Description

Energy-saving cooling device for fused quartz Technical Field The invention belongs to the technical field of fused quartz, and particularly relates to an energy-saving cooling device for fused quartz. Background After the fused silica articles are formed by high temperature processing, the fused silica articles are subjected to a cooling process from thousands of degrees of high temperature to nearly room temperature. At present, the common cooling mode mainly depends on natural cooling in the environment or is assisted by low-temperature airflow to directly blow on the surface of the quartz cylinder. However, the natural cooling period is extremely long, and the production efficiency and the equipment turnover rate are severely restricted. When forced cooling is adopted, the cooling is accelerated to a certain extent, but the mode is extensive, the heat exchange efficiency is low, the energy utilization rate is not high, and the current industry trend of energy conservation and environmental protection is contrary. In the prior art, a remarkable physical contradiction exists that in theory, the hot air on the quartz surface can be blown away more quickly by increasing the flow rate of the cooling air flow, so that the cooling rate is improved. However, in practice, too high a flow rate can result in too short contact time between the air flow and the high-temperature surface, and heat is not fully absorbed and is separated, so that the efficiency of single heat exchange is reduced, and waste of air flow power resources is caused. This "flow rate and efficiency" discrepancy constrains further optimization of the cooling effect.
