm, 80mm, 124mm, etc. Wherein, the shape of the discharge hole 24 can be circular, oval or polygonal. In the present embodiment, the shape of the discharging hole 24 is not particularly limited, and any discharging hole shape that facilitates the outflow of the molten glass and the formation of the glass slag with a suitable size is suitable for the present embodiment and should be understood to be within the scope of the present invention.
Further, a discharging orifice 25 is provided at the outlet of the discharging hole 24 to adjust the discharging aperture, speed, etc. of the molten glass. Illustratively, the discharge nozzle 25 may be disposed proximate the outlet of the discharge orifice 24. In an alternative embodiment, the discharge leakage board 25 may be provided with a temperature control module electrically or in signal connection with the regulator and the DCS system, so as to adjust the temperature of the discharge leakage board, and realize thermostatic control and adjustment of molten glass discharge.
In the kiln 2 of the regeneration equipment of the invention, a kiln flue 22 is arranged above the outlet of the flow channel 21, and the high-temperature waste gas generated in the kiln 2 is used for heating and insulating the molten glass in the flow channel 21. The kiln flue 22 is arranged above the outlet of the flow channel 21, so that the flowing direction of high-temperature waste gas and the flowing direction of glass liquid in the kiln 2 can be consistent in the process that the glass liquid flows to the flow channel 21, and the flowing glass liquid can be heated and insulated in real time by using the waste heat of the high-temperature waste gas, so that the high-temperature melting state and the flowing smoothness of the glass liquid can be further ensured; meanwhile, high-temperature waste gas is continuously discharged from the kiln flue 22, so that waste heat of the high-temperature waste gas entering the kiln flue 22 can be used for heating and preserving heat of the outlet of the runner 21 below the kiln flue 22 in real time, the temperature and the flowing smoothness of the molten glass at the outlet of the runner 21 are ensured, and the glass is effectively prevented from being condensed and solidified at the outlet of the runner 21 far away from the burner 23 to cause blockage. By the arrangement mode of the kiln flue 22, the waste heat of high-temperature waste gas is fully utilized, heating parts such as a combustion gun and the like are not required to be additionally arranged in the space corresponding to the flow channel 21, the complexity and the maintenance cost of equipment are greatly reduced, and meanwhile, the heat consumption is greatly reduced, and the energy is saved.
Referring back to fig. 1, the recycling apparatus of the present invention further includes a water quencher 3 communicating with an outlet of the flow passage 21 for cold quenching the molten glass into glass slag. In this embodiment, the water quenching device 3 is located below the discharging hole 24, and the molten glass discharged through the discharging hole 24 and the discharging bushing 25 directly enters the water quenching device 3 to be cold-quenched into glass slag, so as to realize recycling and resource utilization of glass and/or glass fiber waste.
In an alternative embodiment, the regeneration equipment of the present invention further comprises a cooling pool 4 in communication with the outlet of the water quencher 3, and a tunnel oven 5 in communication with the cooling pool 4. The glass slag formed by water quenching in the water quenching device 3 has a higher temperature, can not be directly packed and conveyed, even has the risk of re-adhesion and the like, is inconvenient for subsequent direct use, and therefore needs to be cooled. As shown in fig. 1, the water-quenched glass slag in the water quencher 3 can be transported to the cooling bath 4 through a cooling transportation pipeline 31 for sufficient cooling. The cooled glass slag is conveyed to the drying conveyer belt 51 through the cooling conveyer belt 41, and enters the tunnel oven 5 along with the operation of the drying conveyer belt 51 for drying. The glass slag dried by the tunnel oven 5 is a glass material which can be directly used, and can be conveyed to the packing device 7 by the conveyor belt 52 for packing, standby or sale.
In another alternative embodiment, the recycling apparatus further comprises a crushing device 6 for crushing the glass and glass fiber waste into desired particle sizes for easy transportation and feeding while improving the melting efficiency in the furnace 2. Wherein, the outlet of the crushing device 6 is communicated with the batch feeder 1, and the glass and/or glass fiber waste materials crushed by the crushing device 6 can be directly conveyed into the kiln 2 through the batch feeder 1.
Exemplarily, since the position of the kiln 2 is higher than the setting of the water quenching device 3, and the glass and glass fiber waste materials before being crushed are difficult to transport, in order to facilitate the crushing of the glass and glass fiber waste materials, the transportation efficiency is improved, the crushing device 6 can be arranged on the ground lower than the inlet of the kiln 2, and the glass and glass fiber waste materials after being crushed by the crushing device 6 are conveyed to the batch feeder 1 by the bucket elevator 11.
In an alternative embodiment, the crushing device 6 may be a crusher.
By using the regeneration equipment, the temperature in the kiln 2 needs to be maintained at 1500-1600 ℃, so that organic impurities contained in glass and glass fiber waste materials can be directly and completely combusted, and the generated waste gas is conveyed to a waste gas treatment system along a kiln flue 22 for purification treatment and then discharged, thereby effectively solving the problem of environmental pollution caused by organic leakage caused by direct landfill treatment of the waste materials in the prior industry. The non-metallic inorganic substances contained in the waste materials can be basically melted in the kiln to form a component of molten glass, and a component of solid glass slag is formed after water quenching, so that the reuse of the glass slag is not influenced, and the environment is not polluted.
The remaining impurities in the scrap, other than the non-metallic impurities, are metallic or alloyed impurities, the main constituent being iron or alloyed iron. The alloy iron has low melting point, can be basically melted in molten glass, forms a component of the glass slag along with water quenching, and does not influence the reuse of the glass slag; the large alloy iron which can not be completely melted sinks at the bottom of the kiln 2, and the flowing and water quenching of the surface glass liquid are not influenced. The temperature of the glass liquid at the bottom of the kiln 2 is only about 1100 ℃, the content of unfused alloy iron is very low, the quality of the glass liquid cannot be affected, the unfused alloy iron at the bottom of the kiln can be taken out through regular cleaning, smelting recovery is carried out in a smelting plant through selling, and the waste recovery rate is further improved.
While elemental iron, which affects the quality of the glass slag product and the use thereof, is mainly generated in the water quencher 3 and the cooling transfer line 31. In an alternative embodiment, ceramic linings can be arranged in the water quenching device 3 and the cooling conveying pipeline 31 to prevent the high-temperature molten glass from directly contacting with the inner walls of the water quenching device 3 and the cooling underwater sound pipeline 31 to generate iron impurities, so that the iron impurities in the glass slag are avoided. In another alternative embodiment, an electric magnetic attraction rod can be arranged on the packing device 7, so that iron powder in the glass slag can be removed.
Through the technical means, the glass and glass fiber waste containing impurities can be effectively prevented from being discarded or buried, organic matters, inorganic non-metallic impurities and metal/alloy impurities in the waste can be well treated and recycled, the recycling rate of the waste is greatly improved, the prepared glass slag can be used for producing various insulators and artware, and can also be added into building coating to produce decorative exterior walls, so that great economic benefits and social benefits can be generated.
In accordance with the recycling equipment, the invention also provides a recycling method for glass and glass fiber waste, which is realized by the recycling equipment.
