摘　　要：为了探究低压环境下冲渣水蒸发,搭建了冲渣水真空闪蒸试验平台,对冲渣水在压力为50~70 kPa条件下进行了实验研究,分析了真空条件下不同水位、进水流量、压力工况下冲渣水闪蒸特性,并对冷凝水品质进行分析。结果表明:随着压力的增大,蒸汽产量不断增大;对于相同压力下的冲渣水溶液,进水流量越大蒸汽量越大,闪蒸罐内水位越高蒸汽量越少;且闪蒸形成的冷凝水基本可以满足常规工业软水要求。研究成果有助于指导冲渣水余热利用的工业应用。In order to explore the evaporation of slag flushing water in a low-pressure environment,a vacuum flash evaporation test platform for slag flushing water was built.On the test bench,an experimental study was conducted on the slag flushing water at a pressure of 50~70 kPa.The flash evaporation characteristics of slag flushing water under inlet water flow and pressure conditions,and the quality of condensate water is analyzed.The results show that:with the increase of pressure,the steam output increases continuously;for the slag flushing water solution under the same pressure,the larger the inlet water flow,the larger the steam volume,and the higher the water level in the flash tank,the lower the steam volume;and flash evaporation The formed condensate can basically meet the requirements of conventional industrial soft water.The research results help to guide the industrial application of waste heat utilization of slag flushing water.
