Description

Waste heat recovery device for cooling fused quartz Technical Field The utility model relates to the technical field of quartz processing heat recovery, in particular to a waste heat recovery device for cooling fused quartz. Background The fused quartz needs to be precisely cooled after being molded at high temperature to avoid defects such as thermal stress cracks, devitrification (devitrification) and the like, and the traditional cooling mode usually adopts natural cooling or forced gas convection cooling, but the following problems exist in the methods: (1) And energy is wasted, namely, a large amount of high-temperature waste heat (500-1200 ℃) is directly discharged to the environment in the process of cooling the fused quartz to room temperature from above 1700 ℃, and the fused quartz cannot be effectively recycled, so that the energy consumption is high and the production cost is increased. (2) The cooling uniformity is poor, and the traditional cooling mode depends on radiation and gas convection, so that the cooling rates of different parts of the quartz product are inconsistent, thermal stress is generated, and the product quality is affected. (3) The existing cooling system is difficult to accurately adjust the cooling rate, and cannot meet the cooling requirements of quartz products with different specifications (such as slow cooling of thick-wall products and quick cooling of the thin-wall products). (4) The service life of the equipment is short, and the material of the inner wall of the cooling chamber is easy to be subjected to thermal shock and chemical corrosion (such as SiO 2 vapor corrosion) under the high-temperature environment, so that the refractory material is peeled off, and the maintenance cost is high. At present, partial waste heat recovery technology (such as heat exchangers and regenerative combustion systems) is applied to metallurgical and glass industries, but the following parts which need to be improved still exist for high-temperature waste heat recovery in the cooling process of fused quartz, such as the fact that a common metal heat exchanger cannot withstand the extreme temperature of more than 1000 ℃ for a long time, and the volatilized SiO 2 vapor of the fused quartz is easy to deposit on the heat exchange surface, so that the heat transfer efficiency is reduced, and the equipment needs to efficiently recover the waste heat and avoid interfering with the production process while ensuring the cooling uniformity; therefore, there is a need for an efficient, high temperature resistant, precisely temperature controllable fused silica cooling waste heat recovery device that addresses the above-described issues.
